After flashing Synergy yesterday, my phone will randomly completely lose cell reception (Display a circle with a slash through it) for about 20 seconds. I installed the rom after a dalvik cache wipe, factory reset, then a complete format during the installation so I doubt anything went wrong there. It' an ATT model, can I just flash the radio through Odin?
There is your problem. Add At&t apns and it should work.
I'm a rogers user, but I searched and I think this is the proper APN:
LTE:
Name: ATT PTA
APN: pta
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMS port: 80
MCC: 310
MNC: 410
Auth: none
APN type: default,mms,supl,hipri
And HSPA+:
Name: AT&T HSPA+
APN: phone
MCC: 310
MNC: 410
APN type: internet
All other fields blank

I think there's still something wrong, I tried adding LTE (Settings button>New APN) but the screen is still blank.

You should remove your IMEI from your post. You shouldn't post that for others to see, as it could lead to "bad" things.
Right, I figured.
You still helped me to discover the problem
I'm re-flashing Synergy with different settings to see what happens.
Edit:
No difference...

Alright, well, I formatted everything and re-flashed Synergy which gave me access to the APN's, I entered the LTE APN, and now that works. However, whenever the 4G's active, my IMEI shows up as 0's and I can't send or receive texts. This is getting pretty ridiculous.
O-kaaay... Once I made a call it established my IMEI and I can send texts.
