I really cant understand how to configure setcpu properly. Ive a rooted legend on 2.2 , 3.15 build. My doubts are:
1.What is userspace, ondemand and performance scaling ?
2.On the main menu of the setcpu if slided the bars way down to 19 max and 19 min , but it still shows 600max 480min as default as the speed ...
3. What does the "set On boot" option do ? Set the values on the sliders after booting ? But that does not happen.
4. I also want to overclock my legend. After installing the kernel , is it so that that the sliders' max value will increase ?
5. Also what is the difference between the 3.5 and th 4 kernel version and why do people recommend the 3.5 version ? (btw i wanna oc to 768)
-e-
My 2nd query is solved. i disabled the perflock and it went according to the sliders. But please explain the differences between userspace , performace and ondemand scaling
Any help guys ?
its easy, set on boot means what it says.
select autoconfig or recommended
drag slides to max speed and lowest speed
triggers are such as if the battery goes below say 15% it will lower the speed

sorry forgot to mention that performance keeps it at the max speed and on demand keeps it at lowest speed until more is needed

Many of us don't know what is CPU Governor's and which suites them perfectly, so after doing some Googling i am writing these.
What is a CPU governor?
A CPU governor in Android controls how the CPU raises and lowers its frequency in response to the demands the user is placing on their device. Governors are especially important in smartphones and tablets because they have a large impact on the apparent fluidity of the interface and the battery life of the device over a charge.
NOTE: You cannot change your CPU governor unless your phone is rooted and you have a ROM or app that lets you make a change. Also, different kernels (the intermediary software between your phone's hardware and the operating system) offer different sets of governors.
S/W or App's for using these features:
1. SetCPU.
2. No-frills CPU.
3. Tegrak Overclock.
1. Smartass: Performance is on par with the “old” minmax and smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 it will cap it to your min frequency).
2. SmartassV2: Version 2 of the original smartass governor from Erasmux. Another favorite for many a people. The governor aim for an "ideal frequency", and ramp up more aggressively towards this freq and less aggressive after. It uses different ideal frequencies for screen on and screen off, namely awake_ideal_freq and sleep_ideal_freq. This governor scales down CPU very fast (to hit sleep_ideal_freq soon) while screen is off and scales up rapidly to awake_ideal_freq when screen is on. There's no upper limit for frequency while screen is off (unlike Smartass). So the entire frequency range is available for the governor to use during screen-on and screen-off state. The motto of this governor is a balance between performance and battery.
3. SavagedZen: Another smartassV2 based governor. Achieves good balance between performance & battery.
4. Ondemand: which would instantly go to max frequency once it detects cpu activity and then scales down as the requirement decreases.
5. Performance: It has the same min and max frequency so I guess your phone will heat up and throttle really quick, although if you want to benchmark this would give you the best result.
6. Interactive: Much like the OnDemand governor, the Interactive governor dynamically scales CPU clockspeed in response to the workload placed on the CPU by the user. This is where the similarities end. Interactive is significantly more responsive than OnDemand, because it's faster at scaling to maximum frequency.
Unlike OnDemand, which you'll recall scales clockspeed in the context of a work queue, Interactive scales the clockspeed over the course of a timer set arbitrarily by the kernel developer. In other words, if an application demands a ramp to maximum clockspeed (by placing 100% load on the CPU), a user can execute another task before the governor starts reducing CPU frequency. This can eliminate the frequency bouncing discussed in the OnDemand section. Because of this timer, Interactive is also better prepared to utilize intermediate clockspeeds that fall between the minimum and maximum CPU frequencies. This is another pro-battery life benefit of Interactive.
However, because Interactive is permitted to spend more time at maximum frequency than OnDemand (for device performance reasons), the battery-saving benefits discussed above are effectively negated. Long story short, Interactive offers better performance than OnDemand (some say the best performance of any governor) and negligibly different battery life.
7. InteractiveX: Created by kernel developer "Imoseyon," the InteractiveX governor is based heavily on the Interactive governor, enhanced with tuned timer parameters to better balance battery vs. performance. The InteractiveX governor's defining feature, however, is that it locks the CPU frequency to the user's lowest defined speed when the screen is off.
8. Pegasusq: The Pegasus-q / d is a multi-core based on the Ondemand governor and governor with integrated hot-plugging.
Ongoing processes in the queue, we know that multiple processes can run simultaneously on. These processes are active in an array, which is a field called "Run Queue" queue that is ongoing, with their priority values arranged (priority will be used by the task scheduler, which then decides which process to run next).
To ensure that each process has its fair share of resources, each running for a certain period and will eventually stop and then again placed in the queue until it is your turn again. If a program is terminated, so that others can run the program with the highest priority in the current queue is executed.
9. Abyssplug: from what I have read is a modified hotplug which is simillar to ondemand but has the ability to turn off a core when it is not needed and is a little more precise in scaling down cpu performance.
10. Lazy: This governor from Ezekeel is basically an ondemand with an additional parameter min_time_state to specify the minimum time CPU stays on a frequency before scaling up/down. The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand. Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state on a step overriding sampling interval. Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always select the maximum frequency while the screen is off.
11. Powersave: This is opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.
12. Lagfree: This is similar to ondemand. Main difference is it's optimization to become more battery friendly. Frequency is gracefully decreased and increased, unlike ondemand which jumps to 100% too often. Lagfree does not skip any frequency step while scaling up or down. Remember that if there's a requirement for sudden burst of power, lagfree can not satisfy that since it has to raise cpu through each higher frequency step from current. Some users report that video playback using lagfree stutters a little.
Now you decide it on your own which will suite you ....
Hope this helped you .......

