Huawei p8 lite Bootloop Fix

[jankramer]

so i had a p8 lite wich i tried rooting and it got stuck in a bootloop.
this worked for me
WARNING: this does delete everything you have (actually that is already gone)
(read all the way before doing anything)

first i set up adb & fastboot on my pc

2nd i downloaded stock firmware from huawei site ( you can also get this from rootjunky)

3rd i used HuaweiUpdateExtractor to get the recovery boot system and cust out (out of UPDATE.APP the one from the firmware)

4th i booted my phone into fastboot (i connected my phone to my pc first because otherwise i couldnt get into fastboot mode)

5th u start the command prompt in the adb&fastboot folder and type these commands (if you dont have custom recovery or custom roms you can skip to 5(i think i didnt do those)) :
1 adb devices (if it doesnt find it wait some time or reconnect it it will pop up sometime)
2 fastboot erase cache
3 fastboot flash boot BOOT.img
4 fastboot flash recovery RECOVERY.img
5 fastboot flash system SYSTEM.img
the system .img is too big so it will go in 6 parts and will often fail but just keep trying make sure to wait long enough because maybe it is still busy
6adb reboot
it should start up now.
these steps worked for me also when i did step 2 i could get into Erecovery wich i could before but now i could erase cache and something else and do a factory reset just press erase on everything then continu

will try it

Hi Jan thanx will try it and let you know . Coz currently my device can only go into fastboot and rescue mode nothing else and with commands I can only use fastboot commands ofcoz and not adb commands coz my device is not in debug mode .

Bootloop

My phone is not unlocked but i have managed to bootloop it when I tried to downgrade it using update.app but now when i try to use the update.app method it gets to 5% and then displays update failed.
When trying to run any of the fastboot methods you mentioned I cannot run it cause it displays "failed (remote: command not allowed)"
I do not have the bootloader unlock code as huawei is being retarded and do not provide that sevice no more can anyone help??
its a Huawei P8 Lite(the old one) ALE-L21 and came with C02 firmware.
