[LG V30 Questions & Answers] Andrew Hidd:
I have been watching your video, problem is at 1.25. When you have finished flashing TWRP DON'T EXIT FASTBOOT MODE. Do not Choose Restart or Power Off and do the following :

1 - Kill the adb daemon

p@pc:~/Android/Sdk/platform-tools$ ./adb kill-server

2 - Restart the daemon

p@pc:~/Android/Sdk/platform-tools$ ./adb devices

List of devices attached

* daemon not running; starting now at tcp:5037

* daemon started successfully

3 - Check the device

p@pc:~/Android/Sdk/platform-tools$ ./adb devices

List of devices attached

(you see nothing but it's ok)

4 - Boot into TWRP

p@pc:~/Android/Sdk/platform-tools$ sudo ./fastboot boot twrp-3.1.1-0.img

[sudo] Mot de passe de p*:

downloading 'boot.img'...

OKAY [ 0.716s]

booting...

OKAY [ 0.020s]

finished. total time: 0.736s

You normally boot into TWRP. I do not have time to do a video yet, but let me know if that worked for you.
[LG V30 Questions & Answers] tt-bert:
Thank you for the hint. But sadly killing the adb deamon didn't change anything either. Exactly the same thing happens with or without killing adb bevor typing "fastboot boot twrp-3.1.1-0-h930.img"

or "fastboot boot recovery.img" (depending on my files name).

Every time the warning screen flashes shortly, beeing followed by the normal reboot of the phone.
[LG V30 Questions & Answers] Andrew Hidd:
Mmhh this is so curious :confused:

I own a h930g maybe there is some slightly differences with yours?

Anyway, Do you have the possibility to run the same commands on a Linux PC ? You are using Win and I didn't try on such OS. If you don't have a Linux try to install a VirtualBox or VMWare. I had to install a WINXP virtualbox machine to be able to upgrade my phone to V11m (from V10f).

FYI i use a Ubuntu 16.04 LTS. Give a try on that OS and let me know.
[LG V30 Questions & Answers] tt-bert:
I'm running V11m and not the original V10f anymore. Might that be the problem?

I don't know if I can install a Ubuntu partition anywhere here, I'll try that later.

I'm also gonna do another short video of me trying to boot TWRP just via ADB/Fastboot commands. Maybe I'm still missing something.

What I really don't get is when I try to do the factory reset, it doesn't do anything at that moment but reboot the phone regularly. But once I try to acces TWRP via "adb reboot recovery", than the erasing process starts without me ever beeing able to access the recovery?
[LG V30 Questions & Answers] ChazzMatt:
Ah, that is the problem I think? Many H930 users say they have to downgrade back to 10f to get TWRP to work. It talks about that in the TWRP thread. See here:

I have US998 and I had problems getting it to stick even on 10c, but finally got it.
[LG V30 Questions & Answers] tt-bert:
Oooh. Thanks :)

So how do I do that. Never had an LG phone bevor, only Samsung und Sony. Could you please link me the respective thread?
[LG V30 Questions & Answers] ChazzMatt:
Two different ways. These are both from the V30 TWRP thread:

LG UPPPERCUT

LG BRIDGE

When the TWRP dev [MENTION=5672995]jcadduono[/MENTION], updates TWRP, this may no longer be necessary for the European H930. It's still classified as "alpha", and works but there's lot of improvements that can be made -- like changing the file properties so the phone doesn't identify as H930 when plugged into PC if you have a US998. ;) As well as not needing to downgrade to older firmware to install (for European variants)... Even changing the thread title and op to reflect US998 inclusion.
[LG V30 Questions & Answers] ronnbon:
Hello,

I have an H930 model with 11m firmware.

I am still locked- but already have the bin file optained. The last two days I am reading to be prepared for everything since I have had htc phones the last years and this here is sometimes quite confusing for me.

So, for example, I learned that the 11m firmware is quite tricky in regards to twrp- so I guess I rather downgrade to 10f to avoid unnecessary complications, right?

