Lg g3 at&t factory unlocked firmware update question

Hey guys, I recently purchased an LG G3 AT&T Factory unlocked so other network carriers can be used. But when I click software update it already says I'm updated (CURRENTLY RUNNING LOLLIPOP 5.0.1) so I assume you need to have an AT&T sim card to update your software.
Is there like any way to bypass that so I can update my phone to android 6.0? If so how? and would I need to have it factory unlocked again?
I'm new to this, so detailed explanation would be deeply appreciated!
Cheers!

The AT&T model does not come factory unlocked. It's a carrier model and has to be manually unlocked. So if you bought it new it cannot be new as the seller would of had to open it to unlock it.
But no there is no other way to do OTA updates on it without an AT&T sim, go phone sim , or H2O prepaid sim.

Could I possibly download the official release rom and install it manually using a PC?

Yes but the latest is KitKat so you would be downgrading. Since its the AT&T model it's tot method only. And the latest tot file is kitkat.

OTA updates won't work with other AT&T MVNOs besides H20?

No it wouldn't work with that.
H2O sims can be gotten for under $1 on Amazon or eBay. And you don't have to add money to activate them.

So if I got a used AT&T G3, I could buy an H2O sim, activate it, get the OTA Marshmallow update, the remove that sim and put in my CC sim? Even if I had to buy the $10 Paygo plan, it would be worth it

Yes you can. As long as the used G3 was not rooted you can OTA update.

The unlocked ones will get the updates just fine. But you still will need an active AT&T sim or H2O sim to get the update.

Hey were you able to install marshmallow on at&t D850 by ordering H2O sim?
Please do mention when you inserted that sim then you were in H2O network range or overseas? (as I am in New Zealand)
and how did you manage to install after inserting sim?
Thanks for helping pal.

Actually, you should get OTA updates on Consumer Cellular. They are my carrier and I have received several updates on my AT&T G3, including one just today. New software version is now D85030p.

Word of caution. Be familiar with how to revert to KK using the tot method. I say this because if the phone has been rooted, and all that was done was uninstall the root app and factory reset, the phone may not take an OTA update as it will read the system as modified. Plenty of discussion on this here in the forums. Also keep in mind that there is no permanent root method for MM as of yet.

I bought a 2015 Moto G instead of the LG G3. Decided to go with something not quite so large and with manufacturer (as opposed to carrier) support for MM. After looking at them "in the flesh" I decided the G3 was a larger phone than I wanted. Thanks for your help.

Not sure why your posting in this thread, CM 13 is not stock or official firmware. You first need to ROOT your device.

MsmDownloadTool hunting

Is it time to start guessing what the URL on https://s3.amazonaws.com/oneplussupport/ will be?
My best guess was https://s3.amazonaws.com/oneplussupport/OP7P/guacamole_21.O.07_190512.rar but no luck.
Edit: Found the EU one! https://s3.amazonaws.com/oneplussupport/OP7Pro/guacamole_21_E.08_190515.rar

OnePlus is definitely using this as the root directory: https://s3.amazonaws.com/oneplussupport/OP7Pro/

Does this mean we can unlock the T-Mobile variant with this?

Yes, this program will literally transform the T-Mobile variant into the international version you can buy from OnePlus directly. There is literally no difference between the two, you get the same OTAs as international version just as if you bought it from OnePlus

Has a password, though.

But now we know the filename. This one is apparently for 9.5.4 on the EU model (GM1913). Can't find one for the other builds. Maybe it works for US/Global/India.

I believe the 6t tmobile version after the conversion could get over the air update. U have to.inject the updates manually. Quote me if im wrong but that was one of thw reason why i didnt convert my 6t.

U should have no issues with OTA, the tool turns ur phone back to as it was in the box, it relock bootloader, u roots and stock recovery, now there are some out there that could be modded to not delete userdata and no relock bootloader which means no incremental OTAs

No but we can at least unlock the bootloader on the T-Mobile version

Permanent SIM unlock can probably be done with fastboot commands after a bootloader unlock.

I should have the US (OnePlus Store, not T-Mobile) MSMdownloadtool tomorrow, with the password. Stay tuned on that front.

Thats only thing I want.
I wont have the tMobile one im in the UK and getting 5G variant and it might be sim locked but want to unlock bootloader and not wait 6 months before they give me unlock code.

I just called OP for the literally the 10th time today.
I told them I don't care about my warranty.. I just want the msm tool and unlock. Bin generator. They said that their technical support team is working on it. They also said they will be sending me an email with either the link for the MSM tool either today or tomorrow.
I doubt they will just give a token generator out but once we Hve our hands on the msm tool. We can sort some things out.

Bought on eBay

Bought the 3 on eBay from a seemingly reputable seller. Advertised as an unlocked device Received yesterday. Updated immediately to q beta. OEM unlock switch is not usable. Just greyed out. Is it because I'm on q or because they sold me an unlocked Verizon phone? Thanks

Pretty much guaranteed the seller sold you a carrier unlocked Verizon phone. Most people do not associate unlocked with bootloader unlocked.

Check the first two digits of the IMEI. If it is 35 it is a VZ phone.

All Verizon phones, including the Google phones are bootloader locked and are not unlockable. Verizon does not want to sell unlockable phones and has not done so for some time.
The only chance is if someone finds a hack to get it done. There are threads here where those efforts are talked about, there has not been my any real progress. If you want an unlockable bootloader you need to by the pure Google Store version.

t-mobile's 8T+, root, and (future) roms

I see there are already rooting/unlocking bootloader instructions for the regular 8T. is there any reason I should hesitate before buying the 8T+?
my main concern is (future) 8T roms may not work on 8T+. but in general, seems like most OnePlus phones eventually get official LineageOS. so should I not worry about it?
obviously it'll be some time before roms are available regardless - that's fine. I'm more thinking about 2 years down the road.

It's definitely 8t+. it's distinct from the 12GB/256GB model that you can get unlocked.

Problem is that even when you do get your SIM unlocked you still have to wait 45 days from date of purchase to be able to request a Bootloader unlock code (according to OP)

Thats for sim unlock. There's no time requirement listed for the bootloader. Only need the sim unlocked prior. So if tforce is willing to whitelist the imei (which it sounds like they usually do if your nice about it) then it should be possible. It can take 2 days to get the unlock file but thats better than 2 years to pay off the device.

No! This MSM tool is just to restore to stock TMO build, for example if it bricked or if you wanna return the device after rooting or switching to international (whenever those will be available) this tool doesn't do what you want yet
Edit: I just realized he even linked you a different one, this is for the international version if it got bricked or anything to restore, there is also a TMO MSM tool, but as I said before there isn't yet a tool that lets you convert from TMO to International, I'm also waiting for it
