Potential Solution for Unlocking Bands on Droid 4 in US

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?

Workig Bionic on T-MO Running official ICS OTA update guide

Success!!!
This is a step by step that I used and it worked(Tmobile) for official release ICS:
01. Update to ICS
02. Power off phone and wipe data in Stock Recovery
03. Power on phone and edit the hex values with Radiocomm see: post 29/30 http://forum.xda-developers.com/showthread.php?t=1297714&page=3
04. Power off phone
05. Remove sim card
06. Power phone back on
07. Connect to PC
08. Root
09. Delete STK.apk (edit: you no longer have to delete, just rename to stk.apk.bak)
10. Delete STK.odex (edit: you no longer have to delete, just rename to stk.odex.bak)
11. Modify Build.prop values as is:
ro.telephony.default_network=7
ro.mot.phonemode.vzw4gphone=0
telephony.lteOnCdmaDevice=0
and add this to the bottom:
ro.telephony.ril.v3=signalstrength
12. Power off phone
13. Insert SIM
14. Power on!
15. Dial *#*#info#*#* switch to WCDMA Preferred
Should be good to go!

I'm sorry, but I need to ask a question that is probably frustratingly obvious,
When I go to use the RadioComm tool, the instructions says to put the phone in PC mode. I can't find PC mode on the phone, and whenever I try to use RadioComm, everything is red... the blood-red of failure...
How did you get around this? I've only had the phone for an afternoon (I'm enabling TMobile for a friend) so maybe I just don't know where the button for PC mode is!
Thanks for this. I was about to give up. I thought it was required to downgrade to the last GB rom (which is, apparently, impossible). I'm glad to give this a shot.

Haha... It turned out to be just as stupid an error as I thought it would be... I didn't have the correct drivers installed -.- . I installed MotoCast, rebooted, tried again, and it worked! Yay.
Thank you!
Also, more notes for people who are as moto-clueless as me:
Stk.apk and Stk.odex are in /system/app
build.prop is in /system
It now accepts my Tmobile SIM, but it can't find any service. I've looked around, and it seems that lots of people with TMobile are having no luck with stock ICS, but ATT works fine. Any ideas? I changed ro.telephony.default_network=7 to =0 because that's how it appears in my TMobile MyTouch 4G Slide.

Try using my build.prop file. Heres the link to my post. http://forum.xda-developers.com/showthread.php?p=33261067

Do you have it working on T-Mobile? I gave it back to him this morning, but I sent him idiot-quality instructions to replace the build.prop. He says it doesn't work. He's on prepaid, so he as decided to just switch to Verizon. (This is a great idea where we live, T-Mobile has 2G and Verizon has 4G...) I hope this is an isolated instance rather than a generic problem with T-Mobile on the Bionic.
If I'm walking with him past an ATT store, I'll see if they'll let me try a SIM, so see if it was just me or if it's locked (or something?)... Unfortunately, there aren't many ATT stores for hours of where we live

Yes I have it working on T-Mobile here's a screenshot. The reason 3g/hspa+(4g) doesn't work for T-Mo everywhere with the Bionic is because they are in the process of switching bands to the standard 1900mhz band in the US. ATT users get full use of their band and 3g/hspa+(4g)

Yes they have the same type of network but they work on different bands. ATT=1900mhz T-Mo=1700mhz(switching to 1900mhz by end of year) The reason SMS/MMS isnt working is because you need to modify the build.prop file in your root folder. Ive attached the 1 click root program for the Bionic, use this to root your phone. After you root your phone you will need to download some type of root explorer so that you can access the root folder. You no longer have to delete the STK files just rename them with .bak extensions. They are located in /system/app. Then access /system and switch to R/W mode. You have to edit build.prop with the values in the guide.

