LG G7 - no OTAs after unbranded firmware. Change IMEI? - LG G7 ThinQ Questions & Answers

Hi, I just got a LG G7. I'm from Italy and my G7 is TIM branded. So, I flashed a brandless firmware, but that prevents me from getting OTA upates. I can't even update with LG Bridge because my IMEI is for a TIM branded product. I have to use LG UP to manually update the phone, or flash TIM firmware again to get OTAs.
TIM Italy's G7 have an IMEI like like "355775092x", while brandless G7s have "3557750904x". Is there something wrong if I change my IMEI to 3557750904x and use random numbers after "x" to get updates like everyone? Would it even work?

Changing IMEI is illegal and the servers from LG know that the IMEI doesn't match the firmware. Thats why you can't update. Your choices are to continue updating with LGUP or go back to your firmware

It's not illegal in all countries. I wonder if I could use an IMEI that can receive updates without using LGUP isntead, but also without risking that my device is blocked or something.
I also don't understand why LG decided to block updates to people with IMEIs like mine. These devices contains apps from my carrier and some of them replaces what LG stock apps do. So, I wouldn't block someone trying to get LG apps and remove the carrier ones... whatever.

proof of your statement?
don't know where you live but in italy is not illegal at all. Probably the same is in all europe.
how do you plan to change it? with root?

back to stock brand firmware or flash to the last full updated firmware

How to change region/country? (like CSC in samsung)

I have few LG G3 phones.
I tried to flash some hebrew firmware, that working for other people but not to me.
The thing is this firmware contains a lot of countries. like the csc in samsung devices. (I openned the firmware and saw it inside the cust.bin)
It seems like only phones bought from the official importer, can use this firmware, but other phones stuck on the original region after the flash.
Is there any code in the dielar can change the region?
I know in samsung there is *272 or some apps can do that, but i can't find any thing like that for LG Phones.
Thanks.
AFAIK LG's server recognize your phone firmware by its IMEI. With others LG's phone I used a method the emulate LG's server to flash firmware from another region.

The flash i'ts not the issue.
The same file on other phone work fine, but because my phone is not from in israel after the flash it stay on different region.
Did you try to edit build.prop ?
Find this line and edit the country code.
ro.build.target_country=XX
XX=Country code
From my experience it's working on LG's phones, but I don't know if it will work on the G3, so do it on your own risk.

Didn't work.
Any way i need solution without root, must be some service code.
Actually it's not a few phones, more like few handred.. and root is not an option.
Thanks anyway.

Latest Software for -G710ULM?

Hello, I just bought a G710ULM off the bay and verified the model before purchase. I received it and the software verifies it's a G710ULM but a IMEI check shows it's a PM (Sprint). So the software is still on V10b with no updates coming. I'm thinking this is because the update checks the IMEI and sees it as a Sprint device even though the software says G710ULM. I see a version on LG's site for 11e, is that the latest version? Trying to figure out if I'd been duped. The seller is a MAJOR seller and I'm thinking they are getting these as new Sprint units and LG or someone is reflashing them. I might be all wrong but 2 different IMEI checkers say it's a Sprint.

G710ULM owner here on Project Fi, the latest version is M10g. Updated to it about a week ago. Your phone may just need some time, or you can try using the LG Bridge software on a computer to update the phone over USB. Otherwise, it may just be a carrier thing.
I tried Bridge but when I check for update it gives an error. Wondering, when you check you IMEI does it show up as a G710ULM ? thank you
I got the same problem, got it on ebay, In settings the model is G710ULM, but the real model is G710PM. I also try updating via LGBRIDGE i aslo get the same error. Trying to get a KDZ file but i just cant find one and i don't know if putting another region firmware would work. There's a youtuber that had sprint LG G6 and just changed the Firmware (used one from canada, it work and also UNLOCKED all bands for world wide use).
Same ebay phone Same issue here with no s/n showing hardware is fine unlocked running tmobile usa.. Signal seems bad. Never see 4glte icon only 4g , H, G. Hopefully we can flash to some other firmware to get lastest update.Right now running v10b-Lao-COM firmware i guess thats sprint rom

I did flash mine, had the ULM software with SECURITY PATCH MAY.... What i did is download ULM 10g file from website, used LG-UP to flash it, But first you have to create a DLL file for LG-UP for this to work, if not you going to a error on LG-UP when you hit START.

