Mobile Carrier Settings Workaround - EVO 4G General

I wanted to share a problem I encountered & worked around when flashing custom ROMs. The loss of mobile carrier settings & inability to restore without taking it to my service provider.
Yes, I have read through this forum & other forums extensively to find a amenable solution to no avail.
Possible solutions found were tried to possible extents/applicability but did not work for me: I've done Nandroids & restores, I've used TB to back-up the specific mobile settings & restored, I have looked into an elusive EFS folder (which seems like is GSM specific), I have manually wrote my phone's identity, hardware & software info in the hopes of manually reinputting/restoring (which I have yet to find the app, software or EPST code that allows me to do this...except maybe the cdma workshop which I cannot justify purchasing nor am I willing to "acquire").
This happened two times; once after flashing an AOSP ROM and another time when I updated the PRL.
After flashing the AOSP ROM: after an entire weekend of no phone/data service (wifi worked, cell was otherwise functional) and researching...I took it to my service provider. The technician was unable to execute the EPST codes which was apparently related to restoring the phone to their network. It took multiple technicians and 3.5 hours for them to restore it.
After updating my PRL (by this time, I had switched to a sense-based ROM). I took the phone in the next day & the same technician restored it in less than an hour. Also, the PRL was "downgraded" or reverted to the original PRL.
I have since flashed 2 other sense-based ROMs and have not lost these settings. Otherwise, my Radio, WiMAX, PRI, NV & HBoot versions are all up to date. My PRL apparently can't change for it to work with my provider.
I know it's noobish & lame...but this is my workaround...for now; I only flash sense-based ROMs.
I really liked that AOSP ROM.
Constructive comments appreciated & thanks for reading.

I had something similar occur with my phones. I had trouble first activating a rooted EVO 4G only to find out that the programming menu, EPST settings, had mysteriously disappeared. After searching all over, I found out if I updated the all the radios, combo zip, that it restored the EPST settings and was then able to access the programming menu. Mind you, I had to do all this while chatting with sprint rep trying to activate it.
Once it was activated, it was working fine, then soon after I found out that the 3G connection had stopped working. Now this I found out to be fixed by updating the profile. Because the 3G was down, I had to connect to my wireless router in order to have connectivity. This solved the dropped 3G data connectivity.
But in trying to fix the data, I had since flashed to another ROM to make sure that the data was not broken due to a ROM. I found out that once flashed to another ROM after updating the profile, that NOW I had lost voice. It was as if it had been deactivated. I then went back into the EPST settings and saw that it reverted back to the old user's phone number (MDN) and the MEIN(?, the other number used to activate) was also changed. I was lucky to remembered the latter number because it was only one digit off. So seeing that these were changed, I changed them back, and this restored my voice connection.
This is the first time that I have ever experienced this type of problem with a rooted HTC EVO 4G and I have had this phone since the beginning.
Hope this helped a little. I actually just posted something about this yesterday.

I did not do the updates until after I had my cell restored and then flashed a sense-based ROM. Now, all is updated & in my experience since...radios, PRI, Wimax etc...continue to stay current when I flash a new ROM. For some reason, I don't have to reflash these (I've read some people have/have to).
Because the 3G was down, I had to connect to my wireless router in order to have connectivity. This solved the dropped 3G data connectivity.

Curious...restoring 3G through wifi?

I verified these numbers were all the same prior to and after I had updated the PRL and after the techs restored it. The numbers were all the same with the exception of the PRL.

I actually read your post prior to posting this...but my impression of it at the time was that the change in phone number was the determining variable.
Much thanks for your supportive comments.

[SOLVED]Help please. HLR reload broke my phone.

