They found a fix for Nougat bricked phones in N6 thread!

As title says, but we need a working backup. Mine is broken, can someone upload a working one, plz?
This is the howto:
1. Flash a stock image (I used the August stock image MTC20F)
2. Fastboot flash TWRP 3.0.2-0
3. Boot into TWRP
4. Select Wipe -> Advanced Wipe -> Select and repair each partition individually (some won't be able to, and that's fine, just move on to the next one)
5. Restore a full nandroid backup (make sure everything is selected) and reboot
6. You should now be free of the never ending boots, and if your device is bootlooped at this point (stuck at the boot animation), you can just flash stock again.

Thanks for this solution. But I have a problem because after installing the rom file .tot have a locked bootloader, and at this moment I can not do flash twrp.
In order to unlock the bootloader command "fastboot oem unlock" I get the answer that it is not possible. NTR it can not unlock it.
Goes some way to upload twrp with a locked bootloader or a way to unlock?

My bootloader is locked, too. The only way to write to the phone seems to be via download mode, but flashing LGH790AT-00-V10f-NXS-XXX-OCT-03-2015-32G-MDA89E-US.tot doesn't work...

To install twrp we need to unlock the bootloader.
However, when the command "fastboot oem unlock" system gives the answer
FAILED (remote: oem unlock is not allowed)
Then how to unlock?

There's really nothing you can do to force an unlock. If you can adb sideload a full OTA zip (say for 7.0) from Google and get that to boot up, that's pretty much your best bet.

I mean, the new unlock command is:
fastboot flashing unlock

On Nexus 5X both commands can be used (oem unlock and flashing unlock)

I followed all the steps except I can't boot to recovery...when I try (manually via ADB or automatically using Wug's tool) it just goes back into the bootloop. I can't even boot temporarily to recovery (without flashing). I'm getting close to throwing in the towel...

Did not work for me, sadly
Edit: Here's how I managed to fix the problem
1. Moved Nandroid backup to PC.
2. Download factory image MTC20F from https://developers.google.com/android/nexus/images.
3. Install factory image (This will erase all data on your phone so move your files to your PC).
4. Install TWRP 3.0.2-0 from https://dl.twrp.me/bullhead/twrp-3.0...lhead.img.html via fastboot.
5. Go in TWRP>Wipe>Advanced Wipe and repair all partitions that can be repaired (System, Data, Cache).
6. Restore Nandroid backup.
7. Success.
Hope it works for other people too, cheers

Anyone in Portland Oregon and want to take a crack at unbricking my 5x? LG gave me an RMA, but given it's not a hardware issue, I'm thinking it will be a waste of time to send it in -- I'm worried they'll just say "all your hardware is fine". Happy to buy drinks or pay a bit if someone can get me up and running.

Zenfone2 stuck at bootloader!

Hello all,
I have Zenfone 2 on which I intended to use a custom ROM.
So the first thing was to unlock the bootloader.
On previous occasion, on my Nexus, I had used the - fastboot oem unlock - command and it had worked. So with that in mind, I booted into the bootloader and tried the command, but it failed - saying oem command unrecognized.
Then I searched online and apparently, to unlock the bootloader, Asus has launched an app! But to be able to install the app, I need to get a normal boot happening, which is not happening now.
In between all this, I tried the commands - fastboot flash recovery <recovery.img>, fastboot flash boot <boot.img> too. But none of these were successful, and each of them returned a 'Permission denied' message, probably coz the bootloader was locked.
Now the situation is that -
- Bootloader is locked.
- Phone is stuck in bootloader
- There is no recovery installed. In fact, from the bootloader, when I try to boot into 'Recovery Mode', it goes there for a second and returns back to the bootloader. Doesn't show the normal android image with a 'X' on top.
- There is no root access.
Now I think the first step is to get root access, and for this I want to try the method with installing CWM recovery and SuperSu.
But for this, I need to be able to push the SuperSu.zip to the phone, which I am not able to.
Can somebody please help!

r the drivers for fastboot & adb update to date?
Android version?

If the phone is stuck in bootloader, you can use Asus Flash Tool to flash .raw files and unbrick the phone.
Raw files: https://yadi.sk/d/FijRoAVJtvRiG
AFT: https://yadi.sk/d/NQCiY--IsQjBr (I use AsusFlashToolInstaller1.0.0.14.exe).

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 .

should I be on the latest version of Miui...12.5 android 11? for me to be able to install twrp. i downgraded back to Miui 12.0.8.0 android 10 as i didnt like my data folder been blocked in android folder. My device is global cannong redmi 9T 5g with diminsity 800u soc, can you please help if you can. thanks in advance

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)

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).

Relock bootloader on LOS microG

Hello all
I desperately try to relock my bootloader but failed many times and I am shortly before giving up. I was once on a locked bootloader on LOS but camera didn't work. (Couldn't reproduce)
Maybe you see something I missed out / didn't understand.
The main reason is, that some apps like ebanking check the state of the bootloader. And they also don't go through Securenet because of huawei.
So what I tried with this setup:
sign both boot.img and twrp.img with BootSignature.jar using own private key
Twrp Using: twrp-3.5.2_9-0-oneplus3
boot img from:
lineage-17.1-20210330-microG-oneplus3
lineage-18.1-20210403-microG-oneplus3
With firmware: oxygenos-9.0.6-firmware-3 from https://github.com/nvertigo/firmware-3t/tree/master/archive/op3
Mostly I got the ideas from https://forum.xda-developers.com/t/device-forum-rules-please-read-before-posting.3333345/
And what I do is this:
Using fastboot flash signed recovery
boot into recovery
whipe everything (is this needed every time?), data, factory reset, all partitions except internal & usb
reboot into recovery
sideload lineageos with signed boot.img inside
fastboot oem unlock => directly restarts after 'yes'
boot into LOS
fastboot oem unlock => directly restarts after 'yes' again
Do you see something I do wrong? Should I use other versions/files?
Hope to find a way
Edit: Also I can go back to stock where it gets locked again using the latest OnePlus3_16_A.86_191104_repack.

The other thing that bothers me is that if you have Google Assistant enabled, it breaks voice dictation. So you can't voice text if you want Google Assistant enabled. So sad!

But I came across this guide from Mr.PvT https://forum.xda-developers.com/t/root-red-magic-8-pro-v3-18.4556901/
He mentioned "Note: Absolutely do not patch the boot file, you will have a continuous boot error"
I am no expert in this, but will patching the boot.img by Magisk causing the situation Mr.PvT mentioned above?

Hi
Fingerprint not work with root? Any solution?
Then which is the command to relock the phone? Uninstalled root and.....

It's pretty easy to root the phone, but it's a more finicky to keep lock screen and finger print functionality. This root guide is more comprehensive and if you read the whole thread you will have success.
What worked for me: Working lockscreen after unlocking + rooting
Just got my set today and started tinkering, managed to get it unlocked and rooted and lockscreen is working (both fingerprint and pin) Here is a summary of what I did, maybe not all steps are needed, but this is what worked for me on the first...
forum.xda-developers.com
Took me a few tries to do it

init_boot is all you need to patch with Magisk to gain root. Just flash it to the active slot. If you dont know your current slot:
fastboot getvar current-slot

Based on experience, you just have to run the command:
fastboot flash init_boot <patched_file>.img
It will automatically be flashed on the current active slot.
