Thanks for your time. Yes, I also tried this metod with patched lgup and regular 1.14 + with uppercut. Without luck. Model is unknown.

https://ibb.co/f7DNOw

I also try to set com port as COM41. In device manager, my phone is reconized as "LGE Androidnet USB serial port" I try with lgup, bridge, lgflashtool. Only thing I didnt try is KDZ writer, but I don't have fastbootm so I can't try this metod.

https://ibb.co/i4vDVb

I read pages before and try a lot of this metod's, but without luck. The biggest problem is than I don't have any kind of support in my conutry because this model is not for Europe, so no one can't repair my phone, even the services with octoplus box (they says: this model is not on my list), Any advice is helpful :) Thanks

Spent 50 days to read all posts about v20.

Bought v20 h990ds in india.

Followed word to word instruction to root it.

Was successful to root it.

Used it for 23 days with root and xposed. Suddnly while playing with tasker network connection was lost.

Was panic, but flashed stock back, but still no network.

Tried 3-4 stock roms before dec and april.

Baseband is there IMEI is present. Can turn data on/off.

But sim is not detected. It detects in other mobiles.

Stressed since last 4 days.

Any help would be appreciated.

PS: Read all post and root worked for 23 days.

Tried all possible way to fix network issues. (Formating modem, fastboot option, writing imei, still have root and recovery installed.)

Did you try another sim card ? Even if youts is detected in another phone, I would try to be sure this not the cause of your problem...

Who is so gentle to write step by step for using Kdzwriter of [MENTION=6984210]emdroidle[/MENTION] and upgrade a root LG V20 from 10c to 10g ? Iìve read his instructions but i am unable to understand how to do it, thank you in advance
[LG V20 Guides, News, & Discussion] alldine345:
its quite simple actually. assuming you already rooted using tutorial on page 1, i assume you already had

a. adb fastboot tools on your pc

b. KDZ files for updating your rooted phone

the proses is simple as :

a. copy KDZ files to your sdcard. its better to renamed it for easier instalation, like UPDATE.kdz or whatever suits you

b. download kdzwriter-1.2.gz and paste on your adbfasboot tools folder. optional, change it to kdzwriter.gz for easier process

thats the preparation, now start updating :D :

1. boot into twrp-swipe for allow modification-connect your phone to your pc/laptop

2. open powershell/command prompt on your adb fastboot tools and enter this

adb push kdzwriter.gz /

3. type " adb shell " and then type this command one by one ( dont forget to press enter after each command)

gunzip -c /kdzwriter.gz >/sbin/kdzwriter

chmod 755 /sbin/kdzwriter

umount /system

ln -s /sbin /system/bin

4. did you remember the KDZ files you put on your SDcard? now lets use that baby to updating your phone. type this :

kdzwriter -a /external_sd/update.kdz

5. after done, unplug your phone and while still on TWRP reflash your kernel and Su method and reboot. done!

nb: my english suck, deal with it :p

did you already put your KDZ files to sdcard? and did you already rename it to update.kdz?
[LG V20 Guides, News, & Discussion] brunochka:
Yes, sure, it's on main directory of SD Card and name update.kdz, shall i enable USD Debug maybe? When i reboot in TWRP the phone and i connect it at PC shall i do anything in TWRP or nothing? I've TWRP 3.0.2-1
[LG V20 Guides, News, & Discussion] alldine345:
like i said before, if you already rooted using page 1 tutorial usb debugging should be enabled on the first place. you dont need to change anything on TWRP only need to swipe allow modification if you get warning when entering TWRP. make sure your KDZ files arent corrupted. recopy or redownload again. in TWRP you could select Mount and enable MTP then recopy the KDZ files to your SDcard

USB OTG Problem

[MENTION=6984210]emdroidle[/MENTION]

I have found a reproducible USB OTG fatal error with 10f ROM on ds v0.2.3 kernel. I'm not 100% sure when this problem was introduced and unfortunately in my last tedious last tests I never tested the screen off scenario that I was aware of.

The Symptom:

While the phone's screen is off plug in an USB flash drive (mine is formatted exFAT). Three possible things can happen namely, screen is turned on and you are good to go, screen is not turned on but when you do it manually everything is okay, or the phone becomes unresponsive for which you have to pull the battery out eventually. From the past experience and previously mentioned, an error screen would be eventually displayed if you wait long enough.

I'm going to run kdzwriter again with -as flags to make sure kernel modules of stock ROM are up-to-date with 10f without touching anything ds v0.2.3 may have added, as per description of -s flag.

Booted to TWRP, wiped ART cache and Cache folders, made a backed up. Decided to reboot the system to move the .kdz file to the root of the SD Card as I forgot to do it. Upon the reboot I got a kernel crash. Took a screenshot by my other untouched H990DS. As you can see the error messages are riddled with exFAT references. Pulled the battery out and turned the phone on again and it took ages to read the SD Card which made the phone almost unresponsive. The SD Card is Fat32 formatted. Rebooted the phone again, and this time apart from a lag that I did not observed before everything else seemed normal again. Going to post this now and will come back with kdzwriter -as results when is done.

