I'm somewhat confused about how ARB, root, and custom roms all relate and what the restrictions are.

1) If I have stock rooted pre-10p h918, is there a way to upgrade to stock oreo (and upcoming pie) without losing root or tripping ARB?

2a) I see things like 'super rom' will trip ARB. If I'm already rooted, is there any great loss in that? (besides inability to install pre-10p roms anymore. Seems like most either give pre/post options or are ARB1 only)

2b) if I trip ARB 1, will that prevent me from going back to true stock w/o losing root/twrp permanently and being unable to get it back?

Thanks!
[LG V20 Questions & Answers] scorpio76r:
Yes, you can flash either the alpha rom by I95swervin or the pre rooted stock oreo by Dudeawsome. I personally run the Alpha Oreo rom by I95swervin.https://xdaforums.com/v20/development/alpha-omega-rom-oreo-vs995-h910-ls997-t3847510 you will be good to go. Arb 1,being tripped will not effect your phone negatively if you are rooted and flash either rom. Best bet, head over to either developers thread and, check them out.

Hi guys I need some help I have a strange problem that I never seen before when I enter the download mode with my H990DS I have the static screen problem, I can't see anything in download mode because of this. Now I'm afraid that if I ever brick I can't unbrick or flash KDZ's using LGUP.

I wonder if this static affects download mode working at all, I don't remember having to click any prompt in the phone screen, just enter download mode and flash the kdz from LGUP so maybe the static won't affect anything if I ever need to use LGUP? What worries me is how this might have happened....

I've been thinking about buying a used v20 as a rootable phone but it appears like not all the versions of the v20 are made equal. Which ones are easier to get the bootloader unlocked on? I'm planning on using it on a Verison MVNO but I'm 95% sure that any verizon branded phone is a no-go on that front. I've also had bad experiences with the LG developers unlock site with the g5, but I think a lot of that had to do with not all the phones that should have been eligible actually being eligible.... but if one of the versions can be unlocked without all that rigamarole that would be better. I suppose all else fails I can just buy one pre-rooted off of Ebay and reflash the thing for security reasons but I'd prefer to avoid that.

H990DS is what I have, and it has the Dirtysanta bootloader unlock exploit.

I'd recommend it (or the H990 if you don't want dual SIM) from personal experience. If you have a look around at the how to root guides for all the different variants, you can start to gather which are the easiest to work with.

I really hope someone can help me with this situation I'm in.

I have H990TR (Single-Sim Variant), so to root it I used H99010b_00_OPEN_IL_OP_1103.kdz

I followed all steps of dirty santa for H990, while doing it I got stuck at the part where you are greeted with

"Your device is corrupt, enter password to unlock".

So I formatted data, no solution.

Wiped everything (except USB-OTG and external SD), no solution.

Flashed Lineage OS 15.1 and it worked. Then moved to Lineage OS 16.0 and it still works.

Problem is that I want to move to SuperRom, unfortunately whatever I do I keep getting greeted with "Your device is corrupt. do a factory reset" screen.

Is there anyone who has ANY idea how can I fix it?

I tried:

- Installing SuperRom with many variations (no mods/with mods/flash kernel&boot later etc.)

- Downgrading to stock (H99010c_00_OPEN_IL_OP_1219.kdz) with KDZ Writer, still getting do a factory reset.

- Downgrading to stock and then flashing kernel or rom.

Nothing works, except Lineage OS. Help please?

What version of twrp are you using? Also you should search and read in the super rom thread, I think there were reports of issues with that rom on the 990. Also the rom itself is no longer being developed or supported
[LG V20 Questions & Answers] mivvv9lives:
I'm using Unofficial TWRP 3.3.0-0

I know H990 is the blacksheep of V20, always causing some problem; but from the searches I know it is working.

Problem is not only about the superrom, that is why I'm asking this here.

Whether it is rooting a stock, installing superrom or anything using stock rom as basis, it doesn't work.

It either gives me a LG logo boot loop or encryption unsuccessful, reset phone.

I just bought VS995 model and honestly I'm afraid to do unlocking bootloader. I need rooted device or at least I can use modded stock ROM with root access. Is there any other way to do flashing ROM without dirtysanta? I know unlocking bootloader then flash TWRP is basic need for it. But I want to know if there is other way to do it.
[LG V20 Questions & Answers] cnjax:
Nope, you need to unlock the bootloader in order to have twrp, and the ability to flash roms and root
[LG V20 Questions & Answers] Arya_3RDNumber:
Yes. I understand about it. So, is dirtysanta are the only way to unlocking bootloader?

Already read the guide for VS995. Wondering if everyone did a lot success or not.

Anyway, thanks for reply :)
[LG V20 Questions & Answers] mivvv9lives:
Well I fixed my problem with combining these solutions:

- Downgraded and removed root/recovery by using LGUP to flash H99010c_00_OPEN_IL_OP_1219.kdz

- Followed DirtySanta's rooting instructions letter by letter (last time I messed it up by allowing it to boot without flashing kernel)

- This time installed TWRP-3.0.2-1 instead of newest one.

