Samsung Galaxy Note 2

If I root it to install CM10, is it possible to go back to stock to avail warranty?

Yup, you can go back to stock anytime using ODIN and the firmware from sammobile.com.But I don't know if the Samsung service centre have any techniques to detect firmware tampering.

Can you help me in rooting and installing CM10? Any links?

Here's the XDA link for Note II. You'll have to first read a lot before doing anything.

I would suggest staying with stock ROM as you'll loose some features like their 'S' apps and more.

and technically, warranty as well.

But it can be restored with restore of original firmware isn't it? With Sony, it's not possible as once you unlock bootloader, it erases DRM content and few Sony apps like TrackID stop working even if you restore factory firmware and relock bootloader.

Any such funny business with Note2?

well technically, the phone has a counter which keeps track of unsigned firmwares being installed. currently, your counter is at 0. as soon as you flash an unsigned kernel/ROM/Firmware, it will increase to 1. it wont go back to 0 on installing back an original firmware. You'll also get a triangle with an error message on every boot. Although that triangle can be removed with an app called TraingleAway. On the original Galaxy S, even the counter could be reset by using a JIG cable. Not sure about the Note II. Maybe there is some method for that too.

But from all I have read at xda, Samsung guys haven't denied anyone warranty for installing custom firmware etc. Even when there was a leaked kernel with the eMMC bug for the Note I which if you flashed basically killed the phone, most people posted that they gave the phone for RMA and the motherboard was replaced even though technically, it was their fault.

But no, you won't lose any functionality(apart from the proprietary Samsung apps) and the triangle on booting on doing all this.

EDIT: just checked, TriangleAway can reset the flash counter back to 0 as well, so you should be fine.