T-Mobile AND AT&T

Works, but i'm only pulling 'Edge' Network. No 3g like before
Thank you VERY much. But i've got some information and a question...
I was too excited to try what you said to do so i didn't go back and read the instructions on post #1.
My phone had the SIM already still in it.
WCDMA was selected
Hex was still set to AT&T/Tmobile.
Then...
-- I Root it.
-- I edit files as given above.
NOTHING CHANGED! CANT SEND SMS STILL!!!
-- Powercycle.
NOTHING CHANGED! CANT SEND SMS STILL!!!
-- Reboot, wipe cache, wipe data/factory reset.
turn phone on: FULL BARS! (had to wait 1-2 minutes. and input SIM password)
Had Voice, but the calls kept failing
--Input APN for ST(att)
SMS/MMS work!!
Voice works
DATA works! ( Shows Edge2 )
My question is, Booted up on: GSM/CDMA Auto (PRL)
GSM = -80dBm
Network: home. ( i have never heard of this.)
IMEI: unknown
my phone number shows on *#*#info, and under phone information -unlikebefore it did not. Yet my IMEI isn't showing... It did before.
The network i had before i made these changes phone displayed ATT as network, not it is 'home'
network type before was HSPA/HSPA+/Edge, not it is just EDGE2.
So i'm not on ATT like before, i am on GSM?
When I send SMS/MMS to my other phone it takes 20 seconds to 5 minutes to show up on her phone.
When I am sent SMS/MMS it takes just as much time to show up on mine.
after about 20 minutes of running the phone SMS send normal speed.
I never did do the "then access /system and switch to R/W mode." Because I don't know what you mean.
when i switch to WCDMA preferred, it took about 3 minutes to load up a signal, The network type is still 'home' before all this it used to be 'ATT'

T-Mobile is in the process of a complete "re-farm" mainly to make their network iphone compatiple. This means that everything on the network should be operating on the 1900mhz band by spring/summer 2013 which is when they are rumored to be getting the iphone. Regardless, if they still don't offer the iphone this refarm allows any unlocked iphone to be used on their network and get full HSPA+. You can bring an unlocked iphone into their store now and they'll put it on their network but if you don't live in an area where the re-farm is complete you'll only get EDGE access.
This update also applies to any other phone that operates on the 1900mhz band, not just the iCrap. T-Mo also just bought MetroPCS which, in itself, is not a huge deal as far as coverage goes BUT they also get all of Metro's spectrum (plus the spectrum they got from ATT and the failed merger) so they are actually lining themselves up to be the carrier with the most available spectrum as the FCC only has so much to auction off. I am seriously considering jumping ship for them even with my grandfathered unlimited data. They've got unlimited everything for cheaper but I have to see how service is.
I honestly was not aware the Bionic was HSPA+... probably just from not researching it as I have VZW anyway right now... My contract is up in March and even though I am grandfathered unlimited I might give them a shot. They actually charge less for "bring your own phone" and their deals are pretty good. Wife wants iphone and with the re-farm she could have one on T-Mo but her contract is not up till March 2014 so the ETF plus unlocked iphone... $1k... um no... Maybe when she sees how awesome ICS is vs GB she'll change her mind...

can I ask what you mean when you say you input sim password? Im trying to get it to work on t-mobile... Well I have 2 bionics, one is mine and I got t-mobile working fine using the radiocomm edit, removing the apk/ and odex file listed by DBoyFresh954 and doing the build prop edit listed by him in the same first post. but the 2nd bionic is my friends and I cant get t-mobile working on it. The only thing thats not the same on the two bionics is my friends is HW B 43/11 while mine is HW A 34/11. If anyone might have a fix or can explane the sim unlock that scarocean was talking about please do post or pm me would be most thankful

HELP!!
Okay, so I got my T-Mobile SIM card in today. Followed everything perfectly and still nothing. No service or anything. I double checked my area for coverage and confirmed that T-Mobile does have service here. I'm on stock 246. I rooted, applied the gsm unlock zip, re-named the stk files, edited the build.prop settings, and switched to WCDMA Preferred. I have the HW B version if that matters. I've been looking everywhere and can't seem to find an answer. Could somebody help please?!
Edit: My phone is now showing AT&T as the network. Also noticed that my Signal is reading -81 dBm and 16 asu. Isn't that a good signal?

