Iphone 3GS showing no service/1bar signal on 6.1.6 JB unlocked tried everything...HELP
Hi guys, I am usually over wpcentral for as my daily driver is WP, but I have another phone the 3GS that has served me well for 3 years but after the update 6.1.6 it started showing no service... Tried everything from JB, rolling back to prev version (have SHSH 6.1.3,6.1.2,.6.0.2, ios5 and ios4), baseband upgrade/downgrade, ultrasn0w, SAM, tethered boot, untethered it just doesn't work... Kept mint for all this time never dropped, never opened, worked perfectly and suddenly... it does not.
Would you be kind enough to give suggestions to what might be the problem... (Don't suggest me to buy a new phone unless you plan on donating the money for It)
