Does anyone know how to fix a bootloop? I have tried flashing a stock room using Heimdall but that only makes the phone show to Samsung logo show the erasing animation for a little bit and boots into download mode and show "Error validating footer (6)" . If I try to generate a vbmeta file with abvtool it shows the warning that says that unofficial software was installed and shows the unlocked bootloader warning and after that it reboots.

  • @alecxs After un tarring the stock ROM. I found only a "vbmeta.img" file and no "vbmeta_samsung.img". Could this be because I downloaded the firmware from "samfw.com"?

  • @alecxs So if that does not apply to my phone is there any other way to unbrick my phone or should I just try to flash "vbmeta_samsung.img" even if it is for another phone or version?

  • @alecxs But after flashing TWRP all the phone does is show to unofficial software was installed, show the unlocked bootloader warning and reboot.

  • of course easy way is flash stock ROM but it will re-lock bootloader and you might not able to unlock again because of samsungs restrictions. you can install TWRP and AOSP instead

Try using the Samsung Smart Switch app for PC to restore the stock ROM.