Yes, the G710ULM firmware 10g that's the project FI(I used another link, not the same you posted, but it should work). I was running the same firmware V10b-LAO-COM, The project FI, was the only one I could find (ULM), so that's why I decided to use that one and because I read on Google that those phones are unlocked. I don't have the steps, but I could make a post in a few hours. And also it's still unlocked, using it outside the US. (I got this one on eBay unlocked version, but it's Sprint).
Does it work with Sprint now? I have the same story - bought "unlocked" g7 on eBay, shows G710ULM in settings but IMEI shows as Sprint phone.. Was working on Tmobile but when I activated with Sprint it doesn't read the SIM.

Well I think it really depends on you, maybe you should return de device, if Sprint doesn't work.... On eBay it said "UNLOCKED". So if it does not work just return it... I am using the phone outside the US.

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).

AT&T LG G8 - Want to flash stock firmware, possible?

AT&T LG G8 - Want to flash stock firmware, possible? Trying to use it on Google FI and it seems hotpot and many other features aren't working. Phione is paid in full and unlocked. Factory firmware currently.
I want to flash my phone
So you're trying to flash stock on top of stock?
The request is to see if you can flash a bare LG unlocked ROM that comes with factory unlocked phones onto a phone that came with a stock AT&T ROM. The Att phone has now been carrier unlocked, is used on a different network, so the Att specific apps that replaced stock apps no longer work.
I was also wondering if I could do this with my Tmobile G8; unlock the phone, then flash the unlocked LG OS instead of the Tmobile version. My goal is debloat, and to be able to have the original Android hotspot app. Not to mention get rid of that terrible pink, loud, annoying carrier startup splash.
Also, I wonder if security updates would come faster when strait from LG instead of the carrier.

Let me know if you find a debloated is for a T-Mobile g8
Has anyone figured out any method that actually works for just flashing firmware to the g8?
Unlike Samsung phones where you can flash other firmwares via ODIN I don't think this phone has that ability. If you got to the ROM/Development section there are threads where people posted firmwares but no instructions on how to flash.

We can actually cross flash, but we need a modified lg dll to fool lgup into letting us flash any firmware.
I have tried just about everything I can think of to get this thing to flash. I saw some people using lgup v1.15 via the command line but that didn't work either.

Hello,
I've tried to flash another firmware on an AT&T LM-G820UM10i with LGUP and a firmware found on lg-firmware.
The LGUP restarted the phone in Firmware update mode, then on LGUP, I got an error
Error 0x5319, Not allow to change the device.(ATT_US->OPEN_CA)
So I've unplugged and reboot the phone. Still working.

that just means one of the unit was not activated on Sprint (usually once activated Chameleon then kicks in and adds all the sprint stuff or boost depending on the MVNO)
I have all the necessary data and the LG DLL in the LGUP folder to put any ROM released, I have an LG G8 from AT&T, I am not within the United States but I am afraid that by modifying the ROM (KDZ) they will not work for me some things like 4G or some functions inside the phone, to specify live in Latin America, if someone helps me pass the LGUP data through Google Drive

You can't cross flash
WHY? The hardware comes with ****ty bloated software, which I did not pay for and want off the ****ing device

Because the G8 and all newer LG phones have security measures to prevent cross flashing.
Many bloatware apps can be Disabled in App Info Settings. The rest can be removed with ADB shell "pm uninstall". Google it.
It's best to never ever buy carrier devices. There's a reason they're the ones sold with a discount :cyclops:

The Sprint LG g8 is recognized by lgup when it's on leaked beta. It's possible they haven't built in security measures yet, I'm going to try cross flashing

Update to exploitable firmware?

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
