For me personally nightmare its very snappy gouvernor and still great battery life

You can learn more about gouvernors with the link i posted above

Try zzmove if you dont care about performance and want to boost battery

Or if you really want to slow down your phone and get even more battery juice try concervative
[LG V20 Guides, News, & Discussion] lucfig:
My own testing has found that mpdecision and its excessive touchboosting generally do not have a major impact on battery life, and I have left it enabled in most of my kernels. In some recent devices, such as the Nexus 6 and the HTC One m9, there is no hotplugging during normal use. All CPU cores are online. It can’t be said that task scheduling, hotplugging and touchboost have no impact on battery life. They clearly do. It’s just not going to make a huge difference.

As you can see, it clearly makes a difference.

In my usage it saves a lot of battery since my usage is mostly touching the screen (games, instant messaging). Not much reading.

Besides, the interactive governor is the most balanced we've got as EAS/SCHED is not implemented. Also limiting cpu max frequency in EX Kernel Manager or any other kernel manager only works for some time, since hotplugin, perfd, etc will return to the max freq after some time.

Agreed elementalx is a legend in making battery friendly kernels and perform on the same time

If guys are interested in some good profiles for the interactive gouvernor I had some good ones with the nexus 5x

Interactive gouvernor profiles are finetuning the interactive gouvernor even more: some gave me 20% more battery on the nexus 5x

Glassfish and hawktail were good examples of good profiles

Explenation of interactive gouvernor profiles and tweaking you can find here

Can I ask after I got tarp flashed kernel and su.... What then do I flash booing?? With one one in dirtysanta folder or one o make back up on step, 3 or 4?? I'm on h990..... And also did anyone tried wets ROM.. It says works on all models
[LG V20 Guides, News, & Discussion] emdroidle:
Efforts in the direction of LineageOS are being made. I'm distinctly hopeful LineageOS 15.0 will ship for H990, we might get an official 14.1. Unsure of how that is going to play out. Getting kernel issues worked out is the first step.

Despite a number of the pieces being in place it appears not. :( May be possible in Parallels, certainly is possible in a VM. You've got rather better odds for a native port than me, I have no alternative to a VM.

Drat. I'm pessimistic about experiment5 working, but there is a chance. I'm really wondering if it is a bizarre timing quirk and Werewolf works by pure dumb luck.

h990-siminfo was really aimed at [MENTION=4549948]mustasusi[/MENTION]. The idea for h990-siminfo is to search the "misc" area for spots likely to indicate the number of SIMs. Since you're on a H990DS you would want to use "-2" instead of "-1". Information from [MENTION=4549948]mustasusi[/MENTION]'s phone is more likely to narrow the search down to a very small number of spots (ideally 1). I'm going to revisit the instructions.

Still want to track the camera focus and video recording issues down to one area. Two experimental kernels are attached. For experiment 4, does camera focus work for them that have had camera issues? For experiment 5, does video recording work for them that have had video recording issues:

Personaly i will choose werewolf kernel that had been patched by jahlex and if he patches his kernel for rctd remove, broadpwn and blueborne hack, it would be great too, for me it has no issues at all, so emdroidle can you please see what he makes to his kernel "werewolf mod" and compare your two works perhaps you will find something interesting, and can you please unlock some features for kernel tweaking, i love my phone but it can be better than that by some software optimisations and i dont have development skills, THANKS IN ADVANCE MY FRIEND.

Currenty usin jahlex version for devices with auto focus and video recording issue

tried both of your experimental kernels here is my observation

Experiment 4

Auto Focus = not working

Video recording = working

Experiment 5

Auto Focus = not working

Video recording = working

One thing i observed in both experimental kernels is that the laser focus blinks and the multi focus points becomes green but the the object remains unfocused

H990 single sim keeps rebooting to TWRP after flashing kernel and SuperSu

Hi, I have single sim H990.

I tried to root it using both v0.2 and v0.2.2 kernels and SuperSU. After installing zip files with TWRP and rebooting I persistently get a red triangle screen and then the phone boots to TWRP again. I tried a number of times starting from reflashing TWRP, but got the same result. (I've also tried to re-flash bootbackup.img before installing kernel and SuperSU). So I've got back to stock 10c version.

