- You need to download the firmware of your device. Please check here the The_ERROR thread wich explains it very well:
- Download KDZ updater from here and uncompress it
- Install msxml.msi from the uncompressed directory
- Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator).
- Select Type : 3GQCT
- Select PhoneMode : DIAG
- In KDZ file : Choose the ROM file you downloaded in the first step
- Press Launch software update and wait (It will be 10 minutes or so). In your phone it will appear "Emergency mode". Wait until it reboots.
INFO : I will not be responsible if you brick your device. Do it at your own risk! Has everything envolving flashing, it allways has its risks!