I am a little unsure what to do first after unlocking the bootloader...

2. Can I just unlock the bootloader and reboot the phone normaly to use uppercut and the flash tool to downgrade the firmware?

3. Than flash twrp and root with super su/ or magisk? ( and the rctd-disabler file)

4. than flash the rom based on the 11m firmware?...

Any advice would be highly appreciated...

Thank you.
[LG V30 Questions & Answers] tt-bert:
So I downgraded to to 10f via Uppercut and now I finally got to access TWRP (10v didn't work either).

But now I have another problem: In TWRP I flashed Magisk and everything and now when trying to reboot I'm stuck at the LG logo.

I can access bootloader mode and TWRP but my device is not recognized by LG Bridge. How do I flash the stock rom now?

How can I flash the stock firmware now?
[LG V30 Questions & Answers] ChazzMatt:
If you have TWRP, can you boot into TWRP? From there, plug into PC and drag the H930 custom ROM over and flash it in TWRP.

You have an H930. This would not work for US998.

Thank you, you really are a life saver. I could install the custom rom and get past the LG Booting screen.

But now i get the error message "Encryption not successful" (in german, so in english it must be something like that).

When I click on reset phone on the same screen (I have no other option) the V30 boots into TWRP.
[LG V30 Questions & Answers] ChazzMatt:
Besides Magisk did you also flash the other two files listed in the op? One is encryption related.

[LG V30 Questions & Answers] tt-bert:
I first flashed this rom:

https://xdaforums.com/lg-v30/development/rom-debloated-stock-rom-11m-t3740564

Entry number 9 in that thread seems to have the same problem but then nobody explains it...

After that I installed Magisk, then no-verity-opt-encrypt-6.0.zip and then lgrctd-disabler-1.0.zip

The Encryption screen is white with some blue and black text in german. Translated it means the following:

"Secure Starting

Encryption not successful

The password you inserted is correct but the data is corrupted. For you to be able to continue using your phone you have to reset it...."
[LG V30 Questions & Answers] ChazzMatt:
Before your flashes those files in TWRP, you need to wipe your data. That one encryption file should turn off encryption.

Maybe you need to wipe again.

Did anybody else experienced the no-fastboot-able-original LG usb-cabel?

First- to get my unlock bin code- I used an usb cabel from anker. For the unlocking and rooting etc. I started with the original usb cabel from LG. And got stuck in fastboot mode because the device didn't react to fastboot commands.

Because of my experience before I knew that that was not a device-is-not-properly-recognized-by-my-computer-problem and I changed cabels... and voila- no problem with fastboot anymore.

In case this is not just my cable- kind of sneaky by LG, don't you think?
[LG V30 Questions & Answers] tt-bert:
Yes, I tried multiple times with all kinds of wipes including data wipe after flashing the custom rom.

Might it be the rom? Is there anotherone I could try?
[LG V30 Questions & Answers] ChazzMatt:
Yes, there's another H930 ROM you can try. I only suggested that one because it was simple debloated stock.

Hey guy's been looking real hard at getting this phone but wasn't sure about bootloader unlock until I came across this forum. I think I've read all the post's but I've not seen any one talking about all the carrier's I'm on Verizon so I guess my question is if I do all the steps in the OP does anyone know if it will work on Verizon? Thank you.
[LG V30 Questions & Answers] jcsww:
No! The carrier models are more than likely not rootable. However, there is a T-Mobile (H932) thread where most of the effort seems to be for any carrier related version.
[LG V30 Questions & Answers] tt-bert:
Problem solved.

I forgot that I made a Backup after flashing TWRP and before flashing anything else. The problem with the "Safety Start" screen was that the data partition needs to be formatted, not only wiped. Others had the same problem, see TWRP thread.

SUCCESS!!! i'm rooted with TWRP/Magisk on 10c. thanks for everyone's help...

