Thank you for your reply.
But these links are taking me to lots of other links and I am confused now. Isn't there a simpler way to achieve these.
Sorry, I am new to these things although once I have installed CM11 to my Xperia GO but it was much simpler.

Atleast try the rooting as in step 1. Those links are just download links.
OK. I'll tell you in short. Download and install these softwares: Minimal ADB and fastboot & AQ 4501Driver
Download this: twrp.img and place it in folder: C:\Program Files\Minimal ADB and Fastboot\
Download this: SuperSu, remove memory card from phone, connect it to PC via card reader and cut & paste this (.zip) file just inside Memory Card and put it back into phone.
Enable USB debugging in phone (Google if u dont know)
Connect phone to PC via USB cable and click on the "Minimal ADB and Fastboot" shortcut in desktop.
Type the following one by one:
Code:
adb devices
adb reboot bootloader
fastboot boot twrp.img
In your phone, wait for few seconds. Click on "Install ZIP". Browse to external_sd and select the file UPDATE-SuperSU-v2.40.zip (which you pasted)
If it asks for confirmation, just do it. That's all! Now reboot phone from there! Your phone is rooted.

Thanks...

Can I install a cwm backup file without unlocking the boot loader ? As an Indonesian android one, android 5.1 cwm backup file is available to download, I'm thinking of installing it myself.

Yes you can. First boot up the CWM recovery from fastboot mode using the command
Code:
fastboot boot recovery_name.img
(I'd recommend Philz Recovery)
First, take a backup of your present ROM from Backup and Restore menu-> Backup to external_SD (so that if things go wrong, you can come back to present ROM)
From now on, you can adopt this procedure: http://youtube.com/watch?v=H4JJu0igXmU
(What the video says is
1. Wipe the system and boot partition
2. Place the extracted Lollipop Nandroid in clockworkmod/backup of memory card from computer using card reader and put it back in phone.
3. Restore this Lollipop Nandroid from recovery.)
Anyway, within a few days, we'll be getting the 5.1 update in India. Why so hurry to see Lollipop??

Lol, no hurry just disgusted by the support of Google and of course can't wait, I bought this phone on a sole purpose of getting fast updates, and did a mistake by choosing this over moto G2. BTW thanks for the reply. I'm trying root for the first time, by your instructions.

Did u enable USB debugging in phone and install phone drivers in computer??
If u r sure about this, try this:
Code:
adb devices
If u see a serial number listed in " Devices connected", then it means ur phone is properly configured for ADB.

Yeah debugging was on and my phone was in fastboot mode. I put the command "adb devices" the reply was "device connected successfully>list of devices connected" and then nothing. When putting the command "adb boot recovery.img" the reply was "waiting for devices" and no nothing happened. Tried this 4 times, did exactly as the video from the XDA root for micromax canvas a1 forum says.

Back to stock after unlock

Hello XDA,
I have a question for you. I'll present the situation first: I bought an EE unlocked Pixel XL, it works perfectly fine with any SIM, BUT it has Andoird 7.1 . It won't let me update it, downloads update (660 MB) and when installing, stops at 10% of the step 1.
Question is, if I flash stock again, will it work with any SIM or it would need unlocking again?
Or how can I update to latest without losing this SIM unlock?

Hello,
Sim unlock should be independent and flashing stock firmware shouldn't sim lock your phone again...
First, enable USB debugging on your phone in developer options...
You can try to sideload the latest 7.1.2 OTA from recovery. Download latest OTA from Google here: https://developers.google.com/android/ota
N2G47E I guess. Plug your phone with USB cord to your computer and simply follow the guide from the link above to apply the OTA...
If that doesn't work either, maybe you should flash factory image
Is your bootloader already unlocked? I heard sim unlocked EE can unlock bootloader. Go in developer option and see if you can toggle "OEM unlock"
If it works, enable "OEM unlock"
Backup all personal data: photos, music, videos, documents from your internal storage. Unlocking bootloader will wipe your phone...
You'll need latest platform-tools including ADB/fastboot:
https://developer.android.com/studio/releases/platform-tools.html
Unzip platform-tools, plug your phone to your computer, reboot to bootloader and open a command prompt in the platform-tools folder (shift + right click on Windows: "open a command prompt here") and type:
fastboot flashing unlock
Check your phone. Use volume rocker to select yes and press power button to unlock the bootloader.
Once your bootloader is unlocked, reboot to bootloader again.
Download latest factory image from Google here: https://developers.google.com/android/images
N2G47E is the latest.
Unzip the folder and navigate inside. Phone plugged to your computer, double click on the flash-all.bat and let it finish. It will reboot.
Your system is now up to date. Enjoy... :good:
Let me know if you encounter any issue.
Good luck...

