Can I upgrade from rooted 10d with this? Or do I have to update to 10i first, then 10j? Also what settings to choose in LG bridge?
If your using the image posted you can use LGUP, if your using LG Bridge it will download the image for you.
You need to be on a stock ROM I believe, I flashed the stock odexed rom. You can try it on a custom ROM though and see what happens.

If you want to use LGUP then you can download the above images.

What about stock recovery? Is that needed? If so how do I flash that?

my upgrade steps were as follows:
backup anything you might need from the internal memory - /sdcard
backup anything you might need with TiBackup (just in case)
boot into TWRP and make a backup of /data
update to 10j via LG Bridge or LGUP (you will be returned to stock after this)
boot up and follow @jcadduono's post on rooting H91810d with recowvery
his detailed guide will leave you in TWRP with a freshly formatted and unencrypted /data
restore backup of /data in TWRP
done. profit.

NOTE: crucial you backup your /data in TWRP prior to updating because after updating your /data partition will be encrypted and you will no longer have root. once your /data partition is encrypted TWRP won't be able to see it. I believe you can still root with an encrypted /data where you'll then be able to use TiBackup to backup your data, but this method would be a slow restore versus restoring via TWRP.

Can anyone extract the ing files and make them flashable so we can update through twrp? My hard drive went out last week so I can't update and keep root without doing it through twrp.

any idea how to make img files flashable?
You just need to build the file tree and make a script to tell them where to go, I believe.

Or we could at the least flash a 10j based rom and then install the system img over it. Just need the extracted imgs from the kdz that way.

Um so after updating no more TWRP and still can root bit confused here?
updating and rebooting will revert you back to stock... you'll need to redo the steps for recowvery to install TWRP and root again... you'll also need to backup your device as you'll need to wipe /data to unencrypt

Can I just take the OTA to 10j and wont cause any bootloops? then just re-root?

I've ran the commands manually and I get confused about the .xml copy being put into local_manifests. I made the directory in my C: drive but Its a windows not linux computer I have access to. Does that matter?
So I get to the manual inputting part, right... And prompt says can not find file
at the first manual input of dirty cows command prompt

Just wanted to thank you, because you're a lifesaver. I bricked my phone (unfixable TWRP loop), and I tried downloading the KDZ several times from LG-firmwares, but it was extremely slow and always ended up failing. Then I found your Drive link, and approximately 9 hours after bricking the damn thing, I was finally able to fix it. Learned my lesson, too. I'll never again mess around with a new phone BEFORE acquiring any and all recovery tools, especially from a new manufacturer (I'm used to HTC).

Hi guys, in need of your help. I was originally on H91810D rooted and decided to try and install the OTA update not knowing that I would get stuck in a TWRP loop. I've downloaded H91810j KDZ file along with both LGUP and LG Bridge to try and flash the KDZ onto my phone, but neither UP or Bridge detects my phone connected to the PC, but Windows 10 detects that my phone is connected. I'm stuck sitting in TWRP and no matter what I try, it won't work. Any suggestions on what I can do to get through this? Any help is appreciated. Thank you!
