Error when trying to unlock bootloader. Anyone who can help?

Hey guys. Following. Yesterday I tried to finally unlock the bootloader on my h815 and I was really excited and given it is the EU Model I actually expected it to work just fine. But it didn't. And now I am more than confused. The error I get using the LG Website is "Device ID is unmatched. Please check your Device ID. Your account will be locked if you enter the wrong Device ID more than x time(s)." I checked the Device ID a thousand times. Wrote it by hand and copied n pasted it from the console - no difference. Checked the IMEI too. But the one under the battery matches the one on the box matches the one I get with the IMEI Code you type into the dialer. Also checked the country code but well it is CZE which should be just fine. Any suggestions/solutions to my problem?
Cheers,
a very confused and annoyed Lisa

In that case you should e-mail LG and ask them directly so that you won't screw anything up. Since everything is alright I have no idea what's the problem and your best bet is with them

Alright thanks

Need help to find the proper firmware to flash

Hi all,
Sorry if this is a noob question but I am completely new to LG. I have a second hand LG G4 h815v10h on android 5.1, and I want to upgrade manually since the OTA doesn't find any update for me.
I installed LG UP but after installing the phone drivers and launching LG UP, it shows me "model unknown" and I can't run the software because "You have to select a known model, please"
Here are my phone specs :
Model number : LG-h815
Android version : 5.1
Baseband : MPSS.BO.2.5.c3.00100.M8992FAAAANAZM-1
Kernel : 3.10.49
Build number: LMY47D-XT
Sofware version : H81510h
Thank you so much for the help !

You could check out this link: http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/Marshmallow+6.0/
However, as the phone is 2nd hand, the ONLY way to be sure what actual model you have bought, is to open up the phone and check the model # on the motherboard. There are guides with pictures on the web to show how to do this: https://www.ifixit.com/Teardown/LG+G4+Teardown/42705
You could end up bricking your phone flashing an incorrect kdz for your actual phone model, so better to be 100% sure, first.

Thanks for the answer.
After looking for the model number, I found out mine is F500L, even though I have h815 installed
Also, LG Bridge managed to find an update : F500l30B but fails to install the update everytime.
Aaaand another problem is even though I want to flash the phone with adb, I can't unlock the bootloader because the box "Allow OEM unlock" in development options doesn't want to activate itself. Grrrr...
Any other clue ?

You could try using LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to flash using the upgrade mode but it might be better to use the refurbish mode with the same android version you are on now and if successful, then use the upgrade mode to install the newer android version.
However, it looks like whomever you bought the phone from might have converted to H815 following this guide:
Lg G4 F500L - Fixing and Converting to International H815 Model at https://forum.xda-developers.com/g4/general/lg-g4-f500l-restore-signal-flash-815-t3214574
I would type in "go back to F500L" in the search thread box there first, to see what other members have had the same issue and whether they were able to do it successfully etc.

LG G4 H815 running MM with Anti-rollback version 4 !!!!!!!

Helle everyone, I recently purchased an LG G4 H815 running MM from eBay, it is supposed to be INTERNATIONAL VERSION, but I had noticed first that Android PAY does not work (when I try to launch the app it does not let me in and says that I am running a custom ROM or I have a rooted phone or unlocked bootloader) which none I personally did. Then I tried to verify my anti-rollback version because I couldn't update to Nougat, the HIDDEN MENU code supposed to work for my model H815 didn't work, but instead, the code related to the American versions (ATT and T-Mo) WORKED, AND MY DEVICE HAS anti-rollback version = 4 !!!! as far as I know, the most recent one is 3, how is that even possible??? (see Pictures for more infos)
( Unfortunately I couldn't figure out a way to upload pictures here so here is a link to Imgur)

Thanks for any further help or infos.

There are many Frankenstein devices out there.. One thing is 100%: you have a refurbished device. So it's definitively NOT a pure h815.
H815 devices have no ARB!
Please make a backup of your device with SALT ( https://bit.do/SALTatXDA ) - basic is fine. And share the resulting files i.e. via Google drive.
Having that backup is crucial important regardless. And I want to take a look into your bootloader stack to find out which one is installed.

Thanks for the reply man, i really appreciate it.
1/ Yes it is a refurbished device
2/ I think it is Sprint version LS991 (according to the ABR - Sprint is the only version that has version 4)
3/ I checked the IMEI online and it confirms that it is a SPRINT device
3/ I found online that there is some CUSTOM ROMs that "converts" literally any version to H815 (mine shows 4g LTE logo when I am using ONLY 3G WCDMA in settings)
How to retreive the bootloader stack info in order to share it here for you to take a look ?
I am now trying to install SALT in LINUX - I will keep you up-to-date

Making a backup with SALT will also get the bootloader stack. Just share the files afterwards.

