Like most Droid 3 owners I'm sure, I'm tired of paying ~$105 a month for cellphone service through Verizon that I could be paying ~$70 a month for through T-Mobile.
I've read the other thread here associated with unlocking the GSM portion of the Droid 3, but a lot of it seems to be shrouded in maybes and varied successes with a limited pool of test devices to draw on.
From what I gather thus far, the following is true:
- You can unlock the GSM capability of the Droid 3
- You can operate it on T-Mobile
- If you do, you will only get "Edge" connection speeds - No T-Mobile HSPA+ or 3G speeds. "Edge" only, at 512 kb or something like that.
Can anyone confirm this? Is there a way to get a Droid 3 to operate on T-Mobile's network at full speed?
Is there a more reliable and easier to use method to convert a stock VZW Droid 3 to something operable on T-Mobile?
Thanks in advance to anyone who can accurately answer these questions.
The only thing I've seen that works is using the xt883 Chinese ROM and it only gets edge. Edge is fine for me, but I want a better ROM with access to Android market.
Im still learning how this device works; I just installed Safestrap and tried to flash the GSM CM7 ROM today, to no avail. I flashed a custom ROM on my Droid 2 last year, but it's been a while on the G2x which isn't as locked down.
I flashed the CM7 GSM ROM on the safe mode partition, thinking that was how to do it, but I got an error trying to back anything up because /system wouldn't back up. Then when I flashed the ROM it wouldn't boot. Im wondering if I was supposed to flash the ordinary CDMA CM7 first, then use the GSM one, since it's named 3gedit.zip. I haven't tried that yet though, and the fact that /system isn't backing up worries me. I didn't create a partition on internal with Safestrap, but I flashed the GSM CM7 ROM from coreless in safe mode and it wouldn't boot. Got back to non-safe mode and my stock ROM was fine, but I still want to see a good back up :-/
Any ideas from more experienced users would be great. I'm pretty much a blind guinea pig right now lol. I just really want to see CM7 on this D3, and have it work on T-Mobile so I can retire my G2x for a little while.
Thanks in advance

Tutorial
note: This is not tied to any specific rom, it is not using the chinese rom it is simply taking the radio off the chinese rom which is all we need. It hasn't changed anything to me in user space that I have noticed.
I would recommend unlocking, rooting, flashing the radio, and editing the build.prop.
1. Unlock or online sim card unlock code seller but less reliable.
a) Meet the following requirements:
* Must be a Verizon Wireless customer.
* The phone being unlocked must be active on a Verizon Wireless line of service.
* The line of service must be active at least 60 days.
* The line of service must be in good standing for the past 60 days.
* Only one SIM Unlock per line every 10 months.
b) If you don't meet one or more of the above requirements, call anyway. You may still get lucky.
Call 1-800-711-8300 (Verizon Global Support) and ask the representative for a SIM unlock. Occasionally a representative may not know exactly what you are referring to; make sure you are not transferred to a different department. You are in the right place. Explain that they should have a walkthrough on how to do this, and that it allows for the use of local, non-Verizon SIM cards while traveling abroad.
c) Insert a foreign SIM into the SIM card slot on the side of your phone and then enter unlock code.

All you have to do is flash the radio.img from SOLANA_SLNCT-57.1.60_Fastboot in fastboot mode
Code:
moto-fastboot flash radio radio.img
then add the following lines to the build.prop
Code:
persist.ril.rssi.enable.param6 = 1
persist.ril.baudrate=230400
I can confirm this works with an AT&T sim in an unlocked phone, tested with stock and liberty 2.0.

I have called out, received a call and a text, I have checked my account information with the tmobile app on edge. I have been led to believe that its hardware that tmobile can only do edge since they use some non standard bands.

Even if you go through all of that you I'll still have only EDGE because our radios don't use the 700 MHz. Just sell it and get a phone for T-Mobile.

Thanks for replying. That's where I wound up going on my own because I was trying to use his CM7 last night. Can't seem to get it to flash though. Backing up with Safestrap isn't working either...getting an error because /system won't backup for some reason.
I think I'm gonna flash everything back to stock, uninstall Safestrap, and try the above from the beginning. I'd like to see if I can at least get edge and below on T-Mobile using a US ROM.
Thanks again!

