my phone is unlocked and i use it on cincinnati bell. i understand that these are some sort of certificate files. should i leave these alone or does it matter? ive found 3 instances of these files in /data/misc, /system/etc and /etc. thanks!

Can you be more specific when you say "unlocked"? Do you just mean SIM unlock? Or have you done something else?
If you're still running the stock ROM (which it sounds like you are), then I general do not recommend deleting things because it's not exactly clear whether the phone needs these files in order to work properly. Is there some reason you want to delete these files?

yes i am both sim unlocked and rooted running the stock rom. the reason i am looking to delete these files is to hopefully remedy an issue i have with my data connection. one is (although not really a big deal) the first time i try to access the market after reboot, it kicks my connection. i then have to wait until my connection restores to access the market. im aware of the fact that for you guys on tmo, instead of the link that says "my apps", yours says tmo. after the that initial kick, the market opens up just fine
second, i have shotty data connections when surfing the net, etc. my data connection sends, receives, waits a few seconds, then repeats the process. it takes far too long just to access my google search home page.
im thinking that if i remove these certificate files then the phone wont send requests to tmo, since im on a different network. at this point im just brainstorming because this **** is getting really old. the only way for me to really use my phone is thru wifi, and thats not always available. any thoughts to why my phone might act like this?

Downgraded to RC29, lost internet - Cant' get past sign up.

I was running JF's 1.51 but needed to downgrade to RC29. Now that I've done so I can't get internet and therefore can't get past the sign up stage.
I've searched the forums THOROUGHLY and can't find a solution. Please don't delete my post.
I realize there's a post detailing how to skip this sign in step. Because I can't change the settings of my phone it wont work for me. I need to know if anyone has run into this problem and what are some possible causes. My APN settings are correct. I even have the EDGE network internet icon on the phone, and it looks like there is some activity, but I cannot connect to Google servers.
PLEASE help, I'm kind of new to this and maybe jumped in too quickly, but the first time I followed this process I didn't have any problems at all. I've tried changing the ROM and using different bootloaders, nothing will get past the authentication.
I'm no expert, but just a question. Does it matter if hes using an newer radio on an older build?
When I sometimes flash a ROM and can't get internet access I just turn on/off my phone a time or two and eventually I get internet back.
Actually this is fixed. It was simple and embarrassing.
After doing a lot of reading I found a post on another site with a tmob rep. He was talking about how if you have a shared text plan, sometimes there are issues with the data plan provision dropping off of the sim card because the subscriber will have a shared text plan and also text messages as part of their data package. T-mobile systems see this as redundant and drop a feature.
I've had the same data plan for almost 2 years, it's the same data plan I was using when I first got the g1 - sometimes their systems don't pick it up for awhile apparently - but when they do you can no longer use that internet gateway. Coincidentally, this happened to me just as I was downgrading my g1.
Sorry for the needless post. Thanks to everyone who contributes to the site with guides, they have always been very helpful to me.
Sometimes it's the simplest thing...

Downgraded working G1 to RC29 and can't access Google servers now

I have a T-Mobile US account with unlimited internet access. Currently I am using an HTC Touch Pro2. However, my buddy gave me his G1 to root and sell for him.
I installed RC29 and rebooted the phone. I put my sim card into the G1 so that I could get to the home screen and then begin the process of rooting the phone (i.e. download a telnet client, etc.). Problem is, I get to the Google login screen and it won't connect to the server. I've waited several hours and tried again, thinking maybe the server was down, but still have had no luck. Does anyone know why this would be? Is there another route that I can take (maybe putting a different version on the phone before rooting)?
I could really use the help of some knowledgeable person here.
Bob C.
NOTE: When I'm at the sign-in screen, I can touch the Menu button and get the APN Settings. I noticed one of them is for T-Mobile US, I just don't know what I need to put in each of the fields (if that even will help).
Also, prior to doing the downgrade, the G1 connected to the Google servers fine.
The actual message that I'm getting is, "There is a problem communicating with the Google servers".
I'm at a loss what to do.
i had some issues down grading to rc 29 i few weeks ago i updated to 1.5 and then used the one click root app. and also i was using my gfs old sidekick and data would go in and out all the time and keep getting odd text messages. so maybe ask for friend for his sim and see if that helps.

