Re: [Q] I717 laggggg so bad
I have this exact same issue. I unrooted with Odin back to stock AT&T i717 from Jedi4 ROM (where this issue of crazy lag first occurred after first flash of said ROM and used twrp to wipe and re-flash like 5 times with several different radios). After going back to stock ROM via Odin I then used the stock recovery to perform a factory reset and cache wipe and the lag will not disappear. Even worse it causes system restarts every couple of minutes.
However, between the crash restarts I was able to see that the baseband is the same modem I flashed when I was flashing several different ROMs (in hopes of getting a T-mobile signal on my AT&T i&17, to no avail.) Through the method of deduction, this must be the issue. Since I am back to the stock ROM, how can I change this? I have a backup saved in Kies that was before I ever first flashed the i717, my guess would be to try restoring the phone that way but if there is another way to change the baseband back to stock and therefore cure the issue without being rooted, I am all ears.
