If you used my method your aboot and boot files were automatically backed up when you ran my scripts. Look in the folder that you extracted the zip to and you should see abootbackup.img and bootbackup.img

Edit: i see you installed a custom rom. If you didnt backup your stock system partition then you are screwed.
[LG V20 Guides, News, & Discussion] capfirepants:
Would he be able to use another phones backup partition?

Edit: Also, does this mean the method works but the rom just doesn't boot up after?
[LG V20 Guides, News, & Discussion] 881jz:
thanks me2151 . I did use your method, and unfortunately too late when i checked the step2.bat that backed up the aboot.img and boot.img, which is a very handy step to have.

I was relying on TWRP backup too, the TWRP/backup folder is there but the backup was not present, i suspect it failed and i didn't bother reading the display.

i had another play today, tried the LS997 rom linked in the root thread for the sprint edition. looks like the 'static\snow storm' i was experiencing after flash only happens when i am still connected to the PC and in download mode. i got the full 'android is updating' screen, at 100 of 100 i received a kernel crash.

i am no expert (obviously) but i do think this method works, just need a rom/modem/kernel to use post root. the stock system failed to boot after recovery flash, unfortunately i did not grab any logs. still get the corrupt device red triangle message every boot which i assume is the nougat built-in security warning.

i am happily using my old phone which is quite functional and has root. So will wait to see what comes out of this bounty thread and the community for root that may restore my H990DS to a usable level.

if i can assist a dev with testing anything, give me a reply/PM.

Sounds very promising.... Thanks for the update
[LG V20 Guides, News, & Discussion] Byte_76:
I agree with earlier comments that it does not seem like your V20 is entirely bricked.

I imported my 990DS from Taiwan because the V20 isn't available in my country. With the poor exchange rate, it is cost me a pretty penny and is my primary phone so I cannot take the same risk that you did. Much like other members here, I am desperate for root and holding thumbs that it will come at some point in the near future.

So, from my side, thank you for trying this on your 990DS. I am hopeful that it may lead to positive results and perhaps eventually a working solution that all of us 990DS users can enjoy.

I've been successfully using the LGV20 H990DS rooted by this site for the last 2-3 months.

The two main issues are:

Video doesn't work. Camera takes pictures but when taking video it freezes on the first frame and then you can only hear the audio and the first frame of the video is stuck there on the screen. Ironically video calling works fine.

Any OTG cable crashes the phone. It's not just HDMI OTG, it's OTG storage, OTG hardware wallets, etc.

I did send some cash to [MENTION=3693948]embroid[/MENTION]le in appreciation, the phone works fine, but I'm about to flash back to original stock and sell it over the video issue. (missed a few precious moments with my kid)

[LG V20 Guides, News, & Discussion] speculatrix:
My 990DS has been very solid. I haven't used the kdz tool to install any updates *yet*, but I will. I did apply the thermal config hack for better performance:

https://www.xda-developers.com/lg-v20-mod-stops-slowdown-charging/

Personally, the lack of video recording is an annoyance, a small price to pay for the freedom to use Titanium Backup, the above thermal hack, full linux image install into a memory card partition and other things.

[LG V20 Guides, News, & Discussion] ThomasKHL:
Hi,

Mine was bootloader-locked as well before TWRP & Rooting.

But there's way to unlock it as taught by the tutorial on the 1st page of this forum.

Steps must be carefully & strictly followed even a miss of space would make you fail....

I didn't have SIM card inserted during the process but I don't think it's a concern.

[LG V20 Guides, News, & Discussion] ThomasKHL:
Hi,

I flashed the h990-kernel.zip as per attached.

After TWRP & Root, I flashed h990-kernel-v0.2d-fix-jahlex.zip to fix my camera focus issue.
[LG V20 Guides, News, & Discussion] emdroidle:
This shouldn't be necessary. Simply flashing [MENTION=1657835]jahlex[/MENTION]'s kernel and never bothering with mine should work perfectly. The reason for replacing the kernel is the updated ones have a better display driver which fixes the static issue (which is otherwise much worse than other V20s).