I already started this at the end of this thread:
http://forum.xda-developers.com/showthread.php?p=1881093#post1881093
but now I'm in real trouble so I'm starting a new thread hoping for help.
I was using 3.16 ROM on my mogul and all seemed fine until today I got an authentication error while voice roaming(edit: I said data roaming initially by accident). I called sprint to get an HLR reload becasue the above thread indicated this was helping people.
My phone quit making calls and quit data connections. Data ended with "cannot connect for unkoww reason". Calls simply disconnecte imediately. I could call *2 though.
Sprint had me rest my phone a few times and the checked the MSN/MSID info (which was fine) and evenutually sugestet I try the official rom (yes I was honest with them). I tried this, flashed 2.17 same deal.. after an hour with a tech he eventually told me the 2.17 is an "upgrade" rom and that it won't overwrite everything and that I should reload the original rom... so I just loaded 2.09.. checked MSN and MSID... in fact checked every setting in the EPST stuff against my touch. Everything is the same... except the security section (which doesn't exist on the touch) had the wrong username was my [email protected]nt... instead of sprint email) and some giberrish for a password.
I'm not sure what this should be, but actually I doubt it's the issue.
I'm stuck though. My phone is effectively bricked(it plays bubble breaker well at least) and I'm at a loss. Please advise if you can.
I just got off the phone with sprint. I have reverted to the 2.09 ROM. With the sprint reps help I did "master reset" which i didn't know existed. This is deeper than both a soft reset and a hard reset. It resets all the EPST data like MDN and MSID. We then set these back to what they should be. But no dice. She told me the phone radio must be broken and claimed that the *2 call uses a different radio. (really? does anyone believe that?) So her advice was to go to the repair center (which is 40 miles from here). OH.. and she put a diferent MSID which I find strange. It's no longer my phone number. I asked her if this was right and she said it probably changed when I asked for the HLR reload but that it was correct... weird. I'm in bad shape.
I called back becuase after forcing the phone to roaming I got an interesting message from verzion sayign they would transfer me to their operator where I could pay money to make a call... doesn't sound like a broken radio to me.
So I told the guy this but this time I got someone who knew what he was doing and before I could finish telling him about it he had it fixed. Aperently there was a setting in there system called HSA_Roaming_only that was set incorrectly and was forcing to try to connect to other networks. He checked it (I think.. or maybe unchecked it..) and voila... after several hours and three roms... it works.
The same thing happened to me when I did an HLR reload. I called sprint and told them my symptoms and they fixed it within 3 minutes. I didnt reinstall anything. You got totally whored by sprint, I feel for you.

Did this allow you to EVDO roam? I cant data roam on EVDO and my girlfriends phone can. She is on the 2.17 official and i am on the 3.17 unofficial.

How do you do a master reset?
In the end I did get everything working again. I did get voice roaming working on 3.16 and I do have 1x roaming. I don't believe I have evdo roaming, but I probably won't know for sure until I go into work tomorrow.
I don't think the master reset was needed in the end.. but I could see that it might help someone someday. There is I think a ##something# code to get to the full epst settings, but I just go to \windows\EPST.lnk (edit: this is wrong.. see my next post)
Run it, select edit.. enter you MSL.. please don't ask how to find it.. search. Then under the menu tab... right soft key there is a reset option that I never noticed before. This will reset all the radio setup options to some default values and will do hard reset... erasing your data as usual. I have no idea where these defaults live on the phone... It seems like some roms end up changing at least the MSID and MDN, but some don't. I don't know what else they might change or how they affect what the defaults are that this resetting does.
In summary to my issue, there were two problems:
1) MSID was changed (during the hlr reload) in sprints system to something other than my phone number, (and now it likes to go back to phone number in my phone during upgrades thus not matching with what sprint has)
2) the HSA_ROAMING_ONLY flag in SPRINT's system (not my phone) was set wrong.

keep us updated on the evdo roaming. this is a big deal to me and i hope this isnt like this in the final version of the rom...
First.. I'm wrong about the reset.. it seems you must do the ##something# to get the epst that has the reset option in the menu tab. Opening through the windows link doesn't give that option. (edit: it's ##786#.. some googling found it.. doesn't seem terribly common information though plus google won't take "##".)
I am not getting evdo roaming and I'm pretty certain there should be verizon evdo coverage here... in fact I occassionally see the evdo symbol briefly when I switched to forced roaming, but it goes away immediately.. I suspect it doesn't authenticate.
Being that verizon seems to have much more evdo coverage than sprint, and that they make like $40 a month off their own customers for access to it(last I checked), it wouldn't be at all surprising if sprint can't pay/provide them enough (with all these sero plans) to get them to allow it. But I speculate.
Did anyone ever have this working? I never did.
well mine wont evdo roam on the new leaked rom. But my girlfriend has the same phone in the same house with the 2.17 rom and can evdo roam just fine... so it is baffling me
Something about the new rom is causing the problem, because having these two phones side by side and them acting differently is strange. mine also roamed fine on evdo before i installed the leaked rom btw
Everything else seems to function as normal, but the no evdo roaming is driving me mad. i really hope this isnt an issue in the official rom when it comes out.
we are also both on sero plans and roaming on alltel towers here.
Masater Reset Code
in order to do a master reset you need your MSL# then type ##MSL# and then you can do the master reset this will reset everything and i mean evereything to factory defaults. you will have to go through the sasme initial setup as when the phone was activated the first time. so make sure you have all your correct MSN/MISD numbers

