Forced recovery stuck at 5% - Huawei P9 Questions & Answers

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.

L19 Problems during rollback

Hi, first time posting here, forgive me if I'm doing something wrong...
I flashed Nougat beta (L19C432B322), regretted it, and now wanting to go back to EMUI 4.1.1 (before flashing, I was on L19C20B150). Trying to follow the steps for the Huawei official rollback package, but problem is I can't even get the intermediate package (C900B300) to work through dload method... update always fails at 5%.
I am unable to relock my bootloader using the SRK tool. The error I get is "remote: root type is risk".
My phone has never been rooted.
Any help would be greatly appreciated!!
Edit: Tried to flash L19C636B168 full rom using dload method. Now bootloader is locked, but no rom is installed, booting always gives erecovery. Unable to flash any recovery via fastboot.

Need help REMOTE COMMAND NOT ALLOWED (Can't go back to stock)

I have an L19C900B220 origanally C185, I tried changing the cust and got stuck on C900, and I also lost root access for some reason, so I tried to reboot to TWRP but it would just take me back to huawei recovery, so I went on SRK and tried to reflash TWRP and it gave me an error (Remote command not allowed) I tried to relock the bootloader same error, I tried to flash the revcovery.img through adb and got the same error, and I checked that OEM unlock was turned on, any ideas? Also DLOAD method gives me something along the lines of your deivce isn't compatible with this software or something
EDIT: NOW ON TWRP 3.1.0-0 can't mount data or system, can't do a data format either, don't know where to go from here, also lost access to use my phone so need an urgent fix, found out I'm still on NRD90M test-keys firmware
EDIT: Flashed recovery and boot, tried to flash system.img it said it worked in SRK, but my phone would be stuck on the bootloader warning screen
From where did you download your firmware? Use official website to download for right and not corrupted firmware.

I had the same issue, I had to use DC Phoenix to restore mine, which was a total pain

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

P9 Plus not booting after flashing twrp backup

Hi i have this p9 plus vie-l29, i unlocked the bootloader, installed twrp and root, everything worked perfect until i found a backup online and restore it using twrp. Since then, P9 shows "device has failed verification and may not work properly".
I boot to erecovery, but i got this error: "getting package info failed", I tried to flash again twrp from fastboot and resccue mode, but not working because i did a factory reset and cannot activate usb debugging. It still has stock recovery but I only have 3 options, reboot, clear cache and factory data reset.
Can you give me a solution to this please? If i try dload method from sdcard, should work?
UPDATE: So, I tried dload method, did not worked for me. Now phone is in service center, I hope it can be fixed.

[HELP] Stuck at eRecovery. eRecovery download fails. dload fails. adb unauthorized.

Update
Huawei Service center fixed it for free!

What happened
I tried to flash stock EMUI ROM in recovery through HuRUpdater 0.4 but forgot to rename the files to match exactly.
Didn't include custom recovery image when updating with HuRUpdater so now I'm stuck at eRecovery.
What I already tried
adb says its unauthorized so no luck flashing custom recovery.
eRecovery fails to download ROM and recovery through their servers (fails at 5%)
dload fails at 5% when unplugged and stay stucked at 5% when plugged.
Device info
PRA-LX2 C636
Help me unbrick
Does anyone know a way to push an update to the device?
Will funkyHuawei work? Is it my only option?
Does Team MT or DC have a solution for this?