One thing I forgot to mention before, since my last post I discovered over 20GB of junk data in LOST.DIR folder of my SD Card which must be caused by all the problems I have reported so far.

[MENTION=6984210]emdroidle[/MENTION] just before I submit this post I noticed in one of the last lines in the attached screenshot says kernel Panic, something I recall from your kdzwriter page.
[LG V20 Guides, News, & Discussion] brunochka:
[MENTION=3868643]alldine345[/MENTION] Thank you so much, i just clicked in TWRP in mount option system that was unchecked, redone everything, renamed my 10g Kdz file into update.kdz on Pc before transferring it to Sd Card on Lg V20 and finally i got it, i have received advise from Kdzwriter to reflash kernel so i reflashed werewolf kernel v0.1 and SuperSu too now i am with 10g and security patch 01 July 2017 and ROOT !!!
[LG V20 Guides, News, & Discussion] xdav20:
There are two parts in using kdzwriter namely, installing it and running it. I can help you a little bit with installing it, the way I do it.

1. Make sure you can work with adb by turning the usb debug mode on, connecting it to your working pc, and can see your device after executing 'adb devices', without the single quotes.

2. Copy the .kdz file to the root of your SD Card and rename it lg.kdz for making less typos in TWRP's terminal

3. Boot to TWRP, while USB is connected to your working pc, and tab on Advance option once TWRP is loaded

4. From the TWRP's file manager copy and paste the version of kdzwriter.gz you intend to use to the root of your device. Basically, where you cannot go up any higher in the file manager.

5. Open a terminal command window in your working pc and type 'adb devices', without single quotes, to make sure TWRP can receive commands

6. type 'adb shell', without single quotes, and do the adb shell commands as per instruction, the gunzip, chmod, umount, and the link thing. Don't worry about umount error, any other error will be far important

7. Go back to TWRP and in the terminal run kdzwriter, kdzwriter-1.1, or kdzwriter-1.2, depending on which version you are using, with the right flags and the path of your .kdz file. It would be something like /external_sd/lg.kdz

Last thing... make sure your antivirus is disabled when working with adb.

Good Luck!

USB OTG Test Results

[MENTION=6984210]emdroidle[/MENTION]

Ran kdzwriter with -as and this time decided not to reflash the ds v0.2.3 kernel to see what happens. Rebooted system. Obviously, got back all the system apps I removed before. Rebooted again before testing USB OTG scenarios. Obviously because all system apps are back I noticed lags. While screen is on, plugged an USB Drive and all is good. Rejected and replugged in while screen still on and all is good. BTW, root has remained intact. Turned the screen off by double tapping, and inserted the same USB OTG drive and cable, the screen remained off which means problem. Waited until I get the error screen which happened to be green instead of yellow that I previously mentioned. I took a screenshot by my other H990DS, unrooted, phone and in order to copy it to my other phone, that I use to write and post these reports, I switched the screen off and plugged in thr very same USB Drive and the screen turned on and good to go. I attached the new screenshot.

Either kdzwriter causes this issue which means anyone used -a, -aM, and now -as is prone to this issue or the rooting process does this. Going to reflash ds v0.2.3 and do another test before submitting this.

Something interesting happened, after flashing and a reboot while the screen was on inserted and rejected the USB OTG twice without any issues then double tapped and turned the screen off and inserted the USB Drive again and the screen turned on and all is good, not expecting that. Then turned the screen off, same method, and while was off reinserted the USB Drive again and got the green screen again.

While I was flashing the kernel, I recalled how many times I read the Fast Charging is enabled only when the screen is off. I thought my 2nd H990DS, 100% stock and untouched, can be used to test it. The fast charging while screen is on is supported out of box, please see the attached screenshot. Then decided to test it with my rooted H990DS and it is supported too. Please ignore this part if I misunderstood the fast charging topic going on in this thread.

Edit-01

Flashed jahlex>werework v0.1 with camera fix and did the very same USB OTG scenarios and I can confirm nothing crashed. Then flashed ds v0.2.2 and kernel crashed upon screen off insertion.

My opinion is, exFAT issue is with kdzwriter -aM flags that can be fixed either by -a or -as but USB OTG screen off issue is with [MENTION=6984210]emdroidle[/MENTION]'s kernels (v0.2.2 & v0.2.3) that I just tested.

[LG V20 Guides, News, & Discussion] JJJRW:
1) does the OIS work on our phone after root? As i got video stabilization as false in device info app. Refer first screenshot with the round circle.

2) i used device info hw app and got the camera module names whose screenshot i have attached. Imx 219 on google brings back result for sony 8 megapixel camera. And imx 298 brings back result for 16 megapixel camera. The. Imx298 is also used on the oneplus 3 so we may get help from there for compatible drivers as both have snapdragon 820.

Just so you know focus works fine on my device but video recording doesnt.

Just tryna do my bit for this thread. Not very good at giving any info but good at following stuff.

There is also a list of drivers installed on the device if anyone wants screenshots for reference then comment please.

LG H990DS finaly fixed!

