Make sure you have your 2.1 firmware inside the "firmware" folder.
1: press start and search "regedit"
2: click edit>find, and type in "Vid_0fce&Pid_adde". You should find "DeviceInstance". Copy the last section of that, it should look something like "5&2888d0ff&0&1"
2.1: If that fails to see anything, make sure "Match whole string" is un-ticked, and click "find next", if that fails, try "USB\VID_0FCE&PID_ADDE"
Note: It changes with every diffrent USB port you use
3: Put that number into DeviceID.txt
4: Open up x10flash.bat, and answer the question (s)
5: switch off your phone, hold DOWN the Back key on your phone and plug your USB cable into the top of your phone, and press enter.
If done corrently it should start going through all these commands.
As stated above, it MIGHT take awhile to boot your phone at first, its not instant. Just give it time.
