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.

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...

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?

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

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

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...

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!

How can I solve this problem? (A520F)

Hello! I upload a capture of all the errors. I'm very interested in solving the IMEI. Thanks for your help!

On stock firmware does it show a correct IMEI?
If so, the problem is random flashing.
Do you have backup of the .cert and or .efs files?
If so, search on how to use them.
If you know the IMEI and it is network blacklisted, use a service for unlocking it. Online you can find it.
I hope I helped.

I don't know if it helps, but when I flashed a Combination for my phone, when i had an unknown IMEI, it showed me one working and network working too but I don't know if you can make use of that IMEI or even if it is valid.
And solved my unknown IMEI just by flashing last stock rom.
If you have your phone rooted, you can extract those files via adb, plenty of tutorials online.

Hm what is left is just to flash stock, keep it in a wifi connection 168 hours and then flash twrp for rooting the phone and getting those files, lets hope they are not corrupted.
The waiting it is because samsung have seven days as the time.for the bootloader to be unlocked and allowing the phone to be modified.
Good luck.

Convert/Upgrade the AT&T G6 to H873 OR US997 With VoLTE

Lets get those warnings out of the way! Warning Do this at your OWN RISK! There is NO WAY BACK to AT&T firmware at the moment and might never be. Only loss is you'll loose VoLTE and WiFi calling (If using the H873 Firmware)
Idea came from this thread which also perfectly works on the AT&T model! https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966 Its the same method.
We finally get Network Selection AND being able to Disable LTE as well for those who like it, and removing the carrier branding in the top corner. (See screenshots)

Curiously the thread you've mentioned in the OP (https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966), claims to be able unlock the SPRINT variety only by merely flashing it with an "open network" type firmware.
In my experience, I've never seen any phone, ever get unlocked by merely flashing a firmware (even if it's "open network" type).
Usually the network lock information is stored in a non-volatile security zone, so this just doesn't make much sense.
Now, I'm not doubting the OP, it's just extremely unusual, but it could be an anomaly or firmware bug.

Well this thread is not for unlocking the GSM model which it CANNOT. It’s meant for having a generic open firmware removing all the AT&T junk. Meaning if it’s not unlocked it won’t be unlocked after flashing.
Now the Sprint model is CDMA which is completely different than how GSM works. Sprint CDMA phones are usually software locked to keep it from being used on GSM networks. That explains that

Getting moisture in charging port and another popup that asks if I want to keep it as a charging device for another phone. I'm sure it's a minor bug and a restart fixes it but I'll be trying to update tomorrow. Saw on a Korean site that there's newer options.
No regrets by the way. So nice finally having a modern os

Works perfectly, thank you very much!
But one thing: I had to start LGUP.exe with admin rights. If not it was not possible to choose the kdz file.
Btw...is there a way to remove Facebook, Instagram and the hole sh*t? For sure i choose remove LG apps as well but these apps still there.

Not without root

Got ya! Well now it makes sense... first, the description "unlocked" is a bit misleading, a more accurate description would be "un-branded" firmware. Second, on the Sprint side I can see how the open-firmware could "unlock" the network, course that would disable the CDMA side, only GSM would work.

Yes, here's how to disable any app WITHOUT root.
First, save the app list into a file with this command issued from your ADB folder:
adb shell pm list packages -f >c:\Apps.txt
Look through the saved file (c:\Apps.txt) with any file viewer/editor (like Notepad etc.), search and find the app's name you wish to disable.
For example, the Facebook app:
package:/system/app/Facebook/Facebook.apk=com.facebook.katana
Copy and paste "com.facebook.katana" (without quotes) into this command line:
adb shell pm uninstall -k --user 0 com.facebook.katana
The above will disable the Facebook app till you factory reset or update your phone's firmware.
Just repeat the command for all other apps you wish to disable.
Enjoy!

The H873 kdz works which was the point of this post.
There is no H871 flashable firmware out yet and quite possibly won’t be.

It wouldn’t have anything to do with the firmware unless 1. The LCD is for a different model or 2. Your phone is not a H871

Downgrade to emui 5

I got a Huawei mate se and didn't realize that allowing it to update to Android o would block the bootloader unlock tool. Is there anyway to downgrade my firmware so I can unlock my bootloader?

There is a roll-back ROM on firmware finder. As long as it shows your IMEI as approoved, it should install.
That's the nice clean way.
There is a dirty ( possibly dangerous way ) by using the nougat service ROM. That ROM is for bnd-L21, so not sure how an unlocked bootloader will handle it. It has worked on unlocked before.

I have been attempting to use firmware finder but I can't wrap my head around actually pushing the update. I heard you need an outdated version of hisuite but no one specifies what version. Any help is appreciated =)

Insttall firmware finder from playstore.
In the app select the "hamburger" menu, from top left corner. Select instructions. Either watch videos, or read the text guides

The mobile app as far as I can tell doesn't work on newer versions of android. They even have a disclaimer mentioning that the app only works for older devices now.

You are not on 8.1, the app can work.
But I was only referencing the app for the guides linked inside.
You should be able to use it to flash b330. Which should work in DC

My bad I am on 8.0 to be specific bnd-l34 8.0.0.341(c567) and as much as I've tried I can not get it to work on the phone following along on the videos. They are using the app on emui 5.0 not 8.0. It doesn't work anymore on 8.0

All there videos revolve around emui 5.0 or lower. It stopped working with 8.0

Because the locked bootloader, you can only use the firmwares that are approoved.
Chances are , the only one that's approoved is the b330
And if not , then only option is the service-rom. Followed by dc-unlock, then the hwota and correct ROM
It has been done.
There should be confirmation back in the mate thread somewhere.

I'm searching. I know i have recommended this process many times, and got many success responses. But I am striking out in finding threads with confirmed responses.
This search only shows 4 found matches for the search info. One does fit real good, but the author has made it sound , not real credible.

This post you made here sounds doable.
This service rom so far has been only thing we found that will load with three button method (dload)
But it is not a full rom to keep on device. It needs you to follow up with flashing fullOTA of your correct version after.
https://www.androidfilehost.com/?fid...83647474828964
1. Unzip download
2. copy the dload folder to root of sdcard
3. power on phone holding all three buttons
4. After phone finishes and reboots, unlock frp and bootloader, if needed
5. Use Huru or HWOTA to flash correct firmware for your model/ region.
Enlighten me what is huru or hwota? If I were to flash this does it boot up into android or is it non functional?

Yes, this should leave you able to boot. And with build level that should allow DC unlocked to give you the code.
Remember like I said before this is kind of a dirty way around and 'could' have issues unknown. Like what if DC does not give you a code, you would then be stuck . (Though you are stuck now)
Huru and hwota are very similar. They both use TWRP to give custom flashing control.
Hwota uses modified stock recovery to flash full ota files.
Huru repacks full ota files so that TWRP can flash them.
Since doth start with TWRP , bootloader unlock is needed.

Just spent most of the morning going back and forth with someone else with mate see, and they just did restored his device with the service ROM.
I do not now what he was restoring from, but he ended up with "unknown model" and default build number of 8.0.0.46
This is because of (probably) some data corrupt issue making the flash go bad. But he was able to run the ROM and unlock boooader.
Difference is he already had his unlock code.

Have you seen this guide?
It is for "official" hisuite roll-back
I have not rolled back so do not know it it works though.(I checked with my device, it shows no downgrade available)
I know the roll-back firmwarm listed on firmware finder was listed as "bond" and not "bnd". So this means not available "officially"