Hmm .. when I go in there I still do not see where I can do a master reset. All I can do is change the MDN and MSID and then select OK.
Cool. I haven't been able to roam on Verizon's towers since I added the leaked ROM either. If I can manage to get through to tech support (the CSR in chat said she couldn't help me) I will have them reset the HSA flag to allow high speed digital roam.

I'm on sero too, but again it's verizon roaming here.. so may be related to why it never worked for me in the first place. You could dare to just call sprint and ask why it's not working.

This is wrong.. this won't get you there, at least not on my phone.. and actually you DON'T need an MSL... BUT you better have it handy to fix things after you do the reset.
Just do ##786# as I stated above (sorry for the confusion the first time) and then look in the menu soft key.
EDIT: After you do the master reset... then you can do the ##MSL# and fix your MSID and MSN to what they should be.
To neodorian... please read what I wrote... this flag DID NOT do anything for my data roaming (and I am in verizon territority) This didn't even fix the usual voice roaming problem as far as I can tell (that's something else unknown which is fixed by the HLR reload, this only fixed my rather unusual problem where I could ONLY roam... and furthermore had to supply a credit card number to do so! This was something sprint broke for me just because they liked me better than you.
I had the authentication issue on my VZW XV6800 - I called in to tech support and after talking to the first person, and mentioning a HSL reset, she transferred me to level 2. The guy had me do basic troubleshooting, and examined some settings, then had me remove the battery for at least 1 minute. reload phone, try over the air programming, and test calls. all to no avail. he then had me go in and edit the settings using ##778 (VZW default password for editing is 000000) you don't need to use the hex code and program designed to give you the password, especialy since I tried this, and it didn't work.
Anyway, he generated a new A(uthentication) code on his end, had me manually input it, and he also had me change my Home SID/NID. Mine said 30/65535. He said it should be 30748/65535.
I then did another *228 #2 and was now able to make a test call. After hanging up I went back and looked, and the Home SID/NID #1 was 30/65535 again. Not sure if those extra numbers did anything, but the phone got rid of them.
I am able to call out and receive calls now, and the data seems to be zipping right along. When I tested gps last night it had me miles from where I was located.
UPDATE:
GPS seems to be working fine. I'm guessing the tower I was "connecting to" was miles away, since I live at the base of a butte, and have terrible reception. Most likely that WAS the closest tower to where my phone was.

[URGENT] X1 can't find T-mobile signal

I have used my x1 for four months in America with T-mobile. The phone had no problem until yesterday. However, yesterday, the phone began to lose signal and automatically rebooted several times. Then, finally, from the afternoon, the phone totally lost the signal, and kept looking the signal.
I took out my sim card and plugged into another cell phone and it worked. So, I thought it was the problem of the rom. (I was using Touch-IT 4.5) I downloaded the new version of the rom, Touch-IT 5.6, then flashed it. However, it did not solve the problem. So, I flashed with the original SE rom. However, the phone didn't work either.
I contacted T-mobile, and there was not problem on the signal on my region. I thought it might the problem of data plan since I do not use data plan. So I used Advanced config and killed every option for data plan. However, it still does not work. I tried to do settings manually. changing band, carrier, and every possible options, but it does not work.
Interestingly, the phone worked two times today for a short amount of the time. However, after the reset, it is gone. Other than phone function, I do not see any problem.
Even now the phone keeps searching the signal. What can I do? I read another article that is similar to my case, and they say even after changing the sim card, it does not work.
Anyone has the same issue? What can I do? My phone is dead for two days, and it messes up so many things. Please somebody help me.
Have you tried redoing the connection setup?
try clicking on signal antenna then enter settings click on network and manual select your network, will take a few mins to find networks if it connects manualy just select auto again and hopefully it will fix it., worked with mine.
Thank you guys
Thank you guys. Yes, I have tried both of them, but it still does not work.
In Connection setup, I chose United States and T-mobile, and the screen to choose between T-mobile and At&t. I select T-mobile, and click Register. Then, it goes to the searching mode again, and nothing happens.
I assume that somehow, the phone finds networks, since it does show the options to choose (T-mobile, At&t). But something is not right, and it messes the set up. I do not know why.

