So I was wondering if this is possible. My phone (running lollipop 5.1.1) is locked to a carrier but I was planing on flashing an unbranded 6.0.1 (from Italy). Marshmallow will eventually come to my country but I just can`t wait anymore. Will flashing this firmware brick anything ?? I am well aware that the phone will remain locked to my carrier, but is anything else going to be affected ? Anyone had a similar experience ? Your answers are really appreciated.:highfive:
Depends on the phone. Generally, if it is locked to a carrier then other firmwares will fail when trying to flash due to other differences such as the modem/baseband. There are exceptions, but pretty sure they are few and far between.

Thanks for your answer. It's galaxy a5 2016. Better not to touch anything. Don't want to mess is up within just 2 months after the purchase.

Hi all,
I have seen a good offer for a branded G5 from an European carrier and I was wondering if there is any known way yet to de-brand it, in order to free it from the bloatware that I suppose it will be packed with.
If not, do you think normally this would be possible within some months from release, or were there already cases in the pase where this wasn't possible ever?
Thank you very much.

Accepted... I wrote a bit careless and I can see how the request was kinda funny.
Let me reformulate... In case I find the branding too disturbing and I want to flash a stock unbranded image (which I believe is possible for European H850 even if branded by carrier, right??) then I will miss OTA and maybe won't even be able to sideload OTAs like I used to with Nexus 5?

If you remove the original firmware flashing a different one you will lose OTA, but it seems that on G4 is possibile to receive update through LG Bridge (but i'm not sure), obviously the update you will receive will always been related to your brand.
Sideload as far as i know is not possibile on LG devices, because the Stock Recovery is made for Hard Reset only.
For now it's not possible to flash firmware on the G5, but some users are working both on LGUp and Flashtool 2.0.1.6 Here

OK thanks!
I would not see the point of providing a way to unlock the bootloader from LG itself even, if then you don't give people the possibility to flash something else on it, or maybe I'm missing the point of unlocking bootloader.
(talking about Italian Vodafone or Tim btw)

With the official bootloader unlock you lose the warranty, and there is no way to recover it, by flashing a no-brand firmware on al lg device the warranty remain (exception made for us carriers maybe).
Note that with an unlocked bootloader you can flash many things (roms, kernel, mods, xposed ecc...), with LGUp or Flashtool you can only flash official lg firmware.
So, LG provides an official bootloader unlock so the users can use their smartphone's full potential, but doesn't allow to flash official firmware because there is the smartphone update center for otas, and LG Bridge fo recovering and flash the whole firmware update, and not only the ota.
It's been forever since I've been here, missed this place. I am practically a noob now.
Here is my scenario:
I have a Verizon-branded S9+ / SM-G965U on the firmware/baseband G965USQ3BRK2. It is paid off, assured it is carrier unlocked and has also never been modified, pure stock. I'm looking to switch carriers from Verizon to another service. It's also my understanding that Verizon phones are a pain in the hiney and there may be issues with data, features, and other nags and warnings because a non-Verizon SIM is in use. Had an S5 that worked on other carriers but was a nightmare to configure.
Will I be condemned to a similar nightmare of nags and warnings, or will it rebrand it's self and allow me to receive OTA updates on the new carrier? Just not sure of what my options are, the search results yields conflicting information where some had to flash some firmware and others didn't.
Any recommendations would be appreciated.
I converted an unlocked Verizon S9+ to an unbranded, unlocked device, using it on T-Mobile and couldn't be happier with it. You have the option of flashing your own carrier's firmware or the factory unlocked, and it will improve your situation, no more SIM card notifications and all that.
P.S. I was in the same situation as you, used to be on here all the time but felt like a noob all over again. But a super helpful member here guided me through the process and it was completely painless, one quick flash with Odin and it was all good.

Welcome. Looks like there's some instructions here: https://forum.xda-developers.com/ga...icial-stock-firmware-thread-samsung-t3764479. However you will want to make sure you find the patched version of Odin to get past the fact that you are flashing a different firmware than is currently on the phone. And you will want to flash G965U or U1 firmware, that also has a 3 as the fifth number from the end, just as the firmware that's already on your phone.

Thanks for your help and for answering the questions.
Is there any benefit to flash U1 or would just U work?
Would the firmware downloaded using SamFirm work with that version of ODIN you linked?
Do I have to go through a rooting process and install TWRP prior to going ODIN on my phone? Or can I just go into download mode on my device, click yeah about a custom OS, then do the ODIN bit?

The U firmwares are those from carriers and the U1 is from the factory unlocked unbranded variant. so it's up to you if you want your carriers own firmware or just a generic Samsung version. If you need Wi-Fi calling and or volte, there might be a better chance of it working with your carriers firmware but the unlocked firmware does a good job with that as well, I have both of those features working perfectly with the U1 firmware and a T-Mobile SIM. Just make sure to use the CSC as opposed to HOME_CSC, so that your phone is fully wiped and configured for your sim card. I will say one advantage of the unlocked U1 firmware is free built-in caller ID ?
No rooting necessary, in fact it's not even possible on the US models, so just boot into Odin and flash the firmware using the patched version of Odin.
Hello!
I need to fix this issue it's ****ing annoying to be honest. So I have an ATT S9+ and after the Pie update my phone NEVER HAS FULL SIGNAL! I've even went as far as standing under the cell tower and nothing. I was on the CS7 and updated to the CS8 via Odin and the problem PERSISTS! When I was on Oreo I didn't have this issue, this problem started right after I upgraded to Pie.
I'm want to Downgrade or switch this one to TMB but I'm afraid of tripping knox or locking the phone to TMB. (It's code unlocked).
I really want to fix this issue. It's very annoying.
I know your frustrated but the answer won't change if you make a new thread asking the same thing as your old one...
Also standing under the cell tower won't give you realistic results. While capable of sending/recieving signals in a wide area they are not aimed at (or pointing) downwards at the tower base.
Flashing from G965U firmware to G965U1 firmware will not trip knox at all because your flashing official firmware files. I myself have gone from Sprint firmware to the unlocked firmware (G965U1) and to Tmobile firmware without any knox issues.
As for downgrading this is where your out of luck unfortunately. Downgrading is not possible because of the bootloader version your using. Specifically CSC8 uses bootloader version 4 and the last oreo release uses bootloader version 3.
You can only flash firmware that has a bootloader version that is the same (or higher) then what is installed on your phone.
TBH I would contact your cellular provider and ask them to look into the issue. Maybe they can do something to help resolve your issue.

