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 me unbrick my P9 and get back to stock (marshmellow android 6.0 FW) please

So i was wanting to upgrade my P9 EVA-L09 phone to Nougat 7.0 i followed guides on here to unlock the bootloader, install TWRP and root the device which went fine. I then got the 2 Nougat FW files from here http://www.stechguide.com/download-huawei-p9-b380-nougat-update-2/ and used TWRP to install the first file 'update.zip' which flashed fine but i didnt realise i needed to also flash the 'update_data_full_EVA-L09_ee_gb.zip' file before rebooting the phone, so after the first file was flash i rebooted the phone from TRWP the phone booted fine but i notice some apps etc were missing. So i tried to boot the phone into TWRP again to flash the 'update_data_full_EVA-L09_ee_gb.zip' file but im was unable to get TWRP to load and all it would load was the Huawei eRecovery app.
So i then decied to try and get back to stock FW buy getting the Marshmellow FW (android 6.0) and using the Volume up + down and power method to force the FW flash, that said it flash successfully but now im stuck on a 'this system is rebooting' loop screen.
Fastboot screen is still saying the phone is 'Unlocked' but FRP is 'Locked'. What do i need to do to get this phone working again please?, is there a recovery FW i can force flash via the Volume Up + Down + Power button method??

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

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.

[SOLVED] EMUI 9 + Magisk, but no fastboot and erecovery factory reset does nothing

Got official notification and have installed Pie (9.0.1.163) on my VTR-L09C432 P10.
Downloaded the Full OTA (9.0.1.163), extracted the RECOVERY_RAMDIS.img, patched with Magisk 7.1.1 and flashed using fastboot to the recovery_ramdisk partition. When rebooted with Vol+ have root. Played around with Pie and have decided to revert back to Oreo.
HiSuite (v9.0.3.300_OVE) did offer me rollback to 8.0.0.365. So I have decided to pursue this option. The firmware download went OK (100%), the programing went OK (100%) and the phone rebooted, as said the popup, but ... it was still on Pie as before.
Decided to try to "upgrade" via eRecovery. It wasn't able to determine and download any package. So I tried factory reset. No error, but it seems to do nothing. The phone rebooted and the situation is: Pie works, Magisk reports root 18.1 and root apps work.
From this moment I am unable to enter fastboot. The phone just boots normally with Magisk root. As I have just written eRecovery is present but is useless (can't download an upgrade package and can'r factory reset).
Advice?
Should I try writing from a term using dd the extracted RECOVERY_RANDISK.img and ERECOVERY_RAMDISK.img ? This way will loose root (Magisk) but don't know if it "resolve" access to fastboot and "fix" eRecovery.
EDIT:
No reply so decided to go ahead with what I thought was happening. I didn't know that a firmware upgrade (or downgrade) needs recovery to complete. I thought erecovery was the key.
So when I used HiSuite to rollback to Oreo what happened was it downloaded the Oreo firmware, uploaded it to the phone, prepared for a firmware flash and did a reboot. The firmware downgrade was supposed to happen in recovery but since the recovery code was changed by Magisk the flashing was never happening.
The same when from erecovery I tried to do a factory reset. Seems that erecovery just prepares things but recovery code does the actual reset. And once again I was observing that nothing was happening. The phone was simply root booting exactly as the Magisk code is supposed to do.
So I just flashed (from a term) the original recovery_ramdisk.img. After reboot got the factory reset welcome screen.
Of course got back fastboot.
Hope this can be of of help someone is a similar situation

Dude can you please guide us how to actually use DD command.
edit: I did this a different way. much easier & safer for less experienced users.
1. Open magisk manager. At the bottom of the first screen there is a button "UNINSTALL". Press uninstall & click "restore images".
2. Magisk will remove itself and restore your original boot image. Worked for me
