UPDATE 8/24! Please go to the site and download the latest version RC1b which corrects 2 small bugs people have reported. It now sets the proper permissions on batt-diag so it runs, and it changes the way the program tries to SU so that you can choose to not have the program attempt to run SU if your rom has trouble running su from terminal;
---Original Below---
I decided to create a new forum for the latest battery tweak as so much has changed since the initial versions.
To get things started, I'll just say that collin_ph battery tweak is a collection of scripts designed to make the hero (for now) last longer on battery, run faster, and run better. The tweak includes CPU management, Battery Management, Disk Performance Boost, Scheduler Boost, LED Fix, Audio Quality boost and other features to improve the usability of your Hero.
Instructions: Go to http://www.primoweb.com/froyo to download the latest version and get the documentation.
Boot into recovery and flash the zip file.
After reboot, you may run batt-cfg from shell or terminal (Note, that the scripts will all request root access, so there's no longer a need to su before running them).
to run batt-cfg
go to terminal in the phone or use adb shell from your PC
once there, type
batt-cfg
It will pull up a menu of choices. For further info, see http://www.primoweb.com/froyo
You can load a 691 mhz default (most Cyanogen kernels now only support up to 691 mhz anyway), or, if you have an uncapped kernel, you can choose a 768 mhz setting. Note: Both settings actually run at 691 when on battery and only run higher when plugged in.
The basics of how the battery is extended is that this tweak causes your phone to scale down (to lower frequencies) faster and to scale up slower. In stock configuration, the cpu scales up when only under 70% load -- while part of this tweak causes it not to scale until it's at 95% load, avoiding unnecessary scaling and battery drain. A second (and arguably more important) feature, is that as the battery drains, it lowers the maxumum CPU frequency. So when you have 1% battery left, you may be running at 468mhz instead of 691. Another plus is that the phone runs in a "higher performance" mode while charging via AC, and another mode to make sure the phone is actually charging when connected bia USB, in addition to the settings mentioned above when the phone is on battery.The best part is that almost every parameter in the system is adjustable through terminal or adb shell using a program called batt-cfg -- just run it and you'll be presented with a menu of options.
I'm constantly updating the documentation, so please check back often as I'll update this thread until there's a final 3.0 version. We're already working on a 4.0 which will be available on the market. We'll post more info there as it happens at www.tweaktool.com
COMPATIBILITY NOTES:
This tweak only works with clockable kernels. A lot of ROMS have reclockable or overclockable kernels which should work. I recommend Froyo roms, but I have heard of the tweak running with 2.1 releases. The main incompatibility seems to be with the service startup-- on some roms, the service doesn't automatically start up.
to verify if your rom is compatible and that the tweak is working, reboot.
Then go to terminal or adb shell and type:
pidof batt.sh
if it returns a number, then the service is running. If not, you'll have to start it manually every time the phone reboots by going to terminal or adb shell and typing
batt-cfg
then choose the option to save and exit. This will manually start or restart the service. Note: if your rom does not start the service automatically, you'll have to do the above batt-cfg procedure after EVERY boot or battery tweak will not run.
If you're a ROM developer, you'll can probably make your ROM compatible by adjusting your rom (ramdisk) to call (import) /system/etc/init.local.rc from init.rc -- assuming your ROM has an overclockable kernel like fresh, darch, or others.
ROMS based on unclockable kernels like Damage Control, won't work without a kernel upgrade and may still not start the service automatically upon reboot.
Thanks to Decad3nce for testing and improving several parts of the battery tweak.
So to flash this tweak and have it working on the latest Froyo nightly, do we need to flash overclockfix.zip ??
I had to flash this fix almost with ever nightly, coz the frequency list would not show up when i need to customize tweak settings.
I was reading the documentation and saw the CFS tweaks are disabled by default. Will this correct the GPS issue that was on beta 10?
Froyo Hero to the rescue
Thank you for all your work on this, got 12 hrs on 50% today with beta 10 and Decad3nse #8, 768 pre-set, most time I've ever gotten outa my Hero. Flashed your RC1 (with Darch's RC1) about 45mn ago and used custom settings to jack-up the max to 768 across the board, min.s and intervals stock. Thank you for explaining the 768 pre-set is really 691! Gonna sit on what I've got for a day and then try w/ Darch's "fix" kernel. Hope I can keep the max on batt @ 768 'cause it seems to make my Hero more responsive/less laggy.
I was not able to use the batt-diag in adb shell. I'll report back tomorrow how the tests go.
What is the procedure for installing this if you're currently running Beta 10? Do you have to wipe, reflash, etc or can you just flash the update and reconfigure in adb?
it made my hero laggy!!!

