How to Update to H90021x w/o AT&T sim - AT&T LG V10

I'm using AT&T mvnos, need help.

I have Cricket, and I don't think we get H900 updates. It's a bummer. Maybe visit AT&T store? Perhaps they can throw in a sim for you.

Use Bob Miller's thread. MAKE A BACKUP FIRST. You will lose all data as well as root if you have it. But it will NOT interfere with an unlocked device

Is AT&T sim necessasry for ota update and rooting?

I am a complete noob and this is my first ever post on XDA. I have searched the forums but unable to find it. So here are some of my queries.
I am using at&t one x, sim unlocked and I am using it in Pakistan with Waridtel. Now when I check for updates in at&t software update, it says service unavailable (because I m not using at&t I guess). So does this mean I will not be able to update it unless I put at&t sim in it?
The other query is all the methods which I searched including one click method and manual ones have a step where one has to check for update. But as I cant have it because it says service unavailable, does this mean I will not be able to root unless I put at&t sim in it?
Sorry for being so dumb again but help will be highly appreciated. I have attached couple of scrrenshots of firmware and baseband etc.
Regards,
Remove the sim card and try again using wifi. That worked for someone in Japan. Just remember not to accept the update. There are instructions for how to proceed.

[Q] OTA updates on an unlocked AT&T G3

Hello everybody. This is my first post here in XDA. Please note that english is not my main language (I'm from Argentina).
I plan to buy at amazon the AT&T G3 model (D850) that has the same LTE bands that will run in my country. I will unlock it by IMEI code in order to use it in one of Argentina's cellphone companies. Unfortunately, international model D855 that is factory unlocked doesn't support my country LTE bands. I have doubts about the Android OTA updates after the unlock. Do I have to wait until AT&T releases Android updates or will I get that direct from LG? Also, what happens with updates with unlocked AT&T phones (by IMEI code unlock) running abroad on different cellular companies? Will I get updates from AT&T or I will be stuck with an old Android version?
Thanks in advance
Unless you are using an AT&T sim you won't receive ota updates from AT&T. Since the phone is a branded AT&T device you must receive updates from AT&T.

Is there a way to update Android in my situation? I saw there is a method through RUU to flash LG updates.

Probably due to ST being an mvno of att. There are numerous threads for numerous devices with this same question as the op, the answer always being the same.

SIM Unlock
If you have your phone paid off and/or have had service for a few months, you should be able to get the unlock code and instructions from TMo. They provided me with the aforementioned info without any pushback. Just call their support number or hop on chat and they will help you out. Also it's free

Bootloader and sim unlocked?

I am thinking about getting Tmobile galaxy s7 to use on Cricket. Can anyone tell if it's sim and bootloader unlocked? I think tmobile s6 was unlocked bootloader and sim.
Thanks.
SIM locked, bootloader unlocked.
SM-G930T 6.0.1
SIM lock doesn't happen until a SIM is put in I believe. That said if you put the Cricket SIM in first it should lick to Cricket.

That's what people are saying, but T-mobile has the app lock on their version. That is part of the software that ships with the phone. Don't believe everything you hear. My SM-G930T came locked to T-mobile.
I'm in the same boat, getting a tmobile s7 for use on cricket.
Unfortunately, it'll come locked, and you'll need to keep it on the network for 40 days before they unlock it for you.
And yet another person on that same boat...
Hopefully we can find a company to remote unlock it. If anyone finds a company that can remote unlock it for a reasonable price, hopefully they can post in this thread
Just because a recovery that isn't meant for your phone can't be flashed on this and because it says Qualcomm secure boot enabled which almost every QC Samsung phone has said does not MEAN THE BOOTLOADER IS LOCKED!!! MY GOD PEOPLE! The tmobile S7 is bootloader UNLOCKED and SIM CARD!
It is as simple as that!!!
Nevermind
Confirmed it with them! http://forum.xda-developers.com/tmo...r-unlocked-t3335224/post65803692#post65803692

Sim unlock is very possible, mine is. You just use the device unlock app by T-Mobile. But no one, I mean no one, on any USA variant has an unlocked bootloader. Unless they work for samsung or simply aren't sharing.

They are equal. Nougat beta doesn't have root. There is a root guide in general. Be sure to follow all steps. There are important ones to avoid lag and battery drain.