These Governor's are related to Kernel, when Kernel is developed these will be coded into kernel and we can select them by using App's like "Set CPU" or "No frill CPU".
"No frill CPU" is free and similar to set CPU...
Eg: In Horsepower kernel developed by fuss132 for Galaxy R we are having most of these Governor's...

As rhodrhi said you can try abyssplug or Powersave ( I forgor about this i will add it to OP) and Under clock the CPU will save some power....
Eg: When screen is off i will set it to max 780 and min 256 ( Presently i don't have mobile with me so i don't remember exactly the frequency's)....
Can some one tell me how the lagfree governer works on sgr? I am actually getting good smooth response on this governer and also it does not eat too much of battery...
How about others?

How does DEEP SLEEP mode play into all of this?
Does this governor prevent DEEP SLEEP when the phone screen is off since it locks it at the lowest speed?

Deep sleep is basically your phone going into a low CPU state and it's most likely enabled in all the kernel's by default irrespective of all Governor's ....
Install the app CPU Spy which will let you know the Time spent in each CPU frequency including deep sleep also....
Thnx

Thanks man this helps me understand a little ore of configuring a nandroid. :highfive:
Hello,
Let me introduce a kernel that I've been using every day. Despite the name which is me, the actual developer of this kernel is aatjitra, so please thank him. Since he is using N7105 and for ease of reports, we decided to make a separate thread for the International Samsung Galaxy Note II GT-N7100 model. So it is me that will maintain this thread for N7100. Of course with the help of him to answer questions.
For GT-N7105 model, please visit the original thread here
* WARNING *This kernel is only for stock ROM or TW Based custom ROM!DWYOR - Do With Your Own Risk!!!
TerraBuzz kernel is created for Samsung Galaxy Note 2 that will suits daily usage. There is no cutting edge and fancy development for this kernel as it's made as close as stock kernel based on source code provided by Samsung. Only cherrypick modification/enhancement from other developers to be implemented in this kernel. This kernel is fast, stable, and battery friendly. All tweaks and modifications are carefully tested to ensure great performance without compromising Galaxy Note II standard features.
Some unnecessary debug and log is also removed to make this kernel as light as possible.

Install it using your preferred custom recovery
Reboot the phone
Enjoy the smoothness!
If you're coming from previous version (ex: PR2.5 and up):
- Open STweak and go to 'Extras' and tap 'Reset settings to default'. The apps will close by itself and let it be.
- Open Root Explorer or any file explorer with root access, go to folder /data and delete the folder .terratweak
- Download kernel that match your device type and save it to internal/external storage card on your phone.
- Flash the kernel via TWRP or CWM.
- Reboot and let it stay for a while or until the icon 'checking sd card for error' is gone.
- Open STweak and now you will see a control tab for SCREEN

Screenshots
Here are some screenshots collected from some of our users in the development of this kernel using various ROMs. Please use it as reference only, actual experience and results may differ.
TerraBuzzQ CPU Governor (Suspended)
I tried a few CPU governor which can suit my preferences that will turn off CPU core if the load is light to save battery.
And I come to LulzactiveQ by Tegrak that initially I think this is suitable for me. Nobody is using this governor for Note 2 and I dare myself to try it on my own.
Later on, I modified the source code for LulzactiveQ to remove some parts that I don't need and create my own logic for this cpu governor.
There are 3 thresholds for CPU load:
High Threshold = 100%
Up Threshold = 60%
Down Threshold = 30%
If CPU load = High Threshold (CPU Load = 100%)
CPU scaling per 200 MHz until it reaches maximum frequency 1600 MHz.
If Up Threshold < CPU Load <= High Threshold (CPU Load between 61% and 99%)
CPU scaling per 100 MHz until it reaches 1400 MHz and stop at that point.
If Down Threshold < CPU Load < Up Threshold (CPU Load between 31% and 60%)
CPU scaling per 100 MHz until it reaches 1200 MHz and stop at that point.
If CPU Load <= Down Threshold (CPU Load less than 30%)
CPU down to lowest frequency 200 MHz.
By this logic, TerraBuzzQ Governor suits my daily usage pattern and tested by beta tester team. The result is great battery life and no lag encounter in heavy game such as Real Racing 3.

*]Too much stuff to list here. See "Sources" below and check my Github
* HTC's Asynchronous Fsync and Dynamic Fsync:
Asynchronous fsync (called "afsync" or "async fsync") from HTC is ported into this kernel. By default it's enabled and dynamic fsync is disabled (and as well it isn't needed anymore).
The dynamic fsync toggle in Trickster Mod is now serving both functions - the dynamic fsync AND the asynchronous fsync! How? By default Dynamic Fsync is disabled, and Afsync is enabled. If you now enable Dynamic fsync using the toggle, Afsync will be automatically disabled, so both functions are not conflicting each other - and this way we have a working toggle for both of them.
CAUTION
This is a work in progress! Some of the current features are still not in final stat. If you are facing issues report back here and DON'T spam the threads of the rom you're using!
Be careful with some settings such like Voltage and Overclocking!!! If you aren't experienced with these things, dont play with 'em!

REQUIREMENTS
Rooted device
Must use a Kexec Rom (CM, AOKP, AOSP)
Recovery (BMM, SS)
REMOVE any kernel modules you used before
DEACTIVATE ANY CPU tweaks, onboot settings etc otherwise your phone may not boot!
CAUTION: The kernel needs a clean setup related to CPU tweaks / Settings, etc...Keep your device as clean as possible regarding to Tweaks, CPU special settings, etc. The Kernel brings its own CPU settings and after you can boot it succesfully, you can set it like you want!
Some roms may use CPU tweaks. This can cause issues like reboots and freezes. Check the init.d folder for any CPU related stuff and Kernel modules - then remove it. E.g. Remove any scripts which include "insmod" commands.
The best setting is to have stock CPU settings set
This kernel may not work on all roms! Check and report.
TO DO LIST
- Fix bugs
- Fix compile warnings
- More features.

2. Issues
1.1 How can I change the smartreflex minimum/maximum voltage
What is Smartreflex?
SR is compareable with an CPU governor but not for scaling frequencies but for voltages. That means SR has a fixed range of voltage (min/max) and calculates the optimal voltage for each CPU frequency. In example on light use of the CPU it scales down to lower voltage - on heavy use it can sclae to higher voltage. This is an efficient system to save power! Compared to EMIF which uses the hardcoded voltages it saves more power because it's variable. EMIF cannot vary between the values.
This interface has a hardcoded range of 830mV min to 1450mV max. Usually there is no need to adjust these values but irt can be usefull in example when using high overclocked frequencies above 1,5ghz! Usually SR cannot handle frequencies above 1,5ghz and I have hardcoded the maximum range of 1,45mV which should allow SR to handle it. In prior times the users had to turn off SR when OCing above 1,5ghz which causes the CPU to eat more power. But you can try around and report your results.
CAUTION: Don't raise the maximum SR voltage too high! It can burn your board = no phone anymore! I recommend to not use higher values than 1490mV! As already mentioned: THe default value should be enough!
ANd also: USUALLY THERE IS NO NEED TO CHANGE ANYTHING ON SR! IF YOU DON'T KNOW WHAT YOU'RE DOING, PLEASE LEAVE IT ALONE!
Ok, now let's see how to do this:
Turn ON/OFF SR
1. Open Trickster Mod
2. Head to the "Specific section"
3. Scroll down to "Smartreflex"
4. You can toggle ON/OFF SR for each component (IVA, CORE, MPU)
Usually I recommend to keep SR ON because it saves power! But in some cases when overclocking the CPU (MPU) the device could freeze - whether you OCed too much or SR couldn't handle the frequency! In this case you can try to raise the vmax value of SR a little bit (CAREFULLY!) and try again. If it sitll freezes and you're sure that you didn't OC too much, turn SR OFF at least for MPU!
Maximum Voltage
Currently there is no app which supports the feature of adjusting the SR vmax value, because I wrote this feature some days ago.
But in the next Trickster Mod version this option will be supported!
example:
# To read the current vmax value. Replace XXX with one of the following:
sc_core - for core max sr voltage
sr_iva - for iva max sr voltage
sr_mpu - for mpu max sr voltage (mpu is most related for CPU scaling)
cat /sys/kernel/debug/smartreflex/XXX/vmax
# You will get an output, e.g. for mpu = 1450000 (1450mV)
# To set a new value, do the following command (replace XXX with a value like above - BE CAREFUL! USUALLY THE DEFAULT VALUE ENOUGH AND YOU CAN LEAVE IT UNTOUCHED!)
echo XXX > /sys/kernel/debug/smartreflex/XXX/vmax
Minimum Voltage
It's easy because Trickster Mod supports it!
1. Open Trickster Mod
2. Head to the "Specific section"
3. Scroll down to "Smartreflex"
4. Below each SR component (IVA, CORE, MPU) there is displayed a value (usually 830 default) which means this is the lowest scalable voltage for this component. You can try to decrease this value for the case you want to UV a bit more - or raise it a bit for the case you think that the set range is too low and causes freezes on your device.
1.2 How do I use Live OC (Live OVerclock)?
This feature allows you to overclock the CPU in realtime. It works with a multiplier value set by the user. The default multplier value is "100", which means: No OC! If you want to raise the OC frerquency, just raise this value step by step.
FOr my device the maximum working OC value is "111" which means the maximum frequency is running at 1498mhz!
NOTE: Keep in mind that you tunr Smartreflex OFF for higher freqs than 1500mhz - or raise the maximum SR voltage range for "MPU" a little bit and test if it works.
Ok, how to use Live oC in action:
Open Trickster Mod App and swipe to the tab "Specific". There you will find something like this:
Code:
MPU OC [100]
DON'T TOUCH THE "CORE OC" SECTION, IT WILL CAUSE FREEZES!
Now slowly increase the value "100" to something higher, e.g. "105". Tap the hook in the right upper corner to confirm. To see your new set of frequencies you can now whether close and restart Trickster Mod or just use any monitoring app like Cool Tool which will show your frequencies in real time. That's it!
CAUTION: You can damage your phone forever!!!! This feature allows you to set very high frequencies (also up to 2,0ghz...) - That DOESN'T mean that your phone can run these frequencies!
If your phone freezes or crashes you have probably set too high OC - or your voltage is too low.
1.3 How do I use Custom Voltage (EMIF)?
NOTE: This only adjusts the fixed voltage! When you have Smartreflex ON it can still vary! You have to see the bigger picture: This voltage value sets the "middle point" for voltages. Smartreflex is still able to increase or decrease the voltage. When Smartreflex is OFF the CPU will stay on this voltage you set here and probably eats also more power.
How does EMIF works together with Smartreflex:
Code:
-------
| CPU |
-------
|
------------------ ------------------
|Voltage 1015 mV | ---->| SMARTREFLEX ON| = 1015mV +/- "vmax"/"vmin"
------------------ -------------------
|
--------------------
|SMARTREFLEX OFF| ----> 1015mV FIXED! No changes!
-------------------
Thi smeans if you change the voltage for a scaling step (OPP) while SR is ON, SR will adjust the voltage from this value, means: mV-Value +/- SR vmin/vmax. WHen SR is OFF it will stay on this mV as a fixed value.
How to adjust the voltage?
