Unlock Bootloader for H815K - G4 Q&A, Help & Troubleshooting

Hello Everyone, i am wandering how i can unlock the bootloader. I have tried going through the official LG developer way but it says my device is incompatible when i enter my device ID. If it helps i have an Australian H815K model phone.

as long as they say you cant then there is no other way right now we hope they will support more models soon or someone finds a way around to unlock

Custom ROMs on H815 TWN

Hi Guys,
Is there any way to install TWRP/Custom ROMs, on the H815 TWN variant? I tried today to unlock the bootloader today, but it still says not supported (screenshot attached), let me know if any one has found a way to Bump the kernel like on the old G2/G3 models.
Thanks everyone =D
I have exactly the same issue unfortunately. I'd be happy with ROOT for now.
I hope someone in the community can help us out.
EDIT: root (and downgrade from MM if needed) for TWN: http://forum.xda-developers.com/g4/help/twn-root-question-downgrade-root-t3328465
Sorry but it's not possible now. There's lots of us waiting for Bootloader to be unlocked for TWN model H815... but currently impossible.
Luckily we can still have Lollipop with root.

And luckily phones like the Nexus 6P or almost any other competitor allows for bootloader unlocking unlike LG.
So if you get pissed off enough, that's an option

Any way to unlock bootloader for H815 (TWN)

Hey guys,
when trying to unlock the bootloader the official way, I get the error message
"Unfortunately, your device(Taiwan , (TAIWAN) )does not support unlocking the bootloader."
LG support has not responded yet, but the message indicates what their answer will be.
Is there any way to get the bootloader unlocked other than having LG send the unlock code?
I found several threads all over the internet with people describing the same problem, but no solution was posted. Since all those threads are from mid-2015, I was wondering if anyone found a solution by now.
If you find a solution , please let me know .

( "Unfortunately, your device(Taiwan , (TAIWAN) )does not support unlocking the bootloader." )
its clear enough to me... you cant.
and theres no other way.. yet... maybe one day it will.. unofficially.
I asked this a month ago with no luck.
There hasn't been any real progress on having an unofficial bootloader unlock since august/september of 2015.....
It's almost a year since anyone has really talked about it. I don't think it's ever gonna happen :/

I asked the LG developer support. All they replied so far was that by company policy, they do not allow models other than "European market" to be unlocked at the moment.
I answered that I am not satisfied with this "policy" and that I'd like a reason for them to block customers from their freedom of choice what to do with their devices. No answer yet - will post here when I get one.

More people need to ask their developer support program to make an official unlock for the bootloder...this is not a one man job we all need to participate in this all those having TAIWAN H815 models..
Is there any way to at least gain root access on these phones? Mine is running software version "V20c-TWN-XX", which is Android 6.0 with security patch level 2016-01-01.

LP yes. but i seen 2 different post claiming root on MM with locked bootloader.
It's easiest to just downgrade to Lollipop via LGUP. Though it still took me a while to find the right pre-rooted image to flash on my phone.
I just completed the process of using LGUP to rollback to Lollipop v10c, and then rooted it. Surprisingly I was even able to get Xposed framework installed with the bootloader locked. I guess the only thing I'm really missing is TWRP, but I can live without it.
Thanks for pointing me in the right direction!

not so sure ... but LG has removed the team the worked on past phones and eithe has a new team or will be not making any more phones. .... g5 sales arent too good...
I've the H815 V20d-TWN-XX 6.0 MM with sec. patch level 2016-06-01, and as I've read, no way to unlock bootloader for this model, so frustrating.
I was hoping at least to find a way to have this particular G4 version rooted with the bootloader locked, does anyone know how can this be done?
Been looking for a solution but haven't found anything so far, I'd just flash a previous version but some people wrote in other threads that this 20d has noticeable battery improvements...
So any help with, as for now, the best way to go to get root access in this device, is very much appreciated. I've been trying to do this for weeks
Thanks!
I am assuming with the boot loader locked, there is no way to try out any of the custom ROMs here ....what a shame as I wanted to give lineage a go

Motorola XT1609 (Verizon) Unlock bootloader?

