so my s2 is rooted and everytime i get a notification of a JB update it reboots and gets stuck with the lil android dude standing near a exclamation point inside a triangle was wondering if there was a better way to get my phone updated i believe it was flashing to stock i believe but the problem is my pc sucks and wont recognize my phone regardless of how many times i uninstall and re install samsung drivers im pretty much left with my SD card is there a route to upgrade my phone thru sd rather than plugging it into my usb into my comp or im just doomed at this point thank you.
