Hopefully this is the right thread for troubleshooting for my v30 that's boot looping, below is a list of what I have done,
I followed the WTF guide by ChazzMatt Frankenstein Method since mine is a H933 variant ,
LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions)
(WTF...!) LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions) WTF...! LG V30,V30+,V30S (MOST VARIANTS) BOOTLOADER UNLOCK, TWRP, ROOT INSTRUCTIONS HERE >>>CLICK HERE TO POST #193
forum.xda-developers.com
After that was all said and good I attempted to install LineageOS with no success, eventually I read that I needed Pie again for it to work, so I grabbed a Zip from here
How to Install Android Pie Update on LG V30/V30+/V30S (All Variants)
Through this post, you can download and install Android Pie update on LG V30, LG V30+, and LG V30S. This could be done easily by flashing the Android Pie KDZ or TWRP-flashable zip. Back in 2018…
www.thecustomdroid.com
After that I accidently hit reboot instead of installing the other zips that were required in that guide, and now my V30 is stuck bootlooping, V30 Download Mode doesn't work and stays in server and PC mode then reboots itself, and I can't seem to get back into TWRP, I have done the Dance and Factory reset but that did not work either.
Any and all help would be appreciated, I can get Linux installed on another computer if required.

I am from HK, forgive my bad english please...
I just buy a UK version v30 (H930)
I have a few question about:
1) I hope to use android 8.0. can I upgrade the phone to last version of H930? my phone version now is 7.1.2 V10v-EUR-XX
2) I found some reply in https://forum.xda-developers.com/lg-v30/help/unlocking-rooting-twrp-magisk-step-step-t3745006 seems telling me that after rooted, I can't reboot the phone, otherwise the TWRP will lose, that means lost root? and I need to install TWRP and Root again every time.
3) after upgrade to android 8.0, can I just follow https://forum.xda-developers.com/lg-v30/help/unlocking-rooting-twrp-magisk-step-step-t3745006 #1 to root?
thanks for read & help!!!
Your question is simply a TWRP question.
After installing TWRP custom recovery, you have to then immediately boot to TWRP and enable it. If you boot back to regular OS first, TWRP doesn't stick. That's all that warning means.
Once in TWRP that's when you flash the root method of your choice, Magisk or SuperSu.
See this post for bootloader unlock, TWRP, root. You already have H930 so you're already one step ahead:

Yes that's the one you use for H930 with that attached LGUP to upgrade to Oreo.
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...
The main problem here is failing to boot to fastboot, with both adb and button way failing.
Any idea? A korean ****up?

Korean V30 variants don't have the necessary fastboot flash commands. Only H930, H939DS, and US998 have those.
That's why for WTF bootloader unlock and root method Korean variants have to temporarily convert to EU H930 (but they lose radio bands), and then flash back to something else with TWRP flashable zips after bootloader unlock and root, to get radio bands back.
These Pie betas are just inferior partial OTA files. Once full KDZ is released, you'll probably be able to root by using WTF/Korea variant method again. As long as you keep unlocked bootloader!
Is it possible to get H930 Recovery backup via LGUP？
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)
IMPORTANT: NEVER ERASE THE ENTIRE FLASH (IT WILL BRICK YOUR PHONE **STILL CAN BE RECOVERED**) IMPORTANT: FOLLOW ALL THE STEPS IN ORDER TO UNLOCK BOOTLOADER SUCCSSEFULLY; DISCLAIMER: I AM NOT RESPONSIBLE IF YOUR PHONE BRICKS! YOU ARE FOLLOWING...
forum.xda-developers.com
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?
Which version of twrp would you use for Android 9 and above?
I would probably install the latest. I just posted it here:
