sprint lg v30 can i flash other carrier roms - LG V30 Questions & Answers

When i had my galaxy s7 on sprint i was able to flash other carrier roms and unlocked version roms through samsung flash tool .Can this be done with lg phones on some kind of flash tool ? Sorry for question just was wondering i use to flash unlocked version on my sprint v30 to have a bloat free phone

So the question I have is this. If you are going to root and unlock the phone anyway, why not just remove the bloatware on the phone? Why concern yourself with other carriers?
If all the carriers are equal as far as communication frequencies are concerned, then unlocking the phone is all you really need. Once unlocked (you don't even need to root for this) you can go to any carrier.

I could do that without root. And flashing unlocked version rom has no carrier bloat. Also i said nothing about rooting

If memory serves and may not, so unless something has changed, flashing any function on an android phone requires root access.

"Unlock" has different meanings in a dev forum. You mean carrier unlocked, SIM card unlocked. Not bootloader unlock.
U.S. Cellular has SIM card unlocked, carrier unlocked version. The "open market" version which will be released in early December will be both carrier unlocked and will be eligible for official bootloader unlock.
You basically want to convert your phone to another phone? Yes, with Samsung phones you can do something like that with Odin. I have a friend who bought UK Galaxy S8 and flashed Australian ROM (with Samsung Pay) through Odin. He's not rooted and doesn't want root.
There is an LG flash tool, to flash KDZ and TOT firmware:
http://www.droidviews.com/download-lg-flash-tool-to-flash-kdz-and-tot-firmwares/
I know with the V20 H910, once Dirty Santa was patched in order for someone to root their phone, they had to basically flash their phone to an older Freedom ROM, which was not yet patched, then install some engineering mode module, and then run Dirty Santa.
https://forum.xda-developers.com/showthread.php?t=3664500
So, some of what you're are asking can be done. But that ROM flashing was temporary and on some carriers you would lose signal. It was just a step to getting the bootloader unlocked and TWRP installed. Then the regular H910 ROM was reinstalled, and all signal functionally restored.

NOTE: this is a very simplified answer to the question. There are even "patched" versions of the tools to allow you to flash versions you aren't supposed to.

No, after the V20 LG has now added signature checks so you can't flash other variants to convert to another.
This was not widely known a few months ago. We thought that V20 trick would still work.
Too bad.

Just bootloader unlock won't help for the carrier branded models. Here's why... the T-mobile LG G6 already has bootloader unlock, but LG removed all the other ADB flash commands. So, bootloader unlock is useless on the T-mobile LG G6. Six months later, still no root, no TWRP custom recovery. It's like having the keys to a new car but the car has been melted down to block of metal. The keys are useless.
"BOOTLOADER UNLOCKED" T-MOBILE LG G6

All the fastboot commands have been removed on this device other than lock and unlock. Until there is a method to flash a custom recovery we can't really do anything.

Some more information on the T-mobile LG G6 from an expert:
autoprime said:
T-mobile H872 G6 doesn't have root yet and will only have root once they have a method to get TWRP onto the device. Fastboot boot/flash commands are disabled so it will take an exploit of some sort to get TWRP flashed to the recovery partition.
The only other G6 device that will have root is whatever device LG adds to the official bootloader unlock list which can be found here: http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryId=CTULRS0703
The models added to the bootloader unlock list will be the models to get for proper bootloader unlock, TWRP and root without jumping through hoops like the Tmobile H872 variant does. (currently U.S. and European unlocked carrier LG G6)
For all the other G6 variants without bootloader unlock (AT&T, Verizon, us cellular, canadian, australian, south american, korean, chinese, etc..), a new root method of some sort would be needed but there is nothing public yet. Once a public root arrives and if a debug bootloader image is leaked (like the LG V20) then other G6 variants might be able to have an unlocked bootloader allowing TWRP and permanent root.
Just laying out all the current info to this date. I have no plans to work on any of this as I do not have the device.

