Hi all,
I'm with an X8 having nAa's 2.6.32.61 jb kernel and MiniCM7 2.2.2. S2E is my sd-ext manager (SD is a class 10 Sandisk Extreme 60 MB/s). I cannot get the BT working. I have an indication for on/off, I make it discoverable, I try to scan, but I get nothing or random erratic behaviour (mostly FC/W, occasionally mac addresses instead of device names, once a device name), but never succeeded in pairing and connecting to anything. How can I get the BT working? It used to work on stock kernel/ROM and on stock kernel/GingerDX v031b, and I would rather consider it a SW glitch than HW. Kernel and ROM were flashed/installed strictly according to the instructions in the relevant threads here. The X8 works OC'd to 768 MHz (no UV) with a performance governor, but I've tried at stock speed (600 MHZ) with an ondemand governor - no difference.

Hi
I use Badass kernel
and it always isn't stable
sometimes freeze , somtimes reboot ...
and in 652 maximum frequency , camera dosen't work
Can someone help me?
I/O
and my I/O sheduler is SIOPLUS
CPU GOVERNOR : SMARTH.3
CM10.1
Its a known problm with kernel as stated by alin.p himself..oc device is just a workaround not a complete solution and many features (like camera) doesnt work after oc..so stay cool n check the original thread for updates ..
so , will it be solve ??? does alen.ph know this problem ????
Of course dude...in fact he is planning to make kernel specifically for fit
My Dhollmen kernel.
Galaxy Tab 2 P51xx : STOCK ROM compatible.
Sources in GitHub: https://github.com/Dhollmen/Espresso-Kernel
Credits for Kernel Team, Google, Samsung, and anyone with merit.
Linux kernel 3.0.101 version.
Developed specifically for Stock Rom.
Cpu boot at 1216 MHz.
Gpu boot at 384 MHz.
Undervolt.
Boot with 'pegasusq' as cpufreq governor.
Boot with 'sio' as block scheduler.
CPU overclock selectable up to 1460 MHz.
GPU overclock selectable up to 512 MHz.
Last ducati-m3.bin firmware included.
Without debug code.
SElinux Support.
Activated ZRAM with LZ4 compression
Tweaked Init process.
Android F2 File system (F2FS) support.
Union File system (AUFS) support.
Windows NTFS support.
Windows CIFS support.
Unix/Linux NFS support.
Windows exFAT support.
Apple HSFS and HSFS+ R/W support.
Manages /etc/init.d/ and /etc/sysctl.conf.
Init's improvements built in kernel.
Compiled with Linaro 4.7 toolchain.
I think it does not need further sysctl.conf tweaks.
GENERAL NOTES:
Booting pegasusq because it is very soft with frequency scaling and looks as good compromise between performance and battery saving.
User can insert boot actions by scripts in /etc/init.d. Here, it is important to establish execution's order, starting with numbers script names,
to run always the latter that has the largest number.
With this kernel, the user not need a separate script to run at the end of the boot.
Has been included an interface to the OC of the GPU, using "cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_frequency"' command to view current frequency.
Kernel will stop secundary processor when its performance is not necessary for the functioning of the tablet.
The second processor still remain stopped with low power requirement, even the first reaches 600 MHz.
Reduced the working voltage used by the Core, GPU, and CPU frequencies up to 1216 MHz.
Completely replaced the memcopy & memmove functions code for memory data movement. The new code can be up to 10 times faster.
Releases for GT-P5100 and GT-P5110/3
Releases for Jelly Bean 4.1 and 4.2.
Go to Dowload
CHANGE OC OPTIONS BY HAND:
Code:
# GPUFREQ --> X = 1 (384 MHz) || 0 (307 MHz) || 2 (512 MHz)
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
# CPUFREQ --> X = 1216000 || 1008000 || 1360000 || 1420000 || 1460000
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
# SCHEDULER --> X = row || cfq || sio
echo 'X' > /sys/block/mmcblk0/queue/scheduler
# GOVERNOR --> X = pegasusq || lulzactive || interactive || hotplug
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

This rom? http://forum.xda-developers.com/showthread.php?t=2783989
No because I prefer android 4.1.2 . However the tab remains with the sentence: "Samsung Galaxy Tab 2 10.1". I feel the boot sound but the tab doesn't boot and remains the sentence "Samsung Galaxy Tab 2 10.1"
Just want to say this kernel makes my device a proper tab 2 with 4.2.2. No lag just smooth.. thanks OP!
@tuxafgmur, if you want I can test 4.1 kernels for you
@tuxafgmur, send me a link to download by pm when you will do the next version. I will test it.

