I've bought a used G4 from someone who is "pretty sure" (but not 100% certain) that it's a European model, as it was purchased from a seller on Amazon shortly before the phone was released in the UK.
I want to root the phone, so my question is: if I try to unlock the bootloader using the official LG method, but the phone turns out NOT to be a European model, am I likely to brick the phone?
No, if it cannot be unlocked, lg simply won't give you the unlock.bin file for your phone. So just try to get this file from lg and see...
Thanks. I just tried requesting an LG unlock code and it seems I'm out of luck as I seem to have a Taiwan model :0(
I guess there's no sign of a bootloader unlock for Taiwan H815's yet?
Am kind of frustrated ? i need to unlock the bootloader and i can't, that's the reason i bought lg h815 eu and it cannot unlock bootloader please someone help
hi, so I was trying to unlock the bootloader before attempting to use an AOSP pie rom using this guide on the official LG site http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Anyway when I come to step 9, I type "adb reboot bootloader" and the phone reboots in fastboot mode. Then when I type "fastboot oem device-id" the phone freezes and I have to press the power button to restart it, meanwhile in the powershell command page it says
Code:
C:\Users\chahi\AppData\Local\Android\Sdk\platform-tools>fastboot oem device-id
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed
I checked my drivers and everything seems to work perfectly fine. I am at my fifth attempt and I'm beginning to feel pretty desperate. If anyone encountered the same problem or could help me solve this I will be very thankful !
Thanks in advance.
NB : I'm on windows 10 and my phone is running the korean pie rom.

I cannot 100% say what the cause is with certainty (I have the Sprint version and I absolutely hate this piece of trash) but others have reported similar issues from actually having a different variant that was cross-flashed to the EM model and sold as EM when it's really a Sprint version (for example). What happens when you enter your IMEI number in LG site, does it return the EM variant or something else? That's where I would start (unless you have already done this and confirmed it's EM). Non EM versions lack the full ADB support so we can't unlock the bootloader. This is the same point I lockup as well but mine was not intended to be unlocked.

Thank you for the quick response !
Yes I actually typed my IMEI in the LG site and it gave me a gray OK so I guess I truly have the EM version ? (knowing that only the EM is supported idk) Are there other methods to make sure I have the EM version for sure ? Also worth noting that I bought the phone new from North Africa so it must be the european version and not a carrier one.
Thank you !

Not that I'm aware of but if the LGdev site let you get the unlock code then I will assume it's real as they do validate it. Normally I would suggest to reach out to LG but that's a waste, they won't help. In fact they shutdown the dev recently because of unlock requests so they don't care about us so that won't help you. I'll do some research and see if there's any official way to help but hopefully others will chime in with the answers.

That's what I actually did, I sent them an email but I'm still without any response. Thank you for your help tho ! Is there any unofficial way to unlock the bootloader on the LG G7 that I'm unaware of ?

Good luck with LG, they most likely will do nothing to assist you. That's my biggest gripe with LG, they suck with customer care nor give 2 craps about us, the customers. My LGG7 sucks so bad, it's barely usable but they will not do anything to help me nor Sprint so I'm leaving both once my horrible lease is up. All I can say is to sign the bootloader petition and leave LG, it's the only way they will ever change and even then, they probably won't. They will soon be out of business just like Blackberry's downfall and for the same reasons. They don't listen to the customers and change, nor did RIM with activesync, now RIM is a mere fraction of what they used to be, LG mobile is next. I hear so many complaints about LG devices, not just LG mobile but the entire company. All the same type of complaints across all LG products, no customer support when the device stops working and they pass the buck every time, and locked bootloaders (for LG mobile).
There is no unofficial unlock yet, that's why I'm so unhappy with the piece of junk! If I could unlock and install my own flavor of AOSP then it would be an entirely different story and I would fix my own issues and have an awesome device. Instead the jackalope in charge of LG decided to keep the bootloaders locked with no support to unlock (except for EM) but even that barely works (your issue).
I don't know what else to say except LG SUCKS, LG is terrible. I so wish I hadn't let the Sprint rep bully me into this horrific device. I should have stood my ground and not accepted the deal which came with this expensive paperweight (LGG7).

SIM unlocked, yes, bootloader unlocked, no (on Sprint and everything other than the European model, no, EM model, yes), the rest of us, no, huge difference. I would pay a small fortune if bootloader unlocks were possible and why I bought the LG octoplus, still no option yet unfortunately.

Are you 100% sure this is not SIM unlocked using a modified octoplus (I have already gone down this path) so I bought my own octoplus. I am pretty sure all these "unlock" are merely SIM unlocks and not bootloader unlocks. I've investigated this pretty deep and it was only SIM unlocks not bootloader. As far as I'm aware, there is no hacks or mods to unlock the bootloaders for any LG G7 as of yet. eBay results are all SIM (which is simply using oct to apply the US-unkocked m ok model unlocking the SIM).
If you can find a REAL bootloader unlock method that works and unlocks my bootloader, I will PayPal you 20-30 bucks (I'm not joking). There is no method yet that anyone I know, knows of.

It's not sim unlock
It works by installing g710em bootloader and then flashing an unlock.bin .It's actual bootloader unlock. You can probably even do it yourself on a octopus box but I'm not sure what does it allow and not allow you to do.

If does exist, I can't find it on eBay or the internet, only SIM unlocks. I will keep checking but I don't see anything to unlock the G7 bootloaders.

