Need help with bypassing bootloader unlock (EE) UK

Gone through the LG dev site, put in IMEI and Device ID, message pops up saying
the page at developer.lge.com says:
Unfortunately, your device (EE,UK) does not support unlocking the bootloader.
Is there a way around this, I would like to root my phone...and this whole "hold" over my android device isn't good at all.
EDIT, Sorry, i've got the LG G4 which is the phone in question, not the LG G3 as stated in my Sig.

I have the UK (EUR) version too from CPW on EE but was able to unlock. What's your software version under About Phone --> Software Info ?
Mine is V10c-EUR-XX

It's official - there are a billion frickin versions of the LG G4 software out there and we don't stand a chance.
Sorry you can't unlock. Check the root thread for that.

Ouch... you serious?? nothing at all.. That's actually s**t.

Surely you'd be able to root using the method in the root thread? I'd hope so as I'm getting this phone on EE in a couple of weeks and was hoping it would be possible

Should be able to root using the method in the root thread with no issues.
As far as getting a G4 on EE, go via CarphoneWarehouse as you get a Euro unlocked device and not an EE branded device.

I've found a few rooting methods... but could someone point me in the right direction to the right thread, please =)

The low effort root method in G4 Original Android Development.
Do not try to absolve me by some quirk of quantum mechanics.

Dam that's a *****. I'm wondering if you could flash the KDZ of the EURO unlocked device and convert it from an EE device to an unlocked one. I know this used to be possible with Samsung device, this is my first LG (apart from a Nexus) so not fully up to speed on these things yet. May be worth investigating though.

Ok found that,
right.... How on earth can I tell what version mine is?
does this low level root actually bypass the "not being able to unlock bootloader" ??
Sorry for all the questions, I have read up...just a bit cautious this time around.... never had this much trouble with rooting a device before.

Yes it doesn't require the Bootloader being unlocked, tbh most questions you have will be answered in that forum, read through the first two posts. All images are there and how to find the right ones.

If your worried about not picking the right version, then I would avoid proceeding with that method. As if it isn't one of the version in the OP, you need to change the commands too. Post a screenshot of your Software Info screen and I'll point you in the right direction.
But you need to read through both those posts before proceeding to understand what your doing.

As far as I can tell, you only have a carrier specific version of software and no actual hardware differences from H815 itself, which makes sense EE just using their own software (like the twats they are). This being the case you should be able to proceed with flashing the H815-10c image and gain root, this may also mean you can unlock the bootloader.
If the worst happens and you can't boot, you can just use a kdz image to revert to stock following the guide here:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
You can gain a stock KDZ with this url, replace 'YOURIMEIHERE' with your imei number:

Well, thank you very much, sir. I really appreciate the help =) Shall try it out now... as for the bootloader...
LG specifically said on the dev site that my bootloader (EE)UK can't be unlocked,
I input my IMEI and Device-ID.. However, I expect you know way more than myself, So.. i'll stay in hope that you, sir..are right =)

can we add root to locked G4? i do not want to unlock bootloader yet h811

is it possible to add root to locked bootloader.. if so can you give me link..
does it work on LP and MM?
what can i do with a locked bootloader?? what options do i have?
thanks.

no no possible ..Root without bl unlock only LP

and if am in MM how do i go back to LP using stock and flash tools?
i think i read some cant go back?? how do i know that am elegible to downgrade?

Yes you can downgrade but I dont know what is the last KDZ to flash in order to root. I had 10F and my phone just came wrong a logic board warranty fix with a 10a from january 10 lol

As far as I undestand yes. You need an specific LP version but Im still trying to find out this. The thing is that every root method is now outdated and my phone came from warranty with a newer version. I just dont know how to proceed.

Ok, according to http://forum.xda-developers.com/g4/general/psa-warning-try-to-downgrade-g4-t3197675 (bottom of first post) you can safely downgrade h811 from 20i to 10n
This whole situation could be clearer tbh

Things to consider:
Windows 10 may not work. I tried for over a day trying to backup my stock system.img using Windows 10 until some guy from another forum told me Windows 10 was probably having incompatibilities with the drivers.
Rooting. I had to make a VirtualBox virtual machine running the last version of Ubuntu (Took me 10 mins in total -downloading-setting the VM) but I also downloaded the files directly to Windows and copied them to Ubuntu. When I was rooting Ubuntu was missing files that were not compatible to copy & paste from Windows to the Ubuntu VM. So download the root_inject files directly to Ubuntu.