Excellent tweak! Used it through Beta and now enjoying the RC. Well done!
wow.. the way things are going i don't think i am going to jump into a evo... i am loving my hero so much.... thank you for all your hard work..
OK I don't know if its just me but when I go into batt-cfg it just runs whoami uid o
Batt-cfg root
Or something like that over and over again. It worked on beta 10 but not like this I don't understand
8/22 RC1 update does not have a working batt-diag, says not found. I am getting "89" when I do "pidof batt.sh"

hmm.. what rom are you running? It sounds like the code I've got in to detect root (and ask for it if necessary) is causing an issue with what you're running. All it does is a whoami to see if you are logged in as root, if not, it su's and relaunches itself.
I'm getting the same root problem with 8/22 nightly.

I'm using my red dawn rom with a modded ramdisk to allow for the battery tweak. The beta 10 worked and even the rc1 asked for su and I said allow the the whoami just kept going and going. I uninstalled via ur instructions on ur site and flashed again and same results
RC1 kept crashing my phone. Right after saving settings it would freeze them hard reset and get stuck at the htc screen. I've reverted back to beta 10. The only problem I've ever had with beta 10 is I would have random hard resets when charging. I really can't even pin point it on this tweak but its the only thing that I could think that would do it.

Were you doing the updates through ADB or terminal? When would it hard lock up.. during save changes?
CFS Tweaks and Decad3nce Kernel
I understand from reading the Kernel info, that the CFS on this tweak needs to be disabled first....did you make CFS tweaks on by default? Arent we supposed to flash the kernel first, then disable cfs tweaks and reboot? Im confused as to the order in which things are flashed. WIPE, ROM, GSHITZ, BLACKMOD, KERNEL#7, COLLINS RC1. Then go to term EMU and disable CFS, then save then go back into batt-cfg and choose option 1 768 and save and exit then reboot. Woudl that be correct?

Introducing my first build for a kernel+ROM combo with battery profiling which decreases the speed of the CPU depending on battery level. It is automatic and overclocked at 1504 ghz and goes all the way down to 912 mhz. More details of the kernel and ROM below.
---------
KERNEL
---------
1. Includes Blades overclocking features with max at 1646 mhz (very stable in my tablet)
2. Includes undervolting feature (thanks to CPAjustes)
3. Includes voodoo sound (thanks to supercurio)
4. Overclocked 2d/3d gpu at 400 mhz
5. VDE and sound overclocked at 300 mhz
6. Based from ASus release
7. data/app feature included
8. netarchy's disable tap included (just download his app to enable)
9. VOLTAGES per frequency are as follows
1646 - 1450mv
1600 - 1400mv
1504 - 1300mv
1400 - 1200mv
1200 - 1150mv
1000 - 1100mv
912 - 1050mv
817 - 1025mv
760 - 975mv
608 - 950mv
503 - 875mv
456 - 825mv
314 - 800mv
216 - 750mv (can be uundervolted to 725mv per Pimpmycpu)
------
ROM
------
1 Battery profiling (Thanks to Calkulin) are as follows
a. automatically overclocked at 1504 with battery level at 100-90%
b. overclocked at 1400mhz when battery level drops to 90-50%
c. overclocked at 1200mhz when battery is at 50-15%
d. underclocked at 912mhz when battery level is at 15% and below
2. Battery profiling is automatically disabled when SetCPU is installed so you can overclocked more when you install SetCPU (or you can edit the init.d script)
3. Pimpmycpu is installed for undervolting and stress testing
4. Voodoosound App free version is installed
5. Dual battery widget installed
6. RAM script optimizations include (Thanks to Juwel)
7. CPU governor set at interactive
8. SDCARD optimization script by me and Calkulin
9. Based from 8.4.4.7 release
10. system/app deodexed (thanks to Roach2010 for this)
Here is the link
www.tunerspotter.com/clemsyn/CLEMSYNkernelROMcombo.zip
HOW TO INSTALL:
1. BACKUP..BACKUP..Backup
2. Enter Clockworkmod Recovery
3. Clear data/factory
4. Install zip file
5. Reboot
TIPS
1. Please do not enable "Force minimal freq when sleeping" in Pimpmycpu because it will have a conflict with the battery profiling script.
2. Install netarchy's app to disable tap to click
3. Install Setcpu to disable Battery profiling script (will allow you to overclock more)
4. If you want to overclock (or underclock) more without installing SETCPU, edit the init.d script at /system/etc/init.d/02cpufreq_screenstate_scaling
5. To try a certain speed without installing SETCPU or editing the script. Enable the frequency at PIMPmycpu and you can test it out. It will default back to battery profiling speed when the screen turn off or when you press the power button.
BTW, this is an overclocked build so your mileage will vary If you are unable to boot at 1504, do not install this. Thanks.

