[Transformer TF300T General] demandarin:
Lets get this overclock working for your 300 ;)

OK...lets try to figure this out and have a fresh start when attempting the overclock.

1) install the free app called root checker and it'll let you know for sure if you have root or not.

2)uninstall that ezoverclock app. afterwards reboot your device.

3)this is optional but i highly recommend it to cover all bases. Install the free app from marketplace called titanium backup. then open up the app. Make sure to allow superuser permissions of it asks. upon first opening it up it'll likely tell you that your SU/root binaries aren't up to date or missing stuff. Click on the option to let titanium fix this for you and get your su/root binaries up to date. if you don't see that message when you first open titanium, then your root is already good. just exit out of the app then. this step is recommended because alot of times, when rooting, pieces or files might be missing or the files aren't up to date. Alot of root apps might not work properly if those files aren't complete/up to date. titanium ensures you will have it all if you let titanium update your su/root.

4)now that you've made sure you have root and all its files are up to date, install the EZOverclock app again.

5)open up that app. A message will pop up asking if you want to give that app superuser permissions. click the tab that says allow. then check to see what speeds are defaulted to the different power modes, inside that app. Make sure at least your performance mode, within that app, shows 1.5 or 1.6Ghz. if it doesn't, click on that performance tab and set it to either number you want. once you do this, a message should briefly pop up saying super user permissions have been given to that app. even if you see those speeds set already, you can click on them again to make sure the message pops up with super user permissions given.

6)now exit the app and put your 300 on performance mode. which should be 1.5 or 1.6Ghz. as you just confirmed, in previous step, that your performance mode was set to either of those.

7)after that is done, open up CPU Spy. if you don't have it, download it from the market. it's free and this is the only true way to see if the overclock worked or not. once CPU spy is open, look and see if it shows either the 1.5 or 1.6Ghz as being active. if it does, then you overclocked now. if not, then go into CPU spy options and reset the timers. then refresh. then check again to see if those overclocked speeds are enabled. if they still not enabled, I'm not sure what else it could be as several others are already confirming this method I posted to work in overclocking their 300.

if that's not working. there's another thing you can try. uninstall that ezocerclock app. you can reboot if you want. then install an app called ATP tweaks. its in prime themes and app section. this is another overclock method but not as good as the other one because this doesn't let you change each power mode plus whenever device reboots, you have to go into this app and reapply the overclock. now when you first open this app, make sure to select tab to allow super user permissions. now in that app, on the left side you will see a turbo1 & turbo2. turbo1 is 1.5Ghz & Turbo2 is 1.6Ghz. choose which ever one you want. click on its little tab. now your performance mode will change to whatever speed you select. now flip 300 into performance mode & go into CPU spy again. check and see if either speed is finally enabled. hopefully it will be now ;) if so, you're overclocked.

A tip for Ezoceclock users: that app allows you to manually change what you want each of your performance Mode's speed to be set at. so for example, you can set balanced to 1.5ghz & performance to 1.6ghz. or whatever combo you want.

ENJOY!

NO. if you already updated and do a factory reset, IT WILL NOT revert back to .17 firmware. sorry buddy
