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. 👍

Forced recovery stuck at 5%

Hey all. I was trying to rollback my P9 to a stock ROM, but it failed and now I am stuck with a bricked P9 (bootloop).
My phone is a European P9 (EVA-L09C432). I have an unlocked bootloader.
- Huawei eRecovery and HiSuite restore does not work.
- I've tried forcing the update using the SRK Tool brick utility, but receive the message "FAILED (remote: sparse flash write failure)" when it's strats writing 'system'.
- My TWRP backup does not work, I had a 7GB backup that installs fine, but the phone is still stuck in a bootloop.
- I can flash EVA-L09C432B378 ROM using the SRK brick utility fine, but the phone is still stuck in a bootloop.
- After I have installed B378 and try to force flash B136 using the dload method, it either gets stuck on the "going into restore mode" or it goes to the "installing package" screen, where it is stuck at 5% until it reboots.
Any suggestions?

try one more time install rollback package by download mode

I've tried. Several times, all day :crying: My process:
Write TWRP from fastboot so I can boot into TWRP and transer UPDATE.app to the dload folder
Reboot into fastboot
Write stock recovery image from fastboot
Boot into recovery mode
Get stuck at 5% on the "Installing update" screen.
I've tried the UPDATE.app or firmware B136 (stock), and UPDATE.app for B378 (Nougat)
Both get stuck at 5%.
I'm stuck at the bootloop

isn't srk tool only for MM?
maybe try extract recovery , boot and system partition from b378 and flash by fastboot , next start flash rollback package by download mode

I noticed when I tried to restore my backup using TWRP it failed at "vendor" (Failed to wipe vendor). I receive this issue at vendor and product.
I tried using fastboot to flash vendor and product manually, I receive these error messages:
"failed: remote command not allowed"
The phone won't allow me to write vendor and product.img... but my bootloader was unlocked?
Is it possible I could have relocked my bootloader? How am I supposed to get the bootloader code for my P9 again :/ It's nearly impossible.

I managed to use the recovery dload method to install a beta version of B378 (build number NRD90M test-keys). Will now try to use the recovery method to roll back to B136 and update back to B378 again.

HELP! cannot dload error at 5% . Debranding problem

Hello, i'm stuck and need your help.
My original rom was VIE-L09ITAC555B360 and I was trying to unbrand with srk. This tool is useless with nougat, and did not work in any step.
I've manually unlocked the bootloader, loaded twrp 3.1.1-1 supporting decryption and nougat, the oeminfo.bin and tried to installo the stock rom VIE-L09C432B373 unsuccessfully.
I tried to run update.zip and update_full_VIE-L09_hw_eu.zip in twrp, but I was stuck on errors. Somewhere I read I was required to wipe system data vendor cache etc... So the data partition is now unencrypted.
After I read about the dload procedure, but it stops at 5%. I've formatted a 16gb sd card from samsung created the dload folder and copied update.app. when i run the procedure with the volume up + volume down + power it starts and stops at 5%. Same result with dload on internal sdcard and without any dload at all. Always stops at 5% with errors.
How can I recover? I tryed to fastboot flash the system.img from update.app but still problems.
Please help!
***edit***
Finaly the dload recovery worked using VIE-L09C432B360 firmware.
Why did it failed with VIE-L09C432B370 and VIE-L09C432B373?

B373 is not approved by Huawei
But now you can get B376 from FF (Works perfect with proxy update)

Yes, now I'm on B376
It's so strange I could not dload directly neither the B370 rom.
I had to downgrade to B181 to get the update menu appear again and after that I've upgraded to B360, B370 and finally to B376

here how to fix it :

