I will also receive mine soon, so I'm also trying to confirm. From what I have read, I'm hoping it will work but maybe someone who tried it will enlighten us.

edit: [MENTION=3860153]jkjambo[/MENTION] has a message in this thread where he says fastboot flash twrp works, so hopefully we're good.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jkjambo:
That's correct..

US996 can be unlocked officially , so no need dirtysanta stuff.. just get unlock file on lg-dev and then flash twrp usual way with fastboot

Did same thing 2 days ago with another us996

Hi. I have TMO G5 and I have questions coz I'm stuck on flashing no-opt-encrypt on recowvery. Can i just put the no-opt-encrypt zip on my internal memory and manually flash it when recowvery boots my device to TWRP?

And If ever can I flash both SU and no-opt-encrypt zip file? or just one of them? Thank you so much.

I just got my US996 a couple days ago and it worked perfectly for me. I first unlocked the bootloader via LGs website and then I proceeded to use fastboot to flash TWRP. It worked fine but its another story trying to find a stable ROM that I like....

Hi all,

New Android user here. I purchased the unlocked V20 from Amazon. It was sold and shipped by Amazon so I'm assuming it's the 'real' unlocked version? There's ROM threads that mention that a certain ROM will only work on the unlocked US996 but not on the US Cellular US996... I'm a bit confused by this. How can I tell which version of the US996 I have? There's no US Cellular branding on the phone. Not sure if they ever came with that.

Is there any way to go back to stock for the Verizon version of the LGV20 or is this just for US Cellular? If so, can you point me in the right direction to revert back to stock? Thanks

Want to comment that the adb/fastboot in the first post does not work for LG G5 H830 (T-Mobile). The device is connected but no prompt will appear on the phone to allow USB debugging.

Version 1.4.3 from https://devs-lab.com/download-minimal-adb-fastboot-tool.html works
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] redhonker:
Sorry that I must be asking a question that's answered already. I searched and could not find the answer.

I have finished the step and got my H830 rooted with TWRP and SuperSU. But how do I get back into TWRP? If I do the hold-both-volume-down-and-power, see-logo-release-power-briefly, hold-power-again routine, I will get into a Yes/No question whether I'd want to do factory reset. The OP mentioned "factory reset dance". What is it?

Thanks
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] androiddiego:
Follow the instructions to do a factory reset. It will take you to TWRP, not actually do a reset.

With TWRP you have a custom recovery, not the stock recovery that would do a factory reset.

Another option is to install the app "quick boot." Very easy! (Needs root obviously)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] FZRaven:
For searchers

If you get back Enforcing after the getenforce command, check if you issued the adb shell reboot command correctly. I found I had typed adb shell reboot recowvery, the phone will reboot but not correctly, it should be adb shell reboot recovery. Just start back at the command right after chmod 0777 *, where you set permissions. After fixing my mistake everything went smooth as silk.

Hi,

I am trying to unlock bootloader but is gets stuck after after adb reboot bootloader.

Phone (H918 10j) goes into fastboot and I do not have any connection to it after that to send additional commands (adb devices returns nothing)

My device didn't boot afterwards. Shows 'no command' and the android dead logo.

Manually powered down again and rebooted. This time it booted just fine. Odd...

However, when continuing to the next step via 'adb shell' and then running 'getenforce' it shows 'Enforcing' not 'Permissive'.

Found on Reddit thread.

"that explains it... your software version is H91810k, which brings the patch level to May 2017 and the unfortunately fixes the recowvery exploit. last version that is root'able is H91810j, which has the patch level of December 2016 prior to the fix. fortunately for you you can downgrade to 10j, root, and then apply my flash to bring it to 10k."

I'm running the version ending in 'q'...

This will not work if your H918 has software version 10j or later, as the "dirty cow" exploit has been fixed. Currently there is no way to boot unlock and root those phones once the software has updated to 10j and beyond.

Help! TWRP Bootloop issue.

Help! Stuck in the endless TWRP loop! For starters, I'm running TWRP V.3.0.2-1 and flashed the current version of no-verity (Ver 5.2). I followed the steps outlined in the post and still getting the TWRP bootloop. Not sure if I'm doing something wrong but here's the step I took.

First, I flashed no-verity coming from Desolation ROM , then I did a "format data" and then installed the v5.1 ROM. It successfully installed (at least so it says) but when I tap to "reboot system," it bootloops to TWARP!