Hey,
You're welcome
Cheers...

Thank you for the very. very helpful answer. I solved it and here's how.
So, bootloader was unlocked, I tried to lock it again, maybe that was the reason why it won't let me update OTA. After re-locking I couldn't start the phone at all. I powered it on, and got this screen :
YOUR DEVICE IS CORRUPT. IT CAN'T BE TRUSTED AND MAY NOT WORK PROPERLY
Click to expand...
Click to collapse
- the red error
The phone just showed me this screen and was supposed to boot normally after 10 seconds but instead it turned off. The bootloader was locked and couldn't flash anything.
Solution for this problem: just start it in bootloader mode, connect to PC, start a command prompt and type
Code:
Fastboot continue
After this, the phone starts normally, you can enable developer settings and OEM unlocking and also USB debugging.
Now you're ready to flash, just follow @5.1's very good tutorial.

H8P won't power on after attempting EMUI8 Update

Don't know if anyone can help me. I ran the update ending in MF-PV and used DC-unlocker to update from DUK-L09C432B189.
Ended up in a bootloop and tried flashing back to Nougat. Phone continued to bootloop a few times then shutdown and now it won't power on at all.
Tried charging it and it doesn't seem to charge either; that is the LED doesn't come on.
Is there any hope for my Honor 8 Pro???

Try different button combinations, with usb/charging cable connected and disconnected. If the phone still doesn't show any kind of screen then the service center is your final option.

Try flashing with usb and huawei flashing tools

Mixed Nougat/Oreo partitions

My Honor 7x (BND-L21) is totally bricked for the moment. I think there is Nougat and Oreo partitions at the same time because of Huawei Multi-Tool. Now I can't boot into recovery/eRecovery and the device stucks in the splash screen (bootloader unlocked). I think I have to rewrite all the partitions but I don't know how to do it... If anybody has a solution it will be greatly appreciated, I tried for 1 week!

If your device has a locked bootloader or frp follow these steps
First of charge your device for 1 hour in whatever mode it is..
https://www.androidfilehost.com/?fid=11050483647474828964
Then download the service rom from the above link
Extract the contents of the downloaded file. Copy the dload folder from the extracted files to a sdcard.. (Directly to it not on any directory)
Insert the sd card..
Press all the buttons until the emui logo comes.
After the flashing reaches 100 percent.. Reboot the device unlock the oem in developer option..
Step-2 (Computer)
Download adb drivers and fastboot and install them.
Download complete ota package for your device (make sure you have the correct build number because service rom has a different build number ) (download size will be above 2gb)
Extract all downloaded zip files. Then using huawei firmware extractor extract all contents of the update. app files.. (one update. App file in each zip files)
Copy
kernel. Img
Ramdisk. Img
System. Img
Cust. Img
Version. Img
Vendor. Img
And version. Img to the folder having adb files. And version and vendor files to sd card
//Make sure that the complete ota package you downloaded matches the os before the software brick(noughat or oreo) //
Open the adb folder and do shift plus right click to open command window there and connect your device in fastboot mode to pc
Use the below commands one by one each after completion
Fastboot devices(show your device if its connected)
Fastboot oem unlock (code obtained from huawei unlock page)
#factory rest occur
After tha enter fastboot mode again
Step-3
Fastboot flash ramdisk ramdisk.img
Fastboot flash recovery_ramdisk recovery_ramdisk. Img
Fastboot flash system system. Img
Fastboot flash cust cust.img
Flash twrp using
Fastboot flash recovery_ramdisk twrp. img
Boot your device to recovery mode.( Volume up plus power)
Flash version. Img to version partition and vendor. Img to vendor partition
If you want stock recovery back
Boot into fastboot mode
Enter the command
fastboot flash recovery_ramdisk recovery_ramdisk. Img
And do a reboot
Relock bootloader upto your wish..
Better keep oem unlocked in developer options
If you have both unlocked bootloader and frp follow from step 2
I heard huawei discontinued the unlock page
In that case use dc unlocker to find the code
It will cost some money