Sweeet !! Do we know how much battery saving that can give ? Is is a drastic change ?
Good work !
Testing it right now.
I spy with my little eye, a new ROM for me to try!
LINK is up. BIG thanks to chatch15117 for the ftp site

Would really depend on how much you can undervolt your cpu (via pimpmycpu) and how you set the profiling frequencies at (editing the init.d script). With the script, you can edit a certain frequency at a certain battery level Ihave included File expert (to mount system/etc as rw) and Estro File explorer
This looks awesome! I'm excited to use this combo, will a restore of stock rom data cause issues? I figure it does hence the backup/wipe steps but its still worth asking
Sent from my pimped out cappy
yup,that is what i`m talking about more roms more pleasure for us
awesome job Clemsyn
Wow, nice work.
But i'm only interessted in the kernel. Will you further support the other thread with your kernels?
4. If you want to overclock (or underclock) more without installing SETCPU, edit the init.d script at /system/etc/init.d/02cpufreq_screenstate_scaling
What if I want to overclock the gpu some more? Can I do that?
Thanks Clem!!
Great to see new cooks in the kitchen, variety is the spice!
I am keen to try your ROM combo without installing SetCPU, however wanted to ask a question.
AS we all know, when we sign into market our tablets efficiently start automatic download and installation of programs we have purchased/previously installed.
I purchased SetCPU a while back and it's often one of the first apps to get installed.
I will try to be quick and cancel the installation, but wondered if it does happen to get installed, and then I uninstall it, will the automatic CPU throttling settings be messed up or will they automatically kick back in if they see SetCPU is uninstalled?
Thanks!
One other really important question:
Does this have the option to boot into recovery (long press power) like Prime 1.5?
Just makes any future changes that much easier.
Thanks.

If setcpu is installed, then battery profiling script is disabled. If uninstalled, then battery profiling is enabled upon reboot.

When setting up your gmail account after flashing a ROM you don't have to load previously installed/downloaded apps. Just don't check the "Restore data from my account" tick box.. Might be named slightly different but that's the gist of it.
If you have it load to reinstall your apps then you can get around this by either using Titanium Backup, or Astro file manager has a free app-backup but it doesn't work as well (can't get secured apps, etc.)
browser fc
Everytime i go into browser settings i get fc.... tried clearing data in apps... no dice.
Smooth rom otherwise ! Looking forward to updates.

Try using Pimpmycpu and choosing a lower frequency for max (don't turn off the screen or else the battery profile will push it backup to 1504).
Can it be use with CPU Master instead of setcpu?
If not, what is the different with working with one but not the other?
As the title says:
Does Overclock pay?
I especially mean, is it really remarkable on games (angry birds seasons eg), transitions, general performance?
Which method/apk u use(d)?
How much do you personal overclock?
Is it stable if phone´s use long times?
concerning this, what is a governour?
Thanks in advance for your answers

