How to determine if your G3 set up is compatible with this mod and INSTRUCTIONS and DOWNLOADS are in the 2ND post
Everyone I need your feedback with certain details which I list below in the 2nd post to be able to create an accurate list of which devices are compatible and which devices I'm currently working to make a compatible version for..
Remember always make a full nandroid backup before doing anything
I've decided to go into a little more detail in this thread to give people a better understanding of how and what this mod does, mostly by detailing how the thermal controls work and what I changed within in them. I also went into detail about governors because they go hand in hand controlling the CPU's frequency in different ways. which I'll go into more detail below in hopes of helping you understand when and how the CTTMod will improve your performance
______________________________________________
Governors and thermal control​ How & why they effect your phones performance
First here are a quick summaries of what a governor does and what the thermals do then I'll get into more detail below
Note I tried to write and explain everything as simple as possible in the hopes of helping even the newcomers to android to be able to understand and gain little knowledge and insight.
Also I hope this helps everyone also understand why and when this mod starts doing it's thing and why sometimes it might feel like it's not working and other times feel like it's working great.
There are a lot of variables and different criteria that has to be met for each process to be enacted.
The kernels governor manages the CPU's frequency mainly by the amount of load the cpu is under and other preset values.
Thermal control which determines the frequency by the temperature of the CPU and is told by preset values set in thermal files when it (cpu),should lower its frequency depending on temperature
Both play big rolls in how well your phone performs but in opposite ways the governor basically start out by trying to keep your phone running smoothly by increasing the clock speed to match the load on the cpu, whereas thermal control does the opposite where it kicks in after the cpu reaches a preset limit and starts lowering the clock speed in an attempt the cool down the CPU to keep the phone running smoothly
Now the governor bases what the clock speed is set to and determines the point the kernel will increase the CPU's frequency by the load value set in the governor which is preset by the OEM or dev. With a rooted phones most of these values can be changed. The load values based on numbers with 0 being the phone just sitting idle not under any load so the governor will have the cpu frequency set to the preset minimum allowed frequency set by the kernel. And as the work load increases the governor raises the frequency in steps also preset by the governor until the CPU reaches a frequency that handles the increase in work load and continues to raise the clockspeed as the load increases. Now once the CPU's load reaches the preset target load value it will be running at the maximum allowed frequency set in the kernel. Different governors have a different numbers of load and other settings some can be changed and some can't depending on the governor and what features were added by the builder
For example the conservative governor sets it's target load values high usually around 95 and a step value of say 14 (step value being the amount of frequencies it will go thru to reach the maximum set frequency. Which helps improve battery life but you sacrafice performance. As say the interactive governor with the target load value set at 70 (Target load value being the highest amount of work load on the CPU before bumping it up to the maximum allowed CPU frequency set in RJ kernel and a step value of 7 will have better performance that the conservative .
All but one governor (performance) which is set to run at the maximum CPU frequency all the time) has parameters that can be tuned to your liking with one of the many CPU/kernel control apps out. But not all kernels and the governors come with the same settings. The builder/OEM/dev. of the kernel can pick and choose what features and governors to put in the kernel and also what settings are allowed to be changed. Also not all particular governors come with the same allowed settings. One developer might only put in the interactive governor and only put a few settings that can be changed whereas a kernel from another developer will add in every setting there is for the interactive governor.
Here's a great page explaining just about everything you should know about governors it's a must read.
http://forum.xda-developers.com/gene...ors-o-t3048957
OK now thermal control works by throttling the CPU down to preset frequencies at preset temperatures and is also done in a preset # of steps. Thermals also monitor and play parts in controlling other components like the GPU, battery and a couple of other things.
First let me be clear about one thing
The CTTMod does not turn off thermal throttling. Now the trick of going into the hidden menu and turning thermal mitigation and thermal control on. That does turn off all thermal monitoring and control and I highly advise against ever doing it. You take a huge risk of frying your phone.
Now let me explain a little what gets changed by installing this mod, and how and when the thermal control do there thing.
What i did is changed the first 3 bump downs (steps). I did this raising the preset frequency in the phones thermal file that tells the CPU to slow it's clockspeed down when the cpu reaches a preset temperture. Now in reality the thermal just sits and monitors the temperature of different components. It doesn't affect the CPU at all until it reaches a preset temperature.
Now there are 6 steps 5 of which throttle your cpu down. The first one being you CPUs max frequency and as long as the cpus actual temperature is below the one predefined in the file the CPU is allowed to scale as high as it needs to in order to complete the task in an efficient and speedy manner. So until it reaches that temperature it's the kernels governor that is deciding what the CPUs frequency needs to be by the load that the CPU is under at any given time. Now each different governor has its own way of how and at what load points it'll tell the cpu it can scale up or down by the values set in parameter settings of the governor and also tells the CPU how many steps ( scaling frequencies) to go thru and how long to stay at each step before moving on. So in short but not the entire story is that the governor controls when to speed up the cpu by the load it's under and the thermal controls tell the cpu when to step down to certain frequencies that corresponds with temperature points that are set in the thermal file in an effort to keep the temperature of the CPU down to try and keep the phone running smoothly and within an efficient operating temperature
Now what I have done is raised the first 3 points at which the thermal tells the cpu to be at. But left the last two and the shut off values at their stock values so it doesn't let the phone get hot enough to burn up. That's why you might notice with this mod after a long period of time using your phone under heavy load and the cpu reaches that forth step down temp. that when you'll notice a dramatic slow down. The thermals also control a what i would consider a fail safe temp setting that will automatically shut your phone down. Which is set at 120°c and won't let you turn your phone back on until the temp lowers to 115°c which I also left at the factory settings.
Now hopefully after reading this you have an understanding of what the mod does and how it affects the performance of your phone. And how the settings in whichever governor you are using also affects the performance of the phone. So if your governor is not tuned to your usage. You will not see a difference after flashing the CTTMod.
Now I'll explain what changes I made to the first bump down to. I changed the first frequency bump down to 2.26 and raised the tempurture it has to reach to 70°c Stock was set to drop the cpu down to 1.5 GHz at 60°c
Now at stock they scale your clockspeed by almost half of the processors actual top speed of 2.45 ghz which is why the g3 has such bad lag when after a short time of moderate to heavy use. So as a result of increasing the first set frequency to 2.26 GHz and raising the temperature limit will allow you turn operate you phone for a much longer period of time before you start to notice the phone slowing down .
Also in the LP versions I was able to tweak some of the battery values to keep the phones temperature down which I had discovered by accident and for most people they say there battery now stays cooler compared to stock. And tweaked the GPU. The second version that is now up implements the cpu throttling and battery improvements and I hope to hand the GPU tweaked and working in the next version.
I Hope this has helped you have a little more insight on what this mod does and how you devices improvement might not be noticeable compared to someone else who show a great improvement in performance. It all depends things we do to our phones to customize them .ie different ROMs kernels, settings and mods we add to them.
Let me know how the mod works for you and what carrier version and ROM and kernel you are on and governor being used
Thanks Rob
Also with the vs985 MM firmware the thermal file in system/etc is thermal-engine-8974.conf
So check to see what thermal file/s you have. If they're different send me a link to your thermal files and I'll take a look and see what I can do modifying them

