After flashing twrp in fastboot, did you boot directly into recovery or did you boot back into Android first? If you boot into Android first it will overwrite recovery with stock again. Correct steps should be:

Reboot to bootloader

Flash twrp

Select power off

Do key combination to boot to recovery

Boot to Android from twrp
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] topolovich:
Thanks for the info! 0I tried to go directly into TWRP but. I probably missed it and let the recovery get written over and didn't think twice about it. That's the first time that ever happened to me and I've been nervous to try it again.

What you said makes sense though so I'll give it another try... I will flash it and then boot directly into it with fastboot just to be as safe as possible..

Thanks again!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
OTHER OPTIONS:

No need to do the button dance. While still in fastboot mode, you can boot to recovery apparently, even that first time after flashing it:

NOTE: you don't have to type all this out, even when flashing or for that reboot command: "TWRP-3.2.1-joan-v0.1.img". It will just look for the file name you designate. Just call it "TWRP" . You can re-name the file to "chair" if you wish, i.e., "fastboot boot chair.img" or "fastboot boot TWRP.img" -- whatever you re-name it in your folder before you flash.

Unfortunately the comments are mentioned early on in this thread, so without assuming I went ahead and started with relocking my bootloader. Now I'm stuck at the same issue saying "Your device has failed a routine safety check..." and cannot access bootloader or anything else, basically my phone is bricked I believe.

Any idea on how to fix this??

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Shelltoes:
What just worked for me was powering on and holding the volume up button until I went into downloader mode. From there I used LGUP and was able to flash the .kdz. Phone restarted to the Welcome screen so it looks like it took (Phew!). Just re-unlocked it and starting to add joan TWRP and root.

Will let you know if there's any other issues but seems to be okay now.

Having some troubles.

Flashed this update and since then it will not provision or recognize my MDN correctly. I have tried resetting it, reprogramming it, etc, and it doesnt stay my actual phone number.

The first time it also seemed stuck on the idea that I needed a tmobile sim, but after a second reflash that has gone away but I still cant get connectivity.

Also, my dialer will not recognize codes,instead it just blanks out instead of opening the correct screen.

Anyone else run into the same issues?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Dirty flash or clean flash? T-Mobile, what?

Try wiping and re-flashing.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JonnyTrulove:
Dirty flash, Sprint.

Things went really sideways for a minute. Tried to revert back to a twrp backup, locked out by my own pattern, deleted pattern lock file to get back in. Tried again, Full Wiped, reflashed, lost OS due to a system mount error i somehow missed, only had access to fastboot.

Got twrp back up and running, new wipe, and flashed the new file again but still wont. Provision correctly.

Was i wrong in thinking i read other's flashed this and had it working on sprint?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] kventura:
do you use both quad dac and DTS at the same time?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Yes, of course. I have 64ohm E80C earbuds and High Impedance Mode is great, but the DTS takes it to another level.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] gimpy1:
Where i could really tell the difference was when I was using my blue tooth iems. (I think I have a pretty nice sounding pair (flares pro) - I know it does not use the quad dac). When I connected my 50 ohm headphones (which does activate the quad dac settings) , and turned on both the dts and quad DAC settings, then I could not tell a difference switching the dts settings.

That was just a quick experimentation I did yesterday.

May I flash this in my h930ds ???? Twrp version is not useable.I can change the modem
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
No, you cannot cross flash H930DS with any North American variant firmware. You are going to have to wait until H930DS or perhaps European HD930 receives the DTS libs. It should be coming to all phones. I do not know why the US998 was the first.

The TWRP flashable zip version is the same as the KDZ, just in format able to be flashed with TWRP (and root checker and encryption already disabled). Both are just stock firmware.

