Sprint G2 GSM UNLOCK (US Carriers) Easiest Method!!

*YOU MUST BE ROOTED AND USING AN AOSP ROM*
CM11/PA/PAC-MAN/LIQUID SMOOTH will do the trick.
*Pop in a US Sim card (Tmobile, AT&T, H20, Family Mobile etc.)
*Open dialer app
*Dial *#*#4636#*#*
*Choose Phone Information
*Scroll down until you see the Network Type
*Click the box and choose GSM ONLY.!
And that's it folks. You will see the service bars appear after about 2-3 seconds. Set your apns if not already set and enjoy GSM carriers on your Sprint G2.!

The easiest way.....just install any cloudyfa ROM with your SIM. You will get GSM network out of the box.

Hi I'm new to g2 world. I have a ls980 and I live in Europe so I flashed g3 port that has working gsm sim cards. My problem is coming from n4 I can't live without aosp. My favorite rom is carbon, which I tried but couldn't connect to gsm. Anyone have any idea what to try? Thanks in advance.

It really works!
I didn't think it'd work at first, because of all the other unlocking methods out there, like changing carrier files, unlock codes, T-Mobile ROMs, but I can happily say it works I tried it with an old Metro pcs sim I had. I got the "No service" signal because it isn't activated, but at least its detecting the sim card Thanks for the info! Oh, & I was using the CloudyG3 ROM version 1.2 & it still worked

No LTE, since the needed bands are missing from the phone. But yes, 4G (HSPA+). Several weeks now on Cloudyfa G3 ROM v1.2. Pick "WCDMA preferred" in the mobile network settings, and choose the T-Mobile APN without LTE, although the LTE one seems to work OK as well. If you have any issues kick-starting the GSM radio you can download Radio Switcher from the Play Store.
The only issue is that some of the T-Mobile towers haven't yet been "refarmed" or "unlocked", so on this device in that case you would only get 2G data. For example at home I get HSPA+, but at work only Edge/2G. Hopefully that will change in the coming weeks to months as T-Mobile continues to upgrade its towers. The same issue applies to a Sprint iPhone 4S and Republic Wireless Moto X that I unlocked and am running on T-Mobile as well.

Guys I'm new to this rom update business, I mean I have done plenty of windows phones but none of the newer androids.
I have an LG G2 32GB Sprint (bad esn), purchased from ebay, but I'm in the UK.
Any idea of how to get it working with the UK?
Links and instructions would be most helpful
Thanks in advance

Sorry cannot provide links I m on the go. First you need to check if you are on latest ota which is zvd. If you're on zvc root with latest iroot. If on zvd search the forum there is an apk which you just install to your phone and run it (called towelroot). It roots even without reboot. Then search the forum for ls980 permanent unlock and follow the guide. Just use any root explorer to copy the files, restart and you are unlocked but with no speed data icons on status bar. The other way, is after rooting, install autorec (search for it - it's tricky, you might brick). Autorec is needed to install custom recovery. Then just pick a rom from cloudifa (g3 port is great with no bugs). His roms are made for gsm and you will be already unlocked. If you prefer aosp based, only one that worked for me after changing some settings and restarting is Omni. Couldn't make carbon (discontinued), vanir and mahdi to work. They didn't even recognize that a sim was inserted. Before flashing a custom rom, make a full backup via custom recovery and make sure you get familiar with how you enter recovery and download mode with hardware key combination. Keep in mind there is always a chance to brick and then you will have to enter download mode and flash back to stock with lg tool. If you are confused ask any questions and I ll try to help when I get home on my pc. Did all above a week ago and ended with cloudifa g3 port and is working great so far (I'm in Greece).

Thanks very much for your help and advice, I can get as far as unlocking the device and it all works However, how do you enable data? If I can enable the data then I'll keep the normal ROM and use it
Also after installing a custom recovery, the autorec works great and I can understand the concept of it, but then when I flash with the cloudifa g3_1.2 it flashes but when the phone restarts it gets stuck (first time at 49%, then had to reflash using stock via LGFlashTool, then second time at the LG logo) so I have to go back to the stock rom, root it, unlock it and back to square one. Unsure what to do next?

In order to enable data you have to check your apn settings. If there are no settings, try to set it manually (Google your carrier's apn settings). When you are done and you get data to work try a reboot to see if they stick. I think in the permanent unlock thread you can edit this file with the apn settings and add your carrier's ones. Also delete those 2 files so you can automatically have data after each reboot.
Now I didn't really understand what went wrong while trying to flash g3 port. Have you flashed the appropriate baseband? It's very important in order to boot. It's mentioned and there is a link as well in the op of g3 thread.

