I wanted to install twrp on my google nexus 5x.
Therefore I've unlocked the bootloader, entered fastboot mode and flashed the new recovery file.
I did this with adb fastboot tool.
No errors occured during the process, but after restarting the bootloader and entering the recovery mode, twr opens for a few seconds
and then gets closed again. Now I get an errormessage everytime (device software can't be checked... please lock bootloader) and I'm unable to do anything in the twr menu because it keeps getting closed
over and over again.
Now I can't even start my phone "normally" and can't get a connection with adb (no results when using: adb devices )
Some Bootmenu informations:
PRODUCT_NAME - bullhead
SECURE BOOT - enabled
DEVICE STATE - unlocked
Does anyone know how to fix this issue?