I followed post #1 exactly and my Bionic works on T-Mobile.
What do you mean where you said "applied the gsm unlock zip" --- Either I missed this part or do not understand what you are referring to.
Running rooted Bionic on Synergy ROM on T-Mobile.
I do have a question though....
How to prevent phone from going back to LTE when rebooting. Not the worst thing but have to modify the radio each time phone is rebooted???
Also the ones who got it to work as well, are you getting 3G??? I feel as though I am not....
Thanks again to the person who started Post #1 --- Saved me $$ from buying a new phone from T-Mobile.

What do you mean where you said "applied the gsm unlock zip" --- Either I missed this part or do not understand what you are referring to.

I flashed a zip that does what you did in Radiocomm. I finally got fed up with the problems and went to AT&T and got a SIM with prepaid. Works great! I just could never get the T-Mobile SIM card to work. Didn't go to waste though. Unlocked my wife's Torch and used it for that.
I have no idea how to make the settings stick for reboots. Odd, that your settings don't stay on WCDMA Preferred. Mine stays after reboot.
I think the Bionic can only get 2G until T-Mobile has finished their refarm. I think there's only a couple that have been set. Don't quote me on that though. Haven't really looked into it a whole lot.

just a bit more about files and build prop
I have the droid bionic and I was attempting to get my at&t service on the bionic. I have made it as far as the root step. Where do I find the files to delete? I have a folder /system on my PC but I can't find /system on the bionic. Where is the /system/app folder? Do I need to use device manger find it? A few more details would be much appreciated. a list of files and programs needed would be a nice addition to walkthrough. Just a thought. Plz help thanks

Download ES File Explorer. Hit the menu button once you open it and go to settings. Scroll down to root settings and select all options. Go back to the main menu and hit the Up button at the very top. Scroll down and click on "System." Once in you'll see the "App" folder immediately. Click on that and scroll down to the STK apk's. Once your done renaming go back once and scroll down till you find the build.prop. Click it and use the ES note editor to edit the settings.
As far as adding the signal strength to the build.prop goes just scroll all the way down and add it there.

When you do this edit, can you switch back to Verizon's CDMA/LTE by switching sim cards or do you need to redo both the apks and Hex edit?

Samsung ATIV SE - No internt sharing

Hi All,
I got the ATIV SE and really like it. Problem is that even though it's unlocked SIM and I have also developer unlocked it, I cannot get internet sharing to turn on. I bought from Verizon, but am using it on T-Mobile. Error is:
To enable tethering on this device, go to Verizon.com or dial *611
What is the best way to get this phone to forget about Verizon? Is there a way to just factory reset to vanilla windows?
Thanks for help

I'm not sure but could it be possible that your carrier lock Tethering?
Have you tried an oter csc?
Or can you flash an other ROM`?

Thanks for the reply. No, carrier does not lock. The problem is with the phone being set up to think it's a Verizon phone. Is there a way to flash another rom here? or something like root?

We can interop-unlock Samsung WP8 phones, although if it's fully up-to-date it may need to be downgraded first. I don't know if that will help you, though. I can't tether (well, not over WiFi; wired works) my non-T-Mobile phone on TMo either.

There won't be another CSC to flash... Unless you can get @-W_O_L_F- to help you out with a custom rom....

Sorry for the slow reply. I didn't get notified by this site that there was a reply to my post.
Can you please help me out with how to do this with ATIV SE?

