[Samsung Galaxy S 5 Unified Development] Sleepypaanda:
Having a super hard time troubleshooting .. ive spent a few weeks now trying different methods and guides to enable my data on my S5 g900w8 canadian variant ( Bell network ) ... wondering if anybody can give me a hand or let me know if there having the same issue as i cant find a thread for it anywhere .

Problem :

Im running RR N 5.8.3 on my S5 and have no service at all . When i go to "network settings reset" and reset them (WiFi/BT/mobile data) i get service but no LTE/3G/2G . I'm able to make calls and text however I cant get a mobile data connection. WiFi works perfect so I connect to my primary device hot spot (have 7gb and the calls and text work so its kind of okay ) but every time my device restarts or dies and i have to charge it .. it comes back on with no signal and i have to reset the network settings again.. including my password for WiFi.

Whats Weird:

Im connected to bells network when I am able to call and text . Then when i go to network operators it says I'm registered but shows no networks, so i click refresh to search for networks and my network comes up with a sim icon beside it but 2 or 3 other networks do as well and sometimes one of the networks has a check mark beside it as if its connected to that network (not my Bell network, for which my sim card is). When i click my network (which is sometimes listed as "Bell" and sometimes as "BMC") it says "registering on BMC" and then after a minute or two it says "Cant connect to this network please try again later" and then immediately goes to "automatic registration..." where it attempts to auto register for 5 mins and then says "sorry cannot connect to this network at this time please try again later" but the whole time there is a check mark beside my network and sometimes no sim icon . So when reset the network settings again, to enable my signal on bell network for calls and text i go to "NETWORK OPERATORS" in settings and click 'choose automatically' all it says is registered on network with a phone icon beside it then dissapears. SOMETHINGS DOESNT MAKE SENSE.

List of things Ive tried:

1. Reflashing ROM , many times.

2. Changing network mode to wcdma , GSM , LTE onl etc.. (no 2G or 3G networks work either)

3. Waiting 1-2 mins after bootup to unlock device

4. Putting it into Aeroplane mode for a few mins then back off to regular signal

5. Powering off with home button and power and pulling battery and sim and powering on again

6. Smashing my face off the keyboard

7. Throwing it in the lake.

8. Endless youtube and google searches.

9. Manually resetting/adding APNS

10. made sure SIM worked in another device.

11. Registering an account with XDA and trying to follow the rules re: posting and threads of this insanely large community.

If anybody wants to explain the Ariza patch and whether or not i should do that through busybox that would be appreciated, its the only thing i have not tried yet, and its because i read it was to fix null IMEI's that prevent the network from connecting to the device, however i do have some type of service so im not sure if that is the solution im looking for, and when i check settings my IMEI info is still displayed.

If ive posted in the wrong thread please let me know but this was the closest thread i could find to what i was curious about without posting to the same connecivity issues thread that others do . . mainly because i have already spent weeks going through the troubleshooting in those threads. any help at all would be greatly appreciated.

Thanks
