I'm trying cook ROM in czech language (CSY). I cooked ROM based on WM 6.5.3 build 28205 with 0405.mui (CSY) and windows mobile boot no problem but after calibration display, EXTROM doesn't install so I haven't got some Acer utilities. And in Comm manager I haven't got Bluetooth and Wi-Fi. Bluetooth icon is in Settings but if I click on it, it wrote "Cannot start the Bluetooth stack". Anyone help me with this problems?
