Can somebody tell me please why updating my unbranded phone branded it? - G4 Q&A, Help & Troubleshooting

I should explain, my LG G4 is a H815P, before the update (when it had lollipop) it was brand free and it didn't showed me the image I'm seeing now (I mean the image that is shown when you turn on the phone after the LG's logo), the change happened when I updated the phone from lollipop 5.0 to mm 6.0. Can you guys explain me please...
I did the update with my sim card inside the phone via LG BRIDGE... btw, the image of the carrier that is shown right after I turn on the phone is the same of my phone line which is Claro, I find this extremely weird because I DIDN'T BOUGHT THE PHONE "FROM THEM" I bought it from another store that sold it as a free carrier (or unbranded) phone.
I don't like the image from that carrier showing up, what can I do without voiding my warranty to keep my phone "clean" as before, like re-installing MM unbranded? and how do I do that...pls help

It's probably just something LG put in there, not that your phone is locked. I used to be from a network called MEO (Portugal) and didn't have any branding, but recently I switched the card for a Vodafone and suddenly LG started suggesting me to install apps from Vodafone (didn't get the boot animation tho) because Vodafone is partner with LG. It's probably the exact same thing you are facing right now, just something LG put on there that is activated when using a card from that carrier

[Q]How do i know if my phone is unbranded[Q]

As above, how do I know?
I bought the phone from TMobile Direct UK, I got it pretty much the day it was released, it shows no signs of Tmobile branding but how can i be certain?
I also have downloaded the zip file of android 2.3 if i update manually will the phone be able to pick up signal despite the OTA not being officially released in the UK yet?
Sorry for the noob questions!
if you try and flash the gingerbread RUU and it works then you are not branded and yes you will still get signal
Do i need root access to achieve this? and what are the chances of making my phone a paper weight?
i was very tempted to do it, yesterday. I booted into recovery and decided i'd wait for more info from HTC who seem to be treating us Uk folk as second class citizens
You don't need root, If you install with the RUU it will either work or it wont, you won't brick your phone, just plug ur phone into ur pc, you need to have htc sync and/or android sdk installed, select htc sync from the pop up message on ur phone and run the RUU
I think i'm too noob and should probly wait for HTC!
you might aswell tbh, gingerbread is being pushed to random phones as we speak, shouldn't be long till everyone gets the ota
yea i know, i'm just concerned that my phone might be branded and i have to wait for tmobile which could be significant wait.
and franky with all the bugs in this version of FroYo it's getting quite irritating.

Actually if you read the threads it seems branded phones are getting the update first.
To answer your original question, when you turn the phone on (from off), do you get a T-mobile screen? The answer is the answer, as a guide.
Nope i don't, i just get a HTC Splash screen.
I tried to insert another sim however (vodafone uk) and it asked me for some sort of 8 digit code.
Could be either SIM lock (the SIM card itself is locked) or the phone is locked to your network (doesn't have to be branded to be network locked).
Check the software number (settings -> about phone -> Software Information) on the phone.
Mine Desire HD with Android 2.2.1 is 1.72.405.3 and doesn't have any T-Mobile splash screen interestingly was primed to connect to t-mobile as there was a little piece of paper which said at the network selection screen choose next despite NO network being selected and T-Mobile not being one of those in the list?
Anyway I believe the 405 bit indicates its an htc (i.e. unbranded) build. The Vodafone uk builds have 161 here instead and my wifes desire that does have a t-mobile splash screen shows software version 2.12.110.4 with android 2.2 installed

[Q] So How does this actually work?

I picked up a pre-owned Gold G3 yesterday, my last one went pop!
This new G3, is Sim Unlocked, but with a Vodafone UK rom (V10a.235.15). After researching and reading around.. the G3 has EFS, so I followed the KDZ back to stock guide and flashed the Open EU rom, which went without any issues and seemed as if it had flashed and replaced the VF Rom, but it still has the VF splash screen, a VF updates Icon (Which can be removed) and software version, yet the G3 still detected and Loaded in my EE UK APN settings and no sign of any VF APN.
http://forum.xda-developers.com/showthread.php?t=2785089
So am I right in thinking.. If I wanted to make this a full UK unbranded phone, so no splash screen with a software V10a.EUR.XX.. I would have to Jailbreak the EFS partition and Replace VFRom stored on the EFS with the EUR-XX rom.
OR am I wrong entirely, so... How does this work
There are so many threads on here, that ask the same questions in different ways, hence why Im a litle confused as how this works
Thanks
Wait Wait Wait
So you cant manually import APN settings right? How about flashing a Rom from another European country?
Dont tamper with the EFS partition under any circumstances. If you do you wont have a IMEI and your phone will be worthless. Carrier branding does not occur within the EFS partition
I remember my carrier apps disappeared from Update Center when i upgraded my Australian firmware to a Taiwan Firmware so im pretty sure it might work for you.
When you flash the KDZ make sure you flash it using CSE Flash Mode

Can I just be clear before I answer... The G3 I bought is Branded to Vodafone UK, I am personally on EE UK and Im trying to remove the Vodafone Branding and make it a factory unlocked unbranded G3.
Thanks for the reply friend. I didnt have to enter any EE APN settings, they were already there, so not sure how that was... because I didnt enter them. Glad to hear its not the EFS, because I would rather use a branded phone and have it working than change its file system and mess it up. Also, I know the guide doesnt state it but I turned ON USB Debugging, would that make a difference
I followed the guide closely so did flash using CSE. Ill now flash another countries KDZ and let you know how i get on?
Could it be that Vodafone UK is the EU Open Rom, just a few minor changes..... What I dont understand is...
The EUR Open Rom flashes perfectly fine, reboots and starts... so why after a perfect flash using CSE, is the Vodafone UK rom still there. Any Ideas.

