magisk is flashed after kernel, because it patched up the boot image, as your boot image was already patched thats why you did not faced any issue.Next time, keep in mind, first kernel than magisk or Super SU to gain root access.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
Oh I did this because in magisk thread it says to flash it before the kernel, but I'll keep this in mind and flash kernel first, also thanks for the help with the updates

hi everyone, my h990ds cant boot into recovery. Everytime i try the TWRP splash screen shows up like for a second but doesnt go through then show the LG logo then it boots to system. Bootloader seems to be locked also, after rebooting to bootloader and typing fastboot device in cmd it only says "waiting for device". I already have the oreo 20a but now I want to try this one but i cant do so because of this problem with my phone. Can someone help me please? Thanks in advance!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sajadzare:
Put device to fastboot mode by pressing volume down and connect usb

Let pc to install driver.

Open fastboot folder in pc then flash recovery again with fastboot flash recovery recovery.img

does someone know where to get the stock roms checksums?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] albaniax:
Hey man, which Oreo KDZ do you use in this case - one of the official Oreo Firmwares?

Does it also work if there is a region mismatch?

Also in last step where you say "and flash oreo kernel and magisk module.", wouldn´t you also need to then flash first the rooted Oreo Rom, then Kernel, then Magisk?

I want to go from ASOP-Rom to stock Oreo root, but it doesn´t work without going to stock first.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
i have flashed almost every region kdz h990ds and even h990n hk version. this method works when you have already twrp installed.

1. flash kdz through patched lg up and partition dload option. do not select aboot, aboot.bak, recovery, recovery.bak,.

2. when mobile reboots at 80%, DO NOT LET IT BOOT NORMAL, REBOOT TO TWRP.

3. Flash oreo kernel mk2000 and than magisk module, than restart the mobile.

ON SAFE SIDE, KEEP A BACK UP OF YOUR INTERNAL SD CARD ON PC.

AS FAR REGION MISMATCH, AU, ESA ,GCC,ARE, ALL HAVE cust folder having all these regions firmwares. if you still get nt code mismatch error, you can edit misc.bin to match the region you want.

not a big deal.

no need to have stock first, if you are rooted, go to twrp, wipe system and data and cache, dalvik cache, than reboot to download mode and flash with patched lg up partition dload option. in case of any confusion, do ask anytime till next 12 hours, after that, my sleeping time:D

Hi! i have already flashed this AME variant and now i think my phone lost the fast charging capability. Am I the only one experiencing this?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
This ROM does not disable fast charging. It's the stock rom and fc works fine with the mk2000 kernel.

Please note that fc is not functioning when screen is on.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
Even the lightning inside a circle in the battery icon is gone and the 'fast charging' notif also. I have already encountered this issue in rooted stock nougat and the work around i did was repeatedly reboot the device until the fast charging enables but here it doesnt seem to work. It was working in SEA variant but after flashing latest twrp and then this AME fc was missing at least for mine.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
It seems that the charging cable has issues. Have you tried it with another lg fc cable?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
Have not tried other cable, but when i connected my phone to pc it recognize the phone and i can still do backup/restore using bridge, fastboot and etc, and it is charging. Can it still be a cable problem even though it works in pc?

Update: i use my charger and cable with my co workers samsung s8 and it is fast charging.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
Yes it can. I had such a problem. But use an original cable.

I should tell you that only lg cables were compatible with fc for my v20, and when I used samsung fc cable, my phone warned me about that after 5 minutes of usage.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
I still use the cable that comes with the phone and an aukey charger. The charger and cable works fine with my co-workers s8. What could be the problem?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
That might be. Just try with an original charger and cable and see if the problem is related to them or not.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
I will consider that. Thanks for your time and help.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
i think it is kernel related issue, install kernel auditor and than check
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
I already have kernel audiutor, what should i need to check?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
fast charging option in battery section
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
That was marked check, then i tried unchecking it then reboot still the same
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
check it again and than connect charger and check the charging, otherwise it could be data cable issue too
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
Did it already, same result. I highly doubt this is a cable/charger problem since it can fast charge other QC supported phones. I am running out of options, do i need to go back to nougat? Thats a lot to do for me since i dont have the files anymore. Starting from scratch...ugh.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
if you dont mind, can you explain exact problem? because i have enabled that option, in less than 10 minutes, my phone, connected with PC usb port charged upto 10%.

i am using mk2000 latest kernel v2.0.

have you installed any other tweaks, maybe some thing messing up.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
It started losing fc after flashing latest twrp and then flashing this AME variant. Before you could see the icon and notif for fc and usually it only takes 1.5hrs to fully charge, now it takes over 2hrs. I dont use it while charging. Maybe if i have some time ill go back to nougat and try rooting again and hope fc come back.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
dear even if it takes 1.5 hrs on nougat, it is not Fast charging. Twrp has nothing to do with charging.Charging is related to charger, data cable and kernel.

if you have backup, try factory reset and than flash kernel again, and than check before installing any apps or tweaks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ogie14:
Well for me at least since my first charge it usually took 1.5hrs from 0 to 100 for fc to fully charge my phone using orig charger. Gotta try every option, thanks bro.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] albaniax:
I flashed wrong region as I had model mismatch on boot screen.