Well, this feature can be used with all generic apps which are supporting voltage settings. But we are prepared well, you can adjust voltages also with the "Trickster Mod App".
When you open the app, head to the tab "Specific" and below the "Live OC Section" you will find your voltage table, which looks like this:
Code:
<-->
1200 [1398]
1000 [1388]
900 [1371]
...
..
..
Now just tap the arrows in the right upper above the first voltage value and just type or tap (per direction) a value, e.g. "-25". To apply it, confirm by tapping the hook in the right upper corner of your screen. That's it, your new voltage values are now set and applied. And also mind here: If your phone freezes you porbably have set it too low.
CAUTION: NEVER SET HIGHER VOLTAGE THAN 1490mv here!!!!! Or you might damage your phone FOREVER!
This voltage is not the same like Smartreflex! But it's still voltage! Just be carefull!!
1.4 How can I use GPU OC and GPU Governor?
GPU Overclock doesn't work like Live OC! You cannot really set custom frequencies for the GPU, but you can select and set the maximum frequency from a hardcoded range!
For the GPU there are the following available frequencies:
154mhz (FIXED!)
307mhz
384mhz
416mhz
The minimum frequency of 154 is FIXED! This means you cannot change it because the GPU needs a minimum speed to run with. But the kernel allows you to select the maximum speed. This can be usefull for playing games and also for saving power . In example when not playing games you don't need the GPU to run at 416mhz! Set it to 307mhz in this case and save power.
When you open Trcikster Mod and head to the "specific section tab", you will find "GPU MAX FREQUENCY" and it's currently set maximum frequency. Tap on it to select your preferred one:
- 154 Mhz
- 307 MHz
- 384 MHz
That's it. The new setting will be your new maximum GPU frequency.
Below there's another option called "GPU Governor". Just tap on it and select your prefered one.
NOTE: If you want to track current GPU frequencies and watch governor's behavior, just switch to Trickster's "Informations" - Tab and watch the frequencies clock.
1.5 How can I use Gamma Control?
What is gamma? The gamma setting sets the color range for the screen. You can compare it to the contrast. We all know that the touchscreen eats most of the power compaerd to all other components in a smartphone! A lower brightness causes less power consumption and a lower gamma or contrast range alos helps a little bit to save power.
In this kernel you can choose from a range of "5 - 10" while "5" is very bright while "10" is very dark. The default setting is "5" BUT CAUTION: Trickster Mod will display a range of "0" to "10" and the default setting will be shown as "0". This is caused by the fact that this feature was ported from the Gnex device where you can choose from a higher range. The only sideeffect is that the values "0" - "5" won't show any difference.
How to set the gamma value?
Well, once again open Trickster Mod and swipe to the tab on the right end. Just select your preferred value by using the slider.
Alternately you can use sysfs by terminal or adb:
OMAP Gamma interface:
echo i > /sys/devices/platform/omapdss/manager0/gamma
Replace i with 0-10 of your choice.
1.6 What is "Battery Friend and how to use it?
Battery Friend is a simple toggle (ON/OFF) which sets your device into a battery friendly mode without the need to play with all settings in Trickster Mod /sysfs until you find a good setting. In fact it does the job for you.
What does it affect?
NOTE: Doesn't lock anyx frequencies anymore!
locks dynamic Fsync enabled
locks Fsync disabled
Doesn't allow any OC (Live OC will not have any effect, Core OC is not allowed in this kernel)
Increases the dirty ratio interval to 90% (starts working at this value)
Enables Dynamic Hotplug: This doesn't allow hotplugging during device is active - and it will always turn CPU1 OFF during suspend! It also prevents from conflicts when user uses a hotplug governor (which isn't a good idea though) - but hotplug governors are causing higher battery drain!
Dynamic Page-writeback always enabled
How to toggle Battery Friend:
For now the only way is via terminal, adb shell or root explorer (text editor)
For terminal and adb:
Code:
echo 1 > sys/kernel/battery_friend/battery_friend_active /* Enable */
echo 0 > sys/kernel/battery_friend/battery_friend_active /* Disable */
For Root Explorer
Open Root Explorer
Navigate to sys/kernel/battery_friend/
Open "battery_friend_active" with Text Editor
Change "0" to "1" and safe the file to enable
Change "1" to "0" and safe the file to disable
1.7 Suspend Governor Control (CURRENTLY DISABLED)
Suspend Governor Control is a kernel module written by me. You can use it to set your preferred Screen-Off-governor.
For now it's only supported by sysfs (Trickster Mod will support all my current and upcoming features as soon as it gets updated with its new UI mode!
How to set suspend governor
Open a terminal or use adb shell
Code:
su
echo "x" > /sys/kernel/suspend_gov/suspend_gov
Replace x with one of these values:
0 = Ondemand
1 = Ktoonservative
2 = Conservative
3 = OndemandX
NOTE: No matter what governor you use for suspend mode, if Battery Friend is enabled the second core will be turned off during suspend!
1.8 IVA Overclock
What is IVA OC?
IVA OPPs are controlling the CPU load for sound events. It could be useful (in some cases) when you get sound related laggs. Just set the maximum frequency to highspeed. This will allow more CPU power for sound events but also will cause higher battery consumption.
How to use IVA OC?
