yesterday i was updating my universal (XDA Exec), with this file:
254304-9000_rom_1[1].30.77_extrom_1.30.176_radio_1.09 (aku2).zip
downloade from xda-developers.
Main problem with update is this exe file, so the easiest way is to extract the exe file, and put ito the catalog with extracted files this tool:
MaUpgradeUt_noID.exe
then the upgrade process is very easy.
First of all you will get a message which says that you have incorrect local settings or wrong language. Start the program once again, without doing anythin with the pocket, and the upgrade process will start.
Remeber to unplug SD card and SIM card from your PDA.
Regards.
