HOW TO FIND THE LOCK CODE Once your N800 has booted and you have connected to the internet, install an application called "rootsh". (If you need help to do this, just ask.) There is an application called "X Terminal" among the built-in "Utilities". Open it and type the following line: Code: rootsh grep -A 13 lock_code /dev/mtd1 | tail -1 (You can find the "|" symbol among the upper-case items of the onscreen keyboard.) Press the "line return" symbol (sometimes called the "enter" symbol). The lock code will appear on the next line. Most probably it was set by a previous owner, before you bought the N800 on eBay. I have had that difficulty myself.
