Hi, my G981A is US, Tmobile carrier. It crashed on me yesterday, is caught in a boot loops, and I am trying to restore it. I have found the Odin software and am able to get it to recognize my device, however, I am unable to find the Tmobile firmware, only AT&T. Does anyone know where the T-mobile firmware might be found? Device is paid off, so I think it is unlocked. Am a bit of a novice at this...just trying not to have to get a new phone if this one can be brought back to life.
Phone is exclusive for AT&T. Yes you can have it unlocked and it will work with other GSM carriers, but there are no Tmobile/Sprint/Verizon variants.

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?
I got this phone off ebay for a deal 330$. My plan was to root and install an aosp rom.
I have rooted the phone but cannot find anyway to install twrp. Seems like all the twrp recoveries and custom roms are for tmobile and international versions
i was not aware when i bought this phone that it would be a us cellular version the ad did not say
anyways what are my options? Is it possible to get an aosp rom on this version of the phone any advice would greatly be
appreciated
Unfortunately there are no options as of now. The bootloader is locked and there hasn't been a workaround discovered for it yet like for other devices.
At best you can root and flash xposed on the phone as long as it has Lollipop, but as it looks now, you won't be able to keep root if you upgrade to Marshmallow.

thanks for the reply, i can stop searching like a fool lol
will i even get the marshmallow update, i have a us cellular version running on att network
The US Cellular model will most likely get MM soon, but if you're on the AT&T network, you won't get the OTA. I'm not sure if you would have to put a US Cellular SIM back in temporarily to get the OTA download, or if you could just remove the AT&T SIM and download it over WiFi. Otherwise, you could just get the kdz when it comes out, plug into your computer and force the update that way.

yah but even with the mm kdz file comes out it will be for us cellular and the phone will become carrier locked and i will have to go thru the hassle if getting unlocked. btw my firmware version is us99110a i bought it off ebay. the seller did not specify it was under any network just said network unlocked. but like i said my firmmware version is us99110a which i believe is a us cellular firmware
US991 Marshmellow
Hi Guys,
I am having a real issue here after reading this tread. I recently upgraded to marshmellow but my data stopped working. I cannot get the H+ anymore. I need to go back to lillipop. I am looking all over the internet trying to find out how i can roll back. i even factory reset the phone but is goes back to marshmellow. do you have a clue how i can do it?
I asked around and they directed me to http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
My software version is US99120c.
Can I get help rooting the 10a? Every tutorial I see is 10c and I can''t update mine.
So I just switched to T-Mobile from Verizon and kept my Galaxy S8+. Obviously, I cannot do the system updates through the phone anymore. Therefore, I wanted to know if there is a way to flash the T-Mobile firmware so I can operate the phone as if T-Mobile issued it.
If that is not possible, any suggestions?
Thanks!!!!
I'm sure this is a good place to start. Please research and read through good before proceeding. I almost screwed up my phone going from Verizon to unlocked.

I switched to AT&T on my Version S8 plus. I just updated to the latest Version update by taking out the sim card, turning on Airplane mode and connecting to wifi. This allowed me to take the update.
I'm sure you can flash to another carrier's firmware. Take a look here:

Hello,
I have called Sprint many times, after they keep telling me it is unlocked domestically and internationally, I finally gave up. The phone simply says to contact sprint to unlock. I have no idea what to do. When I press UCCI Unlock it gives me an internal error(407). I tried flashing unlocked firmware (U1) But it does not work on that either. Tried booting up with T-Mobile sim inside, still same result. What to do?
Please help!
I had the same problem. I did a factory reset of my phone, and afterwards, the phone was automatically unlocked. For me, it seemed like a firmware bug.
Hi all. After the phone get unlocked, flash the U1 firmware and you'll be just fine. On the U1 firmware, T-Mobile is the only US carrier network that utilize the full potential of the U1 firmware, Wi-Fi calling and VoLTE. Verizon second with VoLTE, Sprint and AT&T no ? good on U1 firmware, only standard U firmware. Happy flashing
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
