Spoiler: Unlocking your bootloader (Required for all other tutorials below)
Step 1
Make sure you have a Mi Account ready.
You should've created one when first setting up your phone, with your phone number and a password.
- If you have it: Double-check you have access to it by attempting to connect on Xiaomi's official website (Login page).
- If you don't: Create one with the Create an account button below the password form (same link as above), then connect to it.
Step 2
On your PC, go to Xiaomi's unlock page and click the colored Download Mi Unlock button.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

}
Step 3
A download should start. Wait for it to finish, move the archive to your desktop and extract its content.
Step 4
Inside the extracted folder, double click the file called miflash_unlock.exe to start Xiaomi's Unlocking program.
Step 5
Read Xiaomi's Disclaimer then agree to their terms, or stop here and leave this thread if you don't.
Step 6
Sign in to your Mi Account we talked about in Step 1.
Step 7
Let's get your phone ready for unlocking.
Go to your phone's Settings > Mi Account and make sure you're logged in.
Now Settings > About Phone and tap the "MIUI Version" box multiple times until it says You are now a developer!
And finally Settings > Additional Settings > Developer Options
Enable the following settings inside Developer Options, and click Accept when warnings pop-up:
OEM Unlocking
USB Debugging
Still in Developer Options, check your Mi Unlock status and click the Add account and device button at the bottom if present.
Make sure to backup your phone's data before continuing on with this tutorial, as unlocking will make it factory reset (wipe)!
Step 8
Alright, all backed up? Confident? Let's get going with the final steps.
Turn off your phone.
Turn it back on into fastboot mode by holding down the Power button AND Volume Down together until it vibrates, you may then let go of the Power Button, but keep Volume Down held until you see the fastboot image on your phone.
Connect your phone to your computer with the USB Cable.
Xiaomi's Software should detect it. If not, click on the cog-wheel in the top right, click the Check button to install the driver and follow instructions, then keep going.
Click Unlock, and follow the instructions!
Now there are two possible scenarios
Either you've done all this before and can have your phone unlocked right away.
Or this is the first time and at the end of the progress it'll ask you to wait ~7days, and, well, there's no way around that, so come back in 7 days and start from Step 8 again.
And there you go! Your phone will reboot and you can set it all up again, with the ability to follow the rooting tutorial below, and you can also install custom ROMs/recovery!
Spoiler: Rooting (Magisk)
Step 1
Download the latest Magisk .apk on your phone.
Go to the link above, click the latest (topmost) Magisk-vXX.X.apk you see in the list to start the download, open the file and install it.
Step 2
Go to the download page for the MIUI Official Rom for your region, make sure to get the fastboot version.
OR (if you don't want/can't download 3gb of ROM)
Follow DavitidzeSh's instructions on how to gather the boot.img and vbmeta.img files and SKIP to Step 5.
OR (if you're on a custom rom)
Look into your custom rom's .zip, find the boot.img and vbmeta.img files and SKIP to Step 5.
Step 3
Take the file you downloaded above, it should be a .tgz archive.
Extract it, you'll get a .tar achive.
Extract that one again.
Step 4
You should now have a folder similar to the one below
Go inside the images folder
Step 5
Grab the the vbmeta.img file and copy it to your ADB & Fastboot (Platform Tools) folder.
Grab the boot.img file and copy it to your phone's internal storage.
(where the Android, DCIM, Download, and more are present, just drop it in there)
Here's how it should look inside your phone's storage in the end.
Step 6
On your phone, open up Magisk Manager.
Click the Magisk Install button as shown below.
Then Select and Patch a File.
Go look for your boot.img you previously copied to your phone and pick it.
Click Let's go! and wait for Magisk to complete the process!
Step 7
Link your phone to your PC, grab the file made by Magisk Manager.
It's located in your phone's downloads folder, called magisk_patched.img.
Copy and paste it where your ADB & Fastboot (Platform Tools) are located.
You should now have a folder structure like this:
adb.exe
fastboot.exe
magisk_patched.img
vbmeta.img
Extra files from the platform tools
Step 8
Alright, we're ready to root!
Turn off your phone, then get in fastboot mode.
(Power + Volume Down, like the unlocking tutorial)
Step 9
Link your phone to your PC with the USB cable if not done already.
Step 10
Shift + Right click in an empty space inside the folder we prepared in Step 7,
And click Open PowerShell window here.
Inside the PowerShell window, input the following commands line by line, in order.
.\fastboot.exe devices
Click to expand...
Click to collapse
Make sure your device shows up, should be a bunch of numbers and letters, a couple spaces, and fastboot.
If nothing does, go back to Step 8 and try again.
.\fastboot.exe --disable-verity --disable-verification flash vbmeta vbmeta.img
.\fastboot.exe flash boot .\magisk_patched.img
.\fastboot.exe reboot
Click to expand...
Click to collapse
Note: Your PowerShell window will look different, I'm using a different program, don't worry
Your phone will reboot.
Open up Magisk Manager, and double check that it's installed.
You're done!
That said, you will have issues with certain apps leaving it like this.
You should to hide the fact that your phone is rooted.
Check out the Passing SafetyNet tutorial further down below!
Spoiler: Getting EdXposed
I very much discourage to EdXposed your phone unless you have a very good reason for it.
It's a pain to pass SafetyNet.
It doesn't get updated often.
It has very niche use cases for which it's actually worth it.
That said, I explain it here for people who know what they're getting into and want instructions on how to do it.
This procedure requires to be rooted with Magisk.
Step 1
Inside Magisk Manager, go to the Modules tab.
Click the search button (bottom right) and search Riru.
Install the Riru module by Rikka.
Activate it and Reboot.
Step 2
Download and install the latest EdXposed Manager, the same way you did with Magisk Manager when rooting.
Step 3
Open it up, go to the ALPHA tab and click install/update.
It'll start a file download.
Step 4
Go back to Magisk Manager, Modules tab, except this time click Install from Storage.
Point to the .zip file you just got, located in the Downloads folder of your phone.
At the end of the installation, click reboot.
Step 5
Let's double check your installation is operational.
Go to EdXposed Manager, first tab.
It should say EdXposed Framework is active.
You're done!
You should now be able to install EdXposed modules.
That said, you will have issues with certain apps leaving it like this.
You should to hide the fact that your phone is EdXposed.
Check out the Passing SafetyNet tutorial further down below!
Spoiler: Passing SafetyNet (Magisk/EdXposed)
For Magisk Rooted Phones
Enable Magisk Hide inside Magisk Manager's settings.
You may also need to use the Props module to spoof your phone as another, if you want a tutorial on that, let me know.
For EdXposed Phones
Again, I highly recommend not EdXposing your phone and sticking to just Magisk if you can help it.
You should also know that this method will show you're passing SafetyNet inside Magisk but it's a pain to do and isn't as well hidden as Magisk alone.
Step 1 - Do the step for Rooted phones listed above if not done already.
Step 2 - In EdXposed Manager, get the HiddenCore Module and activate it.
Step 3 - Now, in the side-menu: Compat List > tick HiddenCore Module.
Step 4 - Then, go to Settings > Framework > Enable "App List mode".
Step 5 - Finally, Applications(Black List) and tick: Android Services Library, Chrome, Google Play services, Google Play Store, Google Services Framework
Reboot and enjoy! You're all set and SafetyNet should pass.
Spoiler: Installing GSI's (Non-device specific ROMs)
Step 1
Pick your poison in the Treble Forums!
My recommendations are in the Extras section of this post.
Step 2
Download the chosen ROM's A/B Arm64 version
It should be an .img.xz file
Extract it and you'll get an .img file.
You're almost ready to flash.
Make sure to backup your phone's data.
Continuing this tutorial will wipe your phone!
Step 3
Put your phone into fastboot mode.
(Power + Volume Down)
Connect it to your PC.
Step 4
Move the .img file you downloaded to your ADB & Fastboot (Platform Tools) folder.
Rename it to system.img
Step 5
Shift + Right click in an empty space inside the folder,
And click Open PowerShell window here.
Inside the PowerShell window, input the following commands line by line, in order.
.\fastboot.exe reboot fastboot
.\fastboot.exe --disable-verification flash vbmeta .\vbmeta.img
.\fastboot.exe flash system .\system.img
.\fastboot.exe -w
.\fastboot.exe reboot
Click to expand...
Click to collapse
Your phone will now reboot on its own.
Set it all up and enjoy!
That said, depending on how old the GSI you picked is, you MAY have issues leaving it at that.
Therefore, I highly recommend checking out the next tutorial section about Fixing GSI Issues.
Spoiler: Fixing brightness/jack on older GSI's
I have worked together with a developer to bring fixes for our device to every custom GSI rom out there.
The most recent GSI's shouldn't need the fixes listed below.
Older GSI (treble) roms have two known bugs that we can fix:
The brightness slider being misscalibrated, and therefore auto-brightness broken too.
The headphone jack not working.
You need to be rooted to do so.
Step 1 - Get yourself a Terminal Emulator, I recommend Termux
Step 2 - Type the following commands inside of it, line by line, in order:
su
setprop persist.sys.qcom-brightness $(cat /sys/class/leds/lcd-backlight/max_brightness)
setprop persist.sys.overlay.devinputjack true
Click to expand...
Click to collapse
You're done! Brightness should be fine, headphones get detected, enjoy!
Spoiler: Resetting your phone
Backup all the data you might have on your phone to restore it after the manipulation!
Step 1
Download the fastboot ROM corresponding to your region here.
(The same one used to grab the boot.img and vbmeta.img when rooting)
And extract it.
Step 2
Download the latest MiFlashTool.
And extract it.
Step 3
Put your device in fastboot mode.
(Power + Vol Down, refer to the rooting tutorial for a more info)
And connect it to your computer via USB.
Step 4
Open MiFlashTool (XiaoMiFlash.exe), your device should appear in the list.
Step 5
Click the Select button in the top left,
And point to your fastboot ROM's folder
(The one containing the "AP", "BP", "BP_IN", "images" folders and a bunch of files)
Step 6
At the bottom right of the software, choose if you either want to just:
clean all
(wipe and re-install)
OR
clean all and lock
(wipe, reinstall and re-lock your bootloader)
Note: If you re-lock your bootloader but wish to unlock it again later, you won't have to wait the 7 days again.
Step 7
Finally, in the top right, click the flash button.
Now just wait a while, your phone will reboot on the stock rom and you're good to go!

