Alright so I flashed the Clasic ROM from Chaz, still boots to TWRP. Please help me out!.
[LG V20 Guides, News, & Discussion] Artimis:
If you've followed all my previous steps before then the last thing you can try is to:

1) Power off the phone completely

2) Hold the Volume down key and power button until the LG logo appears

3) Release the power button for one second and then press it again (continue holding volume down this whole time)

4) You should be brought to a white screen asking if you want to do a factory reset. Select "yes" to both prompts

5) You'll be booted into TWRP again

From there, you can try rebooting into system.

If that doesn't work, you could try flashing TWRP again. Other than that, I'm out of ideas.
[LG V20 Guides, News, & Discussion] Eduro:
Dude you are a genius. The phone is booting, with static, but I guess that's normal and that its going to take a while. Correct me if I'm wrong. Either way, THANKS!
[LG V20 Guides, News, & Discussion] Artimis:
Glad I can help. Yes, static is normal depending on the kernel. I'm a big fan of the Restocked 1.2 kernel as it gets rid of the static on most variants and is a solid kernel. Don't know about Sprint though.... you'll need to check.
[LG V20 Guides, News, & Discussion] dpwguenther:
Hey, so I did a factory reset and started all over again , this time , instead of flashing supersu first, I flashed the backupboot then tried to flash supersu but I don't have twrp anymore and can't reflash it, any ideas ?
[LG V20 Guides, News, & Discussion] Artimis:
Figured that might happen. Assuming you are booted up and USB debugging is enabled, you can follow the steps I posted here:

https://xdaforums.com/showpost.php?p=72245004&postcount=2487

You don't have to flash Restocked (not sure what variant you are using) but I recommend it if you are on a VZW or AT&T variant.
[LG V20 Guides, News, & Discussion] dpwguenther:
I'm on at&t , I just did the whole thing over again, without flashing bootbackup, just ganna see what happened, if it still can't boot , should I flash bootbackup and then restocked? Also how can I tell if my bootloader is actually unlocked because everything says it's still locked
[LG V20 Guides, News, & Discussion] Artimis:
Flashing boot backup is not necessary. Your bootloader will always show as locked with this method. You know you are unlocked if your flashes through the bootloader have been successful.
[LG V20 Guides, News, & Discussion] dpwguenther:
Ok, thank you very much, rooting with a method like this is totally new to me, and now I have a secure boot so am I correct in assuming I need to wipe data?

Edit: I got it to work, thank you so much for your help
[LG V20 Guides, News, & Discussion] Eduro:
So I waited since yesterday, the rom booted up but it has been stuck on "Configuring your phone" for over 12 hours. What should I do? I can't access TWRP anymore.
[LG V20 Guides, News, & Discussion] emdroidle:
There is an effort underway to get the H990DS rooted, the signs are hopeful, but it isn't yet complete (the hardware of the H990DS is different enough to be troublesome). I haven't seen reports of the F800 getting rooted, so the best answer may be to keep the H990DS and wait for root to be finished.
[LG V20 Guides, News, & Discussion] LASERWOLF452:
so i am doing this method on my phone and when i get to step 3, my phone just stays on verizon boot screen i even waited 20 min, so i do the boot backup and i get this so any ideas how i can get twrp installed and this thing rooted thanks

i reflashed the stock rom with uppercut causei am staying way up to late working on this method
[LG V20 Guides, News, & Discussion] rholm:
Ok, I tried to do this twice yesterday. Both failed at step 7. I have a vs995 with 11A and the last "adb reboot recovery" boots to a static screen. It's​ in Android, so I clear it like stated in post 2. However, I'm not rooted and can't get to TWRP. Everything seemed to work otherwise. I flashed SuperSu via TWRP sideload. Is that ok?

Question, if I'm going to cash a custom ROM, can I do that after the decrypt step. I don't care about a rooted stock setup. I want to flash the WETA ROM with the Werewolf kernel.

Thanks for any help!

