Hello Endsormeans,
Sorry to trouble you again, man, but seems to me I am seeing the end of the puzzle. I reached point 3/ of your last instructions, but dont know where to start this xterm, ans where exactly to tyope these magic words "sudo gainroot..."even following the other link you gave me. Please help a again

after you have installed "rootsh" from the app manager. simply look at your installed apps on your n800 ...you know...like when you normally go to open and use any old program or game that you have installed...you know the 4 little boxes on the left there? ..
....just leaf through your installed programs and you should see one called "xterm" or "x terminal" (otherwise known by many as rootsh or root or gainroot) it's a black square icon with a $ sign in it ... tap it...and it will start up....
It should be default auto-installed by the app manager straight into the sub-menu "Utilities" accessed from your on-screen side bar menu buttons...and it should be right in there.

How ya doin' ?
Figure out where I'm talking about yet?

Hi EorM,
I am fine but still fighting until making my N800 friendlier to me - I put all thos files in dt new folder to my Removable Mem card, then open this Xterm, wrote > sudo gainroot .. and waited it to finish its work... Instead it was writtem - Enable RD mode to gain root privileges ..
Please let me know what is this RD meaning, and how to proceed
Hope you are not yet enough fed up with me, thanks and
best, velokin

you don't do r+d mode ...once you open xterm...type "sudo gainroot"....
you have only just begun! ....when I said "wait for it to finish it's work..."
I meant ALONG the process you must do putting diablo turbo on....be patient with the response time from your n800. THAT is what I meant.
So to recap where you are at... :
1- you enabled the disabled extras repo in the app manager repo. CHECK
2- you installed "root priveleges" ie- X Terminal . CHECK
3- you installed ASUI and CSSU you followed their specific instructions and both are enabled and CSSU has been installed properly and has updated your n800 to the latest CSSU. (hopefully you have done this) CHECK and CHECK
4- Downloaded the Diablo Turbo files and simply placed them in a folder on the external card in a folder simply labeled "dt" . CHECK

You are now ready to begin (congrats man! you made it this far! Still got a bit of work yet to do) .
5- Start x terminal.... type sudo gainroot. refer to the exact instructions 3/4 of the way down the post where it says "HOW TO INSTALL" here =

in xterm at this point ....after having typed "sudo gainroot"
follow the instructions stated. typing what you see after the ">" symbol EXACTLY everything there is there..at the end of each line of text and before the next ">" hit ENTER. Doesn't get simpler man.
Follow the instructions...ONLY type what is supposed to be typed...stuff in brackets is help reference...etc.

You are doin' good man!
And it is no bother ... really.
keep me posted.
