Problem 5: Device shows NO GSM when booting
The radio stack is screwed, you don't get GSM signal and the phone says unknown SIM status
Device won't start after trying to unlock it with HTC Universal Unlocker (HTC_Uni_SIM_Unlock_v1)
Here is how to fix it:
Disable activesync on your computer by right click on activesync icon -> connection settings -> uncheck "allow USB connections".
Put your Hermes in bootloader mode
Connect device to computer using USB cable.
Open mtty.exe and select USB port, then connect.
Hit enter twice, you will see the "USB>" prompt.
Type the following commands (do not copy paste!!!)
USB> password 0000000000000000
USB> set 1e 1
USB> erase a0040000 c80000
USB> erase a0cc0000 c80000
USB> erase a1940000 640000
USB> set 1e 0
Reset your phone and put it back in bootloader mode
++++ Vì T-Mobile chưa có rom nên chưa biết làm sao đây