Cheers,

Rich

Does this work on the H910 running April 1st, 2017 security patch? If not, is there a way to downgrade via KDZ to an earlier version??

---------- Post added at 07:25 PM ---------- Previous post was at 07:22 PM ----------

Are we out of luck? I too have the April 1st, 2017 and cannot get root. There has to be a way :(
[LG V20 Guides, News, & Discussion] cityneversleepz:
sorry for the slow reply. I've been off the grid for the past few days. Yes it is from cellular stream. I think the phone is new. I didn't see anything about refurbished. it came zv3. I let it take one update to zv5 and then turned off auto updates. It is a great phone. No problems at all. I didn't root yet. I am still waiting to see if anything better comes along. I like the second screen. Battery life is really good too.
[LG V20 Guides, News, & Discussion] rholm:
I had the problem you describe. TWRP was overwritten. 2 questions.

1. Can I use boot to recovery instead of the hardware keys? What does pulling the battery do?

2. After the decrypt, can you reboot to recovery and flash a custom ROM?

Thanks! I guess that was 3 questions...

Cheers,

Rich
[LG V20 Guides, News, & Discussion] Artimis:
1) After flashing TWRP through the bootloader, I don't know of any fastboot commands to get you into recovery. If you let the phone complete the next boot cycle and then ADB reboot recovery, it will be too late. TWRP will have been overwritten again when the boot cycle completes. Pulling the battery while in the bootloader just ensures the phone Powers off so you have the opportunity to use the hardware keys and boot into recovery before the boot cycle completes so TWRP doesn't get overwritten.

2) Sure, you can flash a custom ROM.
[LG V20 Guides, News, & Discussion] Modigma:
H910 now thinks it's an H996

Fastboot screen tells me my H910 is now an H996. Is there a way to fix this or am I stuck with it.

I'm thinking it has something to do with step 6 in the OP. when trying to flash bootbackup.img, I get an error 'cannot load bootbackup.img'

The reason I ask is based on the fact I'm trying to go to this ROM https://xdaforums.com/v20/development/h910-att-nrd90m-modded-notsostock-rom-t3525344.

Currently on WETA

I could just use the 996 version of that same ROM, but, I would rather it be correct if I can make it so.

I got it figured out.

Thanks
[LG V20 Guides, News, & Discussion] rholm:
The problem I had is from decrypting the data partition to the next boot. TWRP was gone and Supersu was not installed. So, my question was booting out of recovery after the format. After that, TWRP was gone. Should that happen?

I don't care about a rooted stock. I want to load WETA.

Thanks!

Cheers,

Rich
[LG V20 Guides, News, & Discussion] Artimis:
Decrypting data is fine but when you do that, you are wiping data which is wiping SuperSU (this is a system-less root). Since SuperSU is gone, there is nothing protecting TWRP from being wiped since you are still on a stock system

You need to follow my previous instructions for getting TWRP back and ensuring it sticks. You can install a custom ROM once in TWRP just as well and you should be ok.
[LG V20 Guides, News, & Discussion] rholm:
Got it! Doesn't that mean that 4.1, 4.2, and 4.3 are out of order in the OP? If I flashed SuperSu, then format data and then further wipe data, isn't SuperSu gone?!? That explains my problems.

Thanks!

Cheers,

Rich

I just got a LS-997 on ZV3. Should I take the OTA? Will it jump directly from ZV3 -> VZ6? I would like to get the radio on the latest version before unlocking and flashing a custom recovery. My phone wont be activated for a few days, so will I have activation issues if I do this prior to getting my sim for activation?
[LG V20 Guides, News, & Discussion] fiver5:
I rooted / rommed before activating my 997 on Sprint with no issues.

Going back in tonight. Thanks for your help. If the id command in Terminal still shows untrusted. Is my bootloader still unlocked?

Thanks again!

Cheers,

Rich
[LG V20 Guides, News, & Discussion] Artimis:
If you KDZ'd back to stock then your bootloader is locked again. Showing as untrusted is good though because it means the dirty cow exploit will work. Additionally, the bootloader will always show as locked whether it really is or isn't using this method. The only way to really know if you are unlocked is whether or not the fastboot flash commands (e.g. step3) are successful or not.

