Member: 362673 Status: Offline Thanks Meter: 37 | I have six one in this case and i am looking for the solution. I repared one with Ns pro, i make a full reset, you enter in SERVICE after having select the model U600. You make NVM full reset, custom reset, wap reset...... but not the latest one (Build defaut NVM). After this, you make lonely a "BUILD DEFAUT NVM" and You repeat and repeat this operation many times and it will screen "charging", after this, you must let the phone connected at the ns-pro and you switch on the phone. You make*2767*3855# two or three times and when the phone restart you disconnect the u600 from the ns pro. If it is ok, then make a fullflash. Post the result, it can take twenty minutes to screen correctly. bye |