Pls paste the SALT debug log in advanced menu as well. It's enough directly when started SALT with the device connected.
Many thx
Nvm got it. The important stuff is in your screenshot.
You have a converted device. Meaning you have the ls991 bootloader stack plus the h815 system. This is possible but more interesting would be: is your SIM working? Do you get mobile Internet? 3g,4g?

Many thanks for reply, yes everything works fine (Android Pay does not work), DATA works fine BUT even using ONLY GSM/3G WCDMA (no LTE) in the settings, I always see the 4g LTE logo when using DATA, I think they somehow changed/ replaced the 3g data logo in the status bar with 4g LTE logo, in order to make the user believe the device is compatible with his LTE carrier frequency (which is not correct of course)
This SPRINT device does not support LTE in the country I am using it in (Czech Republic), I verified it with the help of willlmyphonework.com website.
This is really so disgusting and unfaithful behaviour from SOME Chinese sellers on eBay, the SPRINT version is the cheapest one, so in order to RIP off customers, they CONVERT these models to H815 in order to sell them for more, and not everyone would have the knowledge to dig deep into the device info in order to verify the legitimacy of their product specs, this is sad...
Anyway, what should I do now which this devise? how can I at least install Nougat or have the OFFICIAL firmware without breaking the device??
Thanks for your time and precious information

Well.. We don't know if it is a ls991 or a h815 or a complete other device. The only way to say this for sure is to open the device and looking on the mainboard(!). But regardless you have a fusing device now and so you cannot install a h815 bootloader stack anymore. Say thx to ARB ( https://bit.do/antirollg4 ) which can hard brick your device.
It SEEMS that you can boot h815 ROMs but if you try to replace the bootloader stack coming with the N zip or the TOT (which you can find here on XDA) it will hard brick.
Interesting is that h815 is able to boot. It MAY be possible to boot N by just replacing modem, system and boot partition though. That depends on your bootloader stack.
Try to boot into fastboot from android:
adb reboot bootloader
You should see the fastboot screen. Could you make a photo of that? We MAY have luck and its a special one.

Unfortunately this command adb reboot bootloader just reboots the phone normally to android ( normal reboot)
I couldnt boot into fastboot because the Send command returns FAIL when I type id (so i cant move on in the process ...) Maybe locked bootloader??

Too bad. Try that :
Power off phone
Press vol down and keep it pressed
While doing so plugin the USB cable and wait
You may see fastboot now.

No luck, the phone starts to charge while turned off and connected to the computer, there is something really strange going on here, it is like this mode had been blocked or something....

Well no. Some firmwares do not allow to boot into fastboot that's not that unlikely.
So what I can say is that you have a ls991 bootloader stack with a h815 system so it MAY be possible to install nougat but not yet. I will integrate flashing partitions to SALT soon. Until then you have to wait.

read the SALT thread. I provide changelogs for every release.
flashing is possible even now in a beta state. waiting on IRC (read the SALT thread - OP) is the only way if you want to participate on the beta test.

Hello! I have similar situation I have H815 ... but LGUP says H81521y it seems it has some strange software/modem/rom uploaded. It is marshmallow 6.0 I cannot get into fastboot mode so I cannot unlock bootloader. I tried to install TOT of Nougat via LGUP but no luck cause it turned out I have antirollback V3.
Is it possible for me to install TWRP and then any custom ROM? I don't know what to do right now...

It seems it's H815 with AT&T Software with anti rollback v3. Adb reboot bootloader just restarts the phone, I tried to enter bootloader by keys combination. It enters firmware update mode.
I think due to v3 rollback I cannot do anything with this phone, am I right?

Correct (axcording to my experience). I had the same issue with my previous phone. It turned out to be a ls991 with H815 software.
The only way to know your Hardware is to take a look inside the phone , you will find it printed on the motherboard.

Mine has H815 printed on antenna and few other parts, in system it also says H815 in LGUP its H81521Y I think it's H815 with AT&T bootloader and therefore they flashed anti rollback V3 so at this point I cannot do anything...

Latest Software for -G710ULM?

Hello, I just bought a G710ULM off the bay and verified the model before purchase. I received it and the software verifies it's a G710ULM but a IMEI check shows it's a PM (Sprint). So the software is still on V10b with no updates coming. I'm thinking this is because the update checks the IMEI and sees it as a Sprint device even though the software says G710ULM. I see a version on LG's site for 11e, is that the latest version? Trying to figure out if I'd been duped. The seller is a MAJOR seller and I'm thinking they are getting these as new Sprint units and LG or someone is reflashing them. I might be all wrong but 2 different IMEI checkers say it's a Sprint.

