Flashed wrong kernel.

I flashed a wrong boot.img in my honor 7x (BND Al-10) using fastboot and since then, even TWRP isn't accessable. I flashed it, thinking the ROM I'm installed doesn't have anything for the boot partition and that's why isn't booting it (Not even showing up the boot animation). I was running on EMUI 8 earlier and shows an exclaimination mark upon trying to access TWRP (With options at the bottom). Fastboot and stock recovery are still accessable. How to revive this thing now? I've tried various methods, but all of them require TWRP.

Follow this post..https://www.google.co.in/amp/s/foru...pment/oreo-twrp-complete-backup-t3764500/amp/
In short
1. Downlod the two files in that post
2. Connec mobile to PC. Enable usb deuging
3. Install ADB in PC.
4. Copy the two twrp files into the adbfolder.
5. Flash twrp img mount and then flash twrp complete backup
fastboot flash recovery_ramdisk file 1
fastboot flash recovery_ramdisk fle 2
6. Reboot
To enter twrp..press power plus volumeup onstartup

I made the mistake of leaving the usb lead plugged in when rebooting to recovery, it will not you into emui Erecovery
If you can get into fastboot it's fixable

Mine is fixed! Just download service ROM for honor 7x. Extract the zip and copy the update.app file ''to your phone's SD Card!'' create a folder named 'dload' and put that file in it.
Shut down your device, remove any sort of USB. Press all three buttons. It'll install the stock EMUI.

Stuck on splash screen "Your device has been unlocked and can't be trusted."

Stuck on splash screen "Your device has been unlocked and can't be trusted."
Hello, first I apologize for my English.
After a factory reset of my Honor 7X ((BND-L21), and a failed flashing of TWRP, my device stuck on "Your device has been unlocked and can't be trusted...Your device is booting now..." at every boot.
I tried to re-flash TWRP recovery through fastboot (PHONE Unlocked, FRP Unlock). At every time the process on the command window works but when I want to boot into TWRP, nothing appears, the device reboot and got stuck on the same splash screen.
I can't boot into eRecovery (I think I deleted it...).
I can't use dload method (I tried but when I hold both volume buttons + power, nothing happens, it reboots into the same screen as usual.
I tried to unbrick the device with Huawei Multi-Tool, the process works but nothing new on the device.
I tried to drain the battery, without results.
If you want any precisions in order to help me, don't hesitate.
Thank you all very much, any help will be really appreciated.

There must be more to the story of what goes on to the device.
You only say factory reset and failed twrp install.
But also say the fastboot screen show successful flash of twrp.
So how did you flash it? What command?
Also say you cannot boot erecovery , think it erased. How, when?
I think maybe you flashed wrong partition, but need your input as to what command you used.

Thank you for your answer.
I flashed TWRP with the command "fastboot flash recovery_ramdisk twrp_7x.img".
Yes, at the beginning I would like to install a custom rom, but it failed so I did a factory reset with twrp. After that I tried to install the original firmware and unbrick the device with Huawei Multi-Tool (by following an other thread).
Everything goes well on Huawei MT screen, but not on the device (bootloop after rebooting).
I tried to force original firmware installation using Fastboot commands (fastboot erase name of partition and fastboot flash name of the partition file.img). I flashed system.img, cust.img, product.img, vendor.img, ramdisk.img.

Oooooh. Sounds like it's possible you have mixed Oreo and nougat partitions somehow
This I have seen before when using multi tool. When not correctly setup
Try from fastboot to get the prop file.
"Fastboot get prop"
I think is correct command.
I will check in my notes, when I can to see.
Interested in seeing what build number is shown if any .
And if possible to get a partition layout, but I don't think you can from fastboot alone.

Thank you but "fastboot get prop" is not the right command. If anybody has a solution it will be awesome.

Download the latest full ota package for your device (around 2gb)
Extract the contents of the update. App using huawei firmware extractor and
Flash
kernel
Ramdisk
Recover ramdisk
System and cust images using fastboot
After that flash the correct version of twrp for your device and then install images of version and vendor(found in update. App file) partitions using twrp.
.
This method worked for me

It didn't worked for me... Do you know any other method?

