If you can find a filebrowser somewhere in the menu I guess you also could edit the file /etc/passwd from there?
Remove the password from user root. It is the second parameter on the actual line so you should end up with: "root::0:0:....".
Other solutions exist as plugins where you can remove/change password even without knowing the existing one.
What kind of Dreambox do you have?
I presume you've read the important update from DMM: WICHTIGES Update / IMPORTANT update
dhwz from an other famous Dreambox Board has continued the Project
Is it still Open Source?
Some people have reported that newer DreamUP is not working very well with DM500. You could try an older DreamUP version like 2.18 for instance.

To backup your channels you can use different tools around. I'm not sure what's OK to talk about here but if you use your friend google you should find several possibilities. 
The running SW version I guess you can see under Info from the main menu?
You can also use LAN together with 0-modem for DreamUP.
I've seen some people reporting problems with DM500 and newer versions of DreamUP so you might try an older version if this happens.
He asked about caching which is not working on any official enigma2 release not on OE1.5 and not on OE1.6
Thanks dhwz.
So what Leatherface wrote in this thread is not correct - caching is also not working in OE1.6.....? 
please can we have latest tuxtxt with teletext caching in OE1.5 too... it's already in OE1.6 so it shouldn't be so hard to fix...
many people are asking for this...
Are you sure caching is OK in OE1.6?
I've testet an image build on opendreambox/1.6/dm800/experimental/20100621 but still no caching in tuxtxt...
Or do I need more config/setting to have this working like I'm used to for Enigma1?
