Have you got the "ADB" program somewhere on your PC?

Push is one of the commands.

If not, grab SuperOneClick from somewhere, it's in that zip.

It's a command-line app, so drop to a cmd.exe window (run as Administrator is recommended) and there's some in-app help, try adb -? or just adb by itself.

adb devices should show a list of connected devices (need to be in usb debug mode).

PS It's not good to connect more than one device at a time when using adb.

I loaded ntfs.ko via terminal emulator (using insmod). Verified using lsmod. Then usedany of the mount apps in the market instead of all these commands. Worked for me anyway.
[Galaxy Tab 10.1 Android Development] DC_MTP:
seems like the easiest way.. i downloaded terminal emulator

can you walk me through this? i have the ntfs.ko file already on my tab in data/local/modules folder
[Galaxy Tab 10.1 Android Development] RGardner:
Get USB Mass Storage Watcher OTG from the market. You'll use this to do the mounting.

See attached image for TE steps.When you type "su" at the first "$," you should get the "super user" permission window popping up as well.

Edit: I searched XDA and found the app I used to mount the drive here: http://xdaforums.com/showpost.php?p=13337600. This one I know worked with my 500GB NTFS HDD. The app I mention above I haven't used, but was told worked.
[Galaxy Tab 10.1 Android Development] joseph168:
Sorry for uneducated about this. Why we need to use ntfs.ko? What is the important thing to use this?
[Galaxy Tab 10.1 Android Development] RGardner:
You need the ntfs.ko module if you want to connect an external hard drive, thumb drive, or SD card which has been formatted with the NTSF file system. If you connect only FAT32 drives you do not need this module.

I have the latest firmware from sammobile for my P7500 and the previous pershoot kernel. I want to update to this new one, I have to flash the stock kernel and then the new pershoot kernel, am I right? My question is where can I find the stock kernel for XXKL4 ?
[Galaxy Tab 10.1 Android Development] DC_MTP:
will try when i get home tonight. so If i use the method from the link you posted I no longer need to do anything in TE correct?

just d/l apk posted and app from market correct?

Thanks for the simplification!
[Galaxy Tab 10.1 Android Development] RGardner:
I can verify it works... just did it at home. Curiously, I see the "USB storage blank or unsuported file system" warning, yet I have access to my drive, all my music, movies, on that 500GB ntfs drive.
[Galaxy Tab 10.1 Android Development] ensonic:
Hi all,

In Pershoot's kernel config I can see that Low-Level debug console UART is enabled on UART-B. Is UART-B TX/RX exposed on the 30pins connector ?

After i generate a boot.img, is there a faster way to test it rather than using CWM or odin ? How do you guys test your kernels when doing development ?

I wished I could use fastboot and directly send the boot.img via USB and have it executed on the target on the fly, but from what i understand retail galaxy tabs 10.1 cannot have fastboot ? I am unclear why it is possible to replace the stock recovery with CWM, but not with fastboot.

are the sources of fastboot available for galaxy tab 10.1 ? is it device dependent ?

there is no way for users with I/O tablets to extract their fastboot binaries, then retail tabs owners could somehow tweak CWM to execute fastboot ?
[Galaxy Tab 10.1 Android Development] Ziq666:
UTF-8 CIFS support?

Is there any nls_utf8.ko that can be used to get UTF-8 CIFS support for this kernel?
[Galaxy Tab 10.1 Android Development] vibecatalin:
If I can`t find the stock kernel for my firmware, is there anyway to update to the new kernel from pershoot? Except the method of reflashing the firmware again? Thanks
[Galaxy Tab 10.1 Android Development] agriff:
Yes, I've done a lot of searching trying to find the stock rooted kernel and have only come up with the solution of flashing your boot.img backup from nandroid. However, I can't get flashboot working on my 7510 wifi, making it quite difficult to accomplish.

It would be most helpful if some very kind person could create a stock kernel zip that can be flashed through recovery.
[Galaxy Tab 10.1 Android Development] Entropy512:
I think there was some issue with getting extracted fastboot to flash properly with Odin.