Thank you I will try this but the dload method didn't worked when I tried 4 days ago...

I can't go into dload update mode (when I hold all the physical buttons the phone restarts and this appears (picture 1) and got stuck on this screen).
Also I don't know why but the phone doesn't charge, when I unplug it after 1h of charge, it shows the critical battery screen (picture 2) and it goes off...
Any help is reaaly appreciated!

Any other ideas?

Though situation, if not charging. Bit to verify, try different cable and charging brick to make sure.

I changed twice the cable and nothing change...

If battery is not charging, then it will not take a flash.
You can maybe try remove back cover and unplug battery, then reconnect see if it will take a charge.
As for your question about resetting with fastboot. You can wipe data, and maybe format system also. But I don't think that will help you.

My friend is asking help. His situation is similar. The phone is honor 6x.
My opinion is that something wrong with boot partition. you can ask some body extract the boot image from another phone. Then run "fastboot flash boot_ramdisk boot.img".
Hope it helps

Thank you for your answer.
This command didn’t work.

Describe problem please
As I recall it is as follows
** Phone working,
** Attempts some backup or restore using multi-tool
** This made phone no longer boot
**Possible that nougat images flashes to Oreo partition tanle (or visa- versa)
**Now no recovery or erecovery will even boot.
**Also phone shuts off with low battery as soon as cable unplugged.
If this is the case, I see no way forward. Because the battery needs to hold something in order for flashing to complete

NO RPMB (how to install TWRP, a new ROM and using Magisk)

Hello, I have sent my phone to warranty and after that I received a phone with NO RPMB and after many frustrations I found (with help of many users and forums) how to workaround this..
To start:
Download boot image from here
Download twrp from the official website
Change the name to boot.img and twrp.img and put it in the platform-tools folder
Open the terminal there
Download your favourite rom
Enter fastboot mode on your phone
!!!!After this you will loose all of your data!!!!
Paste this to the terminal
fastboot oem unlock
(select yes on your phone)
fastboot flash boot boot.img
fastboot flash recovery twrp.img
fastboot format userdata
fastboot format cache
Reboot to recovery (if it doesn't enter at the first time enter download mode again and restart to recovery)
After that you have twrp and can flash every rom.. yay!!!
Wipe everything.
Copy the rom zip to your phone using MTP
Install your fancy new rom
If you want to install magisk:
Install the magisk manager.
On the app select install and select patch image file. (it will create a new boot image already patched)
After that install the new image (patched_boot.img) using twrp
Do a clean instalation of your ROM (recomended) or a Factory Reset first
Reboot to twrp
Select install
Click in install image
Select patched_boot.img
Select install to boot partition
Reboot.
Install magisk manager and do the sugested setup.
You now have magisk working
Thanks to all the users that helped me!!

I had real trouble getting twrp to work the last time I tried this a few months ago. Followed the steps here and am now on pixel experience with magisk. Thanks!

Hello, im in the same situation of NO RPMB. This procedure will permanently lets have bootloader unlocked?
About Magisk, i can install it in usual way once im in the recovery? (I mean download latest stable version for Bullhead and flash via TWRP).
Thanks.

My bootloader is still unlocked after following this guide
For Magisk:
-Install your custom ROM and boot it up (without root)
-Then extract the boot.img from the ROM zip file and save it on your phone storage.
-Install the Magisk manager apk
-In Magisk manager, select install Magisk> choose the patch boot image option and -Select the boot.img you previously saved.
Once it's done, reboot into twrp and flash the patched boot.img. When you reboot Magisk will be working.
I've had no issues with my bootloader, even after an ota update for pixel experience.

