I have an ongoing issue with this phone, I want to install TWRP and eventually a custom ROM on my Canadian LG G7 ThinQ LM-G710AWM.
I have been able to root by patching boot_a and boot_b with majisk and using QFIL to modify/write to the partitions.
I was also able to unlock the bootloader by following this post:
[GUIDE] Guide to unlock bootloader for every LG SDM845 except G710TM (With PHOTOS)

After deleting both the lafs in QFIL to get fastboot back, I tried flashing several TWRP images which are recommended for my model, and i get an error [fastboot:error "cannot get boot partition size"]
I've tried flashing it to boot_a,
I've tried flashing it to boot_b,
I've tried fastboot boot "TWRP IMAGE" to boot into TWRP temporarily but it shows 'download mode' for about 10 seconds and then reboots normally
I initially crossflashed then refurbished from Android 9 Pie to Android 8 Oreo, using LM-G710AWM, basically a downgrade, for reasons, and still Ive hit a solid wall with this.
Any help would be greatly appreciated, there seems to be no way to get into TWRP.
Still with that problem?

Using h830 device running stock as primary and encountering an error when flashing patched zip for tmobile. It says that my device is h1 and that it can not complete the flashing. It fails in twrp altogether. I tried patching with the h850 variant selected and it fails in tarp but passes in the app. After reboot from application flashing I get stuck in a twrp loop and have to flash the stock image over again to restore my device. Any thoughts?
Hi,
I have a rooted LG G5 H850 with an unlocked bootloader and TWRP. I was on H850 20A OPEN EU ROM from autoprime and I tried to flash H850 20D OPEN EU ROM. I booted into recovery TWRP and flashed the Zip file together with the newest SuperSU. When I tried to reboot the phone stuck in reboot - always changing between the message "Your device software cannot be checked for corruption" and the LG logo. After a long time (15 minutes or so) I pulled the battery. The same thing. Then I tried to get into recovery using the 2 hands method. I clicked through the factory reset screens (yes, yes...) - and the phone stuck between warning screen and logo again.
Could someone help me to get into TWRP again? If this would be possible I could restore my backup. Otherwise I don't what to to else...
Thanks for any helP!
Ok, after several tries with the 2 hand method, I got into TWRP again. I tried to restore my backup but it failed with an error. After that I did a full wipe (factory reset) but without the internal storage. Then I flashed the 20D zip again, after that SuperSU. Now the phone is rebooting and rebooting and rebooting. It is stuck on the LG logo and nothing else is happening. It's frustrating...
Firmware reset > flash zip file.
If that doesn't work use the LGUP or LG Bridge method to flash firmware. There should be threads in the development section

Thanks for your help, but I don't use windows. But in the meantime I got it solved. The reason for the failure was a corrupted external sd card. Flashing from a new card did help.
i'm getting the same problem with the OREO OPEN EU ROM, booted into TWRP, flashed SuperSU and after a few loops got stuck on the LG logo. Had to pull the battery, go into download mode & reflash the ROM via LGUP. I somehow doubt it's the SD card as there were no errors on the SuperSU install.
Hello all,
I have a Verizon LG V30 that I converted to a US998 LG V30 using the Frankenstein method. Today, I clicked the Uninstall option in Magisk Manager and the device uninstalled it and rebooted. Upon rebooting, I was thrown into Fastboot mode with no way to get out (No Recovery, nothing.) I tried resetting through Fastboot to no avail. It still connects with Fastboot but nothing else. I can flash firmware with the patched LGUP but no file I have tried has worked. Is there anyway I can flash my V30 back to Stock VS996? Thank you.

Why isn't there a way to get into Recovery? Use the same fastboot commands you got into recovery the first time you installed TWRP. You can even use those commands to boot to TWRP on your phone even when TWRP is not installed on your phone, via "temp" TWRP.
Since you uninstalled root, you can't use the Reboot Recovery app anymore -- as that requires root access -- but you can still use the fastboot flash commands.

Yes, go into Download mode manually and use dev patched LGUP to flash VS996 Oreo KDZ with DL Partition method. Flash all partitions. Not sure why you are doing that however. You decided you don't want to own your phone anymore?
People who want to KEEP root and TWRP and go back to VS998 would use DL Partition method -- but UNtick the partition recovery partitions. Then you would still have VS996 but with TWRP. You would no longer have fastboot flash commands, but you would still have TWRP custom recovery. Then you just flash Magisk root. So you would have VS998 with TWRP and root.
And at that point you could even use the reboot recovery app with root to always easily get to TWRP.

Thank you very much. I am booting up my ADB and Fastboot to flash TWRP, as I still at least have an unlocked boot loader. I’ll download a Oreo KDZ for the Verizon Variant if that doesn’t work out. Do you have any sources for one on the forums? Thank you!
EDIT: Once I get into recovery, should I flash a stock ROM? There are a few on the ROMs section of the forums but I do not non which one to download.

1) Do your want to keep TWRP and root and just flash back to VS996 (while keeping TWRP and root)?
2) Or do you want to just keep TWRP but you don't want root right now?
If #1, once in TWRP, reflash Magisk.
Then reboot, and go into manual download mode BEFORE opening the patched LGUP. Then Frankenstein back to VS996 with DL PARTITION method, but untick (uncheck) the recovery partitions. Then you'll be back to VS996, but still have TWRP and be rooted.

