[Help][Files Needed] TWRP Backup of CRR-UL00 International Version Required

Hello .
I'll get straight to the point i was trying out the Flyme os rom on the Mate S ( Quite Buggy) so i decided to flash the stock recovery and get back to Stock os .... unfortunately i was frp locked and there was no option in the settings ..... and now im stuck with a buggy flyme os ..... so if anyone can provide a twrp backup of the system or even provide the build.prop from B146 ill be greatly happy .

Go in bootloader and Flash the files from the stockrom cust.img system.img recovery.img recovery2.img Boot.img and userdata.img.........You can extract the files from update.app with huawei update extractor

My Phone is CRR-UL00 Middle East Version .... i flashed roms of CRR-L09 Chinese Version .... that rom doesnt have oem unlock option in the developers option . therefore my device is frp locked and flashing anything in the bootloader mode will fail . thats why i require a twrp backup of the system partition on the CRR-UL00 .

if you are on crr-ul00 firmware ... then unlock frp and flash system.img and boot.img and recovery.img of crr-l09 firmware via fastboot then do normal dload update using crr-l09 firmware

I'm still inexperienced so let's see if I understand ...
I extracted the system.img file , boot.img and recovery.img from CRR - L09 firmware via HuaweiUpdateExtractor .
Now with ADB I install the three files and then do the normal upload via DLOAD .
( I can do this even though I have installed TWRP ? )

after installing adb ..... open cmd and type adb reboot bootloader ........ then type fastboot flash system ....... after typing that drag the system.img file onto the cmd window .... then click on cmd and press enter ..... repeat for recovery and boot.img ...... then do dload upgrade

Super!!!

I can't see what files I need.
I have the update zip and the 2 other zip files.
cant succeed with dload.
how to do the right process?

advice for all people : never flash TWRP in RECOVERY partition, flash it in RECOVERY2 partition to get twrp and dload method works both
to fix your problem you must extract (whith Huawei Update Extractor ) RECOVERY.img from the stock rom (update.app) then flash it to recovery partion then use dload method

ok ty i stopped my search i wait when hisuite think at add the firmware on eRecovery via wifi or via the soft hisuite directly by update ... :/

Hi all
requirement : honor 9 lite with LLD-L31 8.0.0.x(C432), bootloader unlocked.
everyone how flash : you ar developer & tester on your phone ! you carry the responsibility !
i am use pur custom-rom, no xposed framwork ...
can you go with phone in bootloader-mode ?
by me : phone off / usb-wire out of phone / press and hold "vol-down" and put usb-wire in phone. start phone in bootloader : bingo!
you see on bootloader-screen "unlock" & "unlock" in red (by me) the phone is ready to flash
then extract from update.app "recovery_ramdis.img & header" and "system.img & header"
put this 4 files in adb-folder / Windows: open command and cd.. to this folder / on linux open terminal and cd.. to the folder
on my linux-pc i am this files in /home/username/adb. if i start terminal i am automatically in my home-folder and write only "cd adb". this is short-way
fastboot devices (check is phone connected)
if phone connected : fastboot flash recovery_ramdisk recovery_ramdisk.img (extracted out update.app)
next fastboot flash system.img (extracted from update.app)
if this ended : you have customOS on phone
next fastboot erase userdata (this doing what you reed : erase! userdata)
next press and hold "vol-up" and power, phone vibrate and you see Huawei-boot: release power, you see pre-boot messages: release "vol-up", phone boot in erecovery
in erecovery wipe cache and factory-reset . this mace low-level format user_data 0...100%. now is userdate clear and fresh formated. reboot
phone boot as a new phone ! now config, install apps ...
if your phone boot to bootloader and bootloader is unlocked: you can do this how match you need
i test developer-rom's from other phones (oreo) and have this 4..5x doing and it's working way. stony way, hard way - but is working. My phone run.
i hope this is helpful
i hope you think on this: by now is no twrp with working backup & recovery available and i found by now not working developer-rom for this phone. i search continue.
you can on this way only restore the customOS - nothing else. no userdata.
AND FLASH NEVER OTHER as "recovery and/or system". ALL OTHER can brick your phone
excuse my writing "i am use pur custom-rom". i mean "stock-rom" : original manufacturer rom

Just for Info
This is Tread for "Here is the Update.App LLD-L31 8.0.0.127(432)FULL"
Not "how to repair bootloop"
Please make new thread "how to repair bootloop"
i am help if i can help!

other question..
tonight i go trying to flash my honor for install Xposed sdk26 for oreo 8.0.0 i send u my result in 12 hour i think this can work i see that tonight
have a good day

@Pyro.ted
that's a good idea. i not use Xposed. you have custom-recovery and -system and can always reflash - no risk !
i hope for "twrp full function". then we have backup from all and can "test - not working - restore" and "no-risk & full-fun"

... don't work i'v try with arm & arm64 sorry

can i install it in my lld l10?

@leon21062000
lld-l31 = european version.
lld-l10 = ? (country) version.
I do not think so. It can work - but not either, i can not gauge the risk. I mean, let it be better

Trying to update to Oreo

Hello everyone,
First, I'm lost and I really tried searching for answers alone, without success.
I got a P8 Lite 2017 and I installed Paranoid Android 7.1.2 from haki 86
Today I want to update to Oreo but can't find exactly what I need to do, I tried to follow guides but either I can't find the firmware I needed or a specific file...
I got a PRA-LX1 double sim from Europe hi6250 (that's what I know)
I want to move to Oreo because my bluetooth isn't working on that Rom and older haki Roms are all dead links (like his guide on his blog)... :/
If anyone can explain me what I need to do to success the update I would gladely appreciate !!
Thank you !

You need to have both the Bootloader and FRP Unlocked!
Try Firmware finder for huawei:
- download firmware finder on *another android phone* and search for exact phone model (ex : PRA-LX1C432)
- choose the very first firmware (FullOTA-MF without -PV) down the list
*#*#2846579#*#* then go to 2. Veneer Info 1. Version Info and see the exact Manufacture info ex : PRA-L31
Settings / System / About phone and look at the Build number (ex : C432)
-Download @HassanMirza01 TWRP Image. http://www.hassanmirza01.blogspot.it/p/elite-twrp.html
Go and download the right FullOTA firmware (8.0.0.364 in my case, dual SIM PRA-LX1C432 PRAGUE_L31)

-Download update_full_PRA-L31_hw_eu.zip (rename to ''update_all_hw'').
pra-l11_hw_eu.zip if you are on a single SIM device
-Download HuRUpdater from https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279.
Put them (all 4 zip files) on a new folder called Oreo in external_sd.
1 : Flash Twrp from bootloader.
2 : Boot into twrp, click install, select HuRUpdater.zip.
3 : Reboot.
4 : Done.

Thanks, you gave me a lot of useful info. However, I got a problem: *#*#2846579#*#* does nothing and in the info in build number I got: "pa_hi6250-userdebug 7.1.2 NZH54D 1f3ea46c19", I think it's due to the fact that I flash that rom from haki 86... What should I do to have the exact model and build number now that other roms are dead links for now?

No, you have unlocked bootloader..
If you can boot in TWRP then you just have to copy these files to external_sd, make new folder "Oreo" and put all 4 zip files inside.

Good info to know. I was planning to go back to stock EMUI5 from a RR Nougat custom rom.
I've been hesitating which PRA-LX1 EMUI5 to use (PRA-L11 or PRA-L31) and this made it clear for me to decide.

Flashed an oeminfo PRA-LX1 C432 provided by @AltairFR
Now I'll proceed to install a PRA-L31 C432 EMUI5 through dload method.
