Rollback to a working rom - Huawei P9 Questions & Answers

I downloaded C432B386 files through HWFF app and I "flashed" them by dload method but now some apps are missing (for example themes, camera ecc..) and bluetooth doesn't work.
Info on my phone:
Model number: EVA-L09
Build number: EVA-L09C432B386
How can I rollback to a working stock rom?
I have locked bootloader and stock recovery.

You need to download rollback package for ur model from huawei site and flash it- dload method, and then find full MM firmware for ur model-dload too, after that u will have OTA update in ur setting, click update there and everything will be good

yes, with dload method. and now i'm want to downgrade to marshmallow again..
Me too. Roolbak erreur
You have to download the rollback package from huawei support, install the update.app from the rollback with the 3 button method, it's around 100mb, or so. Then download the marshmellow firmware, install it with 3 button, then you will have 6.0. You probably won't have the themes, it can be solved with twrp, and flashing the eu (or the region of yours) cust package.
I did that , and now I have c900b170. everything works ok except themes .
if I install EVA-L09C432B136 through dload method, should everything work ok? I will be able to get later the ota nougat update?

Hello everybody, i bricked my phone with the dload method, what the **** please, there are no files which work, everytime, if i try to flash dload method rollback package, or firmware, it says "Incompatibility with the current version"!

After you finish the dload process, boot to EMUI then simply check for updates in settings.

Unlock bootloader, flash twrp and install update.zip and full_update.zip for your device
Or you could try to find the files to update the devices via dload to a other firmware, but I'm not sure that works, because you want to change the cust.

Unable to install stock rom Huawei P9

Hello!
I'm currently running on EMUI 4.1.1 (EVA-L09C900B182)
I downloaded the official firmware for P9 from Huawei website, extracted the UPDATE.APP with this tool https://forum.xda-developers.com/showthread.php?t=2433454 so i could get the stock RECOVERY.img.
I placed the UPDATE.APP in a dload folder on the root of my external SDCARD
Rebooted into bootloader, flashed the stock recovery (I had TWRP).
vol+, vol- and power button togheter, it tries to install but fails (software install failed! Incompatibility with current version. Please download the correct update package.)
I tried also with huawei firmware finder app and even if it says the firmware is approved for the installation when i verify with IMEI, it fails after (I tried EVA-L09C900B386).
I tried:
- with the in-app proxy, changing my wifi proxy to localhost:8080 and using the default updater
- downloading the package and manually moving UPDATE.APP in dload on my ext sd card.
What i would like to obtain is a full stock huawei p9 phone, so i could get the official android 7 and latest firmware.
Thanks a lot!

U have to downgrade to B182 and then upgrade to B360 FullOTA-MF-PV
When u upgrade to a new Android system u must flash FullOTA-MF-PV
U could try without downgrade first, but u cant upgrade to B397 because its not signed yet by Huawei, B395 ist the latest approved Firmware.

From b182 OTAs will lead up to b395.
b397 OTA is expected any day, meanwhile it can be forced (as well as the newer b398) from b395 by using no-check recovery:

Update:
I reinstalled from b136 => b166 => b182
After that i tried b378 but now my build number is NRD90M test-keys
Will start again from b136 trying something different.

Hi! I don't know which version it's fine for your device and the only way to know it it's to flash it yourself, but i don't recommend you to do that.
Rooting with Magisk is fine on 9.1, just read the latest posts from this thread - > https://forum.xda-developers.com/mate-10/how-to/guide-magisk-root-mate-10-pro-t3886967/page27
As for the roll-back, ut should be possible to do it with this tool and an appropriate roll-back firmware (again, firmware version might depend on your cust/brand).
I recommend you to keep an eye and also read this thread - > https://forum.xda-developers.com/mate-10/how-to/firmware-version-mate-10-t3722019

B303 is not for A09, it's for C800 which is some jp cust.
Most new fw links are not up yet, and since Huawei decided to name all their firmware the same regardless of model its hard to know which is which :/

Great! Soon i will upload a new version that will also flash the patched Magisk ramdisk_recovery and Magisk Manager (this one will be optional, so those who already have it, can skip it).
It worked for me also.

Nope! Well, it can be done without root too, but it would require twrp in that case.

as stated before, since every update is named the same it's hard to tell which is L09, L29, A09 or AL/TL. AL/TL are easier as VERSION.mbn in UPDATE.zip doesn't have Global strings in it.
From what it seems, if you flash L09 on L29 or vice versa you get endless OTA updates for preload and cust. I don't know if just flashing the cust and preload zips fixes it, but you're free to try if you want.
Here's L09 preload and cust:
Preload: http://update.hicloud.com:8180/TDS/...full/update_full_preload_BLA-L09_hw_eu_R1.zip
Cust: http://update.hicloud.com:8180/TDS/...4//f1/full/update_full_cust_BLA-L09_hw_eu.zip
modified tool to include preload and cust:
https://mega.nz/#!oDR2DYCI!SRQlTq1IriGcEt1Wr--ggrBk7uZ4M_R8OwE6DdvmEEc
Extract and put in the EMUI 9.0 to 9.1 update folder.
Rename cust zip to update_cust.zip and preload to update_preload.zip, put in ZIPS-HERE folder, run modified bat.
Thank you very much, I try very soon. Have any of you done that already?

I did on L29 with L29 preload and cust, no problems.

Soon i will upload a new tool that will let you flash all the 3 files, so you could wait. Also, a fried of mine is testing on BLA-L09 C432.
Perfect, also because I don't have the Root permissions on the device, and I don't even have twrp. In fact now I have tried and says that it does not find root permissions. Then I did not understand if the phone should be connected from on, in recovery or fastboot?

Tool updated. However, if you don't have root, you can't use it, you must root first.
Okay, I thought it was a tool like the ones we made earlier to install EMUI 9. I'll wait until the new tool is released. : D
