[Completed] [Fixed]Bricked Huawei P8

I was running a lollipop bootloader and since i wanted to upgrade to marshmallow i had to update the bloodloader too, so i flashed a new stock boot.img obtained from a stock rom and soon after that i also flashed twrp, i think i somehow bypassed the new (locked?) bootloader with a custom recovery and now i'm stuck in "Rescue Mode".
Device is now stuck into that mode, i cannot turn it off or enter recovery, as soon as i restart my phone it goes into rescue mode, i have already tried all key combinations and also tried to force install from sdcard, my computer is not recognizing my device either so i can't use adb, i had no idea bricking a device like this was even possible, i'm quite desperate.. please help.
[How i fixed it] I somehow managed to get out of Rescue Mode, what i did wrong was not holding vol down + power long enough, you have to hold them down until phone restarts, that takes about 10 seconds, after that you will feel a vibration and huawei logo will appear, keep holding buttons down for 4-5 more seconds before taking your fingers off, it should then go into fastboot, once you're there adb should work and you will be able to unlock the bootloader if it is not unlocked already, after that you should be able push data to device or flash recovery again. If adb still doesn't work check usb drivers, your best bet is probably downloading HiSuite.

Awesome! :good:
Glad you got it going! I'll close this thread now! But here is your device section for future use, http://forum.xda-developers.com/t/huawei-p8
Cheers!

Did I kill my Mate 8?

After failed attempt to get to B211 and B563 from NXT-L29C636B330, I ended up in an erecovery bootloop. I used DC Phoenix to flash an image, tried to update, and now dead. Like won't even turn on or indicate charging dead. No key combination for any length of time does anything.
Is there hope??
I called repair shops...they indicate they cannot help. I bought an international version and am in Canada, so don't have access to Huawei service centres either...
Thanks
Dan

Hi, i am in the same trouble, anybody knows if the Jig solution works? I only need to bring into fastboot again .
Thanks in advance

Sorry to hear that about your phone.
This is the thread to unbrick the phone https://forum.xda-developers.com/showpost.php?p=66776218&postcount=2
But you mentioned no key combination is working.
Is this your model number ? NXT-L29C636B330
Before it was unresponsive, do you remember how much charge it had?
Just to be sure, charge it for an hour or so and then start troubleshooting again. ( I had similar issue, so I left my phone in charging for a while and it worked )
If it switches on.
Check if it is able to go to bootloader mode. (press volume down and hold for 3 seconds and then connect to laptop/computer)
Check if you are able to do dload method ( 3 fingers rule )
Check if you are able to go to recovery ( volume + power -> should take you to TWRP or Stock recovery )
If any of the above steps work, then we can get it back. Don't give up.
Lets hope for the best. Something will work out. :good::good::good::good::good::good:

P30 blocked at boot - How to access User data?

Hi all,
I need your help.
I've got in my hands a P30 (of a friend) that got stuck at boot last week. According to him the device just switched off and would refuse to boot correctly afterwards. Now the device has no physical damage and he could get the main board replaced under warranty but he has a lot of unsaved pictures on the device that he really wants to recover (even if that means voiding the warranty).
When powering on the device, first i get the "The device has loaded a different operating system" screen, followed by the "ERROR MODE" screen with :
Func NO : 13 (recovery image)
Error NO : 2 (boot failed in recoveryboot mode)
I can neither get into recovery nor e-recovery mode; all attempts end up at the ERROR MODE page.
The ONLY thing I was able to get working is fastboot mode. I this mode I go get fastboot to work from a PC and access the device. Hi-Suite however does not "find" the device.
Now as the device is not OEM unlocked, i presume that there is not much I can do in fastboot, right?
My friend would even be willing to send the device to a specialised lab (if that exists, for now I couldn't find any) but I am not sure if that would help anyway; I presume that the userdata partition is encrypted.
Any help / suggestions would be highly appreciated, again the main target being to recover the pics and videos from the device.
Thanks a lot.

Hi m8,
First of all, check for an recovery firmware through eRecovery. In order to do that, check my SS bellow (available on EMUI 9.1). Do as it says and let it download + install (if it's entering).
Second, if he has loaded EMUI 10, in order to enter eRecovery, Power OFF your device or Restart it. Then press simultaneously POWER+VOLUME UP and keep them pressed untill you see Huawei on screen. Release the POWER button and keep pressing VOLUME UP untill you are in eRecovery menu, then release button. When in menu, select Update mode, then select eRecovery mode then Update and recover system then Download update and recover. Connect it to Wi-Fi and it should start the update. At the end, it will restart to system.
Report back your result so i might help you if none of these 2 are working

Hi SilviuO,
thanks for your reply.
Unfortunately, as mentioned in my initial message I don't have access to eRecovery.

When I try to boot into eRecovery I do get the first screen asking to press Vol+ for 3 seconds but after that I again end up on the Error screen.
Thanks anyway.

Use Fastboot in order to find out what version and cust he has. From my experience with other users (from P30 threads and P30 pro threads), if they had EMUI 10 on top of EMUI 9.1 preload and cust, some of them could acces the EMUI 9.1 eRecovery from where they could enter some safe mode called Emergency backup which got them into system and managed to get connected to PC (see my SS bellow) or their Google account and create a backup of their stuffs.
For how to find out his device and info (what he has on it know), please check this link and use the following commands:
fastboot oem get-build-number
and press enter button
This command checks the version, cust and actual firmware of the phone.
If this still not working, i'm affraid that there is nothing else he could do, just have to use a dload firmware in order to revive his device, but by doing it, it will wipe out his data. Even if Huawei Service Centers change his motherboard, they can't recover his data from his actual motherboard...
Let me know his cust and if he is willing to flash a firmware in order to revive it, BUT with data lost, so i can get you a dload firmware for his phone.

Hi SilviuO,
thanks for your help and sorry for the late feedback. Was out of the office these last days and the device was in the office.
Fastboot gives me the following : 9.1.0.168 (C431)
Thanks

Possible or Not? Factory reset bricked Pixel 2.

I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?

I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Thanks for your reply,
Surely Google or some super nerd would know how? But I think I am also out of luck.
Thanks though.

Hi! I don't know if could helps, but did you try to sideload full OTA through recovery mode? This should be go with locked BL too, but I am not sure if you have to have enable usb debuging...

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.
Thanks,
Alex

Did you tried to get to recovery from bootloader screen or with key combination too?

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.
Is this what you're referring to with key combination?

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.

I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.

Samsung Xcover6 unlock bootloader (SM-G736B) before rooting

Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help

It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.

ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?

Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...

Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00

It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.

Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?

The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