So, I have a couple of lines on VZW, but they are all used by family members on my account, and I don't have a VZW SIM. The guy who sold me the phone said he already unlocked it, and I believe him, but is the SIM an issue and is there any way to know if the phone is still unlocked? Can an unlock be undone after wiping internal sd?
I'm asking because I think I can just not worry about that step, but I want to double check. I put it back to stock 2.3.4, now showing 5.6.890 xt862 instead of whatever the xt883 was. I did this to get rid of the previous owner's Google account. Edge, calling and text were working on T-Mo when I bought the D3 a few days ago. When I put my SIM in now, however, and change it to GSM/UMTS mode, there are no operators available when I tap on the list and of course it doesn't work yet. I understand this is due to putting it back on stock lol, but I'm gonna go ahead and try flashing the radio and seeing what happens.
It's already rooted using zergrush. Has safestrap and I can boot into it by rebooting/pressing menu, but my /system folder won't back up. That's the only sign that something is wrong other than the fact that no ROMs will flash in safe mode. I've already left comments on Hash's site, so I'm waiting over there too. Figured I'd pop in here again real quick
Thanks.
UPDATE (from the other forum):
My Droid 3 is working on T-Mobile for voice and text. This is exactly what I wanted. Got some great in-depth help on this one, especially from @tspx23. Thanks a ton! This will be my daily driver now until we switch to VZW, at which point this will turn into a back up, unless I fail to find something else worth a contract at that point lol.
I might write a guide later on if anyone wants it. The process is easier than it seems, as long as you have it in plain english lol.
Thanks to anyone who contributed to this!
Is it possible to mix this with a current rom instead of flashing a random Chinese one, like infuse with cm7 or liberty?
Tmo has horrible coverage and awful customer service. Cs is all nice to you but lies about everything constantly. They did nothing but screw me. That's the whole reason I'm on verizon now. At least now I have coverage and won't be lied to whether or not I have it, or be told to get wifi and then u can make calls since u don't have service.
Sent from my DROID3 using xda premium
I don't know of anyway besides a sim card to check if its unlocked and I am not sure a verizon one would ask for the sim unlock code even if it was locked but sim cards can be really cheap. If your phone was unlocked that will never be undone, if it was working on tmobile before you reverted to stock then it is unlocked, it would not have worked using tmobile otherwise.
are you using the latest version of safestrap, he released a bugfix version pretty recently? Could you be more descriptive of what you did while in safestrap?
It is not rom specific as far as I know, I am just using the stock one.
@Darksurf, I agree. I never had them but before I moved they didn't cover my old town. Verizon may be expensive but at least they tell you they will rape you at front and explain all charges.

you can also try with at&t in full3g. As they have the same bands the d3 has
Enviado desde mi DROID3 usando Tapatalk
I will see tomorrow if this works with ICS
Radio and build prop edit
I'm staying on T-Mo till they go under. They are cheap and I have unlimited Edge, which is all I can get on this phone anyway lol. Only ten bucks a month for data, since I have an older package from before they tried to hike their rates.
My D3 is having some issues after I reboot, and sometimes just randomly, it will lose all signal and tell me that my preferred operator cannot be found or error connecting. I have been just rebooting and sometimes wiggling my SIM around to see if it fixes, and it does.
Only other thing that is a little weird is my phone thinks it's an xt883, even though I'm on the stock VZW ROM. I'm wondering if this is causing some issues that I'm not qualified to really diagnose lol. Usually after I reboot, I have some of my google apps' names in Chinese, but I'm not sure if that is from radio.img, new build.prop, or from changing my bloatware to .bak.
Also, be advised that if you remove bloat, conversations.apk breaks incoming text if it isn't seen by the system. I added .bak to the end of it and could send texts to my wife, but couldn't get any messages. I changed it back and texting works fine. I use Chomp SMS, but that didn't seem to matter.
Have fun
P/S: also, when choosing operators in settings, you have the option for T-Mobile 2G, AT&T 2G or 3G. Just to confirm ;-) probably because AT&T's 3G bands are the international standard, right?
when you flashed the stock rom back onto it did you delete the /system partition and do a factory reset on your device before you did it?

