Setting UP Windows

1. Download Tunnelier, WINSCP, or PUTTY. In this guide we will be using Tunnelier.

  Download Tunnelier Here

2. In order to connect via SSH you must have a Wi-Fi connection setup. Turn on your phone and your phone's Wi-Fi by going to Settings, Wi-Fi, and connect to your networks Wi-Fi connection.

3. In this example will connect to linksys. Once connected you will have the Wi-Fi icon in the status bar at the top. Click on the blue > icon to show details about the connection. Write down or remember the "IP Address". In this example mine is 192.168.1.103, yours might be similar.

4. Install Tunnelier and launch it. Setup your settings similar to this, remember to use your "IP Address" and not mine, this was just an example. See screen shoot. Username: root Password: alpine

Manually Updating PRL

1. Using the explorer window in Tunnelier browse to "/System/Library/Carrier Bundles/iPhone/Zeppelin_US.bundle".

  File Contents / Size
  310VZW.dmu      260bytes
  310VZW.pri      ***bytes
  310VZW.prl      ***bytes
  carrier.plist   ***bytes
  ERI.plist       ***bytes
  info.plist      ***bytes

2. Backup all the files to your HDD and make another backup of them. This is so you don't have to restore the phone in case something goes wrong.

3. To manually update the PRL to your new carrier's PRL. Get or obtain your carriers PRL from google. In this example I will be using the Cricket_42500.prl

4. Rename your PRL to 310VZW.prl and upload it to "/System/Library/Carrier Bundles/iPhone/Zeppelin_US.bundle" making sure to overwrite the original 310VZW.prl

5. Open carrier.plist in a pList editor. For Windows I use "pList Editor" Look for "PRL Push Flag" and enable "True".

  Normally
  <key>PrlPushFlag</key>
  <false/>

  Switch to True
  <key>PrlPushFlag</key>
  <true/>

6. Save the newly edited "carrier.plist" MAKE SURE NOT TO CHANGE ANYTHING ELSE. You will break the sign if you do. After you save upload and overwrite the old "carrier.plist" found in "/System/Library/Carrier Bundles/iPhone/Zeppelin_US.bundle". Reboot your phone.

7. Once the phone completes rebooting you "WILL NOT" have service. Thats normal. You will now need to "SSH" back into the phone and edit the "carrier.plist" boolean to say "false" like it originally was.

8. After you have uploaded the new "carrier.plist" with the boolean as "false" this time. Reboot the phone again.

9. Once your phone powers on check the PRL version by dailing *#5005*4357#, send. Your carriers new PRL should now be installed.
