Disable Global mode and CDMA - Motorola Droid 3

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.

VZW -> T-Mobile ?

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

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).

Calling not possible

Hey together,
since 5 or 6 h I do have a problem:
My One stays everytime on 4G, no change to H,3G or Edge. Means, I can not call out! Unfortunately there is no option to force my One to use only 3G, H, or Edge.
What can I do?
Best regards

I don't have a ONE yet, but you should be able to turn off the mobile network in the settings. It is part of the Google design.
My current phone also has a setting under mobile network to change the network mode, which is the same is forcing it between 2g and 3g. There are play store apps that get you to that menu, although there appears to be no way to create a toggle for it from the desktop.
Hm, where can I find that point in my settings?

Just lurking in these forums in anticipation of my HTC One arriving, so can't guide you through the menu yet, but I'd try these things first.
1. A quick toggle in and out of airplane mode.
2. A way to force a type of radio is to open your dialer and dial *#*#4636#*#* then select 'Phone Information'.
Scroll to the bottom and find the "Set preferred network type" drop-down menu.
I'm not sure what it will be set on as I do not have 4G, but in that menu should be an option to select GSM only. This will force the phone, if only for a while, to drop the 4G connection.
Occasionally my HTC One X would get stuck on 2G and this usually solved it. Hope it helps you.
Okay, I will try it. Thank you.
But is that normal behavior? Does it often happen?
BTW, I'm on TrickDroid 4.0.0!

It is certainly not normal behaviour as your phone should be shutting down data to make voice calls. (Unless they have changed something recently or 4G works differently to 3G). In any case it should definitely not be preventing you from making calls!
You may be best served searching in the Trickdroid forum thread to see if anybody has had similar problems. Does that ROM have a custom recommended kernel? I haven't been in the development threads much yet.
Another thing to try if nothing works is to either flash the ROM back over the top after a cache and dalvik wipe, or extract the boot.img from the ROM if it is custom and re-flash that with fastboot. Don't forget to fastboot erase cache after flashing the kernel and before rebooting.
Then either quickly try another rom (take a backup first) or request a replacement SIM card from your network provider. I have had two faulty SIM cards, and one of them was a micro SIM with my One X which played hell with which radio it would use. It's rare but it does happen.

My wife has an S3 mini international version that we use here in CA on 3G/4G. If her phone is on 3G, then it won't make calls. She has to reboot it when that happens. For the moment she is living with it. I may have to put a custom ROM on there for her eventually. Evidently the 3G won't allow simultaneous voice and data, and her phone detects the data and refuses to call.
I realize it is a different device, but it sounds like a similar problem.
With the above mentioned key combination I can choose appropriate networks. When I use GSM only it works like expected. But I do not want to use that combination everytime to switch from LTE to GSM. Is there any other solution?
No solution for my problem?

CM 10.1 and GSM

Probably should be in the developers thread, but I don't have enough XDA 'cred' to post there yet.
No mater what I do, I can't get GSM working properly with CM10.1 nightlies. Tried many of them. All them seem to get a com.phone error on boot.
The phone doesn't register with the network and I can't call it. I CAN however make calls, but 'com.phone' crashes on exit.
All I can think of, when the 'phone' application tries to log onto the GSM network it gets a response back it doesn't understand and crashes.
I'm not in the US, so in theory I don't need any of the GSM phone hacks. (Australia). I don't have any other carriers SIMs to try, so I don't know if it's just a response back from my carrier that it doesn't like.
hi, i live in Brazil and we don't have any cm10 mod running in gsm version, in the max we have the version 2.3.6 running all the features correctly (here in Brasil we say Milestone 3 the Droid 3 and he works in GSM mode).
wanted some developer auxiliasse we modify this problem

Probably should be in the developers thread, but I don't have enough XDA 'cred' to post there yet.
No mater what I do, I can't get GSM working properly with CM10.1 nightlies. Tried many of them. All them seem to get a com.phone error on boot.

I had similar issues. Try to install cm10.1 again "without" the simcard installed, after that change GLOBAL in network mode to GSM. Power off your phone, insert your simcard and boot up the phone.
I hope that will solve your com.android.phone problem
P.S. after these steps you can select global again or the other network options to enable data (To make data work you need to insert the correct carrier apn settings)
Did you ever get this working?
Did you flash the gsm radio file ?

