- Download the Huawei Update Extractor
- Download an official firmware update
- Extract RECOVERY.IMG from Update.app with the Extractor
- Flash the Stock recovery using fastboot
- Done, now you can upgrade using the OEM updater
A little tip from myself, next time you flash TWRP, flash it on RECOVERY2, this way the emergency recovery gets overwritten instead which you can access by Volume+ & Power buttons and the original Recovery still remains the main.

How can i flash twrp over recovery2? Whene i flash its only overwritte first recovery.

Bootloop Issue P7-L10

Hi guys, I'm completely newbie in Adroid stuff, and need help to get back my phone.
My software:
ROM Versio: V100R001C00B133SP01
EMUI: 2.3
KitKat​[/INDENT]
So, what I did before:
Unlock boot loader
Installed TWRP 2.8
Installed Kingo Root
Got rooted
Installed Super SU​
My issue:
Following the article, posted on this thread link, I got some some errors, then I tried by myself extract boot, cust, system and recovery from Huawei Extractor for ROM: Sophia-L10_V100R001C00B621_Firmware_West%20European%20Region_Others_Android%204-2 and ran the following commands using ADB:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img​
After doing this, my phone got in boot loop, I did some search here, and found a force recovery method (putting B133 ROM on SD root directory DLOAD folder and tried force update without sucess.
Does anyone any suggestion to get my phone back?
By the way, my final gola is got Lollipop or Marshmallow working on this phone if it can be alive again
Thank you,
Ivan

Update from VIE-L29C636B360 to B362+

Situation
Currently I am running VIE-L29C636B320, with EMUI 5 and Android 7.0. The phone is runs fine
So when I am to install , boot to recovery mode:
It gives
"Your device is booting now... "
And stuck there forever. I can get my phone back to working state by rebooting 3 times.
I tried the following methods..
> using dload+**#*#2846579#*#*, )
> I currently cannot boot into TWRP at all (I am using TWRP3.1.1 for Huawei p9 plus already), and all the key combinations doesn't work.
> Firmware Finder with Proxy Add-on
> fastboot flash reccover twrp.img (phone oem unlocked already)
> Huawei e-recovery does not detect any packages to download.
So I suspect something wrong with my img files..
My plan is:
Using Huawei Extractor to extract all img's (system, boot custom and recovery) from B360
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img
It took me a while to get to where I am now from EMUI 4.1. What I don't want to is lose my working phone and make my phone completely useless.
So my question is, are the above steps no u-turn and I would completely screwed? Or safe to get those img's back and then I should be able to continue to upgrade from B320 to 362 and onwards?
Since I cannot boot into TWRP, I can't take backup of my phone..

Bootloop

I had installed TWRP and it was working fine.
I then installed SuperSU-v2.82-201705271822 via TWRP.
This did not root the phone, rootchecker etc. all said it's not working.
I had made a TWRP backup of the phone before that.
I then tried to restore that backup, and now the phone only starts either into the TWRP boot screen, then reboots endlessly, or goes into the Huawei recovery, and fails to download the recovery package there.
Any ideas?
I can get into fastboot and download mode, but using dload found on another thread here fails at 5%.

Got it fixed. Had to flash both kernel.img AND system.img for it to work, without kernel, it kept looping.

I'm in the same situation, can you please help me?
I tried to flash SuperSU but got stuck in a boot-loop. Did you flash the kernel.img and system.img extracted from a stock firmware update.app file? I tried flashing those two but am still stuck at the boot animation. Occasionally the device will automatically reboot from the boot animation and enter eRecovery, which always fails to get package info.

Mine were from update.app. I had also flashed vendor.img, not sure if that is related.
You can also try this:

The recovery is compatible. Since you can't boot to system, make sure you run the adb stuff in TWRP, then flash to the nocheck recovery in fastboot mode afterwards and follow the rest of the steps.
Huawei's recovery servers are down, that's why erecovery fails.

edit: nevermind, got kernel.img extracted by disabling "Verify Header Checksum" in Huawei Update Extractor settings. This post can be deleted.

need twrp backup
anyone have twrp backup for lld-l21 please help

How to extract stock recovery and ramdisk img files from UPDATE.APP

I downloaded UPDATE.ZIP and got the UPDATE.APP file from there.
I then extracted recovery_ramdisk_a.img and ramdisk_a.img, and flashed them in the phone, but it bricked my phone: not booting, no recovery, no fastboot (fastboot devices show empty; it gives Error 10 and 20 No boot on the phone)
Somehow after a few reboot, it got itself into a erecovery and downloaded full stock image and reflashed. Now it is unbricked.
Am I missing any steps? Why are these img files bricking?

Anyone knows please help

How did you extract the imgs from update.app? did you use Huawei Update Extractor tool?
