Here's the problem: I'm not getting 4G/LTE signal, even in dense urban areas.
I think I need a new SIM, which will entail a trip to the Verizon Store, which means un-rooting.
I recently upgraded to a Galaxy S4. I have Unlimited Data, so I did the upgrade on another line, then used my existing SIM from my Galaxy Nexus to activate. It seemed to work fine.
Then did the following:
• WiFi Tether hack
• Installed Xposed and Wanum to remove custom boot screen
So I read the various un-root threads. This seems the most useful:
but I'm concerned about the warning about losing the Loki Exploit and not being able to re-root.
If I ODIN the factory image, will I still be able to root it without Loki?
Other threads recommended a full-reset, which I did from stock recovery. Afterwards, I am still rooted and the Custom boot screen still appears.
So, how can I get back to a factory state to get a new SIM and then still be able to re-root?
Being able to use SafeStrap would be nice, but my main requirements are Root and WiFi tether. I can live with Nova Launcher over stock TouchWiz. I backed up the customized image in TiBu so I'll be able to restore once re-rooted.