I'd love to see someone put these mods into a ROM, but I'm not sure if any of it is compatible with existing ROMs. I also accomplished this on stock. When I get around to flashing CM7 again (or trying to at least lol), I'll post about how it goes.
I'm thinking that when I wiped my phone, the unlock remained but the radio.img that was on the Chinese ROM was undone or lost. Flashing it was easy though, using cmd mentioned earlier in this thread. I just needed help figuring out how to set it up, since I'm a noob at command line lol.
After that, I downloaded adb and tried to use other commands I've found (which claimed to work, but didn't for me somehow) to change out the build.prop. This failure was likely my fault lol but I found it easier to just use Root Browser lite to back up my original build.prop then replace it with the modified one.
I figure that if my SIM doesn't work after flashing some other ROM, I'll just try the two main steps again and see if it works then. If anyone really wants to do this, it isn't too hard or not worth it in my mind. I also figure this phone will be relevant enough for a while longer, considering I am cool with Edge speeds, I certainly won't mind being stuck with VZW's 3G whenever we change over. I am in no hurry to get LTE battery suck or bulkiness either. I'll wait for a little more refining to be done on that end before I upgrade from this phone
I am interested in making the phone compatible on T-Mobile / ATT by flashing XT883 radio. I have one question: Will the "unlocking" turn the phone completely GSM phone so it can no longer work on CDMA network?
Thanks.
Probably until you flash the Verizon ROM back I would assume.
Sent from my XT862 using XDA App
No. XT883 is also CDMA compatible, so the ability to use CDMA should stay. You might need to do *228 though.
You unlock the phone via carrier unlock code, e.g. they give you a code via email or over the phone allowing your gsm functions to work with foreign sim cards (other than the one they come with). After getting the unlock code and flashing the xt883 radio.img (and changing/replacing your build.prop) you can still choose to use cdma. Flashing this radio (which I'm currently using on T-Mobile) doesn't make your phone incompatible with cdma and is reversible. You would simply have to flash the original radio.img and change back your build.prop, or just flash a regular cdma ROM. I plan to do this some time next year if/when T-Mobile goes under and my wife and I switch to Verizon. In the mean time, I only get edge on T-Mobile (using it on AT&T will get 3g), but I have cheap and unlimited data (legacy data plan $10) and a great phone with keyboard. I'm using the stock ROM, rooted, but will eventually try CM7 with the gsm tweak. I will likely have to reflash the xt883 radio.img and change my build.prop (I think).

I have tried to search the forums for answers, but I keep finding a lot of non-definitive results (and many reference FAQs for the Galaxy S phone).
I have a T-Mobile Galaxy tab that is running stock T-Mobile Firmware. I also have an active AT&T SIM card via my job.
I have unlocked my tab and created a custom APN that allows me to use the AT&T SIM on EDGE.
I understand that AT&T and T-Mobile use different frequency bands for their 3G, but I am unsure if these frequencies are completely unavailable on opposing characters or if they are just disabled in firmware/software.
Is there a modem.bin (or other firmware) that will allow we to flash a T-Mobile Galaxy Tab and use an AT&T SIM for 3G? If so, is there a firmware to revert it back if there are issues?
I don't really care about voice (at the moment) but it would be nice to use the unlimited AT&T 3G card instead of paying month-to-month with T-Mobile.
Why dont you unlock and try? I know rotohammer posted instructions on how to unlock. He also posted a complete package to flash to stock.
NO, it's not possible!

If you're willing to test it, please let us know how it goes! I'm interested, but I'm scared that AT&T will screw up my current plan. They've done it before - swapped from iPhone 3GS to Palm Pre Plus, then back to iPhone 3GS - found out they switched to unlimited data, and didn't work on my iPhone. I had to call to have them switch back to an iPhone data plan.
Also scary - stuck a dumb phone SIM into my iPhone -automatically added iPhone data plan.
I'm grandfathered into the unlimited iPhone data plan, and don't want to risk it.

You can create a custom APN profile and use almost any AT&T SIM in an iPhone. Get on WiFi with your iPhone, and open http://www.unlockit.co.nz/.
My AT&T work SIM is for a blackberry, but I have been using it with my current and prior iPhones with no issues (I have helped a few others in my office do this as well).
I am hoping to be able to do the same with my Galaxy Tab.
Thanks for the link. I will try the modem.bin in a bit- and may even go and do a full-blown AT&T firmware at one point-but I am trying to make sure I have a chance (i.e. the radio frequencies are available) and a way to backout if there are issues.

The thing that scares me is that AT&T actually messes with your plans according to the device you stick your SIM in. Now that's BS, because if I ever want to stick it in another phone to test it out, then put it back in my iPhone, I may loose my unlimited data plan and end up with the 5GB data plan. They don't offer unlimited anymore. I'm grandfathered in.
Before they took it out, I was able to swap devices willy nilly. They were able to switch from plan-t0-plan, and I don't care because I can always get back to the plan I wanted. Not any more!
Let me know how it goes. I'm interested in flashing mine, but not sure how to go about it.
Well, curiosity got the best of me, and I put in my iPhone 4 SIM into the Tmo Tab. It works! Just make sure you have the APN set up correctly. Edge only. I have no idea how to flash the modem.bin file. I'd like to find a way to back up my Tmo modem.bin first before I try the AT&T one.
Nope I've tried *#2263# and changing the apn modem.bin still got edge.
I went ahead and tried a few things- and here is what happened.
I flashed with the EU firmware and the Bell Modem (via the RU firmware and repartitioning) and ended up only getting a GSM signal (wow- that make me nostalgic of my old Nokia 3650 days).
I messed with it for a while and eventually flashed the AT&T stock firmware. With this I was able to get EDGE, but the whole system was buggy- such as the startup screen was blank until it completed and I pressed the power button.
I trief to re-flash with T-Mobile stock firmware and I was stuck in EDGE; no 3G available.
I tried to re-flash with T-Mobile stock again and I totally bricked the unit (note: don't rename the folder containing the firmware while you are in the process of flashing!). It was uber-dead; it wouldn't power on, no recovery mode, connecting to a PC didn't detect any device and the charger wouldn't even light up when I plugged it in.
I ended up returning it to T-Mobile as I had only had it for about a week. They gave me a credit minus a $10 restocking (called post activation) fee. I may look around to see if I can find an AT&T Samsung after the holidays...

