Re: [Q] A dumb question.
Yes, Samsung released ICS 404 for the device. Download the relevant files from Sammobile. Assuming you already have the samsung drivers installed on your pc and you have odin 1.85 too on the pc.
Extract the content of the firmware
Boot your device to download mode by simultaneously pressing and holding down power button and volume down the recovery and download modes appear.
Select the download mode by following the instructions.
Once in download mode, connect the device to the pc but ensure that odin is already opened and that usb debugging is checked in developers menu.
When your device is recognised, you will see yellow colour on one of the boxes in odin.
Click on pda and browse to the folder where you extracted the content of the zipped firmware, click the file and in odin, click start.
A green pass will be displayed on the box when the upgrading is successfully done.
Disconnect the device and it will reboot.
When it boots up, you will be on ICS. You can confirm from About Tablet in Settings.
Regarding installing CM 10 or 10.1 Jellybean, you will need to root the device first before you can apply any custom ROM or firmware.