Hello Xda Developers,
I was hoping if someone could answer this question as im not that big in flashing / bootloaders.
I was thinking is it possible if someone does unlock the XT1609 (Verizon) Bootloader. That you can flash the XT1607 (OEM) Bands to the Verizon device? Would that be possible? Any help would be greatly appreciated. I have a project on this device so I need to get as many answers I can get. Thanks!
-Diofi Innovation
As far as I know, at this point in time there isn't a way to unlock the Verizon xt1609. I have the same phone and dilemma. However, my question is, will they come out with one soon?

the way things usual work out you should be able to flash over the modem files to any rom. So long as theres no physical difference it ahould work to flash different bands over, at least when using a custom rom.
but we still.need to wait for someone, anyone, our lord and savior, to get us past the bootloader.
any one have solution to unlock bootloder for xt1609 Verizon waiting fro the replay seniors

I think there are some little differences. Perhaps, there are no PURE GSM RF module, filters, etcetera in XT1609.
Yeah we have unlocked the Moto G as well Verizon but that doesn't do anything to the device. It only gets 4G not Cellular. Unlock Codes are easy to get from the manufacture. But you need to reformat the whole device to make it work like the OEM Moto G.
And how can we unlock it???

[VS996] Verizon V30 Bootloader Unlock/Root Progress

Hello. Just would like to get the ball rolling on this, as no one has yet to make a thread for this device. I realize chances look slim right now of any possibility, but we might as well get to brainstorming.
hope in some Root user method ....
unnecessary thread. please see below for all updates for all models. At the moment we are speculating that only ONE model will be available for unlock in the USA. The unbranded unlocked carrier model US998.

That isn't the point of the other thread the other thread is for tmobile v30 which already has a bootloader unlock just no fastboot flash commands
The first post states its for the T-Mobile model, but all the information up until now is the same as we currently have no progress. It just so happens there are more T-Mobile users of the V30 than there are of the Verizon model. Once unlock, fastboot, etc can be addressed for one unlockable model any progress will branch off onto other US unlockable models.

Not really they face different challenges and why hold back the tmo thread for issues pertaining to unlocking a bootloader when they don't need that part?

Agreed. There's also a general bootloader unlock/root thread that even supersedes the T-Mobile thread.
LG V30 - Unlock bootloader and Root
https://forum.xda-developers.com/lg-v30/help/unlock-bootloader-root-t3665927
It was started back in September, and the T-Mobile thread was a fork of that one. Because the T-Mobile people already had bootloader unlock and didn't want to discuss bootloader unlock. So they started their own thread, and that thread op says he ONLY wants to discuss the T-Mobile variant in that thread.

I'm making this thread to update the progress towards root and such for the T-MOBILE LG v30

Well, Verizon LG V30 variant doesn't have bootloader unlock. It's quite different from the T-mobile situation. So, this Verizon thread is another fork.
ALSO, due to information not available back in September I wouldn't be surprised if some or all the bootloader locked carrier variants (like Verizon especially) have fastboot flash commands -- if someone could unlock the bootloader.
This is a complete turnaround from what I thought back in September, when it seemed LG had removed the fastboot flash commands from all the 2017 flagship phones. If you read that post I linked above I give my reasons why the change in thinking.
I still believe the LG Developer Bootloader Unlock list is the only GUARANTEED way these LG V30 phones can be rooted -- and thus why I advised everyone to buy the phones that would be eligible for that bootloader unlock list... But I would be very curious to see an AT&T or Verizon or even U.S. Cellular LG V30 model bootloader unlocked by some exploint -- to see what's underneath.
While this could all be discussed in the LG Bootloader Unlock and Root thread, there's nothing wrong with having a dedicated Verizon variant thread if there's enough interest. Basically you will need some developer to find an exploit.
Read post #2 of the T-Mobile thread. At first it seemed like it was starting out as duplicate/rehash of the LG V30 Bootloader Unlock and Root thread -- and I pointed out it was unnecessary -- until the op said he only wanted to discuss the T-Mobile variant. OK, then.
Same here.

I'm considering getting a V30. If I find a US998, is unlock & root virtually guaranteed? Also, it sounds like the T-mobile models are unlockable & rootable. If I find a carrier-unlocked T-mobile phone, will it be able to use Verizon's LTE technology (or whatever is the latest) or will I be stuck with GSM or something else that doesn't match the best Verizon has to offer?
Thanks!