Hi mate,.. tried to flash this on my stock 4.2.2,.. but flash failed,.. I think its something to do with the assert lines,. do I need to change / modify the Updater Script ?
If so, can you pls explain what is required

If your device is GT-P5100 then you must download p5100 file, else (your device is GT-P5110/GT-P5113) you must download P511x file.
I think that's your problem. Please, not change nor remove the assert lines.

Edit,.. Thnx Tux,.. all good now now,.. great work, !! I've been running Kitkat,. however I like the stock UI,. and now its OC'd its much smoother etc,..
cheers !
have anyone tried and tested on 4.1.2 ?
Hello,
I need some help please: the device (P5100 in my case) needs to be rooted and a new (modern) recovery installed or it works with stock recovery?
My TAB was previously updated to stock 4.2.2 (which I like it and used it for 5 months btw) without any other modification until now; and with your help, a little boost to it will be more than welcomed...

Thanks, however I'm trying your kernel with zap blaster 2.3 rom and it's fantastic , now I can use 4.2.2 well. Thanks for this fantastic kernel
Nice work indeed, thank you very much for a better kernel.
A little problem (on my P5100 at least): when using videos from youtube, after some suspend/resume/switching tasks, videos would lock up and wont play anymore, just black screen. I think it's because 900mV for 300MHz is not enough for my CPU. Is there a way to change that default boot frequency table to 950mV? I changed it with VoltageControl you mentioned above, and it seems it's working with the new settings, but I don't want to use an application at boot time, I just want to be the default 950mV for 300MHz. Where do I have to look?
sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table*is changed when modifyed with VoltageControl, but reseted always to 900mV after boot.
Thank you again.
I really like this kernel!
Makes my son's Tab2 faster and snappier.
Please dear @tuxafgmur have you considered to update it anymore? :fingers-crossed:
Thanks in advance mate

Hello again,
i have installed the 4.4.4 android version but the tablet has many issues. It stucks on every move. Can i downgrade to a lower version?
I've flashed this fantastic rom and everything goes well, sometimes there is a little bit of lag so I've tried to change some CPU and GPU parameters to improve the reaction of the tablet but afterthe flag on the "Mali use VPLL Clock" in GPU settings the tablet didn't reboot anymore, "freezed" on black screen after the samsung logo....why it happens?
I had to put the GT in recovery mode and reflashed the rom and gapps to reboot it
someone can tell me what are the best cpu/gpu settings for a good per performance of my GT?
deleted omniswtich...reduced abit of noticeable glitch
WATCH OUT WORRLD!!! UR NEW ANDROID 2016 WILL BE DONUTS & TART...!!!! Or was it donuts or tart...? ��
O heck! Not sure which one works for ya'll but I'll go for STEaK!.. gotta looooove steak mannnn....its good for 'steak'-out..... ��
If ur dad's a cop, don't tell em I said dat ��
::::
Too much performance hugging apps.. Reducing Google service related apps..sheesh! Why can't an app run only when its opened at a time?.. GMs core should learn to relax...maybe I should pour it some grape juice...
is this the end of omni ROM for tab 7.7?
Will omnirom move up a step into the new lollipop? I'm very curious what omnirom would or could become.....

