Karbonn smart tab 8 and 10 rooting and memory swaping

Your warranty might get void if you root.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.

Ok so now that you've read the disclaimer I'd like you to know that I have only discovered the rooting technique for our ST8 & ST10. It was actually made for Ainol Crystal but with my research and knowledge I realized that it should work for our devices as well. This thread is to keep all developments for ST8 & ST10 at a single place.By editandroid.blogspot.com

Rooting:
Download the Crystal_Root.zip from  here and copy it to a microSD card (do NOT extract it)
Charge up the battery in your Crystal, Power Off and remove the charger cable.
Insert the microSD card into your Crystal
Get into Recovery mode.
In the recovery you can move with the Volume- button, you can select with Power or Volume+
Select the apply update from EXT option
Select the Crystal_Root.zip, this will install the package
Wait for the update to finish
Select reboot system now

This is a tried and tested method and has worked for everyone till now.

Swapping External to Internal Memory

The fact that our devices have only 1.51 GB of Internal Storage limits the capabilities of our devices. Especially with HD Games. But after swapping this won't be a problem anymore.
Download the file Vold.rar from here.
Extract the file vold.fstab and paste it to your SD Card.
Now with ES Explorer Mount RW as writable and tick up to root(You have to root and have to know how to move into root).
You should now be able to access the root.
Copy the vold.fstab from Sd card.
Press back and paste it in system\etc.
It will ask you to overwrite. Allow it to do so.
Reboot.
I myself have tried it and it worked wonderfully.
That's it. Enjoy HD games now.
If you want reverse your swapping then download revertvold.far from here
And use the same method

Lag-free Tweak

Install SetCPU app
Download the file Setcpu.txt from here
Paste it into the root of your SD Card
Open SetCPU, first change the governor from "conservative" to "performance2"(This is the most important thing)

Click on options button(three dots) and then click Device Selection
Select Custom Frequencies
Now Set Min frequency to 48 MHz and Max frequency to anything according to your preference(Now you'll have the choice of setting the frequency upto 1.5 GHz)
When you wan't to conserve more battery lower the Max Frequency(while browsing or listening to music maybe) and when playing HD games up the Max Frequency(Most games will run perfectly with even 1200 MHz)

Note:-48MHz of Min frequency will give more battery in in standby mode.
And now you call play games like Dead Trigger on Ultra High graphics settings without lag on 1.4 or 1.5 GHz.
Try not to Clock the CPU above 1.2 GHz for a long time as it could cause heat issues. The governor itself should speedup everything for you.

Enjoy.