[Q] Full signal, no data on Liberated

Hello everyone,
I just bought an HTC Aria and immediately installed attn1's ROM. My problem is I lose data connectivity even with full signal; I reset the connection in any way (reboot, cycle through airplane mode, change from GSM to other mode and back) and it will be restored for some time and then be lost again.
I could really, really use some help with this, as I have looked in tons of places before posting here.
Thanks in advance.
After trying everything I called my provider and opened a case. Four hours after this the service estarted working perfectly, though they claim they did nothing.
It was probably that you just needed the correct APN settings. It varies from carrier to carrier, and the ROM's default is set for US locale, (AT&T).

[Help] LS997 rooted, DevDigitel rom not getting any service

Hi,
Hopefully this is the right place to post, as this account is too new to post in the dev thread.
For the past few days i have been on the latest rom from this thread https://forum.xda-developers.com/v20/development/rom-ls997-stock-debloated-su-goodies-t3531923 (version 4.0HHH) but i cant get any service, be it 3g or 4g (Sprint, LS997). I can text and make calls, however. I've tried everything i can think of and have been searching frantically for help. A list of things i have done so far, to no avail:
wipe data and reinstall rom
update prl
change apn
update profile through sprint zone app
use shortcut master to try to change apn
flash different roms, such as the one found in the dirty santa thread, none of which work
activating my phone by dialing ##873283# - after a while it said my phone was activated, restarted, but then no service
I have been using an app to check up on which networks i'm connected to, and it always says eHRPD. I don't think the problem is that there are no towers in range, because my family members all have 4g lte.
At this point i'm really not sure what else i can do, and any help would be greatly appreciated.
edit - for a bit more info, when i go into settings and try to change the apn all the options are grayed out. the options are: internet, ota, pam, and vowifi, with internet being the only one with a selection circle next to it. thats why i used shortcut master, which was suggested in the devdigitel thread. when i access the apn settings through there, it has 3g_apn, internet, pam, ota, vowifi and a bunch of dummies. i can select 3g_apn or internet, but i dont think either of them make a difference. when i try to make new apns they dont save and i cant select them.
edit 2 - I went back and flashed the sprint stock rom from the dirty santa thread (https://www.androidfilehost.com/?fid=385035244224409782) and then reset the network by dialing ##72786#, then activated it again by dialing ##873283#, and after a prl update and profile update (while connected to wifi) i get 3G on and off and i had 4g lte (for the first time in weeks!) today out in the city. I think the coverage by my house just sucks, but its very frustrating nonetheless. still doesnt seem like a permanent fix, because 3g is very spotty and 4g only lasted for a little bit
rowing the same boat
i am stuck in a similar rut myself. have you had any luck with the problem, OP?
after a successful root/unlock of bootloader and running the stock rooted rom for a few days, I decided to take the plunge and install a custom rom, after my desire for V4A got the best of me. having had problems with modem signal quality in the past, I am out of habit continually checking my signal level. Before flashing the custom ROM, my signal was around -70 to -77 db .. immediately after clean flash of custom ROM my signal level dropped to -117 and lower. when I do see something show up, it is a 3g icon, and then only for a faint second or less. have yet to see the 'LTE' icon show.
I have tried ##72786#, ##873283#, updating prl/profile. deleted via fastboot : system, fota, misc. reboots, reflashes dirty and clean.
still, i yield a totally undesirable (read: not there at all) signal. i have been using Samsung telephones since the Transformer days (pre OG galaxy) and in a situation like this, one would typically have a modem file to flash via 0din. Is there an equivalent to this for LG telephones? I admit my noobishness with the way of doing things with LG, but i am not unfamiliar with adb/fastboot/0din.
Could myself and OP somehow inadvertantly disable a few bands on the modem? is this repairable?
i realize its anecdotal, but still, my signal took a header immediately after flash of the new ROM (i am hesitant to name it, in case someone interprets it as casting shade at another. ) Could this be the reason? Am i missing something really friggin stupid?
Have you found a fix? I'm in the exact same boat.
Hi there!
I had a similar issue with my LS997 as well - I went through all the troubleshooting with sprint, did everything that you've done including installing the stock rom. I was never able to fix it on my own - I had to go to the sprint repair center that was in town, and they used LGup to restore my phone to factory.
The issue that I was having, was that I had data, but couldn't place calls or send texts. When I tried to place a call, it would tell me that my phone was not activated. Texts just wouldn't send. I spent the better part of two days scouring everything that I could find on the issue, and couldn't come up with a solution. It repeated the issue on every rom, every update, everything. This is all that worked for me.
I've decided to keep my phone on stock until we can get our hands on LGup and a stock kdz, since that is what will resolve that particular issue.
Did you come clean and tell them it was rooted? I may have to go in the store today and do this. The phone is almost useless at this point since I can't receive/send calls or texts.
I did come clean, but I carry the nice 13 dollar a month insurance on it. Also been a customer for near 4 years so that helps as well - I didn't tell the rep that I was talking too, I told the tech that was working on my phone. It's my experience that reps care, techs do not. Especially if it's that easy to fix, roughly 15 minutes or so.
Sorry to hear you guys are having issues.
It seems a small hanful of users are experiencing some service issues
Have you tried to do ##brand#
And let it re-activate that way?
I never activated my test device prior to dirty santa and have no idea how it acted before root.
But after root ive been 100% Lte or 3g 1x depending on area. I did have issues that after any rom flash i do need to do a profile update or a ##update# to return service
To be honest. Lte isnt provisioned by the device at all. Its only provisioned by the lte sim card.
If you ##data# and hit view is your ptn and msid present?
If not this is why texts wont work
For data. Ive found you can use the shortcut master and access all the bands for our handests without the msl.. I can get the msl for those who dont have but its not needed for this process.
You use the shortcut master lite app from playstore.. Then go to search and search mobile network settings. Or lte.
Make sure its set to cdma/lte
As well have you confirmed under your settings you have a network set to lte/cdma?
This seems to get unchecked sometimes..

