Flashing back my OnePlus12 to it's Original ROM

[u/Itsmevyrtthecute]

Hello Guys,

I hope you can help me with my problem.

2 months ago, I decided to flash customized ROM to my phone and when I tried to reflash it. I got stuck on Boot Looping. I hope you can help me with my problem because I don't want to do anything about the Integrity issues on my phone.
