So, let me make report. With some difficulties I made S-OFF and root. But ClockMode application does not support this model yet. At the moment I do not have possibility to install ZIP and get functions of Recovery. But, I put your latest Install and Application from the Google. Now I tested the phone just with 1 main SIM. It connected to the PCM with your application and work!, BUT approximately in 40 sec. connection drops down. I tried the function of your app - prevent to sleep. Does not work. So, result - work, but just for 40 sec. Please, advise which data you need to fix it?