Well to be brief it pays
Though the entire experience is not that good if you try to run an HDPI game on our LDPI device, you can experience some lag of half screens
but other games like angry birds and all run flawlessly
The FPS of the games increase by appreciable numbers(Like sandstorm and other gameloft games ), though I havent yet faced any stability issue (Except the frequent Market FC) other things work normally
I use Lagfree governor and Deadline I/o scheduler
In short words governor determines how the frequency of the cpu changes with respect to the load on it
Thank you for the reply.
So I know it pays to overclock, now, as I won´t brick my second fit, is a question to me, how do I do this in a secure way?
Is is depending which ROM I use?
Is it APP or do I have to flash Kernel?
If it is Kernel which one matches with my ROM?
Many Questions, but before I make this step, I´ll be as sure as possible about this topic.
i've OCed my galaxy fit and so far i'm getting the best of my phone without any drawback. well if there IS a drawback, i think the only drawback it has is because of the governor which causes the phone unstable.
and to answer what a governor is, it's simply like a CPU manager which controls ur CPU speed at anytime. suppose i put my phone in my pocket and i don't use it, of course i don't want my phone to work 100%, no? so the governor slows down the CPU speed. of course, u can control what is the minimum speed of ur CPU (so far it's as low as 122 MHz for galaxy fit) and also what is the maximum speed (so far it's as high as 801 MHz)
there's so many governors but so far, the most battery conserving, yet doesn't sacrifice your phone performance when u need it most, is interactiveX. and the most performance efficient, yet doesn't suck a lot of battery juice when u don't use ur phone, is smartassV2. if u wanna know more about governors and I/O schedulers u can check it here
so far, the only OC-able ROM i know for galaxy fit is CM7, which is still unofficial but working properly without any significant bugs. and yes it needs to be flashed using CWM (it's CWM v5.0 for galfit so far). after u do that, u need to install some app like "no frills CPU" (market available) or "setCPU" (also market available) to make use the governors and set the max or min speed for your CPU.
to sum it up, how to OC ur galaxy fit (if u're using stock ROM or by now, CREED's ROM):
1. install CWM (ClockworkMod Recovery) link for tutorials and reference
2. flash CM7 (CyanogenMod 7 custom ROM) using CWM. link for tutorials and reference
3. flash ur kernels using CWM also. link for tutorials and reference
4. install CPU manager app like no frills or setCPU.
5. set ur max/min CPU speed, and choose the governor properly.
*update*
sorry for the wrong link. and by the way, did u bricked ur previous galaxy fit by using ROM manager? if u did, be careful coz this CM7 is pre-installed with ROM manager. i suggest u uninstall it immediately after u've flashed ur CM7. install Titanium Backup then go to the backup/restore tab, search the ROM manager, then uninstall it. ROM manager still isn't compatible with galfit tho
that's it and i don't mind u clicking the thanks button
Thank you also for the comprehensive answer.
I just have another question to that (gosh I hope I don´t get annoying to you all folks):
As I am using CWM and running ext4 and did the backup of my actual sys and would flash to cm7 like described in your answer, the cm7 is working fine etc, will I be able to "switch" back to Creeds ROM by chosing my backup, using cwm or do I have to flash it all anew?
i'm afraid i don't know the answer to that, sir.
well say that u've done the backup now when u're in CREED's ROM, u flash it to CM7 then u wanna revert it back to CREED's ROM, i think the safest way is to flash it all new the CREED's ROM, then do the restore data using CWM.
well, my guts say that if u're in CM7 n u do the restore data in CWM, u'll get back your ol' CREED's ROM, but it's just my guts sayin
I´ll try and report
I tried to start, but your links lead all to the same, the cwm Install Instructions.
still need cm7 link (cuz I am not sure which one of that) for cwm and the oc kernel (which I also dunno, which one of them. So if you pleasssse ...

okay, i've updated my post. it now should link you to the proper post. don't forget to check my note on that post too though.
thanks for correcting and also the notes.
Yeah I bricked it by using ROM Manager, but it was completely my fault.
I wanted to fast, without reading AND a special portion of being silly
If ya like read this:
http://forum.xda-developers.com/showthread.php?t=1367853
I do it with cwa this time backup is already made
edit: dunno what is meant by mount /system? What do I have to expect, when I am chosing this and what does it do?
As far as I understood is it being made between cm7 and oc-kernel installation. Right?

