[Galaxy Tab 8.9 SGH-i957 Android Development] modestone:
Spoken well.

From what I understand all he did was test out DaG's kernel for him and then make a post here about it anyways.

Not like he actually contributed any knowledge or know how, he was just in IRC when DaG was working with it.

The fact that he flies off the handle for no reason and deletes posts says a lot about him, and is not something we should look for in devs/contributors.

Ah well.

I feel like the original info in the first post is important to this discussion, and it is in-fact dangerous not to have it available to people reading this thread.

Therefore I went ahead and copied out the text from a cached copy of the page, enjoy!

*If DaG or any moderators have a problem with this, I will gladly remove it.

*Orlandoxpolice Since you have post #2 on this topic, maybe you should paste it in there so people browsing actually get the info that is needed?

THIS IS FOR THE AT&T GALAXY TAB 8.9 LTE SGH-i957.

IT IS NOT FOR THE 73XX SERIES TEGRA 2 POWERED TAB 8.9 MODELS.

It should work on rooted Bell Tab 8.9 LTE units.

Re-posting this in its own thread in the Dev section.

Huge thanks to Da_G for his work on this. Also huge props to the man, he doesn't actually have a 8.9 LTE to develop on, he did all this over IRC.

This requires DA_G's root kernel so you can use SetCPU, System Tuner, init.d scripts, etc to adjust the frequencies. Install that first.

The linked .tar file below needs to be flashed with Odin 1.85 in PDA, don't muck with any of the checkboxes or tragedy may ensue.

Obviously, this voids the f**k out of your warranty. You have been warned.

Exploring now to find top end limits.

If I get 2GHz going, I am going to be so pissed at you guys for kicking my Skyrocket's butt in speed... you owe me a screaming fast tab! lol

Here is link to kernel with 1944MHz max:

Note there are some files in ROM that limit your min/max speed and override sometimes, I have modded these for Croak but haven't put them in a nice package for you guys just yet.

Here are the raw edited files in zip if you are feeling adventurous.

adb remount

adb push filename.so /system/lib/

adb shell chmod 644 /system/lib/filename.so

And now.. sleeeeeeeep! Btw 1.93 was stable for a few benches but crashed after a while for Croak. might be heat dissipation problem! I imagine the SoC is nice and hot at that speed

Just keep in mind that the Skyrocket guys (using the same SoC as the 8.9 LTE) are getting 1.83 max stable overclocks, most are running 1.78. My results are from a sample size of 1, yours may vary.

Here's a few observations on my Tab:

1.89Ghz and 1.94Ghz on my LTE Tab is stable, but if you do repeated benchmark runs, it gets slower, which is indicitive of thermal throttling in action.

1.84ghz or lower is also stable and doesn't show signs of thermal throttling on mine, and is only a bit slower in benchmarks (about 100 in Antutu, 5 points less in Linpack Multi).

If your Tab locks up during Antutu testing, long press the power button until it reboots, lower the frequency, try again.

If you use this and the root, send Da_G some donation love if you can. He'd appreciate it, and it's good for your karma and cholesterol levels.
