So...

After I read all of this thread....
I still don'tt know what would be the better thing to do,

I run N800 under chinook 2.2007.53-3

I was thinking to format it all new, by using the usb cable connected to the windows pc and uploading one of the ARM.bin from the tablets-dev.nokia.com

The only thing I couldn't figure out... will it better to install this old chinook version again, or to take the new diablo 5.2008..43-7

I need a stable system without any memory leakage, fast battery drainage or any other "surprise"

Please write your advice

Thankyou
Tori
