Hello,

I'm really sorry to bother you on this subject but I can't get my P20lite back to the original firmware.
I tried to downgrade my phone with the firmware "Huawei P20 Lite ANE-LX1 ANE-L21 hw eu Anne-L21 8.0.0.150(C432) Firmware 8.0.0 r1 EMUI8.0" but since then I can't do anything. I can only access the erecovry. I can't do a wipe and multi-tool tells me that :

Could you please direct me?
Thanks

Downgrade from EMUI 9.1 to EMUI 8 is possible through HiSuite only , or, if your bootloader is unloced, through TWRP and HuRupdater.

In fastboot mode run commands:

fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.

Btw, have you tried update via eRecovery and WiFi? ("download latest version and recovery")

Thank you for your help. I succeeded in installing the firmware I put above

Now I have another problem, this phone is from a recycling recovery. They wanted to destroy it because the battery was dead. I changed the battery but I'm facing a google ID.

I have to do a bypass, do you have any idea?