Interop-unlock instructions are in my signature. I don't know if they'll help you though, and if you're on GDR3 (probable) then you'll need to downgrade first (or use a custom ROM) and for that you need to read @-W_O_L_F-'s threads. I don't know if there's a base ROM (non-Verizon) for the SE; if there is you can probably flash that but we may not have one.
If you wanted to know how to do wired tethering, just search for "tether ATIV S". Seriously, #1 rule of this forum is literally "search before posting"

Seriously, thank you for the reply. I did lots of searching, but since ATIV S and SE are quite different, I wasn't sure if anything related to S would work.
I'd love to flash an SE base ROM on this, but I haven't been able to find that there is one.
The MS Store in Bellevue said that they would be getting a Samsung base ROM in a couple months that they would flash onto my device for me. But I'd like to do this sooner.
Should I reach out and read wolf's threads to see about using a custom ROM here then?
Thanks!

Try a variation on the following method:

Worked for the HTC 8x, should work for Samsung as long as you can put in the right model ID. (hint: it's not "dm=Windows%20Phone%208X%20by%20HTC" for your Samsung.) Good luck!

Thanks for that! The process worked and got me almost there.
Ok! Super progress here. This is what you need to add for the Samsung ATIV SE
// Replace oemId=Samsung with oemId=NOKIA
oSession.PathAndQuery = oSession.PathAndQuery.Replace ("oemId=SAMSUNG", "oemId=NOKIA");
// Replace the device model with the dm for the Nokia 925 (AT&T / North America):
oSession.PathAndQuery = oSession.PathAndQuery.Replace ("dm=ATIV%20SE", "dm=RM-893_nam_att_206");
Note the CAPS for the oemId.
I installed Access Point (along with some other cool Nokia Apps). I went to enable Internet Sharing, but now I have a new message:
Add Internet sharing?
"Your current data plan doesn't include Internet Sharing (it does). Do you want to open an app from your mobile operator to add it? Internet sharing use your cellular data and may incur additional charges."
Any ideas where to go from here? Clicking Yes does nothing. So does clicking no.

At this point, I'd call T-Mobile and see if they can double-check everything on their end. They might need to reprovision your data services. I had a similar issue with my old iPhone when I added the 500MB tethering option.
They do have an "access point" app (I forget what it is called) that comes pre-installed on their phones. (Literally useless, it is so when you click Yes on the "learn more" button" it tells you to call customer care to enable internet sharing. I always delete it off of mine when I restore from stock).
That is another fun trick: to get rid of apps you can't uninstall, set the date and time on your phone to later than 2200 and click on the app...it will tell you that it expired and give you the option to uninstall it!
Let me know how you make out!

fruehling,
Did you ever get this solved? I'm planning on getting this phone too, but for use on At&t. I hope I don't run into the same problem. But I do have some questions to ask you, I hope you don't mind answering....1) Does the voice call works as any unlocked phone? .... 2) Can T-Mobile detect that you're using an ATIV SE? Or does T-Mobile says you have an Unknown device when you check your online account? Thanks!

If you are in Dev Preview.. try the foreign sim trick
if not just install a new keyboard.

I followed the procedure outlined, and using SysAppPusher, it attemped to install "access point" under Microsoft mobile (not Lumia), and from the store, the status changed to "owned". But it didn't actually install it.
I turned off the proxy (as it was recommended) and it still didn't install it. Any idea as to what could be wrong?
I'm on the latest 8.1 release.

