LMG820UM AT&T "permanently locked" - Android 9 - LG G8 Questions & Answers

In order to have it Unlocked:
a) Can I extract the ROM of this device, have a kdz file and flash it again with that?
b) Was the booloader for this model released ?
c) Is there any other way, no matter risk to try to unlock it?
Thanks in advances.:good:
Edit 1:
"Users with the AT&T variant who are stuck on pie: temp root only works on android 10, as such you will unfortunately not be able to bootloader unlock your device. The firehose may leak at some point in a few months, and you will be able to unlock (and update manually) if it does."
That unlock is what I'm referring here?
Edit 2:
LG build a phone with specific hardware for AT&T? I think that no, that is not cost efficient... what LG do it's factory the LG G8, and next, ROM's are placed by seller like AT&T or Verizon, etc. AT&T use a quantum pc to do that... come on guys...
I know that LGUP could look sophisticated from some one, but real tools works on line command on linux... so if it's not there any way to hard flash a phone like this with a command line tool, with all the risks that a tasks like that involve, let's close this forum.
It's IMPOSIBLE that such tool be out of knowledge of legacy members of this forum... what happened here?

Rooting Moto Z Play (Unlocked) US

Alrighty, I'm not sure where to begin. I have a Moto Z Play. I am not sure all of the information exactly. I come from using a Note 3 for the past 5 years and haven't had to root or anything as of recent.
This is what I do know; it's running android 6.0.1 and the device name is XT1635-02.
These are my questions:
1. Do all Moto Z Play run on the same hardware?
2. Can I flash a Verizon rom to access CDMA bands?
3. Is there anyway to flash access to all CDMA/GSM/LTE bands the chipset is capable of reading?
4. Does the Unlocked Moto Z Play in the USA (From Best Buy) come with a locked bootloader?
5. How do I unlock the bootloader?
What program do I use to flash custom recovery, etc.? i.e., Odin and Kies for Samsung Galaxy Note 3.
6. Is there any way to pop-out the dual sim place and add the capability for two SIMs?
7. Is there anything else I should know, or questions I should be asking?
Thank you to anyone in advanced for helping me with this issue.
1. Mostly, yes. Could be differences in radios. There's also 32GB and 64GB storage options.
2. No. That'll probably brick your phone. If it doesn't, it still most likely won't enable CDMA.
3. Anything is possible, but it might require modifying hardware. Why not just get the VZW CDMA variant instead?
4. Yes. Your phone may be carrier unlocked, but the bootloader is always locked by default.
5. There are threads with bootloader unlocking instructions. In dev options, enable allowing OEM unlock, then go to command line (make sure you have fastboot installed), you'll input commands. Register with Motorola and give them some output, they'll give you a bootloader unlock code (free). Now your warranty is void. Now you can unlock bootloader.
5.1. Root and flash with the command line using fastboot. No Odin/Kies/GUI options as this is not Samsung.
6. You'd have to get a dual-sim tray, then flash another variant firmware (Brazil or India), then maybe...You might get imei=0 and then you're stuck not able to use the phone until you fix it.
7. Read the forums (start with the pegged threads). Study the steps before proceeding.

is the LG G710pm impossible to root?

Is this phone impossible to root or is there just a lack of interest in figuring out a way to unlock the bootloader? I love this phone but really miss the freedom I had on previous devices to install certain apps and run different roms. I've never had a device that has been out this long without a root available.
I guess what I'm asking is if I should consider going to a different device if there isn't a way to unlock the bootloader in sight or stick it out because it'll happen in the near future.

So far, no way to root it yet, I am stuck on the Sprint G7 myself and currently fighting with Sprint to allow me to swap to another device. I know it wont work but at least I am voicing my dissatisfaction of this device with the lack of timely updates (still on November security). If I had known now when I went to Sprint back then, I would have never chosen the LG G7. The phone itself is decent, hardware is good but lack of root, lack of bootloader unlock, and lack of timely updates make the device unusable in my opinion.
I personally am hoping I or someone else can find an exploit for ROOT and eventually bootloader but so far, not much traction has been made in that department.
I have a g710pm, running Android 8.0.0
I see in developer options there is a selection that says, "Enable OEM Unlock" wouldn't that unlock the bootloader?