Kernel with diag mode
Hi, i have 5.1
This kernel has diag mode? Ty:good:
Is a sale for kcontrol app planned?
Or is there any way to enable sweep to sleep without an app?
Dear Bricked kernel Developer and Pro consumer
Excuse me. I am novice(beginner).
Q1.
when released next stable version?
(lastest stable version is 15/03/23)
Q2.
I use stock rom 5.1.1(LMY48B) & stock kernel after format.
I will use
LMY48B stock Rom and Bricked stable kernel(15/03/23)
This combination is good harmony(stable?) ? OR Wait next stable version??
Q3.
I love bricked kernel and KControl.
Because many smoothness and High performance.
I think that default settings are High performance and high temperature.
Did you recommend me between battery and performance balance settings?
I don't speak english well.
Excuse me.
Thank you for reading this thread.
Dear Bricked Kernel Developer
Will You update The kernel to 5.1.1 sources ?

I cann' t speak for @show-p1984 but here is what I think.
Q1. Next stable might be when android M gets released.
Q2. Yes it should work on 5.1.1. Do not try on android M as it won't work.
Q3. I use following settings
Low Freq 96 Mhz
High Freq 2265 Mhz
Governor Conservative
Touchboost On
Run queues to hot plug 15, 30, 40
Run queues to unplug, 10, 15, 25
Undervolted to 700mV
Get good performance and very good battery life.
Thank you very much.

Unpack and flash with Odin:
G386FXXUAOA1_G386FPRTAOD1_PRT 4.zip
Added: 20.12.2015
I decide to clean this post a bit. If You need only kernel, simply unpack it from G386FXXUAOA1_G386FPRTAOD1_PRT 4.zip
Hi Agasharr,
Overclock 1.46 GHz working fine with your G386FXXUAOA1_G386FPRTAOD1_PRT.zip !
What's next ?
Thanks !
Hi, in next kernel i'll add:
CPU Governor (userspace, smartassV2)
I/O Scheduler (sio, deadline)
Added:
smartassV2 had some issues (running always at max speed) and was removed
lulzactive seems to have same issue, it's still in kernel but i'll probably remove it

Nor am I. But i see no sense in including all of them. Mostly there are based on Ondemand, Conservative or Interactive (as described in link You provided). So it's a matter to choose the best of it's type and tweak the settings to our device.
@Agasharr I agree with you, I ignore which is the best for us. By the way, this list may be outdated since 2012, maybe some new governors exist now ? @benplay G386FXXUAOA1_G386FPRTAOD1_PRT 2.zip flashed OK today with odin 3.10.6 for my French G386F too.
New kernel uploaded, cpu overcloced to 1,612 MHz.
Added nightmare governor.
Phone is stable, but running few benchmarks makes it definitely warm.
Maybe it's time to make http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385
Antutu score rises to ~18700.
As some kind of summary (the left side, in green, my g386f with the latest kernel, the right side is "average" g386f from Antutu database)
Hi Agasharr,
With overclock 1.612 GHz, I get Antutu score 19246 with ondemand governor.
I guess next step is upgrade to Android kitkat, isn't it ?
Thanks !
Hi stefguer.
I wish it could be possible. But seems that no one can hack secure boot of g386f.In fact it's reason I named this kernel "last hope".
Shame for secure boot. What is your next upgrade then ?
I've some ideas if they work I'll let You know. But don't expect anything soon. Especially with such enthusiastic feedback I'm getting now
btw. inspired by the http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385
I decided to make something with this additional heat from overclocking, i used termopad to transfer heat to more areas, 1 mm thick is max that can fit, if someone would like to try something similar I advice 0,5 mm
You gave me hope one more time in the Galaxy Core LTE !
However I have some questions... I'm not pretty good about android and the developpement of it and after and afeter reading many tutoriels I don't succed in getting mu boot.img : so how do you made ?
Hoping one day my phone will be with Cyanogen ^^
Hi, You want to flash kernel?
If so download G386FXXUAOA1_G386FPRTAOD1_PRT 3.zip
from the first post, unpack and flash it with odin (tool to flash samsung's firmwares)
If You want to prepare own boot.img just to be sure it's safe. You need to download samsung firmware (same version that is in your G386F), and follow the procedure described in the opening post.

Nice ! Well, i think i won't try your kernel since my battery is not really in a good state and overclocking would make it worst, but do you think you could add OTG support in the kernel ? It seems the material and rom are OTG ready ('drivers' etc) but the kernel isn't