This was my answer to you in the ZIP thread and remains the same:
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Works on T-mobile, Verizon, AT&T for sure. ;)

This KDZ should work on Sprint also (has lots of Sprint references in the firmware!) -- except for the two Sprint LTE bands the US998 doesn't have. You would need to make sure you have Sprint APN entered. [MENTION=6815443]JohnFawkes[/MENTION] can tell you more; he has Sprint but he uses his own Sprint ROM. He's also going to soon release a hybrid ROM, based on this but with Sprint stuff -- if I understood correctly.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
Yes sprint will work. The only issue I have while being on us998 firmware is I lose VoWifi and VoLTE and I can't get lte data. I only get 3g and 1x. With my hybrid rom I get all the bands. Even the 2 missing ones. And full lte. Another upside is dts of course :good: but what I've found is the sprint references differ between us998 and ls998 firmwares [MENTION=3250376]ChazzMatt[/MENTION]. They are very different. So what I've done is remove all the sprint stuff in us firmware, run a diff between the 2 firmwares and then copy anything over that us needs for sprint and patch any files (like permissions xmls for sprint apps) and then build the rom the same way i do the kdz zips. I have just a few more bugs to work out and it will be ready for release. After I release I'll be looking into doing the other carriers as well. Maybe combine it into an aroma install or something eventually
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] deroth:
My phone is still on 20a (unlocked, t-mobile). After reading through this thread a bit it seems that it's safe to dirty flash the latest TWRP version, am I correct?

Edit: is this firmware/ROM fully compatible with the US unlocked 998? Reason I'm asking is months ago I tried a 930H-based custom ROM (which is from what I understand this one is based off) and lost WiFI calling and VoIP on T-Mobile.

Thanks!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Yes, safe to flash the TWRP-FLASHABLE version. It's just stock KDZ firmware in a "ROM" wrapper, so your can flash via TWRP. Be sure to reflash Magisk before rebooting.

You should also wipe the caches. ;)

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Where it always is, post #1. All the KDZ and TWRP flashable zip download links are there, beneath their respective file names. They even say DOWNLOAD LINKS. Listed most recent to oldest, top to bottom. You can't miss them.

Having said that, I do see the 1st AFH 20F download link for some reason sent you to my AFH profile... BUT on that page, the 20F download link was STILL there, listed under my profile. The other two 20F links (LG-Firmwares, TWRP flashable) were to direct downloads. The 20F AFH link has now been changed to be direct download page. But all the download links ARE there -- so I don't know if you are not seeing understanding what a hyperlink is or you were questioning the inadvertent 2-stage AFH download link.

GM shuvo, almost all developers and posters keep all updates and links in the OP (very first post of the thread). So, you should always read the very first post very carefully. That is "usually" where you find everything you need (download links, instructions, etc.).

On real long threads, 100's of pages, I like to read at least the first 10 or 20 or so and also the last 10 or 20 pages to kind of catch up on things, somewhat.

Post #1 now updated: US998 US99820g_01_0110 full KDZ and TWRP-flashable versions of KDZ. January 2019 security update.

Additionally, the US998 20G TWRP-flashable version already has the

build prop edits to fully enable DTS 3D stereo

, thanks to [MENTION=6815443]JohnFawkes[/MENTION].

Right now this full DTS capability is only available on US998 firmware 20F and 20G, by these methods:

*

do it yourself

,

*

flash this Magisk module

(which also does other cool stuff),

* use 20G TWRP-flashable zip.

But [MENTION=6815443]JohnFawkes[/MENTION] is building/testing a hybrid stock ROM for other variants with the DTS 3D Stereo framework. Stay tuned.

LG should also release this DTS 3D STEREO framework to other V30 variants in future updates, hopefully very soon. Also, hope they fix the issue where you need to root the phone to fully enable this awesome feature!

Dirty flashed over F. Cleared cache and ART. Flashed ROM. Flashed Magisk. Flashed Xposed. Rebooted. Ate pancakes. Audio is fine, as is everything else. If you still can't get it to work, this is a LAST resort. Make sure both the ROM and Magisk zips are on your phone, IDEALLY on the external SD card. Have your data and apps backed up, either using Titanium Backup or Google Play, at the least. In fact, and I always advise this because I'm a psychotic computer tech of 18 years, backup EVERYTHING. Boot to TWRP. Go to wipe and advanced wipe. Wipe data, system, cache and ART. IMMEDIATELY flash the ROM zip. Do not reboot! Flash Magisk. If you get ANY error, flash Magisk again. It should take. Reboot phone. Everything is wiped, so run the setup and restore your data however you choose. Try other solutions first. As I said. Last resort.