Nope it will not limited fast boot won't let you run the command its basically useless
You can take a look at my post, there are all the models in my country to unlock BL and ROOT, but only in the hands of a few people, they do not intend to share this, and through this to get benefits, they provide remote unlocking and ROOT services , but need to pay, which is expensive for me, I don't know English, sorry, the reply is translated by Google...
Hey everyone! As I had said earlier, the rumors are true, most G7 variants can be bootloader unlocked. I searched many Chinese websites that had already shown rooted G7 phones but showed no clear methods besides "remote unlock services". Now the method is known! The engineering bootloader from a very unique AT&T V35 V35AWM model (abl_a and abl_b) is flashed via an Octoplus box on the G7 when in QDLoader 9008 mode. This guy from Ukraine motogvasyag posted his methods on 4pda.ru and are now on XDA here: https://forum.xda-developers.com/lg-g7-thinq/how-to/to-unlock-bootloader-root-models-t3928505
Please check out the thread, and do donate if you can. He is doing these Octoplus flashes for free.
**This method won't work on T-Mobile model (G710TM and others). I'll still be on the lookout for any T-Mobile methods.**

About all versions of LG G7 unlock the bootloader and ROOT discussion

I am from China, I don't know English, this article is translated by Google, but I hope you can read it.
In our place, there are technologies for all models of G7 to unlock bootloader and ROOT (T-MOBILE version of the phone needs to be replaced with a cup to become a general version to unlock the bootloader, because this version of the phone cpu is encrypted), but, frustrating Yes, this technology is only in the hands of a few people, they do not intend to share, and they use this technology to gain benefits.
They provide remote unlocking of the bootloader and ROOT services, but need to pay 150 yuan, which is expensive for me and is meaningless.
I bought a G7 from a second-hand merchant who replaced the RAM with 4G and changed it to 6G. He said that the machine replaced the T-MOBILE version of the CPU, but the IMEI code displayed on the machine is the Korean blue version, and my G7 is Red, I don't know if G7 has changed the IMEI code. If so, please let me know, thank you
My mobile phone, the merchant has helped me unlock the bootloader and ROOT. And, since someone on XDA has shared the cracked version of LGUP, I can use it to brush in any version of my G7. I brushed Korea, T-MOBILE, and KDZ in Europe, and in Europe and Korea. The version of the system ROOT, because now only the European version and the Korean version of ROOT BOOT, I brushed into the boot through FASTBOOT, but, very strangely, I brushed the three versions of KDZ, only T-MOBILE version KDZ can enter FASTBOOT via ADB commands or keystrokes (maybe this phone is T-MOBILE version), other versions will only restart. Therefore, I have to first brush into the T-MOBILE version of KDZ into FASTBOOT to brush into the version of ROOT BOOT I want, then brush into the corresponding version of KDZ, and then install magisk, you get ROOT. However, I am not satisfied with the current system version, I want a newer version, and make it ROOT BOOT, I brushed KDZ many times, when I entered FASTBOOT again into BOOT, I found that I can't brush BOOT again. And FASTBOOT prompts to open the OEM to unlock
So, I entered the system, clicked on the developer option, found that the OEM unlock option has become gray, and can not be opened, so my phone can not be brushed into BOOT, I am looking for ways online, unfortunately, I have not I found a way to succeed. Later, I saw the latest V30 unlocking Bootloader post. It seems that after unlocking the bootloader, the OEM unlock will turn gray. It will take a few days to open again. However, I didn’t see it. Before the V30 post, I have already entered my G7 into FASTBOOT and re-locked the bootloader via the adb command.
Now I can open the OEM to unlock it, but it is useless. Because the bootloader is locked, I still can't brush it into the BOOT through FASTBOOT. Because the bootloader has been locked back by me, I did this, I thought my G7. Is the T-MOBILE version of the replacement CPU machine, in our case, it is said that after the T-MOVILE version of the machine to replace the CPU, T-MOBILE G7 can unlock the bootloader, and will not lock
Now, I am trying to find a way to unlock the bootloader, but no, yes, no, I hope to get some clues to unlock the bootloader by contacting those who have remotely unlocked the bootloader and ROOT by paying. However, no one wants to do this, they I even told me to go away, maybe because they have already paid to unlock it, and telling me will damage their interests. Finally, I learned about the process of remotely unlocking the bootloader by one person. Those who master the technology to unlock the bootloader do not want to expose it. They help the remote unlocking of the bootloader and block the operation process, just through the chat software. Release the command to let you connect to the computer or switch the phone into LG's brush mode, etc. I want to get some information through the screen of the phone. Unfortunately, that person doesn't remember, I only asked some strange news, that person's The mobile phone is a Korean mobile phone that does not unlock the bootloader. The mobile phone version is Android 9.0 South Korea's 20c. The remote flashing machine does not know how to enter the Korean version of FASTBOOT on this mobile phone that does not unlock the bootloader and ROOT. As far as I know, the Korean version The FASTBOOT of the mobile phone is hidden and cannot be opened by the command. This thing has been said on XDA... This thing makes me wonder, I thought they used the tool to brush into the European version of the system and then enter FASTBOOT to unlock. (Unfortunately, my G7 can only enter fastboot by brushing into the T-MOBILE version, the European version cannot pass the adb Or in the form of platinum enter). Some time ago, someone discussed on xda how to unlock the bootloader by brushing into the European version of the system. Since the cracking tool did not come out at the time, they hoped to use the octopus box to brush into the European version of the system and then unlock it (how to unlock without explanation), now crack The tool came out, it can make our G7 brush into any version of the system, but the discussion is gone...
If you have any ideas, please let me know and send it to this mailbox at [email protected]. I am not very good at using xda, and I need vpn on xda. I also need to pay for using VPN. I am poor, this is for me. It’s too much trouble...
*I have a few questions that need your help, 1 how to change the IMEI of G7, I want to try to get a network upgrade by changing imei to the corresponding system version.
2 How to unlock KDZ of G7, I need to unlock KDZ of G7 to extract BOOT.IMG into ROOT BOOT, I tried new methods and some old methods that I can find in my country to unlock KDZ of G7. failed
If you have a method, please let me know (hopefully have a tutorial), I hope to get your reply, thank you...
thanks for your sharing。
Intresting things they do in China. This is why I never trust buying a chinese brand. I bought in 2015 3 xiaomi mi3 mediatek clones from official shenzhen mi store. Never trust chinese brands again. That applyes for software also.
What version of kdz do you want? I have most versions from European model and 2 versions form Korean pie.
Update instructions, I used my friend's Korean version G7 to brush into T-MOBILE version KDZ tiles, can not boot, now only into 9008 mode, now confirmed that the replacement of CPU G7 seems to have become a strange machine, it seems that it can be cracked version of LGUP into any version of KDZ will not tiles, but other machines can not, such as my friend's Korean version machine brush into T-MOBILE machine. It will change into bricks, but one thing is certain that KDZ of Korean and European machines can be brushed into each other, because the publisher of LGUP cracked version is using this tool to make European G7 brush into Korean G7 9.0 system, but it is possible to brush KDZ randomly into Korean G7 system. I do not recommend that you do so. I do not think you have the hope that your machine will become a brick. If it has happened, I'm sorry, I can only say that, but I hope you can share it and let those who have not happened avoid it. I need more communication and look forward to your reply.
It has entered 9008 mode. Can I change it to European IMEI and ID, then get the unlock file, brush it into European system, and turn it into a European machine, then unlock BL. In theory, the hardware of G7 is the same... I hope someone can share the IMEI and device ID of the European version G7 to me. It's better to have unlock.bin file. I want to test it. My mailbox is [email protected].

