I flashed a ROM into my Spreadtrum phone successfully. Then I realize that it says no network when my SIMcard installed, and both imei are null. I followed all those method, and none of them work. In EngineerMode I hit Set IMEI, then it show pop up message, Unfortunately EngineerMode has stopped. Other method, in Write Imei tool, I followed the steps, but when i hit write, it says Verifiying on yellow colored background for about 7 secons then it become red with message No respons from the phone. Please help me.