Ok guys, I'm planning to root using this soon, but one question. After I root, will I be able to get the latest security updates without a problem? Thanks in advance!
[LG V20 Guides, News, & Discussion] Redline:
Yes. A TL;DR of the process is that you flash a rootable KDZ following instructions in the OP, then you can update it via KDZ Writer to get the latest security patches.
[LG V20 Guides, News, & Discussion] p7810456:
Thanks! And one more thing, is anything that came with the phone broken in the new kernel (e.g. Hi-Fi DAC, Bluetooth, second screen, etc.). Also, is there any way to change the "phone corrupt" triangle to something else? Thanks again!
[LG V20 Guides, News, & Discussion] Redline:
No, you can't change the triangle. Wear it as a badge of honour.

[LG V20 Guides, News, & Discussion] Pataforce8:
Confirmed working for me. $10 coming emdroidle's way. I got stuck in a bootloop the first time but got it to work the second time. Not sure what I did differently.

Device: H990DS

Kernel: H990-kernel-v0.2d-fix-jahlex.zip

KDZ: Singapore "g" (Rooted with H990ds10c_00_OPEN_SG_DS_OP_1214 then used KDZWriter to upgrade to H99010f_00_OPEN_SG_DS_OP_0630)

Root method: Tried both SuperSU and MAGISK, both worked

Xposed framework is working, only using Viper4Android for now. Only root app I can't get to work is Sixaxis Controller.

Only thing that doesn't work now is USB OTG. Between this and Sixaxis not working I can no longer use my Dualshock 4 controller, which is a bummer.

I would love to have a few custom roms to pick from but I'm sure that will come in time.

Please head here for a very nice explanation of this issue by Stephane2048 and more :)

Shoutout to emdroidle & ahlok_hk

==================================================================

Hello,

This doesn't seem to be working on my h990ds from India.

Everything works till I flash the TWRP and reboot.

I am getting garbled up screen and cannot boot into TWRP :(

The phone is unbricked thanks to the brilliant backup plan using the .kdz files.

I initially thought it could be because of the kdz I was using - H990ds10f_00_OPEN_ESA_DS_OP_1227.kdz (This is the oldest of the Indian firmwares)

Then I downloaded H990ds10c_00_OPEN_SG_DS_OP_1214.kdz (meant for Singapore) and the result is same. :crying:

Any help would be much appreciated!

Thanks!

Initially you'll need to go back to 10e or earlier. This is necessary for installing the unlocked aboot. After the rooting procedure is done, KDZ Writer can upgrade you to a later version.

Stuck while going back to Stock

Hi Experts!!

The complete guide for rooting LG V20 H990DS works flawlesslesly. I had rooted using SuperSU and after reading the profits of Magisk tried going back to stock.

I did all the steps mentioned in the first post by [MENTION=6984210]emdroidle[/MENTION], and attempted the Step 1a. flashed 10c_00_OPEN_TW firmware.

It got completed.

But upon booting up, i am getting Settings keeps Stopping Popup ('X Close app' beneath it.)

i tried flashing the firmware again, but the same result.

Please help me out. I am not able to boot the device.

Thanks in advance

I think this should work .

https://xdaforums.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

You probably flashed the wrong firmware. There is no kdz for Indian models pre 10f .

---------- Post added at 07:34 AM ---------- Previous post was at 07:31 AM ----------

If there is any alternate link to download kdz files for Indian model - (IND Asia IN/India) please do let me know. The oldest firmware i can find is 10f and I don't think it will work with this method. Correct me if i am wrong.

[LG V20 Guides, News, & Discussion] emdroidle:
You're welcome. Sorry about being slow at passing an update to [MENTION=3102329]roosta[/MENTION]. I was being a bit focused on getting things in to shape for LineageOS, then the past 2 weeks were very busy due to participation at an event.

LineageOS is being a bit interesting for the H990* devices. LineageOS's policy is they want kernel updates to be directly flashable and the method I used doesn't meet this qualification. When installing the kernel .zip file, it modifies the kernel command-line to pass the device variant and SIM count to the kernel (the `fix-h990-cmdline` program in the .zip file); this in turn is used for the modem fix.

