Hello,

can I find or change my password using the created "nvram.bin" backup using a hex editor?

I forgot the password, but I have a backup file.

If so, how...example: edit the backup in hex editor and change the password to 00 00 ... or?

No, it's encrypted.

http_passwd=$1$PQG4vqWH$oA52Xl89NbuhoJPotreut0
http_username=$1$PQG4vqWH$EzOf9Gz42tHyJxklRUyZp/


Do you have SSL/Telnet access to the router?


nvram set http_username=""

The GUI will ask you to set a new usrname/password as you did the first time.

You may have to reset the router. Enable SSL or telnet.
Telnet/SSL into the router.

Restore your backup.

From the SSL prompt reset username.

Ok,
I reset the router then
login into router via telnet
restore backup via webui

When restore the settings, the router restarted and logged out automatically over the telnet.

If I want to log in again over telnet, it wants my lost password for me.

And what about this:

Using an DD-WRT startup script to reset the UI password. The DD-WRT scripts will be run when the router boots, but will not be wiped out when you restore your backup. This way, you can get onto the router, configure the script to reset your password, then restore your backup and reboot. Upon first boot, it should reset your password for you (may need another reboot).

First reset router to default
Login and setup/save startup script to reset username/passw
Load backup and restore router (after restore, router automatically reboot)

Is it possible ?

Is there any reason that you can not just apply all the settings by hand again?

The restore will wipe out those commands.

What you can do at your own risk is:

1. reset to factory defaults
2. On reboot:
Keep the username the same as what is in your bak file
change the password to something that you know
3. do a nvram backup
4. Open each file and copy the text (between the the special characters) for http_passwd"^@(text_to_copy)^L from the new bakup file to the old one
5. Upload this modified file
