Hello,
I acquired a Verizon G3 as a gift a while back (weird story) but my primary phone has been a GSM Nexus 5 and I have been on T-Mobile service for a couple years now. I used the G3 as a second phone/tablet by just connecting to WiFi and using it for a camera/games/music device. My beloved Nexus 5 has become less reliable and I thought I would just switch to the G3 as my primary phone. I put my T-Mobile SIM card in the G3, manually entered the APN, and to my surprise, I connected to T-Mobile LTE immediately! Awesome! Now, the only thing keeping me from being satisfied with this device is that it is still running 4.4.2. I guess it never got an OTA simply because it never connected to the verizon network.
So my question is, is there a way to get the long-awaited OTA from T-Mobile or is it not compatible? Is my only option to root the phone and flash Marshmallow?
I appreciate the help!

There is no Marshmallow for the VS985 yet. 5.1.1 (35B) was rolled out a week or so ago. If it's flashed stock, it cannot be rooted, but there are pre-rooted custom roms available. Easiest way to go about it would be to KDZ flash back to 10B, root using stumproot, flash TWRP, and then install a 35B pre-rooted custom roms via recovery.
Check the Verizon LG G3 forum for more info.

When I switched over to tmobile about 2 months ago I decided to keep my g3 that I had with att and also got another one with tmobile.
My question is, can I flash tmobile roms with the wifi calling onto that phone? I would like to test roms on that phone first before flashing it on my daily phone
bump.
Just got an AT&T D850. Have been trying most of the morning to move it over to a TMobile flash. However, TMobile only has the D851, which I do no believe will work ...
Has anyone successfully done this?
Be aware of that ATT hardware does not have AWS HSPA like T-Mobile hardware.
I did what this 3 weeks ago on an ATT LG G2 using LG Flash Tools and KDZ file.
After the flash, the device booted up normally with TMobile screen. Yet, nothing worked normally, no signal. I couldn't even to settings as it quit every time. The end is a soft brick phone.

I wouldnt do that if i were you. I mistakenly flashed a D855 ROM on my D851 and now its bricked. No boot, recovery or dowbload mode. So beware.
Only D850 Roms will work for you, no matter what carrier you are on. You will hard brick your phone most likely if you try any other variant.
So far, managed to root my Korean F240L, still running 4.4.2 for now until there's a root for Lollipop. Haven't managed to see any 4G signal in the UK since I got it , get 3G sporadically but the reception is way worse than the same sim card in my old Nexus 4. Network is Giff Gaff (ie O2) , should I consider going for a UK baseband update ?
Right ok, since found out that the Korean version doesn't support UK 4G. Is it possible to change this ?

If the phone doesn't support the LTE bands your desired carrier offers, then no, you're boned.
Think I'm in a similar situation
Got an E986 from Germany running 4.4.2 KitKat (E98620a-EUR-XX), it works great on 3G in the UK but NO 4G at all on my Three 4G Sim card. Tried enabling it in the hidden phone menu - no joy.
I thought I would be able to get 4G working by rooting and re-flashing but by god I cannot get this thing rooted despite my best attempts from trying all the techniques on here
Thought if I downgraded to 4.1.2 then I would have better luck rooting, but can't seem to download a .kdz that isn't corrupted when I try the LG FlashTool

You cant change the bands of a phone by flashing other things. If it doesnt work it most likely wont be able too.
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.
I purchased a G4 h815 with hopes of unlocking the bootloader. It turned out to the the giveaway USA variant so LG will not allow bootloader unlock. Since it was still on 5.1 I was able to put a rooted 5.1 stock build on it using Low Effort Root thanks to this thread http://forum.xda-developers.com/g4/...zw-intl-variants-soon-root-lg-t3164765/page64. My question is where do I go from here? If I put a non-rooted MM ROM on it will I be able to continue upgrading the ROM or will that be a dead end? Should I put a stock ROM on it that will be able to receive OTAs from LG? If so which one do I need in order to guarantee that I can get OTAs? If it is not possible to retain root, how can I insure that I can at least have tethering available? I am not new to rooting and ROMing but I am new to locked bootloaders and new MM security issues. I am a net10 user (AT&T network) since that is the only good signal in my area. I bought this phone for the superior camera, micro sd slot and general good value in a used phone but I fear that it is at a development dead end. Any insights, suggestions or resources that anyone can point me toward. I have searched extensively in these LG4 forums and elsewhere without seeing these issues directly addressed. My next step would be to give up on LG and go with a phone that allows development like an HTC One M9.
Thanks in advance!
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:
