  1. I tried this beta firmware... the only flaw it changes the imei (to 00499...), and so no mobile network for voice...
    there is no easy way to put back the correct imei...
    only reverting to current 4.1.2 bring back the correct imei and network is recognised...

  2. It is easy to put back the correct IMEI.
    You have to open the .tar.md5 file from an original earlier firmware (4.1.2 for example) with winrar and extract the modem.bin file.
    Then, in Odin, flash that single file by selecting it in the phone box.
    This will put your e-mail back to the original, and network connection fully functional.