- Flashed "H990DS 20a Oreo flashable" by dudeawesome, MK2000 kernel for H990TR by askermk2000 and Magisk.

Now everything is working fine without any trouble, thanks for all replies. I hope if anyone with H990TR variant will save themselves a trouble that I went through.

[LG V20 Questions & Answers] DaCHeF36:
I think, after hours of reading, I understand that the VS995 on vs99520c that I just bought can't be modified. I can't boot into fastboot mode because, as I understand it, all carriers but T-Mobile pulled it a while ago. Most of the Verizon methods I see require fastboot. The device appears to have the stock recovery installed. When the phone boots, I see an unlocked padlock, which I assume means the bootloader is unlocked. Since I don't have fastboot I assume I can't do much else.

I was looking for the last good user-replaceable battery device, and I thought I had found it. Before I return this device and cry, is there any hope at all? If I still want this device, and I am stuck on Verizon, are there any other viable options? I appreciate the advice, guys.

Edit: After some more reading (I was getting there) it seems that the VS995 is unaffected by ARB. I should be able to rollback and apply Dirty Santa.

Edit3: After following DirtySanta, and ensuring the scripts executed properly, I was able to gain access to Fastboot with the new boot image. What I found difficult to discern was the fact that Fastboot is only available AFTER the patching. I am glad it's solved. :good:

Having issues with my V20 H990DS TWN Model following root.

I rolled back to 10c version to use dirtysanta, followed through with all the steps and seemed to go well - TWRP is all installed and working.

However, every time i go to boot any rom (i've tried super, lineage and the oreo h990 roms) i get the secure unlock screen.

i have tried reflashing the boot image within twrp based on threads indicating it might have rolled back.

Some threads have indicated i should delete the lockdb in /data/system/ but that folder&file does not exist.

At this stage, I'm not fully sure what i'm missing but i'm getting lost in the world of xda, so hoping someone here might be able to tell me what i'm missing

Restarting it..(multiple times.),

remove battery and let it sit a few mins then turned back on,

Uninstalled all google play store updates, then updated google play store

installed LG updates that were pending.

Have been using Samsung, BUT some of the things I want are just not there (FM radio,removable battery, and few other), so this is first LG for me. Just got second hand LG V20 h910. Would like to get rid of AT&T bloat. Been Googling putting different firmware on it (H915 US966). From what I can find, US966 is US Cellular/factory(?). I have thought of rooting and installing custom roms, BUT it breaks some features (FM radio for one).

On phonemore.com it has this: 1st one for US966 2nd for H910

GSM Mhz band	Quad-Band 850/900/1800/1900	Quad-Band 850/900/1800/1900

Primary 2G network	CDMA 800/1900, GSM 850/900/1800/1900	GSM 850/900/1800/1900

Primary 3G network	CDMA2000, UMTS 850/900/1700/1900/2100	UMTS 850/1900/2100

Primary 4G/5G network	LTE Cat12 700/800/850/1700/1800/1900/2600 (2,3,4,5,7,12,13,17,20,25)	LTE Cat12 700/800/850/1700/1800/1900/2100/2300/2600 (Bands 1,2,3,4,5,7,12,17,20,30)

What I am trying to understand is under 2G/3G CDMA and GSM are listed, does that mean the modem files contain info to operate in both? Or is the CDMA section for U.S. Cellular and 2nd part for factory?

Thanks in advance.

Hello all,

I currently have no interest in going away from stock (too many handy features that I use often that would be lost, including proper use of the second screen) but I do have interest in upgrading to pie, and as I have a US996, I am assuming that I'll have to do this unofficially. So, my question is: has the Korean stock pie firmware been ported to US variants yet? If not, why? I know for a fact I'm not the only one who prefers stock firmware on their V20. I'm so close to trying lineage OS but the lazy use of the second screen is a deal breaker for me.
[LG V20 Questions & Answers] cnjax:
No ports have been made for the US variants as the majority of devs have abandoned the v20 ages ago.
[LG V20 Questions & Answers] alexandero11:
Well, if that's true then that's quite sad and is a complete about face to the mentality that most devs had only a few short years ago. The LG V20 is basically the next HTC HD2, it can run anything and has a variant with an unlockable bootloader so there really is no excuse aside from changing culture about consumer rights and coding challenges. Very sad. I honestly plan to attempt to teach myself to make such a port since it would be relatively straightforward. The fastest phone ever made with a removable battery doesn't have a historic level of dev support? And no OLED to burn in? And it's one of the most repairable smartphones ever made? That sort of defies common sense that support would be dropped by so many devs, especially considering how dirt cheap even brand new units are these days and considering how the SD 820 is more than usable in 2020.

The V20 is now almost 4 years old. With manufacturers releasing new phones at the blink of an eye. Your phone quickly becomes dated. Devs are still out there developing but they have moved onto the latest and greatest devices. LG is to blame, it took forever to get oreo, then right after they stopped releasing security patches. The V20 was a flagship phone so we should have gotten at least two OS updates ie Pie, but they screwed us. Because of this numerous v20 owners have stated they will never buy another LG phone.
