# Alternate way to get root access in JF ONT for newer firmwares with router specific encryption keys

*Disclaimer: - This is Only for educational purposes, No one is responsible for any type of damage. Any wrong step might brick your router. So be aware.*

1. First of all, follow [this guide](https://github.com/JFC-Group/JF-Customisation/blob/master/Instructions/Get-Any-File-From-JF-ONT-Home-Gateway.md) to get the file at `/flash/secure/key.txt` which is the encryption key of your backup config.
2. Go to your router admin page and download a backup of your router settings configuration from Administrator > Maintenance.
3. Decrypt the config (`.enc` file) using the command `openssl aes-128-cbc -d -pass file:key.txt -in input.enc -out output.txt` (Change `input.enc` and `output.txt` respectively to your requirements).
4. Open the decrypted config file.
5. Change the first line of the decrypted config file like this:

   ```
   config.userdb = {} os.execute("/usr/sbin/telnetd"); os.execute("/pfrm2.0/bin/iptables -I fwInBypass -p tcp --dport 23 -m ifgroup --ifgroup-in 0x1/0x1 -j ACCEPT"); os.execute("echo -e \"password\npassword\" | passwd root");
   ```
   
6. Ensure there is no line break in the line you just pasted. The whole content should be in a single line and the line should start with `config` otherwise this isn't gonna work.
7. Encrypt the config using the command `openssl aes-128-cbc -pass file:key.txt -in input.txt -out output.enc` (Change `input.txt` and `output.enc` respectively).
8. The output file should have the same name as your actual backed up config file in step 2.
9. Restore the new backup file in Router Admin page at Administrator > Maintenance.
10. Done! Now Telnet into the Router and use username as `root` and password as `password`.
