Phone unbootable

[ZaroxJH]

A while ago my LG Q6 turned off since the battery was drained, the phone was turned on when this happened. After charging it again and trying to turn it back on, it wouldn't turn on. All it does, is vibrate and show nothing on-screen. After about 20-30 seconds, it vibrates again in a constant loop. I have tried entering both recovery and fastboot, both to no prevail. The only sign of life, is when I plug it into the charger with the battery removed. This will show the battery icon with a question mark, which means the screen is fine. Is there any way to fix this issue or am I boned?

you may able to fix with SALT or if you find prog_emmc_firehose_8940_lg.mbn signed for LG you can use edl tool to access raw partitions. there is maybe a way to boot modified kernel that gives you root access, so you can try to decrypt and backup userdata from adb shell.