Bought this phone on eBay few days ago and I started checking around about how to unlock it(though it'd be simple as any other phones, but I guess I was wrong). Found few threads talking about how to unlock it for US GSM carriers but barely find any information about using it in Canada.
Looking to root\use a custom rom and read that the CloudG3 rom will actually GSM unlock the phone,but will it work as well for Canada(will be used on Telus network)
Thanks.

As long as the band's are supported it should work.

There's a Rom on xda that converts the spring variant to the T-Mobile variant by flashing the Rom. It's basically a T-Mobile variant g2 cm11 Rom but with a Sprint boot.img and a few other Sprint files to make it boot. But if I'm not mistaken it has the T-Mobile radios in it. That should get you their full network experience.

Think this thread might be dead but if I get a reply it'd be great. Will the OP method work on the latest CM12 nightly? Or does AOSP here refer to only the CM11 variant?

Currently not the Device Maintainer for the G2. I'm working with the G Flex community now. I'm pretty sure there's a CM12 nightly already released. Updates will be posted in whatever thread you originally downloaded it from

Phone locked after flashing Stock Sprint G920PVPU3BOL1 (Android 5.1.1)

Hello dear all,
I bought a few days ago a Samsung Galaxy s6 phone in my country. As I am a bit curious, I noticed later on that the phone have been unlocked before I purchased it with the local seller, as it worked fined with my local SIM Card operator.
I also noted the phone was CDMA, as there was not anywhere I could setup an APN. I used a third party all, APN Configurator (downloaded from the Play Store) to define a custom APN and then I could go the the internet using mobile data. I used the phone for two days without any noticeable issue. Then, one night, I rebooted the phone and it got stuck into a bootloop, with a message displayed in red in the upper left corner of the screen : "Custom binary blocked by FRP lock".
I made some research and I understood FRP lock was a sort of protection related to OEM (which could be deactivated in Developer Options). I did not knew anythting about that. Anyway, as it was useless to me at this point since I could not even start the phone.
However, Download mode and Stock recovery were still available. I downloaded and flashed a stock rom for Sprint (G920PVPU3BOL1) and I flashed it via Odin. It went fine. Now when I boot the phone, It gives me the following message :
"Attention - Power off your device, insert the service provider UICC that came with the device, then power on the device."
I get get past this screen. I only have Wifi-available, but still, I can't go anywhere with that.
I am loocking for a proper way/tutorial to bypass this screen and then unlock the phone from here.
Much thanks in advance.

Sent from my LG-H815 using XDA-Developers mobile app

Thanks @jinderation. I already came accross that tutorial. Unfortunately I can't apply it since it requires to install some APKs. I cannot even do that since I am stucked at the activation screen and I can't get past the message I mentionned before:
"Attention - Power off your device, insert the service provider UICC that came with the device, then power on the device."
So, no way to access to the menu, where I can connect the device to a PC and then send an APK and then install it from the device.
So I am looking for a proper way to bypass the activation screen first. Then I can proceed with the tutorial you mentionned.

Take it to sprint.. Have u checked for its imei no. Whether its blacklisted or not...the seller whom u bought from did he make his payments to sprint cuz if he didnt then you are screwed..share the imei number here so i can check
U can also try flashing this firmware its 5.11 BOL1 as well i dont know where u had downloaded the firmware from mine is also unlocked but doesnt show the type of screen that you are mentioning

A massive thanks to you! I actually downloaded an unlocked version of 5.1.1 BOL1 updated from somewhere else, not yours, I flashed it via Odin, and it workied fine. I even rooted it by flashing UniKernel for Sm-920P and its all perfect now.
Except that the Sprint logo shown at startup is a bit annoying, and also the battery life which is quite short....

Bought an S6 recently and it was on 5.1.1. It was already rooted and not showing firmware update option. So we thought we will flash the stock ROM and flashed the SM-G920P 6.0.1 ROM. After this, the phone displays the following message and SIM card is not showing any signal "Power off your device and insert the service provider UICC that came with the device, then power on the device". Any suggestions to fix this issue?

No working ROM for my P8000

Hi,
2 weeks ago I got my P8000 from the german elephone distribution, it came with android 6. It seems to be an other version of the phone, the fingerprint sensor has moved up near the camera.
So my problem is, that I can't find a working rom for this device. I tried to root the phone and after that it did not boot anymore, so I tried to flash the 6.0 stock rom but the screen is white with moving stripes.
Where can I get a working rom for my phone?

