3uTools-Forum

Guys, I need help. I have iPhone 4 with OS 7.1.2. It won't activate on fresh system, it will not activate through iTunes and through 3u tools. Sim card is good and active, however phone keeps showing "No Service" instead of network name.
I tried downgrading to IOS6 but I only have shsh file allowing to flash IOS7.
Need a help with that please.

Bypass the activation screen, then re-jailbreak. Check on youtube

Well the only way I found on YT is the 112 or 99 emergency call and then power button but not only it doesn't work - also, my phone is calling emergency immediately. It really connects fast where I am and I called emergency services 4-5 times. Do you know of any other method ?
