12. Confirmed the APN that I needed was in Settings -> Connections -> Mobile Networks -Access Point Names

- Noted none was selected and I had no data connection, even though Mobile Data was on and wifi was off.

13. Tried to edit the APNs in safe mode but could not.

14. Tried adding the following to /system/build.prop and rebooted to safe mode but no change

ril.sales_code=LOL

ro.csc.sales_code=LOL

(I do not think these settings in build.prop do anything. After I later got data working, I removed them with no change to data connections.)

15. Installed (sideload) my copy of idoneapps (idoneapps.com - paid)

unlocked the phone and changed the CSC to XAS. Rebooted but still could not edit APNs

16. Installed (Play Store) app named Hidden Settings. Opened it and selected the RadioInfo option.

This displays the Device Info page/menu.

- Scroll down to the "Set preferred network type" dropdown, just above the Turn Off Radio Button.

- Used the drop down to select LTE/GSM (auto). App stopped at this point.

- I went back in and the setting LTE/GSM (auto) was properly selected/set.

- Maybe rebooted, not sure. Then noticed I could edit my APNs.

- Selected the RingPlus APN and Rebooted

- Went back into the Hidden Settings app, RadioInfo option and selected preferred network type = LTE/CDMA (auto)

- App stopped again but the setting stayed.

- Maybe rebooted for insurance.

- I had data again. 3G and 4G. Need to test at another location because my signal is weak at home.

Moral to this story is that you can only change the APNs if:

- Preferred Network Type on the Device Info page is changed to GSM or LTE/GSM or something besides CDMA.

-- It does not seem to matter what the Network Mode is here; Settings -> Connections -> Mobile Networks. Mine was usually LTE/3G/2G.

-- I used the Hidden Settings app, RadioInfo option to access the Device Info page. It is sometimes Test Mode or Phone Info in other apps.

Testing:

- Speed test gives appropriate results for 3G (no LTE available at this location)

- Calls in and out work

- SMS does not work. I did not try to find working settings as I use hangouts, which just uses data and works. Since you can edit APNs now (see hidden text), just find working settings and try them.
