No you can't because you need to unlock the bootloader, which also means that a reset will be performed.Hi, I'm very insterested in this as my father locked himself out of his phone by forgetting the pin of his Huawei P20 Lite...
Is it posible to install TWRP in a phone that is completely stock? I mean, Emui bootloader, and no USB debugging enabled at all? He would hard reset the phone but doesn't want to lose all the stuff in it.
This method is dependent on a few factors,
If the device is encrypted you will not be able to read the data without it being decrypted. If you are using a newer device such as a pixel 3 that has a security chip the lockscreen/boot sequence has been offloaded to the chip as well. I have not verified if the OEM unlock also negates the fact the module that handles your lock screen would be accessible as it is its own entity.
Dirty flash the ROM again..suddenly my phone (G4 H815 lineage ) can't be unlocked (see attachment)
I tried it with but it didn't worked for me...
dirty flash doen't work
when I delete only:
I can get in again, but I can't set a new lockscreen...
when I delete also:
I can't get in anymore...
only wiping data, cache and dalvik works (clean flash)
could this be a problem with system profile settings?
(disable lockscreen when wifi is connected)