Ouch! yea, you wouldn't want to change the name of the folder you're flashing from. >_<
For those who flashed their Tmo Tabs wth the AT&T modem.bin file and still getting only Edge, did you make sure you're set to connect to GSM and WCDMA?
When I inserted my Tmo SIM back in after playing around with AT&T, I also had Edge only. I found out that I left it on GSM only. Doh! Set it back to GSM and WCDMA, and I got my 3G back.
I'm hoping that's the small detail that is preventing Tmo Tab users who flashed to the AT&T modem.bin.
I still haven't found the instructions to flash the modem.bin though. All the guides I found are about flashing entire ROMs with the modem.bin, not just the modem.bin itself with the stock (but rooted) Tmo ROM. Otherwise, I'd try it myself. Also would like to know how to back up my current modem.bin before I start experimenting.
On a positive note, AT&T hasn't messed with my granfathered unlimited iPhone data plan yet. *cross fingers* Makes me feel more confident to try it again on my Tmo Tab.
Has anyone succeeded in getting both data and voice? I have an iphone unlimited data plan and a t-mo tab.
Where are you guys getting the ATT rom from and what .pit file are you using.
I am trying to go back to the ATT rom but it boots blank after trying a couple posted here.
Thanks
I too have a tmobile SGT and I would very much like to use it on at&t 3g. I have sadly yet to have found a definitive answer as to whether or not the hardware is capable of doing so? Shouldn't it be a simple matter of flashing the at&t modem.bin onto the tab so that it can handle the appropriate 3g frequencies?
please advise!
Definitely NO. Hardware is not compatable. There are many definite answers, and a few idiots. The radio frequencies don't match, and no rom or modem file can change that.
Hi Everyone,
I'm not sure how to try this out, since I'm not in the US, and that RadioComm doesn't work for my Droid 4 (it's been upgraded to ICS)
1) Install latest Motorola drivers and RadioComm
2) Launch RadioComm
3) When it RadioComm launches, Click Main -> MA -> Common -> MDM 6x00
4) Click Settings -> USB -> PST USB
5) Click on FTM Common 1
6) Connect the phone to the PC and wait for it to go green
7) Under NVAccess, find the following values:
4870, NV_GSM_850_CARRIER_SUPPRESSION_I
4871, NV_GSM_DCS_CARRIER_SUPPRESSION_I
4872, NV_GSM_1900_CARRIER_SUPPRESSION_I
8) For each value, press Read, then replace all of the numbers with 0. Once done, press write. Repeat for all 3 values/
Let me know if this works!
Again, I mentioned a problem with RadioComm. I'm using Windows 8 x64, RadioComm worked fine with my Bionic on GB, maybe it's an ICS thing, maybe I need newer drivers, etc... Please let me know if this works!
I was able to get this going on my Droid Bionic (which also had a corrupted IMEI number) so if you want to see that post, view it here :

This looks awesome -- I saw your post in the Bionic forum. I was curious if this worked for anyone in the states on T-Mobile? I was looking to get a Droid 4 and use it on Straight Talk. Currently have an Epic, but loved my OG Droid. 3G is fine enough for me -- just curious if anyone is also able to get MMS working as well, along with APN settings?
What version of RadioComm do you recommend? I've tried 11.9.0 and I get the error when I try to open it:
"Error in getting the pointer to CommP2K and/or CommQC. Error number: Exception of type 'System.Exception' was thrown."
If you can help me get past this error, I'd love to try this out...

I'm using 11.12.2, and try to get the latest motorola phone drivers (different than the USB drivers) I think I'm running 5.9 of those.

Awesome, I'll give it a shot when I get home. Out of curiosity -- I'm assuming this is similar to QPST. If I bork the modem, I should be able to go back to a prior group of settings, right?
SIM Card should be coming in on Saturday or Monday -- so should be able to get some news to everyone by then.

Cool, just to give you a heads up, someone tried it in the RAZR forum without success....

Shoot. I've read that you can get 3G on AT&T without any problems across forums -- did I misread and this was for international use -- not inside the US? I just want to get 3G on AT&T if possible...
Any thoughts? Or can you point me in the right direction?