Unlocking Sprint G Flex to Cricket/AIO/ATT Wireless

This tutorial is my method for successfully unlocking the G flex to Cricket/AIO/ATT wireless with data/MMS, No battery drain, no Wifi calling drain.
1. Pros. Use Cricket/AIO/ATT sim.
2. Cons. Must dial International code +1 ( or whatever country code you're in) before every 10 digit number.
********Before we start you need to be on stock 4.4.2 sprint rom with Network Mode LTE/CDMA enabled************
(The roaming option does not appear when on GSM)
Next, change theme from "FLEX" to "LG". For some reason FLEX bugs out after the phone unlocks and causes crashes. (May be an isolated incident)
*Now we need to add the APN from AIO wireless into the Apn list by going into settings>roaming>Access point names
*The APN list will be blank and state "NO APNS" this is normal. Hit the menu button and add the AIO wireless APN settings from
http://buzzmobile.us/aio-wireless-apn-settings-internet-mms/
When completed you will need to press the back button and once again you will be greeted with a blank APN screen. Don't worry it's there.
Follow the instructions for root + unlocking the phone here. Total commander doesn't work on 4.4.2, don't use it, do it all with Root Browser (Get from Play Store).
http://forum.xda-developers.com/showthread.php?p=50477852
After you are finished you should be rooted, successfully finished removing bloatware and left with a half unlocked phone.
Now navigate to settings/tethering and networks/mobile networks/Network Mode and change to GSM/WCDMA
**********************You are finished with this portion of the Tutorial***********************
*Fun Part*
1. Download Rom toolbox on your phone, the free/lite version is fine.
2. Navigate to build.prop editor
3. Find and change the settings listed..
ro.carrier=spr (spr to lowercase)
ro.build.target_operator=spr (spr to lowercase)
persist.service.crash.enable=1
Lets keep something in mind here... Once you change these settings you will need to restart your phone and you will be unlocked for Cricket/AIO/ATT networks, however, at this time you should know that if you venture back into network mode and happen to change your settings back to LTE/CDMA, you will lose the ability to change your network mode back to GSM UNLESS you revert the build.prop changes listed above. You can actively switch from LTE/CDMA and GSM by this method although I don't see why anyone would..
At this point you should have Talk/Text/Data/MMS...If not, you may have done something wrong.
**More funner part***
At this point in the tutorial your phone is doing two things.
1. It lies when it says its only on GSM/WCDMA
2. Rapidly draining the S#$% out of your battery.
We need the MSL Code so we may dial ##DATA# in your phone and access LTE settings.
Follow this Tutorial for retrieving your MSL code.
http://forum.xda-developers.com/showpost.php?p=47324060
After you obtain the MSL pull up the phone application and dial ##DATA#(3282) Navigate into LTE and disable LTE/Band 26/Band 41
When you back out of the menu your phone will restart and stop continuously looking for LTE Radio.
**Final touches**
Remove all and I mean ALL sprint and preloaded wifi calling applications if you experience wifi calling battery draining. For some reason wifi calling spazzes out.
I'm not going to list the apk's because it may be an isolated incident and if you find out wifi calling is draining your battery just long press it in battery stats and go to "APP INFO" and find out what it is named and remove it with root browser...
I have been on Cricket/AIO wireless for two weeks now with HSPA+ and enjoying it.
This method may work with other carriers who knows.
**Food for thought**
1. When I change the ro.carrier settings from lowercase spr to ndo like in the APN i got a cool h+ instead of GSM.
2. I have not been able to wifi tether yet with cricket and I'm actively looking for a way now..
3. Think anyone else has issues with the FLEX theme crashing?

thanks.

If you don't mind how much do you pay? Will this work with a T-Mobile Flex? I'm pretty happy with T-Mobile since I got my discount back. I have 4 lines so it's around 25 bucks in savings a month.

It should work with t-mobile, i don't see why not, instead of ATT/AIO apn's just add a Tmobile apn and make sure that you have some time to play with the build.prop settings for example...
ro.carrier = spr can be changed to ndo and still work because "in theory" it matches the APN.
After adding the tmobile apn setting, changing ro.carrier to " t-mobile" to match the apn might work .
Try it out and see!
p.s i would leave ro.build.target_operator=spr alone, if all else fails you can change this too.

Thanks for the guide . I picked up a sprint g flex and lg g2 cheap, used your guide on both. Enjoying them on NET10 in the states.
patiently waiting for a custom recovery for kitkat on the flex.

interesting thread. i keep running into an issue though. as soon as i reboot after changing the stuff it reverts to where i was before and nothing saved. any suggestions? root is fine...
awesome stuff here i really want to see this happen on my flex!

