What can go wrong when flashing an unstable Android OS onto a phone? Is there an easy way to reset the phone if something goes wrong? Has anyone out there had experience flashing Android OS?

Why would I want to flash Gingerbread 2.3.3 aka Leaky onto my Samsung Epic 4G?

One benefit that I can see is that users of the Epic will be able to test their applications on > Froyo 2.2.1, which is currently the stable release for the phone.

EDIT: Also, what happens when the device wants to update again, say 2.3.4 is flashed onto the phone, and then Sprint finally releases a stable 2.3.4 in 2013. Assuming I still have this phone then, will it upgrade gracefully from the flashed ROM?

Questions that ask "in your opinion" are generally not the kind of questions we're looking for here. The kind of questions we like have (the potential for) a single, concrete answer. – Al E. Aug 4 '11 at 20:07

"Is it a good idea" is still asking for opinion. – Al E. Aug 4 '11 at 20:22

Anything can go wrong, including issues that permanently brick the device.

That said, Galaxy S devices are compatible with a tool called Odin that can fix all but the worst problems. Example process.

I personally flash pretty much anything I feel like onto my Vibrant, and Odin has saved me many times. I wouldn't hesitate to flash something I wanted to try out, but you may wish to be more cautious.

Can't emphasize enough that for the phone the question is about (Epic) bricking is significantly low-risk. See instructions on XDA for details. – TREE Aug 5 '11 at 12:10
Also, 2.3.3 might not add much, but the more recent 2.3.4 leaks are supposed to allow for google video chat with the front camera. That's huge. – TREE Aug 5 '11 at 12:11
