Should I upgrade firmware of KPW1?
I have a kpw1 running 5.3.0 and I found the newest version available is 5.6.1.1
I know if I upgrade it to 5.6.1.1 before jailbreak, I'll never be able to downgrade or jailbreak it again unless I use the serial port method.
What if I jailbreak it before upgrading? I found some posts saying jailbroken kpw1 can be downgraded. But I can not find the detailed steps for kwp1.
Anyway, what's new in 5.6.1.1? Is it worthy to upgrade to it?
And is it possible to install another systems such as duokan?

Jailbroken devices can be downgraded using the diags boot partition and judicious use of `dd`. So it's *possible*, it's just a pain and if you accidentally type the wrong device you can brick your Kindle.

For example, the instructions on reverting the PW2 to fw5.4.0 -- http://ixtab.tk/kindle-touch-images/PW2/README.txt

Someone might trade a pre-5.6.x PW1 for a 5.6.x PW2 on the flea-market.
