Can't do any operation that requares to boot via ROM (2+5), when i chose for example to reset user code, then i need to connect via "C" and eerything is ok, But i want to fix Semc Boot damaged previously with early Aerix version while unlocking. So i need to press 2+5, and when i press i just noticed that on the left shows up SEMC FLASH DEVICE or something, but operation does not even start, and after 1 to 2 minutes my phone turns on itself. and stays in MASS STORAGE mode. i have c510 cid 52 red. and use GG Drivers v2.2.0.6 (tryed many versions).