I'll give what you suggested a try and report back.
I tried ##brand# and it cleared some settings and rebooted but I still have no network. I did ##data# and went through all the settings and neither ptn or msid are present. Phone is set to CDMA on device settings.
I used Shortcut Master (Lite) and could not find a setting to select CDMA after searching for lte. No search results when I searched for mobile network settings.
To add some information, I live in a very rural area where my phone is always roaming. Today I was in an area where I get LTE so I wiped my phone, flashed the LS997 stock rom and did ##873283#. This enabled data and I got LTE but still no text or voice. I wiped my phone again and flashed your rom, went through the same process and got the exact same results.

see here for walktrough, working on getting a way to write a prl manually now. Found a setting to do it but i cant get it to show the prls i have on my device.

I cannot get LTE to any APN work right with any custom ROM on the Moto G4 Play. :(

I have the Moto G4 Play (XT1607) (Harpia) and I have decided to flash LineageOS (lineage-14.1-20170131-nightly-harpia-signed.zip) on it using TWRP v3.0.2 r5. After getting it installed I noticed that it was not connecting to my 4g LTE Internet (I have Ting). So I figured I needed to make some changes to the APN settings. So I go to Settings>... More> Cellular Networks and the moment I click on "Cellular networks" I get an error message saying "com.android.phone has stopped". After reflashing and trying again a few times with the same result, I tried using a completely different ROM. AOKP. (aokp_harpia_nougat_nightly_2017-01-31.zip) and I ran into the same exact problem I was having with LineageOS.
I then tried to see if I could force my way into the APN configuration using an app called "Change APN". This worked, but now I see the message "Access Point Name settings are not available for this user". I decided to ignore this and click on the + to create a new APN. After filling the correct info out for Ting APN, I click on "Save"... and it doesn't save at all.
I decided to revert to the stock rom, and everything works perfectly fine with the stock rom. 4G LTE on Ting works fine. Whenever I try using a custom ROM of any kind, I run into the problem I described above. I don't know if I am forgetting to do something, or completely doing something wrong. I could use some help with this guys.
Isn't Ting a Sprint service? I didn't think CDMA-based networks had APN settings to configure. Verizon and US Cellular have always used *22XXX for programming, as far as I can remember.

