My selinux mode was already set to enforcing. I did a "setenforce 1" just to be sure, but I'm still getting the same issue with the video camera (appears to record successfully, but playback is just a still image). H990DS (SEA), V10d, Magisk v13b.

TWRP issues

Questions regarding TWRP (v.3.0.2-1):

1. When making backups, does TWRP recognizes LG-H990ds as LGUS996 (when making backup root dir)?

2. Why TWRP may show completely wrong time and date (beginning of 2016 in my case)?

3. I'd perfectly tuned 10g system but today LG started to show white system app error window with OK button:

"Unfortunately, LG System Server has stopped." The behaviour came 100% when trying to copy some text (cliptray). The only known solution (from older LG devices) seems to perform the hard reset. That's quite frightening as I don't know what exactly was the cause, thus it may reappear any moment even after hard reset. Anyone had this issue, maybe 10j doesn't have it?

4. What is the suggested procedure to restore a H990ds system from TWRP backup, what partitions and are wipes or kernel / root reinstall suggested in the same go? Is that reliable at all (I simply got boot loop today).

5. Having boot_6.bin from KDZ Extractor, would that be enough to perform rollbacks to 10b/c/d 100% from the phone µSD using the current version of KDZ Writer, is the -b flag already added to the tool or how to flash boot_6.bin boot image from TWRP?

Xposed issues... I think

After several hours I've got my phone working properly, ever function is fine. But there's still a tiny thing that isn't righ: every time I try to flash Xposed the system sorta regresses to a previous version. Let me try to explain it better, I've got busybox installed through magisk and it works fine, but when I flash Xposed and reboot, busybox is gone and xposed was never installed. Already redid the entire process multiple times and also tried Supersu instead, only landing in a bootloop on that case. Anyone knows how to fix this?

note: I've made absolutely sure that I'm using the magisk version of Xposed and busybox. This also happens with some other magisk modules like viper4android

After flashing kernel v2.4.0, the video recording works right after reboot, but after a while, it doesn't work on the default camera or the Google Camera port.

Just wanted to post this for [MENTION=8589922]xdav20[/MENTION] and anyone else who is wondering.

I've successfully used KDZ Writer to upgrade from V10F-TWN to V10J-ESA (Software version now shows as V11i-GLOBAL-COM) which as you can see, involved a region change (I live in AUS). This was done without any issues after a full TWRP backup (which I've offloaded onto my PC in case I need to fully restore my phone to the older firmware). After the KDZ Writer process I re-flashed my Magisk, Xposed, Adreno Mods, Kernel and wiped dalvik/cache and rebooted. Sat on the LG screen for about 20 minutes (thx Xposed) before going to "Android is upgrading" before finally going into the home screen. Another reboot 5 minutes later to confirm everything was working and everything is a-ok.

Only thing I've had to do is use Root Uninstaller to disable some of the Claro apps that come with this firmware (which I'm already familiar with from my G-Flex 2 days ;) ) otherwise we're smooth as gold. Looks to me like region-switching during an upgrade is supported, but it'd be best to use the instructions as in the KDZ Writer Thread OP to confirm the process would complete successfully for your phone before going ahead.

OIS is a mechanical feature; the phone's camera will physically compensate for a degree of shake/movement.

Just want to update:

Installed the Jahlex/Lexican kernel 1.2-u721-v10g over the Jahlex 0.2.3b kernel.

Everything I've tested works, AF, OIS, EIS, FM-radio & Bluetooth(both of which did not work on 0.2.3b).

It's stable and fast, no lag and no heat.

Later today I will format my SD to exfat and see if that works, currently formatted to FAT32 I believe(with a 4gb limit).

I will report back if anything comes up!

If you want to revert to stock after flashing the Adreno GPU mod due to any reason , how do you accomplish this ?

first question is -ak ok or i have to use kdzwriter -b to get the 10j?

second question is which kernel supports exfat on externalsd or do have to reformat to fat32? cant wait for the new kernel with kcal hopefully it can read exfat. thanks

thanks heaps

also wanted to know which magisk works on h990ds and do you use systemless xposed or purify system xposed?

thanks
[LG V20 Guides, News, & Discussion] Redline:
The first part is a question for the KDZ Writer thread. But if you go to the OP you'll find the -arguments you use to do the upgrade (-at or something to simulate the update and make it goes well then - a or whatever letter it is to actually do it).

Any Magisk works. Grab the latest installer zip from the Magisk thread (I believe it's 14.0arm64) and then flash in TWRP. I use official xposed arm64 for 7.0 from the thread flashed in TWRP, same as Magisk.
[LG V20 Guides, News, & Discussion] zinou213:
To all kernel developpers : first of all thank you for all hard work you are doing for us, secondly can you please update the first op with all kernel versions you've done before and make it up to date with future versions, and finally, can your future kernels be as complete as possible, in my opinion if it is possible after making a bugfree kernel, updating it with latest patches as blueborne, broadpwn krack attack fix, and all werewolf features and tweaks as gpu oc kcal and f2fs exfat implementation or any other optimisations, all these are taking a lot of time i know that, these are only suggestions from many h990ds users i know in my region and thank you again guys.

I tried to use it, but I couldn't get a signal at all... 990DS
[LG V20 Guides, News, & Discussion] hotcell:
I suspect currently there are none for 990ds ready for prime time. Anyway, why one need a custom ROM instead of just a patched stock kernel? Second screen and double SIM are rather unque features of the device, besides seems like 990 has the model differences like different partition layout and more tightened security. Stock ROM is optimized for our devices the best, everything else could be achieved as we have root access. Coming from Sony Xperia that was the case there as well.

What we need more is updated TWRP as a reliable recovery is much more important than barely usable current one with a bunch of model specific incompatibilities (starting with recognition as US996 device with wrong partition layout, unability to find out the correct time set on the device, etc.).
[LG V20 Guides, News, & Discussion] alliesquids:
What makes ASOP roms attractive to me is that they are way more up to date with security and system updates.
[LG V20 Guides, News, & Discussion] lyrical1278:
I prefer the stock look. It's all about preference. You might prefer the phone as is with the way it looks. My preference is a bit different. Of course we know there are no 990 roms ready for primetime (subjective) the phone just recently got root.

As for the stock Rom being optimized for this phone, again, from what we are hearing and seeing about battery life, that is questionable. Needs are different based on the individual. What I applaud is how devs often seek to create based on the general consensus.

https://lg-firmwares.com/lg-h990ds-firmwares/ (or the page for your model if you don't have a H990DS)

If you're on V10g-SEA and you're July 1st, I'd try a version like the H990ds10c_00_OPEN_SG_DS_OP_1214.kdz since that was only uploaded in Jan, is likely to be a version before Dec 2016 since 10c is the earliest available KDZ for the V20 (and if I recall correctly, is the one my phone came out of the box with the Dec 1st patch).

Then you can just use KDZ Writer to update to the latest (10G for your region) again.

secure start-up issue?

Hi,

Just want to start off by saying many thanks for the hard work put in to this project. I have to say, being able to root this device was the only reason why I purchased it! Phone arrived today, and followed your steps, I think all went well. I Apologise if this has previously been covered, however on start up I get:

"Secure start-up

Enter password to unlock

xx/30 attempts remaining" This happens after the lg splashcreen, but before the phone actually starts up fully. (where xx signifies how many attemps are remaining.) I've tried all the basics 0000, 1234, 00000000, 12345678, password, default_password. I have deleted dalvik/cache and data in twrp, however it still occurs. Any ideas or am I better off loading the backup and retrying? Needless to say, but I did not have a passcode/pin/fingerprint or anything set up. Thank you!
