Going back to original version

[knfevg]

I just used the procedure described in the Wiki for dumping the ROM of my Tytn.
I now have 3 RAW files. I've also copied the Ext_Rom to my local hardisk so I have a back of it too.
The question is whather this DUMP has the Radio ROM too or only the PDA. What about the SPL and IPL and Radio-bootloader?

If I know use the Unlocking program and upgrade to a different ROM, will I be able to get back to the EXACT situation I have now?
I'm asking because my device was purchased from Orange Israel. If anytime in the future I'll need their support, I better have their original ROM installed. Will I be able to revert?

I have this same thing, only I've already installed Black 2.5, but I do have the .raw files and the ext_rom, but I do not know how to reconstruct :(

(this should work on hermes)

I just can't figure out how to create a OS.nb file :\

I just downloaded one of the WM5 WWE roms listed on the wiki and extracted the OS.nb from it. After a bit of trial and error i have managed to load back the original dumped rom that i created before i loaded Black 2, just need to work on replacing the splash screens, as those didn't return to original

From what i can tell this has only restored the OS, Radio Rom and everything else are unchanged