If you want to check the current IVA frequency. Just type in Terminal or ADB:
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/iva_clock
You will get an output like this:
Code:
132 Mhz
2. You can whether enable IVA highspeed: 130 - 430 Mhz ["1"] or enable IVA normal speed: 130 - 332 Mhz ["0"]
320 Mhz max: echo "0" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc
430 Mhz max: echo "1" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc
1.9 DPLL Cascading
DPLL: Davis–Putnam–Logemann–Loveland (DPLL) algorithm
To get more info about this please see wiki
But to sum it up shortly: It helps to use/stream media (music) in a low power mode.
NOTE: DPLL Cascading will be available to be switched easily via Trickster Mod App soon!
How to switch DPLL?
DPLL is ENABLED by default!
Open Trickster Mod -> Speicific Tab --> DPLL (soon)
sysfs:
Turn off:
Code:
echo 0 > /sys/kernel/dpll/dpll_active
Turn on:
Code:
echo 1 > /sys/kernel/dpll/dpll_active
1.10 HDMI toggle
Some users are facing a RAZR-sepcific problem: HDMI cable is detected, even though there is no cable plugged!
Therefor I included a toggle to switch HDMI wether ON or OFF. Additinally there's an init.d script included within the AROMA Installer you can select during the installation of JBX-Kernel.
To enable/disable HDMI on-the-fy:
sysfs:
Turn off:
Code:
echo 0 > /sys/kernel/hdmi/hdmi_active
Turn on:
Code:
echo 1 > /sys/kernel/hdmi/hdmi_active
1.11 Intelli-Plug
For intelli-plug hotplugging is now only allowed when the device enters sleep.
To enable hotplugging universally just change the value of the following entry whether to 1 (on) or 0 (off):
Code:
sys/module/intelli-plug/parameters/int_hotplug
*Unfortunately I don't have enough space in the OP to write all this into the FAQ, that's why the I only added the sysfs path, but the description is simply here
2. If anyone has the following issues:
Issue
Media Process FC
No SD-Card in File Explorer
My CPU Settings (frequencies, etc) won't be saved (it sets itself back to Kernel default after screen off)
My phone freezes/reboots always when I try to set options in Trickster Mod
The device is lagging very hard
Solution
Media FC: Open App settings, head to "Download Manager" and "Media Storage" and hit the "delete data" button. Reboot. Now it shouldn't give any FCs anymore and after a little bit of waiting it will find all Media (Pictures, Videos, etc..)
No SD-Card: Reboot into recovery, go to "Mounts & Storage", tick "mount int" or "mount ext".
USB: Make sure the screen is ON while plugging the cable in.
CPU Settings: This is a bug which cannot be solved at the moment. Temporary solution: In Trickster Mod just activate the "Frequency Lock" and your settings will persist.
Trickster Mod:: Open App settings, Trickster Mod and select "uninstal updates". Now it should work.
Crashes, Freezes, lagging, something doesn't work, etc
There are too many reasons which could cause crashes! So here is a checklist for you to look for. Check each point and try the following workaround:
- Your rom has CPU tweaks (e.g. Kernel modules, init.d folder, etc)
- You have set custom CPU settings (e.g. custom frequencies with apps like No-Frills CPU Control, Set-CPU, Antutu, etc...)
- You have undervolted too low
- You have overclocked too high
- You have applied higher "Core OC" value in Trickster Mod App
- You are running any other kernel tweaks which are regarding to the CPU and/or performance (e.g. Kernel modules by Whirleyes eventually set by init.d, etc..)
- After setting some settings (e.g. in Trickster Mod) your device doesn't boot anymore
- adb doesn't work / shows only "device offline"
- You are facing hard lagging
If any point here matches your setting, please revert from it:
- Remove any CPU init.d script from /System/etc/init.d
- Uninstall any CPU controling app (e.g. Set-CPU, No-Frills, etc..)
- Remove all extra kernel modules from system/lib/modules (e.g. cpu_control.ko, cpufreq_smartass2.ko, etc..)
- Unset any custom settings from any other kernel / CPU - tweaking app which is NOT Trickster Mod
- Maybe your governor causes issues. Hotplug is know for bugs at the moment...I'm going to fix it..
- NEVER set your CPU Settings (e.g. in Trickster Mod App) on boot!!!! - before you aren't sure that your settings are safe!!!
- You may flash the kernel again after reverting related settings
- to make adb work / show device online, download latest SDK platform-tools and confirm access on device (4.2 security feature of Android)
- Don't use any task killers, memory killers, seeder apps! They may conflict with the kernel/Rom settings.
If none of these suggestions work for you your rom may be incompatible. Please report it here that I can add the rom to the list of imcompatible roms
If you have any issue, please read this:
First check:
- is it really a kernel issue?
- did I see this bug with the roms original kernel?
- what are the people in the rom thread saying?
- what are the people in the kernel thread saying?
- can I find this issue on a bug list?
- how about my settings? Is it my fault it crashed?
- can I find something useful in the kernel FAQ?
- Is it maybe a well known issue and can be solved
withing seconds? Just like wifical.sh?
- Where to repeat that issue? Rom or kernel?
I know it's sometimes difficult to track the issues, and we can't know for sure if it's caused by the rom or by the kernel, but if you try at least to get some information you might find an answer sometimes. If you are able to understand logs, you may report whatever you find.
All this helps to keep the threads more clear. Thank you.

