Thanks for the clarification, did the cold flash and things are back on track...except that it seems the image I used was intended for Vietnam or something like this. I have changed all the language and text input to English, but it seems when using some apps la Opera or Twitter, that somehow the device is fetching this Vietnamese option from somewhere. Is any way to change this to English or do I need to use a different image, like for example some Northern Europe one...

Just to be more clear. I have flashed this image:
43AD05DD_DFL61_HARMATTAN_40.2012.21-3.454.6_PR_LEGACY_454_ARM_RM-696_PRD_signed

is it better to use one of the images below? if yes, which one?
29FAD658_DFL61_HARMATTAN_40.2012.13-7.NORTHERNEUROPE_EMMC_NORTHERNEUROPE

or

DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM
