Hello,

for what i need exFat ?

system, data etc. are mounted as ext4 and external storage as vfat.

I am using kwbr Expresso ROM, all try with oc Kernels don't work. Kernel 0.4.2-oc was looping at boot, Kernel 0.4.3-oc hangs playing Videos, so I am now on 0.4.3-core-jb. My question is, what is the difference between core and stock in this version ? I saw core has more modules, like ppp etc I need, and boot.img in core is much bigger too, what is the differenz in the boot.img ?
[Galaxy Tab 2 7" Android Development] MonJovi:
kwbr espresso is based on P3110XXCLK7
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
1. For exFAT formatted SD card

2. Stock using Samsung's zImage/kernel, *core* using my self compiled kernel (have HDMI driver inside but no one tested it, I have no HDTV dongle to test it). Both using same initramfs, from Samsung tuned by me.
[Galaxy Tab 2 7" Android Development] karaern:
me either cannot understand the logic of extfat but its your kernel...:confused:

i am back to 0.4.5 enjoying the superior smooth and fast device....:cowboy:

sad that you decide to go to another way..
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
It's easy logic, compatibility! And most importantly, to mock Samsung. Samsung can not prevent me to reuse exFAT module that I have bought.
[Galaxy Tab 2 7" Android Development] travis82:
Do you have ext3 or ext4 support? If not you should add back exfat so we have large file support over 4gb.

I miss Thors Kernel on the Notes :( it had great compatibility.
[Galaxy Tab 2 7" Android Development] jaydyan:
This kernel is great, really fast and have no compatibility issues with my apps. Thanks for the great work.

[Galaxy Tab 2 7" Android Development] chazy chaz:
hey, i can't manage to make it work, i'm using the latest version of CWM and i'm on P3100,

if i flash it on stock ROM, it causes a permissions problem when flashing

if i flash it on CM10.1, it flashed just fine but caused me a bootloop

any ideas pleaaaase?
[Galaxy Tab 2 7" Android Development] Icegon972:
When i set them my tab totally crash then reboot.. Probably due to my i/o scheduler ? What are your settings about it ?

It will on work on stock rom. It will not work on cm10

I'm on stock 4.1.1
[Galaxy Tab 2 7" Android Development] paraiso-san:
I got rid of the kwbr rom and installed the stock 4.1.2 indian firmware. It still crashes in Youtube. I flashed everything right, could it be an issue of my particular P3110? I'm ready to give up... :(
[Galaxy Tab 2 7" Android Development] karaern:
mine is also p3110 eu version and never had youtube crashes, just litle hassle on 0.4.5 version but i can live with it.

just make full wipe from cwm: data+cashe+internal sd card...and install indian 4.1.2>cwm-official 0.6.1 or smth>root it(universal rooter or such)>start tab and configure it>flash kernel through cwm, each one after another:in a row(restart after installation of each part)>all must be ok...

it takes time but there is no logic not to work proper after this steps.:eek:

with 0.5.2 yourtbe is working pretty stable, but i prefer 0.4.5 because is faster ...:cool:
[Galaxy Tab 2 7" Android Development] paraiso-san:
I did all that, except wiping the internal SD. Could the problem reside there?

I use the Chainfire tool to root (http://xdaforums.com/showthread.php?t=1957160), then I install CWM with ROM Manager, and install each one at a time (wiping cache and dalvik with both modules).

When flashing with Odin, I only tick "Auto Reboot" and "F. Reset Time". Should I tick anything else?
[Galaxy Tab 2 7" Android Development] karaern:
i had real hassle with cf-auto, so i flash cwm through odin. my advice is to try by odin.
[Galaxy Tab 2 7" Android Development] paraiso-san:
This time, it manages to start playing Youtube HD videos, it can even hold tight playing for minutes in a row, but eventually crashes. Just by installing the OC module. I don't get it. I guess it's time to give up.

In every other aspect, it works flawlessly, even if I decide to OC it to 1.35GHz cpu / 384MHz gpu. It beats me why this happens. Other oddity: when I install the OC module, if I don't overclock and leave the CPU at 1GHz, the benchmark scores are much lower than without it installed.
[Galaxy Tab 2 7" Android Development] CooLoL1999:
OC?

Alright, where do I download the OC Kernel? I know its addon oc but is that it? Or do I need those core files?

Help please :D
[Galaxy Tab 2 7" Android Development] Icegon972:
You must flash the core files then the oc ones as you wish ;)
[Galaxy Tab 2 7" Android Development] CooLoL1999:
Setup

Sup PEOPLE! I just want to know what's your performance settings?

Thank You!
[Galaxy Tab 2 7" Android Development] Icegon972:
Cpu set to 1ghz with hotplug and row scheduler , gpu to 512mhz

Good response , great battery , and not a lot of heat .
[Galaxy Tab 2 7" Android Development] CooLoL1999:
GPU? How can I OC it?
[Galaxy Tab 2 7" Android Development] Icegon972:
Use these values :

echo 2 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_max_freq_idx
[Galaxy Tab 2 7" Android Development] CooLoL1999:
Edit: I just flash the GPU OC Add-on, right?
[Galaxy Tab 2 7" Android Development] Icegon972:
When you flash the gpu addon you have echo 1 = 384mhz gpu overclock. When you set it to 2 you get 512mhz gpu .

You can test your settings via Nenamark 2

[Galaxy Tab 2 7" Android Development] ketut.kumajaya:

[Galaxy Tab 2 7" Android Development] tapan15in:
I tried with exfat and is working good :) good job bro :)
[Galaxy Tab 2 7" Android Development] Caldair:
Awesome work! I flashed 0.5.3 Core and 0.5.3-addon-oc-noexfat on my p3113 stock 411. Everything is perfect here with no bugs! (Although I never got the same crashes in youtube as everyone else while watching videos. For me it would crash after closing youtube, and after some vids in the stock browser.)

Youtube runs perfectly, even overclocked @1.48ghz. Videos in the browser are also perfect, and gone is the instability that always followed watching streaming videos prior to v.0.5. Decided to try the non exfat because I don't currently use it.

Everything feels smooth and snappy oc'd, but most importantly it all now feels as stable as stock, even maxed out! (In the 1 hour I've run it for) I don't run benchmarks because they are BS and don't tell you anything usefull anyway.

Thanks ketut.kumajaya! I feel like if other users have the same experiences as I did with this that you have hit a significant milestone here.:highfive:

Cheers!
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Disabling Android logger is the easiest but a bad way to speed up our device but this kernel also has a good part related to media accelerator communication. Communication manager and RPC between main processor and media accelerator processor updated to omapzoom.org kernel 3.0.31 update. This update has a feature to boost the processor to the maximum allowed frequency (depend on governor max frequency) when needed. In theory, the result is faster media decoding! And by removing exFAT compatibility, we can remove a lot of kernel debugging stuff :D
[Galaxy Tab 2 7" Android Development] karaern:
hey ketut, you made my day. that i called improvement :fingers-crossed: custom kernel, for custom needs...:D

using 0.5.3 Core and 0.5.3-addon-oc-noexfat, all system running good in p3100, but got error when try copying data like movie into phone using cable.. in the middle of copy data, phone become blank and need to reboot... is this a bug or flash error??
[Galaxy Tab 2 7" Android Development] viktorlucky:
same with you, but my situation is in another way,

i just flashed 0.5.3 core and 0.5.3 addon-oc-noexfat, only 5 minute and i get my screen like freeze and blank.

reboot it and the problem come back again.

anyone can help me ?

this is my step flash this core,

wipe partition/dalvik cache - flash 0.5.3 core - wipe partition/dalvik cache - flash 0.5.3 addon oc noexfat - wipe partition/dalvik cache - reboot system

--------

i just downgrade to 0.5.0 core and 0.5.0 addon oc, but the problem come back again, it comes when i try to acces application that need root permission,

i,m using sungsonic HD n that rom was rooted.
[Galaxy Tab 2 7" Android Development] andreasl:
my tablet freeze with oc too, so I think not all tablets like overclocking.
[Galaxy Tab 2 7" Android Development] Icegon972:
I hope you will not leave this kernel for stock rom because of your work on the cm10 one bro :laugh:
[Galaxy Tab 2 7" Android Development] tropbel:
I flash 053 on stock fresh install of 412 fw all work very well.

Try my steps:

Flash stock fw with odin

Reboot recovery, wipe dalvik/partition

Flash 053 core, reboot

Reboot recovery, wipe dalvik/partition

Flash 053 oc addon, reboot

Reboot recovery, wipe dalvik/partition

Flash gpu oc if you want it, reboot

It should work

If it doesn't work try to wipe data before flash stock fw

With sungsonic rom i was experiencs many problems, so i decide to go back to 412 stock and flash this kermel 053, for me the best solution at that moment for p3100 :cool:

With cpu @1412 and gpu @ 512 i score 8800 on antutu bench

Benchmark a part, with this combination of fw and kernel you can set cpu @ 800 and gpu @ 384 and you will have a really fast tab with low battery drain;)

Thanks button if i help you :good:
[Galaxy Tab 2 7" Android Development] viktorlucky:
Thanks

Thanks for your solution. I will try that if next future I face same problem again after flash a kernel.

2 days ago I just flashed my tab again with sungsonic Hd, n now everything works well. But thanks again you try to help me out.

Juragan ketut, where is you? We miss you a lot. :D

2 days using kkboot 0.5.3 and oc with exfat. Everything works well. Until now I haven't faced bugs n issue.

Fast n smooth as usually, YouTube hd works like a charm.

Hi useing your kernal, great work, love the idea to swap internal memory for sdcard. whats the chance of also including xTweaks compatability with the next build? or making it change mpt to usb mass storage then i forget xtweaks really miss UMS on my devices, I have media players that don't see MPT but fine with UMS.

I use this kernel with kwbr Expresso ROM. I had no problem with both v. 0.52 and 0.53. OC 1.35GHz, 512 MHz gpu, interactive governor, everything is smooth and fast.

My apology about the i/o scheduler problem - it was actually the problem of Dolphin browser. The newest versions of Dolphin do not support Adobe flash but you can hack it to work. It seems that it does not completely work afterall.

AW: [BOOT IMAGE][GT-P31XX] KK-Boot - Custom boot image for stock 4.1.1/4.1.2 ROM

Hi together!

I apologize for my noobish question, but I like to know which kernel is the best for stock 4.1.1?

Something else would be if I need any of the addons?

Thanks in advance!

Edit: I flashed the latest Kernel (5.0.2) and oc add-on. Everything works fine.

Antutu gives me with oc 1.34 Ghz around 8100 points. That makes 1000 points more than stock kernel :D

i got "unfortunately video player has stoped" error when viewing available movies and pick one to play, but if i open video player widget (already played a movie before) then it played fine, i can also tap on next video and played fine, force closed only when playing video from video list.

i don't know if its because i'm zipaligned my video player apk or not, can someone post un-zipaligned video player apk?

edit:

just tried skype video chat also, my tab just reboot it self

EDIT2:

video player error because minimode.jar is renamed, tried skype video works fine but after reverting to KK BOOT 5.2 No-OC, did not test OC version with minimode.jar exists
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:

I really miss Samsung keyboard. Back to stock and then repackage my landscape kernel for CM 10.1 (without compilation but need different ramdisk), I got landscape lock screen, touchscreen and orientation sensor works :good: but a really mess Samsung boot animation :( So, the conclusion is we can reuse CM 10.1 kernel for stock ROM without any problem, we can use single kernel to boot stock ROM and CM 10.1 . Do not try to boot CM 10.1 using stock kernel, already tested it and I got a really slow graphic updates!

Wrong icons and menus orientation in camera app, no problems in preview orientation:

Landscape kernel for stock JB 4.1.x, to complement Xposed Framework + Xposed Tablet UI:

blackhawk-kernel-0.1-landscape-p31xx.zip (~14MB)

BUG:

1. Samsung boot animation not work as expected. Nexus 7 boot animation included

2. Wrong icons and menus orientation in camera app, camera preview working properly. For me this is just a small bug in order to restore my ICS experience :)

Before switching to another kernel, you must flash:

blackhawk-kernel-0.1-portrait-p31xx.zip (~14MB)
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
I want to prove we can use single kernel source code for stock ROM, CM or CM based ROM, and Ubuntu Touch for both P31xx and P51xx device target. Wait for it... Dual boot just a matter of my will and a patch for my kernel source...
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
For those who still have problems with Youtube HD, can try blackhawk-kernel-0.1-portrait-p31xx.zip. This kernel does not have Samsung MTP support, as taken directly from CM without recompiling.

just read it and imagine it.. oh that was really amazing kk..

sir, my apologize if i ask you this, are you ever try to copy data more than 2gb to your device using cable?,

i'm using your 0.5.3 kernel with overclock no exfat,

if i copy a data less than 1,5gb sometimes i dont faced a problem like my tab reboot or hang and sometimes i faced it,

but if i copy data more than 2gb, i faced that my tab hang and reboot by himself.

please guide me to solve this problem.

i think some user have this problem too,

thanks again for your kernel,

Q: what new does 0.5.3 kernel include.?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Just a reference but not a final conclusion:

"In many implementations the problem was exacerbated by treating the sizes as signed numbers, which further lowered the limit to 231-1 bytes (2 GiB-1)." http://en.m.wikipedia.org/wiki/Large_file_support
[Galaxy Tab 2 7" Android Development] am05mhz:
yeah, i realized that when i saw the shrunk button, then try to restore my minimode.jar and see if that works, and its indeed because of that.

when i still on ICS, i removed miniapps arrow button, and stock video player running fine. I guess ics stock player does not have shrunk button.
[Galaxy Tab 2 7" Android Development] paraiso-san:
Thank you! This is the first OC kernel that works for me in TouchWiz ROMs! All the others made Youtube and streaming video crash the tablet.

This is great because I recently switched back from CM 10.1 (where I used your kernel too) to TouchWiz, because I missed some of the eye-candy and exclusive features of an official ROM (the floating apps, S-Planner, Samsung's photo and video editor, Samsung contacts app, better camera app, and so on); I will get back to CM when most devices start shipping with Android 4.2 and Samsung don't release an official 4.2 ROM. The only thing lacking for me in an official ROM was overclocking (specially the GPU that is underclocked in the official ROMs) and now you've solved it, and no more Youtube bug at last :) Ketut, you did it again, you gave new life to my tablet without resorting to run CyanogenMod :D

0.5.3

I don't know why but every time i try to download something from Play store or Google Drive my tablet reboot.

im on 0.5.3 with OC addon
[Galaxy Tab 2 7" Android Development] paraiso-san:
Ketut, just noticed that, for the same clockspeed, the Antutu score is about 1000 points lower than in either CM 10.1 with your kernel and with stock ROM with your 0.5.3 OC kernel. Other benchmarks such as Smartbench 2012 show the same behaviour. Any ideas why?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Power Manager might try to limit the maximum frequency at 1.008GHz but my kernel performance still better than stock and power consumption is still quite good.

0.5.4 is coming soon, it will use source code from my github. My question is whether exFAT support is still needed?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
I have never experienced anything like this.
