Hi
My phone stuck on logo when i start it and when i restart it in recovery mod i got this message Failed to mount /efs (invalid arguments)

How to fix it plz?
I can’t write efs cuz it requires adb and phone stuck on logo on boot

I flashed combination and it’s working ok and i can get calls
But again when i flash it with other version it again stuck on logo and in recovery mod it shows : failed to mount /efs (invalid argument)
Help plz

Hello
Most case it was imei cert damaged by others you got phone in logo condition so you can not verify it.
Now once phone is starting up fine make readinfo uart and check what is condition of IMEICERT & MIPI if exist.
