Update to exploitable firmware? - LG G8 Questions & Answers

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

Lg g4 us911 10a (us cellular lg g4) what are my options after root

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.

New LM-G820UM (AT&T) purchased from ebay. Using on T-Mobile and have update question
Hi all,
Grabbed a G8 Thinq for my son off ebay (which scared me but it was cheap). It's an AT&T variant but it's working just fine with T-Mobile. However, the security updates are from July and I'd like to update. I tried LG Bridge and get a "cannot check software version" error. Before I send this thing back I wanted to check here. I understand that OTA updates are super slow to arrived when you unlock and switch carriers but will I ever get one? Is there another way to update this thing?
I'm pretty Android savvy but just haven't messed around on here since my Nexus 6P days. Thanks!

Are AT&T KDZs even available? I can't find them anywhere that doesn't look like a complete scam site.

AT&T is known not to release KDZs ever, and to only provide updates to postpaid AT&T customers. I assume that's true with G8 as well. I saw those unlocked AT&T G8 on eBay for $320, but I wouldn't expect any updates, nor would I expect warranty to be honored.

T-Mobile is pretty good with updates. I have T-Mobile V30 on Red Pocket GSMA (AT&T MVNO) and receive updates.
But T-Mobile phones are very hard to carrier unlock. They can only be unlocked with a T-Mobile Device Unlock app, which queries T-Mobile servers for approval. If the phone is relocked (such as after LG repair, or if you get a warranty replacement) you won't be able to unlock it again unless you're a T-Mobile customer and/or have had the phone on their service for some time (40 days postpaid, 1 year prepaid). It can't be unlocked with a code like other phones.
Like AT&T, Sprint also doesn't release KDZs, but as noted they are less restrictive about OTA updates. T-Mobile and Verizon release KDZs.
Carrier phones generally suck for the same reason that carriers generally suck: Everything they do is always designed to suck you

The T-Mobile V30 has official bootloader unlock, as the only North American carrier model. I believe the same was true with V20: Just Enable OEM Unlock in Developer Settings, boot into fastboot mode (Vol- while inserting cable with phone off) and enter fastboot oem unlock. The problem is the bootloader is neutered, with fastboot flash and fastboot boot commands stripped out. So even after BL unlock fastboot cannot be be used to flash or boot TWRP. But it still relaxes the secure boot chain. So once @runningnak3d found a way to flash TWRP using Download Mode (laf) we were golden.
Of course that laf vulnerability is long since fixed. And I am sure somebody must have already checked if the T-Mobile G8 has official bootloader unlock like earlier LG phones. Right? Or are we just assuming it doesn't because other carrier models don't? I only began following the G8 threads recently, so I wouldn't know.

No g8 has it

LG G8 [email protected] Android 10 update outside US...

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.

Can someone tell me what version of note 10 ive just brought?

Hi guys just got a new phone supposed to be uk unlocked sim free brand new.but its weird
The service provider sw ver dont look english to me
SPR/XAA/VZW
I have my ee sim card inserted and it works to make calls. But there is a weird notification saying OMADM activation not completed
Also says LTE on the screen something I've never heard of or seen here in england we use 4g volte.so I'm confused also the software for uk phones are BTU/BTU/BTU OR XEU/XEU/XEU
And last the box is weird as it says unlocked by Samsung and has a warming saying reproductive harm I was thinking wtf is this phone.
Also it says Qualcomm on the top on a sticker,we use xenox version england
Ps I brought it from Amazon uk
none of it of sounds like a uk version. more like a us one.

Today, we'll explain Samsung CSC codes. Besides, we also have a list of CSC codes or region codes with a method to change CSC on Samsung.
www.droidviews.com
Is it new?
Yes from amazon uk
So this phone cant be used here in England then other than making phone calls ?and how do I get uk firmware onto the phone?I'm a noob and not good with computers
Also changing the csc codes to uk what will that change?as we dont even have the snapdragon model in england?so would there even be uk firmware for an American phone?
Google tells me spr means sprint and that's the first code of the 3
Vzw looking on google means Verizon and that's the 3rd code so the phone was originally a Verizon locked phone.thats was unlocked and flashed with sprint fw, because the second csc code says xaa and apparently that means unlocked.
So what does this mean for me a uk user.luke I said in the uk our phones are BTU/BTU/BTU or XEU/XEU/XEU if there uk and unlocked
If you have a active sim, try inserting it.
It should come online.

How can I flash uk xenox firmware onto an American snapdragon phone?.I'm a beginner when it comes to this.as I only buy uk phones as I'm in the uk and it seems complicated flashing stuff this handset is a u version and I want to make it the f version
You cannot flash UK firmware on your US phone.
Just return it to Amazon, claim full refund as the product is not as advertised: no UK unlocked version, not new. Also screenshot in post #8 refers to firmware of a Note 9, not a Note 10 (N960 is Note 9), this makes this phone even more suspicious...
Return it. There's a lot of bs going on with sellers of this phone. This has gotten really bad. Amazon, saw some deceptive advertising there recently for this model and the N20U.
Best to contact the seller on the phone first; no phone contact, don't use. Make sure you are given full specs on their site and it's compatible with your country/provider.
Buy only a new one if possible. Used ones may be running on Android 11, you don't want that!
I was able to find a reliable US vender and got a new umlocked 10+ 256gb/12gb Snapdragon about a week ago for $800. It was as advertised except due to its manufacturing date is running on Q not Pie. It's a keeper.

Oh sorry it's a note 9 i apologise.so if I cant change it to a uk firmware is the phone useless to use in the uk other than to call people?because my sim card works to make calls
Also OMADM activation not completed message is pissing me off
What does it even mean.i think my phone has sprint firmware on it?how can I change it to normal unlocked firmware so it's nothing to do with sprint I cant stant that OMADM ITS MAKING ME MAD
And Verizon is what I think the phone was originally.
Last thing the phone was sold as brand new sealed but it's not even in the correct box the phone I have is 128gb not 512gb
And it had a sealed sticker saying euro sim only but the phone is American? I think the box is fake ?as it looks nothing like any note 9 box I've ever seen
I'm going to try and flash the phone the phone is currently csc SPR/XAA/VZW boot loader 5 I've just downloaded android 10 also on bootloader 5 ovbisly the XAA VERSION will it work or can I only download and flash SPR FIRMWARE?
as I'm trying to get rid of the MADMEN activation not completed message

It's not impossible but if you are not experienced with better get it back, it doesn't worth the try, you can end by messing up completely.
I've flashed phones many many times before normally when I update the fw via ota and then regret it and need to downgrade back .this phone I just flashed but the start button wouldn't work because I was trying to flash XAA VERSION and not the SPR VERSION .I guess if I was to follow a guide on changing the csc from SPR TO XAA then flashing will work but what the point i wanted a uk brand new factory sealed sim free handset like I paid for
So this pos phone can go back to the scammer on amazon.its a discrace they are making fake seals on the boxes.using fake accessories and lieing saying the phones are uk.the average person would fall for this lies because the phone is unlocked my uk sim will work but you get that OMADM pop up and it's a nightmare.plus I doubt half the functionality will even work.

Any Guide to Unlock Bootloader or Change the Official ROM to a different one?

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!

You don't, unless you hopefully get lucky and its factory bootloader unlocked. There's no way (yet) to unlock the bootloader to root every lg wing, demo or not
Don't buy a demo model unless its just a phone to play with. Not a good every day use phone
