[Moto G 2015 Original Android Development] FNetV1:
If by search feature you are referring to network operators where it spends like 1 minute searching and then displays me like 5 options the first one being select automatically, the sprint, then some weird 3 numbers name, followed by At&t and I think t mobile, I obviously tapped on Sprint and after waiting like 1 to 2 minutes it would time out saying failed to register on network, but if I quickly go into airplane mode and then get out it mobile data would connect only briefly like for 3 second and then it would say no service, I quickly go back to the list and select Sprint right away acter turning off Airplane mode and THEN and only then would if finally say Registered on Sprint successfully. But if would still go "no service" figuring oit that it might need a reboot for it to work at this point I went ahead and did just that, I turned the Moto G3 XT1548 off and then back on and the same problem persisted, and I still was not able to access the APN list with the same "not available for this user" error.

Aside from the perpetual "no service" issue there were one more, the white notification light located on the middle of the ear piece remained perpetually, after doing a brief googling I saw others were having this same issue and some said there is a cix for it, but I did not toiched that subject any further until I was able to get mobile data working for the phone first and that was priority and then I would waste my further time dealing with this white light always on problem.

Conclusion: After spending like 12 hours trying to come with a resolution for this problem, the no service problem while completely ignoring the light always on problem and still no progress to be found, still not being able to access the APN list I finally threw the towel and I quit on this ROM. The next ROM I tried was "Orion LP" and I flashed their slim Gapps, on that rom I finally had access to the APN list and fibally was able to get mobile data working and as LTE vut if I joined my wifi access point and then turned off wifi mobile data would turn on but remain with an exclation mark, dame thing would happen if I go Airplane mode and then back to mobile, I would only get mobile data working correctly if I open the APN list and briefly tap on my APN setting (the only one on the list) then if would work again. So Orion LP worked just that it wouldnt activate my APN automatically not even upon reboot, I had to do it manually. After giving this rom like an hour or two I finally ruled that there were a potential APN settings bug of some sort on this rom, gave up on it and went back to the XDA ROM list for my phone model, this time I wanted to try a rooted, deodexed and ziplined stock based rom based on Android 5.1 and I did find a thred that listed a stock based rom exactly how I wanted, rooted (not that it had to be rooted, I could have done it myself if need be thru TWRP), deodexed and zipligned. Once again I had perfect access to the APN settings, after adding and saving my APN settings I quickly and right away had once again full LTE mobile conmectivity and this time it would conmect automatically with no problem when getting into my WIFI and then turning WIFI off and when getting into airplane mode and then leaving airplane mode, it would connect automatically.

Note regarding the ROM that finally works: the thread only had roms for the XT1540 for both versions the one that comes with 1 GB RAM and the one that comes with 2 GB RAM. After doing an XT1540 vs XT1548 side by side comarison for differences in hardware and seeing it was virtually the same with just 1 exeption, the XT1540 comes with 16 gb of internal nand flash memory and my XT1548 comes with just 8 GB I gave myself the go ahead to flash the 1 GB RAM bersion of that rom, and everything works perfectly.

So thats my story only two roms works perfectky for the Data Done Right of this phone, the stock original rom (of course) and this other rooted deodexed rom, thats it so far. Since I do not want to cause any further NAND flash wear flashing more roms I am just going to stay with this and call it a job well done.
