Unlocking an N800
 

Whilst not paying attention, I clicked 'lock device' rather than 'lock screen etc' and I now have an N800 that won't let me back in as I can't remember what lock code I set.

I have tried all of my usual codes I use for this type of thing, but none are working. I have also tried what I believe are the defaults of "00000" and "12345" - to no avail.

Any suggestions for what can I try next?

Well, thats embarrassing. Turns out I used my wifes birthday as the code - which is something I _never_ do, as birthdays are predictable.

Code safely changed to one I know I'll remember ;)

Re: Unlocking an N800
 

Thanks for reminding me about lock codes (I hadn't set mine).

Now that I have set mine, I would prefer to set a longer time to auto lock, say 1 or 2 days. Anyone know where this autolock time is stored? Perhaps I can edit the file for a longer time.

TIA,

Craig...

I think it's in gconf, like the display dim/blank timeouts. Get gconf-editor and poke around in /system/osso/dsm.

I was going to say that I'm not sure we should help anyone who comes asking how to unlock their N800. But I suppose it isn't too hard just to re-flash a stolen N800 and bypass the lock completely... right?

Re: Unlocking an N800
 

I would say most people would just reflash it if they stole it.

Re: Unlocking an N800
 

I don't think reflashing clears the lock code, does it? (I'm not reflashing mine just to check, but I think I remember it keeping it when I reflashed...)

Re: Unlocking an N800
 

Others have posted to this effect in the past.

I'm kinda glad the code is not lost upon reflash.

I bought an N800 recently. My wife liked it so much that I got her one off eBay. It came today - locked. It's in the original box with the manuals sealed, so i don't think it's stolen. I still have mine locked, so i'm trying "find" with piped greps to see if the password is in clear text.

On first boot out of the box, it had the "lock" screen. I flashed to diablo, which allowed me to boot without asking me the code. However, the code is still in there. The other posts were no help, unless the folks at Nokia moved the password information in Diablo. Any help would be, well, helpful. Thanks..

The default lock code is 1234 unless someone changed it. If someone did then you'll have to ask the original owner or search how to change the lock code (probably requires terminal usage that I'm not familar with).

Re: Unlocking an N800
 

There are instructions for recovering the code on my blog. You'll have to get root access on the tablet before you can do it though but I have tested to ensure that it recovers the lock code on my n800 with Diablo.

Re: Unlocking an N800
 

Thanks, Mysticode. I still can't get the lock code.

1. cat /dev/mtd1 > MTD1_DUMP
2. perl getlockCode.pl

results:
Lock Code: -40

anything i'm doing wrong?

Re: Unlocking an N800
 

That's interesting, it should work - as I said, I tested it on my n800 before posting to make sure it still works. You could transfer the dump file to your desktop, open it in a hex editor and seek to the offset that the passcode exists in my unit (0x41028) and look around there for something that looks like it. From what I recall, it was quite obvious once I found it. Or send me the dump and I'll take a look for you (add see if I can fix my script to locate it properly).

Re: Unlocking an N800
 

2. vim MTD1_DUMP

/lock_code
30x

done!

If you're willing to install a program, install http://powerlaunch.garage.maemo.org, then drop to Xterm and type in "powerline getdevicelockcode".

I just did it here, and it worked on my N800 with Diablo, booting from the internal MMC.

Re: Unlocking an N800
 

Thanks for that. My ebayed n800 arrived today and that helped me verify that the previous owner hadn't set the lock code to something exotic :).

Re: Unlocking an N800
 

Well, the powerline program worked, but the perl script did not. And, i even triied it on my device where the code was known. I also tried to find the code in the /dev folder using grep - nada. Now i'm miffed i cant find it on my own. Mysticode, if you want 2 dump files, let me know.