I tried many TWRP versions but the phone doesn't boot into TWRP...

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?
Envoyé de mon ONEPLUS A3003 en utilisant Tapatalk

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.

Question Rooting - anyone successful?

I've been trying to root my Note 9T. The bootloader has been unlocked, and I've followed a guide from here: https://unofficialtwrp.com/twrp-3-4-2-root-redmi-note-9-5g-cannon/
I'm now stuck in a bootloop.
Anyone been successful?
I additionally tried using a different version of TWRP, which wiped the "misc" partition. Can anyone provide an image dump of the misc partition so I can flash it back on? I can't find a copy of misc in the stock firmware file.
UPDATE 1:
I put the full stock image back on and am back to having a working unrooted phone, so I don't need the misc image. Would really like to get this thing rooted though.
I've installed the Magisk APK, patched the boot image, and flashed it. But this also results in a boot loop. If I flash the stock image back it works again. Any ideas what's going on here?
UPDATE 2:
I got it working! The key was to flash the stock vbmeta.img with fastboot functions to disable it.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Hiya. I've tried that and managed to get to the twrp page. However, when I go to install magisk via twrp, it just reboots into a bootloop. Any ideas?
Update: This seems to have worked.
[SOLVED] Phone gets stuck in bootloop if I try to install Magisk ZIP!
From the forum I followed these step to install magisk: - Patched my boot.img of my current rom using Magisk Manager and flashed via fastboot - After rebooting from fastboot it got stuck in recovery so had to wipe all data and it booted finally...
forum.xda-developers.com

Did you manage to get Magisk working after the reinstall of stock firmware, or you've just resolved the bootloop?

I'm interesting in at least rooting and if possible install TWRP .
Can you post i complete procedure to root the note 9 T ?
Thanks

I can have a go. But I'm not 100% sure what exact steps I took that got it working, as I flashed and re-flashed several times. Give this a try and let me know if it works or not?
WARNING: EXPECT TO LOSE ALL THE DATA ON YOUR PHONE!
Step 1
Obviously you need to unlock the bootloader first: https://en.miui.com/unlock/
If you haven't done this already, after your application it's likely you might have to wait 7 days before Xiaomi actually let you unlock.
Unlocking wipes your data.
Step 2
Start the phone normally. Copy the latest magisk apk (https://github.com/topjohnwu/Magisk/releases) over to the phone and install it.
Step 3
Find the correct original ROM for your device (https://xiaomifirmwareupdater.com/miui/cannong/). You'll need the full image. From the ROM extract the boot.img and vbmeta.img. Copy the boot.img over to your phone.
Step 4
In magisk choose the option to install and select "Select and Patch a File" (should be the only option anyway). Select the boot.img you copied over. This will produce a new file called something like "magisk_patched-22100_XXXXX.img". Copy this file off your phone and onto your computer.
Step 5
Boot your phone to fastboot mode (you should already know how to do this, as you would have had to have done it to unlock your phone in the first place - Hold down Volume Down and the Power button at the same time).
Step 6
Run the following commands (obviously replace the boot image with the correct magisk image, and use the vbmeta.img you took from the ROM):
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash boot magisk_patched-22100_XXXXX.img
Hopefully this will work. But I can't be 100% sure, as the disabling of "verity" could mean that your encrypted user data now can't be read (if you've only just unlocked the bootloader then you're not going to have any data anyway, so not too much of an issue). If this is the case it's likely you'll now need to factory reset the phone. Hold down Volume Up and Power on start to reach the stock recovery menu, and there's a selection for factory reset. You can also install TWRP at this point, and could then use it's factory reset function instead. I downloaded this version of TWRP: https://www.mediafire.com/file/ou8553psro9yyt2/3.4.2_redmi_note_9_5G.rar/file, which came from the other rooting guide (https://unofficialtwrp.com/twrp-3-4-2-root-redmi-note-9-5g-cannon/ - which didn't work). Just flash that version of TWRP to the recovery partition (fastboot flash recovery recovery.img), and ignore all the steps given in the guide it came from.
Let me know how you get on.

sorry for the answer delay.
Adding my 2 cents about unlocking the bootlader .
In order to do it .
FIRST - do not try it from a virtual PC . It does not work (at least it did not work for me)
SECOND , before to run the xiaomi batch_unlock bootlader , don't forget to update google usb drivers
I hard some hard time to just connect the unlocker to my phone . Now i have to wait 167 hours to complete the process .

