OPPO Find X2 Pro

My Find X2 Pro is on Android 11, C59. I used the sec5 tool method to convert to SingaporeEX to originally get A11 so have been ‘stuck’ with a Singapore rom since (originally Australian version).

I was considering doing a downgrade back to A10 then flash the latest Australian A10 rom, to get back to an Aus version.

The trouble is, I’ve followed the

instructions

and downloaded every rollback rom (I found a few websites which gave slightly different versions of a rollback rom, see photo) I could find, but none have worked. When clicking on the rollback file in file manager, as instructions say to do, I get “Failed to extract. File may be corrupt” (despite downloading several times in case it was a bad download) and when trying to install through recovery it says the file is older than my current version and won’t let me flash it.

Anyone had luck or have a suggestion?!?