The open market US998 V30/V30+ has not yet been placed on the LG Developer Bootloader Unlock list. Should be, soon (it's been six weeks since release).
The T-Mobile variant does not yet have root. One guy said he has it figured out, but he bricked his phone and is waiting for replacement. In the meantime, other methods are being worked on.
You wouldn't have Verizon CDMA bands with T-Mobile phone.

Most likely not, they use the iemi to identify devices.

Okay so, since I'm sticking with the VS996 (for now) I'm really optimistic on root/bootloader unlock, just to clarify though, so the current situation is that the T-Mobile variant HAS unlocked bootloader BUT commands disabled hence no TWRP or root...
On the other hand we have the Verizon variant which has LOCKED bootloader, but could potentially have all commands intact/not striped away...
So all in all, if some amazing devs find a way to unlock the bootloader, we could potentially have a strong chance of root?, (Assuming commands are actually there)
With android 8.0 officially rolled out, I'm just wondering if anyone is currently looking for any exploits/or working towards cracking/unlocking the bootloader, thanks for any replies, staying optimistic :fingers-crossed:

Personally not a developer or really know anything about developing root, but we could start a bounty for the VS996 and/or other versions.

Sounds good, hopefully this will add some encouragement to any developers currently trying :highfive:
Omg, spent hours scouring XDA for 'VS996' & even just '996' only ever finding one thread... and a random Google search finds this thread. Anyways, my adhd makes busy forums hard to sift thru and I'll cut to the chase as I've been reading for hours... On this VS996...
I have a VS996 that can be used for fodder (testing).
I hate Verizon and want on Google Fi so I'm kicking myself for not getting a Pixel at this point. You got stuff you want me to try? Sweet. I run Linux as a competent user.... But im currently in the middle of soldering a new power jack on my laptop... while ALSO in the middle of moving....
Lemme know.

Unfortunately, although I'm sure everyone in here is very appreciative of this, I don't think there's any developers actually working on the VS996, I hope there is/or will be for you guys, but don't get your hopes up...
You can't even get to the hidden menus with the Verizon variant.
Just so everyone is aware. The VS996 by Verizon does have root with unlocked bootloader. You can Frankenstein Flash vs998 firmware to 7.0 then update to vs998 8.0 then flash an exploit unlock.bin found in the 'WTF...' thread.
I successfully flashed my VS996 to 998, updated to Oreo then flashed the exploit unlock.bin and can confirm this method works.
Verizon can suck it again. Woot.

[question] how can i rebrand my honor 7x to international version ?

Hey There Guys,
Can anyone please guide me how can I rebrand my Honor 7x (BND-L31) to international variant....
Please Help as I haven't got a single update on BND-L31...
Rebranding is not recommended. Lots of things can go wrong in the process. I say you should flash a ROM, it will always have the latest updates.
I recommend OpenKirin's ROMs, especially LOS.

I surely understand the dangers of rebranding as I've done it before to my P8 Lite but I want updated EMUI on my phone and the variant I own [BND-L31C185D002] didn't even got EMUI 8....
I'm in a similar situation. I just got a BND-AL10 that I'm trying to turn into something I can use in the US. Can't get a bootloader unlock code apparently, I missed it by like 3 days. Am I the proud owner of a $200 brick?

This hwota-bnd has rebranding process in it. Don't remember which oeminfo files are included. Take a look. If other oeminfo files are needed perhaps we can get them.
**Edit
Just looked again, the eominfo file for c185 is not there
https://forum.xda-developers.com/showpost.php?p=77134788&postcount=6
But maybe before rebrand, try to install the c185D001 version

I'm also in the same boat. Bought a BND-AL10 from India and not even the 3G or 2G bands of Tmobile is working here in US. I contacted Hawaii several times asking for the unlock code but they don't bother even to listen (for obvious reasons). I managed to unlock the boot loader by paying $5 in dc-unlocker. (google and you will find it but I'm not authorized to post the link here). Now I have the unlocked bootloader but I'm still searching for a solid answer if I can flash another ROM (such as the US version of 7X, Mate SE) on my device without bricking it. Please let me know if you have any update.
