  • Cuando haces la instalación, todo funciona, exceptuando la sim!! Algo muy importante. Además cuando te vas al apartado de ajustes, cuando vas a entrar en el apartado de información de software, se queda pillado y no puedes entrar. Supongo que tendré que instalar una kdz, pero menudo marron tener que meter root y recovery de nuevo. Si se conoce alguna solución que no pase por flashear una kdz me gustaría conocerla. Por si os sirve de ayuda al iniciar el teléfono me sale una advertencia que indica exactamente esto: WARNING: Current version is not avaiable for user. Can’t find matched cust for NT-code mcc/mnc[FFFFFF], subset[11]. Gracias

    When the instalation ends, everything works fine, except for the SIMCARD!! That is very important. Also when you go to Settings/About Phone/Software info, the phone get stucked, and after a few seconds it goes to the launcher. So I can’t even see my software info. I supose that I would install a KDZ, but my root and recovery will be erased, and that’s a shit. If someone knows how to repair this without installing a KDZ let me know please. If it helps you, when I boot my phone up, the phone shows me a message that says exactly this: WARNING: Current version is not avaiable for user. Can’t find matched cust for NT-code mcc/mnc[FFFFFF], subset[11]. Thank You