Hi to all, I am trying 3 weeks to fix my phone with all posted metods. I read a lot of experience on XDA and find a member who's fix my hard bricked device. He is in Vietnam, I contact him and he told me to downlad his remote app on my PC. I download it, and he is connect to my PC. I put my device on download mode and wait. Phone is reboot half times, show red triangle and after about hour and half, he says to me: now you can flash firmware with LGUP, your phone is fixed. I write new modem to your phone. When I connect it to LGUP, phone is reconized! Now I finaly have fixed phone after 3 weeks :) If anyone have same problem, you can google this guy (or search it on facebook, I'm send him PM od messenger): "Vũ Ngọc - Mobile"

It is not my intention to advertise a man, but I believe that this is a very important information for all those who no longer have an exit. Thanks to all those who tried to help me these days. I believe that this commendation to this humble man will bring you a donation coin, and you will fix your phone without much trouble. A lot of regards!

My 2cent

[MENTION=1536807]developers[/MENTION]

I have a theory as to why the new main back lense camera in H990DS has two drivers namely, imx298 (Sony) and s5k2p7 (Samsung?). This is because in snapshot mode one designated driver is used i.e. s5k2p7 and in video recording the other. From user reportings, it appears both drivers do well in snapshot mode but only one would work properly in video recording mode.

I think the code that needs to switch the driver for the right mode is either missing, incomplete, or written incorrectly.

By the way which version of kernel did you flash?

I suspect, this issue is due to baseband as the version of baseband in my phone is different than yours.

Can someone confirm that network issue has anything to do with kernel or stock version.

I have two questions, but they're not related to this thread but as there're more active users, so I'll ask here.

1.How can I change dpi without affecting the second screen? I mean when I use wm shell, it doesn't work properly, some items showing incorrectly. Also changing build.prop density value will move some part (status bar) of the main screen to the second screen. Is here another way to avoid this?

2.How to change navbar icons? I used xsnata, but it impacts on performance and causes huge lag in the system. Also substatum doesn't work. I tried some other apps and xposed modules, but with no success. Do you have any idea?

[MENTION=286591]speculatrix[/MENTION] Yes sure and it works perfectly with KDZ Writer tool, i have root and i am with security patch 01 July 2017
[LG V20 Guides, News, & Discussion] interruptingcow:
I just wanted to check please before I proceed. I have unlocked bootloader etc. on Samsungs but this is my first attempt at LG and the terminology is somewhat different. I have H990DS V10g-SEA-XX. So...

I followed the instructions on the first page and while using dirtysanta I got an unknown package error, so I went back to step 3 (refurbish). So from reading the many threads after is this correct?

1. Assuming step 3 means before 31/12/16. So looking at lg-firmwares.com I can not see an SEA version for 2016, only 2017. Should I use the TWN version instead (H990ds10c_00_OPEN_TW_DS_OP_1214.kdz)? Or the AUS version (H990ds10d_00_OPEN_AU_DS_OP_1216.kdz). I am in UK if that makes any difference at all.

2. Once I have firmware do I use refurbish or upgrade (I tried refurbish on 10g firmware and it failed, but this was trying to flash same firmware as was on the phone already)? What does refurbish actually mean and what are we trying to achieve? Is it just to downgrade the security level to allow dirtysanta to work?

3. When I click on the BIN file in LGUP it asks for a .tot file, but I am supplying a .kdz file. Is this correct?

4. Once I have completed the bootloader unlock etc. I should be able to use KDZ Writer to bring the software up to date and have all the latest features.

I know these have been answered a dozen times in this thread but I just wanted to double-check before I brick my phone due to a lack of understanding of what I am doing. Thanks all.
[LG V20 Guides, News, & Discussion] brunochka:
[MENTION=7380129]interruptingcow[/MENTION] important is that you downgrade yr firmware installing one with patch security of December 2016, then on LGUP you click on upgrade (not refurbish), obviously you connect yr LG V20 in download mode and very important then after 'downgrading' it, make then at first start a factory reset.

in LGUP you just insert the kdz file, nothing else...

After having it with root then you can goahead with Kdzwriter, and have it 'updated' to latest security patch and firmware :) i've again 10g with patch 1 July and root :) ! I flashed werewolf kernel, all works, fast charge, autofocus, no freezing video!

To root it follow [MENTION=6984210]emdroidle[/MENTION] steps (very important to have disabled the antivirus on PC!!)

Got it working. looks like I had the wron common.dll. I thought I downloaded the correct one. I found apost to extract it from the .kdz. So... on I go with root. So exciting!

hmm... now failed on step 11

Using dirtysanta's steps: Run "RUNMEFIRST.bat" <-- Do not close.

Run "step1.bat" <-- Wait until you can type something again.

Type "run-as con" <-- If you get unknown package error, means your latest security patch patched it out; go back to step 3. LGUP should be able to downgrade you to an earlier firmware update.

Type "chmod 0777 /storage/emulated/0/*"

Open Terminal Emulator, Type "id"

Look for something containing "untrusted_app". If not found, Start all over again. If found, continue.

UPDATE: back on track - I used a different terminal emulator. On to step 12...