Yup that is the low effort root. That one is good when you have a stock room available, in your case V10N.
I went with the Ubuntu one because the version my carrier installed seems to work pretty good so I just needed root and had to do the 3 step rooting method with Ubuntu.
Enjoy!

well i just have root and xposed installed... .
i was told i idnt have balls to unlock bootloader... if he only knew
well i guess you dont know. as you told me i could not root and use xposed without bootloader unlocked.. guess i prove you wrong. as for grow balls dont even go there.. you dont know and once again i can prove you wrong... this isnt directed at you pakito someone else that siad those things.. he said bootloader can be relock and ive never said it couldnt do it.. all i wanted was warrranty. as even new 6xx are getting bootloops...

Whoever said it was not possible to root and xposed with locked bootloader is clearly living in the past. I had Xposed before I sent my phone to warranty, right now Im just trying to figure out why is not installing on my device.

you need unlocked bootloader and only tmobile have it and some european h815. for 6.0
you can root it if on lollipop. but again, you need to know if you can downgrade to lollipop. theres antirollback versions. on mine i cant there V1 V2 V3 am currenly on V3 so i cant roll back to V2. or V1. doing so will hard brick phone.
but you need to search or ask in sprint section, if you can. not all phones has antirollback restricted.. am pretty sure ive seen some beign at 6.o and atirollback is 0.
to chekc what version you are. search your phone hidden menu . enter it on dialer and go to software scroll all the way down and it says antirollback version..

I successfully unlocked my H810 bootloader, but...

Hi all,
my H810 was initially bootloader-locked, so i checked its anti-rollback version in the hidden menu (SVC Menu->Version info->Anti-rollback Version) and i got "non-fusing device".
The phone worked fine, but i hate the word "locked", so i decided to flash a H811 20o kdz with LGUP.
Flashing was successfull, so i converted my H810 to a H811 and i unlocked the bootloader
Now i have TWRP and i can flash custom roms, BUT
...
I live outside US and my device is now a T-Mobile sim-locked H811 :crying: so i can't connect to any mobile network anymore!
Now i can't check my anti-rollback version: if i try in the hidden menu i get a "com.android.phone has stopped" message and i can't see the info i need.
I also tried with the
Code:
*#*#244773825625#*#*
sequence, but with the same result.
So, i have some questions for you experts:
1) there is another way to check if i have still a "non-fusing" device?
2) the anti-rollback version depends on the rom or on the hardware?
3) can i flash a H815 international kdz in order to restore network connectivity?
4) what else can i do?
thanks in advance

1. You've must likely ruined the device by flashing H811 firmware. That is a big no on doing that.
2. Flashing H815 firmware will be the exact same never flash wrong model firmware.
3. Only way to regain network connectivity is if you flash back to H810 firmware that's meant for the device. (Hopefully you didn't loose your efs. If lost it's gone forever turning the device into a wifi only device).
Antirollback is hardware once changed by software.

Yes you can. But it's the only way to make your phone completely working again.
LGUP will/should stop you if it detects antirollback.

Oh my...
That's why I do not share in public my method fully yet. And always saying and explaining about the fuses and anti rollback.. Read my unlock PoC thread..
Yes I'm working on exactly this. You should be able to flash and so convert a device to a h811 and so be able to unlock as you already achieved. But you made a big mistake.
Two tbh.
The first was not to read my PoC thread.
The second flashing a fusing firmware!!!
I believe that autoprime was trying to help but really I heavily test all possibilities and this is not such easy and risk free.
Ok so regarding your current problem.
You're kind of lost and you can flash only firmware with the same anti rollback. But it could be worse.
Head over to my PoC thread and come to IRC.

my H810 was initially bootloader-locked, so i checked its anti-rollback version in the hidden menu (SVC Menu->Version info->Anti-rollback Version) and i got "non-fusing device".
The phone worked fine, but i hate the word "locked", so i decided to flash a H811 20o kdz with LGUP.
Flashing was successfull, so i converted my H810 to a H811 and i unlocked the bootloader
Now i have TWRP and i can flash custom roms, BUT
...
I live outside US and my device is now a T-Mobile sim-locked H811 :crying: so i can't connect to any mobile network anymore!
Now i can't check my anti-rollback version: if i try in the hidden menu i get a "com.android.phone has stopped" message and i can't see the info i need.
I also tried with the
Code:
*#*#244773825625#*#*
sequence, but with the same result.
So, i have some questions for you experts:
1) there is another way to check if i have still a "non-fusing" device?
2) the anti-rollback version depends on the rom or on the hardware?
3) can i flash a H815 international kdz in order to restore network connectivity?
4) what else can i do?
thanks in advance

I'm beginning to think you are either reading and/or comprehension challenged. If you look beyond the title of his thread and read and actually understand what his problems are currently, paying particular attention to steadfasterX's response, he has screwed himself somewhat with what he has done. He has no mobile network connection, he is stuck on his anti-rollback version and limited to what he can do now - that is not a successful unlock or major breakthrough. Rather than posting for posting's sake and trying to achieve Senior member status with little comprehension behind you, suggest you try and learn ....
IF you had actually read and understood anything in steadfasterX's bootloader unlock thread you would know that he has achieved a SUCCESSFUL unlock of an H810.

