Have bought several "refurbished"LG phones from Aliexpress over the years and apart from a G3 have had no problems when flashing/updating firmware by ota,lgup or lg Bridge. At the moment have v500n20x firmware and if i check for updates in settings am told " using latest software version". Lg Bridge tells me v500n20z is available to update and I checked and there is a v500n20z kdz out there. So has anyone successfully updated these ways? Also would not having 20z firmware stop phone from ever updating to Android 11. Am sure years ago i updated G3 using LG Bridge and all seemed ok until i realized no mobile network coverage. Apparently seller must of modified/flashed modem that worked in my country and update put it back to stock. The V50 v500n all checks out in Aida64,CPUZ and imei checker as genuine but thinking of it now ,if i was going to update would LGUP(Uppercut?) be the the safer option baring in mind it's a "refurbished" Aliexpress LgV50

My Korean version LG V500N has already updated to android 11 just one week ago, my device is with "KT mobile" vendor but I'm using it with Telcel and Movistar providers in Mexico without problems, well except OTG connection, my device is unable to use OTG, no matter how many times I connect via OTG and select file transfer in USB mode it stops connection to reconnect after just a second again in power supply mode

I have a stock O2 UK O3D. LG website says update available, phone says I have the latest version (v10k) which is 2.2 so I run LG updater on the laptop and click its update history tool which says "s/w v21a" as if it thinks I have gb.
I cannot find who provides my updates, it's definitely not O2, maybe if I rooted it I could find who supplies them via a config file or else I will be stuck with Froyo forever

If you are operator locked and in the UK you will get the update december 5th.
It is due 5th of December in UK. However, you can flash the official ROM, see development forum.
According to the operator (O2) my phone is not supported by them for updates, and the phone seller has no idea who sends them. Will wait for december and see.
Thanks
Dave
I am with O2 but didn't get my O3D from them. Up until I flashed it last night it was still on 10D!
So nobody from O2 updated my handset.
I have to wait as if flash phone and mess it up cant replace it
Dave
You can try removing your sim card and selecting another country in the LG updater if your phone is not simlocked by O2.
Flashing the official rom isn't that hard either. I can't get the update either so I just followed the tutorial for kdz flashing and had GB on the phone in about 15 minutes without losing apps and messages/contacts etc.
If you're not sure about flashing then it's probably best to just wait. The update will be provided by LG themselves eventually through the update utility.
Think I will wait, have flashed phones before (put gb on my gt540) but knowing what cwn go wrong I daren't risk a contract phone as got two years til can replace it.

Same problem
I have an open phone in sweden. When uptating my phone i got v10k and i cant get v21a. Every check i updater and outside shows no possible update, but v10k. If i check update history in the updater it says v21a.
It is now a matter for the support and in the hands of the mobile phone expert. They have to solve the problem under the sales contract.
I got mine from a company that sells lots of different phones with various providers contracts so although my sim contract is with O2 in the UK the updates are not and the seller doesn't push ota updates so I have no idea how to find out where they come from.
Although I have rooted the phone now so if anyone knows a system file that stores details of where the update check connects to and replies with it I can check that

I bought a V10 H901 in Aliexpress and the IMEI sayd that was a H901BK. It was with the T-Mobile software and Android 6 MM. In PC it said the H90121j and I wanted to upgrade to 7 Nougat and I put the phone in the PC and after the update with LG Bridge it just bricked. Died and do not back to life. I unbreacked my phone with this tutorial:
https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
The Unbrick H901 SD card didn't work, but this worked.
After that, I tried to install all H901 firmwares and didn't work. So I decided to install the H900 firmware and the phone finelly worked. It's working everything fine with no malfunction. Just the Android back to 6 MM, but with the AT&T apps.
I didn't understand nothing. My phone was a fake H901, because is a Refurbished phone. I'd like to install the Nougat update. Is it possible?

Just check at&t website= https://www.att.com/devicehowto/tut...bystep_KM1134561?make=LG&model=LGH900&gsi=oyB
at&t is just behind as always with updates. The other carriers like Verizon, T-mobile etc just push the updates to the devices without sim card or other crap steps

I have same exact problem with same refurbished phone h90121j I unbricked with the same method but I cant install AT&T software because LGUP says that I can't go from H901 to H900. I can flash any other H901BM firmware but my phone bricks again and again.

