I'm running Jedi Master X2 on my tmobile note 2 and have been seeing many issues with regards to connectivity. Rarely I can get 4G LTE and most of the times it drops to 4G, 2G or loses data all together. It seems very random at times. When data is lost it will either say 'searching' or it shows 'not registered on network'. I read some other forums and the 'not registered on network' issue seemed to be related to the wrong/blacklisted IMEI, but i can see mine just fine.
I've also attemped to go back to the stock 4.3 ROM, but to no avail (performed a full wipe when going between). Setting the SE Linux Mode to permissive doesn't improve the signal either. I've tested my sim and checked the physical antenna/modem by swapping with another tmobile note 2 but don't see the issue there. => it's isolated to my phone (software related)
I have the following installed:
Android version: 4.3

I'm really frustrated and not sure what to do next. Any help would be grateful! Thanks!!
