Is it even possible to change the Japanese (!) version of the Sony PRS-T1, which is c

I own the Japanese model of the Sony PRS-T1.

Out of the box it was on original firmware 1.0.00.10050. Completely unstable, freezed randomly while reading or browsing the web, not usable.

Therefore I upgraded to the original Japanese firmware 3.1.00.18240. Behaviour has not improved noticeably.

So now I want to root the thing and switch to Android.

I do not know if this is imortant, but as a side note, I speak only little Japanese and want an Android in english.

I have tried to understand the information at these two pages [1][2]. Although I made several concentrated attempts, I simply do not understand most of it!

My main questions are:

1. Is it even possible to change the Japanese (!) version of the Sony PRS-T1, which is currently on the original Japanese firmware 3.1.00.18240, to Android, yes or no?
2. If it is possible, how can I do this?
