Let me explain my situation; I have a rooted device with custom recovery TWRP-2.8.7.0-thea.img., upgraded to lolipop 5.2 some months ago and now I accidentally forgot my android lock pattern after quickly changing the pattern. And now I wanted to factory reset via fastboot, but it just went into normal powerup.
Recovery will not boot in fastboot mode. I get this error "boot up failed"/ I flashed recovery with fastboot
Fastboot commands that I used:
C:\Program Files (x86)\Minimal ADB and Fastboot/fastboot.exe flash recovery C:\a
ndroid/twrp-thea.img
I also tried: fastboot erase recovery and redo the command above but still fails with the same error "boot up failed"
Bootloader: 411A
Build version: Blur_Version.23.21.17.peregrine_reteu.reteuall.en. EU