I'm quite newbie with this level of tools. Is there something evident I did wrong? Should I just repeat the whole process?

I've also noticed the script step3 in the set of DirtySanta files that flashes both TWRP and boot1.img. Do I understand correctly that we do not need this boot1.img? SuperSU installation modifies the boot image?

New V20 owner here! Thanks for what seems like a lot if hard work already to get this working!

I have the H990 single sim. The earliest KDZ i could find was for 31 December 2016 version 10b.

Tried the procedure and all was good until step2.bat started a process and then all CMD windows closed and the device booted into fastboot mode. With a restart, it boots to a blue error screen. I also have the garbled fuzzy boot animation.

I managed to use LGUP to restore to the original KDZ. Whats funny, is that after restoring the KDZ above to restore, the camera functions were reveres. Main sensor shows front facing image. Swiping swaps to selfie mode but shows back sensor image. Swapping between wide and standard creates an FC - need to clear camera app data to open it again.

I did the 3 OTA updates though after the restore, and all is now back to normal. That being said, I want to give root another go.

If any one who managed to root the single sim variant can tell me which KDZ they used id be greatful. The earliest I can find is 10b from 31 December 2016.

I suspect using this KDZ kicked everything out when trying too root - but im not sure!

Hum... I can but I am really not convinced that it would change a thing. The process is running but is basically consuming no resources for what I saw on my phone.

There is no best governor. The governor that will make you happy depends of your usage and what you are expecting from your phone.

Another successful H990 Single Sim root here! Unlocked bootloader and rooted with Magisk v14.

I used LGUP to drop from April 2017 security patch to November 2016 patch.

When I did this, I had to factory reset, otherwise I faced a lot of FCs.

Following this I followed the rest of the instructions, except I pulled the battery instead of "fastboot reboot" - this gave me an error the first time (not sure if it was a timing issue as I know that step is sensitive).

I then patched the system back to April 2017 using KDZwriter 1.2 (great work by the way), and flashed [MENTION=1657835]jahlex[/MENTION] 's modded kernel with camera fixes (which fixed my device not being able to focus at all)

Then, my OCD kicked in and I set on a mission to remove the dual sim details throughout the ROM. I tried to follow the instructions for "h990-siminfo.gz" you posted earlier but it didn't result in any change.

I did, however, come across this, which worked, and now my device correctly acts as a single sim H990: https://xdaforums.com/android/apps-games/app-multisim-toggle-t2830647

(this removed SIM toggles, notification SIM status for SIM 1 and "SIM 2", navigation bar button for sim swap, "Using SIM 1 to send message / call" on both SMS and Phone apps" and far more...

So, all-in-all, I have 100% working root, patched and up-to-date system (at least for South Africa), and a correctly reported single sim H990. Thank you very much!

I do have one tiny issue, but it's just a warning dialogue that I click on after it shows following a boot - screenshot to follow shortly...

Edit: Nevermind about the warning dialogue on boot, it went away following the single-sim "conversion" - this is now 100% percent. Goodbye carrier bloat! Edit 3: it's back again.

Edit 2: It seems like fast charging is not being reported correctly. The device just displays "charging" vs "fast charging" on stock. With Ampere, I can see that it fluctuates all over in terms of amperage, so it does seem that QC 3.0 is active and regulating based on screen on/off / usage etc. It hit a maximum of 1850mah (or 1950mah, can't remember) with the stock charger, so I think it is fast charging, just not saying so...

Good to hear you got it going. A few pages back with that kernel, we established that it seems to fast charge only with the screen off. For that reason I'm using the Jahlex v0.2d fix kernel and fast charging reports correctly. I don't personally mind whether it's active when the screen is on or not, as long as it's working. But I have working camera, video, fast charge and the lowest battery drain of any phone I've owned. So I'm happy :laugh:

I am using werewolf and don't experience any heat issue ... BUT I don't play. I know that the GPU is overclocked in werewolf, this can be reversed, but first we need to be sure that the problem is coming from there.

I never play games so after the first time I noticed that the phone was a bit hot I've set it to powersave and max 401MHz and CPU to 1228MHz.