mount system is a command to mount ur system folder in order to install the required. in this case, u're installing the kernel, so u need to mount the system in the recovery mode. to do that, go to recovery mode (since now u're using CM7 u can go to rec mode using the power button, choose reboot, choose recovery). then choose mount and storage, choose mount/system. don't worry, it's completely safe.
by the way, u also need to mount system for installing google apps in ur CM7 ROM. CM7 ROM is not preinstalled with google apps (including market, maps, and so on), so u need to install it manually using CWM also, flash the zip files provided in the tutorial thread. it's called gapps_bla bla bla if i remember correctly.
when i was flashing the google apps, i didn't get the market and maps application. so i install it manually using this link.
but i just read some guy with the same problem, n he said this.
haven't tried the later, maybe that'll work also.

Thanx again for all the effort. Sleep is an overestimated thing
But to be serious. I also slept and thought about that all and decided, first to stay with Creeds Rom, cuz it is fast, runs stable, looks good and has many features I apreciate.
Maybe I come back later to that point I wanna Install cm7oc, then I know where to look.
Still lets me no rest.
There´s still a new question in my head about the OC-Kernel.
there are many to chose, so which one is the most stable?
------------------------------ Smart boot 17 feature Governor, SIO, VR, BFQ, CFQ, Deadline, noop --------------------
Download Link for OverClock kernel (763Mhz ) smart boot 17 feature Governors

use CWM, and before flashing , dont forget to mount /system first and then flash this zip file
use no-Frills for OC and I/O setting
if get unstable , please set max 600 Mhz again, enjoy
DO IT WITH YOUR OWN RISK !!!!

There are two 768 MHz and 801.2 MHz
Both are stable
There is also a general question about oc.
why can´t I just use an overclocktool like no-frills or cpumaster on any kernel?
They "promise" to increase speed, so why install OC Kernel first?
Although I know it must have a reason, cuz you oc-guys all do it.
kernel is the cars engine
no=frills is the accelerator
thats the way i understand it /
yes overclocking your device gives you that extra mile ..by which you can run apps faster ..your phones bagginess goes!!! but has its cons also!! ..it does reduce your life expectancy of cpu atleast theoretically .. and you will get reduced battery life + your device will heat up a bit more than usual! ..other than that its awesome to have an oc.
I finally can conclude, Overclocking really pays. And still I can decide to keep my OCed cell running with 600 at max or give it a little or maybe big OC.
Thank you all guys for helping me, sharing your knowledge.
I am searching for a program like no-frills, which can also decide by profile (maybe even autodetect) when my phones connected to charger ---> use this profile/governor, if it is running from battery ---> that profile.
Does a program like this exist?