Wont allow apn change
so i got stuck with a simple issue. when i go into the apn list there is an apn there already.
cinet.spcs
and when i press the menu key it is not showing the add feature to be able to add the new apn as described in the thread.

after doing these I noticed when opening Wifi it force closes and says "Unfortunantley, Settings has stopped"
only wifi that works is the one i used before doing these mods wont allow adding others
also have tried various wifi repair apps

working for me but getting tons of systemui crashes

Concerning the errors that appear often but I came out I did this : I returned and change in the build prop, spr for SPR capitalized and not returned to me the problem also remove the option to persist crash : 0 , take into GSM mode UMTS network selection mobile. I'm in version 4.4

Not working for me.
I tried this 3 times. Once with stock 4.4.2. Once downgraded to 4.2.2 and another time after updating back to 4.4.2 from OTA. All failed. Could not get any sim to be recognized. I am a smart guy and have done much more complicated methods of flashing, rooting, etc. for Android phones. But this just does not work. The phone states no SIM when I put my Cricket SIM in it. But when I put the Sprint SIM back, it reads it.
Any help would be GREATLY accepted. Thank you.
PS: I called Sprint because this is a clean phone. When I asked for the unlock code they gave me the MSL. I have a feeling that is incorrect but I could be wrong. After an hour on the phone, they said that is the unlock code. No matter how much I tried to tell them it's not.

Maybe this is a better guide for you:
http://www.droidviews.com/how-to-sim-unlock-sprint-lg-g2-ls980/
The Sim unlock does work, I've been using my sprint g flex on cricket for 6 months or so , but only with H+ .
You don't really need the msl or have the phone in good standing (blacklisted is OK).
If the Sim isn't being recognized that means you didn't do the folder replacement right. I had trouble at this part, which was solved by using the app "ROM toolbox". It took a few tries.
As far as changing the APN , just use any shortcut app on the playstore.
For switching bands, use the app " network" from the playstore. No msl needed.

Did you use the files from my link? Flex specific?
Don't use total commander.
What software version are you on?
Even after the FC, does it recognize your Sim?
You must also change the build prop, just realize the guide doesn't have that. Probably why your getting FCs.
Save a copy before making changes:
ro.carrier=spr
ro.build.target_operator=spr
persist.service.crash.enable=1

Sweet. Glad you got it.
The only trouble I have had with this method is if the phone shuts off or I restart, I have to switch the bands back to GSM.

Mobile data not working on some apps

I have Motorola Droid Turbo XT1254 Verizon model and I am using it in Asia on a non-Verizon network. Everything including wifi is fine, all apps working but I face alot of problem while using mobile data.
It only works on WhatsApp anf Google maps, I cannot even browse the internet because it doesn't work on Chrome. I tried other browsers but I can only browse the internet using Opera Mini but that has also stopped now. I cannot even call a cab when I am outside because because "Careem", the cab app says that I am not connected to the internet.
The H+ sign appears when I turn mobile data ON and I have also checked with my network operator, there is no issue at their end. They say there is something wrong with my phone.
I don't know where to start the troubleshooting. Can anyone help pl? Thanks in advance.

Someone advised me to check my APN settings. I went to the APN settings and there was nothing there. I first reset it to defaults and then added a new APN according to my network settings and everything is working fine now.
Whenever you put a new SIM, APN settings are automatically sent by the network and saved by the phone but that didn't happen to me so I had to do it manually.
Hope this helps someone someday!

Are you on a custom ROM or stock Verizon Marshmallow firmware? There's another issue with custom ROMs even for people on Verizon, the default is Straight Talk (an MVNO), not the REAL Verizon. (Because S comes before V, alphabetically.) It's an MNVO using Verizon signal, but REAL Verizon customers will often not get messages, get very slow speeds --- and they don't know anything is wrong because nobody ever checks their APNs anymore.

Is your bootloader unlocked? Do u have TWRP?
If yes then just flash clear-modem-status.zip by @bhb27. Search it using xda search.
If No then reflash your stock modem via fastboot. There are tutorials for our device on how to do so.

Thanks for your reply Zadeora but my issue has been resolved now. The APN settings were incorrect. Now all good
