[Please help] I can't restore my Blackview BV5500 after an unsuccessful twrp.img firmware flashing
[Please help] I can't restore my Blackview BV5500 after an unsuccessful twrp.img firmware flashing
08-02-2026, 12:46 PM
One day I wanted to flash TWRP Recovery, unlocked the bootloader, flashed the twrp.img file (supported by the phone) into the RECOVERY section, rebooted - and the phone couldn't even turn on...
I tried flashing through the SP Flash Tool, MTK Droid Tools, MTKClient, Miracle Box - the same super-sign.img doesn't work in any way (2.3GB) of suitable firmware (BV5500_S2_210611), suitable preloader (e531_dk_dk008s...)
What do I need to do to at least sign and flash twrp.img?
I have a backup

You should easily unbrick using SP flash tool @ https://www.hovatek.com/forum/thread-159.html or MTKClient + SP flash tool @ https://www.hovatek.com/forum/thread-46342.html (if it requires a custom DA file).

Speaking on TWRP, did you first disable dm verity ( https://www.hovatek.com/forum/thread-32719.html) before flashing the TWRP? Failure to do this could result in a bootloop

Did the device at least boot up after you flashed all except super?