A COUPLE QUESTIONS please:

i want to make sure i don't somehow bring back LG stock recovery. now that i have TWRP/Magisk installed, what is the proper button combo to boot into recovery w/o risking a LG factory reset? i want to flash freely without worrying i'll erase the new recovery. sorry if i missed this in the forum.

also, the LG pre-boot warning screen for being BL unlocked... do we have to deal with this screen forever now, or is there some workaround to remove it?

TIA!
[LG V30 Questions & Answers] ChazzMatt:
Safe way is to use fastboot command to boot to TWRP.

Maybe custom ROMs have removed that annoying bootloader unlock screen, I don't know. In other LG forums, they've provided TWRP-flashable graphics to replace that, but not here in this forum yet.
[LG V30 Questions & Answers] breacherman:
When first getting into TWRP, I come to a password screen, which says Mount / decrypt data at the top, havent seen anyone mention this. What does it expect for a password? I tried my LG pin, backup password adn default_password, it's not accepting any of them.

Can he not use RebootManager? in the play store. He has Magisk installed for root. I use it on my HTC 10 all the time Dont know if it will work on the V30 or not. Oh by the way I get my unlocked V30 in 2 days.
[LG V30 Questions & Answers] ChazzMatt:
Yes. Good suggestion on that app.

I've used ROMs so much the past several years, I expect "boot to recovery" to be on the power menu. ;) And then when it's not...

I tried to add it with Gravity Box, but it's still not showing up.

Sent from my official open market LG US998 V30+
[LG V30 Questions & Answers] Wotta:
Magisk Manager, which is probably installed on your phone already, can boot you directly into recovery. It's a menu option.

Or you can attach via USB to a computer and use adb reboot recovery (or something close to that; that's from memory.)
[LG V30 Questions & Answers] Mystogan:
noob questions here as this is my first ever device with a non-removable battery. If one was to get stuck in a bootloop, how do you get out of that? in case the reset(vol down + power 7secs) doesn't do anything? Maybe adb can help? reflashing firmware? we have root, but it would be helpful to know how to get out of a sticky situation.

Here goes another....On my previous device the LG G3, when messing with a custom kernel, with the voltages in particular. When undervolted too low, the phone would work fine and was very stable under stress. However, if i were to reboot it at those low voltages, the phone wouldn't reboot, it would just stay off and i would have to pull the battery and re-insert it to be able to boot. Since we can't pull the battery on this phone, would that make undervolting dangerous or is there a way to get it to boot? Unfortunately I can't test plugging in the charger or to a pc since the phone is dead and didn't think about doing that at the time. Anyone with a removable battery device mind testing it?

i installed the WETA rom and am now using SuperSU that came with it.

for reboots, i'm using the official TWRP app for now.

WETA is basically stock with V4A and a couple other minor things. i want it for the audio, but this rom needs some features... like the advanced reboot dialog for sure. thanks for the feedback btw.

by the way, the WETA rom has it's own advanced reboot menu included by starting the WETA app.

the only thing i'm currently wishing this rom has is long-press-back-to-kill. aside from that i'm kinda good to go over here.... also audio focused and not needing endless features, just usability ones like back to kill. is there a way to add that feature w/o recompiling? i think i know the answer...

Please ADD this to your directions in your first post to this version of TWRP for the US998:

[US998] TWRP unofficial alpha [Feb.17.2018]

https://xdaforums.com/lg-v30/development/us998-twrp-unofficial-alpha-t3751204

That way, H930/H930G users have a TWRP and US998 users have a TWRP. POST BOTH in your directions, since this tutorial is not necessarily US998 specific, right? The ONLY item specific to the US998 is changing the drop down menu on the LG Developer Bootloader Unlock website. The rest applies to all H930/H930G/US998.

That US998 TWRP will also work on the H930/H930G, but should cause less confusion for US998 owners who wonder if they can use that other TWRP.

I suggested to the dev he should consider making a "universal" TWRP, since the other seems abandoned and he said he would think about it. Right now he just wanted to make a TWRP for US998 to help development.