What am I doing wrong or how do I fix it? If I can possibly go back to stock and start over again, how can I do so? Is there a hidden key (i.e. Vol + or something) combo to access stock recovery and try to restore back to factory settings? The phone happens to be my daily driver. Any help would be greatly appreciated. Thanks

Thanks, found it!

Hey! Thanks for your response. Like they say, Google is your friend. A Google search of Uppercut led to me everything I need to know and how to use it. At any rate, I have been able to return it to stock but my problem now is getting it to boot to TWRP after flashing TWRP in bootloader mode.

Trying to boot to temporarily boot into TWRP (fastboot boot twrp.img [that's what I renamed the recovery image] gives the dreaded "FAILED (remote: unknown command)" error message, using the vol - + power combo key only boots back to the system and trying to issue the "adb reboot recovery" command from inside the ADB folder only boots to the "No command" green android lying on his back screen :(. At this point, I'm inclined to believe that the stock ROM I used to recover the phone has some commands disabled by LG. I'm on SW version 10f.

Again, thanks for mentioning "Uppercut" in your post... it really helped.

I upgraded my US996 from 10f to 10k, flashed TWRP. Removed the battery the first after flashing TWRP, did the Vol - + Power combo thing but still can't get it to boot into TWRP. Issued an "adb reboot recovery" command from system only to get the "No command" green android lying on his back screen. I've also tried to temporarily boot into TWRP via fastboot boot [myrecoveryname.img] but getting the "waiting for device" message.

What am I doing wrong? ANy help from anyone would be greatly appreciated. I like the phone but I can live with all the bloatware from LG if ther's anyway I can root the phone since it doesn't seem to want to boot into TWRP. Thanks in advance!

I know this question and answer are old, but I saw in another thread where at least two posted stated that a custom kernel would be needed to get rid of this screen.

I checked the custom kernel threads and didn't find this fix listed on any of them.

Is the unlocked bootloader warning screen bypassble using a custom kernel? If so, do any of the kernels for the H918 do this?

Thanks,

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dimm0k:
I'm sure it's not fixable through the kernel... I believe that would need to be fixed in the bootloader if I'm not mistaken

"If you're flashing SuperSU.zip, it will also do this for you so this won't be necessary.

Warning: If you don't flash either no-verity-opt-encrypt or SuperSU, you will probably end up in a horrifying never-ending boot loop of "corruption"!"

I initially used SuperSU, so I didn't flash the no-verity. But if you just want to use Magisk, I recommend flashing no-verity.

Try factory reset in twrp. First clear cache and dalvic then go to the factory reset. These lg's are finicky when booting up. Did you make a backup / restore before you did the flashing.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] timoshina:
I already did factory reset as a last step says in the op's post. It's a new phone, so i did not do any backup. What's the easiest way to completely factory reset the phone and start over the rooting process?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] fastjohnson:
Well if you have custom recovery installed do it that way. Try not to reset it through factory settings it causes problems. But in the future always do a backup before flashing anything it's worth the time and storage space to have a safety net. After you do a reset through twrp do a battery pull hold vol down and power at the same time to clear left over power in the phone then power it back up and hope for the best.

Hey all,

I posted this over in the Lineage LG v20 thread as well. [MENTION=5672995]jcadduono[/MENTION] any help is appreciated.

I used the update manager from within Lineage OS last night and downloaded the latest nightly ( lineage-14.1-20180419-nightly-h918-signed.zip), selected reboot device, and now can't get Lineage to boot. Each time I boot I get dropped to recovery (TWRP). I've tried wiping and installing MEGA, WETA, and backups but I still can't get the OS to boot.

Does anyone have any suggestions or know how I can get past this? I was running the previous Lineage nightly ( lineage-14.1-20180410-nightly-h918-signed.zip) prior to the update.

To break the loop totally power off the phone and then manually enter twrp (hold volume down then hold power until the screen turns on, keep holding volume down and tap power until it asks if you want to factory reset, say yes twice). Then do yourself a favor and upgrade to my builds of twrp (install in old twrp by going to install, install image, then browse where it was saved, then tap it, then tap recovery and then swipe or an app in a rooted ROM like flashify works too) which work with lineage otas (and encryption too)