Still trying to figure it out... I don't think we have a solution just yet.
I'm a developer outside of all of this (C# primarily these days, but have an extensive background in C/C++) -- and I've flashed phones to cricket with QPST -- so maybe I can help you guys out with this. If you're up for discussing any background that might catch me up to speed on this (already have my phone), would be up for trying to help break into it and enable this. Just send me a PM if you're up for this. Thank you!
Hey all,
I've only used this program for a little bit but I was able to change the values to what the OP suggested however, I used the Motorola Factory USB cable. I couldn't get the program to recognize my phone w/o it.
I'm using stock rooted ICS too.

So, you updated it with that -- were you successful and does GSM now work in the US?
Did anything change?
Phone doesn't make calls now
I followed the steps above
Radio Comm v11.12.2
Motorola drivers 2.2.28
Whatever data card drivers came with radiocomm
This did not allow me to see t-mobile or at&t here in the states.
So, random question/thought... If we find another modem with similar chip in another phone -- say on AT&T -- would we be able to read some of these fields and stuff out -- and then push it into our modem?
it would be great if we can set the phone to just swap SIM cards very easily, especially in the US

Hmm, might be an idea. I don't think that there were many AT&T phones with this capability though. My idea is to compare an XT910 vs an XT912, since that was a worldwide release.
Best idea, get an XT910, put your SIM into it, grab a full radio dump, then put your SIM into the XT912 that doesn't work and grab another full radio dump and compare the two.
You'd need an internation XT910, since AT&T didn't ship them down there, but that would be a great starting place...

Only thing is that I'd have to go out of my way to do that and spend even more money. I just dropped some on the Droid 4 for an off-contract phone. I wonder if there's any way we could ping some of the other forums, i.e. the Razr and see if anyone can potentially get us full-reads, so that way we could compare/diff them?
In addition -- I wonder if it's possible (probably a long-shot) to potentially order a SIM card or something from another carrier in Europe or somewhere outside the US and get it into the phone, but then have it "added" or "roaming" on a US network or something -- if that might provide a workaround?
Just trying to take stabs at it. I figure I'll hold onto the D4 for another month and see if we have any exciting developments -- and if not -- just push it to Swappa.
So i could use this to unlock the radio for overseas teleco use?

Not sure what you a proposing in your second paragraph. I have a UK SIM card, and when I plug it in two other phones (Samsung Renown, a CMDA/GSM basic phone) and a Motorola quad-band GSM phone, it works fine in the US. When I move the SIM into my Droid 4, no signal, although it sometimes gives the Unrecognized SIM message. So it's not a matter of non-US sims.

I get the unrecognized SIM message also. That doesn't affect the phone one bit though, since I just press okay to the message and the phone connects to my carrier. Is your carrier one with a Verizon roaming agreement?

For just one post that a lot a stuff well anyways, one problem I see is that on the XT860 rom it doesn´t read the SIM ID but on the XT862 it does. Since in my stupidity something tells me that that maybe related to the fact that is not reading the sim properly, I guess I will go into that route to find out what´s happening.
Just a quick update for ya.
Just installed minimoto version of the XT860 into my XT862 and it worked, the only problem is that it says invalid sim, but interestingly I can receive and make calls, signal indicator works better also. Anyways, I will try to find out how to get the rom to detect the sim correctly later.

Re phrasing the question, is there a way to make an xt862 into an xt860, since they are technically the same phone, just with different radios. What I want is to maybe use the phone.apk from the xt860 (that is only gsm/utms) into the xt862, in that way the phone won´t be looking for CDMA settings.
Is that possible?

Hi guys, I already searched on google, on xda, on droidforums and I haven´t found a way to disable the Global mode and CDMA mode, because in my country we don´t use CDMA anymore just GSM (GSM with sim card).(since 1990 something, the whole country moved to GSM).
I want my Droid 3 to just have the option between 2G and 3G (that would be Edge and 3G here), the only option I need would be GSM/UMTS. the other 2 options are CDMA and Global and I want to get rid of them.
Also because for some reason in some areas if I am in 3G and I get a call, the call will drop after making some weird sounds and I will get no signal for some minutes, and I will have to manually go into airplane mode and then out to get a signal again.
So I think, since the phone has this global mode thing, I though what the hell, let´s just disable the global mode and cdma mode and that will fix it. I mean, I believe that the phone instead of falling back to gsm mode (from 3G in lower signal areas) it goes directly to global mode, or even CDMA.
For more info, my phone is a Droid 3 XT862, from Verizon, unlocked and brought overseas, using the latest minimoto rom (I wanted something light so minimoto looked good).
I already applied some build.prop fixes and they worked but the ultimate fix would be to disable global and cdma mode.
Is it possible?