Android 10 is fine. You need to fastboot flash recovery recovery.img
To boot into it you need to turn the phone off, then hold vol up and power until you feel a buzz, then let go.

I have the same Problem as HighEndGamer:
if I enter 'fastboot flash recovery recovery.img', it sayes that everything worked OK in just a few seconds. But nothing realy happend!
If I enter 'fastboot boot recovery.img', phone boot just as normal.
If I enter 'fastboot oem device-info', it sayes "FAILED (remote: unknown command)'.
If I enter 'fastboot oem lock', it works and I have to start from the beginning..
I have MIUI Global 12.0.2.0{QJEEUMX)

Adding my 2 cents about unlocking the bootlader .
In order to do it .
FIRST - do not try it from a virtual PC . It does not work (at least it did not work for me)
SECOND , before to run the xiaomi batch_unlock bootlader , don't forget to update google usb drivers
I hard some hard time to just connect the unlocker to my phone . Now i have to wait 167 hours to complete the process .

I confirm it does not work from a VM (and the need for latest drivers). There is something funky going on with the USB communication when running from a VM: the first call of the fastboot executable from the windows VM generally works fine, but any other call hang. So the batch_unlock tool cannot work (since it does call fastboot several times).

Recovering data on a DEAD Redmi Note 8 PRO

Hello,
I hope this is the right section for this post.
I've been using a Note 8 Pro with zero issues until one week ago when I accidentally dropped the phone in the water.
After a few seconds submerged the display turned off and I felt an intense heat coming from the zone of the battery.
Having no chance to recover the phone (tried with Isopropyl Alcohol too) I decided to open it and manually dry/clean each component, having seen the situation inside gave me the phone is dead but I still want to recover some pictures/data from it.
Before opening the open Minitool was not detecting any device on my Windows Laptop, after cleaning each component Minitool is instead detecting the phone via USB, but I still can't extract any data because the "Usb debugging" option is not tuned on (and no the device is not rooted).
Is there any option to extract data from the phone? There's a way to turn on USB Debugging via ADB on a non-rooted phone?
Thanks,
Andrea.

how about trying your luck with a service ? most of the time they do have access to special programs, which have a better functionality than adb.

Thanks for the hint, but I am not happy with the idea of someone playing with my data

1. Try reboot phone to recovery
2. Connect it to your computer (download Platform-tools)
3. In the folder with Platform-tools open cmd
4. In cmd - adb shell
5. cd storage/emulated/0
6. ls
7. Now, using the commands, drag files from your phone to your PC

Thanks for your hint.
No luck so far, I think because the phone is not in recovery mode.
I can hear the phone starting up several times (hear the jingle) so I think it's in a reboot loop and I don't know how to boot it into recovery mode wo a working display (tried with power/volume up combination with no luck).
From the windows taskbar I can see that the phone is recognized for a few seconds before it restarts.
EDIT: trying to switch the phone on with the combination "power/volume down" brings to a kind of stable state and I can now see the phone in the windows taskbar recognized as a generic "android device". Still no luck when trying to access the phone as there's no device in windows and no device obtained through "adb devices" command.
EDIT1: I think that the phone is in "FASTBOOT" mode. If I type "fastboot devices" I can see it detected but still can't access it.

Any idea? Should I give up?

If it's popping up and down you need something to keep track.
You can try my UsbLog.exe (in the sig), it just sits there and shows what devices appear (if they have a driver) and disappear.
Try these to see if anything is working:
Code:
C:\>fastboot devices
C:\>fastboot getvar all
C:\>fastboot oem device-info

Yes it's popping up and down when it's booted in recovery mode whilst is stably connected when in fastboot mode but in this case I can't access the internal memory of the device.
I didn't get the purpose of logging the devices connecting to the USB as I can see the device connected for a while and correctly recognized as Redmi Note 8 pro but as it keeps popping out windows have no time to show it's folder.
As for the code you wrote: i will try asap but already tried with "fastboot devices" and I get the phone correctly listed but still can't access its memory as told.