Yes. Ting is a Sprint service. Well either way LTE isn't working and the 3G keeps randomly turning on and off whenever I use a custom ROM. However, when I use Stock firmware, everything works perfectly fine. I am unsure what is causing the issue.
It seems nearly all custom ROMs at this point are having data connectivity issues. I'm trying to find a nandroid of the original xt1607 rom so I can just go back until its all sorted out.

With Ting you can choose to use Sprint or T-Mobile. I am using the T-Mobile side of Ting and you do need to add Ting's APN settings for it to work. I am still on factory ROM but watching closely to see what others are experiencing with custom ROMs.

I haven't noticed any issue with my GSM ting service on lineage. I get LTE and the WiFi/LTE handoff seems to work. I don't install many apps and don't let them run in the background, so perhaps there's a conflict between them that's shutting down LTE service. This is just a guess.
Anyone have any information pertaining to this subject? I've searched hours on hours to no avail. I run U.S. Cellular and on the newest RR-5.8.1-OMS after I go to Settings>More>Cellular Networks>Crash. Every time. Resets my radio and picks right back up again. Everything works until I'm in my house, then I'm roaming and there's no way to manage in settings because of the crash.
I looked around in the file system and in /data/data/com.android.phone/ there is no files, no .db files or anything. I don't know of there's supposed to be either. But like OP stated, stock rom is flawless.
Would I be and to copy com.android.phone from stock and restore after flashing? I don't know what to do but this is with every single custom ROM out right now on every release. Data and everything works fine as far as I can tell but just no way to configure the settings. Any help would be greatly appreciated!!!

Just out of curiosity, have you tried the *22XXX thing yet?
EDIT: Just so we're clear, with you all who have CDMA phones, when you go into "IMEI Information," it does show both an IMEI and an ICCID, right? Because if not, I think I figured out why your LTE isn't working.
I tried, I tried dialing *22999 (guessing that the x stood for the 9 button in T9 language) and pressed the make a call button. Am I wrong about the "XXX" part? Because I did try that when I seen it previously in the thread earlier but had the same thoughts.
So to make that novel a shorter version, what exactly should I dial?

It depends on the carrier and the model of the phone. For most Tracfones, it's *22890. For US Cellular, I've seen it as *228 and *22894. You may have to call your carrier and ask what their phone programming code is.
Aaah ok I got you now. Yes I've tried that on nearly every ROM. Matter of fact I just noticed I posted a little off topic almost, but I'm here for the relevance of com.android.phone crashing EVERY SINGLE TIME I try to open Cellular Networks. The only ROM I will say it doesn't force close on is the Slim Nougat ROM, but I don't run that because instead of Cellular Networks settings making com.android.phone crash its when you place a call and then it force closes the UI part of the call but still carries the call through. I forgot to mention that by the way, whatever it is in Slim that is the making the different reason for force closing com.android.phone could probably be a pretty easy red flag for someone better equipped for this Lind of troubleshooting than myself!
Thank you for the suggestion though on the *22(8 in my case)

After I posted that, I went back to try and see if Lineage was able to pick up my phone's MEID (even though I use a GSM SIM, the MEID is still tied to the phone hardware). For some reason, Lineage is not reading it, and I think all of your problems are being attributed to that fact.
The way CDMA phones work (and god, do I hate this), is your 2G/3G network is tied to the phone MEID, while the LTE SIM is data only. The OS needs to read both the 14-digit MEID (sometimes shows as a 15 digit IMEI where last digit is 0) as well as the 20 digit ICCID (SIM Number). A phone may also use the SIM number itself as an IMEI (BYOP SIMs do this) by dropping the first five digits of the 20 digit SIM number.
If you phone is showing only one 15 digit number in the system settings, then it's either the MEID OR the SIM, not both. So either you have calling and no LTE, or LTE and no calling. You can't program APN settings because the phone has no idea what ID number to tie APN settings to. This is actually a rather serious conundrum.
Ok ok, makes sense. I checked my Status info, every ROM has dual SIM capability by the way so I don't know if that would effect anything for xt-1607, but I looked at SIM slot 1 info and it reads my MEID correctly with 14 digits. I couldn't find anything about ICCID. My head pounding question here though, why in the hell (pardon the language) is everything flawless on stock, but on every ROM this problem occurs? Here's my next killer, everything works like it should for me, LTE, 3G, Calls, SMS/MMS, just can't change any of the settings due to a force close, AND I put my friends Straight Talk SIM in and it fired right up with no force close when going to change Network settings...?!