[Q] Troubleshooting Mobile Data

Good night my fellow modders. Tonight i come with a particular query, mainly, how do i go about troubleshooting the 3G connection of the motorola razr i. Ever since i flashed Omar's Motorola 4.1.2 Rom from Jan-01-2014, i haven't been able to get internet access through my carrier (Not even through 2g) and ive already checked its not a carrier issue (Since i can use my simcard to browse the internet in another phone just fine), i even tried doing a nandroid restore from the stock firmware i had previous to starting this adventurous task to get things working again, but even then the mobile broadband service is a no-no.
I'm at a loss on what to do, since i've already tried reflashing the ROM, reset-ted the phones APN's, and i've also done the suggested file modification of the losialert timer to both, 1000 and 500 (as seen in the same thread). However those efforts have been to no avail and im quite at a loss on what to do.
Im sorry if my english isnt fully understandable (Its not my native languaje) and im also sorry if this isnt the righ section to post about it, but i cant post directly in the thread since I'm a new member. I thank you beforehand for any and all guidance or help you can offer me.
Don't worry, English is not native language for most of forum users.
First of all buy any pre-paid card from different carrier or borrow it sim-card from friend and test it.
I had similar situation with Virgin Mobile. We have quite few operators in my country and I tested all of them but for this I wasn't prepared. I had my new RAZR i and there was no option to use internet with Virgin Mobile.
After few days of fight with different ROM, modding system, installing apps to APN's I figured it was sim-card. Some carriers have old sim-cards which have something wrong with MCC and MNC code and all phones can work on it but not Android 4.1 and above caused APN automation.
I even called to Virgin to ask for changing sim-card but they said they don't have different version of sim-cards, so I asked "WHAT, so every people in Your network doesn't have internet on Android 4.1+??!!" and they said "Yes, it seems so".
And there was no other way but change carrier. Now I have fully working internet without any modifications.
Sorry for so long and boring reply but for my almost 10 years working with mobile phones it was first situation like this.

Thank you for taking the time to answer my query. Unfortunately, i believe your case doesn't apply to me, since i had no issue using the internet with my operator (Telcel) before flashing the new ROM. I've also already called my operator and they made several procedures to try and reestablish my service, however none of them worked, but they assure me it's a problem with my device, since their service is working correctly.
I have no idea what to do now, but i hope can get the minimum required limit i need to ask for support directly on the thread ;(.
I don't know if this will help.
I had this problem with my brothers phone (galaxy s4 mini) last night. Data wouldn't turn on in anyway. Flash in new ROM from recovery didn't did the trick, nor a nandroid did. The only way I have got it to work was flashing a stock ROM through ODIN. In this case it would be RSD lite. Maybe it I'll work, but be aware of the flashing problems red lite can give. Read it a bit. Good luck!

Do you have the correct APN entries?? You might need to add it manually...
That happens because it doesn't auto configure (correctly, or none at all) for some carriers because I don't have all the carriers in apn-config.xml -- while your specific carrier ROM might have had it already configured and a specific xml list for them.
If you reset APN's and see all the appropriate ones added it might be configuring a wrong ones by default according to the data from the apn-config.xml one in my ROM, just configure accordingly to your carrier information
Note 1: My ROM does not touch the radio, and since the radio images are international anyway it does not make sense to flash recovery images or anything ... the only problem (assuming you did not break anything in hardware during ROM flashing) comes from the android /system partition which is prone to have incorrect carrier settings for data configurations... any bad number or password updated on your carrier it would be configuring something else by doing "reset to default"...
Note 2: To save the APN entry don't exit ... press the options menu and hit save when done modifying -- else it won't remain saved!
The problem starts when You updated from 4.0.4 to 4.1.2??

Did you try to change the APN settings before you tried this? I'm only asking because I'm considering this option, but i would like to rule it out as my final option, because since i started having this issue I've been reading a lot, and the way you fixed your problem sounds like the stock ROM corrected your issue by giving you the default APN's for your carrier.

I'm afraid i was already on 4.1.2 by the time i installed Omar's custom ROM.

Thanks a lot for getting out of your way to help me Omar; After troubleshooting the device and several talks with my network carrier I've managed to get a so-so signal. I'm not sure if your ROM configures correctly or not the APN'S of my carrier (Telcel) because when i edited them everything was configured as it was supposed to be (I'm not sure about the password since i can't see it though), the only thing that was missing was the APN for GPRS, but I've been reading several forums and almost no android device needs this in addition to the 3G APN (I've added it nonetheless but the device isn't actively using it, my guess is that you've got to choose either 3g or GPRS); I also called my carrier, and the allegedly reset-ed my service.
I'm still not sure if the device is working properly, mainly because the internet access through the mobile network has become very unstable (Sometimes i get disconnected randomly, and turning on the Wi-Fi gets me disconnected automatically), and even though the radio almost always gets an H+ signal (Which is kinda funny, because i used to get 3G more consistently before) i don't think this is normal behavior. I think it may have to be with the los alert, because in my desperate attempts to get things working, i reflashed your ROM and it was set to 1000 once again and I also think that the hardware can't be broken because i wouldn't be able to connect to the data service otherwise.
Because of this i would like to ask two very specific queries, is there a way to flash this setting without flashing the entirety of the zip file?; And in case there isn't, if i flash the zip with the new configuration, and then proceed to perform a nandroid backup of my previous build, will i lose the new 00radio configuration?
I will be tinkering with the device this weekend and will report back if i can find whats wrong, just in case it's something else and somebody needs help troubleshooting this in the future. Thanks to everyone that has contributed so far, i wouldn't have learned so much in so little time without your help.

Hmm, don't know for sure. I have made some changes within the APN list to get it working, didn't work. But the rare thing was that the cm11 one did have data and when he flashed his stock back with a nandroid or a stock zip file data wouldn't turn on anymore. So I can't rule out that it was the APN list that was making trouble, because even with stock it did not work. Only by flashing through Odin it worked. Radio hasn't been flashed in that process.

CDMA Workshop alternatives and can I get data on other carriers?

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..

so in my case i use att on ls991. my build prop is ruim,sim i believe. now does that sound rite for gsm?
also another cdma workshop alt if qpst i used that one to rebuild my g2 a few years back

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.
