Do you know you can update to iOS 10.2 even after the signing window is closed? You just need to use hacker Tihmstar’s Prometheus utility and SHSH2 blobs. However, you need a tfp0 jailbreak to use this tool. Otherwise, Prometheus wouldn’t work at all.

Today we will learn how to enable tfp0 on iOS 9 jailbreak. We will make use of cl0ver tool developed by hacker Siguza that will enable tfp0 on your iOS device.

You need tfp0 to use Prometheus upgrade/downgrade tool.

Before you begin, remember the following points –

• Some jailbreak tools already have tfp0 enabled. If you have used Pangu jailbreak for iOS 9.1 or Luca Todesco’s JailbreakMe for iOS 9.3.x, you don’t need to follow this tutorial.
• To check if your jailbreak has tfp0 enabled, use iOS kern-utils tool by Siguza.
• This process may require a few tries before it finally works. If you device keeps crashing, just repeat the process and it will definitely work.
• If you reboot your iOS 9 device after following this tutorial, tfp0 will be disabled. You would then need to complete the entire process again to enable tfp0.

Here’s a list of devices supported by cl0ver. these devices –

How to Enable tfp0 with cl0ver on supported devices

Step 1 Now we need to establish an SSH connection using Cyberduck utility. Start Cyberduck > Open Connection > SFTP.

Step 2 Go to Settings > Wi-Fi > tap “i” and note down your IP address.

Step 3 Enter the IP address of your device in Server.

• Port: 22
• Username: root
• Password: alpine (This is the default password. If you did change it, use the new one.)

Step 4 Select Connect. Select Always and then click Allow.

Step 5 You will now land on this path /private/var/root. If you are on a different path, remember it as you will need it in step 12.

Step 6 Drag cl0ver file from your desktop at this location.

Step 7 Go to /etc.

Step 8 Make a new folder called cl0ver at this destination (If your device’s offset was not present above, skip to the next section of this tutorial).

Step 9 Navigate to this folder and drag your offsets.dat file at this location.

Step 10 Select Disconnect and exit from Cyberduck FTP client.

Step 11 Turn on Airplane mode on your device.

Step 12 Open WhiteTerminal and type the following commands –

login root
alpine
cd /private/var/root (if you got a different path on step 9, type it)
chmod +x cl0ver
./cl0ver slide

Step 13 You will now get a line of code that will start with [*] Kernel slide. If you get Unhandled error: Unsupported device error, your device is not supported. Wait for the developer to release a future version of cl0ver.

Step 14 Enter this command –

./cl0ver.

Step 15 If you get a line that goes something like this – [*] Successfully installed patch, then you are all set.

You have successfully enbled tfp0 patch on your device. You can now move onto Prometheus tool to upgrade to iOS 10.2 firmware if you saved your SHSH2 blobs.

How to Enable tfp0 with cl0ver on unsupported devices

Before you begin, make sure you have successfully finished the above tutorial till step 11.

Step 1 Put your device in Airplane mode.

Step 2 Open WhiteTerminal on your iOS device and enter the following commands.

login root
alpine
cd /private/var/root (if you got a different path on step A9, type it).
chmod +x cl0ver
./cl0ver slide

Step 3 If you get this – [*] Kernel slide, you are all set. If you are getting Unhandled error: Unsupported device error, this means your device is not supported yet.

Step 4 Enter the following command –

./cl0ver dump

Step 5 cl0ver will now dump a kernel.bin file in root.

Step 6 Start Cyberduck FTP client.

Step 7 Establish SSH connection with your device as given in the above section.

Step 8 Go to this path – /private/var/root.

Step 9 Move kernel.bin present here to this location /etc/cl0ver/.

Step 10 Enter the following command in WhiteTerminal

./cl0ver

Step 11 If you get a message that says this – [*] Successfully installed patch, you are all set.

You have now successfully installed tfp0 patch on your device.