I need the internal storage mount points from someone with stock kernel, please. I saw something about mmcblk0 - int ? Please anyone check the /mnt partitions and tell where the internal and external sdcards are mounted. thx
Edit: nevermind, I didn't know this device doesn't include an internal storage. Now I need to know if USB mount works on Devesh's Rom ports.
Used Stock ICS Based ROM on System 1 with BMM , and Mobile Terminal .
hope its ok .
Wow !
I see some awesomeness coming to our A2s *Respect*
All is set up. Everything works, so I will now build the first test kernel for you guys.

So with the current version there is a bug with OC ? ( i don't see TEST2 for Atrix like with the Razr version).
Yes, device starts lagging when OC too high (over oc value of ~107). But new release comes with fixes - OC up to 1,5ghz possible without any problems (Mine crashes when OC higher than 1,498mhz, each silicon is different).
I think I will push it as a release (not NIGHLTY) - only thing left to be fixed is the random black screen while booting. But that's not that important as long as the kernel works well when booted successful.
Edit. done!
Great can't wait to boot 1498mz!

Can I get a wohooo for the A2
I just need thermal config+init.qcom.post_boot-1.sh with some modification...
My requirements are as follows...
1) dont care about heating.
2) cpu governor- interactive
3) min clock frequency- 100 mhz for all cpu
4) maximum clock frequency- no limit
5) camera app not depends on temperature ( hang or slow at high temperature).
6) remove all cpu throttling...(must need)
7) remove cpu offline algorithm... (Must need)
Anyone here which is capable of doing this thing,please help...
my thermal config has it all. have you check ?
only the cpu freq I don't set as low as 200 in interactive. (the minimum) you'll get lag and slow respon. believe me.
but I can change if you want.

