I recently bought a new unlocked AT&T model (LM-G820UM) from eBay using it on T-Mobile. As much as I try I can't get it to update OS nor security updates, they're all factory defaults from April 2019. I tried using the update features, several phone "tricks", LG Bridge (didn't do anything), and my final recourse is LGUP but I don't want to brick my phone so...
Does T-Mobile update unlocked phones? What can I do to update the phone?
If I manually update the firmware must it be exactly for the G820UM model?
I haven't done anything like this for a long time, but I am a bit computer literate.
UPDATE: Here is how I did it:
Buy an inactivated AT&T SIM from eBay. Activate it on AT&T's site where it says "Activate your AT&T PREPAID device" (Sorry, the forum doesn't let me post the link.) There is NO NEED to purchase a plan or a pre-paid card.
Wait like a half or an hour for their systems to update. Insert SIM to phone. Your phone will recognize the AT&T network, make sure you have access to WiFi.
Change the date to a week or two in the future. Manually search for an update under settings, software info. It should find an update ready, it will do the updates in chronological order of release, keep telling it to search for updates until it is done.

There isn't currently any flashing you can do with the at&t variant. Since you're in the us the guides on how to get otas with att on another carrier should work

worked for me. I have cricket too. Pro tip, put the att sim card in, activate it to get a number (shouldn't cost anything), then factory reset the phone. Skip all prompts (except for the wifi) on setup and go straight to the update screen. Hit update, if it says you are up to date, repeat the whole process. I've updated 3 lg g8 phones like this. The changing the date forward thing does work but I feel like it took more time.

I have a problem. I ordered an atnt sim card off of ebay. I went to activate it on Atnt's website. I typed in the information but I got an error saying it doesn't recognize my phone's IMEI number. I tripple checked to see If I typed in the correct number and its correct. But it doesn't recognize my IMEI, and doesn't let me go further. What should I do?. (Yes I do have the LM-G820UM)
Has anyone tried it in a country in America that is not covered by At & t?
Is there any way to save the life of LG G8 G820NO10m device when bricked.? when I made the mistake of modifying the EDL 9pie file to 10Q. please i need help from outside. this situation lasted for me for a week and i have no way to fix this problem on my own.
I was able to update a Sprint device without the sprint sim installed. Connected via wifi and it found the updates. One by one, all security patches also had to be done. Long and time consuming process.
but no sim involved.

Hello All,
I have a verizon LG G4 that was purchased in late 2015 and I am no longer a Verizon customer. Since I now use ATT, I decided to shred the old Verizon sim card and switched to unlocked s7.
Since the phone no longer contains a sim card, when I try to use the verizon software upgrade assistant on PC, while the utility shows that there is a software update for a moment, it immediately switches and says that phone is upto date. The phone number shows up as 000-000-0000 (most likely because there is no sim card in it)
Would you please let me know if there is a way around to get the software update? Perhaps, a way to download the update locally to my PC and then push it to the phone?
Thanks!

hey thanks for replying so quick, so if I was on sprint firmware, and wanted to try any of the others, does that mean I can only go one direction? like once I'm off sprint I cant go back, or are there ways I can get back to my original sprint firmware?

You can with a unlocked bootloader. But to go back to Sprint you need the official firmeware which they do not provide to the public.... I have a G7 had it unlocked, different firmware installed. Had no service, . Tried to flash another firmware and ended up wiith a hard brick.. Got it back to the first unofficial sprint firmware, then had to have Sprint reflash the official firmware for the phone.. What's nice the bootloader is still unlocked.. Right now I would not even try anything. Best bet is to return if able, and buy a already unlocked version, so long as you can use it with sprint.

Man I just bricked the phone, first I tried flashing G710EM using LGUP and Partition DL (Select All) it failed almost immediately, after rebooting the phone it booted straight to Firmware Upgrade mode. Then, I got G710N20f, also tried to flash it using Partition DL (Select all), this time it failed at more than 70% step BackupGPT, now when I reboot the phone, I get the LG logo but after the screen turns to whitenoise like, it seems like it is still in Firmware Upgrade as I can still connect to it using LGUP.
Any ideas how to unbrick it? :crying:

Are you sure it is firmware (bootloader unlcok)? or sim unlock, there is a difference.. If you did a bootloader unlock you will get a waring saying. "Warning your software can not be check or is corrupt, please relock the bootloader". If you don't have this kind of message of this sort, then you just had it sim unlocked.

im just going by the ebay listing. It states"Your phone will be converted to a unlocked firmware version and that i can no longer receive ota updates".
My software version is G710ULM11e and my build number is OPR1.170623.032 and im on security patch level july 1, 2018 and android 8.0. When i go to the update center to check for a software update it states im using the latest version for my phone.
I did try a prl update and update device config and it states profile cant be updated. SprintDM notification shows that it trying update mobile network. it comes on and off every 3 mins or so.
I hope this is enough information to go off of! If you need me more information , please tell.
Also I did contact sprint via chat and they stated i could get my firmware back to stock but its 2 about 2 hours away from my city . itll be a like a whole day trip for me since i don't drive and would have to take a bus. I would love to avoid that.
Thanks!

that problem with the Sprint DM trying to connect every couple minutes is a huge problem with the bootloaders be unlocked you will have to go to Sprint and have them do it it takes about 30 minutes because right now there is no firmware available for Sprint anywhere on the internet. when I get a break from my new job I am going to try and install TWRP on my device and if I do it successfully I will be able to upload some firmware but that's not guaranteed.

