I have flashed the LS995 Rom that you provided to return to stock, and yet the knock on is not working. I dont know why.
Yes, the ATT Rom that you provided is great, it can repair the Knock by access the dialer code.
After I fix the knock on, and I use TWRP backup to restore System, Data, Cache, EFS, Boot, but the knock on is gone again on Sprint Rom.
Do you have any guide to restore back the knock?Or I perform a wrong way?
Or perhaps there's a way just to get the touch firmware from AT&T or AT&T Hidden menu LoL and install it to Sprint LS995 Rom.
I would appreciate your help.