I think you should ask elephone (on facebook or some other social medias) for a dump, I don't see any chances that there are many people out there that own the 2016 version... :/

I wrote to the elephone facebook contact but they just pointed me to the BBS with the not working 'old' Rom file.
So if I could get another new P8000 would it be easy to take a dump oft it and flash it to my phone?

I think you won't have to buy a new device, just point out to them that, that rom on the forum is for the old version and it's not working for your's. I hope they'll provide it for you.

P8000B is almost impossible to brick. If you install SP flash, and download the correct recovery (like TWRP), and the correct version ROM's with scatter.txt you can recovery the phone in just about any circumstance. I put the P8000B recovery files on my PC, Formatted whole flash and bootloader. After that, the phone was bricked, and wouldn't turn on. Loaded the P8000B system recovery scatter.txt, and SP flash installed it perfectly. Booted fine. With SP flash it's almost impossible not to be able to restore the P8000B as long as you have proper files,

there is no Stock ROM, no scatter file and I think not even a TWRP or Philz Recovery available for the 'new version' of the P8000 - I call it P8000(B) because it is written on the box of the phone.
Emileh made a good description of the problem here: http://forum.xda-developers.com/elephone-p8000/general/2016-version-fingerprint-scanner-t3436270
But you could help us if you can provide the necessary files....

Is it the us version? It's the same one I have. I'll post a video how to soon
******EDIT******
FrauHofrat, sorry I did not realize that there was a "Rev.2" out for the P8000 US Version. I am surprised Elephone hasn't released a flash-able version for SPflash yet. Honestly, it would be in their best interest to ship any Rev of their US versions w/ TWRP and freely distributing flash-able images/scatter.txt, so if it gets bricked during a failed OTA update, folks would not have to send their phones back to be fixed. I have the Rev 1 of that phone.
Any word on the Elephone forum regarding the Rev. 2 version for images/scatter.txt? I will keep an eye out. Is there any specific model related info that shows up in About Phone, or written on the box/battery?

We're not talking about the P8000-B here, which I believe has different LTE bands so it's better suited for the USA
We're talking about P8000 6.0, which is the newer version of the phone that's currently being shipped in Europe. It has some small technical changes and stock Android 6
Edit: by the way, the box does say P8000(B), but I don't really trust that description

Hi guys,
I was just looking at the elephone forum and found this: http://bbs.elephone.hk/thread-11929-1-1.html#.V7WrLDWbfSY . There's the stock rom link for the 2nd revision of the P8000, so hope you can get it working properly again.

@ardrift
Thank you for this information - the ROM works and the phone is alive again!
But there is still one thing to do: because of flashing the wrong firmware my phone lost the IMEI. This should'nt be a problem on rooted devices but the stock ROM resists all attempts to be rooted

Can you try dialing *#*6813#*#* in the stock dialer app? Someone on the elephone forum has written this as a solution, altough I don't know if it works, or how would it work... If you are stuck you can upload a screenshot, I can look at it
PS: Your IMEI numbers should be sticked on your battery, you can see them if you remove the phone's back.

Change IMEI on P8000
@ardrift:
first I thought this is a joke but actually it worked :victory:
with *#*#6813#*#* entered on the stock dialer you can acess the "IMEI-Tool" which allows you to enter a new IMEI for both SIM cards. The new IMEI stay permanent even after reboot and this also works on 'old' P8000.
Sometimes life can be so easy

Convert/Upgrade the AT&T G6 to H873 OR US997 With VoLTE

Lets get those warnings out of the way! Warning Do this at your OWN RISK! There is NO WAY BACK to AT&T firmware at the moment and might never be. Only loss is you'll loose VoLTE and WiFi calling (If using the H873 Firmware)
Idea came from this thread which also perfectly works on the AT&T model! https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966 Its the same method.

Flashing firmware won’t unlock the device (any device for that matter) You need to unlock the device by unlock code.

Curiously the thread you've mentioned in the OP (https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966), claims to be able unlock the SPRINT variety only by merely flashing it with an "open network" type firmware.
In my experience, I've never seen any phone, ever get unlocked by merely flashing a firmware (even if it's "open network" type).
Usually the network lock information is stored in a non-volatile security zone, so this just doesn't make much sense.
Now, I'm not doubting the OP, it's just extremely unusual, but it could be an anomaly or firmware bug.