He's also the dev who make this US998 ROM. Go thank him and or donate. I've done both!

Another tip...

After installing TWRP, it's a good idea to download

TWRP Manager from the Play Store

.

From that app, you can easily reboot into TWRP without doing the power/volume button dance. In the app's settings, change app start up screen to be reboot options. That way, every time you open the app, that's the immediate option you can choose.

I edited post #2 to include this, but worth separate post to bump this thread up.

Having what seems like a minor issue at Step 7

7.	Turn off data encryption and install stuff… all in TWRP:

a.	Wipe Data – Factory Reset

b.	Wipe Data – Format Partition

c.	Install – set storage to the External SD

d.	Install the Magisk zip

e.	Install the no-verity-opt-encrypt-6.0.zip

f. Install the LG-rctd-disabler-1.0.zip; this reduces LG root checks, which may impede performance.

g.	Reboot – to System

I can install everything until step "F" for RCTD Disabler. Basically throughout I'm getting a "unable to mount /system: Structure needs cleaning" error, but things seems to go okay.. but when I try to install RCTD Disabler it fails outright due to "/System not RW" and the whole "Structure needs cleaning".

I've tried going back to square one and restored the entire system from backups and tried all the steps again, but it continues to show that error. How can I "clean the structure" and/or make /System RW??

Thanks all.

--edit-- I got the same error when trying to install WETA v1.5, but perhaps gives more useful info... Full error...

Warming up...

mount: failed to mount

/dev/block/platform/soc/1da4000.ufshc/by-name/system at

/system: structure needs cleaning

.... however, after hanging at 20% complete for a minute WETA install did continue and succeeded.

6.	Back up the system. This isn’t essential, but you’d be silly not to.

a.	In TWRP, set system writable I do not see a options to set system writable.

b.	Select “back up”. Note there’s no data, because that partition is encrypted.

c.	Select the SD card (or USB; I use a micro SD card.)

d.	Back it up. This will take around seven minutes.

7.	Turn off data encryption and install stuff… all in TWRP: I dont see this option as well.

a.	Wipe Data – Factory Reset

b.	Wipe Data – Format Partition For wipes could you please be more specific as what to wipe?

c.	Install – set storage to the External SD

d.	Install the Magisk zip

e.	Install the no-verity-opt-encrypt-6.0.zip

f. Install the LG-rctd-disabler-1.0.zip; this reduces LG root checks, which may impede performance.

g.	Reboot – to System
[LG V30 Questions & Answers] ChazzMatt:
When you first boot into TWRP it will all you if you want TWRP to write to the system. You have to swipe right at the bottom for yes.

If you don't, you'll never see that option again. And that is why you don't they see other associated options.

You will have to reflash TWRP, and hopefully you'll see the "write" option at first boot.

[LG V30 Questions & Answers] DrPhant0m:
I just got a US998, and performed the bootloader unlock. Having had a US996, I was pretty confident with what I had to do to get started, but I was unaware of the need to flash "no-verity-opt-encrypt" (Step 7e of the TWRP installation section in the OP). So... I did not flash it. What does it do? I remember "dm-verity" being a thing with my Note 4, but I'm not sure what exactly I'm missing out on.

I'm not having any trouble booting to TWRP, and my phone works great. I've used root-enabled apps, I've copied things to the internal storage and my external SD card. The only issue I can think of is that when I went to format everything in TWRP to prepare to flash, the log mentioned failures to wipe certain items. But like I said... everything works fine and it booted up afterward with Magisk and root, so I left well enough alone. Actually, I figured it was a bug in the "alpha" TWRP for US998, and it would be fixed in future revisions.

What am I missing? If I should flash it... can I just do so, without formatting anything else before or afterward? I don't want to have to copy all of my internal storage to my PC again and back again, but I will if it means I'll have a better or more complete experience with my phone. Especially if I'll need it when Lineage or other AOSP ROMs are polished.