Hey! Thank you for the info! I tried with another sim card from another carrier but the issue remained. I'm going to try to flash everything again with another version of odin and uncheck the auto-reboot option so that I can factory reset from the recovery after its done.

By any chance, do you know where I can find the stock ATT files? I can't find the anywhere.

Sorry unfortunately I do not. I haven't been able to find them myself when I used my S9+ on AT&T before switching to T-Mobile...
When I was with AT&T I had just used the G965U1 firmware since I would not have gotten access to any VoLTE and etc that required an AT&T whitelisted IMEI (to be provisioned for the features) and my phone wasn't an AT&T branded phone (since it was originally from Sprint).
I'm looking for the latest USA factory unlocked firmware for the Stylo 4 (KDZ file), does anyone know where I can find that? I have looked everywhere I can think of and everyone has carrier specific firmware, but not the one I am looking for.
The specific model is LMQ710ULM.AUSABK.
The IMEI is: 357183090498307

It is the unlocked model sold directly by LG in the USA, so it is non-carrier firmware.

Hi there,
You can try this website.
https://lg-firmwares.com/
or
https://lg-firmwares.com/lg-lmq710ulm-firmwares/#tab=firmwares
since your phone is network unlocked I think it might be safe to reinstall the firmware.
However, if you have your doubts feel free to search it online or ask LG directly.

Thank you. I found out that they never released the KDZ for the factory unlocked phones (region USA). So, the only way to update my phone would be to flash carrier firmware, which, is kinda risky, since it would technically be a crossflash. I would likely lose certain features, such as Wi-Fi calling and/or VoLTE. One of the few firmwares that supports wi-fi calling is the T-Mobile firmware, but I wouldn't flash that firmware because it is different than the hardware of my phone (their model has 2 GB of RAM, mine has 3 GB of RAM, etc...

Hi there,
Yes, while I was researching it online I found two firmware for this phone for the US region. But anyways have you tried using a PC suite from LG to reinstall the firmware. Or have you tried going on to the recovery mode and just reset the whole device. Or better try to install a custom ROM, to be honest I think it might be okay if you flashed a Europe region firmware, but make sure you back up the current firmware. I flashed a Samsung phone which was used to be locked and then I unlocked it after that I flashed the carrier firmware and it didnt carrier locked my phone. But anyways try your best.

Hi. I want to flash a Brazilian firmware (dual SIM) into my US hardware (single SIM). Both are Snapdragon. Reason is that I want to use the Brazilian Samsung Pay. Bough the phone in the US but I live in Brazil.
Can I flash THIS ROM without problems? Will it trigger Knox? Any loss in functionality?
Thank you all.

not possible. also, is there not a CSC for your area you can flash instead?
I don't know why these guys say it's not possible, maybe it isn't with your model. I also don't want to give you any bad ideas or anything, so use your own discretion & research.
My phone was unusable when I did this, so I had nothing to lose when I did this (It worked though).
I easily flashed my canadian note 8 with a us firmware using modified odin (must be same version bootloader).
It has warranty status 0x0 (aka, Knox is NOT tripped).
AGAIN, I'm not advising you try this with your model, unless you know what you're doing. I just want to make the information available to you.
Edit: I'm just waiting for someone to upload snapdragon beta 3 one ui 2.0. I'm going to try the same method to convert my Canadian s9+ to USA version.
Edit 2: I can confirm this method works on my Canadian s9+ aswell.

Yeah I don't think it'll work on mine, since it's a single sim phone, and the ROM I wanted was for a dual sim version. Unless of course the hardware is the same and the second SIM slot is present. I could try, but I don't want to risk it. Maybe later when Sammy stops updating the phone.

Unfortunately not. The SM-G965U1 is the US unlocked version. There are only CSCs for American carriers.

if its truly unlocked, then you should already have the U1 firmware on it. Get modded Odin and the U1 firmware, flash it in Odin and go from there. I never looked back after ditching the carrier junk on my phone
Sometime ago I did somethinh like that on my Arabian S7 Edge that I bough in Paraguai, it was Dual Sim model and i flashed ZTO CSC via Odin, and the phone was working well, but i'm not sure if the reverse works, and even the models were similar (F vs FD version) in your case u have 965U vs 9650, I would not take that risk, i thing that a korean or chinese model is 9650 too
look at this picture, US version has more bands so the modem could be different, you can try but you're risking your phone

yep, they are different phones that just so happen to use the same processor. Different bootloader, same chassis for whatever reason. Anyways, there have been threads talking about converting the 9650 to a 965u, but ive never seen anyone confirming that it indeed works. Big risk, but as long as one can get back to Odin mode, one should be good.
