I installed the T-Mobile I.C.S. I am not happy with the radio. I tried to flash a radio from 2.3.5: for the first time successfully, but the radio version has remained the same in the settings. I decided to repeat the experiment. Flashed a second time, radio has changed in the settings, but the phone went mad and became uncontrollable. I panicked, ran without thinking, and tried to FlashIt rolled forward stock T-Mobile. Oops.
It's not all. On the screen appeared a red logo and the screen goes black. I was able to go into ap fastboot. I tried to flash it with different firmware (via the flashit and the RSD). And even charge the phone two times (there was even the animation is charging). I still did it. FlashIt - T-Mobile Stock - Recovery - I.C.S Leak. Everything is working. Only there is no Root and radio quiet.
Unfortunately, I can not remember the sequence of their actions. flashed that one, then the other way. And at first tried the firmware is different, in different order.