Well this thread is not for unlocking the GSM model which it CANNOT. It’s meant for having a generic open firmware removing all the AT&T junk. Meaning if it’s not unlocked it won’t be unlocked after flashing.
Now the Sprint model is CDMA which is completely different than how GSM works. Sprint CDMA phones are usually software locked to keep it from being used on GSM networks. That explains that

Getting moisture in charging port and another popup that asks if I want to keep it as a charging device for another phone. I'm sure it's a minor bug and a restart fixes it but I'll be trying to update tomorrow. Saw on a Korean site that there's newer options.
No regrets by the way. So nice finally having a modern os

Works perfectly, thank you very much!
But one thing: I had to start LGUP.exe with admin rights. If not it was not possible to choose the kdz file.
Btw...is there a way to remove Facebook, Instagram and the hole sh*t? For sure i choose remove LG apps as well but these apps still there.

Not without root

Got ya! Well now it makes sense... first, the description "unlocked" is a bit misleading, a more accurate description would be "un-branded" firmware. Second, on the Sprint side I can see how the open-firmware could "unlock" the network, course that would disable the CDMA side, only GSM would work.

Yes, here's how to disable any app WITHOUT root.
First, save the app list into a file with this command issued from your ADB folder:
adb shell pm list packages -f >c:\Apps.txt
Look through the saved file (c:\Apps.txt) with any file viewer/editor (like Notepad etc.), search and find the app's name you wish to disable.
For example, the Facebook app:
package:/system/app/Facebook/Facebook.apk=com.facebook.katana
Copy and paste "com.facebook.katana" (without quotes) into this command line:
adb shell pm uninstall -k --user 0 com.facebook.katana
The above will disable the Facebook app till you factory reset or update your phone's firmware.
Just repeat the command for all other apps you wish to disable.
Enjoy!

The H873 kdz works which was the point of this post.
There is no H871 flashable firmware out yet and quite possibly won’t be.

It wouldn’t have anything to do with the firmware unless 1. The LCD is for a different model or 2. Your phone is not a H871

US998 to LS998 *Sprint LTE + Root*

If you mess up your device I'm not responsible, it works for me, and for others. I will help as much as i can, but it is on YOU, the user to follow the prerequisites and read carefully. This zip was created in collaboration with @TxanMoe and myself
This zip can be used to return to the stock rom(for the most part, you'll still have fastboot,root,twrp) as long as you can get into TWRP recovery on the device. It also flashes the modem bands needed for working Sprint LTE(bands 25,26,41, ect.."all the Sprint bands")
Prerequisites:
1. Activate with Sprint first if you intend to use the converted US998 on Sprint!
2. You already crossflashed to US998 if not follow the guide here "Frankenstein method" [https://forum.xda-developers.com/lg...sflashing-t3780969/post76510671#post76510671]
3. You followed the bootloader unlock, root, TWRP "WTF" thread here https://forum.xda-developers.com/lg-v30/how-to/wtf-lg-v30-t3790500
(US998 to LS998) Downloads: (Sprint LS998 system,boot,modem)* MAKE SURE TO FLASH MAGISK, NO-VERITY OPT ENCRYPT, AND RCD DISABLER BEFORE LEAVING RECOVERY!!*
Sprint 20b
https://drive.google.com/file/d/1aQojUcchnEruHwnecfaVGToxZbmj-UX3/view?usp=drivesdk
Sprint 21a(may security patch)
https://drive.google.com/file/d/1JCalyu7mt8DW6wMWbgGViqj0oi9eUSr7/view?usp=drivesdk
*Instructions*:
a. Make a backup in TWRP of system,boot,and data before proceeding!
b. Reboot to TWRP and wipe data (factory data reset)
c. Install the SPRINTLS998.zip (20b or 21a)from TWRP (Do NOT leave recovery yet)
d. Flash Magisk, no verity encrypt, and RCD disabler(you should already have these files if you followed the WTF thread)
e. Reboot
d. Once booted up you need to connect to WiFi. go to settings, update profile and prl. Reboot

For anyone who flashes back to Sprint but needs to edit the APNs still, you can type this in command prompt(from PC)
Code:
adb shell
su
am start -n com.lge.hiddenmenu/com.lge.hiddenmenu.ModemProtocol.ModemProtocolMain
Then go to PDP Setting
Then go to APN setting

@JWnSC thanks to the help of some of you great people in this thread I have had the chance to do this conversion twice now. Both times it worked great but I did have to update the APN settings before getting mobile data to work for me. I know you were kind enough to include screenshots of the right APN settings but I just wanted to share that both times I used the ##SCRTN## dialer code to force OTA provisioning and it worked, so I thought you may want to add that option to your first post. Might be a good option for someone that's in hurry to get connected.
Only negative I can think of is that you would not have tethering unless you were subscribed or you manually added the "Dun" provision to the APN later.
Just wanted to share in case you thought it was worth adding to your original post. If not, no biggie. Thanks

