Christophe Devine devinechristophe at gmail.comHi, It should be noted that the new bootloader is very limited (no charging, no loading of the regular phone os). I found another tool, called "C139 FULL SOLUTION UNLOCK AND FLASH", that successfully could flash a proper firmware (European_Software in the archive it is version 1.0.03.E): https://drive.google.com/file/d/0ByHQWL5Q6bSwTWdhRFAyU05uLUk/edit?usp=sharing Nonethless this particular (trac)phone is still limited to the US bands.
