I messed up with everything. The only thing that works it's fastboot, I can still flash .img but when I reboot it get stucked on bootloader and can't enter neither recovery or system(Just erecovery but that's pretty useless).
I've tried flashing twrp or stock recovery, even tried to flash kernel/ramdisk and system image from stock rom but the result is the same: I always get "OKAY", or "flashed successfully" but gets stucked then. I took the images I've been trying to flash from Firmware Finder:
STF-L09SC432B372 (184.108.40.2062) FullOta-MF STF-L09C10B370 (220.127.116.110) FullOta-MF STF-LGRP2-OVS 18.104.22.168 FullOta-MF
If you can help me I would really aprecciate it. Thanks in advance.
p.s. bootloader and frp unlocked