Here is a zip for warranty exchange ect...*NOT Recommended* (you will lose root, TWRP)
https://drive.google.com/file/d/19FHVNn6TS5ybdNIziL1nyKPWcIc_RN0t/view?usp=drivesdk
From TWRP(wipe data) install the FACTORYSPRINT.zip reboot device, update prl and profile, reboot, do a system update
It works. I tested it

I'll give this a real-world run-through tomorrow when my new LS998 arrives.

Yeah...it sucks we need this...sprint not allowing access to kdz is a load of bs...it is much appreciated that we have you helping to support us sprint users...i am looking back at my past lg phones now to see if i can find the process of creating a working kdz...one of the people i think in the g2 or g3 forums actually created a kdz using the untouched signed lg files and it was fully flashable to get back to 100% stock...i don't know if too much has changed since then to do this again...but it would be nice to have for some...me...i won't be doing anything that removes my bootloader unlock and root...but those with warranty may want to have that ability...thanks to all that have contributed to making this a great device...i missed root on a level people outside these forums may never understand

Could you tell me if i could switch out your LS998 bins for h933 ones? also on my dump from lgup can i just change _com6 to .bin ?

Right. change "_COM#" to ".bin" should be fine as long as the rsa keys match for the devices you are flashing. Don't flash nougat to Oreo or vice versa

Could you lock the bootloader after this? Or will it show an error?

Bootloader would still be unlocked but the message after every boot would disappear and you won't be able to enter fastboot. (After you do the system update)
I thought after installing the latest update it would lock the bootloader...it didn't, but it did remove the text after every boot saying to lock bootloader and you won't be able to enter fastboot after. Activating developer options will show the boot is still unlocked. It does change the software info to LS99821a instead of US99820a
To lock the bootloader, you could probably flash the other Sprint zip(without flashing magisk ect..) and just sprint recovery or the factory zip. Reboot to bootloader from twrp and lock it that way. Then do the Sprint system update *I have to do more testing tho I don't recommend doing this until it's tested*

I have followed WTF thread for my Spring LS998. I have also flashed the modem.bin. I have working LTE on US99820a. I went to try and update PRL and Profile but clicking the buttons does nothing at all. Is this common? Also, i noticed that text messaging are received intermittently. They come in, in bunches, but only immediately after I send out a text. has this happened to anyone else?
I'm assuming if i flash the SPRINTLS998.zip, it will correct this issue, but I don't want to if there is no need and there is a fix. I want to try out DotOS, but don't want to carry my texting and MMS issues over from my current U99820a setup.

You can't update profile/ prl on US998 firmware(or at least I couldn't). Backup your setup and try DotOS if you already have working lte. This thread is mainly for users to get lte back. I'm not running the stock Sprint firmware. I switched to stock firmware first to get lte working and switched back to us998 rom.
If you wipe data and flash the SprintLS998.zip you won't have any issues. It already contains the Sprint modem, system, and boot. No need to flash the modem from the other thread.

Will flashing the sprint zip only have bands 25,26 &41?? I'm in an area with band 13 also.. Thanks.

If you flash the Sprint modem you'll have all the Sprint bands.
It's just the US998 does not have LTE bands 26 & 41. So you have to flash the Sprint modem to get them. If the LS998 normally has LTE band 13, then you'll have that.

Have any of our few sprint users taken latest update and tried to bootloader unlock and root their devices?...just wondering if they actually managed to patch it yet...

I tested the latest update, it installed. I dumped the modem, system and boot from it. I can make a zip from it later. My bootloader was still unlocked tho. I plan to lock it and test..been putting it off, don't want to get stuck on stock haha. I need my phone this week. I'll test this weekend. After the latest update it removed the bootloader warning and I couldn't enter fastboot but the bootloader still showed unlocked under developer options.

I flashed the factory back to stock.zip and went to settings, system update.
Not worth it imo...I was testing the factorysprint.zip to make sure it worked. I can make a flashable zip later(to only include system, modem,boot)..I don't think much changed. Looks like it was just an update to disable fastboot and access to recovery

The first time I tried the profile and PRL updates they took a while to actually launch. Not sure if yours would if you just waited a bit longer (like a minute). I would try that and then the Sprint zip (that's actually more likely to fix your issue).