Hi,
I am also a user of RN9 Merlin.
I think we should add more details like
-how to flash official firmware(both from stock recovery, fastboot)
-should we need the same MIUI firmware that is there before we started booting custom ROM(GSI), if we need to go back to stock?
-what should happen if we interrupt the process in middle
-unlocking bootloader linux, macos or a link for the guide
-why we need to flash vbmeta.img?
-how to make vbmeta.img on our own(some are giving modified one, what is it?)
I know we need more and more time to do these, but these will help a newbie/noob/beginner for Xiaomi and rooting.
Thanks

1.Flashing official firmware is universal method for all devices through fastboot, And for recovery, we can't flash it yet since TWRP doesn't support dynamic partition yet.
2.No, you don't need the same firmware.
3.If you interrupt the process in between, the device would remain in fastboot Mode, and you can still restart the process.

I heard a term called "Anti Roll Back" from https://forum.xda-developers.com/redmi-note-5-pro/how-to/faq-questions-answered-t3816185
Are all our merlin ROMs have same version of anti roll back. That is are we able to flash MIUI 11 on MIUI 12?
Thanks

Anti-rollback is only an issue if you're trying to downgrade through the stock recovery (Vol + Up) or through MIUI's recovery (About Phone > MIUI Version > Three dots and there is an option there)
If you want to go back to MIUI 11 for some reason, you can, by flashing it through fastboot.

1 - Google, this isn't Merlin specific.
2 - No, you can go back directly to the latest MIUI for your device.
3 - Just start over, your device will remain in fastboot, it's actually really safe.
4 - That's a niche demand, 99% of people use Windows and, if you use something else it's on you. If you're a Linux user, you're used googling information and it's not a problem. And for mac, well, worst case scenario use someone else's pc for 10 minutes.
5 - To prevent boot-loops. If you don't flash vbmeta, it won't boot.
6 - Read disclaimers, the tutorial literally tells you to take the vbmeta from the official rom. There's no such thing as a modified vbmeta, what matters is how we flash it with fastboot, disabling verifications.
Also this is my first post, and I'll add more as time goes on. But even as it is, I think it's miles better than what people care to create for most devices on XDA. It's also pretty detailed with images and such to reassure the user.

can someone help me?
So I wanted to unlock the bootloader
Did the
Turnn on OEM unlocking
Turn on USB debugging
Added my device on my account (the other thing to do in developer setting)
Boot into fastboot
The Mi unlock can't detect my device although the drivers are fine (I checked it in device manager) and I run it in administrator check the driver again in the software it says it is installed.
What can I do? Did I missed some steps?

I will not support custom recovery's. I highly dislike them, and they're unofficial for Merlin as well.

Thx for the answer

thanks but I solved it by moving the unlock folder to C:

Hey man. First of all I appreciate that you spent this much time for redmi note 9 users. I just want to know that how do I know that my device is merlin?

