What this can fix:

When booting, you get this error:

Func NO : 10 (boot image)

Error NO : 2 (load image)

When booting to recovery, you get this error:

Func NO : 11 (recovery image)

Error NO : 2 (load image)

Bootloops

Can't boot into fastboot

Can't boot into recovery for other reasons

Can't boot to system for other reasons

ETC...

First thing first, there really isnt a way to keep your data so expect it all to be gone, unless it is saved on an external sd card. Also, this guide is specifically for the PRA-LX1 model, however it might work with other p8 lite 2017 models and a similar method may work with other huawei phones.

Requirements:

The device boots in to fastboot mode. (If it does not, scroll down to problem 1)

You have a pc with a usb port and fastboot/adb installed

You have a micro usb to usb cable.

Unlocked bootloader and oem unlock.

Micro sd card

Problem 1: Can't boot into fastboot?

Try this:

1. Make sure device is fully powered off

2. Connect device to any pc.

3. Press and hold volume- and power button at the same time until your screen turns on.

If this doesn't work then unfortunately i can't help...

Problem 2: Only fastboot boots, but not recovery or os:

Lets start by flashing TWRP...

If your device was on android nougat (7.x.x) or the rom you were flashing was nougat based then do this:

Download this file:

https://drive.google.com/file/d/1TjNHI9FNdwQS2HphsjGfQCHKephibiKn/view

Boot into fastboot on your phone and open fastboot on your pc

Type: fastboot flash recovery *Nameofrecovery.img*

-----------------------------------------------------------------------------------------------------------------

If your device was on android oreo (8.x.x) or the rom you were flashing was oreo based then do this:

Download this file: https://drive.google.com/file/d/190zqju8ZmwZCzI4WXtujgKLFXvvuWTk8/view?usp=sharing

Boot into fastboot on your phone and open fastboot on your pc

Type: fastboot flash recovery_ramdisk *Nameofrecovery.img*

Problem 3: You can only boot into fastboot and TWRP recovery:

Thats OK! Heres how to restore the phone:

IMPORTANT: THE FILES LINKED HERE ARE ONLY FOR PRA-LX1 DEVICES! If your device has a different model number, or these files did not work for you, follow this guide to get files for your device: https://www.mrviking.co.uk/440246340

This will also update your device to android oreo!

Put the micro sd card in your pc.

On your pc download these files:

https://xdaforums.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279 (Download 0.3)

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1194/g104/v148634/f1/full/update.zip

http://update.hicloud.com:8180/TDS/...altice_all/update_full_PRA-L11_altice_all.zip

http://update.hicloud.com:8180/TDS/...34/f1/full/public/update_data_full_public.zip

Now Rename update_full_PRA-L11_altice_all.zip to update_all_hw.zip

Also rename update_data_full_public.zip to update_data_public.zip

Put all four files: update.zip, update_all_hw.zip, update_data_public.zip and HuRUpdater_0.3.zip into one folder on the external sdcard.

Take sdcard out of pc and put it into phone.

Boot into twrp tap on mount and select all partitions

Make sure 'mount system read only' is NOT checked.

Go back to twrp home

Go to install, find the huruupdater zip file

Flash ONLY hurupdater, DO NOT FLASH ANY OTHER ZIPS.

Follow instructions on screen.

Reboot to system and wait for the device to boot.

If it didnt boot, dont worry:

Go back to fastboot mode on your phone and pc, and download this file: https://drive.google.com/file/d/1daIos0yagHk9Kg-5hXLDwNYDHjP_N0EM/view?usp=sharing

Flash it with fastboot using:

fastboot flash recovery_ramdisk *Nameofrecovery.img*

now boot into recovery wipe cache wipe date/factory reset reboot to system

If none of this worked, try this last resort. (Likely won't work but it is worth a shot)

Firstly, place your micro sdcard into your pc. Create a folder called 'dload' in the root of it.

Now, locate the firmware files you downloaded from firmware finder.

Open the main update.zip file and extract the 'UPDATE.APP' file to the 'dload' folder in your sdcard.

Place sdcard back in phone

Make sure phone is powered off. (Can't power it off? Unplug anything connected (charger, pc, etc...) and hold the power button until screen goes black)

Hold all three function keys (VOL+,VOL- and POWER) until screen turns on.

Hope it works and wait
