ragazzi vi posto una guida presa da xda...spero i mod non mene vogliano male...la ho provata e funziona perfettamente ora ho di nuovo il bootloader vecchio
1. Always backup first, full wipe yor S3 and flash back to lastest stock ICS 4.0.4 rom not included old bootloader in it or you can fash via Mobile Odin and don't care it include a bootloader or not because Mobile Odin doesn't flash bootloader.
2. After flashed ICS 4.04 rom don't root or do another work on it, Just check OTA update on S3 by Go to Settings > About device > Software update > Click Update. Let OTA update your S3 to JB 4.1.1. In my case the OTA will update to JB 4.1.1 XXDLJ1 and it takes about 2xx MB size. Yes, it's here. The processing of OTA update from ICS 4.0.4 to JB 4.1.1 can break the protect of new bootloader XXELLA . And after OTA updated to JB 4.1.1 you would have the old version of JB 4.1.1 bootloader. In my case it's bootloader XXDLJ1.