I was wondering if this is possible too, I know there is a line in the build prop that sets gsm to default, but it seems that my droid 3 will change that setting once in a while.
I, too, would like a permanent fix for this.
I do not use Minimoto, but I do use the XT883 radio. I have zero idea how I did it, but my Stock rom (I use SS) does NOT have the network choice. I assume this is what you were aiming for. It only shows the GSM options (2g/3g/auto toggle, Operator select, and APNs menu) and nothing for CDMA. Effectively making my Stock rom GSM only like the XT860. SIM reads fine, calls/text/data all work, no invalid SIM reading anywhere.
I've attached a couple screenshots to showcase this (if it's what you want) and my modified build.prop (incase this is actually what caused it). I've no idea what I've done to the build.prop, I've gone through and randomly changed things in my adventure of doing GSM tweaks, and I mainly use Maverick so my main modifications (that I remember) are there. Use at your own risk, though I doubt it'll do any harm (remove the .txt from the end and make sure you have proper permissions). Remember to backup your originals.
Interestingly enough im having the opposite problem on my XT862. I flashed Minimoto 1.7 to it and I get the "Invalid SIM, 911 calls only" message. Which is weird since my phone works off of CDMA. Anyone else have a clue to remedy this?
I tried your build.prop on the stock ROM with the xt883 radio, but after setting permissions and rebooting, I still have the CDMA network options present, plus the occasional "switch to global" prompt.

I have the 862 with the 883 radio and occasionally my phone will lose the cdma/global options entirely but then after a reboot they willl randomly reappear. The first time this happened I thought it was great lol cuz I don't need them anyways but then the box that normally pops up if you lose gsm signal asking you to switch to global popped up but said "no cdma signal detected, switching to gsm/umts mode" which is exactly the opposite of what it normally says. Kinda weird and I have no idea what would cause it since I'm using the build.prop found in the diy thread with no other changes that I would assume many others are using.

My phone out of nowhere started doing this really fun thing where it drops to roaming at random. From what I can tell, the phone is not making a handoff to the next tower to avoid the roaming. For example, if I'm sitting under a tower with full 4G, everything is fine. If I have 2 bars, it will work in 4G for a while before dropping to 3G roaming. I am able to force it back into 4G by dropping in and out of Airplane mode.
I'm running the official CM11 4/30 nightly (I was on the March Snapshot until this started happening).
First I used some Google-Fu and found it's most likely a bad SIM. I swapped SIMs with my wife, she was stuck in 3G roaming, awesome! Went to Verizon, the switched the SIM, all good, right? Nope, I didn't notice it right away, left the store and thought all was good until I needed to use internet at work.
Next, I thought it was software, so I created a backup, and dirty installed the newest CM11 nightly. No change, so I did a full wipe and install. No luck.
So next I thought maybe the radio was corrupted, so I tried to update the radio, which didn't go so well. I got stuck in a boot loop and had to sideload the old driver and reflash. So I'm back up but still having this problem. I'm thinking my only thing I can do at this point is to go to stock and see if the updated radios make a difference.
I saw another guy is had the same problem, but he had his phone replaced. I'm not sure if that will work for me since I purchased via Swappa (I do have Asurion insurance though).
So what help do I need?
1) Does anyone have any ideas on what I can do to fix this?
2) Are there any good instructions out there for how to flash to stock?*
3) Are there any good instructions on how to re-root and flash back to a custom ROM once taking the newest OTA?*
*Most of the instructions I've found have been pretty confusing and use a lot of acronyms without explaining them. I'd be willing to write some cleaner instructions for a sticky if someone would be willing to help me out with any questions I have.
Thanks everyone, I appreciate any help offered.

I'm fairly certain it's hardware. I spent a day using my Galaxy Nexus - full 4G the entire day.
I went back to stock, "bricked" my phone about 3 times doing it (quotes because it was salvageable, but I had a couple hours where I was googling like a madman worried I dun ****ed up). Stock and the new radios made no difference. In fact, with stock it would only go to 4G if I restarted it - airplane wouldn't even bring 4G back. Figure that one out.
I went to the VZW store and I'm basically screwed. I can call LG and see if they'll replace it or use Asurion. Since I got the device off Swappa, they cannot replace it. They tried to order me a new one, but the system wouldn't let them. I don't really have time to call LG, so I'm probably going to Asurion it. Their process is stupid simple to do and they'll have a phone to me the next day. Then I can spend all day tinkering with it and getting CM11 back on, which I feel like I'm an expert at right now.
Sorry, wish I had better news. If you got the device from VZW, go to the store after flashing to stock. They might want to try swapping your SIM first though, so make sure you go to a store that has decent 4G coverage in its surrounding area.