Whether you had insurance on the phone or not should not have mattered. Sprint should have flashed the firmware, cuz that's their damn job. They asked me the same question I told them no and they still flash the firmware.

You have to be assertive or act completely aloof. If you are a paying Sprint customer, they will reset/reflash your phone. If no one in your immediate area can help you out, maybe you can mail the phone to someone who can get it serviced (heh I'd happily do it for free but hopefully there is someone a bit tech savvy in your own social network).
Hello all,
I have an LG G8 on November firmware (I think) on Pie, not Android 10. I am looking to update to an exploitable firmware, but don't want to pay for AT&T service.
How do I go about doing this? I can see I can buy AT&T sim cards on eBay, but not sure what to go with.
My phone is also locked AT&T, but it looks like we don't have an unlocking solution yet. I know putting red pocket on the phone doesn't give me updates and still makes it so AT&T's unlock portal doesn't see my phone IMEI.

Unfortunately, there isn't really a way to do anything right now since the pie firmware isn't exploitable. The only thing you can do is try to call at&t tech support and have them add your imei to the update database

It looks like LG installs updates incrementally, so by purchasing an AT&T sim I think I can get to the exploitable firmware just by doing a couple updates. I'll post back once I get the sim
So I have my v35 actually going to be discarded, and I decided to buy a cheap G8 from [email protected] and I am confused about the Android 10 update... Some users reported that if the phone is on Pie and skip all the set-up for first time and connect to wifi without any sim card they have upgraded their phones to Android 10, other suggested that they changed the time zone and it worked eventually, others reported that they got a [email protected] sim card and they inserted and after a couple of minutes or hours the update will automatically downloaded.
As someone who live outside US I import my phones because they are way cheap than here in my country and I have enough knowledge of flashing software as I did with my v35 also that was or it is [email protected] But now I see that the Android 10 kdz is on the LG site for flash? As I had to or wanted to install Android 10 on the current v35 as it is unlocked I had to flash the korean version...
My question is if I can flash using LG bridge the current Android 10 kdz or it's not possible on the [email protected]? Or I need to buy the [email protected] sim card or how the heck it's the correct way to upgrade the phone? I have to sim unlock the phone first or should I have to do without sim unlock?

Sorry, there's basically no way to update. You can't cross flash, and at&t doesn't provide kdzs. The only way to is to buy an at&t sim, but you have to activate it, which costs like another $60, and you need to actually connect to at&t, which can be done practically nowhere outside of the us I think
Mmm even with the official page of LG having Android 10 kdz? They are listed as unknown and CAN, and some of them are listed as US too, just wondering if I had to do the same as I did with the v35, which also as being of at&t and unlocked it was never going to receive the Android 10 by ota. I just flashed the korean kdz and it worked and of course it is different.
https://lg-firmwares.com/es/lg-lmg820um-firmwares/
The thing about activating I guess I can't as I am outside USA and by $60 I could anyway it's way cheaper than paying retail prices here for $800

Ey pardon for insisting but... T-Mobile and Verizon are way easier to update or it's the same mess as at&t version? Saw a couple of them unlocked one of T-Mobile and the Verizon one seems black listed but for overseas in my case works.

I don't know if they work overseas when they're blacklisted; I wouldn't be too sure of that. Those variants should be fine because t mobile and Verizon provide kdzs, so you can always update manually
Yeah I asked on Reddit and people say T-Mobile updates ota and are on Android 10 and of course they advised me never again buy any at&t variant and even Verizon can update also ota.
Hi there, so about few months ago like back in August, I got myself an LG Wing after LG announced that they were going to close the mobile division. I live in Malaysia and I asked help from a friend in India to help me get one and send it over.
After getting it in my hands, and after I inserted the SIM, it says Network locked. I bought the phone unlocked but it turns out, the phone needs to be used with a SIM from the same country, perform a 30 minutes call and then it would become unlocked.
Given that I stay in Malaysia, its impossible for me to travel all the way to India to unlock a phone. That said, is there any way I could perform either one of the following?
- Get the Unlock Pin to be able to use with other network?
- Change the India Official ROM with a different country ROM perhaps?
Thanks!
