Worked like a charm on Verizon G710VM!

But don't update to Verizon Software.

This didn't work for my Google Fi G710ULM, it says "Sending 'boot.img' (23712 KB) FAILED (Write to device failed (Invalid argument))

Anybody successfully root the Sprint G710pm with this method?

Is your device bootloader unlocked yet?

I did, which is why i included sprint instructions also.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
Bootloader unlock worked great, but after upadet to VZW Pie got working rom and official VZW fastboot, that don't take any commands (fastboot failed (remote unknown command).

So i can't neither boot laf directly nor reboot to slot b (in which download mode works)

So better to stay on ULM
[LG G7 ThinQ  Guides, News, & Discussion] themchn:
I flashed the 11g oreo kdz with LGUP so yes? I can get into the bootloader with "adb reboot bootloader" but in there with fastboot after running "fastboot boot 710ULM11g_rootedboot.img" (I do have the file in the same dir as fastboot) it returns "Sending 'boot.img' (23712 KB) FAILED (Write to device failed (Invalid argument))

fastboot: error: Command failed". I've enabled USB debugging and OEM Unlock within android itself as well.
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
I had the same issue on my amd ryzen pc. I ended up switching to an intel pc with newer version of fastboot to get it to work.

But you can always try switching usb ports and making sure your drivers are up to date and fastboot also.
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Does vzw have oreo kdz? Seems pie versions block fastboot or dont allow fastboot commands to work.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
Yep, you're right, pie bootloader from VZW rom blocked all commands.

You can write engineering bootloader from v35 to laf_a and don't update it, with normal bootloader (not vzw) you will have working fastboot and can easily switch to download mode just with activation of 2nd slot.

But not vzw,

I'll think that i will just wait next OTA
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
You cant write to laf partition without root lol. Also bootloader goes in abl_a not laf.. Laf is for download mode. Unless you wanna brick and be stuck in 9008 mode.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
You mean from rom? Cool, will try it! The main point to do this - overwrite laf_a partition that it's boot directly to fastboot (because adb reboot bootloader not working). It worked great with ULM and US cellular, but not with VZW for Verizon.

Just to be clear, for update to Pie abl_a and abl_b must be stock, because v35 bootloader not made for Pie

Permission denied for writing laf_a :(
[LG G7 ThinQ  Guides, News, & Discussion] themchn:
You're a life saver. Plugged it into my linux laptop with intel and every worked like a charm. Officially have an unlocked bootloader.

Anyone know if there is a safe way to have permanent root on any of these devices at this point?
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
When you boot unlock then you wanna boot back up again with the rooted boot image and use magisk to update root.

This then will root your actual boot image or you can fastboot flash that boot image to have root the easier way.

As far as vzw or anyother you have to manually root the boot image from a pc.
[LG G7 ThinQ  Guides, News, & Discussion] themchn:
You are the man! Your guidance has been very appreciated. Now to keep my eyes out for a good pie rom to run.
[LG G7 ThinQ  Guides, News, & Discussion] 2kool2Bcruel:
Thank you for confirming Sprint.

I don't know if it makes a difference or not but last week there was an ota system update that I installed. Any reason that update would cause issues with your guide? I attached a screenshot of the settings info showing the baseband, kernel, etc.

I appreciate your help. This is exciting. I've wanted to root this phone since I got it over a year ago.
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Are you still on the original sprint firmware??

If so pm me so we can try to backup the os.. And no the update wont cause an issue as it was a security update.
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
We can root any firmware with a kdz available. But with this method in the tutorial its all about if you wamna go thru the trouble to update and root.

This is just a much easier way to be rooted then to be going thru the obstacles or pay someone a "donation".
[LG G7 ThinQ  Guides, News, & Discussion] way2aware:
Thank you man, for your tutorial here. I had begun to accept that i might not be able to fully own and be in control of this phone... Hardware wise the best ive ever owned.

And well played, sir
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
There's no problem to get root on 21d with your tutorial, I've made it in a little awkward way, but it's worked for me: I've flashed only boot_b from 21d on 11g rom, booted with patched boot for 11g, pulled boot_b to sdcard and patched it with magisk. Then I've pushed it to boot_a and boot_b and flashed 21d without boot. With stock abl.

