Original Post Gone. Formatted and tweaked original instructions. Original post by Croak can be found quoted at the bottom of page 8. Please read entire post before asking any questions. All credit goes to Da_G.

This is ONLY for the SGH-i957 and SGH-i957M (Bell).

WARNING: THIS WILL TRIP YOUR FLASH COUNTER [aka VOID WARRANTY]

NEXT WARNING: USE OF ODIN CAN DAMAGE YOUR DEVICE IF USED INCORRECTLY. WE ARE NOT RESPONSIBLE FOR ANY DAMAGE DUE TO FOLLOWING THESE INSTRUCTIONS. PROCEED WITH CAUTION.

Steps:
1. Download and Install the Samsung Drivers for your device. Install Kies, or the latest mobile drivers.

3. Download Odin 1.85

3. Open Odin 1.85 as administrator
4. Place the OC kernel .tar file in the PDA slot. (Make sure you do not have any boxes in the options panel checked besides the ones that were checked when opening the program - should only be auto reboot and f.reset time)
5. Place the tablet in download mode. Hold vol up + vol down and hold power until the device powers on into download mode. Hit volume up to proceed after the warning screen
6. Plug the tablet into the computer on a main usb slot and it will be detected by Odin in one of the ID:COM slots (will appear as yellow)
7. Hit Start - the OC kernel should will be flashed to the tablet. Tablet will restart.
8. Go into market and download NoFrills
9. Set Max. Clock Freq. to 1.728, 1.782, 1.836, 1.89, or 1.944 GHz. Set your min clock speed to 192 MHz if desired. If you run into problems, set your I/O scheduler to noop instead of cfq. DO NOT CLICK 'APPLY ON BOOT' UNLESS YOU HAVE THOUROUGHLY TESTED THE STABILITY OF THE DEVICE AT THE SET GHz!!!

If you are unhappy for any reason and wish to go back to stock kernel - you can flash the stock kernel back using steps 3-7 above with the below file.

If you are still experiencing instability at any speed above 1.566 GHz, there are certain .so files (libhardware_legacy.so, librpc.so, and libtalk_jni.so) which limit speeds and can override the OC sometimes. Da_G modified these files which can be pushed to the device through adb commands. I won't explain how to get ADB working, it can be found on XDA elsewhere.

Well I seem to have pretty thoughly bricked my poor tab.

Without going into to much detail, I should be more careful with .pit files and ODIN heh...

The tab itself appears totally dead, no boot, no back light, no matter how long you hold the power button / vol button combos.

When you plug it into a computer, it shows up as QHSUSB_DLOAD, and cannot find a driver.

ODIN and HEMIDALL don't see it at all.

I managed to find a QHSUSB_DLOAD driver of some sort, and using QPST was able to see that it was a com port, but I can't do anything past that.

Any of the tools in QPST say they cannot be used because the device is in download mode.


Anyways, pretty sure its gonna have to go to samsung to be fixed.

Which blows, because were pretty sure our next test will be successful, but of course who knows