Even if you could unlock the bootloader to the other carrier-branded models, LG has probably removed the ADB flash commands from those phones as well? Only the official carrier unlocked versions are eligible for REAL bootloader unlock, the way you are thinking about.
Look down in the development section here for the official carrier unlocked LG G6 (which is eligible for REAL bootloader unlock with ADB flash commands present). TWO pages of ROMs, kernels, custom recovery.
Yet, over on the "bootloader unlocked" T-mobile LG G6 forum, there's 23 pages of root begging thread, which has now been abandoned as a lost cause.
Not only would you have to get bootloader unlock from LG, they would have to add back the ADB flash commands -- or a dev find some exploit to get TWRP custom recovery installed. And that's not been possible yet on the T-mobile LG G6, even though it's bootloader unlocked!
If you are interested in dev stuff for your phone, sell your LG G6, and get one of the official carrier unlocked models -- either the LG G6 or even the new LG V30.

For the carrier-branded models, yeah probably no hope.
My point is LG will say if you are interested in REAL bootloader unlock, they already provide that for the official carrier unlocked models.
Removing the ADB flash commands on the carrier-branded models was very devious "security" method so that cracking the bootloader on carrier models with an exploit (like Dirty Santa) still wouldn't do any good.
With the T-mobile LG G6, devs have has six months to try to find some method of installing TWRP on that unlocked bootloader and not been successful. They may do it some day, but when? Meanwhile the carrier unlocked models have bootloader unlock AND ADB flash commands. If you were a dev, do you go through the already open door or try to break through the brick wall?
Decided to sell my G6 and switch to Samsung after this twitter reply from lg.. this will be last lg phone i bought until they let us unlock bootloader or anyone unofficially unlock..

Why? They said that they don't make the policy of what to unlock.
LG provides two phones that are unlocked and you can develop on.
Most carriers do not want you to have a rooted phone.
Samsung has KNOX which is even worse. If you try to root the phone you can trip KNOX and brick the device.
Samsung does not unlock devices unless you buy a, wait for it, developer version.
HTC is fairly easy if you find someone to S-OFF the device. But that's not HTC.
Mototola will not unlock the bl on branded phones. On other phones it's hit or miss.
LG with their carrier unbranded phones and Google seem to be the most supportive.
If you buy a Pixel from Verizon, the BL is locked and you can't unlock it.

Glad you found a solutions.
IT varies from country to country and sometimes I forget that.
Here in North America (US and Canadian carriers) getting a Samsung unlocked phone just isn't normally possible.
You can't get a version that supports North American LTE with a boot loader you can unlock.
LG and HTC along with Google phones that are unbranded usually can be unlocked here.
Never buying or getting an lg phone ever again...not even for free. Biggest mistake I have ever made...

check the t-mobile threads. there's already someone trying to do just that
Can we start a petition to at least unlock the boot loader for Non carrier branded G6 versions ?
I am losing more and more confidence in LG on supporting our device after their concentration on V series and branding change for G series.
We definitely need software support to our phone to justify all the initial hypes and the money we spent.
Please clear my mind, if someone is officially unlock the bootloader for LG G6 (H870 or US997), then the phone will just lost the warranty. So LG will deny the device.
Than why the other types has not got the possibility to unlock.
If they do so, then we (customers) will have just one way - not to buy phones from them in the future.
Hello,
I just started the petition "LG Electronics: Unlock boot loader for all variants of unlocked LG G6 Smartphone" and wanted to see if you could help by adding your name.
My goal is to reach 100 signatures and I need more support. You can read more and sign the petition here:

Same pinch.
I am coming from LG Google Nexus 5x and I am already suffered a lot for coming out of Nexus line.
I assumed that we can at least Install custom firmware and can be in the bleeding edge.
But LG has prevented that as well.
I would also never buy an LG Phone again.

You need the right file sent by LG because content of the file depends by your IMEI and Device ID. Each unlock.bin file is unique.

Same here. I don't do much dev work or CFW now, but I hate that it's not even possible with this variant. I owned a Google Nexus 6P that started having battery drain issues at just over a year. Nexus Protect will send you another phone for $75, but since they refuse to acknowledge that the battery issue exists, if it starts having issues, they expected me to pay $75 to get another defective one. No thanks.
This phone can't be unlocked, but I suppose I'm just thankful that it doesn't drop to 20% battery in 2 hours and then shut off 10 mins later!

Probably a stupid question... but.

I bought a LG V30+ (V300) Korean version and I was wondering if it would be possible to flash an international stock rom on it.
Is this possible?
Anybody experience doing so?
Thank you.

There is no chance to fladh anotoher Rom in ours Lg V300k yet. First will be needed to unlock our bootloader (not achieved yet), then TWRP and finally to have suitable ROM's for ours devices.

