This is what I have told you to be careful when you become root.
"rm -rf /dev/*" tells machine to cut off itself from all devices meaning hard disks, screen, keyboard, mouse, .....

so from here what do i do? do i just upload the operating system again? or is the another way i should go? sorry i made the mistake. can you help still?

i may have been confused but from what i read on this forum on page two icelandDreams said it haty they did to make it work and penguinbait said to do this to fix it on page two so i thought i was only following their advice.

i reinstalled diablo to my device and all the memory is back to normal, and device appears to be fine. but i would like to try this again. so just a couple questions to make sure i do this right. do not install on my sd card (i know), install on the flasher (what is this jus incase i don't have the right idea) then open it from application manager using install file from was this the jest of it? my sd card is empty and the device has only its diablo on it. so from scratch.

Save the file to your Documents folder.. not on either card (internal/external) in the file manager. That will save it to your flash (assuming you are booted into flash, which you should be, and you haven't made any custom links).

Make sure you only have 1 SD card in the slot on an N800, or if going to N810 internal make sure your external is not in the device.

Then run the install from application manager pointing to the file in your Documents folder.

Been a while but I am pretty sure that's the process.

should i be saving it through the computer via usb to my tablet cause that only lets me save it to the sd card, or do i save it to the card and then move it to the document file on the device?

You can't download it directly to the tablet??

If you are using a computer then save it to SD, then move it with the file manager.. or bluetooth it over.

in the process on page one it says right click on the file and save as, since i couldn't right click with a stylus i assumed, lol.

Nono.. load the page in the tablet and just click and hold on the link.

Holding the stylus down simulates a right click in the tablets environment..

i love learning more on this tablet i sit there all day just search information to do more on it when i'm not at work. so i did exactly that held down the stylus placed it into the documents, and everything seems ok, memory says the device has 100MB and the 2GB SD card has only 60MB left, so hopefully that sounds right. i don't really mind reinstalling what files i want, many of them i install to learn more about them anyways. thank you for your help. it really became much easier after you explained it for me.