Hey, no problem!
Well, Merlin is just the codename for Redmi Note 9. So if you have a Redmi Note 9, you have a merlin.
BUT, keep in mind the Redmi Note 9 Pro, Pro Max and S are different and have their own section in the forums.

Well, thanks but one more thing, I tried unlocking the bootloader of my phone yesterday. I went into developer options and enabled the following options:
OEM unlocking
USB debugging
I also installed all the drivers needed in my pc and went into fastboot mode in my phone. But Xiaomis mi unlock can't recognise my device. I tried 2 different usb cables but the mi unlock just says, "your phone is not connected" I hope to get a reply from you and you will probably will be able to help me out.

I appreciate you replying to me. But, I already fixed it by installing windows 7 I had windows 10 before and it didn't seem to work on it so I installed windows 7 and it worked flawlessly. Btw, are you a user that has installed a custom rom? And if yes, then which one and is the performance any better?
Thanks.

Nope I didn't YET, I'm still waiting for the unlock to complete. I did tried treble roms in my other device. It just is basically have the same performance (LOSQ) but I had heating problems in my Samsung device, I expect a normal experience with this ROMs.

[HONOR 6x EMUI 8.X Oreo] Installing EMUI 8.X on Honor 6X EMUI 5.X and RAM extend via SD Card

My problem is that I can't run correctly LineageOS on Honor 6x, and I didn't know how to run it properly, and I still don't know how to do it because I got bootloop, even if I factory reset...
=> For future people who still want to know how I switch Honor 6x on EMUI 5.X to EMUI 8.X, I write just below the full step and problems that I met during this process (But I think there is already some thread that talk about this.
________________________________________________________________________________________________________
Installing EMUI 8.X Oreo from scratch on a Honor 6x running with the EMUI 5.X Nougat
First of all, I have to thanks @Djiban that help me for the first step ✌
So, many Custom ROM/AOSP ROM for Honor 6x required an EMUI 8.X base.
And to update your Honor 6x to EMUI 8.X, you MUST DEBRAND your phone to BLN L22 India version of the OS
1/ Requirements (Search on Google for installation and how to use, or ask in this thread below)
Spoiler: 1/ Requirements
- You can choose between those 2 methods (Advise you to take the Huawei MultiTool):
Have ADB and Fastboot tools on Computer: ||__Minimal ADB__|| (also present with Android Studio, Unity3D with Android build support)
For Unity3D, if you had add the Android Build Support, the adb and fastboot tools should be here : C:\Program Files\Unity\Hub\Editor\20XX.X.X\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools (Replace 20XX.X.X with your version of Unity 3D)
You can ALSO use ||__Huawei MultiTool v8 __||, that get on more an interface(Great Noob Friendly tools).
I advise you to set the 2 tools inside the Windows 10 environment variable to easily use adb and fastboot command on command prompt. Type adb devices on the console tools of your computer, if it's correctly referenced you will see something like the screenshot:​
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
- Unlock the bootloader of your phone ! (you can use ||__DC unlocker__|| to get the bootloader code for 4€, or if someone know to get the number with a simple batch file code ? It would be awesome) (Huawei don't get you anymore the bootloader code, even with the paid service)
To make DC-UNLOCKER detect your phone :​
In your phone Settings -> About Phone -> Press 7 times the Build Number => To unlock Developpers Options; then go to Settings -> Developpers Options => Enable USB debugging
Install HiSuite from Huawei to get all the drivers needed to detect your Huawei/Honor phone on your computer
You have to type in dial pad(the default phone app) *#*#2846579#*#* then go to ProjectMenu -> Background Settings -> USB Ports Settings -> [U]Manufacture Mode[/U]. You have to redo this if you disconnected your phone, because it will set by default the HiSuite Port !
Once you get the code :​
In your phone Settings -> Developpers Options => Enable Unlocking OEM
Connect your phone to your computer and allow the debugging mode, and choose MTP mode(transfert files, not charging only)
With Huawei Multi-Tool, press Quick Actions(top right of the UI) -> Reboot to Fastboot mode (OS-FB) OR
Open the console (search cmd on windows), and type adb reboot bootloader
Open the console (search cmd on windows), and type fasboot oem unlock YOURCODE
If all good, type in the cmd : fastboot reboot
- MUST install TWRP Recovery 3.1.1 (Other versions will not work for EMUI 5.X Android Nougat) :
Use Huawei MultiTool : In Recovery Tab, it will normally propose you the EMUI5 twrp image or the 3.1.x version. Press Flash Recovery_ramdisk (require you to enable/allow USB debugging on your phone)
You can also choose an image from your download (see link below for twrp 3.1.1)
Or with the cmd
Boot into fastboot : adb reboot bootloader
Install TWRP : fastboot flash recovery twrp-3.1.1-0-berlin.img
||__All TWRP version for Honor 6x[berlin]__||
||__twrp-3.1.1-0-berlin.img__||
- Advise you also to make a backup with HiSuite to save your data, and a TWRP backup to recover your system in case.
- To reboot into TWRP Recovery mode, press Volume + and Power buttons. Or use Huawei MultiTool v8 Quick Actions or type into the cmd : adb reboot recovery
2/ Debrand to BLN-L22
Spoiler: 2/ Debrand to BLN-L22
- See if you already got the BLN-L22 or not : Honor6x -> Settings -> About phone -> Build number

(Careful, the 3 links on the firmware finder database may take 1-3 hours to download, they didn't get a good server speed, same as the step 3) And you may need to flash OEMInfo.zip via TWRP !

OKKK after one all day (9:30AM to 10:30PM) I finally get it !!!!!!! THANK YOU for your advice you saved my phone if I can say Djiban A look of my new version phone below, very happy !!! Now I have to find how to get Emui 8.X on my Honor 6.X without broken my phone
I really thought that my phone was broken because I didn't backup my OEM info with the Huawei MultiTool and ended into a bootanimation loop even restoring my phone with TWRP.
______________________________________________________________________________________
For those who is doing this awesome tutorial : https://forum.xda-developers.com/t/...ln-l22-successful-case-noob-friendly.3679402/ I attach here to my message the Huawei MultiTool v7 that I found on this forum too (but can't find the link in my browser history ) :
For this tool, don't connect to internet when you launch it to avoid auto update, you can enable it after the question about proxy or when you see the main menu. The only bad thing that it's not in english, but the screenshot in the tutorial show you what is what
For the OEM info zip, if you get "sbin/su not found" when restauring int the MultiTool , try also to install it with the traditional way in TWRP via the button Install -> Install ZIP
At the step where you have done the dload method with the update.zip, you will be get stuck in the bootanimation or black screen, it says that you have to shutdown the phone and that's a bit complicated with Honor 6x, you can only reboot whatever you done and adb acess from computer is off (don't activate the bootloader, it can reject the new update you just put in the dload folder !!!)
What I have done is going to Huawei eRecovery mode by pressing and maintaining Power button and Volume +, then choose wipe cache then wipe data/factory reset (it will erase all your data that you have on your last system !). By that, the phone will reboot and get you into the EMUI 5.X and the menu too set your phone, and by that you can rename the folder dload-data to dload through computer as mentionned in the tutorial, then SHUTDOWN your phone and redo the dload activation (Volume + and - and power button pressing)
And that's it ! Some tips to avoid future people stuck for hours and panic because nothing is working and the phone seems to be good for bin