Is there another version other than rc29 that I can put on my micro sd card and then put it on the phone? It's only since downgrading to rc29 that I have no ability to get past the Google login screen. My sim card, that I am using in the G1, has an unlimited data plan.
I know that unless the phone has root I cannot flash different rom versions on it, but is there a dreaming.nbh file that I can put on the sd card that may provide me with the ability to connect to the Google servers once I install it on the phone (holding in the camera and power button)?
I would give you the link but i am on my phone at work. Search for jesusfreke's thread on how to activate a phone without a data plan. You can use that method to skip the activation screen.
Almost every time I've rooted a phone I've had issues connecting to Google servers. Keep trying. Its taken me 5 or more tries in the past.

I tried over 10 times and even reinstalled rc29. Nothing seems to help.
I also installed the SDK and when I try to start ADB Shell the device isn't found. I think that's because I'm stuck at the signin screen but don't know for sure.
It signed onto the Google server and internet with no problem until I copied the rc29 dreaming.nbh file to the root of the sd card and started the phone via camera/power. It all updates correctly, just can't connect.
It's weird because I used to own a G1 and did the rc29 install and rooted the phone, partitioned the SD card, etc. I have no idea why I'm having such a problem connecting to the Google server.
Any other suggestions?
If no devices pops for adb, then you need to make sure adb is installed correctly.

sorry for the quick information. and you can flash official roms you might want to try updating to 1.5 here is the link http://www.mediafire.com/?zmdyjz3y2zn idk but rc29 was giving me strange issue the last time i had it on my phone so try to avoid it as much as possible now.lol but of you get data on 1.5 download the one click root app and flash cm stable and put cm update on his phone so the next person who gets wont have to worry too much about this root stuff.
i am more than glad to give all the limited knowledge i have but i dont see any advantage of rooting a phone before you sell it just saying. thanks i hope this helps

Okay, I was able to flash 1.5 but I'm still unable to sign-in to the google servers. When I look at the APN settings there is no proxy set, no port set, no mms proxy or port set. I've been searching the forums for T-Mobile U.S. apn settings but can't find them anywhere. Any idea where I can find these. I figure that may be my problem.
Thanks again!
T-Mobile Technical Support's Comments
I have a question about not being able to get connected to Google servers. I still have been trying and trying to signin to my Google account on the G1 that my buddy gave me to sell. I currently have an HTC T-Mobile Touch Pro2 and have been trying to use my sim card in the G1. I phoned technical support today and they guy said that I can't connect because (even though I have an unlimited internet account) my account is setup for the TP2 internet package and not the Google/Android pacakge.
Does it really make a difference? If so, this could be what's causing my problem.

[Q] VIRGIN android user! hi guys!

I didnt see a thread for welcomes..
Hi! i just picked up a sprint lg g2 on a free upgrade but i do not plan on activating it yet since 4g is not currently in my area, so for now i want to use this and just a fun phone for around the house. so i have a few questions after checking out some of the stickys and i dont want to start multiple threads for single questions. if this gets moved to a different area then i understand why as well. also if my typing seems sporadic its because i am coming from a htc tp2 and this is my devirgin process on using androids and rooting. so welcome to my party of self discovery!
1)since i am not activating it can i still pull all the necessary updates for the phone itself off the wifi?
2)in this sticky http://forum.xda-developers.com/showthread.php?t=2479892 i saw no mention of a sprint code. i dont know if i should root it yet because i am currently using a htc touchpro2 im sure the stock speed is going to blow my mind but should i still do that ^^^^ mentioned above?
3)when i got the phone the lady really tried to push the S4 on me saying that the g2 will be stuck on jellybean for 2years? does rooting fix that?
4)when i do decide to activate it, is hotspot easily achieved by an app or is their some kind of rooting that needs to be done? (i already have unlimited data plan)
5)the BB csr also mentioned titanium backup app. and i checked it out and i dont understand how it works. thts for the bloatware stuff right?
6)is it possible to get that flappybird game still? i want to play it see what the fuss is about like on youtube.
i would rather not root my phone if it will stay fast but i dont want all that clutter apps either if its like a new desktop computer that comes with free aol 3.0 and etc.