USE THIS AT YOUR OWN RISK.
I am not installing this kernel on your device. I've even gone out of my way to not give clear directions on how to install it yourself. If you decide to install this kernel, you are assuming all risks involved with it.
WARNING: THIS KERNEL IS NOT FULLY COMPATIBLE WITH THE LA3 FIRMWARE UPDATE. USING THIS KERNEL WITH THE UPDATED VERSION WILL RESULT IN WIRELESS ETHERNET BEING DISABLED.
Welcome to my custom compiled kernel for the Samsung Galaxy Tab 7.0 (wifi only.) This kernel will ONLY work for the GT-P6210 model.
The kernel should be compatible with any stock firmware or anything custom that's derived from the stock firmware. (I refuse to call it a ROM. It's not Read Only.)
First, proper credit should go to Entropy512 and his SGH-i777 kernels. It's from that work I was inspired to do this, and from that work where I'm pulling ideas and changes (when compatible.) I'd give some credit to Samsung, but they only bothered to post partial source code, and didn't even bother to post it with the proper config flags.
The idea behind this kernel is and will be to make the device more efficient. Longer battery life while running more smoothly is a Good Thing. I don't care about benchmark scores. In case someone missed that, I DO NOT CARE ABOUT BENCHMARK SCORES. Anyone can tweak a system to get a better benchmark, but that doesn't mean it'll actually work better. Concern #1 is and should always be stability. While some tweaks will be added that allow a user to make the system unstable, they won't be the default.
Differences from stock currently include:
Very slight speed increase in bootup, possibly in other areas
Support for init.d script parsing on bootup
A real busybox (with proper links) installed to /sbin (and therefore available to the system)
Undervolting and minor overclocking support (via SetCPU)
android ram_console support (useful for post-mortem of crashes.)
standard boot animation support
quicker charging with iphone chargers
Voltage and Clock Adjustments:
If you choose to tinker with the processor voltages and/or clock speeds, there will be no support in this thread. None. Yes, I'm using it myself, but I won't even support myself if I screw things up. If you find an issue with this kernel, BEFORE you post about it here, re-test after reverting all the voltage and clock speeds back to default. If it works with the default clocks/voltages, then don't waste your time or mine by posting about it to this thread. It's not supported. You can destroy your tablet by messing with the voltages and clocks.
You'll need a separate tool for voltage and clock adjustments. The one I see most frequently used is "SetCPU" (http://forum.xda-developers.com/showthread.php?t=505419.) I'm in no way affiliated with the author of that tool. You should be warned that SetCPU does not seem to be fully compatible with our tablets: There seems to be no way to bring up the menu in the program. If the program is "honeycomb compatible", this is likely due to the author making assumptions about screen dimensions on tablet devices (fairly common error.) Don't tell me about it. It's not my program.
ToDo:
Find source for the ethernet module and replace it (which will also allow adding more generic optimizations to the kernel.)
ethernet adhoc support (not really kernel specific, but not possible without the ethernet module...)
Figure out what samsung changed in the LA3 kernel (and didn't publish) so I can get the kernel working with the firmware update.
Known Issues:
Probably not compatible with stock firmware updates. (won't fix.)
NOT COMPATIBLE WITH LA3 FIRMWARE UPDATE!!
Flashing Instructions:
This is being released as an installable "update.zip" style installer. Stick the .zip file on your device, reboot into recovery, and install it from there. If this isn't enough information, please search and read the forums before changing your device kernel. (Flashing a .zip in recovery is a very basic skill that should be mastered early.)
Firmware Developers:
If you want to use it, please link to this thread and give clear indication of which version of the kernel you are including.
Legal:
This is based on the linux kernel, and therefore I'm including links to the modified source for the kernel (https://github.com/garyd9/linux_kernel_GT-P6210) and contents of initramfs (https://github.com/garyd9/initramfs_normal_GT-P6210)
PLEASE DO NOT MIRROR THE DOWNLOADS. IF YOU WANT TO REFERENCE THE KERNELS, PLEASE ONLY LINK TO THIS THREAD.
Change Log
20120128:
Support for iphone charger detection - pull up to 750mA from detected iphone chargers (1500mA from the samsung charger, and 500mA from everything else including a computer USB port.)
Testing USB "high current" charging. This is currently not enabled by default (and until I'm happy that it's stable and safe, I won't be documenting it.)
20120123: (actually posted on the 24th)
Minor adjustments related to the MMC and SD card interfaces (which includes the wifi interface)
Starting to pull in mainline kernel fixes (including fixes for some kernel panics/reboots.)
20120107:
disable mali state tracking. Doesn't seem to have any actual impact, but should reduce a small amount of overhead
add support for "reboot bootloader." Actually, the support was already there if the command sent to reboot was "download", but several android tools (such as "Quick Boot") want to send the command as "bootloader." This is only useful if you have a desire to reboot your device into "Download Mode" (aka "ODIN mode")
Replaced samsung j4fs.ko binary module with one built from sources. No impact other than easier to maintain.
20120105:
added standard bootanimation support (if bootanimation.zip is found in /system/media, it's used. Otherwise, the default samsung animation is used. Standard samsung music is played either way.)
It's now possible to tweak the conservative governor sampling rate down to 50,000 (default is still 100,000.) If done, this may make the tablet more responsive in some situations (however, there may also be a negative impact to battery life - everything is a trade-off.)
20120102:
added android ram_console support. After installing this kernel, if you reboot/crash, it should leave a file in /proc called "last_kmsg" that will show the last several kernel messages from before the reboot/crash.
20120101:
undervolting and overclocking support (only up to 1.4GHz)
If you decide that you want to overclock or undervolt your tablet, you are 100% on your own. You can easily fry your tablet's processor by messing with voltages and clock speeds. If you have issues with this kernel, remove all overclocking and voltage adjustments before you even bother posting on this thread.
Use "SetCPU" to change voltages, clocks, and governors. SetCPU can be found on the market and on XDA at the following link: http://forum.xda-developers.com/showthread.php?t=505419 (I am in no way affiliated with the author of that program.)
20111231 (initial release):
build compatible with stock ar6000.ko module
init.d script support
busybox in /sbin
cleanup of kernel config to remove excess debugging (when possible)
Frequently Asked and Anticipated Questions
Q: Will this work with the GT-P6200, GT-P6200L, or SGH-T869?
A: No
Q: Can you make a kernel for the GT-P6200, GT-P6200L, or SGH-T869?
A: I probably could if I had the hardware to test with. Without a sample of hardware, I can't even begin to guess if what I've done already will work, or what it might take to make it work. If you really want me to do one of those devices, please feel free to send me one. (Making a recovery kernel is quite a bit easier as it doesn't have to work with the ethernet, sound, modem or any other drivers.)
Q: Why doesn't this kernel include CWM Recovery?
A: On the GT7+ devices, the recovery boots from a completely seperate partition than the normal boot. When the device boots recovery, the normal boot kernel isn't ever loaded (and vice versa.) Therefore, it doesn't make sense to package them together.
Q: Why is the sky blue?
A: Please refer to: http://www.sciencemadesimple.com/sky_blue.html