Problem with stock rom

Hallo all,
i´ve got some problems with my huawei p9. I have flashed the newest TWRP Custom Recovery (3.1.1.-0) to both recovery partitions (recovery and recovery2), and an open Bootloader.
Now i have tried to install the newest firmware for my Phone (EVA-L09C4321B398). There are 3 Files:
-update.zip
-update_data_full_public.zip
-update_full_EVA-L09_hw_eu
in every guid is written that i have to install the update.zip first. I have tried this and get an error:
https://picload.org/view/daowaddl/screenshot_2018-03-10-08-44-14.png.html
so the update cant be installed.
The next thing i have tried is to install it via "dload" folder. At first i have flashed back the STOCK recovery to recovery. (recovery2 is still TWRP). Then i have copied the UPDATE.APP to the "dload" folder on my SD Card.
Now i have booted in the stock recovery (Vol + and Vol- Pressed) now it starts the update but has also an error:
https://picload.org/view/daowaagw/2m7sv4i.jpg.html
In this case i have tried to download another packet of firmware and another and so on.... every time the same s***.
for every step i have whiped and formated the partitions.
now i´m unable to boot in the system because i cant install a stock firmware. if i try to boot normal the device stocks on boot screen. And i have made no backup of the partitions befor i have tried to istall the firmware.
Here are the Datas of the Phone:
-Device: Huawei P9
-Model: EVA-L09
-Firmware before flash: EVA-L09C432B397
-EMUI_ 5.0.1
-Android version: 7.0
Anyone an idea?

Hi! You might want to try doing what I did when I was trying to update my phone to the latest version. https://forum.xda-developers.com/showpost.php?p=75788148&postcount=13 (For the HWOTA procedure that I was referring to, here's the thread link: https://forum.xda-developers.com/p9/development/eva-nocheck-recovery-flash-unapproved-t3705125).
I can attest to it that it was a clean install. I was able to install updates as well through System Update (I didn't reinstall TWRP after).

Old guides, your method worked for FullOTA-MF-PV builds, but new Huawei builds are no more PV. So wait for OTA, flash HWOTA.zip or use no-check recovery method

I call Huawei Hotline for this issue before. My phone is P9 plus, they told me so far they dont have any system update information about model which is below P10 series version yet. They just ask me waiting for system push message.

Bootloop P9

Hi there guys. Please excuse me for posting this in the QA thread but because I am a new member it wouldn't let me post in the recovery section. I joined XDA just to get some help with my Huawei P9
So I have a Huawei P9 (EVA-L19) and I tried to load a custom rom onto my phone. I was going to load resurrection remix 6 onto my phone but did not get that far.
I got as far as flashing TWRP recovery onto my phone. Once I flashed TWRP recovery I still could not get into TWRP 3.1.1 instead I kept entering eRecovery. So I flashed Recovery2 with TWRP and now my phone is in a boot loop. If I let the phone battery drain completely I can boot the phone. But if I shut down or reboot the phone for any reason while there is power in the battery the phone gets stuck in a boot loop. My Bootloader is unlocked but I can't get the phone into fastboot mode. Even with Volume- and Power key and USB. It just goes straight to "phone can't be trusted page" and then boot loops. Is there a way to fix my phone when I let it run completely flat and then log back into EMUI? I tried factory refresh but it just got stuck on bootloop.
So to summarize.
*My phone gets stuck on a boot loop on all reboot/power on scenarios EXCEPT when starting from a completely drained battery.
*Cannot access fastboot.
*Unlocked bootloader
*Not Rooted
*Rebooting phone gets it stuck in a boot loop.
*How to fix phone either back to EMUI or RR6.0
I would wish to either just get my phone working again on EMUI as a last resort. But ultimately I would like to finish putting on RR6.0 because I was unhappy to hear P9 wouldn't get Oreo updates.

RROS 6.0 must go on Android Oreo / EMUI 8.
You first had to rebrand your phone by HWOTA7 to Chinese Oreo AL10 c00 b535 or b528.
Were you rebrabding and hence needed TWRP, or you were trying to flash RROS 6 (for Oreo) on L19 (on Nougat or even MM) together with TWRP 3.1.1 for Nougat?
Please answer precisely:
- What was the full name and number of your stock build you were starting from (like EVA-L19c432b504 or so, not just "P9 L19")
- Have you already flashed (by Fastboot) RROS 6.0 or your first step was trying to install this TWRP?
- Where did you pick up that TWRP 3.1.1.1?
If you picked directly from TWRP site then this TWRP might not work even for Nougat (EMUI 5.x)
- If you picked proper TWRP from XDA threads, then there is always an important detail described:
Immediately upon flashing TWRP, you must boot into TWRP - otherwise you loose TWRP as if it was never flashed.
You must:
- press and keep pressing Vol+
- type in: fastboot reboot, Enter
- IMMEDIATELY at the moment when phone turns off, disconnect USB
- keep pressing Vol+ until you see it boots to TWRP.
Reasons that you were not able to install TWRP might be:
- wrong TWRP
- you did not follow this 'trick'
- you were flashing proper TWRP for Nougat but your L19 was on MM (EMUI 4.x), or you were flashing it once you already rebranded to Chinese AL10 Oreo, or upon you flashed RROS 6....
There are various possibilities, please precisely describe - it's not why TWRP did not flash but why (after this possible mess) your phone does not boot and how to fix it now

