Warning:
GSF is a 16-digit RANDOM number, which may impact the success rate.
You may not get this fix in one shot, and most likely you need to be very patient to keep try.
Hint:
if you get a GSF# starting from two numbers, feel free to take a chance to continue following the guide, but most likely you need to re-do everything again
If you get a GSF# starting from a number following with a letter, then the success rate is over 90%