thanks...
Thanks dude for your advice but i tested your procedures,after that still some cores shut down according to temperature...
i know your skill,so lets join my algorithm and your skill to make best config files...
1) dont care about heating.
2) cpu governor- interactive
3) min clock frequency- 200 mhz for all cpu
4) maximum clock frequency- no limit
5) camera app not depends on temperature ( hang or slow at high temperature).
6) remove all cpu throttling...(must need)
7) remove cpu offline algorithm... (Must need)
and dont confuse between hotplug and throttling(hotplugging is turn unused CPU cores off during periods of low CPU utilization and throttling is turn CPU cores off according to temperature)...
also if you can do then set first 4 core(1.65 mhz x 4) at interactive and others (1.1 mhz x 4) at ondemand...
believe me...this makes best algorithm to control heating and increase performane

Click to expand...
Click to collapse
if you're talking about cpu2 & cpu3 still offline then I can't help.. it's because of the kernel.
they are active as per need though , not totally offline.
thermal config should be good for your need (if you want can remove all the SS-CPU in there )

post_boot.sh later.. ( i think Keasby has one with mix interactive/ondemand)
Explain
thanks for your hard work but can you tell me changelog of this config files according to my requirement...
Thanx but there is a problem
Yes you here right,i just checked your config file,i think this is perfect mod but it does not support miui 6.7.2... After some time frequency of first four core set to 1651 mhz and rest at 800 mhz...please fix this issue,it makes heating issue...
