Mate 8 bricked after unroot and return to Stock B320 ? - Mate 8 Q&A, Help & Troubleshooting

Hi,
I was running NXT-L29C432B320 Firmware with TWRP and root on my Mate 8. Due to some display issues I have to send the device to Huawei service now. Before I do that, I wanted to unroot and go back to Stock B320 Firmware with locked Bootloader. Now the Phone doesn't boot any longer. When I start now, I see the Huawei flower for 5 seconds than the screen gets black. Here's what I' ve done:
-Unroot via SuperSu app
-Unfortunately I forgot to wipe and do factory reset
-Flash Stock Recovery from B320 Firmware via fastboot
-Tried to lock Bootloader via Fastboot, but failed
-Flashed Boot.img, System.img from B320 Stock - Device stucked in bootloop for hours
-Flashed stock B320 firmware via Huawei dload method - Bootloader gets locked but phone doesn't boot completely
I still can unlock bootloader via fastboot & unlock code and I'm able to flash files.
What can I do to get the device working again?
Thank you very much in advance for your help.

Flash all image files via fastboot and reboot and wipe and start

...I've flashed the files recovery.img, boot.img, cust.img, system.img already. How can I wipe then at start? Do I need to flash TWRP again? If I flash stock recovery with TWRP, how will I be able to wipe anything?

...fastboot doesn't allow me to wipe anything! If I enter "fastboot wipe userdata", I'll get error message "fastboot error failed (remote command not allowed)!
Is there any solution for this?

Fastboot erase cache
Fastboot reboot
Hold volume-up and power and wipe from recovery

Softbricked Nexus S

Hi, I have unrooted Nexus somehow its not booting up no just shoing google Logo. I can only enter in dast boot mode and bootloader is locked hence can not load a new rom to it. Tried to unlock the loaded but unable to do so. Used most of the tools in the forumn but sill no success. Its still not boots into android
Any help will be appritiated.
Can you enter recovery? Like stock recovery or clockworkmod. You should be able to.
If you have stock recovery navigate to it using bootloader, then to active the menu press both the power button and the volume keys ( sorry I don't know which one). Wipe data and factory reset. Select it. BUT THIS WILL CLEAR ALL DATA.
If you have clockworkmod again boot into it like above and select wipe data factory reset. This will not delete you data.
If you have TWRP you can for the same as clockworkmod. But go to menu "wipe" and select wipe data factory reset.
Hope this helps,

Have you tried Wug's Nexus Toolkit? There's an option in the program for this type of thing. It'll flash full stock on your phone but at least it'll be working again, and from there you can flash CWM and root the phone as usual.
It's in the Nexus S Android Development forum, sorry I can't post links yet since I don't have the 10 posts needs.

I am 101% sure that you are missing something while unlocking either the drivers or the fastboot files.
Otherwise nothing can stop you from unlocking. Finally when you unlock, flash the factory image via fastboot and then proceed again towards rooting and customs. :good:
can u please tell me what method you are using to unlock boot loader?
follow these steps:
fastboot oem unlock
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot flash radio radio.img
fastboot reboot-bootloader
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock

Restore Android Stock's Recovery Mode

Hello! I've tried to root my phone (Moto G XT1541 Europe 1GB) but failed. I got an error when trying to flash the custom recovery. Unfortunately, it has overwritten the stock recovery and it didn't install. So, now I have a phone without recovery and I can't do a factory reset because of that (I think).
So, this is my question: how can I re install the default Android 6.0 recovery mode for my phone?
Also, my phone boots automatically on bootloader mode and I can't re-lock the bootloader because I can't flash anymore either; I got an error because the pre flash validation failed when trying to flash with adb fastboot, but this is minimal issues that doesn't really bother me, but they could be helpful and if someone knows how to get rid of them, I want to know!
I hope someone will help me!

The bootloader cannot be relocked in the Moto G 2015, the best you can do is hide the warning screen. Find the stock image and fastboot flash the recovery from there, or better yet, flash the entire image so you are in a known working state
If you are in Pre-Flash validation, you do not have the correct image for your device... I suggest you post in the "How to flash factory images" thread about returning to stock, if it is possible. You MUST factory default before flashing factory images, if you can't, try 'fastboot erase userdata' and try again.
Flash latest twrp via fastboot and reboot into recovery ,
don't reboot into system,
reboot into recovery manually, then you can enter twrp recovery and can flash supersu 2.62.3.
when you just reboot after flash twrp and reboot system erase custom recovery and save stock recovery, so don't enter fastboot reboot, enter fastboot reboot recovery after flash recovery via pc.
Rename twrp recovery as only twrp in fastboot folder in your pc , not as twrp.img,
But cmd as fastboot flash recovery twrp.img , then no errors ( are you unlocked bootloader ?)

