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 :/

Of course I meant an unofficial way when I wrote "other than having LG send the unlock code". Anyone working on that?

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

There may be an unofficial way.

Can't get bootloader unlock code

Hi, so I'm trying to get a bootloader unlock code for my 7X, but when I enter my info in the online registration form (https://emui.huawei.com/en/unlock_detail) all I get is the following message and no code: "If you have any questions about the unlock code application, please contact us."
Of course, I tried contacting customer support, as well as the official Huawei/Honor service center in my country, but all the people I spoke with were rude, uninformed, and refused to provide me with a code, even though I sent them Huawei's official statement on the discontinuation of the bootloader unlock program. It says all devices that launched prior to May 24th are eligible for a code, but I was basically told "Naaah, Huawei told us not to give out codes."
Further complicating the matters, my Honor 7X was purchased from China, even though it's the BND-L21 EU version. I really want to get my hands on a code before the program is discontinued. Any help is appreciated, thanks!

Are you sure it's a L21? China should be AL10 maybe you can flash back to AL10 and see if any changes to the codes.

Yep, pretty sure. Bought it off Aliexpress, but it's the European version (or at least that's what it says in settings - BND-L21). I even recently updated to Oreo via Huawei Firmware Finder. Don't know what's going on...

Maybe the seller reflashed the ROM before sending it to you?

Hi,
I'm facing exactly same problem.
In the settings, shows BND-L21, but the sticker on the back of the phone shows BND-TL10 ! @Yanachkov, did you found a solution?
Thanks in advance.

Maybe try contact by email? https://consumer.huawei.com/en/contact-us/?tag=email

I've sent two emails, two weeks and 3 days ago, respectivelly, but no response at all...
I'm worried because huawei will stop the unlock code application service by 2018-7-24, and I would not like to be stuck at EMUI forever...

I did it yesterday with no problem through this website: https://www.emui.com/en/plugin.php?id=unlock&mod=detail

I've got BND-L24 3GB/32GB

Almost with no hope and contradicting all my expectations, today I've received the official update notification! Even with the BND-TL10 device running BND-21 ROM.
Running Oreo now.

I contacted Huawei and requested a bootloader unlock code. Unfortunately they are no longer providing this information to customers. There are a couple of threads stating you can retrieve an unlock code from DC-Unlocker for roughly $4 but I haven't tried this method yet. Currently on EMUI 8.0 & Android 8.0 with BND-L24. looking for anyone who has successfully unlocked their bootloader using this method.

Bootloader status on Chinese device

Im waiting for my device to be shipped. The vendor sells a Chinese Whyred then installs global rom with play store. Does that mean the bootloader has already been unlocked? Can i use my Mi account with privileges to unlock it straight away or have to wait the 15 days?

Why didn't you just get a Global Version?
See here: About locking a Global Rom on a Chinese device. <<<< New Xiaomi procedure.

It says "China version global rom" quite a big seller on AliExpress. So I assume that's what they do. I don't mind, I was just wondering about the bootloader with all this. I wanted the 6gb machine which they didn't have in the international version

Yes it hard to get 64gb Global version as not many resellers stock it.

Are you not worried about the lack of Band 20 for LTE use there!
Your device will probably be fine in cities, but out in the country you won't get it.
Having Global rom, won't unlock more bands because it is hardware dependent.

Lol I know this. I'm not really bothered. I have global Redmi note 4 with band 20 but 4G still weak with my provider. I rarely use data and with oreo I tend to keep it on GSM/WCDMA to save battery
Edit. Well I've read around and about, apparently relocking the bootloader on Chinese device will definitely result in soft brick (which is music to my ears as I want it unlocked) except the guy via aliexpress chat said after flashing Global rom they relock the bootloader ><

Some partner has an account with permission to open bootloader? it has been reset and I have to wait 360 again

Rebrand from HMA-AL00 to HMA-L29?

Hi all
I'm trying to rebrand a Chinese Huawei Mate 20 (HMA-AL00) to the international version but I'm new to rebranding concept. What is exactly? Is it just installing a new firmware or does it have more implications?
I've found this from funkyhuawei where they cleary state that it is not possible for this model. However someone on Mate 20X says he did, in fact is trying to go back to AL00.
Can someone help me to understand how does this works? Will rebranding change IMEIs as well?

You cannot do this unless you have a bootloader unlock code. That's the first step.

From what I've heard, Kirin 980 makes imposible to do this. Please correct me if I'm wrong since I'm giving up and buying a Mi 9.
PD. I'm selling a Huawei Mate 20 Chinese version. Used for a month ?