1) yup
2) I personally dont adjust that simply cause the phone then feels to hot for my liking even though its safe. You can do it and if you dont notice a difference or its to hot for you, just change it back. I think the code for sprint and verizon version is 980? so... 3845#*980#
3)You can root and flash aosp (android open source project) to your phone but you may find that you like the stock software. Also kitkat will be out for our phone shortly
4) You can use a program called foxfi that you can use that will turn your phone into a hotspot and sprint wont be the wiser so you dont have to pay for tethering. Also you dont need root for foxfi.
Just play around with the stock setup and see if you like it, you may not even find the need to root. Also if you enable developer options by going to settings<about phone<software information, and click the "build number" like 6 times (the developer options menu will then be in settings<developer options), you can adjust the window animation/transition animation/animator duration to 0.5 or off to speed up the phones interface.
thanks for the fast replies!
i am trying to update prl/profile/firmware/software etc and it gives me an error. my wifi is connected and i turned off airplane mode for the updates. (i should keep airplane mode on correct so that it doesnt try to activate?)
The dialer code for sprint is 5689#*980#
The prl/profile will only update on an active phone. You have to do it manually if the phone isn't active. That said, you don't need to do it if the phone isn't active, because they are settings sent by Sprint to your phone to let it know about active cell towers and things like that.
Check the Sprint part of these forums. Most of the stuff you asked is in there in one place for another.
Side note, so you don't wonder what is going on. In the title of threads, you will see things like [kernel][rom] etc etc.. things between brackets.. The things that say [INT] stand for International. They are ports made to make the Sprint LG G2 work on GSM networks. If you install one of those rom's the phone will NOT work on Sprint. Right now, that would be no big deal for you, since the phone isn't active. But if/when you activate the phone, you can not use one of those roms and still use the phone as a phone.
should i still update my phone via the LG drivrs at least? also that dialer code does nothing with my phone. it doesnt activate the special menu. so far i havent found it but is their a list of must have apps or a list of minimal steps to get rid of the bloat without rooting? when i am in the settings>>apps menu their is a list of different google' labeled items, are all of those necessary? also someone mentioned foxfi, its only a paid app correct?

[Q] Verizon apps + Root + Move to TMo

I upgraded my unrooted Galaxy S5 to lollipop and it was bad, slow, freezing a lot. I disabled many Verizon-bloatware apps and lollipop is now a buttery smooth beautiful thing!
What pros & cons would rooting a phone generally give me for an average user's experience?
Most importantly, I'm looking to take & convert this S5 phone (and my daughter's Galaxy S3) to T-Mobile this weekend and want to make it all T-Mobile ready. Any insight, thoughts, suggestions, especially if I wanted to root or factory reset my phone but keep app data (such as Kung Fu Pets )?
I've been told by friends and cell providers these phones are already unlocked and can easily switch networks, no worries of voice or data settings on my part, TMo's WiFi calling will work as if I bought the phone from TMo, etc.
Thanks all!

This is my opinion only, with that being said for the average user there is no advantage to being rooted. The average user is not interested in flashing new roms or freezing apps beyond what Verizon allows. The average user wants to turn on their phone and go on their merry way. If something goes wrong they want to call Verizon and have they fix it for them. They would never touch Odin.
With that being said, because your in this forum your more than the average user. If you wan to freeze or uninstall more Verizon/Samsung bloat you need to be rooted.
As for moving to a different carrier I'll let some one who has done that chime in.