Don't mind my other comment, I fixed what was going on there for the most part. I have tried 2 different firmware files and both of them will not boot. The Official LG Boot image (flashable with TWRP) flashed with no errors, but i just booted into download mode again. I also flashed LineageOS and the same thing happened. I tried the Refurbish and Upgrade option through LGUP and both stopped at 19% with error 0x2000. Do you have any suggestions? Thank you.

Same thing happened to mine I found no fix other then to lie to both Sprint and LG till LG agreed to take it in and fix it...
I might have done something stupid, would really appreciate it if you folks can help me get back to US998 Oreo.
I installed VS99630c (Pie) on my phone, via TWRP. After this the bootloader warning disappeared, so I suspect my bootloader has been re-locked. I can’t access TWRP anymore, neither from factory reset, nor from ADB commands on PC (the phone just reboots normally). I can’t get to fastboot either. However I can access Download Mode.
How should I proceed?

No, your bootloader is not re-locked. The Verizon firmware does not have a bootloader unlock warning. Verizon never thought they would need one...
You don't have fastboot flash commands on Verizon firmware. That's why you needed to temporarily convert to US998 to bootloader unlock and install TWRP.
To boot to TWRP, have you tried to use the Reboot Recovery app I STRONGLY RECOMMEND in all the Pie KDZ threads? Or boot to TWRP from Magisk Manager? If you have TWRP, either work unless you've wiped out TWRP.

When I tap the Recovery Reboot app the "No root detected!" box pops up. Seems like Magisk didn't install when I flashed VS99630c either.

Did you flash Magisk before rebooting?
Do you have Magisk Manager app in your app drawer? You can reboot to TWRP Recovery from there. Open Magisk Manager, go to Modules, then three dot Menu.

No, I guess Magisk didn’t flash. Downloaded the Magisk Manager app and it says “Magisk is not installed”. Should I click on install? I figure that may be risky because I’m not sure I have TWRP.

At this point in time you need Magisk installed. You can only install in TWRP.
At this point in time, you have two options:
1) try the "hardware button dance" again to see if you can boot to TWRP. If you get to TWRP, flash newest Magisk.
If you can't do that, you will have to:
2) use Dev Patched LGUP via Refurbish mode to flash back to US998 Oreo KDZ, to get back fastboot flash commands. Your bootloader is still unlocked. BEST to flash back to US998 Nougat via Partition DL, Master Reset, then US998 Oreo. Since your Bootloader is already unlocked, you can go to US998 20h after Nougat.
Then, go through WTF Section 6 instructions completely to re-install TWRP and the three root files. Do not skip any steps of that section.
Finally, re-flash VS996 TWRP 30c flashable zip and this time flash Magisk before rebooting.

After failing to boot to TWRP, I've been attempting the LGUP route but no matter what I try it doesn't recognize the device (it says "There is no handset connected"). Here's what I've done exactly:
Deleted old LGUP from Program Files
Followed all the instructions here in the section "HOW TO INSTALL DEV PATCHED LGUP": https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-vs99630a000704arb00-kdz-t3952254
Didn't work so tried again (different USB ports, used a different computer, reinstalled drivers, reinstalled LGUP, used different cable, even used different Dev Patched LGUP, etc).
LGUP recognizes my device just fine when it's booted normally, but in Download Mode there's no connection
After trying all kinds of stuff for the past few days I was just about ready to throw in the towel. Must have gone through a hundred threads on this forum.. finally I came across someone with a similar problem who fixed it with his Windows 7 PC. Found my old laptop that’s over a decade old and booted it up. Installed the drivers, LGUP, etc. Booted up my phone in Download Mode.. still no connection. Reinserted usb cable.. and the damn thing finally showed up. That ancient behemoth of a computer managed to save my phone
Thanks a bunch for helping me out Chazz

Same here. Can't access fastboot, and the patched lgup doesn't says "no handset connected."
It's as if bootloader mode and recovery have become the same thing.
Hi,
Firstly, sorry for the lack of references in my post, as this is my first one, I'm not allowed to add URLs.
I recently purchased a Blackview BV9500 Plus and I have been trying to flash TWRP, I wanted to try different custom ROMs since the stock ROM for BV9500 PLus is apparently no longer updated (info comes from a Blackview forum).
The TWRP version that I'm trying to flash is 3.3.1 for BV9500 Plus (unofficial).
I have tried different ways, using fastboot flash recovery, using SPFlashTool and flash directly the recovery file, and it looks like the flashing succeeded but I have never been able to boot into TWRP. When I turn on the phone pression the Volume UP key, I see the Blackview logo (which sometimes appears color inverted black <-> white) and then nothing happens, it goes back to rebooting until I let go of the Volum UP key, then it starts normally. I even tried with a different TWRP version (3.2.3 for Android 9.0 Pie MT6771, unofficial) with same results ...
I unlocked the bootloader (ticked it in the phone settings) and did a fastboot flashing unlock, I tried rooted (with last version of Magisk with which I patched the boot.img and flashed), not rooted ... with no luck ... (I even lost my IMEI after a complete format with SPFlash along with the googlekey, fortunately I was able to reflash everything thanks to BV support :laugh::victory
Many thanks in advance for your help, I have been trying to figure this all out for a few days now ...
Best regards.