I'm updating my tab in kies rite now before I flash this kernel. Your kernel should work fine? I know we can't update in kies once clockwork recovery is installed but I was wondering if kies will still recognize that I have a firmware update? I know that we have to odin back before we can update in kies but not sure about the other two questions, any help would be appreciated, thanks

Thanks Gary! Recovery is up and running and even made a nandroid. I located it to make sure everything worked (took a really long time). I see your framework zip wipes the dalvik cache and I was wondering if we have to wipe both caches before flashing the kernel? Thanks for your development! Much appreciated

What framework are you referring to? I try very hard to make the stuff I do "self contained", so if a cache should be wiped, it either gets wiped automatically, or there's a message displayed telling you to do it manually.
In context of this thread, there's no need to wipe any caches before installing this kernel.
Perhaps your question is in reference to something in another thread?
It was always a big suggested instruction on wiping both the cache and dalvik cache when installing roms and other things on my nexus s and vibrant so just thought it would be the same on my tablet

The framework zip I was talking about was the flashable zip you put together for the theme here in the development section.

A kernel is not a ROM, two totally different things and you don't need to wipe to install one. An easy explanation of the difference is a kernel is what runs the hardware (cpu, memory, etc.) and a ROM is just a UI (user interface).
With ROMs the general concensus on wiping is you need to do a full system wipe as well as wipe the dalvik cache if you are switching between ROMs, say from ROM A to ROM B but do not need to wipe if it's just an incremental update say ROM A to ROM A.1 unless advised to do so by the dev.
Awesome work Gary. If I had the knowledge to do this I would. Tab feels great.
Just glad to see some little development finally kicking off.

Glad you finally got things working.
Closed-source modules piss me off... Module versioning enforcement can get even some of the best devs (netarchy and I kept missing each other on IRC, it took a week before we figured out why his Infuse kernels wouldn't boot.)
Samsung is good about releasing kernel source in a timely fashion, but they SUCK at fixing broken source releases.
(Edit: WTF? They included BCM4330 source code in your release but NOT the Atheros 6k drivers?)
Edit: This might be useful, not sure - http://linuxwireless.org/en/users/Drivers/ath6kl
After lots of testing I do find its a little quicker! Don't know if its placebo but it sure feels fast. Nice work Gary. Recovery working great but the only odd thing I noticed was how long it took to do a nandroid backup. For a minute there I thought it froze up. All is good thought

