There's a 20e image as well. I posted it on top of the post.

Make sure you download that file and rename it to something easy like twrp20e.img put it into your /sdcard/

Then hopefully you're on 11g, boot into the 11grooted image and flash that via fastboot flash command:

fastboot flash boot_a (the rooted 11g boot image)
fastboot flash boot_b (the rooted 11g boot image)

Then boot into the rom fully then restart to fastboot.

Then flash the twrp20e image.

fastboot flash boot_a twrp20e.img
fastboot flash boot_b twrp20e.img

Then immediately reboot to download mode and it should pop up!!

I didn't made this tutorial, all credits to user 机锋网友8051_ABD

I managed to install Your TWRP on G710N with Korean tutorial from other site. In G710N fastboot showed for me only if install partition dl boot_a and boot_b with LGUP from G710ulm11g when other ROM is installed.

0. Shut down, press and hold the volume + insert the computer data cable

1. Download mode, G710ULM20e, partition dl select all, press and hold the volume + again to enter the download mode

2, download mode, G710ULM20e.kdz, and re Volume + enter download mode

3, download mode again, G710ULM11g_01_NAO_US_OP_1112.kdz, dl: boot_a + boot_b, press and hold the volume-and power button to confirm twice after trying to enter dual-clear mode, but will only enter fastboot

4, fastboot mode,fastboot flash boot_a ulm20e_magisk19300_twrp_op_unlocked.img

fastboot flash boot_b ulm20e_magisk19300_twrp_op_unlocked.img, press and hold the volume + after entering the download mode

5, download mode again, partition dl G710ULM20e.kdz, select all and uncheck boot_a, boot_b

6. The first time you enter the system, you may not find the mask magic. Restart the system

.After entering the system a second time, there was a license agreement with a Korean version of the operator. After agreeing, I entered the desktop and saw magisk appeared. At this time Connect to wifi, run magisk, you will be prompted to install, agree, and then restart a series of upgrades

To fix Wi-fi:

*#546368#*710# -->field test-->wi-fi--> ota updates and check JP -->save and restart

tested LineageOS 16, wi-fi and lte doesn't work and there is no fix.

Has anyone flashed a rom on the ulm after unlocking the bootloader (and not go back to 20e rooted)?

The memory management has gone to **** on stock for me. Tabs reload when switching back and forth in the browser, music doesn't resume after phone calls, maps quits working and doesn't give me directions. It's a real **** show and it used to be fine.

NVM, figured it out and made a tutorial here

[LG G7 ThinQ  Guides, News, & Discussion] Awesomeslayerg:
You can but so far i tried AOSP from Phhson and PixelExprience it boots with the original vendor_gsi but its kinda broken. Like it freezes after a couple minutes and the dialer doesnt work. If you try flashing carbon vendor it bootloops.

Would any generous soul be willing to backup all but userdata partition using the Partitions Backup app and upload it for us to download? That way we can flash all the partition image files via fastboot, to make it faster and easier. While I'm not sure if it'll work, I don't see harm in trying, seeing as we'll keep download mode just in case.

I don't think we can fastboot flash all of the partitions only system, data and boot and maybe vendor. I've done that and bricked my phone cause there were tons of bootloader files.

As of right now I'm uploading stock ulm20e system.img ,stock vendor and a twrp20e img

You can flash them in twrp or fastboot

Been figured out after many time tried to root the firmware version 20e android 9 on my g7 ulm model, and i realized that i don't need to flash the twrproot.img on boot_b also, bcuz flash on both boot_a and boot_b will and update the firmware version from 11g to 20e will result in fastboot/bootloader mode bootloop, and magisk will not install, to get it work in correctly way, you have to flash the .img file on boot_a only, not boot_b, then update the firmware to 20e using partition dl, choose all, and exclude boot_a and boot_b, then you good to go ;)

anyway I'm re making a guide of how to root on version "20e" all model except T-Mobile.

after you cross install to firmware model "20e" and downgrade to firmware version "11g" did you enable the "development option" with "usb debug", unlock bootloader first and install magisk on firmware model "11g" in in order to install .img on boot_a and cross flash to "20e" again? it you don't, your device will result in bricked and damaged.