No I did not get as far as flashing RR6.
I downloaded TWRP 3.1.1 openkiren for Eva from TWRP's download page.
I only got as far as attempting to flash TWRP no custom rom was flashed yet.
I could of sworn I HAD EVA-L19C185B405 when I started this process.
However I now have EVA-L19C185B403. Not sure if my phone rolled back somehow. If I try search for updates it says the phone is up to date.
My L19 is on Nougat. It's on EMUI 5.0.3 Android 7.0
I did not rename my phone with any Chinese P9 builds or any tricks like that. Didn't even know you had to do that.
My phone still works provided I don't reboot it. And if I do reboot it, it gets stuck on the bootscreen until it drains completely. Then I plug it in to power and it boots successfully again.

For EMUI 5.x you must use TWRP 3.1.1 from XDA (adapted for Huawei Nougat and its encryption), best the latest build eg from post #1
https://forum.xda-developers.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292
and you must flash it with the trick at rebooting as described in previous answer.
Your TWRP you flashed to Recovery2 (?) is likely not even good for Huawei N (but probably for MM).
You must fix your Recovery2 by flashing back the proper stock Recovery2.
You need to download update.zip corresponding to your c185 build by Firmware Finder (find XDA thread about, there is also PC version), unzip and put update.app to Huawei Update Extractor (find also XDA thread about) to extract your stock Recovery2.
Once you repair, please carefully read HWOTA7 instructions how to rebrand (and upgrade to Chinese Oreo - this is a must if you would like to play with OpenKirin Oreo ROMs, they can not be installed to L19 Nugat builds) - and this required rebranding is far more than 'renaming'

Put to Google eg
XDA Firmware Finder
or
XDA Huawei Update Extractor
For the other two I gave you links.
You will really need to spend your time to read the guides

Ok how do I reflash the recovery2 if I cant get into fastboot mode on my phone. Can I do it from inside EMUI?

There are two ways to boot to Fastboot
1) Power off, connect by USB to PC, press and keep pressing Vol-, press Pow
2) From Android, enable Dev options and ADB, connect by USB and execute: adb reboot-bootloader
You cannot by either way?
For Oreo but also reported for some newest Nougat builds, eRecovery gives you an option to reinstall current firmware.
But if you cannot boot to eRecovery, because you attempted to flash TWRP over Recovery2...
Actually, try to boot to eRecovery: power off, connect by USB to charger, press and keep pressing Vol+, press Pow.
If it boots to TWRP (instead of to eRecovery) you can try:
-flash stock eRecovery to recovery2
- flash (proper, from XDA, link was above) TWRP to recovery
There are other methods: HuRUpdater, HWOTA7, HWOTA as improved variations of nonCheckRecovery, but
- first two require Fastboot to start (they will flash TWRP)
- last two require already installed TWRP
(apparently not applicable to your brick)
In HiSuite, for Oreo (maybe also Nougat, I don't know if it depends on Huawei firmware or newest HiSuite version on the PC), there is an option to upgrade/downgrade.
You can try if you could (re)install some stock firmware that way but I never played with.
For eRecovery and HiSuite (if you would be able to do) it is unclear if (re)installation of stock firmware will succeed (or even further brick your phone - don't know if anybody else had such a brick as yours and tried them).
If none as above, you may try DC Phoenix (15 Euros credit?):
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
I didn't need it but search on XDA, from time to time people report (usually in not highly exposed threads) that they were able to unbrick various Huawei phones (when no other methods worked or they were too lazy to investigate and experiment) - but their on-line instructions are not very detailed and they are not very friendly if contacted for help