Im afraid no Luck... I flashed Open France, still booted to VF rom with VF software on it v.10a-235-15), then installed "Italy Orange", which actually worked, booted up a clean LG rom BUT, even though its v.10a, When trying OTA update, it said I was n the latest OS, which is no good, then using LG PC Sync.. it just updated to the UK VF rom again (20h).
So I took a long shot and flashed Open UK, still the same.... boots into VF splash screen and software.. so, Im at a loss. This is why I reckon carriers hide a rom on the EFS partition.
Any thing to add
Thanks

No SIM card inserted after unroot and upgrade

As above really. Not really sure if it's a hardware or a software error here. I've read that the sim card readers can be a little fragile but there was no fuss during the removal so I would be surprised if that was the issue. What I'm wondering is if I've missed something when un-rooting my phone.
I was using a custom ROM, all working fine, but I've got a new phone so I decided to unroot my old one to sell on. I flashed my original firmware using the LG Flash Tool. Firmware file is "UK Vodafone 16G D85510A_00.kdz". It all went great as far as I could tell and I started upgrading. The final upgrade was the install of Marshmallow 6.0.
In order to find out if my phone was locked or not I put my Wife's SIM in. Rather than coming up and asking for an unlock code it simply stated that there was no SIM inserted. I thought that was potentially down to the wrong SIM being in but when I tried mine I was met with the same error.
Have I missed something? Did I need to change the baseband or something during the process?
Any help would be greatly appreciated.
Thanks
I've had kinda same problem since a couple of weeks ago...eventually SIM card gets read for a short while and get back to that No SIM card inserted state.
It has happened with any ROM as well as OG FW flashed through LG tool.
I haven't tried another SIM on my G3 but my SIM does work on other cell phones.

G4 H815 now a H818N after Warrenty Claim, Incorrect Software Version now installed

Hello,
Long story short, I have obtained my phone back from repair in Hong Kong (I am located in Australia). Originally the model of G4 was a H815 using software version H81520D_00_0115 I believe from memory. This phone died because of it overheating causing to do a boot loop/stuck on LG Logo screen.
I ended up getting the phone back from Hong Kong, they replaced the mainboard as I thought and now the model of the phone thinks it is a H818N Dual Sim card LG G4 – Running software version V10c-DS1-HQ, which it clearly is not a dual sim card G4 because there is no additional sim card slot. Anyway, phone seems to be working well except the rear camera does not focus (I have had this issue in the past and I resolved the issue by installing the correct software version, eg 20A, 20C, 20D etc.) Trying to update the phone using software update does not reveal any updates. Using LG Bridge reveals an available update for it, it thinks the software version was 20F or 20H not sure, however when it goes to download it does not get past 0% tested on two PC’s.
I have installed the images I have found for the H818N now which are:
Hong Kong H818N10b.kdz (this one worked the best as it didn’t come up with that error message when you reboot if it’s an incompatible kdz image)
India H818N10d_00.kdz
India H818N 10F.kdz
With no success in fixing the rear camera issue. I have not factory reset though as I don’t think it would have much of an impact.
Have tried to loading: H81520D.kdz image but the LGUP utility (which I have been using for the above process) says KDZ file is invalid, I assume this is because it detects the phone as H818.
Does anyone have any suggestions or locations where I could download more images to try like H818N 10A,B,C etc? Or if there is something I should do cause I have had nothing but issues with these phones
Kind regards

Updated to MM6.0, now when i turn on the phone I see an image from a carrier

I should explain, my LG G4 is a H815P, before the update (when it had lollipop) it didn't have any image from ANY carrier, (I mean the image that is shown when you turn on the phone after the LG's logo), the change happened when I updated the phone from lollipop 5.0 to mm 6.0 and I don't know why!! Can you guys explain me please...
I did the update with my sim card inside the phone via LG BRIDGE...was it the cause of this?, btw, the image of the carrier that is shown right after I turn on the phone is the same of my phone line which is Claro, I find this extremely weird because I DIDN'T BOUGHT THE PHONE "FROM THEM" I bought it from another store that sold it as a free carrier phone...and as I said before, the couple of times I saw it turning on it didn't show the image of this carrier and I've always used the same sim card (before and after the update) I don't even know if this also means that from now on I can only use this phone with this particular carrier...what is going on?
I don't like the image from that carrier showing up, what can I do without voiding my warranty to keep my phone "clean" as before?
