Hi,
I'm in the UK and I work in the gadget repair industry. I have been asked to sort out an LG Optimus Big LU6800 that's having problems with the Wifi and Bluetooth. It's locked to a South Korean phone network called LG U+ (No Sim card)
After a couple of hours of research (which has been difficult given that there's not much English documentation or discussion on this phone) I think I've worked out that LG U+ have the phone locked down so that the WiFi and Bluetooth functionalities don't work unless you purchase a data plan with the network. I've also read that they blacklist the phone if the contract plan is terminated, also rendering Wifi and Bluetooth unusable. Is this even possible, or is this what they might have done?
Can anyone help me on this? Or can anyone fluent in Korean do some Googling on my behalf to find this out. I know it's not a hardware problem as I have already replaced the antenna to no avail. (this is my first experience with CDMA phones, I've never seen one before). I can't even boot the phone into developer mode, it seems like they've locked that down too .. meaning I don't actually know how I'm going to go around sorting this phone out.
Hopefully someone can help me, this seems like a good forum.
Thanks.
I got my phone running with a T-Mobile sim, and when I got no service, it switch automatically to global mode and pops a message every time. It's very annoying. Did anyone know how to get rid of this issue? Thanks.
LG G3
Mine has done that too, and once even after I had reinstalled the Verizon 4gLTE sim.
I don't know how to keep the pop-up away, but I can tell it cancel.
What I wonder is what difference does it make, between Global and either of the other two ? Does using Global lock out LTE mode even if T-Mobile LTE is available ?

I'm not 100% sure but I think is more dedicated, and global more generic.

From traveling a lot for work I've gotten that pop up a few times and I'm essence when it wants to switch to Global it's kind of like roaming. You'll get connected up to towers that I don't think you'd normally get on your regular CDMA/LTE setting.
Could be wrong but that's my take on it.

I'm running the phone with a T-Mobile SIM but I get this message quite often because in some areas is not service.

I am currently in sprint, and had a V30 plus phone.
I lost it and cannot find it, so I had to switch to my backup which is a moto g5s plus (bleh)
So I am looking at getting a LG g8x, and had a couple of questions.
1: does the under screen fingerprint reader work with the screen off?
All I could find is even you turn the phone on to the unlock screen. The v30 you can go from screen off to unlock without having to do an extra step.
2: does it do volte? Specifically on sprint.
Volte support from sprint says: G Series (G7 and newer models)
My guess is yes but with these carriers these days you never know.
Anyone in sprint with a g8x that can confirm this??
Yes the fingerprint reader works with the display off
Good day,
I am a proud owner of a LG V20 H910 AT&T for about four years now.
Bought it back in early 2018 refurbished from ebay for about US$185.
I got very good service from this, I learned alot about roms, scripts, etc...
these are the issues I faced...
Very recently, phone started turning off when the battery is around or below 40%
After further investigation and cleaning the contacts, the battery seems to be swollen slightly.
Sometimes I can run it until below 20% until it powers down.
Lately I see it takes a long time to charge from this point.
The phone mic stopped working and gives of static noise/feedback to other caller until you switch to speakerphone then it works fine. This is for mobile calls and whatsapp/duo.
The headphone jack seems to short and stop music and activate google assistant every now and again.
This doesn't happen to all headphones, only some. If you don't move the phone or the cable, it works fine.
Download mode loads, but you get static on screen, tried reflashing with my stock and others but same.
Other than these problems, I totally love my v20 and it is still going.
I wanted to buy either a v50/v60/G8x.
I see LG is no longer making V series.
I like to tinker with mods and roms, what do you recommend
my max budget is ~US$220 and I see I can get these on ebay.
The main thing i like about my v20 is the dac, I use the force high impedance mode as I use it as a music player in my car's Hi-Fi. Is this possible on these units?
I want to go for the v60, what version TMO, Verizon, AT&T?,
I am on Digicel in Trinidad & Tobago. so this doesn't matter but what is the best version to buy for unlocking and future mods/dev.?
I remembered when I got the AT&T version of my v20, it never came with the Music app, and I only recently solved that issue.

