Question Can´t rollback to Android 11

[jesusanse]

Hi.I´m trying rollback my Nord 2 from Android 12 C.13 (EU version), to Android 11 in order to install TWRP and flash any ROM. I´m using the offical method as this official link https://community.oneplus.com/thread/1596759.
The file I download start to install but at the end I´m still on A12. Anyone can help me?- Thx

Try other version. When I was trying wrong, it stops at 15% and reboot without change.

I tried Global and EU versión and both failed. I'm living in Spain. I suppose that my Nord runs EU version.

Ur loosing all ur data by rollback.....u can try to factory reset before rollback. Maybe this make a difference.

Are u rooted ?
Maybe unroot first ?

Did u renamed the file ?

I´m not rooted. I renamed the file correctly. I´ll try factory resert before. Thx

If still not work maybe wrong destination. It's need to be in memory (not in any folder)