Click to collapse
WARNING : Once you update the OEM info of your phone, the Huawei eRecovery won't find update to factory reset the entire firmware ! So if the Huawei eRecovery tell you that the system is broken and you have to reset your phone (can't avoid that if it tells you that I think), after that the bootloader will be locked, then you can't go to TWRP recovery or start the OS.
DON'T PANIC, go into fasboot/bootloader by shutting down your phone(if can't, just reboot and do the following steps before the phone vibrates when reboot !) : Hold AND Keep VOLUME - , then plug the USB cable
Then on your computer, unlock the bootloader as you already done with the command : fastboot oem unlock THEBOOTLOADERCODE (The bootloader code will be the same whatever your firmware version is, it's unique for your phone harware)

Make sure to keep HWOTA8_BLN folder inside HWOTA_BLN_Eng folder
HWOTA_BLN_Eng should be put inside the Tools folder of Huawei Multi-Tool v8
Make sure the path don't contain SPACE such as C:/Program Files
They are new update of the BLN-L22HNC675 (B520)
The newest one is : BLN-L22HNC675CUSTC675D2B520 (8.0.0.520) update on 2018.11.29
Search BLN-L22HNC675CUSTC675D here
You can upload the 3 zip on my pCloud (it's faster): ||__LINK__||
WARNING : On the first boot, wait 3-4 mins. The reboot to the EMUI 8.X can take some times
If after some minutes, nothing happen and you still on the blue Honor bootloop, try to wipe cache AND factory reset the phone via Huawei eRecovery or via TWRP (don't format data, only at the last resort but I think you have to reinstall the firware through HwOTA8 again). Have to be patient, it takes me 6-8 mins to reboot after wiping cache and data at the 2nd attempt.
- After successfully installed EMUI 8.X :
It's possible that you can't access TWRP, you have to reinstall TWRP Recovery through Huawei Multi-Tool (same step at the step 1/ Requirementsabove).
The tool will automaticcaly detect your device and propose you the BLN_TWRP_EMUI8.zip (press Flash Recovery_ramdisk with your phone open in android and allow the debugging connection - see 1/ Requirements for more informations.
Or you can download TWRP 3.2.X-0 (version 3.2.X only ! Other versions may not work, I didn't try it)
With this version, you will encounter some issue with TWRP. You can't wipe chache, or mount/unmount data for example, so some installtion through TWRP may not work, like for OpenGAPPS who maybe can't be installed when you want to try other Custom ROM like LineageOS. If you know how to install OpenKirin(LineageOS) on Honor 6x EMUI 8.X, feel free to share in this thread !
4/ Extend your RAM via SD Card
Spoiler: 4/ Extend your RAM via SD Card
If you succeed all those steps, you may right now see that your device maybe a little buggy, particularly when you open severals android application.
- For me, I used AParted available on the Play Store : ||__LINK__||
- This app require a rooted phone of course : Install Magisk ||__LINK__|| through TWRP Installation (Reboot to TWRP -> Install -> Install ZIP) or use SuperSU propose by Huawei MultiTool button installation
A PDF/Tutorial are available on the app inside, showing you the step to do with screenshot
WARNING : Save your data of your SD card before continue
You may not see big difference by increasing the RAM memory, it will just allow you to open more apps at the same times without crashing or lag
Summary of steps :
Tab CREATE -> press ADD 2 times (or more if you already have some partitions)
Set Part 1 as fat32 and give him his total storage
Set Part 2 as swap and give him his storage (will be for the RAM) (For me, I choose 2Go)
Click APPLY
Go to Tab TOOLS
Select Part 2 - FS: swap
Choose Swap in the drop down menu next to the button Apply
Press Apply
Watch a video (advertising if yo uconnected to internet)
Cancel the installation of AMemoryBoost
Click ON and OK to enable Swap Partition
Now you will saw the current RAM and the Swap memory
I wish my post can be helpful and I wish you can enjoy your new phone !!!

thanks for this excellent and very complete guide. Hop too that @DarkJoker360 AOSP 11 system.img from Huawei P8 Lite forum will work as it did for march and July AOSP 10!!! I'll give i a try next week for sure :

After a succesfull debrand to BLN-L22 with the very fast way, I'm following your guide to step to EMUI 8, first of all thanks for providing files from your pcloud !!

You did use multi tool V8 to update to EMUI 8 ? Can see any signe of that in the guide you did follow . I guess it just replace the adb fastboot command .
All went fine for me, I'm now on very last EMUI 8 stock ROM for BLN-L22! thx
But of course TWRP flash is now an issue:
all TWRP recovery versions I fastbooted flash (3.1.1, 3.2.3, 3.5.0, all for bacon) sent me the same message error in fastboot: "FAILED (remote: partition lentgh get error)" . Apparently not EMUI 8 version .....

Oh nice wonderful !!! Happy it helps
I used the Multi Tools for the 3 step because it contains the adb and fastboot tools. But if you have it with the minimal adb software it will work also.
And if you set the adb folder to the windows 10 variable path system, I think you can put the HwOTA almost anywhere in the computer disk.
Yep indeed the twrp not work properly...
And still all my attempt to upgrade my OS with another method without the 3 zip (update, public, data) is not working

There is a workaround for custom recovery, I'll try it seriously and post back here