You'll probabilly need an Octopus box to reinstall the firmware. Try to find someone who can help you with that.

Yes. I have used this method to unbrick from 9008 mode and get download mode https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
Then extracted dz from AT&T H90021w.kdz using LGExtract.exe
And then flashed dz to phone via LGUP.
It's strange but AT&T firmware is only one that working in this case. On my phone without any bugs, fingerprint working, can install apps from play store etc. Only downside is that you will be stuck on Android Marshmallow but at least you'll get working phone.

Probably this method wont work on korean models without bugs. Not sure about kdz and dz. You can try.
Thank you so much!! I tried for a long time to restore the phone, finally the phone works, YOU ARE DIRECTLY HERO))
I acquired a lg v50 (LG V500n) recently and it came with this version (u + 5g), at boot time this name appears, I was wondering if I can switch to the OPEN version, belonging to the lg v500n from korea.
From what I get reading threads on XDA, crossflashing even within the same region is blocked by LGUP. Of course I would be very happy if someone would correct me as I also own a Korean model with SKT and would like to get rid of the annoying boot screen as well as the bloat.

What I understand is that you need to be in Korea or use a vpn to receive the updates, you can still find them to install from Lgup
if i install any android 10 FW in LG UP (open or branded) it won't boot, I installed hola vpn but it doesnt find any ota so i´m in last fw of android 9....
send me files (lg up, configs and dll)

Did he cross flashed? I guess he just used the same region previous version. Correct me if I'm wrong.
Hi there,
Yesterday I bought a retail unit LG G7 from eBay. I removed retail mode from the phone quite quick but it wouldn't charge up to 100%, storage was almost full, you know the drill so I spent a good 4 hours yesterday trying to flash stock firmware on it.
I tried 5 different KDZs (Korea and USA both Android 8, 9 and 10) and while they all flash with no errors, Wi-Fi doesn't work on any of them and I can't finish the initial setup.
I pick my language, I pick the notch for the second screen and when I get to "Set Internet Connection" I have 'Mobile Network', I tried a SIM already, I don't think this demo unit has LTE and Wi-Fi is greyed out or it tells me "Wi-Fi connection is not ready, please try again in a few minutes".
And sooner or later the phone restarts and wipes itself again.
LGUP tells me it's model g710v10a
Oh and I used this method to flash the firmware: https://forum.xda-developers.com/t/...g7-g7-dual-sim-thinq-except-t-mobile.3915303/
Can someone please point me in the right direction? TIA
Demo model should never be crossflashed as its not compatible with other model's fw. You can flash the firmware dump in qfil for demo model https://mega.nz/file/LokAEKZC#tADaJa0jwdWq6QByg_qsLEZTen_-_zqJXxG-sZEsuFI and restore to that fw again, you can remove demo thingy if you follow this thread https://forum.xda-developers.com/t/lm-g710v-the-lg-g7-thinq-retail-mode-demo-mode-thread.3910502/ related to demo model. What i recommend you is to buy a broken display g7 or the motherboard of it and replace it so you have a normal phone.
I have a velvet LM-G900UM. I would like to enable wifi calling, but the option is grayed out. Software version shows as G900UM20m.
I'm wondering if changing the firmware to one of those listed on this page will solve my problem?
LG G900UM(LMG900UM) aka LG Velvet 5G - LG-Firmwares.com
LG G900UM download the firmware for free! Detailed installation instruction. Video review of the model and its features. User feedback and latest news.
lg-firmwares.com
If so, which would I use? I'm a rookie....totally clueless.
You can try European LM-G900EM Firmware using patched LG Up Tool.
i noticed that under the link that i provided above, there are firmware versions that say "Open" in the description....does anyone know if that indicates lack of AT&T locks in the software?
when i try to run lg up, i get a failure message. i tried using uppercut, and i see the phone connected, select the firmware file, and when I start, it shows progress going to 4% and then the software crashes (windows). I have read other threads indicating a similar problem. i was trying to change the firmware to G900UM20j_00_OPEN_CA_OP_1027.kdz
do i need to do something else prior to using lg up, maybe unlock bootloader? i've turn on unlock and usb debug in system options, and also turned off usb debug....no difference.
i have not tried flashing to the european firmware...i wanted to try the canadian version that has "OPEN" in the name, hoping that it might not have the at&t controls/locks.
