I bought an used lg g4 H815 with someone. After sometimes I realised that it stucks and does bootloops. Then I decide to flash it according to websites which host firmwares for downloads. But, after that, It says "current version is not available for user. Cant find matched cust for NT-code mcc, mcc, subset". Now the network doesnt work on it. I'm a newbie and in spite of my reasearch I cant do anything to solve it. I flashed an european rom, android 5.1 according to my model. The first time I flashed it, in download mode I saw there were only words written in Korean.
Please I need your help. Dont ignore!

Hi there,
I just bough an LG Flex 2 (H955), but the phone is Vodafone branded, thus the firmware is a little behind (still has V10c).
I tried to flash a North European version 10e, but the firmware did not change, although no errors showed up during the process (except a server error but the process continued). I tried to flash using LG FlashTool 2014.
What am I doing wrong?
The phone is running on Polish Orange network, on the box I found that is is a H955 VFD2 variant (whatever that means?).
New firmware wont help. Its piece of **** and nothing will fix it. I wish I never bought it.

It is normal.
The branded phones always indicate a less version, but this is the same version of software.
normal --- branded
V10c --- V10b
V10d --- V10c

Ok, but can I actually debrand the phone in any way?
Is there actually a point to do this? Will I get the software updates faster?

You can delete programs/start screen of Vodafone, but no the version. (system/op directory? I not sure. backup!!!)
When LG launched an upgrade, you upgrade with LG FlashTool 2014 and you do not have any problems with OTA
I assume I have to wait for a Vodafone firmware to be released?
I tried to flash one of the firmwares from the first post here:
http://forum.xda-developers.com/g-flex2/general/official-lg-h955-phone-firmware-t3090920
The process went fine, but the firmware did not change. Can there be a lock of sorts in place?

Sorry, I did not read well the versions.
I followed these instructions with the version V10E (NORTHERN EUROPE Edition) as shown in the phone as V10D. My phone is Orange Spain. You don´t need wait to Vodafone version.

Same here, tried the guide posted by @grauone, but with no effect.
Still shows v10c.
Sorry. I do not know what to say. it sucks
This also applies to Lg G Flex 2,so I literally copy and paste it here
This was not written anywhere specifically on the LG G4 forums that I could find. But every flash-addict needs to be warned. It is something you want to know before you continue tinkering.
Several users (myself included) have made the unfortunate mistake of attempting to downgrade their bootstack (for various reasons) to a former version.
DO NOT DO THIS (at least for the USA T-Mobile H811 version, and possibly other USA versions, per @autoprime)! It will result in a hard brick! Specifically, this results in the "Qualcomm QDLoader HS-USB port ( 9008 )" error. Connecting your phone to a PC will pop up with this active connection, but nothing else. There is no download mode. There is no publicly available fix as of yet.
There are reports of this happening both through KDZ restore as well as flashing bootstack .zips.
Yes, an official KDZ image can BRICK your USA phone, if you try to rollback.
This is in stark contrast to other manufacturers (i.e. Samsung), where the attempt to flash an older bootloader/modem/radio will simply fail, but your phone is not bricked.
I have conferred with @autoprime, who confirmed that with each OTA firmware release (on T-Mobile it was 10H, and now 10N), the version # increments. Flashing a lower version # will result in brick.
I have searched far and wide for a DIY fix. Without the proper firmwares in the right format, as well as the right flashing software, your phone is done and must be sent in for LG repair.

Autoprime says:
I have checked the most recent international builds and all are still on "v0". Tho that could always change in the future... but as of today... "v0"
The original out of box Tmo h811 version was "v0"... after the first forced OTA it became "v1"... as of 10N it is now "v2".
I do not have access to the latest AT&T, Sprint, US Cellular or Verizon bootstacks (seems there are no new KDZ's for them and no one has dumped the files) so I cannot confirm if AT&T, Sprint, US Cellular or Verizon's latest OTAs also move it up to "v2" or if still on "v1".
Actually.. I'm not even sure if Sprint, US Cellular or Verizon got a 2nd OTA yet.. but I know AT&T has "10i". If any 10i users who are rooted could dump the bootstack for me and send it over I can confirm.
Latest I know of for Sprint is ZV5.. thats "v1". US Cellular.. not sure.. but 10C was "v1". Verizon... again.. not sure what latest is.. but 11A is "v1".

http://forum.xda-developers.com/g4/general/psa-warning-try-to-downgrade-g4-t3197675
As the name suggests, I being a very smart person decided to flash a KDZ for the T-Mobile version at 25% battery. It either died during the flashing or wasn't going to work in the first place, about 80% through the flashing the screen went black and I was left with QHSUSB_BULK. The screen does not turn on, also while charging the LED doesn't turn on. Can anyone help me
P.S, I am with Wind
Did you tried entering the recovery mode?
,,
first of all, can you get back into download mode, or boot into safe mode at all? If so then it's definitely not a hard brick, which means that you might have some hope. So long as you can get it back into download mode, and if you're able to find an appropriate KDZ for your specific model (H636), it might be possible to undo the damage and get your device working again.
But from the sound of it, with the fact that your display doesn't come on, nor does your LED light, it sounds like it's a hard brick. Which means that you're now the proud owner of an LG branded paperweight. If you tried flashing the KDZ from the unbricking guide on the forums, it will only work if your device is already a US T-Mobile or MetroPCS model (H631 or MS631, respectively). Any other model (like the US Boost/Virgin/Cricket models, or non-US variants) will just result in failure, and ultimately a hard brick.
Mines also brick
Hello my lg g stylo also went hard bricked but mine's is a us how can i fix it do i have hope.
Hi I have a canadian LG G stylo (H636) with fido mobile. I want to install a custom ROM as I am sick of the stock ROM. I am pretty new to this area but very excited to learn. Could you provide me the steps and links to the files which I need for this. I appreciate your answers. THanks,
@nicegamer7 There is no known KDZ for the H636 -- you do have a hard bricked device.
@Mike238601 If you have a model that is in the unbrick thread, that has a KDZ available, you can save your device. If there isn't a KDZ available, then you probably have a brick.
Maybe this is useful

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.
Hello,
I have an LG Velvet 5G LM-G900EM and I'd like to swap my OS version from European version to Italian version, but I haven't found any documentation about this operation nor the original firmware image to restore the phone in case something goes wrong during the process.
I'm doing this because I got the phone with android 11 and now in Italy every operator has released android 13, but my phone says (since i bought it) that there is no update available.
So I got suspicious and I decided to dig a bit and try to find out why.
What i immediately noted is that the SW version of my phone indicates V20d-EUR-XX, and the final XX is litterally what it is shown in the phone and to me it seemed a bit wired.
Out of curiosity I searched the original firmware image with mu SW version online, but I couldn't find it anywhere.
So I tried to contact LG support, and they said that my phone is an european version and it does not get updates like the local versions, but they said also that they don't know when the updates will be released for my phone.
In the end I searched a bit more on the internet and wrote in some forums, but no one seems to have an issue like mine.
I hope someone can give me some informations about this and maybe confirm or not if my firmware is indeed a bit wired.
Thanks in advance.