A how-to guide of restoring a completely bricked Redmi Note 9​
Hi, In this guide, I will teach you how to fix a hard-bricked Redmi Note 9 (merlin) and bring it back to its original state.
How does a hard-bricked Redmi Note 9 look like? it's stuck in an infinite boot loop showing only the Redmi logo,
Can't access recovery with power+vol down, can't enter fastboot, can't connect it to a computer either.
If this is your phone here's how you can solve it without the need for service.
Following this guide keep in mind that everything would be erased from your phone including custom Recovery or ROM obviously. Also the bootloader would get locked again.
(I mean at this point you either have a useless brick or a working phone, you are choosing).
This is tested by me, and it works as long as you follow the steps carefully and you don't skip anything.
(I did this on Windows 10 btw)
You gonna need to download, Python and the official Xiaomi fastboot image for Redmi Note 9. Also the zip file I'm attaching bellow. the zip file contains the MTK Drivers, SP Flash Tool, and some additional scripts like MI auth bypass etc,
Get thefastboot image from here select your version (I picked the latest global) click download scroll down where it says "type:fastboot" and click "download: full Rom" the file name should look like this "merlin_images....tgz" or "merlin_global_images....tgz", etc, NOT miui_Merlin.zip,
Get python from the official website site, I tested it with 3.9.7 but the latest version should work fine. Now, you have all the necessary files to start.
Let the phone's battery die so the boot looping completely ends. (else you'll get error STATUS_EXT_RAM_EXCEPTION (0xC0050005) when using SP Flash Tool). ( I also tried it with a full battery and still worked so idk for sure how necessary this step is).
Install Python select the "add to PATH" option, you can test if it was installed correctly by opening cmd and writing "python" or "py" it should output the python version.
Extract the attached zip file and the fastboot image each into their folders.
Enter the MTK Driver folder Install the MTK Driver for MTK SP flash tool.MTK_Driver_Auto_Installer_SP_Drivers_20160804.exe, Reboot your computer.
Enter the python folder, run the "install pyusb pyserial json5.bat" when it's done close the terminal.
Enter the driver folder, this folder contains a USB to COM driver for MTK Devices, right-click the "cdc-acm.inf" click install.
Enter the libusb folder, run the libusb-win32-devel-filter-1.2.6.0.exe file, click next,next...install, when it's done it would prompt you to launch "filter installer wizard" click finish, when the wizard shows up, select "Install a device filter" it would show you your connected USB devices,
Get your phone and a USB cable, connect the USB cable to your computer,while holding the volume up button on your phone connect your phone to the computer (Based on community feedback you might need to hold both up and down volume buttons AND power button!) once your phone turns on you would see your phone listed as "MediaTek USB Port" at the libusb filter installer before your phone reboots click at the "MediaTek USB Port" and then click install if you don't do it on time, your phone will get disconnected because of rebooting, try again re-plugging your phone. once you click install, You should get a pop-up message saying "...device filter successfully installed for MediaTek USB port..." click ok and exit, then remove your phone from the computer.
Enter the bypass folder (This folder contains scripts to bypasses the Mi auth) double click the "1ST RUN THIS.bat" when it says "waiting for device" hold volume up and plug your phone into the computer (btw: You can let the button when it's recognized by the script). now most likely it would say "RuntimeError: unexpected output, expected 0xfd got 0xfe", if it does close the script and disconnect your phone, Try the "2ND RUN THIS.bat" when it shows "Waiting for device" hold volume up and connect your phone to the computer, wait till the console recognizes your phone, (At this part it might take few tries to make it work, try reconnecting your phone without holding any buttons or try holding volume down while reconnecting your phone) Once it gets recognized it would output "Found port = COM3" and Protection disabled. At this part your phone has stopped boot looping which is good but, DO NOT TOUCH YOUR PHONE, DO NOT DISCONNECT IT FROM THE COMPUTER, set your phone aside, and continue with the guide.
Enter the SP Flash Tool folder run the flash_tool.exe at the Download-Agent click choose and select the DA_6765_6785_6768_6873_6885_6853.bin file which is included in the SP flash tool folder.
At the Authentication File, click choose and select the auth_sv5.auth included in the SP flash tool folder.
At the Scatter-loading File, click choose, go to the fastboot image extraction folder (Step 4) then enter the images folder and select the MT6768_Android_scatter.txt file (Fastbootimage/images/MT6768_Android_scatter.txt)
On the drop-downbox below the "Authentication File" label change the option from Download Only to Firmware Upgrade.
At the toolbar above click Options -> Option... go to Connection check the UART option and set the Baud rate to 921600, make sure the com port option is set to com 3, then close the window.
Click Download with the green arrow, now wait till it finished flashing your phone this would take quite of time, at this part DO NOT TOUCH ANYTHING LET IT FINISH TO AVOID ANY CURROPTION ON YOUR PHONE. (If you get "Error : STATUS_STOR_LIFE_EXHAUST" go to options-> general and uncheck Storage life cycle check).
When it's done it would show you a pop-up window "Download Ok" with a green background and a checkmark, click the X to close, and now you can also close the SP Flash tool app.
Disconnect your device from your computer and press the power buttonto start your phone, connect it to a charger or back to the computer since there was no charge so it won't die suddenly now.
Your phone now should boot normally showing the MIUI logo, because its first boot it would take few minutes for the phone to boot, wait patiently and you would see the "first setup" screen.
That's it! You successfully brought back to life a hard-bricked Redmi Note 9 (merlin). A huge weight now has lifted from you hf.

If you did step 9 it should recognize it, try to reboot your computer if you didn't already. Also your phone would be visible only for a second before it gets disconnected so you have to act fast.

Your window is 32 or 64 bit, I use windows 10 64 bit and did all step, one by one but no effect.

Finally, done it. I found this:
- Hold both vol up and down when plug in so the device recognize.
- You must choose right fastboot image (origin stock rom), if not devices can't boot in to miui rom cause bootloader locked after sp flash
And at last, thank you very much, you saved my day.

There's no qualcomm version of Redmi Note 9

i made a mistake,when i clicked to download the fastboot at the xiaomi site,i clicked the fastboot link to download,but i didnt see that it brings you to a page where it has all the downloads again,so i stopped the operation and restarted it with the correct scatter this time.
Now im waiting to see what will happen,how long does it usually take for the spflash to finish?
Also at the bottom of spflash where it says 0b/s,emmc etc. should it stay at 0 when you start the download?
edit:
managed to make it work,one important thing for me was at the option/option,had to select com port com 3

Thanks i updated the guide including this

i'm having an ERROR notification : STATUS_EXT_RAM_EXCEPTION (0xC0050005) help me

Looking for some info/help if possible: apologies i'm not trying to derail your thread.
I had bricked my RN9 but managed to unbrick and have it working ok now however I am wanting to restore it/lock the bootloader to allow for using banking apps. But I am encountering an issue. I had tried using MiFlash Tool but during the flash, I get a mismatch error and it doesn't succeed in flashing the Fastboot rom.
If i was to follow your guide from step 13, would this work for me? Or which steps do I need to skip in your list?
Thank you for any advice/help

Disconnect your device from your computer and press the power button to start your phone, connect it to a charger or back to the computer since there was no charge so it won't die suddenly now.
Your phone now should boot normally showing the MIUI logo, because its first boot it would take few minutes for the phone to boot, wait patiently and you would see the "first setup" screen.
That's it! You successfully brought back to life a hard-bricked Redmi Note 9 (merlin). A huge weight now has lifted from you hf.

