[Q] Flashing a T-Mobile Rom into Sprint LG G3. - G3 Q&A, Help & Troubleshooting

I apologize for my incompetence before hand. I've been scouring the internet trying to find a method where I can use my LG G3 for T-Mobile. Would it be wise to flash a T-Mobile rom into the phone? Has anyone tried it? Also, what is the most efficient way to unlock the G3. I've done the shortcut method and I was wondering if there were any other methods. Thanks.

If you are trying to unlock the phone to use with a different carrier, Flashing the ROM has no effect. (You probably couldn't flash it anyway)
It would probably be best to look for a service online that could unlock the G3 for you.

[Q] Permanently locked LG G2

Yesterday i got my lg g2 from ebay. I spent several hours researching how to root my phone, install custom recovery and a custom rom. Eventually I succeeded. feeling proud of my 'accomplishment' (as it was my first time) i went to bed. only to find out that my phone is permanently locked when trying to unlock it!!! I googled for answers, but I couldnt find one. My LG G2 is D802 int variant. running 4.4.2 with cloudyG3 1.3 ROM. Is there a workaround for this issue? I'd like to emphasise the fact that this phone is PERMANENTLY locked so please dont suggest to buy an unlock code. thank you

[Q] Can bad esn sprint LG G2 be sim unlock

a friend of mine gave me a bad esn sprint LG G2 that he bought off on craigslist. It has the ZVE firmware and I succesfully rooted it using stumproot. I install all of cloudyFa's roms on it, but for some odd reasons it won't pick up my tmobile simcard. I go to "phoneinfo" and no matter what I switch it to from WCDMA preferred to GSM only etc.... it just keeps saying "emergenc calls only" So i'm wondering if it's because of the bad esn that's keeping it from recognizing my Tmobile sim card. Anyone can help me?

Try a regular unlock on the device first.
regular unlock?
when you say regular unlock do you mean have the device unlock through Sprint first? I don't think Sprint will give the unlock code because the Sprint LG G2 has a bad esn. If what you mean by regular unlock refers to modifying the software then unfortunately that is something I'm not really good at, but I'm a risk taker - I don't mind attempting to do the regular unlock even if the bad esn sprint Lg g2 gets messed up in the process. Is there anyway at all for you to show me how to do the regular unlock? I saw in another topic about using Rom Toolbox lite to change some stuff, but when I install the Rom Toolbox lite app I have no idea how to use it - it's all very confusing.

I went to the link as you suggested and I downloaded the file that you provided, but it would not let me copy the folder carrier. I follow all the directions that was provided on the link, but when I check the carrier folder on the phone I notice there are only two folders. While the carrier folder on the TotalCMD folder had like 6 folders plus a file.
Hmm, not being a gsm user, I am not sure. Was there any information in the thread of someone else with the same issue.
One thing I think they didn't say was you have to be on zv7 or zv8. Unless further in the thread it says other wise. Still reading.
zv7 or zv8

when I was handed the bad esn sprint LG G2, I checked the firmware and it was on ZVE firmware then I used LG Flash Tool and downgraded it back to ZV8 firmware. I have successfully rooted it also now on the ZV8 firmware. My brother-in-law has a sprint LG G2 and his work for tmobile, but only thing is his Sprint LG G2 has a clean esn/imei and mine don't. So i'm assuming mine is not working because of the bad esn. Oh well I will keep on trying and figuring out how to make it work.

How to Unlock S3 t999 4.3?

Hi to all, im new on the forum, i was looking to find a way to unlock my S3 t999 which has the android 4.3 JB, i got a lot of info but it seems that i only Rooted my S3, i found out that there an easy way to do it whit the Service mode but since i have Stock 4.3 its impossible, was looking a way to downgrade to 4.1.1 but probably ill get a brick, so if there any way that i get some help unlocking my device i sure will appreciate it.
After 4.1.2 I think there is no free alternative available (unless your carrier gives unlock codes for free after a certain time period). The best way to unlock your phone would be by contacting your carrier for an unlock code which usually means paying a fee or using a pay service. I would recommend using your carrier because they will offer better support and this would reduce your risk of getting scammed by a online service.
Help please!
Hi! Where do I begin?! So I have a tmobile s3 T999LTE version. Previously I rooted it because I wanted custom rom on my phone. Then I wanted to sell it so I unrooted it. I had read somewhere that after unrooting I should revert to latest stock firmware which was 4.3...BIG MISTAKE! It's now running on 4.3...LUVUBOH1 and I CAN'T UNLOCK IT! Tmobile had sent me a code which did not work, then I switched to metro pcs and purchased a code off ebay,which was the SAME code tmobile had given me. I now have metro pcs on another phone and when I put in my current sim in s3 it doesn't prompt for code! And no key combos are working due to change in dialer. I am stuck and gave no idea how to fix it. Imei is valid and I'm pretty sure I'm running stock 4
3. Help anyone? Please? ???
Was the phone running a completely stock rom when you tried to enter the code? How many times did you try to enter the code?

LG G4 US99111a

Hi. I'm wondering if I can get some help with this device. I purchased this device unlocked from my local Rent a Center in New York. Since its unlocked, I am using with my servicer provider Metropcs. Here's where im having some issues. Metropcs offers WiFi Calling on all their devices [ have a LG K7 ] as does T-mobile since they own metro. I noticed that the feature is MIA on my G4. I did some research and found out from LG that the phone itself was originally a US Cellular device. I then called US Celluar. I spoke with their techs and was informed that they don't offer WiFi calling at all with their service, but it doesnt mean the phone doesnt support it. Believe it or not, the tech told me that its more or less a software thing. I went through the stage to upgrade the device to Marshmallow, but apparently its not available. I noticed that all US Cellular LG G4's have Marshmallow. Im wondering if theres a root method that might fix my issues. I looked around and didnt see one for this LG G4 US99111a. I only see them for US99110. Can anyone here at XDA possibly help? Any and all info will be appreciated. Thanks in advance.

How did you brick the phone? If the phone has access to the DD commands then you can create the image yourself...obviously your going to brick the phone flashing another phones pre-rooted system img... All LG's on Android 5 can be rooted if you can access the proper commands. If your working with your own image how are you going to brick it???
I say this because I was even able to flash the LS991 TOT and root my phone and its a US991...only problem was it flashed the Modem files and the KDZ does not contain ModemST1 and ModemST2.

Flash LG G7 to unlocked carrier version

Hello forum, I have much experiences with mobile technology and computers however, this has me mind boggled. I've flashed my LG tablets and LG G3 phone to various firmware versions. I now use a Samsung S9+ unlocked version that can be flashed to any carrier firmware at Best Buy with the Samsung reps however, I have a Sprint LG G7 that I purchased for my son and I want to move him to Verizon. I called LG and they told me first that I have to get Sprint to unlock it then I can take it to geek squad and they will flash it for me. I called geek squad and they told me they don't do that. I start looking on the internet and from the looks of it, I see people with trial and error on doing this. My question is this, since this phone is basically the same version as a CDMA unlocked phone and can be used on various other network, why am I unable to find anyone who has easily flashed this model to a full unlocked variant or to a full Verizon firmware flash? I'll pay someone to do this or show me the exact steps without bricking my phone. I mean, I can probably un brick if that happens but I need experienced help from techy to techy. Thanks