I'm not sure but I THINK it's possible to flash fastboot on a retail tab that was sold without an SBK lock via nvflash. I don't think anyone has figured out how to flash fastboot to an SBK-locked device.

The Tabs also have Samsung download mode (aka Odin mode), the problem is that Heimdall hasn't been updated to support the 10.1 yet, and flashing kernels from a Windows VM is annoying as hell. :(

It may be possible to flash kernels using dd - That has become common in I9100/I777 land thanks to the custom binary counter. I haven't had time to look into this - between the above annoyances and the fact that pershoot has done such a good job of kernel maintenance, I haven't bothered building my own kernel in months for this device.
[Galaxy Tab 10.1 Android Development] hamann:
I followed all your step and tried both mounting app and its not working. My tab won't access my external hard drive. I was wondering what kind of 500gb drive you have? Mine is WD 2.5" 500gb drive.
[Galaxy Tab 10.1 Android Development] RGardner:
I have also repeated the process with an old WD 80GB HDD, but the 500GB is a Toshiba.

Tell me what isn't working, and perhaps I can help.

Edit:

1) FYI - Get a better file manager if you're using the stock one. I used File Manager HD (it is free) and not the ****ty thing which comes with the Tab, which is basically useless.

2) I see a sub-directory called "Storages" under the mnt/sdcard. For me this is actually just a mirror back to the main /mnt folder. When I have a non-NTFS drive, I can access data via: mnt/sdcard/Storages/sdx (where x - a, b, c... based on the number of drives connected.)

3) With the NTFS drive connected, I navigate the root (The stock file doesn't allow this, which is why it is useless). Under there, I have mnt/sda1/(all my files).
[Galaxy Tab 10.1 Android Development] nightmarebadger:
@RGardner: Do you have an extra slot for power on your HDDs or does it power via USB when you plug it in? If it powers by USB, did you just plug it in or are you using a powered USB hub or something similar?

I thought you even with NTFS support you can't access HDDs that are powered via USB since the Tab doesn't provide them with enough juice.
[Galaxy Tab 10.1 Android Development] RGardner:
Correct, Tab cannot provide enough current for external HDD without additional support. So, I use a Belkin 4-port powered USB hub.

I know... this is a lot of extra cables, but it allows use of multiple HDDs, and bluetooth mouse/keyboard.

[Galaxy Tab 10.1 Android Development] vibecatalin:
Hello! Thank you for your work. This is awesome. Just one question, I saw that in

Bugs:

-Setting interactive as default governor (in kernel) results in cpufreq getting stuck.

Is that means that we should set the default governor to : on demand. ?

Thank you.
[Galaxy Tab 10.1 Android Development] pershoot:
The kernel does the setup for governor for you.

Ondemand is default (in kernel) and interactive gets set during boot up/runtime.
[Galaxy Tab 10.1 Android Development] kangfu84:
I just got myself a 10.1 P7510 and installed Galaxy Task 13.1 succesfully then tried to install this kernel through recovery.

Well, Dr. Pershoot... what's the diagnosis on the outputs?
[Galaxy Tab 10.1 Android Development] danielsf:
Hi pershoot, i am really sorry for asking these really stupid questions :-( but you said earlyer that the gpu can't be overclocked like the xooms can, is that because of a hardware difference or has Samsung screwed up the kernel? :)

Also, is 1.4ghz the absoult to the mhz Max out tab can go to at a perfectly safe voltage and stable as I have seen on YouTube many tegra 2 devices running great at 1.6 (even 1.5 would be incredible) . :)

And thank you or all you work on this kernel, its really is fantastic, I am so looking forward to voltage controlls. :-)

Example of tegra 2 at 1.55ghz: http://www.youtube.com/watch?v=vPlQxLEA86w (G2x)

Example of tegra 2 at 1.6ghz: http://www.youtube.com/watch?v=lAacIQpQOT8 (transformer)

Example of tegra 2 at 1.7ghz: http://www.youtube.com/watch?v=zXpi3vnTjhI (xoom)
[Galaxy Tab 10.1 Android Development] Grommish:
Pershoot has said in the past the 1.4 is it due to the fact the core requires more juice to go higher, which can do physical damage. Though I will say that I've yet to run into a situation that requires more than the 1.4 per core.
[Galaxy Tab 10.1 Android Development] mannequin:
although very stable, the OC doesn't help much - the flash videos are still choppy and slightly out of sync (anything above 480 on youtube, hulu, etc). and the keyboard lag is still there for me on Dolphin or Maxthon and various keyboards.
[Galaxy Tab 10.1 Android Development] pershoot:
For those fhat cant do 1.4, that's the luck of the draw. Not all cpus will be stable with what I'm willing to give.