Instructions and Downloads for G3 Marshmallow
Instructions
#1 - DO A FULL BACK UP BEFORE YOU DO ANYTHING
And since I only have access to the vs985's 46a stock firmware (MM) That is the only variant I can actually test myself . So far haven't found a device that's not compatible
Any g3 variants that have different files the just the one I name below I will need you guys to post me the information and file/s that I have listed at the end of the instructions
First you have to determine if your phone and ROM are compatible.
Check your Roms thread op and see if it's already included in the ROM as many Roms have now included the CTTMod
So before anything, you'll have to see in you have the file named
thermal-engine-8974.conf.
To do so navigate to /system/etc and look to see if you have the file with the same name as I just stated above. If you see that you have only one thermal file and the names match,
Then follow the New Instructions- First still follow the instructions in op to see if your variant or ROM is compatible then proceed
1- reboot into recovery
2- flash mod
3- wipe the cache important no need to wipe dalvic, but you must wipe the cache for the mod to take into affect.
Then in your kernel control app. In thermal make sure it's set to core control.
Now this is optional but under cpu hotplug turn mp decision/intelliplug to off. With hotplug off it will throttle less or on to throttle faster but both ways it'll only throttle to 2.26ghz on the first bump down instead of 1.5 or 1.7. You can read more about mp decision and intelliplug and how they affect the mod HERE
If you decide to leave feedback, good or bad you must include the details about your phone I have listed here
starting with your G3 model # The type of ROM (ie stock, aosp or cm, whether you on a stock or custom kernel, and the governor you are using.. Also please leave any results you have based on one of the two ways below on how to evaluate whether or not the mod works as it's intended too and just how much of an improvement you notice
First and easiest way is your actual user experience. Use your phone like you would on any given day and try to remember things you been doing on you phone that caused your phone to feel slow , laggy , not as responsive, or made your phone get hot to the touch. . Then install the mod and try to repeat what you did before and feel the difference.
If you'd like to take it a step further for some real evidence on if it's working or not. You can do some real testing by
First you'll need an app like CPUtemp to see the CPU frequency, load it's under and the temp of the cpu in real time .
With your phone fully charged use it moderately like going on Facebook and making a call have 2 or 3 apps going at once and doing something on the phone. For around thirty minutes. You want to put the cpu under at least 50%: load logging the temp and frequency every couple minutes for about twenty to thirty minutes. Then do the same again but this time you'll want to put the cpu under a heavy load 100% really work it.(running alot of apps, playing a resource hogging game, running a benchmark or stability test I think you get the idea)
Log the temps and CPU frequency again every couple minutes for 20 to 30 minutes or as long as it takes to reach full load
Then repeat the process after you install the mod.
You should perform the tests once before you install the mod logging the results and then try to duplicate what you did the first time after you install the mod and log the results. It's important to do some testing before you install the mod to give a baseline to compare with. Then you will be able to see what did or didn't gain any improvement compared to stock. And if an something got worse I'll know where to look to fix it.
Thank you as the more people willing to do the testing and share the results will help me greatly on improving, perfecting and to trying to make it compatible with as many variants and ROMs possible.
DOWNLOADS (Alternate download links bottom of this post)
G3-CTTMOD-MM_final:
Yes this is the same mod I had posted in post 52 I've just now made it official after having tested it for a while now.
As stated before I will still be updating as I see fit
CTTMod-MM+FC-v2
Change log: increased the charging voltage by 50mv on the second and third bump downs. Left the first and forth and fifth stock. Goal is to to speed up charging times. I only increased it slightly to start so there might not be much of a noticeable difference. Will increase more once some testing has been done on this one. Please leave feedback thanks
CTTMod-fc-V-2.1 - changes - increased the second and third charge by another 50mv and still left first, forth and fifth stock the same as v-2
CTTMod-MM+gpu-v3-beta
Change log: added slight increase in GPU
CTTMod+fc+gpu-V.3.1- change log- goal better GPU performance along with the faster charging from v2.1
Back to stock zip
( I haven't personally tested this but I don't see any reason why it wouldn't work)