Personally I went with the U.S. Cellular unlocked version.Or,you can go with the T-Mobile version.Prefer it be unlocked,and the reason I say those 2 is because at least the firmware is downloadable unlike the AT&T version.But,there is a Qfil copy of the AT&T version in the Q&A post.From my readings they're all IMPL locked and I haven't found away around that yet.
I would like to know too. coming from a v40 that i bought for $300 and it lasted 4 years... I hope to do a similar run with the v60.
Not too worried about updating past android 11. But it does kinda suck the security updates stop at June 2021. My v40 is stuck at 8/20, and I'm already noticing some apps dont work with Biometric anymore.
It took many years before the v40 was finally moddadable to lineage... and I'm sure someone will figure out the v60, but I also worry that WIFI calling won't work if it ever gets lineage.
That said, if I am on ATT, and want to use WIFI calling, I should buy an ATT branded model, correct? If I buy a global model, and run it on ATT, it likely won't work with WIFI calling?

Yes,if you're on AT&T most definitely get the AT&T branded v60.With my V60 USC device it wouldn't make or receive any calls when the 3g shutdown hit.I had to cross flash my V60 with a Luns backup and that's the only way it would dial in and out again.I even went in to the engineering menu and enabled all the settings perfect for VoLTE and it still wouldn't call out.It's not IMEI specific either.I'm still trying to figure a work around for it,but nothing as of yet.
Ok. I just bought the lm-600am version
Hi everybody. I'm new here. It looks like this is the place where the battle is raging against the poorly handled 3g sunset from AT&T. I need your wisdom and guidance.
Background: March/April 2022- I was on AT&T prepaid with an LG G8 G820UM, happy as a clam until The Sunset happened and I could no longer make phone calls. Spent a good chunk of time in the AT&T store and on the phone with customer service but no one could get it to work even though it was on the approved list. Finally gave up and had to change devices because I needed a phone. Ended up getting another LG phone (because they are great) LG V60 ThinQ LM-V600AM. This worked out of the box with the AT&T prepaid sim card on android 10 for months with no problems. I switched to Red Pocket in September, partially because I was still salty with AT&T and the terrible way they handled The Sunset, and that sim card worked fine as well. 5G, calls, texts, everything. Until yesterday... *dun dun dun*
Somehow I was forced to update to Android 11 via a pushed software update from AT&T. Sadly this broke VoLTE and calling on my V60. Tried rolling thru all the rest of the updates available and got up to Android 12 V600AM30d. No luck. Still no VoLTE. Tried messing around with the Hidden Menu. No luck either. So now I'm looking at the possibility of doing some sort of rollback to Android 10, or some sort of Crossflash on the V60 (or on the G8).
What I want to know is: Who has actually gotten their LG V60 or LG G8 to work properly with VoLTE reliably in 2022?? What carrier?? What software flash?? And most importantly, how do I replicate it? Tell me your success story. Mine is a story of failure and clinging to LG because I like their phones but AT&T apparently doesn't lol.
Thanks for listening.
Yeah it's a crap. ATT dialer is locked down and so is BAND service menu. Something not right w/ Phone info prob b/c ATT lock down hoodoo. I'm on LMV600AM30c A12 Sept2022 and had to edit build.prop . set ro.telephony.default_network=26,11 (26=NR/5G,LTE,GSM,CDMA & 11=LTE Only) for T-mobile. On stock ROMs seems no 5G. I debate if it's truly avail but got 42.xxM on LTE this morning. I think I am going to go back to GSI ROMS. It's PIA 2 erase data every flash. Shame can't share or split /data & switch between slots. GSI actually worked better! There is a thread for restoring . I cross flashed to T-mobile and was fine. Updated & screwed everything up bad. This uses QFIL & "LUN" backups or chunks. IMO think LG would release more tools or remove damn region locks. My savior was here:
LMV600AM Restore/Ugrade Guide
This restore process is intended for the AT&T V60 (lmv600am) model and will WIPE your data so back it up if you want to keep it! This process will restore the lmv600am to original factory state for the AT&T v60 v20q build (a11). I’ve dumped all...