One more thanks for this tutorial!
[LG G7 ThinQ  Guides, News, & Discussion] dexx121:
Nice work. If you could write up a more detailed tutorial on your process, it would be appreciated.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
What i have done:

after bootloader unlock went to stock (i have to make factory reset 3-4 times before LGUP can see my phone other than "unknown")

Connect to LGUP and flash only boot_b using Partition Dl

Then boot with 710ULM11g_rootedboot.img:

fastboot boot 710ULM11g_rootedboot.img

With adb go to adb shell and pull boot_b:

adb shell
su
dd if=/dev/block/bootdevice/by-name/boot_b of=/sdcard/boot_stock.img

Launch Magisk app->install->choose and patch->choose stock img

Then push patched rooted image to boot_a and boot_b:

dd if=/sdcard/download/magisk_patched.img of=/dev/block/bootdevice/by-name/boot_a
dd if=/sdcard/download/magisk_patched.img of=/dev/block/bootdevice/by-name/boot_b

In the end flash new ROM with LGUP in Partition Dl mode and select all besides boot_a and boot_b

P.s. You can skip pulling stock boot and extract it from kdz using https://xdaforums.com/showthread.php?t=2600575

or you can use attached files http://bit.ly/2lZSUAr

P.p.s. I made it in such awkward way because last time i messed up with fastboot and download mode and have to pay for Octopus.
[LG G7 ThinQ  Guides, News, & Discussion] inserterikhere:
I'm having an issue with this method. Every time I flash boot_b, it boots normally, but once I adb reboot bootloader then fastboot boot, it wont boot. It only stays on the "Life's Good" screen with the blue led blinking. I can recover by flashing the boot_b from the 11g img.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
Did you flash new ROM?
[LG G7 ThinQ  Guides, News, & Discussion] inserterikhere:
In the end I managed to do it in a different way than yours. From stock 11g, I booted the rooted img, update magisk, boot root img again, direct install magisk, then flash boot_b from 21d, pull boot_b, patch it with magisk, then dd it to both boot_a and b, and finally partitiondl 21d without boot_a and b. Thank you for your steps! Wouldn't have been able to do it without it.

Can somebody do a video how to root LG G7? Or maybe give more details, add photos how to do?

Edit: I did reach unlocked bootloader and phone rooted with success.
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
After a little trial and error, i have successfully rooted my lmg710ulm, couldn't be happier. A few tips for people brave enough to attempt this; If you get errors while flashing the old firmware try plugging into a different usb port, using a different usb cable, or even flashing on a different computer. It took me about 2 hours of fiddling around before I finally got it to flash.

Thanks so much for this thread!
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
Hey! Could you elaborate a little on how you were able to install lineage from the rooted firmware? I haven't been able to successfully install twrp...
[LG G7 ThinQ  Guides, News, & Discussion] zachd:
I'm a little confused about the process. Is there anything special about the firmwares from that lg-firmwares site, or do you simply need to be on the ULM firmware for the process to work? I'm currently running stock Android Pie on my G7 ULM. Since I'm already on a ULM firmware, can I skip the step of flashing to the ULM firmware, or do I need to be on Oreo for it to work?
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
I hate to say this, but research into magisk before even attempting this. A hard brick on a phone like this is not a good way to go since not all posibilities have been proven.

Nice lol it takes a while to find a good setup depending on the computer you use.

Follow the posts for lineage or aosp.. You have to be fully flashed to emw firmwares to make it work.

At this moment ULM does not have a method to use li eage coming from ULM.

I have a twrp that semi works with ULM but i havent bothered to make it fully compatible.
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
Yeah, I flashed the European 9.0 in hopes to do just that, but I can't seem to get into the bootloader again, even though it still says it's unlocked. Do I have to install an older version of the European software?
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Not every model is capable of having fastboot across all firmwares so we have to resort to using lgup 1.14 to use partition dl to flash certain partitions to change to whatever firmware and keep fastboot.

You may lose your serial number in the process which isnt a serious thing as your carrier does not require it to authenicate.
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
That sounds pretty complicated, do you have instructions on how I would do something like that?

how to extract my boot.img without root but with open bootloader?

My phone don´t boot with any pre patched images.
[LG G7 ThinQ  Guides, News, & Discussion] joaovictor.me:
Can you please include that the bootloader can't be locked again? Some users are relating brick after try.

It's a totally irreversible process. Is common that user try to relock to send device to repair service.
[LG G7 ThinQ  Guides, News, & Discussion] jimmyStoo:
Hi, I have a few questions I'm hoping can be answered.

I have the ULM model with Pie, so do I need to still flash the ULM firmware?

Are these files safe and don't contain malware? 710ULM11g_rootedboot.img and flash abl_a

Am I free to flash any ROMs listed for the LG G7 or are there restrictions?

My goal now is just to unlock bootloader and flash Lineage. Is that possible?

Do I need to flash recovery?

Can I return to stock firmware and re-lock bootloader?

Thanks!

can you please take remote or whatsapp me?
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
Hey! I'm not an expert by any means but I got my bootloader unlocked just fine.

1 - Yes, I have the same model, but the root patch is for an older version of the ULM software so you still have to revert back to 11g

2 - I use avast and it didn't detect anything from extracting or flashing the files.

