I was doing something wrong with the 3310 flash. Of course I did flash it twice. 3330 flash also works.
The problem now is that I cannot unlock the sim. Practically no MBus programs work for me. If anybody has a 3310 or 3330 flash that surely works i'd be glad to use it. I suspect it will need a patch at the service locks. Even if i put an unlocked 3310 firmware with faid check and mcu check it has all locks closed when I look at it with noktool.
So there is a way to know it's not a 3310 besides the memory sizes