Test versions
I'm going to work on posting all my test versions here as I have many improvements I'm trying to make but can only do and test one at a time to make sure the changes are doing what I want them to do. So please if you decide try a test version please message me with your findings and how you tested
Remember any of the mods posted here are experimental and have not been tested as with anything you flash this at completely your own risk
Here's the first test version for better gaming
CTTMod-fc-gpu-v4
Please lane feedback

check your file/folder permission though, this is what I got even I am logged in
access denied
looks like you don't have permission to access this folder. Make sure you are signed in to an account that has permission, or check with the developer to request access.
PS: Also, the link should be www.androidfilehost.com/?fid=xxxxxxxxx (17 digits ) , but yours is androidfilehost.com/user/?w=settings-dev-files&flid=49846

Instructions
First thing since I only have access to the vs985's 46a stock firmware (MM) and won't flash an asop MM ROM until I have this just have I want it and it all backed up to my computer.
So before anything go to /system/etc and find any files with thermal or thermald in it. Hope you only have 1. Named thermal-engine-8974.conf if that's the only file you have you can just flash the zip wipe the both caches reboot and give it about a day to settle in before starting to test or give any opinions
Now if you have different files then the one I name above send all the details about what's running on your phone and upload a copy of whatever files you have and send the link along with you phone info

I'm on fulmics 3.5 with solid kernel (d850). I don't see any thermal file in my system\etc folder. Can I still flash the mod?

EDIT SORRY MISREAD you're right in the /system/etc/ there and definitely a thermal file in there
near the bottom
File is. .config or you might been on a romv with a thermal. XML file or similar
Dump question but you're using a root file browser

Second version on the way
I started on the second version last night in hopes of keeping the phone cooler at high loads compared to stock ) like I did with previous versions). So after my initial real feel testing for the first few hours after flashing the the new mod I was happy to feel that the phone felt cooler and didn't lag at all and just felt very smooth even after am hour of moderate to heavy use. I was happy enough to say f-it and go against my own rule of testing and just waited a few hours to let the phone get back to normal temps and than I started an all it assault on the CPU for about thirty minutes straight I kept the CPU under 100% load or as close as possible for the entire 30 minutes. Well the results were better than I hoped for. The highest temp the CPU reached was right around 80° c and was there for only a few seconds and throttled down the CPU just that time and cooled down enough to throttle back up in less than a minute. Now compared to stock. And doing pretty much the same tests for the same amount of time stock went as high as 100°c and throttled down to 1.2ghz within the first ten minutes then down to 1.19 after 15 minutes and stayed between 996 and 1.2 the rest of the time occasionally dropping lower. By a little over halfway testing it stock without the mod the phone was at a crawl and by the end I thought for sure it was going to shut down.
Now with the mod installed it only throttled down once maybe twice but never lagged and ran smooth as silk the whole time. So I think I'm happy enough to try and release it tomorrow as version 2 experimental just in case I find a bug or something in the next few days if i don't then I'll post it in the op. continue testing it and start on the next version which hopefully I can make it as good as possible and achieving what I wanted to do with this mod, but there's always room for improvement. Well below I posted a screenshot of cputemp which was taken at around the 28 minute mark into the test and it shows the load the CPU is under, the frequency it's running at, and its temperature . now it doesn't really refect the average temp or average clockspeed which was closer to 70°c and 2.26 ghz because it bounces up and down quickly. That's why you need to check the reading alot because of how fast and how much all the different readings change every few seconds. So to get a more accurate average of the readings you need to log them as often as possible with whatever app you're using to see the temps and frequency.. Like in the picture I caught it at a much lower frequency than the average which was around the 2.26 mark and spending almost the same amount of time at the top speed of 2.45 ghz . one other bonus I noticed is how low the battery temp stayed. I don't think it ever went above 36°c and remember I had the on charge the entire time.
And these results should improve over the next few days as the mod has a chance to settle in. Hopefully users will get similar results and post them to confirm my results.
I'll perform the tests again in a few days and post them hopefully they improve
