Hi, i need your help.
My Samsung Galaxy A30 (A305G) doesn't turn on. It stays in bootloop and if I try to boot into Recovery, it doesn't work. The device has the bootloader locked and it also doesn't let me flash any stock / official firmware.
When I boot into recovery, some letters appear at the bottom of the screen, which say the following:
#no data on recovery_cause#
#Reboot Recovery Cause is [UNKNOWN]#
Support SINGLE-SKU
Block-Based OTA
Supported API: 3
E: failed to mount /efs (Invalid argument)
# MANUAL MODE v1.0.0 #
E: failed to mount /cache: Invalid argument
E: failed to mount /system_root: Invalid argument
E: failed to mount /cache: Invalid argument
E: failed to mount /cache: Invalid argument
E: failed to mount /cache: Invalid argument
': Can't mount /cache/recovery/last_locale
after that, it restarts, returns to recovery and repeats the same infinitely, a kind of bootloop but in recovery.
What did you do/flash to this before it came into this situation?

I can use every rom just fine. However, I need to flash stock rom but when I boot to stock rom it says "No Command". After a minute or so, the screen changes to installing system update, which flashes to black every second.
Stock firmware that I flashed is "J710MNUBS4CSF1_J710MNICE4CSD4_J710MNUBS4CSG2_HOME.tar.md5"
When I press Power + Vol up in the "No command" screen, this is what the text reads:

Just reboot to system and that's it. Unless it just boot loops back to recovery.