That will be verry nice. Is it ok if I give you one from one g7em un retail mode but that has sim enabled?
Any update on this? Would be an interesting method, i would absolutely do this if it works

No you can't. Starting with SD845 - IMEI and ID stays in CHIP and regenerates on every boot.
So, the only way to achieve it is to contact this taobao seller and he will resolder EU chip, flash EM firmware and unlock it and then re-solder back your chip and you will have EM firmware but IMEI and SN will be 0.
N.B.:Regarding G7 it is build in 3 factories and has 4 different Hardware revisions so stop thinking HW is identical and simply cross-flashing will do the trick
So no way to sim unlock the lg g7 tmobile?
lmg710em unsupported country
Greetings everyone;
Since my lmg710em is registered in an "unsupported country"; I cannot unlock my bootloader with official way. I've looked for hours to find an unofficial way but there is nothing... I have tried to flash France's kdz, but nothing changes. Does someone have the european version's unlock.bin file? This is my only hope for now.
It's really bad to be forbidden to use the device, which you paid for, as you like.
I really need help guys,
thank you all,
cheers...

"Fastboot oem unlock" does not works :/ I have already tried it. The output was "unknown command" or sth like that as I remember. Was there any other step before cmd prompt section?

Question Cross Flash

So i have the tmo op 9 pro and I used to make cross flash zips for the lg v30 and op 7 pro sprint. I wanted to do the same for this device as well but since the bootloader unlock is a little different, I had some questions. Since I was able to bootloader unlock by bypassing the sim unlock the using MSM to convert to EU I was worried I would lose the bootloader unlock in the process of this. Basically I want to take a stock tmo payload.bin from A11 and then unpack it and use the imgs inside (minus the device specific ones of course) and make a twrp flashable zip so I can go back to TMO firmware. What I'm worried about is since I didn't sim unlock I would lose the bootloader unlock in the process. Any thoughts on this?
Bump
I'm wondering the same thing. I'm on tmo op9 pro as well. Unfortunately it updated to a12. I got oem unlock button when that update came tho, but it still asks for the unlock.bin... I put in for my unlock code to op, got it back but haven't tried anything yet. I also do not have SIM unlock as it hasn't been 40 days of activation yet, and the phone is not paid off. I was also an op7 user and it was way easier to get this done. I would like to have root again soon.....

Question Why can't I unlock my bootloader on a LE2123 software?

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

Thanks for the reply, much appreciated. I really did search the forum about the problem I'm running and couldn't find a solution, well should've looked deeper I guess. Will look into the article you mentioned.