Almost got the bits in place, just one last step... Hopefully you'll soon see a note on [MENTION=2881807]x86cpu[/MENTION]'s unofficial LineageOS thread soon.
[LG V20 Guides, News, & Discussion] roosta:
Hi everyone,

I will soon wind up support for this thread, as the phone is long gone for me...I pulled out

However, i don't believe any one her epulled of this thread earlier than when the bounty was claimed by @emdroidle

It's been a LONG time since it was released and these names will be handed over to the mods within the next fortnight. If you have made a pledge and haven't paid it, I'd suggest doing so...or these sweet mods will stop coming for current and future phones if this is how we treat the people who are brave enough to take up the job and spend countless hours.

There's real;ly no need to involve me, if your name is below and you have been notified, then

1) Make the pledge to @emdroidle that you promised; message him or find his explot thread with payment info

2) Ask that he PM me to remove you from the lift (I can't check his paypal transactions, so don't send to me

3) Your name will be taken off the list and won't be passed onto mods from March.

It's that simple guys. I'I'm expect all those who made pledges do the right thing and contribute the small amount you have promised, or at the very least - somrething!

This worked a treat with my H990DS other than swapping SU for Magisk.

LG should be rewarding you, I sure as hell wouldn't have bought the phone if this wasn't possible.
[LG V20 Guides, News, & Discussion] speculatrix:
I really should switch to Magisk to see if that will get internet banking to work again.

And yes, it was only the promise of unlocking my phone's bootloader and achieving root that caused me to buy the phone.

If mine broke, I'd probably buy another, depending how things work out owning a Gemini "PDA". I note that prices of the H990DS haven't really fallen much since I bought mine.
[LG V20 Guides, News, & Discussion] masteryx:
I don't know how much this contributes to the general knowledge, but I am in the same situation: I have purchased this phone only after [MENTION=6984210]emdroidle[/MENTION]'s breakthrough. I was eyeing it for two months in advance and only shelled the cash once rooting was possible. I have not yet rooted it, but knowing I can do it anytime I choose to was the main reason for the purchase (after the obvious commercial reason of excellent bang-for-buck ratio).

when running lg update for checking updates to LG apps and it found some, it locks the corresponding apps until the update has been applied. I don't like this behaviour, it looks like an hijack from LG. Could anyone tell if it's possible to unlock those apps despite not installing the updates found?
[LG V20 Guides, News, & Discussion] hotcell:
What apps specifically? One obvious way is just to remove these apps and find replacement. Would disabling check for the app updates keep the outdated apps locked? If the app has system level nonstop services, the locks are technically reasonable to prevent unintended and possibly damaging behaviour.
[LG V20 Guides, News, & Discussion] :
any of the LG stock rom

I can probably remove them only because my phone is rooted, but don't know how to do. I don't think there is a replacement to all LG apps.

It's always disabled. I accidentally ran the search for updates by clicking on "About/Common/update center/applications update" (i translated from french without checking, so the path might differ a little). When clicked there i though it would ask for some confirmation but it actually ran it.

???
[LG V20 Guides, News, & Discussion] hotcell:
You can uninstall, freeze or hide unneeded apps, incl. LG's own.

If you switch off notifications in settings, there is less chance you'll have to decide whether to allow updates or not. But the entire process is short in time, so I don't see how an app lock would affect general usability.
[LG V20 Guides, News, & Discussion] :
i was meaning any app for which LG update tool finds an update gets locked, not general usability. I switched off all automatic checks for updates since long time. As i said in my previous reply, i accidentally ran the update process by simply "clicking" on "About/Common/update center/applications update". I was expecting there was one more step to run the process. I noticed just recently that those apps have been unlocked. So it seems they have implemented a count down during which those apps would be locked. That really sounds like cheap tricks to frustrate people and force them applying updates of these proprietary and closed source apps.
[LG V20 Guides, News, & Discussion] hotcell:
If auto-update switched off, there should not be any attempt to apply updates. Otherwise it's a bug to report LG. I personally keep weekly notifications and have auto-updates switched off, never noticed any lookups or unattended app updates. I think the updater might try to connect and find out whether updates avail. at the stage you described. But it shouldn't try to update if autoupdates were disabled. Anyway, when rooted, you can remove those apps completely. You can even remove or block LG updater itself, either FW part or whole. Although I don't see any value in keeping LG apps outdated on purpose.

you're not answering my question which was about unlocking apps locked by LG update tool, and you don't seem to comprehend what i meant.