So I took correct region (SG was it), but this time I think it booted as I heard LG sound - so I definitely lost twrp. (static screen when I try go into it).

- fastboot devices doesn't recognize to flash recovery.

I just let it boot completeey, but also static screen.

This guy has it similar, but didn't work covering second screen turns, it turns completely black:

https://youtu.be/jKPS-Jzqrvw?t=73

I then did upgrade with LG UP with pre-security nougat KDZ, booted fine no static - so I start dirtysanta re-root process.

After install TWRP, last step fastboot reboot for TWRP, and ****.. again static screen?

So somehow if I re-flash TWRP, even with stock nougat, static screen problem starts & I have to 'upgrade' to Nougat KDZ again.

second screen>show when main screen on: (app shortcut)

Hi,

I managed to root with DirtySanta for H990DS and then I flashed this rom + mk2000 2.0 kernel. Rom is great, everything working great but with one flaw/bug:

I find out that "app shortcuts" from 2nd screen missing!!

they completely unavailable/missing from display>second screen>show when main screen on: (app shortcut)

list available options:

Signature

Quick Tools

Music player

Quick contacts

Recent Apps

Upcoming plans

any solutions?

p.s. Yes, I tried to reflash and same thing happening again no (app shortcut) :rolleyes: :eek:
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
Interesting... I had that issue when flashed rooted oreo SEA variant... For me it's working fine on AME.

You need to flash another Variant to see in which one you see the App Shortcuts. It's something related to the variant.

Try Indian or SEA variant.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] deffyplus:
Tnx for fast response...

Are you referring to stock kdz or rooted flashable zip?

Can you send me link, if you refering to oreo flashable zip SEA variant?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:

You can try Indian Variant. Check the first post for the link.

Or you can try SEA variant here:

Is there any possibility and significance regarding what KDZ I was used prior rooting? ( GCC	H990ds10b_00_OPEN_AME_DS_OP_1103.kdz	Unknown	2786648176	2016-12-23 )
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
I have that option on both AME and Indian variant.

I'm not sure what causes not to display it.

But you can try an Indian 10f nougat KDZ and reroot your device and flash this AME update again.

Hope it helps.

I did it in another way, flashed this https://xdaforums.com/v20/development/rom-superv20-h918-t3764390 because, this is android 7.x based rom...

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
H990 dont have anti roll back. H990N can not be flashed with ame or esa variants due to nt code mis match.

You will have to edit misc partition to change nt code, or you can only flash system keep cust of h990n.

H990n already have the latest rom, 20f. Why going for 20a of Ame or Esa
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Thanhson5075:

You can flash mobile with patched lg up, through partition dload option to keep root.

Did the TWN version of Oreo have second screen app shortcut support ?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
Yes, all the three ROMs are App Shortcuts included.

If it didn't show up for you then it's an issue with your Nougat base ROM that you have flashed via lgup.

Sometimes this bug happens and if your Nougat region be different from your Oreo region, App Shortcuts will disappear.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:
Dear i dont think so that 7.0 rom has anything to do with 8.0. When we flash with lg up or twrp, system rewrites, data rewrites, cust folder has customized apps for every region. I think that could be the issue. As far i have checked, basics are same for all regions, even for h990n, difference lies within cust folder apps.

Again it is my thinking. Have anything done regarding VOLTE on h990ds.

Do u have h918? Its cust folder and nt code information. If yes, than kindly do share, i need it for experiments.thanks

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] reza_xdv:
What you're saying is correct, but the flashable zip doesn't write to every area that LGUP writes.

That's why many people stuck at LG logo by flashing Oreo zips. For example if your factory region is AME and you root your phone using TWN Nougat then flash TWN Oreo, you'll stuck on boot. You should root your device with factory region then flash other Oreo regions.

I saw there are about 14 files that LGUP flashes and flashable zips don't. I guess they are related to gpt partition thing.

I have H990DS, with TWN Oreo ROM installed. Was AME by default.

Currently as I'm working on VoLTE thing and had progress on it, I'm using OPEN_TW overlay files and I think it makes conflict with your files as they are different in action.

If you like you can join our telegram group. The link is in OP.

Unfortunately I don't have themeing experience and I don't think I can help you with patching things. Maybe you can find people who want to help you with this in the group.

At the mean time I wanna get VoLTE to work and please accept my sincere apologies for not being able helping you with this.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hahmad78:

twrp update has nothing to do with recovery loss.

maybe you select all in partition options, recovery and recovery.bak should not been selected along with aboot and aboot.bak.

once you have upgraded to oreo, only chance remains is back to 7.0 and re root.

did you boot normal or as mobile restarted at 80%, you boot to twrp?

because i do it almost every 2nd day due to mess with system and misc.

After trying the method in this thread i didn't got it to work, kept being stuck at lg logo, tried downgrading with different version (taiwan) and then using the taiwan oreo version and still nothing. (H990ds)

When i just downloaded the AU version and did it with lgup like you described, when rebooting going to twrp, reset all besides sd-card and on the go, installed kernel and magick and it starts perfectly. So i din't use the bootable versions shared in this thread. So only i see now is the warning, but i'm already almost so used to it i would perhaps miss it :P
