The phone suddenly resets itself

Hi,
I am on rooted P7-L10 C900 B852, for a long time, but recently my phone suddenly resets itself.
When it happens, I have a hard time to turn it on. I have to do it several times, and sometimes I end up with "Optimizing app x of y" message (that is message that is shown after upgrading rom).
After optimizing is completed, my all wireless passwords are cleared so I have to rejoin again.
I tried to do the factory reset from twrp, but with no success – everything is the same as before.
What are my options now?
Can I somehow check hardware (I believe that there are some codes that I can type in for that)?
Could I reinstall B852 again?
How to clear everything and start from very beginning?
Regards.

So now you are at B852 after a automatic reset?
What about restore a backup with twrp?
And what do you mean with twrp factory reset is not working? Is twrp not able to mount the data partition?

If you want to reinstall B852 you have 2 options:
Flash the stock recovery then update using the UPDATE.APP
Get the Huawei Update Extractor tool, extract the UPDATE.APP package and then using fastboot flash the system, boot, cust and cache partitions

I had a really hard time with the phone. Looks like my sd card has gone, so I ordered the new one.
I have downloaded update.app and I have flashed B830 recovery.
Is this anything I need in order to flash stock rom again?
I will use three button restart in order to activate flashing process.
Whatever I do, I want to put phone in factory state.
What is current twrp version that I have to flash in order to root the phone (supersu)?
Regards.

After flashing stock recovery, I used recovery to do factory reset. Than I have put update.app on sd card, and installed B852.
After installation has completed, I have installed twrp from the link above and flashed supersu.
By now, I am using the phone for few days with no problems at all. Even battery has more stamina.
Thanks guys. 👍

NEM L-21 Bootloop

After unlocking my bootloader on my NEM L-21 I installed TWRP too, it all worked fine and well and then I decided to flash a CM13 ROM, before doing that I wiped my cache and userdata, I tried flashing it but then it threw me errors about not being able to mount /cust, I decided to restart it and leave it for later but now after restarting I can't boot into my system.
It restarts by itself if I try booting into the system, booting into the erecovery is useless since it cant find a firmware for my phone to download, and whenever I try booting into TWRP it gets stuck on a screen with "Your device is booting now...".
Any ideas on how to access TWRP or possibly flash the stock rom? Fastboot refuses to do it.

Download the official firmware. Extract it using "huawei update extractor". There u will find recovery. Put ur phone in bootloader mode, by volume - & power button. Flash the recovery. Put the dload folder in ur sdcard. Then by the three button procedure, flash it.

Huawei p9 bricked EVA-l19

Hi, i managed to brick my p9 eva-l19, i was having the stock rom with the latest update, bootloader unlocked, twrp, rooted and i managed to brick him by wiping all. Now all it does is entering in bootloader mode, recovery (twrp) and that's it. I downloaded the stock rom with the latest update, put the update.app on an sdcard but it doesn't work in download mode, the update is not made, error.
What i have to do to unbrick my phone? i'm sure this question has been asked a lot of times but i didn't find a good answer.

When you downloaded the stock rom you got a update.zip and a full_data.zip (or something along these lines). Just Install them via TWRP ( VERY IMPORTANT: first update.zip and then full_data.zip). after that go back and wipe chache and dalvik, then go in the main menu of twrp and klick on reboot and then on recovery. You should boot into stock recovery where you need to wipe cache and do a factory reset. You should boot into stock firmware

EVA-L09 inconsistent state

Hi there!
I have a P9 (EVA-L09) on my desk, which is in an inconsistent state. Meaning, that it in original condition it was a C02 with German Vodafone branding. Then the owner flashed some Nougat beta (can't remember which one), wasn't happy with Nougat and wanted to go back to MM by using the official rollback package provided by Huawei. The dload update failed and then he tried to flash different versions stock roms (can't remember either), leaving it in a constant bootloop. So first thing i tried was flashing TWRP. It boots up, but the touchscreen is not working. I think this is because some of the partitions where destroyed (firmware e.g.). So I flashed the C432B182 recovery and tried to dload the C432B182 firmware. The update process stops at 5%, maybe because in the meantime the device was converted to a C900? So I tried to get some C02 firmwares. The oldest I could get was C02B339. dload started the update process and failed at nearly 100% with the "Software install failed" message - no additional information. Because I have only fastboot and no adb connection, I can't rebrand to C432 (only adb shell in twrp is running, but I can't access the internal memory from there - or can I?). So these are the hard facts and I don't see any way to get a working rom on the P9. So, is there anyone with another idea? Would be great. Thanks!

Ok, I got it working again. Here are my steps, just in case anyone gets in the same situation:
1. Flash Stock recovery through fastboot, extracted from C432B182
2. Boot to Stock recovery with Vol Up + Power, it should start
3. Wipe cache and try to factory reset - won't work
4. Put C432B182 UPDATE.APP in dload folder on SD card
5. Tried Vol Up + Down force flash, but it did'nt work, so I wanted to get back into recovery by starting with VOL Up, and voila - it started flashing the B182 from SD card, BUT says failed at 99%
6. After that, boot into recovery again and see that factory reset now works
7. After factory reset restart phone and enjoy your unbricked P9 on C900B182. From here you can change to C432 with the known manuals to get the latest updates

P10 Bricked after bad TWRP, need help

Hi everyone.
I have a VTR-L09C119 that got bricked after formatting the data partition in TWRP. When I try flashing a debranded FULL-OTA rom I get into a bootloop, and the erecovery won't work (Online recovery won't start, Factory Reset goes into bootloop). And I can't get into TWRP anymore even after flashing it.
I tried putting the VTR-L09C432, VTR-L29C432 and the VTR-L09C605 with the HUAWEI Multi Tool with the Unbrick option, which didn't work.
Any idea how to get out of that mess?
EDIT: Ok I was able to get into TWRP thanks to THIS GUIDE. I'll try a debrand and report back.
I was able to rebrand to VTR-L29C432, the update for VTR-L09C119 doesn't seem available so I don't think I'll be able to get back into my stock rom. For those in the same boat, don't forget to unplug your phone when you want to get into TWRP, that's why I wasn't able to get back into it.