Rooting hp slate 7 or 6 voicetab is very easy
Warning n.1 :- do not install any otas. Fotakill is uploaded for convenience
You will still receive updates after rooting
Many hp devices already have busybox, bash,swap support etc
you will need to install openvpn, sqlite, etc binary separately
rooting :- Root it through kingo root
While rooting your device may turn off and start charging, if it happens turn it on
The same will happen again
Turn it on again
Done! Rooted
If it didn’t work, try vroot
To replace vroot with supersu , go to http://goo.gl/r9uENy
Try cydias impactor as well
Important warning :- Don’t take any otas, especially if you have the hp slate 7 6102ra voicetab
The above method worked for me.
Tell me if there is any problem.
Vroot link :- http://goo.gl/sFnoCX
Kingo root link :- http://goo.gl/7vT35O
I will write a comprehensive guide to speed up these devices.
I have uploaded my modded build.prop you can check it once
Safe to install xposed
Safe to root
If you're an Indian user there is no update.zip to restore the device to factory state
Don't install update to KitKat on hp slate 7 6102ra it will brick your phone
Don't ask how to unlock bootloader. There is already a guide on xda-developers.com
Please support chainfire
You can support chainfire by installing supersu pro
No illegal activity
Please do not do illegal things with root.
If you intend to use lp, use it for legal things like DPI patches etc.

after root, there's lot work to do for this phablet
I'm curious, how to overclock it to 1.283Ghz? the SKU setting tell it capable to run till 1,3Ghz (*#*#4636#*#* method), I've tried modify its governor and cpu frequencies under /sys/ directories, it still refuse to run 1.3Ghz, the file revert back to its original state after I modify it
my device detail:
6002ra, 1.01.06 A, stock ROM Android 4.4.2, kernel 3.4.39, rooted, ART runtime.
Are you running on Marvell chipset or Marvell processor? Please read carefully this guide is for hp slate 7 6101 and 6102ra voicetabs and for slate 6 phablets.
There's an easier way to clock it.
Sorry but it's impossible to do it in root.
Luckily, I found a method :-
1 Open secret menu *#*#4636#*#*.
2 Click on Marvell testing.
3 Click on powersettting.
4 Turn powersettting service and power meter on.
5 Go to frequency setting.
6 Turn off dynamic frequency.
7 Click on set frequency.
8 Click on benchmark.
9 Over clocked to highest anything else requires a custom kernel.
I am not responsible for things like over-heating etc.
Over clocking vpu is a bit tricky I'll post a guide on that too.
If you want to know how to root a phone ask me
However you should take responsibility for anything that happens to your phone
It is safe to install xposed on these devices
See my other guide to root Panasonic eluga a
It is impossible to unlock bootloader. Don't try it

hi,
to tell you how to clock it, i will take example of the VPU (GPU)
after a lot of experiments , i found you cannot use the echo >> <xxxx> /sys/devices/platform/devfreq.vpu0/min_freq command but if you copy the /sys/devices/platform/devfreq.vpu0/min_freq to /sdcard, modify it and place it back to /sys/devices/platform/devfreq.vpu0/min_freq, it works!
to make a startup script
type cp /sys/devices/platform/devfreq.vpu0/min_freq /sdcard
modify it (caution - value should be equal to /sys/devices/platform/devfreq.vpu0/max_freq !) and use rom toolbox pro/free to create a startup script as follows
cp /sdcard/min_freq /sys/devices/platform/devfreq.vpu0/min_freq
or use
cp /sys/devices/platform/devfreq.vpu0/max_freq /sys/devices/platform/devfreq.vpu0/min_freq
i will upload a screenshot of my startup scripts when i get time.

please try going to developer options (these are hidden - google it) and select force gpu rendering, disable hw overlays, force 4x msaa and profile gpu rendering (caution - profile gpu rendering can cause negative performance if the graphics card quality is poor-it happens on my hp slate 7 voicetab
im sorry, i cant test on ART as hp released a buggy update.zip to kitkat file which bricks any device- rooted or unrooted. so i can't test on kitkat and xposed doesn't work on kitkat ART anyways
thanks, i have overclocked and found no heat. perhaps you are using a different device with a faster processor ? ill try to reproduce the problem at my end. if you are using greenify, uninstall it unless using xposed mode. i got a really hot phone (hot enough to cook my food) while using greenify in root mode but no problem in xposed mode

its not at all funny. the more you speed it up, the faster a task will complete. the phone can then go into sleep mode much more frequently-even when the screen is on. this means your processor will be sleeping 50-70% more if you increase clock speed which translates into a cooler device with much more responsiveness and better battery life. who says oc is bad for battery life? (unless you overdo it-be careful,my friend)