I think you just answered your own question. As stated in PCMag back in 2015, "Nobody makes a Dual-Sim phone compatible with Sprint or Verizon." It legitimately believes your MEID is a GSM-based IMEI, and is attempting to cross the streams, so to speak. And the only way your friend's StraightTalk SIM would work is if it was piggybacking off ATT or TMo's networks (the MEID would have been paired to the other phone causing a mismatch).
If you look at the stock ROM for this phone, you will see a BUNCH of system apps for programming Sprint and Verizon network information. They never made it into the custom ROMs we're using. FWIW, here's my thoughts on the matter. Someone needs to go back and make a single-SIM variant of these ROMs, as well as a flashable ZIP containing the necessary APKs for Android to detect the necessary information correctly. And if that doesn't happen, then everyone who bought an XT-1607 has to ditch their carrier and move to a GSM carrier.
That makes complete and total sense! Because I wasn't thinking this while time of it but I was in Oklahoma at the time where the main towers are AT&T, matter of fact Sprint and U.S. Cellular lose almost all signal right when you hit the county line where I was at. Verizon only gets signal because it's Verizon, lol. Reason I say that is because I was wondering why this whole time I has full signal with LTE coverage and completely list everything when I went hone, because where I live is complete opposite, there is hardly any GSM coverage, we don't even have an AT&T store, just Verizon, Sprint, USC.
So, with that being figured out, my laptop just recently kicked the bucket on me so I'm out for the most part, I do have a trick to swap files in and out of a compressed archive without extracting it in any way! But, it takes a while, not too much longer I guess but nowvi just remembered everything is pretty much .dat files so nevermind that.
Not that this thread isn't the most popular, but where would be the best place to take this request too to get the most attention from it? I mean if I had to go back to stock, so be it, but I'm a little spoiled to the custom life. Lol.

IIRC, there is a Verizon thread with 80ish replies, but I think a developer like Squid might need to be made aware of this, so I might copy this into the Lineage thread.
A bit of good news. While reflashing all the time that were force closing when opening cellular networks, I looked in /data/data/com.android.phone/ and was looking, now remember to go back to that directory after I say all this, I found that directory was empty, on all of the Roms. Was curious so I flashed back to stock. Went to the same directory, BOOM! com.android.phone was not empty, in that folder I found 2 folders that were now populated with in:
1: (/files/ )I now had a file named carrierconfig-com.android.carrierconfig- (and after the dash was my ICCID number) so for this directory I need /data/data/com.android.phone/files/carrierconfig-com.android.carrierconfig**ICCID** (replace **ICCID** my ICCID number)
2: then there was this /data/data/com.android.phone/shared_prefs/_has_set_default_values.xml
and
phone/shared_prefs/com.android.phone_preferences.xml
These files are missing on all the Roms, I know this doesn't since everything, but I know for almost a fact it's a good chunk of something that needs to be available. Can I copy these files and move them into place, and set permissions how they were? I ran out of time tonight, and am busy all week so this is mainly for reference I guess. More research told me these files can be edited to change what is available to configure in cellular network settings like option to change from 2G, 3G, LTE, APN, and so on. Sorry for the mess, that's all I have for right now.

That is definitely a major find! My only concern is even if you do that, there might be further missing components that would cause Dialer to crash on startup or some other wacky side effect. However, if you can make it work, then it's possible the proper APN settings will load by default and you'll no longer need to change them.
If you can, go into the System Apps on the stock ROM and look for any APKs branded by/with Sprint, VZW or USCellular, or anything CDMA related. They might be necessary for reading the SIM's ICCID.
That's what I was thinking too, and sadly for me I don't really know EVERYTHING to look for so it'll be mostly out of trial and error for me to figure it out. I wish they didn't compress Roms into .dat so I could use a root explorer to swap between tabs rather than copy, flash the rom, paste files and then if that didn't work start all over on restoring stock, so on and so forth. I miss my laptop. =(
Updates?
Has anyone looked into this further? I'm experiencing the same problem with the latest LineageOS nightly. US Cellular Prepaid with an XT1607.
I noticed that in my case i had to skip the Insert Sim thing on 1st boot. It never did whatever it wanted to there. (Maybe because I have no signal or weak roaming where I live?)
I'm seriously considering trying it from an area that I have good service in..
