no. we need to get ulm vendor modify it as loonycgb2 said.

Im a bit screwed currently and cant help. I was planning on getting a ulm version of the vendor partition for the GSI roms. Buuuuut I wasnt thinking and relocked my bootloader trying to flash the persist partition (it said cant flash in unlocked state, so i stupidly locked it). I had [MENTION=3652704]Vlaaaad[/MENTION] fix it for me, but now i cant access fastboot after flashing pie when i could previously.

I guess im stuck on stock for now:crying:
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Flash back to ulm11g and you will have fastboot access again
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
Yeah, i did that, but i loose it again going to 21d. That didnt happen before.
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Its what happens when u unlock a non official unlockable device.
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
well i flashed 21d twrp/magisk to boot from 11g then flashed all of 21d but boot using partition_dl. I kept getting the decryption unsuccessful error on OS bootup after I decrpyt the data partition by wiping it in TWRP. the only way around is to flash a magisk only boot_a which allows the factory reset to run after the decrypt error, but then its encrypted again!

Any bugs on lineage os 17? Vibration is working ok?
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Might have to make a small vid of your rpcoess to identify the problem cuz even with octoplus guys they flash your phone the same as what we do but with octoplus..

So it should not have changed anything, you might be missing a step.

I litterally flashed back to ulm11g but was already boot unlocked so didnt flash the bootloader, just skipped to fastboot flash 20e twrp to boot_a then used kdz to flash everything but the boot partitions.

Then let the phone start all the way till it got to setup, then restarted to twrp.. formated userdata then flashed dm verity zip, then booted to os after wiping cache and was fine.

+1... someone can post a mini review please , about bugs , working camera and battery

btw great work, nice to see some movement here
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
google camera didnt work.

battery was fine

i dont know about vibrate

it had a weird lockscreen bug where the screen turns off after its unlocked. It sounds like a ULM version of the vendor gsi img would fix these but i cant seem to get it to work.

Ok, I installed lineage os 17 on g710n and LTE is working but Wi-Fi isn't also doesn't work wide lens in camera. Could You help me with installing gapps? I donwloaded pico and it says that I don't have enough space for it and I tried to resize2fs from Your tutorial but it gives me respond that there is no such directory.
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:

Can you help me, how to unlock bootloader on g710n, i have kdz ulm11g but can't have fastboot access. Thanks you^^
[LG G7 ThinQ  Guides, News, & Discussion] loonycgb2:
Did you flash to ulm11g kdz or did you just download it
[LG G7 ThinQ  Guides, News, & Discussion] ThuyenDuongAn:
I have kdz ulm11g but cannot access fastboot mode
[LG G7 ThinQ  Guides, News, & Discussion] Aseiel:
Only way to unlock bootloader on g710n version is to buy it already unlocked (often refubrished version for example) or You can find telegram group for unlocking any G7 with octoplus but You have do it by teamviewer with Someone who owns octoplus and pay for it.

Today I tested android 10 gsi on g710n with differnet vendors to make Wi-Fi work. Android 10 gsi with carbon vendor bootlops. Works with stock vendor (Wi-Fi not working, LED blinking bug) and vendor from this thread (Wi-Fi works and if RIL doesn't works you need to wipe, LED blinking bug ).

To install gapps I had first to resize2fs dev/block/sda22 from sirbow tutorial.

So I installed lineage os 17 again but with carbon vendor and RIL, Wi-Fi, led, battery and gcam is working fine. I had one hang of chrome APP but closed and reopend and so far is fine, this happened once. Location isn't working and google maps has bug with super large ui.

Nowe testing Evolution ROM x4.0 by Express Luke and so far is best. Remember to wipe cache or RIL will not work.

Vibration is not working and You have sometimes short blackscreen on unlock.
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
ok, little update here. I finally got the force encryption disabler to work. I used the method here https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit to get root on 20e. then i zero'd out laf_a and boot_b to get fastboot back. they were zero'd out using dd if=/dev/zero of=.... (i actually did this on 11g, and then skipped boot_a boot_b and laf_a on the partitiondl to 20e, same thing though.)

I get to fastboot by holding vol up on boot, DL mode is reached by switching to partition b and holding vol up on reboot.

I had to get fastboot back on 20e because the TWRP userdata format wasnt working. fastboot format userdata, however, on certain fastboot utility versions, did work, and i was able to flash the decrpyt zip and back up the vendor partition (drive link here). I backed up my vbmeta (drive link here) and dtbo drive linkfor the next steps as well. Those are 20e ULM files for the record.

I then did the following to flash a GSI

fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta_a.img

fastboot flash vendor_a vendor_a_20e_decrypt.img

fastboot flash dtbo_a dtbo_a_20e_decrypt.img

fastboot flash system_a system_gsi.img

fastboot format userdata

fastboot reboot

I let it boot then went back into TWRP to install gapps.

