While many members come to XDA to flash the latest and greatest ROMs and kernels, and perhaps find a cool mod or theme, there are some members who enjoy living on the bleeding edge of development who flash just about anything from experimental leaks to radios from other devices. Of course, keeping up with all this development work means dealing with some unscheduled issues and bugs as well. While no one likes bugs, they’re kind of like puberty—eventually, it happens to everyone.
Of course, with every bug comes a fix and for those on the AT&T Samsung Skyrocket who have experimented with the a Samsung Galaxy Note radios, you may have run into a few problems that can now be fixed using not one, but three methods in a thread posted by XDA Senior Member icenight89.
The first method runs the user through manually replacing a file that would normally fix the problems. It isn’t very difficult, and really only requires users to flash back to Android 2.3.5 and a root file explorer to use, and then flashing an ICS ROM to complete. The second method runs users through a computer-connected method where ADB is used to push the proper file—called keystr—back onto the device. The third method is for when 1 and 2 don’t work, and comes in the form of a flashable update.zip file that puts the file back for you. In all instances, however, the first step is removing the Galaxy Note radio, and getting back onto the firmware intended for the Skyrocket. Apparently, the radio for the Galaxy Note has a tendency to do all sorts of things to the Skyrocket, such bypassing the lock screen and /efs corruption.
