I did hard reset of my phone, then after that i noticed that my sim card was not detected,
on the phone status it shows "Serial No. = ERROR, EMEI1 = UNKNOWN, EME12 = UNKNOW.
But thanks jamezon3_18 of http://www.symbianize.com I was able to bring back my phone to normal.
Here's the step i did:
- Download Drivers
- Download EMMC Download
- Download this file BAK.qcn
- Connect your phone to you computer
- On USB debugging, select "Charging Only"
- on your PC, open device manager (you can see a Yellow Question Mark for Android)
- Right-click, then update driver, browse "..\drivers\USB Modem Driver\Win32", w8 until it finished. (you may skip this step if the driver is already updated.)
- Open EMMC_DownLoad_V1.2.4.exe
- Click Restore_NV
- Browse the BAK.qcn
- Click "Open"
- Your phone will automatically turn off
- Turn on your phone and BINGO!..
Conclusion:
Before doing anything like factory resetting, updating firmware etc. you must backup first the NV using EMMC Download.