Thanks! It won't be a Verizon phone for long, so I guess with rooting it and installing a known stable release be a good idea to get rid of Verizon's bloatware (and maybe some of Samsung's) while keeping a good, hard-working phone? I noticed a big difference disabling what I'm allowed to with Verizon's apps and maybe that's enough, I don't know - any place to research which Verizon and/or Samsung apps are safe to disable (if rooting it & installing a stable release doesn't already remove them)?
Oh, also, is there where I'll go to get future updates since I'll no longer be part of Verizon, and T-Mobile will probably not update my phone since I didn't buy it from them?
Thanks again!
Through a couple phone calls, T-Mobile reassured me both my S3 and S5 would work just fine, everything just the same except I'll have to make sure the phone is unlocked. They also said on both calls that their WiFi calling would most definitely work. Verizon, though a half dozen calls, gave me a different "unlock" story each time. So much for trying to be prepared...
Neither the S3 or the S5 work as expected. The S3 uses the far inferior network speeds and takes about 3 minutes just to send a pic text, and that's only if we're using Hangouts - stock Messages or Verizon's Messages+ don't work on the S3. The S5, I get a lot of "Data (Network) connection lost", setting the time errors, I can't access my voicemail or change my voicemail phone number (not sure if that is a new issue).
So with all this in mind:
1) is the S3 using an inferior data speed network due to hardware limitations or settings I can change?
2) would rooting my S3 and S5 alleviate a lot or all of these issues?
3) any way to get TMo WiFi calling to work on a Verizon phone? Would rooting it allow me to install a TMo version Android?
4) how do I go about updating Android on these phones now that they're off Verizon and not officially TMo phones?
5) any suggestions to fix any or all of these other issues?

1) probably, but I haven't checked the specs.
2) probably not. The APN in your phone needs to be changed to the right settings for your mobile carrier. It's under Settings/More Networks/Mobile Networks. You should be able to google the settings for TMo.
3) The APN may resolve the issue, if the phone allows for it.
4) If you root, you can do it. You may be able to get OTAs with the new sim, but I can't for Consumer Cellular.
5)Again, the APN will solve a lot of issues. The voicemail number needs to be changed to your carrier's voicemail number under Phone Settings.

2 & 3) the APN was already set by the TMo in-store rep, and google search confirms it's the correct setting.
5) voicemail number just won't change! Ug, I've google searched this issue too, no luck, and it seems many Android 5.0 users have this issue unless they factory reset - an option I'm hoping to avoid for a last resort.
I have noticed by disabling Verizon apps, much is working better, but I'm wondering if Verizon made these apps imperative for the system to run properly...?

The only thing I can think of then, is that one or more of the disabled features are required to make things work properly. I would unfreeze the apps and then freeze them, one-by-one to find out which are causing the issues. Other than that, Kies may be able to repair the install if you don't have luck with unfreezing the apps.

Easiest step is to try the enable/disable apps as you suggested. Have you, or anyone out there, tried loading another's stock software onto a phone before doing a factory reset?
See this page: http://www.andromods.com/download-files/tmobile-galaxy-s5-stock-firmware-sm-g900t.html
It gives me the impression all S5's are the same hardware. If that's true, then why can't I install TMo's stock software in the recovery partition, then do a factory reset? (Another worse case scenario, but possibly more of a thorough cure)

If you read toward the end of that post, it says:
Before download check your model number and software version, head to Settings -> About. Confirm that you get the correct firmware that match with the model number of your device, and never use a firmware that isn’t built for your S5, downgrade is also not recommended.

I've also seen a thread talking about doing this for a TMo user on the Verizon S5, but I'm on Consumer Cellular, so I'm not sure if it would really work. Even if it does, I'm not sure if that would solve your issues, and I hear you're risking bricking your phone attempting it.
Not sure if I already mentioned, but sadly a couple T-Mobile reps assured me everything would work great. Not. A factory reset did help a lot, but I keep getting these oddities that TMo is now saying I just have to live with, now that my trial period is over. So any ideas and help would be great!
"Data network unavailable" often appears after a phone call and lasts for a few seconds or longer. In that time, I can't get Maps to find anything, among other issues. This error appears at random times otherwise, but most consistently after a phone call.
"SIM error" happens periodically. I'm not sure the pattern yet, but maybe after a couple phone calls in a row, or call swapping. The only way to fix this is to reboot the phone.
The top status bar bounces between "H+" and "3G". I haven't found a pattern as to when or why, but often can't do much with the phone until it settles down, if it settles down.
Everything I've read and originally heard lead me to believe this S5 should work much better than it is, as if some APN or data setting is wrong. I've triple checked and they seem to be set properly, but I don't know anymore...

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..