But vibrate and google camera are still broken. we'll need a custom something to get this to work. Basically just continue Josh's work as everything worked there besides the google cam... so im just using josh's rom and boot image from the first page of this tut for now.

flashing Josh1x's system image from the lineage rom, instead of a gsi, is probably the most complete option to date. only gcam doesnt work. his boot.img has to be used as well.
[LG G7 ThinQ  Guides, News, & Discussion] Aseiel:
gcam works on vendor from Carbon ROM.
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
I got as far as unlocking the bootloader on my G710ULM. When I flash the 21d KDZ, I lose fastboot so I can't go any further. Same deal with an EU KDZ. Any ideas?
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
See my previous post. You need to wipe lafa and bootb to get fastboot on 21d. For some reason when I

first made this guide I maintained fastboot in 21d so the tutorial reflects that.
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
I see, thank you, but in order to do that, won't I need Magisk to grant root adb shell access? And isn't that only possible on the 11G firmware?
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
you can do it in 21d/20e or 11g. i did it in 11g as it requires one less boot into android for root access.

so to get fastboot in 21d/20e from 11g, you have to have root on 11g. boot into android and use adb to run the following commands.

dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf_a

dd if=/dev/zero of=/dev/block/bootdevice/by-name/boot_b

Then boot to fastboot and set partition b as active.

fastboot -ab

Now restart from fastboot and hold vol up. this gets you to DL mode. use partition DL in LG UP to flash everything from 20e/21d but laf_a and boot_b. ( you can also pre flash 20e twrp to boot_a and exlude that from the partition dl as well)

to get fastboot in 21d/20e

the only way to do this is to have root in 20e/21d. so you flash the 20e boot twrp/root to boot_a while still on 11g, then reboot to DL mode and use partition DL to flash everything but boot_a from 20e/21d. then run the above adb dd commands.

Either way you get fastboot on slot a by holding vol up on boot, and DL mode on slot b (after you manually change to slot b) by holding vol up on boot. It auto switches back to slot a if you try to boot slot_b

see the link to a google drive doc in that previous post as well.
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
Thank you very much, I'll try this and get back to you :)
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
I updated the guides (since they span three posts haha) for fastboot on 20e/21d
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
Thank you :) but when I went to zero laf_ a and boot_b, i got the following warning:

[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
never seen that before. i did write the of= path off the top of my head so id double check that it is correct. (paste the commmand in, delete the 'a' off of laf_a and press tab, it should show options for auto completing the path with files that begin with laf_, so laf_a should be one of those)
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
So apparently the above error didn't matter, and I've managed to flash lineage. However, when I went to flash gapps, i noticed that i have lost fastboot, so I can't do any of the steps after that. Is there anything I can do?
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
That's really weird. If you still can boot in to Android, you can use dd to wipe. Laf a and boot b or flash any partition. You can also use the terminal in twrp to do this if you can't boot.

Or you use LG up to restart the whole process.

But at what point exactly did you loose fastboot?
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
I lost fastboot right after flashing LineageOS.

I don't think I can use DD as SU without Magisk. I need fastboot to install Magisk, right?

TWRP is also gone, doing the normal button pattern for recovery takes me to a Lineage one.

I'll try starting from scratch and seeing if that helps.
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
If your boot image has magisk, you just need the APK. Lemme think about your fastboot issue some more. I though it flashed just the system IMG, but that's not what my tutorial says :o. But you shouldn't loose fastboot after flashing lineage. It doesn't overwrite that.

Edit: im guessing that slot a was marked as unbootable for some reason so it is defaulting to slot b, which only has dl mode after wiping lafa and bootb. I would highly recommend that you extract the system IMG from the lineage zip and then flash it like a gsi (top of page 5 I believe)

If you really want to use the twrp zip, you could try flashing the magisk boot patched file from dd in twrp terminal to prevent the boot from failing.
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
Thanks, I'd like to try the method you described, but I'm not sure how. Which partition/s would I need to flash with the IMG?
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
Unzip the lineage rom, then search google for a payload bin extractor. Use that to extract the payload from the zip and get the system img. download the vendor, vbmeta, and dtbo from this post .. Follow the fastboot procedure from that post as well. the system_gsi.img is the system image from the payload bin

Im working on fixing vibration for all the gsi roms so we can use those :)
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
I installed carbon rom and its working so much better. no volte but everything else is working well.

as for the GSIs:

you can install arnovas 1.7 gcam and the LlamaMonster_G7_Pie_2.1.xml gcam config to get a working gcam on the gsi's. I was on aosp 10, but id guess they would work on other ones.

llama monster gave me this vibration zip that replaces the stock vibrate service. it didnt work on aosp 10 but may on other GSIs. extract it to your devices root after mounting /vendor readwrite. also delete /vendor/bin/immvibed

Theres probably a pretty simple led fix, i just havent bothered yet.
[LG G7 ThinQ  Guides, News, & Discussion] haru75:

Sorry for the radio silence, took a break from this since it was getting rather annoying :P

I successfully installed the Lineage 17 GSI following the instructions in post #11, after getting root on 11g first and then 20e through the steps in this guide: https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit. Thank you both very much for your help!

