Unhappy [Q] One S C2 stuck on EDGE after SIM unlock

Hi guys,

I recently had my One S C2 (Orange Romania) SIM unlocked by somebody with JTAG procedure (I don't know how that works, but it's the only one that does, no SIM unlock code option). After unlock the phone kept rebooting every minute so that person reflashed my phone with the latest software available:
  • RUU_VILLEC2_U_ICS_40_S_HTC_Europe_2.15.401.100_Rad io_16.21.20.02U_16.09.20.11_M2_release_286571_sign ed.exe
  • OTA_VILLEC2_U_JB_45_S_HTC_Europe_3.19.401.101_16.2 2.20.03U_16.11.20.24_M.zip.

Now the phone is working but I have on 3G connectivity.

I saw a possible fix here - http://forum.xda-developers.com/show...160389&page=19 - but it seems to be for One S S4 version.

Already tried reinstalling RUU_VILLEC2_U_ICS_40_S_HTC_Europe_2.15.401.100_Rad io_16.21.20.02U_16.09.20.11_M2_release_286571_sign ed.exe, but no go due to bootloader missmatch (newer hboot on pone already).

Any help would be greatly appreciated