Hi thanks a lot for your help. I accidentally flashed a redmi 10x miui 11, wanted to downgrade my Redmi 9 from 12.5, bad perfomance, resulting in your hard-bricked version. Flashing last fastboot version doesn't help, do i have a chance to fix it?

Get the fastboot image from here select your version (I picked the latest global) click download scroll down where it says "type:fastboot" and click "download: full Rom" the file name should look like this "merlin_images....tgz" or "merlin_global_images....tgz", etc, NOT miui_Merlin.zip,

Hi and thanks for this detailed guide.
I bricked my merlin trying to root it (long history trying to get TWRP to stick)
I am now in the redmi logo loop and i am trying to follow this with great care.
however in the step above, no matter what I choose in "Yshasalger" page, i end up with a Recovery ROM and the file name contains the miui prefix as opposed to what you clearly state.
see image:
I am asking because i am scared of making more mistakes.
So i guess my question is if someone can check it happens to them (maybe the page changed since the writting of this guide)
If i should try with that ROM zip file or if there is another place i can get the proper one
I want to if possible to flash an older MIUI / Android than the latest 12 xxx / Android 11 as i find the phone to be really slow since the last OTA update.

That's because you are choosing recovery and not fastboot, choose fastboot as type scroll down it has two links for recovery and for fastboot image. Check the file name

i promise i am choosing fastboot but it ends up in the recovery i have tried several different versions in case it was a file wrongly indexed.

TL|DR
Python errors, step 8 and 12 on Windows 10
Go to -> "start" and type "Manage App Execution Aliases". Go to it and turn off "Python"
=========================
Now read....
Just in case someone has trouble with step: 8
Escenario: the BAT file calls `python` and in some windows 10 this will result in a message about the windows store (Even if the path is added)
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings
but `py` works, so just edit the BAT file and replace the call for `python` with `py` it will install all the python modules with no errors.
EDIT:
This also affects step: 12
Found a solution here: https://stackoverflow.com/questions...arguments-to-install-from-the-microsoft-store
Go to -> "start" and type "Manage App Execution Aliases". Go to it and turn off "Python"

How To Guide How to flash a stock rom [alioth]

Hello everyone.
The purpose of this guide is to illustrate two methods to flash the stock rom on F3, both with the use of xiaomi flash tool (which for convenience I will call "miflash") and with cmd.​Warnings!​Before starting I would like to make one point clear, every moding operation involves risks that could lead to bootloop, softbrick or hardbrick of your phone, they can be caused by countless circumstances or actions, so you need the utmost attention and scrupulousness in performing certain operations.​What I will describe I have tested it on my F3 and it works, in any case, ​neither I nor the xda forum are responsible for any breakdowns on the phone caused by the operations described below!​Having said that, let's start...
All you need is:​
Bootloader unlocked, using the official tool you find here
Latest version of miflash, which you can download from here;
SDK platform tools, which you can download from here;
Stock fastboot rom, which you can download from here, here or here.
Make a backup of your data because they will be deleted in the process!
Now that you have everything you need, follow the steps:​1) How to flash a stock rom using miflash.​
Unzip miflash to C:\ ; [Only for the first time]​
Unzip SDK platform tools to C:\ ; [Only for the first time]
Unzip the fastboot rom in the miflash folder;
Rename the fastboot rom folder with a shorter name and no spaces like "V12.5.6.0.RKHEUXM";
Disable driver signature enforcement in windows 10; [Only for the first time. It is a temporary option that is reactivated the next time the pc is restarted]
Spoiler: How to disable driver signature
1 - Open settings;
2 - Go to update and security;
3 - In the left column click on restore;
4 - Under advanced restart click on restart now;
The pc will restart in a blue screen, click in sequence:
1. Troubleshoot;
2. Advanced options;
3. Startup Settings;
4. Restart;
5. Press the 7 or F7 key to Disable driver signature.
Now the pc restarts by itself.
Go to the miflash folder in c:\, open it and search for XiaoMiFlash.exe, right click and start as administrator;
Click on the driver button at the top and then install (if a warning message comes out, install anyway); [Only for the first time]
Restart your pc; [Only for the first time]
Go to the miflash folder in c:\, open it and search for XiaoMiFlash.exe, right click and start as administrator;
Click on the select button at the top left and navigate to the fastboot rom folder in the window that opens, then press ok; (If you followed the guide it is located in C:\MiFlash20210226\namethatyougavetotherom);
Click on the clean all option at the bottom right;
Spoiler: Why clean all option
- The clean all option allows you to flash the rom avoiding blocking the bootloader (which I recommend);
- The save user data option allows you to flash the rom without deleting the data (not recommended if you come from custom rom or from stock rom of different regions and does not block the bootloader);
- The clean all and lock option instead at the end of the flash blocks the bootloader which in some cases especially if you flash a rom that is not the original and can lead to a brick of the phone (I do not recommend blocking the bootloader, but if you want to do it make sure you are on the stock rom of the same region your phone was born with).
Now in the phone enable debug USB in developer option;
Spoiler: Developer option
Enable developer option:
- Go to settings;
- Tap on my device;
- Tap on all specifications;
- 7 tap on miui version.
Debug USB:
- Go to settings;
- Other settings;
- Developer options;
- Debug USB.
Restart the phone in fastboot mode and connect it to a rear USB port or in any case to a USB 2.0;
Spoiler: Fastboot mode
Turn the phone off;
Long press of the power key + volume -.
If the phone is recognized by miflash its code appears in the first row of the table otherwise click the refresh button at the top right;
Make sure clean all is selected and click on flash;
The flash lasts several minutes wait without touching anything;
Surely miflash at the end of the flash will give an error because the clean all option is selected and not blocking the bootloader at the end of the process it recognizes it as an error. Do not worry!!! it's normal;
If all went well the phone should restart by itself, (attention! the first start of the phone lasts several minutes stuck on the miui logo, wait until the configuration screen appears.
2) How to flash a stock rom using cmd.​Small premise; You could easily use this method even just by starting the .bat file inside the fastboot rom, but if any problems should occur or at the end of the process the window would close immediately without giving you the time to understand what happened, while if you run the .bat file directly from the prompt (cmd) you have the possibility to check the whole flash process and see if any errors occur because the window will remain open anyway.​
Unzip miflash to C:\ ; [Only the first time to install drivers]​
Unzip SDK platform tools to C:\ ; [Only for the first time]
Unpack the fastboot rom and move all content to C:\platform-tools;
Disable driver signature enforcement in windows 10; [Only for the first time. It is a temporary option that is reactivated the next time the pc is restarted]
Spoiler: How to disable driver signature
1 - Open settings;
2 - Go to update and security;
3 - In the left column click on restore;
4 - Under advanced restart click on restart now;
The pc will restart in a blue screen, click in sequence:
1. Troubleshoot;
2. Advanced options;
3. Startup Settings;
4. Restart;
5. Press the 7 or F7 key to Disable driver signature.
Now the pc restarts by itself.
Go to the miflash folder in c:\, open it and search for XiaoMiFlash.exe, right click and start as administrator; [Only for the first time]
Click on the driver button at the top and then install (if a warning message comes out, install anyway); [Only for the first time]
Restart your pc; [Only for the first time]
Go to the start button with the mouse and click with the right button;
In the menu that will open click on command prompt (administrator) a cmd window will open;
Now in the phone enable debug USB in developer option;
Spoiler: Developer option
Enable developer option:
- Go to settings;
- Tap on my device;
- Tap on all specifications;
- 7 tap on miui version.
Debug USB:
- Go to settings;
- Other settings;
- Developer options;
- Debug USB.
Restart the phone in fastboot mode and connect it to a rear USB port or in any case to a USB 2.0;
Spoiler: Fastboot mode
Turn the phone off;
Long press of the power key + volume -.
Now in the cmd window you are in the path: C:\windows\system32. First we move to the platform tools folder and check if the pc recognizes the phone in fastboot (if you followed the guide it will be in C:\platform-tools) to move to the folder press this command and press enter:
Code:
cd c:\platform-tools
Now check if the pc recognizes the phone in fastboot with this command and press enter (The phone code should appear):
Code:
fastboot devices
If the code appears you can start the .bat file to start the flash, then type this command and press enter:
Code:
flash_all.bat
Spoiler: Why flash_all.bat
- The flash_all.bat allows you to flash the rom avoiding blocking the bootloader (which I recommend);
- The flash_all_except_storage.bat allows you to flash the rom without deleting the data (not recommended if you come from custom rom or from stock rom of different regions and does not block the bootloader);
- The flash_all_lock.bat instead at the end of the flash blocks the bootloader which in some cases especially if you flash a rom that is not the original and can lead to a brick of the phone (I do not recommend blocking the bootloader, but if you want to do it make sure you are on the stock rom of the same region your phone was born with).
The flash lasts several minutes wait without touching anything but you can follow the trend in case there are problems;
If all went well the phone should restart by itself, (attention! the first start of the phone lasts several minutes stuck on the miui logo, wait until the configuration screen appears.
I hope this guide can help you to get back or flash the stock rom.
Happy flash everyone!​