Pls clock down to 1.2 or to 1g.

You can still run the kernel at your device's rated speed (if u can't do any oc), and reap the benefits of it without oc.

I will start on some uv.
[Galaxy Tab 10.1 Android Development] EvoXOhio:
What are the benefits other than OC?
[Galaxy Tab 10.1 Android Development] pershoot:
Various tweaks, performance enhancements, keeping kernel to current from various sources, extra functionality, some uv (when I start on that), etc.,etc.
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Gotcha.

When I had the XOOM, I was running the Tiamat kernel at the time. Once of the nice things about it was that something in the kernel fixed the nasty keyboard lag in the stock browser. Do you have any idea what that was, and do you plan on implementing it?

Thanks.
[Galaxy Tab 10.1 Android Development] joedon3:
I had an issue with stock that is appearing with this kernel as well. My Tab, although supposedly in sleep mode through the night will drain the battery to 0%. I appreciate the OC and the other improvements in the kernel, pershoot. But I wondered if this is something that you could take a look at? Anyone else having this issue?
[Galaxy Tab 10.1 Android Development] pershoot:
not sure there if there is anything i can do about that. that is really a framework/build issue. ill keep an eye out on it.
[Galaxy Tab 10.1 Android Development] pershoot:
if you have wifi set to never sleep and have lot of things refreshing, it will attempt to do this. but, it shouldn't be draining to 0.

check your bg apps first and foremost and ensure you don't have a rogue app running in the background eating away.
[Galaxy Tab 10.1 Android Development] SellswordShev:
really ? My tab is able to play 720p on youtube + justin.tv (via J Player) perfectly smooth even on stock 3.1. Ive still got choppiness in transitions/animations with this kernel (though I still need to mess with OC, haven't had the time for that yet).

@pershoot, I haven't seen any of the death sleep issues, I will try out OCing probably later tonight and see if I can make any of that happen. Thanks for the awesome tweaking :D
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Thanks man. I was surprised when the Tiamat kernel fixed it, because I figured it was something Google will have to fix. I'm not sure if the Tiamat guys state anywhere what they did to fix the lag, or if it is just a byproduct of something else they did.
[Galaxy Tab 10.1 Android Development] joedon3:
Doh! I didn't even think about the WiFi sleep policy. After flashing my phone for an entire year, you'd think I'd remember that. :-P Thanks pershoot!!!
[Galaxy Tab 10.1 Android Development] khanable:
Working well for me thanks
[Galaxy Tab 10.1 Android Development] MarcAntonyy:
I'm not a dev or anything - just a remora. But I have been following this thread and am planning on flashing this kernel tonight when I get home. I've seen people discussing the lag at the desktop and when swiping and it triggered a thought I wanted to throw out, even though it's likely elementary & not a relevant factor.

I'm rooted, running stock 3.1 and initially had a lot of lag at the desktop and when swiping, but it went away once I switched to Thumb Keyboard. I have SetCPU installed even though I'm not using yet and saw where someone said performance would be increased simply by switching to OnDemand, instead of Interactive. I set it and had instant lag at the desktop and when swiping. I rebooted with OnDemand set with boot and it persisted, so I reset to Interactive and it went back to silky smooth. Is there a known cause behind this behavior? I've never seen an OC kernel which didn't recommend OnDemand, so I assume there's a reason for it, but with the 10.1 at least, it seems Interactive provides for better responsiveness - at least as far as stock 3.1 is concerned.

