How to – Retrieve ‘Phone Lock Password’ of your N900
It happens many a times that you forget your phones’ lock code or password. Sometimes you don’t know what the previous owner had set the password to. And the only option you are left with is going to a service center. Well, if it’s N900, you may not have to. Here’s how to retrieve phone lock code of your N900 –
1. First of all, you’ll need to get Root access of your N900. To do this, just run the built-in Application Manager and install an application called “rootsh”. Then go to the Terminal Shell (use the built-in X-Terminal app) and type
2. In the same shell, type
# echo root:$(grep -A 13 lock_code /dev/mtd1| tail -1): > /home/user/MyDocs/phone_lock_hash
This will create a file ”phone_lock_hash”. You’ll find it in the path home/user/MyDocs.
3. Great work. Now, download & Install the app ”John The Ripper”.
4. Transfer the ”phone_lock_hash” file from your N900 to your PC, where ‘John the Ripper’ is installed.
5. Now, go into a Terminal Shell (using X-Terminal or a similar app) and type
$ john -i:digits phone_lock_hash
You’re done! Depending on the length of the code, it may take from a few seconds to some hours.
