Ok i read this guide a few times : http://www.ps3hax.net/showthread.php?t=39766

(I'm beginner/Noob Out of the box./ recently found out about this E3 Flasher)
Now i may have posted similar threads like this all over the place. i'm just a bit stubborn i want to be fully prepared B4 i purchase a E3 Flasher 2 downgrade my PS3.

So far i know:

my PS3 can be downgrade 2 3.50 - Lowest

My console Model id is CECH-2502B

Date Code 0C

Supports E3 Flasher
..........................................................................................................

Now For the last questions B4 I go an Purchase an E3 Flasher:

Now people say that you can only downgrade from 4.20. is this true?

others said you can downgrade from any firmware (4.30/4.31) is this true?

and i was thinking of getting it around the time my summer holidays starts so that's in about a months time.

So if Sony were to release a few updates by then like 4.35 or 4.40 Will i still be able to downgrade? (to 3.55?)

and this still nag's me. will the downgrade files or (process - Meaning the steps take in downgrading) need changing to suite the new firmware (4.35/4.40 if Sony release them) - What i mean will i still be able to use the same old files used in 4.20/4.30 to downgrade from 4.35/4.40?
