I'm not getting traction in other threads, but could use some help so I made a new thread for visibility.
Long story short is I rooted my us998 V30 and everything seemed well, but ran into some app issues so I needed to reload my backup to correct them. Again, seemed to go okay. ...but ever since I've run into small issues like "system isn't RW" and "structure needs cleaning" as well as some apps not working properly. I even tried installing the custom WETA rom only to be fooled into thinking it worked, but couldn't find anything "WETA" about my phone once it booted again.
Anyway... what I want is to nuke this and start from scratch, so... how can I restore my phone to full factory install so I can begin again?
I've downloaded the US99810c_03_1216.kdz
... but I'm not sure what to do with it. I seemingly need LGUP or LG Flash tool, but can't seem to find the latest downloads for either and when I google them most places seem like virus ridden locals that I should avoid.
Once the phone is restored.... I should be able to follow the rooting guide again (hopefully without the structure needs cleaning issue)
Thanks for any help... online right now and looking to get this sorted over the next hour... really appreciate any help.

The download links posted in post #1 of this thread seem to work.
That post also has instructions on how to use those tools. There's three different options. You had read some of the most recent comments to see what people did.

Took a bit, but ran through it... was able to load the KDZ using uppercut... refused to let me refurbish though... thoughts??

Not sure why it would not work for you, but options 2 and 3 don't use Uppercut. Try those?
@padmanek, any ideas?

I can do "upgrade" just fine. I'll try a factory restore and see if refurbish works after that.
edit, didn't help... can't "refurbish" but can still "upgrade".

I'm not sure, it appears to reinstall the ROM... but all my installed apps and software were intact. (well, until I factory reset anyway, lol)
Either way it seems to have corrected my issues with "System isn't RW" and "structure needs cleaning" as I was finally able to cleanly "re-root" per the guide here:
https://forum.xda-developers.com/lg-v30/help/unlocking-rooting-twrp-magisk-step-step-t3745006
Now... How do I properly install WETA? lol
Hey there guys, so I did as I'm sure many of you do out of habit and checked for an update this morning. Low and behold with zero announcement Oreo is here!!! I couldn't be happier, but am I the only one who noticed it's dated for April 24th?? What're your guys thoughts on that? Did lg hold out on us, or maybe the carrier?
So this is Christmas...

If you have PC access you can go ahead and grab the kdz and flash it with lgup. So long as you're sure your phone is an h873

It shouldn't but backup just in case
It's always better to do a factory reset after a change in Android version, eg. 7.0 to 8.0, so would recommend back up now.. When you change to Oreo, reset afterwards., then restore.

The KDZ will work regardless of your carrier, so long as your device is an H873.
I flashed it on my Koodo H873 last night and it works perfectly. Just be sure to check off upgrade in LGUP so you don't lose any of your data. Open LGUP using Uppercut.
As long as you don't unplug your phone during the upgrade, you will not brick.

Of course!
Assuming you've downloaded the KDZ, the only other steps are getting LGUP and Uppercut. Just google them, you should be able to find them.
Install LGUP (Make sure it is version 1.14) and run Uppercut. It may trigger a virus warning, so you should disable your antivirus temporarily. It is not a virus.
Plug your USB cable into your computer WITHOUT the phone plugged in.
Shut off your device and plug it in while holding the volume up button. It will enter download mode.
Finally, in the LGUP interface, it should show your device model on Standby. Check off "Upgrade" if you do not want to lose your data, or "Refurbish" if you want to factory reset it. In the list at the bottom, select "BIN" and click on the three dot button. It will prompt you to choose your KDZ.
Assuming you did everything right, click on Start. DO NOT TOUCH YOUR PHONE WHILE IT IS UPDATING. When the progress bar in LGUP reaches 100% and your phone enters the "Android is Upgrading" screen, you may unplug your device and wait for it to boot.
Voila, you have Oreo! Please PM me if anything goes wrong.
In the future, please look for an existing thread for flashing instructions. I will make an exception here because you are new to flashing, and I know it is confusing.
Nothing to see here. *jedi wave* Move along.

What US998 firmware are you trying to flash? Why aren't you asking this question in the Frankenstein thread? Did you even read those instructions?
What do you mean "when the process was done"? There's four or five steps where you flash TWO different US998 firmware, with Master Reset in between. How far did you get?

2. Sorry it's like my first time on this website, i didn't know such a thing existed.
3. No, I am sorry I didn't know there was set instructions
4. I mean when the program was done flashing the KDZ the first time
5. I had just put my phone in download mode and flashed the US99810d_01_0411.kdz then this problem arose right after.

Also, after you go back to US998 Nougat with Refurbish, then do the Master Reset, and when you refurbish back to Oreo go ahead and go to 20H KDZ.
Your bootloader should still be unlocked, I would think. (However, if you don't see the bootloader unlock warning after Nougat and Master Reset, then go to 20b)
From 20H, then you can reinstall TWRP, and flash the three root files again (no encryption, root check disable, and Magisk).

I am still just restarting a couple of seconds after getting to lock screen. It kind of looks like the phone doesn't actually complete the reset it goes the deleting screen for about 2 seconds before rebooting.

I don't see that you first flashed Nougat, then did Master Reset before going to Oreo.
Nougat would be 10c or 10d (your choice).
Oreo starts in the 20's.
Frankenstein Instructions say to flash Nougat, then Master Reset, then go to Oreo. There's a reason for each step I don't have time to explain here.
Something about your phone is messed up and doing Frankenstein over (Nougat, Master Reset, then Oreo) should fix it.

It DOES work if you flashed the right firmware.
If you have a constant bootloop and Master Reset doesn't fix it, it means you usually have flashed the wrong firmware.
I'm betting that you tried to flash Oreo first instead of Nougat.
What letter/number US998 Nougat did you flash? Did you use Partition DL mode?
Please read Frankenstein Instructions again. You should be asking in that thread if you are trying to convert one North American variant to another.

If you already have US998 V30+, why are you flashing US998 Nougat? What are you trying to achieve?
You don't need that for bootloader unlock -- you need early Oreo 20a or 20b. The only reason to flash Nougat are for North American variants who have to convert to US998, before flashing US998 Oreo 20a or 20b. Most can't flash directly to Oreo 20a/20b, they have to first flash Nougat, and do Master Reset, then flash early Oreo.
Were you using Partition DL or Refurbish? Read the Master Reset directions again.

If you press the buttons long enough, hopefully it will reboot.
Still didn't answer why you were flashing Nougat, when you already had USS98 firmware? You only needed to flash USS98 20b.
I'm afraid you unneccessarily flashed it because you didn't read instructions carefully, so I don't know what else you didn't read carefully...
Hope you get it working again!