Thanks.

It is not advisable to flash the stock rom with twrp for two simple reasons:
1) For the moment the only two twrp developed are in beta state and it is not certain that they perform this task correctly.
2) Twrp does not do the arb check (Anti RollBack) To find out more, read here:
Xiaomi's Anti-Rollback Protection Explained: How to avoid bricking your phone
All Xiaomi smartphones and tablets will have anti-rollback protection enabled. What is it and how do you avoid bricking your device because of it?
www.xda-developers.com
So using miflash or the executable via cmd is the safest and most reliable way to flash the stock rom.

This is not working with locked bootloader.. any other method with locked bootloader to flash stock rom?

It is true! you need the unlocked bootloader, I read that with this tool you can do it. I have not tried it, I do not guarantee the success of the flash with a locked bootloader and in any case I strongly advise against flashing with a locked bootloader. If any errors occur it is risky and complicated to recover it, it is always better to unlock it.

Hello @RollDload
I have Flashed below Fastboot ROM in Mi11X India using the CMD method and working fine but I am surprised why I didn't get OTA for the next Version - Below Mentioned Update Tracker got from another post - My Bootloader is Unlocked - If I manually Update next version using recovery ROM then Can I flash without data lost? - If possible please let me know the solution
2021-04-20 | Stable Fastboot | V12.5.2.0.RKHCNXM (Currently Avalibale)

Hi, I'm glad it worked fine ...
First try to clear the update application data.
If you don't get the update try the recovery method, you shouldn't lose your data. Do a backup anyway to be sure ...

First of all thanks for the Response
I have already tried clear data of Update app, also login into Mi Account but non of the works
Now I will use the recovery method - will follow the below steps let me correct if I am going to do wrong steps
Download this ROM 2021-05-25 | Stable Recovery | V12.5.3.0.RKHCNXM
Put it into Device -> Choose update package - > will flash
Will take backup for Safety

Hi all!
Trying to flash stock ROM (On Linux, cmd command mode), i get following message: "Missmatching image and device" although my phone is a Poco F3 Alioth :/

Why not try the latest update directly? So there is no more need for the ota.
Remember that "CN" is the Chinese version.
"ID" the Indian version.
"MI" l "EEA" etc the global versions.
Use the one corresponding to the one you already have in use.
Otherwise flash what you would like with miflash but avoid blocking the bootloader.

I don't know, I don't use linux, but try to check the drivers and make sure you use the right rom for your model, there are three versions, china india and global.

Yes...Correct regarding latest flash
let me correct you regarding Version
ID - Indonesia ROM
IN - India ROM
I have changed ROM from India to another for Miui Dialer only but after installation, I found Xiaomi EU ROM much better than any other Region ROM
Chinese ROM - good but lots of bloatware, No Gapps
Xiaomi EU - Excellent Performance, MIUI Dialer with Gapps (you can download only from Xiaomi EU website (EU & EEA) both are different Version

okay so I panicked. lol
I disconnected the phone from pc then I realized it was a dumb move
the phone is still on fastboot though.
So I reconnected the phone to pc and it wont detect. I am worried that if I turned off my phone it will die.
So what I did next was hold power button and volume down trying my luck to get into fastboot again.
And it did boot into fastboot again.
Then using miflash and everything worked now im on stock rom. Thanks!
PS: Im so happy that I am still within Gods grace.

yes, unplugging the phone in the middle of a flash is very dangerous, but luck was on your side. better this way

Guys just wanted to clear a doubt i had
So currently I have a mi11x Indian version running miui 13
So my first question is if I unlock via miunlock and then flash custom ROMs (pixelexperience)
Will I be able to go back to stock rom and relock bootloader if in the future I need to go back to stock or something
Or will it cause a brick.

Please, you don't need to know this but I am disabled, get really low on energy really quick. Trying to solve this is driving me mad!
Mi 11 bought with CN stock.
Unlocked the bootloader, loaded global rom for miui 12, all worked well.
OTA didn't work though.
Updated yesterday to latest global rom. All seems to work except, Google Wallet which used to work great gives me their CTS error.
Nothing actually changed on the phone, it's still just the unlocked phone, stock global rom.
I tried loading an older 12.5 rom and then, did an OTA update to MIUI 13
Still, Google Wallet doesn't want to know.
Was considering flashing again with the stock global rom (I don't want the CN on there) and locking the boot again but, would that even work or, does it have to be the CN stock rom?
All the bypass options for the security are just beyond my mind now sadly.

READ NEXT POST!!! MORE INFO DOWN THERE.
First you need to downgrade to EMUI 9. You can do it by downgrading with HiSuite (Connect phone, setup hisuite, click update and then click "switch to other version").
After you have downgraded, you need unlocked bootloader. If you don't have that, pay 20€ for hcu client and you can unlock it but you need to disassemble your device.
It should look something like this.

After you have unlocked your bootloader, you can install twrp.
1. Go to fastboot mode by turning your device off, holding volume down and connecting usb cable from your computer.
2. Once you are in the fastboot, you need to get a twrp. Huawei P20 only have unofficial twrp that is too old so we won't use that. We will use TWRP from P20 Pro.
3. Go to https://eu.dl.twrp.me/charlotte/ and download the latest file. Move it to adb folder.
4. Open ADB (https://developer.android.com/studio/releases/platform-tools) and type "fastboot devices". If you see your device there, it's fine. If you don't see it there, you need to get drivers. (I won't include them here, find it yourself on google.)
5. Type in "fastboot flash recovery_ramdisk twrp-3.6.2_9-0-charlotte.img". (If you have newer twrp version, change the file name.)
6. Type in "fastboot reboot". Now you have TWRP working!
Problems with TWRP:
Touchscreen is not working so you need to have mouse on OTG (USB-C to USB-A adapter).
Media transfer is also not working so you need to push the files with ADB.
"/sdcard" is encrypted after installing rom so you can't really use it, you will only see some random folder names.
Huawei P20 Limitations.
You can only flash roms up to android 11.
How to install custom rom.
1. Head over to this website: https://sourceforge.net/projects/amber-gsi/files/
2. Choose rom that you like. For example I'll use nusantara-11.
NOTE:
Always choose "arm64, ab"
3. Download rom, extract it from the .xz (use 7-zip). Put the IMG in the ADB folder.
4. Enter the TWRP. (Power off, hold volume up and power button and when you will feel vibration release the power button.)
5. With mouse, confirm modification. Connect your phone to pc. Open adb command prompt.
6. Type "adb devices". If you see your device there, it's fine. If you don't see it there, you need to get drivers. (I won't include them here, find it yourself on google.)
7. Type "adb push <your-rom-name> /data" for example, "adb push Nusantara_v2.5.1-11-arm64-ab-Vanilla-GsiTestProjects.img /data".
8. On your phone, click install and navigate to /data. Click "install zip", it should change to "install image".
9. You should see your rom here. Click on it and flash it as system image.
10. Now you need to format your data! Go to main screen, click WIPE, format data. Type yes and continue.
11. Once it's done, you should have "done." as your last message but it will keep loading. Hard restart your phone (hold power button), wait until "your device has been unlocked" screen and hold volume up for 3 seconds. You should have Erecovery here. Click "wipe/factory reset data". Type yes and click format.
12. Phone should restart to TWRP. Click reboot and click power off. Now turn on your phone.
13. Wait until it boot. It can take some time.
You should have your ROM installed.
How to install GApps?
1. Go to twrp, connect ur phone to pc.
2. Download gapps from here: https://opengapps.org/ (ARM64, android version depends on your rom, variant - nano or pico.)
3. Put the file in the adb, open up adb and type in "adb push <file_name> /tmp".
4. Go to /tmp in twrp, click on the file and install it.
Last notes:
If I missed something, just write in the replies.
Pushing rom to "/data" is due to "/tmp" having only 1.4gb space.
If you need to free up space, remove the rom file. (open up adb, type "adb shell", "cd data", "rm <file_name>".
"/tmp" always removes files after restarting device.

NEW UPDATE
I found a way to root on custom roms.
Flash phhs-superuser-ab.zip in TWRP, reboot back to system and install me.phh.superuser.apk.
Now your root is working.
I found a way to decrypt internal storage.
Install some file manager with root access like ZArchiver or MiXplorer.
Download Huawei_P20_FSTAB.zip and extract it. I included original and edited file.
Copy edited fstab.kirin970 to /vendor/etc. Reboot your device into recovery and format your data like step 10-12 in the original post. Now your storage is decrypted.
I found a way to resize system partition for bigger roms.
In TWRP click WIPE, click Advanced Wipe, select System, click Repair or change file system and then click Resize. Now when you swipe, your system partition should be 5GB.
More news:
P20 Can install android 12 but unfortunately it's really badly optimized and the phone is laggy. I tried 3 A12 roms and all of them were lagging.
Best rom for P20 in my opinion?
DotOS 5 from https://sourceforge.net/projects/amber-gsi/files/.
DotOS 5.2 GAPPS from https://www.droidontime.com/devices/arm64. (Battery life is worse than other roms but you have really nice UI, Unlimited storage in Google Photos. Almost like A12)
I'll tell you more info when I gain more experience.

First you need to downgrade to EMUI 9. You can do it by downgrading with HiSuite (Connect phone, setup hisuite, click update and then click "switch to other version").
After you have downgraded, you need unlocked bootloader. If you don't have that, pay 20€ for hcu client and you can unlock it but you need to disassemble your device.
It should look something like this.

I wonder, if I'm currently running Lineage 15.1 (A8.1) with TWRP, rooted with newest Magisk, could I just install that Nusantra GSI ROM or there will be firmware problem? I have Honor 10 but it's essentially same as P20 minus camera OIS. Does everything work with these GSI ROMs?

Well, if i recall correctly you need Arm64, A-only rom. Not everything works. Media transfer doesn't work, stock camera is bad and i think that's it. I returned back to emui 12 after trying over 20 gsis

I'm currently want to set-up the phone again for a relative of me.
So it's better to run with Emui 12 instead of any GSI rom? I thought if I upgrade to an almost-google-free rom and Android 11 it would be better than just sticking to EMUI 12 with Android 10.
I prefer to get as less google as possible on the phone and no bloatware by Huawei or Google.
Any suggestions?
Also can I install any ROM which is listed for Android 11?

Hey, thanks for response.
I'd recommend Emui 12 because gsis are missing lots of features that this phone offers. But sure, you can use almost any Android 11 Gsi Treble rom. You can run android 12 too but i wouldn't recommend it because it's laggy.

is there any way i can root and install magisk on emui 12 ?
i cant found a way to do it anywhere