Hey Piatch, i'm stuck on your same situation!
I have a new LMG710EM taken a month ago in a store, today with the Pie release (I'm in Italy) I found some time to unlock the bootloader, root, debrand (my G7 is TIM branded) and update to Pie.
I'm not new with LG, I come from G2, G5, G6 and now G7, never a problem (apart from the slowness in the updates I like them).
Well, just your situation, only the wording is a bit different, to me it says FAILED (Write to device failed (Too many links)) then the phone reboots and freezes in G7 logo and I have to press the power button to restart it, like yours.
I've tried everything, even reading online, different USB cables, different fastboot versions, but nothing worked.
Then I unbranded via lgup refurbish option to have a clean install and reinstalled all, thinking that maybe the new OS would solve but nothing, same message.
Can anyone help us?
It is the first time in several years that I have not found a solution.
Thank you in advance

Hi f0ster, I did not find any solution because I was lacking the time and tbh the skill to do it. I think we can't unlock the bootloader while under Pie ? Maybe if we roll back to Oreo, then we can unlock it and then update to Pie again ? I don't have the skills nor the confidence to safely flash Oreo on the G7 (I had bad experiences with bootlooping on the G3 and G4). Maybe you could try this way and see if it works out for you ?
Hello Wise men and women. I recently bought an LG-G7 ThinQ secondhand for what I thought was an excellent price. When I got it home and looked at the phone details I noticed why. The phone is rooted, bootloader unlocked of course, with Magisk and no custon recovery, operating on 8.0.0 firmware. I knew all of this when I bought the phone and had no issue with it figuring I would just upgrade and take it from there. The model says LM-G710 according to 3cs, 6.1 screen, G7 Boot image, so I am confident it is a G7. Under Hardware info and when attempting to use LGUP or LG MSTool however, it is seen as LM-V35OULM. In Terminal the phone is seen as Judyln, but just about everywhere else judyln_lao. The firmware is currently V35_11g, and I would really like to upgrade it to 10 when all is said and done but right now I have reached the clueless stage. Any ideas on how to go about fixing this problem?
On a side note the IMEI, MEID and ESN all read goose eggs. I was able to get service to the phone and even register it with LG (unbelievably) so at this moment I really don't care unless of course that would keep me from upgrading. Not sure if its pertanent but it seems odd to me.
Also, I am not a developer but would classify myself as a phone nerd and I'd like to think I'm not totally helpless here. But, that has been the outcome of every attempt to fix the problem up to this point. Out of curiosity I even tried to upgrade using V35 firmware figuring it was worth a shot but that didn't work either. LGUP likes to remind me that nothing seems to match and that I am a moron for not looking closer at rhe phone before I bought it. Live and learn I suppose. Hopefuly.
Thanks for any help anyone can offer.
I'm only guessing but it sounds like one of the abl_a or abl_b partitions have the v35 engineering fastboot installed perhaps?
Can you get into fastboot? Does the phone display a LM-G710... model in fastboot? If it displays a V35 model than thats why
The v35 gets put onto the abl partition when people want to unlock the bootloader via the EDL (9008) method.
If thats the case you need a G7 abl partition copy. If you get into EDL mode and reflash either or both of the abl partitions and laf partitions you should be able to get download mode and then flash a rom using LGUP. (laf partitons contain the download mode)
I understand the bootloader is unlocked but if you read a G7 guide on unlocking the bootloader what I've been saying might be a bit clearer
Greetings everyone, I've been using my device for about four months now on a stock firmware and lately got bored of the Oxygen OS so I've decided to give custom roms a try, I opened the developer settings, went for the oem unlock, enabled it, got debugging enabled also, went to fastboot mode and tried both fastboot oem unlock and fastboot flashing unlock with no luck. It asks me for an unlock token. I know for a fact I'm not on a TMO software, I'm running LE2123 with a locked bootloader and I've never touched firmware or never converted my phone from a certain software version. I've filled a form on the oneplus' token unlock website and now waiting for an unlock.bin.
My question is how even the seller I got the phone from converted TMO to LE2123 without an unlocked bootloader? How am I unable to unlock my bootloader on a EU firmware and will there ever be a possible brick if I used the unlock bin on a LE2123 rather than a TMO 2127? Is there a way to convert an EU firmware to Global so that I'll have a chance unlock my bootloader?

This same exact thing just happened to another guy. He found out his rear sticker was indeed showing LE2127. To my (our) knowledge, only the le2127 needs an unlock token and was the only carrier branded 9P at all. While you didn't change anything, it's likely the seller did before you purchased it. Check your back sticker.
You can convert Le2127 to Le2123 without unlocked bootloader using the Tmo->Eu conversion tool. You may need to run that same MSM tool (or a custom one for different targets) and bypass the token unlock.bin or wait for OnePlus reply with your unlock.bin. To further confuse this, I've read that the automated tool on OnePlus website is providing the wrong unlock.bin and people are using support email or support chat to get the right one.
It is possible to unlock the bootloader without the token, while on oos11, using the tmo->eu msm conversion tool
There's always potentials for bricks when flashing anything. Make appropriate backups of partitions with the msm tool.
And yes, it's possible to go from Eu to Global. But I think you should try to run the Tmo->Eu msm tool if you're looking to bypass the token. You may want to go back to stock Tmo using the regular Tmo msm tool first. If both the stock Tmo MSM tool and Tmo->Eu msm conversion tools don't work, you may need a custom MSM tool for target change but hopefully that's not required for this situation
