if I have a serial number begins with RPRSTA7Qxx if I can put an unofficial firmware 4.2.2?
Can, but 100% something will not work. options:
1) touch screen mirror or does not work
2) the image on the screen is shifted
3) G-Sensor does not work
4) Wi-Fi does not work
5) simply will not boot
well, or all together. There are ways to eliminate the first two issues in some cases. 3 and 4 also probably can substitute for the appropriate drivers, but not the fact that drivers from 4.0.4 to 4.2.2 will work. If it is not loaded, too, surely something can be done, but there is a bit more complicated to understand ...
