imei change only imei patch it doesnt change real imei.. original imei stored in OTP area.. an imei patch will lose after a full flash..
OTP area can't reprogrammed in any phones.. also in motorola Blank mode means that OTP Area empty.. its special mode phone accept all commands that not mean in Blank mode u can't send command to re-write OTP Again (OTP One-Time-Programmable) ;) i hope u undst...
Blank mode using for Unlocking moto phones with New bootloaders that normally can't accept Unlock commands / to Rebuild corrupted Security Area..
Only one time can write imei to an OTP Chip.. After programming OTP Area Bits will be changed in flash chip