Hey! Thank you! I've been able to flash the TWRP recovery and now I can do a factory reset (and also send sms, which I couldn't do anymore for some reason).
I still have the issue where the bootloader screen appears everytime I turn my phone on, and I still can't re lock my device because I can't flash anything either. I've recovered all of my data, so I think I'm going to stick with that for a moment but maybe I'll try what you said some day.
Again, really thank you for helping me!

Now I understand why my flashing TWRP did not take. I simply rebooted to system and still have stock recovery installed. I was successful booting twrp via fastboot and successfully flashed supersu 2.62.3. Is this step in listed in any faq? I must have missed it.
So after flashing TWRP, do you then power down device prior to manually booting to recovery?

Don't power down, already you are in fastboot mode, you can just enter recovery from that. I forget the reference, but i will search and post.

I get this from twrp official page
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
In our phone press simultaneously volume down + power button to enter recovery.

Can't Boot into Stock ROM.

So recently i wanted to unroot, relock the bootloader and go back to factory condition. I flashed xposed too but i just deleted the app so idk if its still up?!
Unroot worked with supersu.
But then i wanted to relock the bootloader with the "Multi Tool 8".After relocking the bootloader I couldnt boot in my system so i Unlocked it again and booted into android 7!
Sadly i wanted to relock the bootloader so much, that i wiped /vendor and all other things except system and sd card in TWRP.
If i want to boot into system now , i cant. Either with bootloader unlocked or locked.
Only things i can do is going into fastboot mode or access eRecovery.
ADB and Fastboot Commands are working.
I tried to Rollback my device but its not working. What should I do now?
Sorry for my Bad englisch. My main Language is German.

Do I need TWRP recovery for the factory reset? Because in Stock Recovery i cant factory reset.
So I would flash system boot and TWRP instead of original recovery?

But when i want to factory reset it stops by 16%

[BRICKED] Honor 6X boots into Stock Recovery, after flash TWRP

hi, somehow wiped the 'system' through TWRP by mistake while installing Elemental ROM (I was on EMUI8). And since then I am trying to flash TWRP to boot, but I am getting nothing. I had EMUI 8
Tried flashing stock nougat through Multi Tool but no use, it succeeds but does not boot into anything, just the stock recovery whenever I turn it on. (boot.img didn't install while flashing)
Whenever I flash TWRP and try to boot into recovery (Vol-up+power), it would always boot into stock recovery.
Tried booting into eRecovery, but same thing.
Tried command 'fastboot boot RECOVERY-V2.img' but got the problem saying 'command not allowed'
what to do.
[EDIT]: Can't use 'dload' method because I had EMUI 8 and if i try to flash nougat firmware, it will show an error after 5%.

What command are you using to boot into TWRP. Can you access Bootloader. What's the FRP and Phone status. Since you tried to flash Nougat I recommend you try fastboot flash recovery and then any Nougat Compatible TWRP. Yo boot into TWRP after flashing hold Power and Volume Up. If it boots into stock, try factory reset. Either it will boot into TWRP or try to reset. If by some miracle you boot into TWRP don't turn off your phone. Plug it on charging and don't let it Power Off no matter what. After that download Hurupdater and stock Nougat Update files i.e update.zip, update_data_public.zip & uodate_all_hw.zip. Now place these three files as well as Hurupdater in the same folder and transfer them to phone through Micro SD or something. Then go to wipe Format Data and then Advanced Wipe and Mark Dalvik Cache, Cache Data Internal and System. Now flash only the Hurupdater.zip in recovery. Once it completes reboot system and while phone is booting hold Volume up yo enter stock recovery and factory reset. Then format Cache and Reboot. First boot can take up to 10 mins. Don't panic. Good Luck.

Tried Flashing twrp-3.1.1-0-berlin for Honor 6X countless times, no success, still booting into stock recovery.
Try with commands for Oreo as well as Nougat.

the only difference in command i know is while flashing recovery, it's changed to 'flash fastboot recovery_ramdisk' from just 'flash fastboot recovery'
can't use dload method because last firmware is Nougat or Marshmellow I think, but I am updated to EMUI 8, so it will crash after 5%.
Dude. What command are you using to flash recovery. The command is
fastboot flash recovery nameofrecovery.img for Nougat
fastboot flash recovery_ramdisk nameof recovery.img for Oreo.
Try dload of EMUI 5. If you maybe try to flash system through fastboot. You can get system.img but extracting the update.app of main update.zip
is there a tool for flashing from your computer? like Multi Tool or something.
if there is, i might try with that.
the command i am using to flash recovery is : 'fastboot flash recovery_ramdisk RECOVERY-V2.img'
Try flashing system through fastboot. There isn't a flashing tool that I know of