I already have a bootloader unlocked G7 flashed with a rooted ULM20e, If I read the tutorials correctly, in order to be able to install TWRP and get back fastboot I'd need to flash Twrp-Magisk_20e(9.0-Pie)_boot_a_only.img in boot_a and the a rooted 11g boot image in boot_b (could do that from the phone directly with dd) would that be correct or did I miss something?

same as g710N, then can you please try install the g710ulm20e first then use partition dl in patched lgup or lgup dualmode, select all then exclude boot_a and boot_b, or u could try flash the 20e using the partition dl , exclude boot_a and boot_b then downgrade to 11g, then follow the g710ulm unlock bootloader instructions then patched the twrp-root boot.img then upgrade to 20e again. pls report back it it's work

i guess different model now cannot use different firmware with different boot.img on android 9, so I'm sorry about this, maybe you could try cross-install to firmware version model "11g" and root it to wait for lg ux 9 android 10 to bring back fastboot.

Sprint LG G710PM bootloader unlock and root

I have a LG G710PM originally from Sprint, recently changed to T-Mobile. I was able to manually add APN to get phone receive mobile data, but after I did factory reset two days ago, would not allow T-Mobile APN and mobile data (phone call still works). I thought root this phone to may allow me unlock G710PM to other unlock firmware such as G710ULM then to receive mobile data? I follow this link and simply could not get into desired fast boot mode, always reboot into regular phone. How can I get mobile data fixed (or at least allow me manually add APN for TMobile?)

Note:Sprint store unlock this phone by IMEI #, now no one from Sprint/T-Mobile/LG could or willing to help me... I exhausted two days time wish gurus here to save my doom days...

First of all, thank you [MENTION=9932647]CyborgSG[/MENTION] for this guide!

In step 1 of the root guide, you point to the following URL to crossflash the firmware to 11g:

[LG G7 ThinQ  Guides, News, & Discussion] CyborgSG:
hey guys, i just came and want you all to know that the reason why i did delete the bootloader unlock on 11g is LG now has fuked up their software and the fastboot, they did set fastboot to oreo firmware only so i thought pie firmware didn't have fastboot but other user report that pie firmware have fastboot on some models, which is why LG is make it even more harder to unlock bootloader and root.

[LG G7 ThinQ  Guides, News, & Discussion] way2aware:
It means that you're trying to run a SU command without root. If you downloaded the rooted boot img, and can boot into fastboot "adb reboot bootloader" then run "fastboot boot 710ULM11g_rootedboot.img". When it reboots you'll have temporary root. Run the shell commands then, as SU.

Also, do not update magisk to the latest version when you are temporarily rooted with the rooted boot img. It won't work. Instead use an earlier version of magisk such as magisk manager version 6 and magisk version 19.2. Then it should work to give persistent working root., after which you can update magisk to the latest version. But this is after you run the SU commands, as directed in the tutorial

Ok I'm confused now. There are links to guides that seem to no longer exist and I'm trying to figure out what methods if any I should use. I have a 20e ULM phone currently (was originally a pm flashed to ulm on eBay, then I updated to pie using the patched lgup).

Can I get root on 20e or do I need to flash to another firmware first and follow a different method?
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
You can root it. Is your bootloader unlocked already? Then yes if no unlock the boot loader.

Anyone can cross flash to any kdz which in your case seems they did.
[LG G7 ThinQ  Guides, News, & Discussion] Dishe:
Yes, they did and it seems to be very popular on eBay to find this, specifically pm versions flashed to ulm. But oddly enough the serial number is blanked out. I'm not sure if that's a side effect of cross flashing or if they used some other methods to clear / unlock / etc as well. How would I check if my bootloader is unlocked?
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
Phone info may say modified or when it boots up you get this message.
[LG G7 ThinQ  Guides, News, & Discussion] Dishe:
Oh, no I don't get that at all. My wife's v20 does so I guess that's what I'd be looking for. :/

Ok so assuming my bootloader is NOT unlocked and I'm using pm hardware currently flashed to the latest ULM 20e. What instructions do I follow? I'm not new to rooting but the only LG I've done (v20) was very easy to follow. I flipped through this thread and I must admit that I don't really recognize a lot of the terms being used (abl a, b, etc... In the past I just ran a script or something that put twrp on and then flashed magisk).
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
The terms being used are partitions. When they talk about extracting a kdz to get the dz file and extract that it contains the partitions which are actually .bin files you change .bin to . img you get boot_a or boot_b. Or what ever partition you want (ex.abl_img or laf_img).

