Ive never had this trouble flashing a rom before on my old phones. Ive got an sph-l720 galaxy s4 from sprint, it was running 4.3. I successfully rooted it and installed CWM. I had just activated the phone everything was working. I flashed a rom called "Darth Stalker". Once it was installed everything appeared to work. But it turned out the only thing that did was wifi. No data, I could receive texts but if I tried to reply Id get error code 0.
I tried to restore my nandroid and it keeps failing on restoring /system. Any ideas what the hell is going on here??