On LG V20 they flashed another ROM (KDZ) using a custom made LGUP.exe file -- BEFORE the bootloader was unlocked. They did it in order to unlock the bootloader, installed TWRP, then flashed back the orginal ROM while keeping TWRP.
https://forum.xda-developers.com/showpost.php?p=74689131&postcount=123
However that method would only help you (on South Korean variant) if you then had a way to unlock the bootloader AFTER you flashed it.
This "flashing another KDZ variant"method would possibly work on the T-mobile H932 which already has easily unlocked bootloader, but just has most of the ADB flash commands removed. It would temporarily turn the H932 into an LG US998U once that KDZ is available. Install TWRP, flash back to original H932 firmware, while not overwriting the new TWRP recovery.
But doing that on South Korea model won't let you unlock bootloader because your IMEI is ineligible on the LG Developer website, and the bootloader unlock exploit the V20 devs used has been patched.

Shouldn't that be possible on this? Or was there a patched exploit after that? Sounds similar to the G4 if I remember correctly.

The bootloader unlock exploit they used on the V20 has been patched, but the T-mobile H932 V30 doesn't need a bootloader unlock exploit -- bootloader is easily unlocked. What it needs is a US998U KDZ and a custom made LGUP.exe to allow installing KDZ from another variant. That custom LGUP.exe is what does the magic, but a dev needs to make one that works on the LG V30. Go follow the links I posted.

Questions before purchase

I am contemplating buying a used LGV30 H931 AT&T phone for use on Cricket to replace my Huawei Honor 8. What does flashing to the unlocked firmware get me other than sim unlocking the phone? Does it get rid of the AT&T bloat? (99% sure it will.) Will it continue to get updates? Will they be the AT&T updates or the unlocked updates? (My guess is if it does they should be the unlocked variants updates.) If just cross-flash without rooting, will it pass safetynet?
Thanks for your answers. I have had multiple devices I have rooted and ROMed but I have had little success flashing another variants firmware on my Honor 8. Not sure if it is worth the hassle or if I should just leave the stock AT&T firmware on the phone.
Im pretty sure you have answered the questions in your research. flashing unlocked firmware allows you to unlock the bootloader. my gut says safetynet wont be a worry for cross-flash. US998 updates. no bloat but there is still the LG bloat and I remember in the past reading up that non-carrier phones auto downloads the carrier's bloat. I dont personally stay unrooted.
The biggest benefit is getting the carrier logo out of the notification bar - lol

Question Unlocked vs T-Mobile version questions.

I currently have both the T-Mobile version and I purchased an unlocked version from BestBuy.
https://www.bestbuy.com/site/oneplus-nord-n200-5g-blue-quantum-64gb-unlocked-blue-quantum/6468089.p?skuId=6468089
Are there physical differences to these two phones or are they just running different software?
EDIT I looks like its not possible to unlock the bootloader of the T-Mobile version just yet and I have been doing some searching and it looks like the unlocked version is closer to being unlocked. If anyone can confirm a way to bootloader unlock either I would appreciate it.
My end goal here is to get access to Unlocked/Uncapped tethering without having to use a 3rdparty app or companion app. The ability to flash custom ROMs and root access. But also the ability to flash back to a 100% stock rom.
Any help or advice is greatly appreciated.
EDIT I see now you can get the bootloader unlocked on both version by sending a token to Oneplus and waiting 7 days.

The only physical difference is that the T-Mobile version has the IMEI engraved onto the back of the phone while the unlocked variant does not and the original boxes are slightly different.
Both phones run different software. It is possible to flash the unlocked ROM to the T-Mobile version of the phone after unlocking the bootloader, but that breaks OTA.

OK, this process has been hell, but I'm gonna try and consolidate everything I've worked out so far in one place. This all applies only to the T-Mobile variant (ie. it comes preloaded with all the T-Mobile bloatware) of the N200 on the T-Mobile...

I'm trying to do the same thing with the N200 for a hostpot @xVoidx . I'm curious if you succeeded, and what ROM did you end up using to do it?

Question flashing us firmware over tracfone one

Hi
Is it posiible to flash us international firmware in locked tracfone moto g play phone.If yes can this unlock the phone to accept others sim cards.
thank you
yahiadal
If you can unlock the OEM bootloader you should be able to install the RETUS stock rom image. You're more likely to have issues when flashing other phone carrier rom versions (or channels), and if the image you're installing has an older security patch than what's currently installed.
