[H815] What is my current bootloader version? - G4 Q&A, Help & Troubleshooting

Dear XDA Members,
I just got my new LG G4 H815 and wanted to unlock bootloader and root immediately. I have not actually checked avability before because I got it for a good price and was not caring about this. But I still wanted to know if it is possible to unlock the bootloader unofficially? The official way is a bit too risky for me because I would lose software warranty and nearly every defect could be given to software if LG wants to.
At the moment the only way of unlocking it is if my bootloader was on v0 am I right? Maybe someone can tell me my version as I am to stupid for this and do not want to risk anything.
PS: As I am not able to post links please tell me which entrys from the hidden menu you need and I will copy them for you
Kind Regards,
Mössi

theres atm no unofficial bl unlock.
and why u need bl version.
v0 or v1 is only important by downgrade (if u on v1 u cant go back to earlier firmware with v0 -> if u try, bricked...)
u can unlock everytime! (if lg developer page support unlocking for your device)

Infos for possible G4 buyer

Hi,
i'm from italy and i'm interested in G4 european model H815.
I read a lot in the forum, but i really have some doubts yet. Hope someone can clarify them.
- First, is touchscreen problem really and definitively fixed? In which fw version it was fixed? What is latest european fw version?
- Is it safe unlock bootloader? We could have warranty problem doing it?
- It would be my first LG device, so maybe this is a newbie question, but what "kdz" and "tot" stands for?
- Aside touchscreen problem (fixed?) and led problem (fixed?), which other problems i could expect with this device?
- Finally, is there already a custom rom that is better (in performance, fixes etc.) than orginal's one?
Thanks for anyone help me to understand.
I'd actually like the answer to these questions as well, being a Samsung fanboy, this is my first LG device.
I never have any problem with touchscreen.
There's official bootloader unlock directly from LG for h815 but it will void your warranty.
kdz and tot refer to factory image
Volume over earphone is pretty low. Can be remedied with viper4android.
I'd just get root with low effort root method and xposed running. There's rumor that unofficial bootloader unlock is possible only with original firmware (which will be lost once u receive ota and can't be restored).
Unofficial bootloader unlock is still a rumor
hi, i have the H815 European model too, also my wife
We never have any problem with the Touchscreen
From what i have read, if you unlock the BL via LG any Hardware defect is full covered by the warranty
but i think they can refuse a soft-bricked phone if they would (but i know LG as really cooperative for such problems)
you mean kdz - this is the LG Format for fimware releases, tot also but not oficially LG i think
i never needed or used tot files.
We have no problems with this phone here. this means not that there is no problem
There are custom rom's (and one or two kernel's) but Stock is faster for now (android M)
the 7 HD Rom is a stock based custom Rom wgich performs really good and delivers
a all in one soloution for the most people i think.
fire3k
Thanks for answers, all clear.
But about touch problem i understand you didin't have it, but i would know if people having it have the problem now really fixed. Or it was only placebo effect for the last updates...

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

Which model G4 should I buy for rooting/TWRP/Roms/Xposed

Looking to buy a new phone, settled on the G4, gonna make sure I get a revision 1.1 and a 603 serial phone.
I am gonna be on MetroPCS so let's keep that in mind.
Really need help chosing, I am looking at the 815 and the 811 along with US991.
Any help would be great.
Or if you had a phone suggestion below $350 that would be comparable or better please share.

So you would suggest the 815 then.
the h815 from the specific countries on that list are the only ones with unlockable bootloaders. if you buy an h815 from a region not on that list you cannot unlock it and thus cant have twrp, custom roms, etc
The H815 or international version is the best choice ...LG is giving u the files to unlock ur bootloader ...theres are many roms out there u can flash and try ....And I m talking from personal experience i have a H815 and i have already flash 3 different roms and i have unlock my bootloader and didnt encounter any problems at all ....A friend of mine bought another h815 and encounter a bootloop after a official software update but after a factory reset all was working good ....i live in europe ....

id say go with h811... if you unlock bootloader you warranty is over... if you buy international if something happens you must send back phone for repair...to what ever country you get it from according to the list that can be unlocked... not sure if you buy in the states the h815 comes with no warranty. either..

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.

Read the OP carefully and be fully aware of the risks and limitations. steadfasterX is working hard to overcome the locked bootloader situation and has had some success to-date using his own version of Lineage with testers.

you need to go into hidden menu. and go to software and look at antirollback.. am no t also sure but seems a 0 means you can if it has a number like V1 V2 V3 if you in V3 and lollipop is in V1 wich ithink it is. cant.
