LG-US998 20B ROM​
Hello everyone

This Rom is 100% Stock. TWRP 3.2.1-0 must first be installed as with Nougat Roms. Then you can install this Rom and have Oreo with working TWRP.

This zip is created from the original KDZ. I changed the Boot.img, so you do not have to reinstall TWRP. . . ;)

I had made this for users who can not get ota's because they have Custom Recovery / Root installed

Sorry for my bad english i'm out of practice :p

Features​
*Stock build made from official KDZ
*Stock Build.prop
*Unrooted
*Boot.img modified to keep TWRP
*Remove dm-verity
*Remove forceencrypt​
Installation​
What you need​
*Unlocked Bootloader [How to do]
*Working TWRP installed [Link to unofficial TWRP]
*When you need Root, Latest Magisk [Download]
*US99820B(TWRP).zip [Download]
*GDrive Mirror US99820B(TWRP)[Download]



How to install​
When you are on Nougat: Reboot to recovery using button combo or reboot app (need root)
flash this TWRP.img Download reboot and Backup Dalvik,ART, Cache, System & Data (include not your internal memory) and Boot
in to your external sd or copy the backup from internal sd to your PC!
From Oreo: Install TWRP with this guide but with this img
For clean install: Wipe Dalvik/ART, Cache, System and Data (Recommend)
You can also keep your data by dirty flashing the zip. *Not tested!!!*
Flash US99820B(TWRP).zip
then Magisk zip when you need root
Reboot System


At the first time you boot to system, it can be TWRP says No OS installed. You can ignore it.
If TWRP asks if you want to install SU, hit no



Here you can find my other [Downloads.] There are IMG´s, KDZ´z and more!

I've been using Textra on 3 phones now. I had to change the setting in Textra MMS settings to "Legacy" and manually configure some of the APN settings. The MMSC automagically was correct and just edited the MMS proxy port to 80.

It seems there is something wrong with the Bluetooth on this stock ROM. I have a Fitbit and it hasn't been syncing the whole day. So I turned it off and then on, still didn't work. Then rebooted the phone, still nothing. I had to reset Bluetooth settings in order for it to work. A few hours later it stopped working again. Do we have e to reset settings all the time for Bluetooth to work? Or is this just a bug in this ROM?

Trying this on my US998, previously running the H930 Oreo Stock rom, it boots up into a "Secure start-up" screen, saying "Decryption unsuccessful", then says I need to perform a factory reset (and has a "Reset Phone" button). This won't touch my internal sd card, right? I did a full wipe (minus internal sd card of course) beforehand.

Factory reset will erase everything on the 64/128 GB drive except for the OS.


Did you wipe internal storage in TWRP, did you flash the no encryption file and the no check root file? The reason you're getting that message is you didn't do one or both of those in TWRP.

I flashed both of those when I first got my phone, several months ago. First thing I did was that and then install this rom, which I've been running fine ever since, but I'd like to switch to the actual US998 ROM since that's what I have.

So even though I've been running other Oreo roms just fine I still need to wipe internal storage? I just tried flashing lg-rctd-disabler-1.0.zip and no-verity-opt-encrypt-6.0.zip after doing this rom, but got the same thing about decryption unsuccessful.

Yeah, because you're flashing back to stock firmware. The only difference is it's a TWRP flashable zipped file, so you can install via TWRP. But it's not really a "ROM".

Well, I went ahead and wiped internal storage (after backing up important stuff to my external sd card), wiped & flashed the zip, plus two I mentioned before, but it did the same Decryption unsuccessful screen again. I went ahead and tapped the reset phone button (after removing my external;), it booted into TWRP, I rebooted into system and it went to the Decryption unsuccessful screen again.

In TWRP you have to reformat data where you type yes.

Just wiping it leaves encryption.

Textra on VZW US998

I've been using Textra on 3 phones now. I had to change the setting in Textra MMS settings to "Legacy" and manually configure some of the APN settings. The MMSC automagically was correct and just edited the MMS proxy port to 80.
Finally, Legacy and the MMSC setting was the trick to gifs showing up sent to me instead of showing as just a picture. Now if only voicemail would show up in notifications up top instead of getting a VZW random nonsense text letting me know i have a voicemail. I tell ya, VZW are a bunch of dicks, pulling this kind of **** for running an unlocked phone on their network and all these hoops we have to jump through to get **** to work and still some of it not working right...(voicemail for example). Thanks again. Running US998 20b stock flashed TWRP version. Magisk 16.0 and Adaway installed.

    Magisk version? With 16.6 beta there are many problems on my h930

    I'm using v16.0. It flashed fine through TWRP after I rebooted the system. :good:
    I was upgrading from US99820a to 20b. I haven't had any other issues to report.