Thanks so much Pershoot. Us remora's really appreciate your work.
[Galaxy Tab 10.1 Android Development] pershoot:
i solely use ondemand (default governor in this kernel), with some tweaks/amendments to tame it/be more responsive. it works well, thus far. swiping in launcher is smooth. everything is quite responsive. interactive hasn't played well in the past with high oc's, and i can only assume the same would fare here. i havent tested that particular governor out, as of yet, on this platform.

on first boot, your first swipe, first opening of app dock, first opening of settings (all launcher behavior), may incur a slight delay. but thereafter, it should be fairly smooth. this is because (i gather) it is loading in memory and caching. its an android thing, i s'pose. happens on my other devices as well.

i will probably further amend the governor as the weeks go on, as i make the rounds and sort the other things on the list.
[Galaxy Tab 10.1 Android Development] Tubes6al4v:
Great work per shot! I immediately noticed better stability over the preview. However, I did some cf benches and came up with:

Stock 11255, 3234, 6442

Preview Kernel on demand 12731, 3512, 7199

Release Kernel on demand 9471, 2699, 5407 (highest of 3 runs)

Preview Kernel 1.2/1.2 11255, 3234, 6442 (exactly the same as stock!?!)

Release kernel 1.2/1.2 11351, 3229, 6477

Preview Kernel 1.4/1.4 12957, 3212, 7110

Release kernel 1.4/1.4 13042, 3702, 7438

My evo w/ stock CPU setting: 4200, 1582, 2629 hahaha, not even close

So it looks like the release is more stable at those higher clock settings, but when using the stock min clock and on demand, performance suffers a bit. I would think this is related to the governer.

As always, please let us know if there is a way we can test, bench, etc in a manor that is more helpful for you!

[Galaxy Tab 10.1 Android Development] pershoot:
your evo is not using honeycomb. different platform.

make sure you are using the latest kernel offering (6/27 was refreshed at 10.30pm yesterday night).

set min/max to the same value.

now go nuts.

linpack,quadrant (not too reliable), antutu.

also as an aside,

im not developing this kernel with benchmark scores in mind. they mean very little in real-world. it is just a reference point.

new user pls help

Hi all,

new user here...

I have P7510 16gb, wifi only. I am a bit confused how to install this kernel :(

I’ve downloaded boot-cm_2636.4_ux_hc32-oc-xtra-vfpv3-d16_fp-010912.zip

And

lib-2636.4_ux_hc32.tar.gz

first of all, what is the difference? I see that lib-2636.4_ux_hc32.tar.gz

contains modules only, but should I install them? All of them?

I’ve installed boot-cm_2636.4_ux_hc32-oc-xtra-vfpv3-d16_fp-010912.zip from recovery and now I can overclock to 1.4gh, I’ve also changed the governor to ondemand. However the tab somehow feels slower with this kernel.. Asfalt 6 also seems slower despite the 1.4gh overclock.

Should I install all modules form lib-2636.4_ux_hc32.tar.gz?

I am a bit lost here,

pls help

thanks
[Galaxy Tab 10.1 Android Development] RGardner:
"Feels" slower? I've often wondered when I read that... how does one tell if a piece of electronics is "slower" (or faster) with one kernal versus another just by "feel?"

Benchmarking (for what its worth) suggests otherwise.

The lib file has a bunch of modules in it you may, or may not, want to enable (like ntfs.ko), but just sticking them on the Tab doesn't do anything except take up space.

[Galaxy Tab 10.1 Android Development] jeremysherriff:
Assuming you're flashing the kernel zip file in CWM it can't fail to install without CWM giving you some sort of indication.

Don't use ROM Manager or something to do this install, manually reboot to recovery and chose the correct ZIP.
[Galaxy Tab 10.1 Android Development] sambir:
Do i need to put CWM on the tablet? Does the stock recovery not flash the kernel? Can you provide me with the best recovery i can use please? So I guess that was the reason why the kernel was not flashing. I tried to install the kernel with stock recovery.

I installed CWM 4 and the kernel. Now i can see the kernelversion. It seems to be changed to preshoot but i cannot go further then 1ghz :S I still have root access.

OK solved. Seems i needed to install CWM and reinstall SetCPU. Thanks Guys :D
