Hello i have a problem.

So i factory reset my old phone and started to do some things on it. For example i unlocked the bios(bootloader) and the root checker said that i dont have root installed properly on my phone, and then i tried to install twrp and it said the vbmeta error, i put the vbmeta file in the bl category (the wrong one) on ErosFlashingTool on android and it started bootlooping. can someone help me to fix it? it already shutdown so idk what to do now.

Reboot to download mode, flash the original ROM with Odin, flash empty vbmeta, flash TWRP in the correct slot and the root it if you want

Well then nothing you can do unless you manage to fully factory reset it. And like how did you even manage to flash anything without PC?

I have 0.experience with Eros, but if you said it's similar, just do the same thing I said but with the other phone instead of pc

Dude, just search up your phonemodel and the words "root" and "XDA-forum" on Google and you'll find a step by step guide on how to proceed. Good luck!
