I'd like to ask if I can safely downgrade my current XXUEML9 ROM to some older releases of 4.3 s3 i9305 official Samsung ROMs.
Why do that? I've read some reports that first releases of 4.3 ROMs for i9305 could be rooted with kingo without tripping knox flag and the XXUEML9 release has been reported to be tripping the flag (some new samsung's security measures introduced meanwhile), so I think it could be worth trying but better safe than sorry - I know I can't downgrade to 4.1.2 or whatever under 4.3 but what about new 4.3 to "older" 4.3? Just wondering if there aren't safety patches in the bootloader itself that prevent users from downgrading to anything lower than current FW
Thanks for your help.