3 - If you have your G7 under warrenty DO NOT flash the files. If you brick your phone or otherwise damage it during the process it's not covered and won't be repaired or replaced by LG

4 - I'm still stumped trying to flash lineage, but I got the bootloader unlocked and reverted back to 9.0 for now. If anyone knows how to flash lineage I'd appreciate some help

5 - You don't need to flash recovery to unlock the bootloader. I managed to get twrp installed after the fact, but for whatever reason I couldn't access the internal storage once I got there. Wouldn't recommend it.

6 - Yes, you can revert back to stock firmware but I wouldn't try re-locking the bootloader (Although I'm not sure why you'd want to) as it may brick your phone

---------- Post added at 10:10 PM ---------- Previous post was at 10:05 PM ----------

It needs to be the 11g (oreo) firmware because you can access the bootloader from there.
[LG G7 ThinQ  Guides, News, & Discussion] jimmyStoo:
Thanks for your input!

So I'm assuming this is just to get root while using LG's stock firmware then...? What are some things to do after rooting on this fw? I can only think of installing adblock for now. I wanted to be able to install a cleaner OS like lineage so RAM usage is possibly less, and possibly fix the androidAuto crash that a lot of G7 users have.
[LG G7 ThinQ  Guides, News, & Discussion] TJzuo:
Yep. Honestly in my opinion I would wait until someone finds a way to put lineage on the ULM model because right now unless you're okay with 8.0 11g firmware it's not really worth it. At this point I'm seriously considering selling this thing and switching to something like a OnePlus 5t
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
You can downgrade to 11g with LGUP without a problem.
[LG G7 ThinQ  Guides, News, & Discussion] officerplonk:
Thanks so much for these instructions. I successfully unlocked the bootloader on my 710ULM and achieved permanent root with Magisk. and then broke it with factory reset, see edit 2 below.

Now if I understand correctly, in order to flash TWRP and a custom ROM as of today, I would need to do the following...

(steps 2-3 derived from [MENTION=3976166]jsergan[/MENTION]'s more detailed instructions in post #54)

Download European(?) Pie KDZ File (G710N20c_00_LGU_KR_OP_0107.kdz). (unsure: does it have to be the European one?)

Flash only the boot_b partition from the Pie KDZ using LGUP's Partition_DL mode.

Boot into my rooted 11a ROM. Copy boot_b, patch with Magisk, and then dd the patched version to boot_b and boot_a.

Reboot, verify everything still works.

Flash TWRP per https://xdaforums.com/lg-g7-thinq/development/twrp-twrp-3-3-1-0-lg-g7-thinq-t3954012

Flash a custom ROM

Is that right?

Edit: I just saw [MENTION=2914935]loonycgb2[/MENTION] mention in Can I put a roms... thread that "PM and ULM models seem to have issues with pie not loading bootloader."

Anyone who has experience to confirm/deny which versions of Pie (or all) result in bootloader not loading on ULM, please share.

Edit 2: broke my root I had to do a factory reset due to LG mobile transfer tool messing up. Now, the rooted boot image no longer works for me. I can boot it with fastboot just fine, but all requests for SU access just hang forever (whether from adb shell or from an app that needs root). Magisk manager says "Magisk is installed (-1)." Ideas?

Make sure the common dll file is in common folder inside "model" folder.
[LG G7 ThinQ  Guides, News, & Discussion] RichBordoni:
Are you sure it's locked? According to the Verizon site it seems they only lock phones 60 days from the date of purchase or less. If you're sure it's locked, try contacting the seller and asking if he or she would be willing to get an unlock code from Verizon. If they aren't, you can contact Verizon support yourself but I don't think it's very likely that they'll unlock the phone without the original owner's information. If you dont have any luck, you can try to use one of those paid unlocking service websites. I've never used one before and I'm not sure how legit they are... Maybe someone else can chime in.

Further info here.

Btw, to use a phone on a different network what you need is a carrier unlock. It's a lot simpler than a bootloader unlock. Also, as far as I'm aware, unlocking the bootloader doesn't automatically give you a carrier unlock as well. And it's not for the faint of heart because you could easily render your phone inoperable if you don't know what you're doing.
[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
I've used this one https://androidfilehost.com/?fid=11410963190603845019)

[LG G7 ThinQ  Guides, News, & Discussion] jsergan:
You can erase laf_a partition to get fastboot access, BUT you will loose Download mode.

Theoretically you can just boot slot_b to get back Download mode, so fastboot on slot_a and download mod on slot_b.

BUT some fastboots (like VZW) not receiving commands at all - you will stuck in fastboot that is useless.

Can anyone advise me on why LGUP Dual Mode won't crossflash for me? I did have a previous version of LGUP installed from when I rooted my V20, but I uninstalled that version and moved the driver to another folder before installing Dual Mode. It doesn't seem to make a difference whether I run LGUP in developer mode or user mode; neither will let me flash using UPGRADE. I had to use Partition DL to flash onto ULM, but now I'd like to reflash Verizon's last Oreo update, so obviously I'm wary of overwriting any individual partitions unless I'm sure it won't wipe out my root.