G710ULM owner here on Project Fi, the latest version is M10g. Updated to it about a week ago. Your phone may just need some time, or you can try using the LG Bridge software on a computer to update the phone over USB. Otherwise, it may just be a carrier thing.

I tried Bridge but when I check for update it gives an error. Wondering, when you check you IMEI does it show up as a G710ULM ? thank you

I got the same problem, got it on ebay, In settings the model is G710ULM, but the real model is G710PM. I also try updating via LGBRIDGE i aslo get the same error. Trying to get a KDZ file but i just cant find one and i don't know if putting another region firmware would work. There's a youtuber that had sprint LG G6 and just changed the Firmware (used one from canada, it work and also UNLOCKED all bands for world wide use).

Same ebay phone Same issue here with no s/n showing hardware is fine unlocked running tmobile usa.. Signal seems bad. Never see 4glte icon only 4g , H, G. Hopefully we can flash to some other firmware to get lastest update.Right now running v10b-Lao-COM firmware i guess thats sprint rom

I did flash mine, had the ULM software with SECURITY PATCH MAY.... What i did is download ULM 10g file from website, used LG-UP to flash it, But first you have to create a DLL file for LG-UP for this to work, if not you going to a error on LG-UP when you hit START.

Yes, the G710ULM firmware 10g that's the project FI(I used another link, not the same you posted, but it should work). I was running the same firmware V10b-LAO-COM, The project FI, was the only one I could find (ULM), so that's why I decided to use that one and because I read on Google that those phones are unlocked. I don't have the steps, but I could make a post in a few hours. And also it's still unlocked, using it outside the US. (I got this one on eBay unlocked version, but it's Sprint).

Does it work with Sprint now? I have the same story - bought "unlocked" g7 on eBay, shows G710ULM in settings but IMEI shows as Sprint phone.. Was working on Tmobile but when I activated with Sprint it doesn't read the SIM.

Well I think it really depends on you, maybe you should return de device, if Sprint doesn't work.... On eBay it said "UNLOCKED". So if it does not work just return it... I am using the phone outside the US.

Apologies for replying to an old thread, but I have one of these modded sprint g7 that shows G710ULM.
Could someone be able to be kind enough to list out the steps used to manually upgrade the stock android 8 up to android 9 please?

Can't update to Android 9.0

I just bought samsung s9 SM-G960U but can't it won't update to android 9.0 manually ! it says processing failed
I did some researches I found that it's carrier-related . Some solutions suggests that I use odin to update but I can't choose the right firmware !
In fact :
- when I try to check the csc using *#1234# it show g960usqu2are6 ( I think it's Verizon using google)
- when I log on into samsung website and enter my imei . The product info shows that my carrier type is Sprint
- when I check "about phone/service Provider SW " on my phone the first line contains TMB after G960U and the third line is TGY/TGY/TGY
I'm confused but I want to update my s9 to android 9.0 . Help me

get the firmware here
https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U/VZW/download/G960USQU4CSC7/265795/
get the most recent version of Odin (i didnt source you a link for that)
open Odin on your computer
unzip the package and get your phone into download mode, connecting it to your computer. Allow drivers to install and when Odin recognizes your device by showing a random number in the port field. Then place the files in their corresponding spots in Odin paying attention to which CSC file you use as one factory resets the phone and the other simply applies the update. It is recommended to use the factory reset CSC when changing from different iterations of the Android OS. Press the start button, allow it to full run the firmware push. It will then automagically reboot (yes, automagically), and youre done.

Once a phone is unlocked, it stays that way forever. Firmware has nothing to do with a phone's locked or unlock status.

Depends how it was unlocked, seen a few members flash new firmware and the phone is SIM locked again, these unlock companies must use some modification to the firmware rather than unlocking it properly

Good to know. Wasn't aware that a phone could be unlocked with firmware alone. I guess it's a temporary overlay or something that "fakes" being unlocked?

Yea must be something that emulates the unlock somehow but once reset or flashed it's gone, always seems to be people who have bought the phone second hand unlocked, it has worked fine with their sim until they reset or flash different firmware, then it's locked again

No network on device after firmware update

sorry, i should have worded that differently. I didnt need the IMEI, just the fact that the IMEI is what came up and that a valid IMEI shows

i havent tried this method, but i did stumble across this
Boot your Samsung Galaxy S9 or Galaxy S9 Plus
Activate then access the USB debugging mode
Sync your Samsung Galaxy S9 or Galaxy S9 Plus to your desktop PC
Download this: EFS Restorer Express
Access the application and then open the EFS-BACK.BAT file
Choose a method in order to recover the EFS via Odin