Google and you'll get what each partition pertains to and what it does.

boot_a is a slot

boot_b is a slot

Your phone is dual slot I believe. I will share a guide so you can use to bootloader unlock your device.
[LG G7 ThinQ  Guides, News, & Discussion] Dishe:
Looking forward to that guide.

It's weird, I've been tinkering with this handset as I do all new (to me) handsets I get, but I'm finding that information on the forum is sort of spread out and harder to follow than I'm used to. Like, my phone was stuck on Oreo when I got it (likely due to the missing SN), and I had to flash Pie using LGUP, but the thread with instructions to do that was sort of aimed at doing something else (crossflashing devices with European Pie, etc. It wasn't immediately obvious this had anything to do with my dilemma, and I had to dig deep into the thread to figure out how it could help me). Now I'm trying to find root information and I'm finding conflicting threads about how to do it, and one in particular pointing me towards a thread that's about unbricking and not about bootloaders or root, saying THIS is the recommended method now. But my phone isn't bricked so I don't understand?

I honestly usually don't find it that difficult around here, I feel like we need some mods or FAQ people to sort out this corner of XDA!
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
It hasn't been long since the unlock method and the firehouse file for qfil was released to unlock bootloader.

Yes there are several guides out there people wrote them with the intention of helping all users with the thinking that people would take the time to research on there own.

I unlocked my bootloader crossflashing to ULM11g using fastboot. Then I cross flashed back to Verizon and figured how to root Verizon on my own using qfil. Alot of my ideas came from reading other forums or threads that took the time to share there methods.

Check your PM.
[LG G7 ThinQ  Guides, News, & Discussion] Dishe:
Interesting! Yes, I saw your other thread about the Verizon thing. I got your PM, but I think you should start a thread specifically about this so we can comment/ask questions, etc. For example, the guide makes sense to me, but then am I stuck on an older firmware? I'm on 20e now, would I be able to go back to 20e or would that lose root?

Also, since my device is a PM that was sold as ULM (and is missing the serial number as a result it seems), I was stuck with an Oreo firmware until I followed this guide to using patched LGUP:

https://xdaforums.com/lg-g7-thinq/development/rom-how-to-install-pie-stock-treble-aosp-t3914079

If I'm understanding correctly, I just need to use the LGUP I already have to flash that 11g kdz, then continue with the guide.

Additionally, I noticed that firmware is from the BPT versions, which I'm confused by. Especially if we get stuck on that version for root, what is BPT and how does it differ from the FI / US versions?

We need a thread to discuss so I don't take over this one! LOL
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
As long as your bootloader is unlocked you can pretty much crossflash any kdz and root it except TMobile that would cause a brick.

You only downgrade to the ULM11g to have the OEM unlock selection in developer options and 11g boot.img is already rooted.

I use other kdz that work with Verizon I find that out by flashing different kdz's and I'll root that if I want to like a GFI kdz.

If you bootloader unlock successfully crossflash to a global kdz and root it with qfil.
[LG G7 ThinQ  Guides, News, & Discussion] way2aware:
I think the issue he's having is that there are no longer any clear written instructions to attain root in this thread like there were before, and thus, the thread is now misleading because of it. It advertises something that it doesn't deliver, due to the folks who have deleted their tutorials helping others to get root, on pie Roms.

Edit: also wanted to thank you for pointing me toward qpst/qfil the other day, spent a bit of time getting familiarized with it bricking and then unbricking, but still haven't succeeded in my goal of having a g7thinq, operating on Lineage with magisk installed, and persistent twrp.

I'm still working toward it though, it is without doubt an extremely useful tool as you'd mentioned.

You have to do one of the following:

Disregard, doing the following will lock you out of download mode and stock Pie boot img don't support fastboot..

In ADB, according to this guide:

Permit 'Shell' in Magisk superuser access AFTER executing the following:

adb shell su dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf_a
adb shell su dd if=/dev/zero of=/dev/block/bootdevice/by-name/boot_b

Or

With V35 eng bootloader flashed with QFIL; this is riskier:

fastboot erase laf_a
fastboot erase laf_b
