[Galaxy Tab 4 General] 7gill:
Hey everyone! My name is Kori. So i have been homeless for awhile.Been usinf 2 lg motions as my enertainment.Watching video and typing was annoying on such small screens.

About new years i got a few extra bucks and ended up buying a Samsung Galaxy tab 4 7".

This thing was possessed with Demon Scripts. 2 minutes after my first boot i get notifications the phone cant see my eyes. Every time i touched the phone or even thought about it Power Manager,SSRM and DVFS get twitchy and bump my cpu_minfreq to max.

Chargin my battery isnt always possible when your "Camping" So i began Un-Development.

Then noticing Low Volume ,Weird Wifi and several other problems

My wifi would drop or data transfer would drop. I found that when connected with low signal icould run file in /system/bin called oem_iptables_init.sh would g3t me a data flow again. Then i noticed there seemed to be 2 sets of wifi and bluetooth drivers.

Anyways heres the bulk.

I have removed almost ALL the junk i dont need.

Selinux disabled. Knox is disabled

telephony is all gone. All but the jar and odex in frame"though i removed all permissions to the odex.

Nvm is gone and doesnt load. That means all rf reductionstables as well.

Csc is gone

nothing loads from /NVM , /etc/tel or /system/csc

removed Enterprise SSRM Dvfs has been cut out. Turned off all motion .palm swipe,air motion,smart stay and whatever else

Also managed to Stop several services that are useless to me

So nothing THERE IS NOTHING IN CONTROL OF MY CPUS EXCEPT FOR MY INIT.D SCRIPTS.AHhhhh

i have None of the original apps such as

touchwiz home,keyboard.camera,gallery,Lets say everything¡

All thats left from stock is like google play 'and its apps',settings,mtp,vpn,kies,bluetooth,cert installerand a few others

I mean completley stripped

i have a ton of apps on my phone including 5 or 6 social apps and 2 messenger apps. After a bootup phone idles on one cpu core on st 312 with about 700 to 650 mb of free ram

yes,i unlocked the Hotplug feature.And drastically changed the load balancing to the cores.

This allows the phone to Turn On and Off cpu cores as it needs. Saving battery life with great performance.

I have managed to Increase Volume also.Woooooo

Battery is way better now ,much better wifi. Tons of room in system for my apps. I control my phone now not Google Samsung Selinux Knox Enterprise NVM SSRM DVFS MPDCand all the others.

I have cool init.d setup i made with basically 7 init.d setups or profiles to choose from to exe at boot as well as 6 profiles you can run in realtime. Also 2 sysctl profiles to choose to boit from or exe in realtime.

Also i have tons of init.d settings for this tab i like.

Gettin tired of typing So i will be back with several How tos for you.

but here is something to play with

unlock hotplug

/sys/devices/system/cpu/hotplug/lock change to zero

This the current setup i have Though i think i need a few adjustments in load balancing

But it nice. Lets cpu idle and perform o cpu0 only but keeps a second core close to Help

Keeping the other 2 cores off until really needed

echo "0" > /sys/devices/system/cpu/hotplug/lock

echo "312000" > /sys/devices/system/cpu/hotplug/bound_freq

echo "10" > /sys/devices/system/cpu/hotplug/load_h0

echo "40" > /sys/devices/system/cpu/hotplug/load_h1

echo "70" > /sys/devices/system/cpu/hotplug/load_h2

echo "16" > /sys/devices/system/cpu/hotplug/load_l1

echo "35" > /sys/devices/system/cpu/hotplug/load_l2

echo "50" > /sys/devices/system/cpu/hotplug/load_l3

using this as Governor settings

chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

#chmod 777 /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

#echo "990000" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

chmod 777 /sys/devices/system/cpu/cpufreq/ondemand/up_threshold

echo "85" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold

chmod 777 /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

echo "1" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

Aslo keeping the cores limited to 1066 mhz max.

chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

echo "1066000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Alright going 10-7

Over