After rebooting the phone in fastboot mode I can see it recognized as a generic android device from windows (still can't access the storage folder of the device).
fastboot devices----> I get the device listed with a series of numbers/letters
fastboot getvar all---> I get a list of information on token/token version/partition type and size/baseband/bootloader etc.
fastboot oem device-info----> FAILED (remote: unknown command)
So I think it's clear that the device is in Fastboot mode and instead is in a boot loop when started in revocery mode.
Is there a way to extract data from fastboot mode?
Thanks,
Andrea.

If you put a custom recovery on it in the first place you can try reflashing recovery from fastboot.
Fastboot doesn't allow you to read anything.
oem device-info is obviously an oem command that might not be on any device.
You've got a Mediatek processor. That has some low level equivalent to Qualcomm EDL, but I have no experience with that.
If you can get there you can download the user data partition, but it's probably encrypted. Also no experience with that.
The easiest is if you can get the system to mount/decrypt the partition.
You've tried the normal system too?
Is this A/B? Have you tried changing slots?
How much time does it stay up in recovery? Do you have ADB? Maybe try:
Code:
# stop recovery
Does that prevent it from looping?

So I should try to flash a custom recovery like TWRP for example?
What you mean with "normal system too"?
Changing slots you mean changing usb port?
It stays in recovery less than one second so I can't give any command via ADB.
EDIT: cant' flash any custom recovery because the bootloader is locked.
If I Try to unlock the bootloader via MiUnlock I get a warning saying that all data will be erased.
Any idea on how to unlock the bootloader wo wiping all the data?

My bootloader is unlocked!
Thank you very much.
Now I am going to try to flash a custom recovery mode via fastboot in order to access the internal memory of the phone.
EDIT: I've just flashed twrp-3.6.2_9-0-begonia.img but still can't boot into recovery mode.
Any hint on how to extract data from the system now?

You really want to boot the normal system because that's the best way to get decrypted data.
I realized that you don't have ADB enabled there.
You should look at B. Kerler's https://github.com/bkerler/mtkclient/
If you can pull the boot image off your device then I might be able to fix it so that you have ADB.
You'd have to flash it back in fastboot or mtkclient.
You can also pull a copy of userdata off the device with mtkclient.
As far as booting into recovery, there's a way.
Here's how, if you don't have A/B (that is you flashed TWRP into recovery and not recovery_a or recovery_b)
then you can fastboot flash a special file into the misc partition and it wil boot into recovery next reboot.
To return things to normal you have to flash the empty file to the misc partition.
Code:
C:\>fastboot flash misc misc-rec.img
C:\>fastboot reboot
Only do this if you don't have partitions that end in _a or _b

I really don't know if I have partitions A and B as you mentioned and I think there's no way to check actually.
I confirm I don't have "USB Debugging" active on the phone.
So if I understand correctly I should do the following:
- Flash misc-reg.img via Fastboot
- Boot into recovery just rebooting the system after flashing the above file;
- use MTKclient to dump userdata or boot image to enable ADB on (I will need help with mtkclient I suppose).
Is it correct?
EDIT: flashed TWRP first and misc-rec then rebooted via Fastboot/Reboot but nothing happens.

TWRP cant boot because you used wrong one. Search again in that unlock bootloader channel and use suitable one.

Hmmm, I am almost sure that the TWRP I've flashed was listed under Redmi Note 8 pro page. Can you please indicate more precisely where should I sera
EDIT: I think I've downloaded and flashed the correct TWRP file.
@Renate can you please detail your method so I can try to extract data from the phone?

1/Yeah it's official. You "flashed correct TWRP." Downgrade to Miui Android 9 (_9 in it's name) to boot into that TWRP and lose your data.
2/In unlock bootloader video above, search other video in his channel playlist and find TWRP video suitable for your Miui version.

Can't find the right video, can you kindly send me a link (I am on the latest Miui version and I am in Europe)?
In all the videos I've seen on his page he is using the device to install TWRP etc.
I think I just need the correct TWRP version for my MIUI release and then I'll flash TWRP and misc-reg.img. Is it right?