Thank you, i will try it.
Another question. I never tried dowload mode before, as i read in other post i should Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb that's already connected to pc, right?
When in download mode i can fire up fastboot commands like im in bootloader mode?
So then after do last command fastboot format cache i can reboot to recovery from terminal using adb reboot recovery or i can / should do it from device?
About twrp it's ok to use the latest 3.2.3.0 official version or the 3.2.1 4core version from here as someone suggested from Reddit? https://forum.xda-developers.com/nexus-5x/development/recovery-twrp-3-2-1-4-core-t3796656

The official twrp works for fine for me, haven't tried the 4 core version but it can't hurt to try if you need it.
Power off your phone then press and hold volume - and power to enter bootloader, then connect to your pc and follow the steps in the OP

So i have to enter in bootloader mode? At point 6 of OP there is written to enter in the download mode, this makes me confusing.
Can anyone explain me latest 2 commands why they are needed?
fastboot format userdata
fastboot format cache

This thread is fairly comprehensive;
https://forum.xda-developers.com/nexus-5x/general/moto-nexus-5x-sticky-roll-t3207487
Holding volume - and power takes you to fastboot mode (download mode essentially), theres also an option to reboot into recovery (selectable using the volume keys.)
Formatting user data and cache is necessary prior to installing a new rom (especially if moving from stock). You lose all data (back up first!) But a clean flash is the best place to start.

Thanks for the explanation but for installing a new ROM usually you can do factory reset directly in TWRP, plus doing all the wipes, this should be enough.
About fastboot mode and download mode, they are completely different, fastboot mode: vol down + power, download mode for LG: Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb.
My question is what i can do in download mode? As OP says after entering download mode open terminal and use fastboot commands.

You need to use vol- and power to go into fastboot mode then connect to the pc. As for userdata and cache, if you don't clean them when coming from stock you will have issues (your data will be encrypted if you're on stock?). As I said this guide worked for me. The op was talking about fastboot mode in the 6th option (also there is much more information in the thread I linked above)

sorry for the confusing i wanted to say fastboot mode..
i knew the thread that you are saying but most people doesn't want to search so I made a little thread only with the needed parts..
I use it myself so I have a place to remember all the steps when I need to change the rom to a new one or when I make experiments and brick my phone XD

If anyone know anything else that should be in here just say, I really want to improve the post

Hi. I just went through the whole process several times (I have tried the different modified boot images from the dedicated post) and my device is still locked [emoji24] any suggestions?

your device will always be locked this is a workaround to get twrp, new roms and magisk while it stays locked..
with twrp usable it won't matter if you are locked or not

Thanks for the answer. You mean that now I have twrp, I can flash custom Roms with my bootloader locked without any issue?

Yes if you have TWRP you can install custom ROMs, custom Kernel's, magisk, super su, etc..
the locked bootloader only prevents you from using fastboot commands like the one needed for installing custom recovery
Now that you have TWRP you can use it for everything

Hello everyone, I also have a nexus 5x with motherboard that has been replaced under warranty and unfortunately I can't keep the bootloader unlocked.
I tried the procedure you have indicated, but at this point there is the problem, because after inserting the boot.img and twrp.img inside the phone, then when I go to do the unlocking procedure with 'fastboot oem unlock (select yes on your phone) 'in practice the memory is deleted on the phone, so I lose the previously uploaded files, and therefore I can no longer continue with the flash procedure of boot.img and twrp.img because they are no longer present in memory.
I hope I made myself understood, maybe I am wrong, or is there a way to solve this problem?

fastboot is for the files on your PC not your phone
you need to put the files inside of platform-tools and then open cmd inside it and use the fastboot commands
fastboot will take the files of your PC

Hello, thank you for your information, since I haven't done modding on phones for a long time, I didn't remember exactly the procedure with fastboot and therefore I didn't understand where I had to put the files, but in the end I did it.
Thank you

Why is a custom boot image needed? I don't want to root.