Thanks dude. I think you are right, flash stock and get a new sim first. I have a hard time believing its a hardware problem. I just wrote this in the other post about roaming:
"Same exact problem here. I was on the phone with Verizon last night. I was running cloudy pro 2 (all his roms for that matter as they are international roms) and kept getting the roaming issue you speak of...with 3g. I went back to 11A completely bone stock. Just like you mentioned, I get 4g but then after like 10 minutes I get 3g with roaming. Of course this is after I spent 30 minutes on the phone with tech support. They 'zapped' my sim card and it appeared to work but no dice. Now before doing all this I downloaded build prop editor and changed the ro.build.target_country to US versus COM as everyone suggested in all the forums, still no dice. I've tried the toggle airplane mode trick...works for like 5 minutes and back to 3g roaming. I think maybe a new sim card and avoid international roms...bummer because cloudys roms are blistering fast. Interesting thing though, I installed xdabebbs rom and malladus' rom, after already running cloudys roms, and get 3g but no roaming. I also verified that Verizon wasn't throttling me or something like that. One more thing I tried is reflashing the basebands and 24A modem, no dice. If there is a build prop fix or some other fix I'd love to hear it.
Edit: One think I'd like to mention. When I had an S4 I switched between stock roms and AOSP roms and the network settings were responsible for causing the roaming because the stock rom was an older build than the AOSP. So when I had roaming, I'd reflashed the AOSP rom, changed the settings then flash the stock rom. It worked great. "
Edit#2: Ok making a little progress. Just did this:
Get a build.prop editor from the play store, and change ro.carrier to VZW and ro.build.target_operator to VZW and ro.build.target_country to US.
Initially it worked but when I make calls it gives me Unfortunately, the process com.android.phone has stopped and I cant make calls. I went into Settings, Apps, reset app preferences...that didn't fix it either.
4G/LTE is pretty solid now but again, I cant make calls.
Edit#3: Nevermind...roaming again.

Alright, so, I have some interesting news.
I got a replacement device from Asurion - not just a replacement, a brand new device out of the box. I pulled it out of the box, swapped the SIM, same exact issue .
I went to Verizon and *****ed up a storm. They basically said "you bought it on eBay, not our problem" (I actually did Swappa - but they don't know Swappa and they do know eBay).
So I got the guy in the store to do some digging, and apparently Verizon has a point opened up with LG as they're seeing this on more and more devices - especially since KK came out. So I figured I could try an older radio. The device was on 12B when it arrived. I just flashed stock to 10B and it's the same issue. I don't know what's going on at this point - nothing makes sense but its apparently a known issue that's been appearing since the KK update.
I'm going to call Asurion and request a new device again since this one is doing the same thing, we'll see what happens. I'm still leaning towards hardware and thinking there was a slew of bad radios that went out.
Just for giggles - and I have no reason whatsoever to think this will work. I'm going to swap out the new SIM that came with the phone. Originally, I just put in my old SIM since the new one was taking too long to activate. I'm having the exact same issue I had previously. With that, I'm going to leave the new SIM in and see if it has the same dropping issue. The guy in the store had mentioned he could swap out the SIM but after a few days it will crap out again... which makes zero ****ing sense. Because of that, I might as well see what happens if I pop a new SIM in. While again, this makes 0 sense, I'm wondering if maybe the phone is frying the SIM somehow?
Again, it makes no sense at all, but I have nothing else left to try other than getting Asurion to repeatedly send me phones until I find one that works or they replace for another type of phone (which I REALLY don't want). I'll drop an edit in an hour or so if what I try makes a difference.
Quick Edit:
I COULD just keep going to the VZW store and have them repeatedly swap out SIMs since it will fix it for a few days .
EDIT:
Got the new SIM installed and it's working. The guy in the VZW store told me that we can keep swapping SIMs and the same issue will happen, which again, makes no sense to me. I'm at a bit of a loss to be honest. I wonder if it's possible that my old device was frying the SIMs (again, makes no sense) and that maybe the new SIM not going in my old device will fix the issue.
What ROMs are you running? A phone frying a Sim does not sound likely at all. I got my new sim card and have been running xdabebbs ROM with no network issues. I feel like my issues stemmed from the Intl ROMs.