I only read when its necessary. I read first sentence or two and then normally ignore the rest unless I really have to. I have a busy life and have better things to do than read a forum...

Boss... I read about 50% of USU method thread, understood about 90% of what I read. I'll read the rest when I actually perform it. I was wondering... whats the difference between the fastboot mode in the official unlock vs the USU method? Is it talking about the same thing??

I need some help downgrading/rooting my LG G4.

Hello amigos, just to clarify i'm new to XDA so lets get to it then shall we!
So I bought this LG G4 from a guy on eBay, and it basically just arrived today. So the weird thing about the device is, It has a Anti-Rollback Version 4. Ive personally never seen this especially in the UK. Isn't it just the US that's supposed to be effected by these issues???
Is there any way of getting around this or what ever?
Its on Android 6.0 and its the H815 variant, I've tried booting into the boot-loader and that doesn't work (Yes I've used ADB but that didn't work either I also used recovery which for some reason I can access but not the boot-loader ) This is the main issue. There is also something else that doesn't make any sense. The device has an update from LG, It downloads perfectly fine but when it goes to flash the update it just doesn't flash. It comes up with an error. That's all it says in the recovery, error. Yeah that's about it really. The phone works perfectly fine on 6.0 but I just wanted to see if one of the greight minds here could assist me with this issue or just upfront call me stupid for wasting my money on an old phone :laugh:.

Which H815 variant is it?
EU, USA, TR, Int'l?

It looks to be the EU version to me. I cant be too sure though. Its running on the OPEN EU firmware though. (H81520D)

Yes the model number is LG-H815. It doesn't say if its EU or INT or what ever.
Is this unusual?

H81520D is the software version

you need to unlock the bootloader before accessing it first.
this is the only official way for so.

If I may ask to better assist you, what do you plan on doing exactly?

Firstly I plan on rooting and adding TWRP as I did on my old G3. I tried to use LG's method but it did not allow me to fastboot. When I used ADB it just well, restarted the phone. I used the command adb restart bootloader as it states on the unlocking site. I used administrative permissions. Whats unsual is, I can use adb restart recovery perfectly fine to get to the stock recovery.

The confusing thing for me is, the device has the antirollback version 4
Its the EU version of the H815. It makes no sense!!!!
I'm trying to figure out what could have caused this to happen mainly... The only version with antirollback version 4 is the LS991 ZVF... How is this even been done to this thing!? Its running on the H81520D firmware which 0 of them have the antirollback version 4 that i'm aware of. The bootloader is mysteriously inaccessible by anything I do! This is really bugging me now. Could this be a franken device?

Before proceeding further, check whether your device has SN 404 or other. It is found by removing your battery or checking on the box labels.

To begin with, I rooted mine by downgrading to LP stock rom as rooting MM is not quite easy using this link : https://forum.xda-developers.com/g4/help/how-downgrade-g4-h815-t3264864
Then I had FIsH twrp installed cause I couldn't unlock my BL using : https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048

Secondly, yours has ARB v4. So there are some hardwork involved in finding a kdz that won't brick your G4 on flashing. As you say it is very much confusing. So do proceed ahead only after properly checking your informations and cross examining carefully.

Many people are saying the H81520P KDZ file will work for me, apparently once I install it onto the device downgrading is pretty simple.
As for FIsH, eh... I cant figure it out at all. I was so confused by looking at the page for it, I was like eh...
EDIT: Every time I try to upload the KDZ to the device I get this. https://www.leonf.elhs.co/images/LGUP_05-01-18_11-50AM.png

Installing FIsH is confusing at first...ask me more about it but with proper reading and carefully executing the steps you should be doing great:good:
This common error may be fixed by updating your LGUP DLL file. follow the first steps on https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803

Yes i'm following the instructions to the letter. with LGUP. Still getting the error though.

What happens is, follow the instructions on that LGUP thread that you sent me, I put the kdz in and restart lgup and then its on refurbish. I click start and the antirollback error appears on any KDZ I use apart from the H81520p_00_0314 which kicks out a Flash Fail error. Oh and thanks for helping me with this!