I installed the Carbon ROM vendor, and everything is working perfectly apart from vibration. Speaking of that, how do I install the vibration fix?
[LG G7 ThinQ  Guides, News, & Discussion] sirbow2:
That fix might work on los 16, but not los 17.... i tried.

I've been running carbon rom (pie) from llama (find it in that same drive link with the vendor). it's pretty much flawless and has excellent battery life. llama is also working on a g7 specific los17 rom which is also on that gdrive and is mostly bug free (havent tried it yet).
[LG G7 ThinQ  Guides, News, & Discussion] haru75:
Thanks for the info :)

The vibration isn't a huge issue, so I think I'll hold out til that LOS17 ROM is tested a bit :)

Okay, I get every step correct until I get to the LG UP step.

"Use the lg up linked in this post to flash 20e/21d without laf_a and boot_b with partition dl mode"

"Error:0x2000, Invalid command response code = 0x80000001"

I'm stuck here, even after ignoring this and trying to follow the rest of the steps everything just crashes and burns.

[LG G7 ThinQ  Guides, News, & Discussion] mudtub:
I had the same problem! You can enter fastboot and download mode but not boot. :confused: I'm suspicious the guide is not telling us to install the correct kdz, but I could not flash 20e after doing the 21d. So....

I did actually manage to unbrick my ULM. You need to install the version of LGUP called LGUP_Dev_Frame_Ver_1_15_0_6 and use command prompt to run

lgup_cmd.exe com8 "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "C:\users\red\Desktop\bas2\G710ULM11g_01_NAO_US_OP_1112.kdz"

(Of course that's a loose example of what you would type.)

This will get you back on 11g. The LGUP in the guide did not like flashing back to Oreo.

Going to try going through this process again in a bit and using a different kdz. Cheers!
[LG G7 ThinQ  Guides, News, & Discussion] mudtub:
So I did get it to LOS16 and then LOS17, in between 20e and opening TWRP getting into fastboot again was tricky and the fastboot menu looked weird, it had start and power off options but the other two didn't really show up so it was a guessing game to choose the one that says recovery.

After installing LOS16/17 I lose fastboot access altogether but I keep download mode. I settled on LOS17 bc it has gapps already. LOS16 opened LineageOS recovery but it was pretty useless, couldn't use the sideload ADB to put anything on (adb said the device was offline and the logs for that recovery looked like it wasn't loading properly)

LOS17 opened LineageOS recovery but it looked like CWM and after opening once I couldn't open it again.

Somebody else fixed the missing fastboot/recovery with GSI images or dmnoverity zip right?

How do I go about to un-zero the following?

This is similar to the act of deletion.

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

Edit: I had to place 'adb shell su' in front of dd if=.., AND I had to permit 'Shell' in Magisk superuser access.

According to what I saw on stackoverflow.com on re-mounting partitions with ADB, it may be the following but I'm not quite sure:

mount -o rw /dev/block/bootdevice/by-name/laf_a
mount -o rw /dev/block/bootdevice/by-name/boot_b

And just to confirm inregards to:

Only the following must have already been executed to make laf_a and boot_b are 'disabled'

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

Wipe everything may be referring to the task performed the tend of the following post.

But there is no, system.img vendor.img vbmeta.img nor dtbo.img files.

Where do I obtain them?

I found the following on reddit, on how to extract system.img

reddit.com/r/LineageOS/comments/7hue1w/how_can_i_get_systemimg_from_lineages_build/

Seems you'll need to install Python run time environment or something like that.

I have the following files:

E:\..\lineage\System.img extractor\brotli-master\

E:\...\lineage\System.img extractor\sdat2img-master\

I installed Python 3.7

Where would I go from here to extract system.img?

I installed brotli with the following:

Edit: It seems to the following, adb push LINEAGE.zip /sdcard/

I was able to successfully install brotli,

Edit: This post talks about extracting system.img, file size is 1.29 GB

How would I go about extracting vendor/vbmeta/dtbo?

Edit: This may be the vendor.img file, provided by this post, but I'd still like to know how to get it myself.

Had to do ctrl z or ctrl c to exit 'dd' command:

Same with the following as well:

adb shell su dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf_a bs=1m

Edit: I'll go ahead and use the QFIL method described here.

I used KDZ Extractor executable, and got less than ideal results.

[OnePlus 6T  Questions & Answers] gs2jb4.1.1:
From my understanding I'm in the same boat, the only fix I see in other forum's is rooting, or waiting for TMobile to put out a10. Which will probably take along time
[OnePlus 6T  Questions & Answers] Striatum_bdr:
This has been answered many times.

To be certified by Google, the ROM digital fingerprint must be communicated to Google by the manufacturer.

As you have modified your device by installing an OOS designed for another phone (yes technically global OP6t is a different phone compared to TMob one), there is a mismatch in parameters transmitted to Google leading to a non certified device.

The only solution is to root and use a Magisk module to modify your phone digital fingerprint towards a recognized one. (Magiskhide props config)

Complaints are to be addressed to TMobile.