The only ROM I've ever run was CM11.
Same thing happened on stock though after flashing through the LG Flash Tool. Then, with the new phone from Asurion, used old SIM - 3G only. Used new SIM - 4G sticks.
So, I've recently rooted and unlocked my device and I wanted to know if I can bring it to another carrier and still get data.? I'm using the LS991 Sprint version. I also wanted to know if there are any good CDMA Workshop alternatives; it's really expensive and I'm only gonna be using on a few devices.
Dfs
So you rooted (doesn't really matter with respect to carrier support) and you unlocked it (that's what matters with respect to carrier support) - so you put in a SIM card for the carrier you want, set the APN data (use Shortcut Master if needed, there's a version specifically modded for the LS991 directly available in my post HERE - might be a good idea to read that post as well since that's what I did myself.
Worse comes to worse if you have no luck because you unlocked your LS991, consider installing the global LS991 ROM (whether it's Lollipop ZV6 or Marshmallow ZV9 or ZVA - if you install ZVB you can never go back to anything prior so be aware of that) which will work much better for other carriers than using the unlock mod so many of us have done in the past.
Hindsight being what it is, if I knew about the global ROM when I got this G4 recently I wouldn't have mucked around with all the unlocking crap and the carrier partition at all for any reason because just installing the global ROM (or modifying build.prop to allow for global unlocked operation) is way more useful and less damaging to the phone. Modifying the build.prop isn't necessarily a cakewalk but, since someone else has already done it for others and posted the global ROM(s) for Lollipop and Marshmallow (as .img files you flash using the Send_Command.exe/dd method) it's really not a big thing anymore.
If you muck up flashing an .img file you can typically just use LGUP and a TOT file to get things working again so it's relatively safe overall, but if you muck up the unlock and trash the carrier partition content the phone will end up being pretty much useless unless you have that information safely backed up someplace (I'd say multiple backups in multiple locations, to be honest).
Anyway, if you truly want the phone to be capable of working on other carriers, my suggestion is go for the global ROM but that's just my own personal opinion on the matter. I'm using tabp0le's MellowMallow ZVB global ROM on my LS991 and T-Mobile LTE works just fine for me, for the record. It did take a little work - I wrote about how I got the full phone/data working in that post with Shortcut Master - but it does work.
Thanks for the help!
One last question, how did you get other carriers to let you activate the phone? Everytime I try they ask me imei then tell me my phone won't work on their network.
Well I've had service with T-Mobile in the past (not currently but will again soon), I have a bunch of T-Mobile microSIM cards because whenever they put the SIM card activation kits on sale for $.99 or sometimes even free (rare but it happens) I usually grab 3 at a time so I have 'em around for testing purposes. T-Mobile doesn't require me to provide any info to them, and even if I go to their website right now and input my IMEI number it'll say it's not recognized, etc but it's not relevant: it works, and that's what matters.
Most carriers don't actually require you to provide the IMEI for any reason as long as you can get one of their microSIM cards (or nanoSIM with adapter) and then get service without having to contact them. T-Mobile is somewhat unique in that process I suppose. With this SIM card I have (it's never been activated) I can go to their website and sign up for service right now and it'll be active in 10 minutes or less, sometimes when I've activated service (it's prepaid so I don't necessarily keep it month to month, sometimes I choose some other service for testing) it's done before I even sign out of their website, like 30 seconds or less and wham, the phone beeps telling me service is working.
So, the advice is: get a SIM card for the phone from the carrier you're interested in and go from there, not sure what else to suggest honestly.

You good sir are a god among men, phone and data are working like a charm. Now I can tell sprint to go **** themselves!
glad it worked for you. MY experiences with ls991, i am using it nvmode. zv6 rooted works for me with cdma data. but data doesnt work with zv9 or zva. global rom doesnt work unless, I edit build.prop target carrier to SPR . it is open to use it as global mode. I am using it in cdma nv mode.. not with any sim..

Ruim is basically used when it comes to cdma sim card.
"Removable User Identity Module (R-UIM) is a card developed for cdmaOne/CDMA2000 ("CDMA") handsets that extends the GSM SIM card to CDMA phones and networks. To work in CDMA networks, the R-UIM contains an early version of the CSIM application."
Your is at&t 4g gsm card. [emoji4]
Check your build.prop and search for
ro.build.target_operator: OPEN
Most probably for global mode open works
For making it work on cdma nv, i have set it to SPR
You can tweak with it by changing to options, it will also change signal bar and 4g symbol like at&t
These will show a Standered international 4G data icon for 3G/HSPA+ and LTE for LTE.
ro.build.target_county: CA
ro.build.target_operator: TLS
These will show a standered international 3G data Icon for 3G/HSPA+ and 4G for LTE (Messes up settings menu pretty bad)
ro.build.target_county: SK
ro.build.target_operator: SKT
If you want the AT&T 4G and 4G LTE Icons.
ro.build.target_county: US
ro.build.target_operator: ATT

My fav cdma tools are qpst, cdma workshop, dfs, revskill and bit advance is qxdm All are freely available. I cant say which one is best hahah. Trust me for me, all of them worked at some instance when i was stuck. Revskill is great with htc finding spc. Though i used dfs mostly.
