Blackview Hero 2 bricked

[powman]

Download Hero1 FW from Blackview forum, did not realize it is for Hero 1 not my Hero 2
Follow instruction to download ELF file by DirectUSB tool into Hero2....

Hero 2 is not fully bricked, I still see Blackview screen after push power button, but all other button are not working.
Insert SDCARD with Hero 2 Firmware.bin, screen shows firmware update? But cannot update since all button are not working.

Anyone have any idea to fix it?

Thanks~

OK, I fix it by myself..

Download ELF for G90

Download G90 firmware to Hero 2 by directUSB

Hero 2 can boot up now with button working and sound, but screen is not working.

Insert SDCARD with Hero 2 firmware.bin and push power button.

Push button "down" and "OK", Hero 2 start to update firmware, after 1 min, my Hero 2 back....