If you haven't KDZ'd back to stock then you are most likely still unlocked.

Vs995 here, been happily rooted for a while now, currently running WETA 4.9.6

At some point while switching roms I did an advance format and checked the system box in TWRP. Everything is still running well but when I try to flash Magisk or the restock kernel I get an error locating system.img or boot.img and installation fails. Pretty sure its because I checked and wiped system when formatting. Old habits. Is there a work around to fix this or do I need to kdz back to stock and start over? Any help is appreciated.
[LG V20 Guides, News, & Discussion] midmadn:
Absolutely not. If you take the update you will not be able to root.

I would root that phone yesterday. It will eventually force the update even if you have auto update off.
[LG V20 Guides, News, & Discussion] emv1031:
Did you find an answer to that question????????????? I´m on the same boat and can´t find info anywhere.... I´d really like to know if someone out there is trying to get past the april security patch, I don´t mind waiting to get root but it would suck if there are no efforts being made, would probably force me to switch to a different phone.

just change your apn type to add dun:

my apn type is:

Here is the guide i used: https://xdaforums.com/sprint-lg-g5/how-to/guide-gsm-unlock-sprint-lg-g5-t3574819

NOTE, I would not do the other stuff... I lost connectivity doing playing with the rest.... Just change your APN type (however you know to do that) and then use built in tether... works great.
[LG V20 Guides, News, & Discussion] emv1031:
Just wondering... are these the same APN settings that can be accessed through the Mobile Networks in general settings, access point names? Changed the apn type as indicated, unfortunately Hostop still gets stuck on AUTHENTICATING until it read authentication was not successful.. bummer...
[LG V20 Guides, News, & Discussion] pigphish:
Yes but you will need to add an apn I believe (if unrooted) and authentication should be NONE. This worked on two non-rooted v20s
[LG V20 Guides, News, & Discussion] emv1031:
do you know if any of those v20s were previously locked to AT&T?
[LG V20 Guides, News, & Discussion] dannieloco:
I haven't found any info on it. I haven't even found KDZ to return to factory so I can then root. All I've found is the h910PR version but I don't want Puerto Rico version software on my Att phone.

Dude god I hope so. I had a S4, which i rooted the day I got it (back when it came out years back) kept that thing until just 2 weeks ago when I researched then upgraded to the V20. Was throwing a fit when it updated. Almost returned the damn thing.

I'm in the same boat. Have had this phone 3 days. Bought mainly for ROM support, but I'm not totally disappointed. Comng from an S7, this is a breath if fresh air. Still has some customization without root. Hopefully the brains behind the bootloasers will get something cracking soon.

Verizon LG V20 on 12A. (rolled back and factory reset from 15A) ADB working fine. steps launched in C:\Android. USB debugging enabled and confirmed. Cannot get past step 1, (no flatland errors). It doesn't work at all. I did this successfully on a different V20, but this one here won't work.

Im sick of Verizon and their locked devices bs. I am just going to have to dish out the money, to switch back to AT&T and get a galaxy s8 international version which i can actually root. Because the V20 sucks and lags like hell without root. I shouldn't have to go through all this to get a device rooted to actually make it WORK without sucking.

I was following the process and got to the point of:

5) During reboot you will get a Red Triangle with a "!" inside, this is normal (First boot after flashing SuperSu will show the Red triangle twice.Wait for system to boot (this will take awhile). It may appear like the system has frozen but it has not. JUST WAIT!

It has come to my attention that some users have encountered abnormally long first boot time(over 20 minutes before first time setup)

To resolve this issue:

Boot into bootloader by pulling the battery and reinserting it and holding VOL- and phugging in the phone. then typing:

Code:

fastboot flash boot bootbackup.img

fastboot reboot

So I was waiting about 30-40 minutes, pulled the battery, booted into boot loader, and entered the code in ADB.
