If you have been active on r/jailbreak you may have heard of a new downgrade tool called OdysseusOTA. This tool allows you to downgrade back to iOS 6.1.6 without SHSH blobs. Can you imagine using iOS 6 once again after so many years of having the modern iOS look and feel with iOS 7 and 8? I was really impressed with what I accomplished today.

For users with an iPhone 4s or iPad 2 and wish to visit the beautiful iOS 6 one more time, this article will show you how to. Before we do that I just want to say that going back to iOS 6 was something I did enjoy a lot because of the firmware’s performance i.e battery life and the unique interface.

What’s OdysseusOTA and How Does it Work?

OdysseusOTA is a command line and only run on Mac OS X and Linux so it will be quite hard for a normal user to get it running and go through all the steps. However, I will try my best and explain everything in simple form in the tutorial below.

Besides supporting only two type of devices, this tool also requires your current device to run on iOS 7 or iOS 8 and it must be jailbroken. You can check out our jailbreak section to learn more.

How to Downgrade to iOS 6.1.3 without SHSH

Step 1: Download iOS 6.1.3 IPSW and OdysseusOTA v1.0.2

Step 2: Extract the .Zip file and bring both files to the Desktop

Step 3: Launch Terminal and enter cd ~/Desktop/odysseusOTA then hit Enter


Step 4: Now enter the following commands and hit Enter for each line.

Step 5: Open up your device and install OpenSSH from Cydia

Step 6: Let’s get back to the Terminal and type in a few more lines. Make sure to hit enter for each line provided.


Step 7: Go to Settings > WiFi > Name of your Wi-Fi and look for its IP address.

scp pwnediBSS ../kloader root@(The IP Address)

Step 8: When the device is connected, a question will popup up, just hit Yes

Step 9: Write alpine and hit enter (same for default password)

Step 10: ssh root@(IP found on your iOS device) and hit enter again. Repeat Step 9.

Step 11: Put your device into DFU mode with ./kloader pwnediBSS. On the screen, it will say “Magic happening now. (attempted!)”

Step 12: Quit the current terminal and open a new tab. One last command line.

./idevicerestore -w ./custm_downgrade.ipsw (replace with your custom firmware name)

Now that everything has completed. Just wait for the device to restore.


Surprise, your iPhone 4s or iPad 2 is now running on iOS 6.1.3 without using a single SHSH file.

    I’ve got an Ipad 2 with ios 9.3.2. I really regret that I upgraded it, since it became a useless piece of plastic. There is no jailbreak for 32-bit devices, so in order to jailbreak my device, I wanted to downgrade to a prior firmware. – To jailbreak a 32-it device, you have to downgrade; – Downgrading is only possible on a jailbroken device. I think that a lot of people face this issue. Is there any way around to either jailbreak or downgrade a 32-bit device with ios 9.3.2.?
