In this topic we will introduce how to backup and save SHSH to Cydia using Redsn0w for Mac. For who don't know, Redsn0w 0.9.9b1 won't ask you to choose ipsw file when you jailbreak your iPhone, iPod or iPad as it will automatically detect the best solution for you (tethered or untethered jailbreak).
Let's see how to Save iPad SHSH Blobs using Redsn0w :
Step one :
Create a folder on your desktop and rename it with Pwnage , then Download RedSn0w 0.9.9b1 from here and place it in the Pwnage folder then Extract the RedSn0w.zip file into the same folder.
Step two :
Run Redsn0w application from the folder we just extracted.
Step three :
When RedSn0w opens click Extras button.
Step four :
Click SHSH blobs button from the Extras menu.
Step five :
Click the Fetch button to fetch the SHSH blobs on your device and send them to the server of Cydia.
Step six :
Conect your iPad to the computer while your iPad is OFF then click the Next button
Step seven :
Now you will be guided by Redsn0w through the steps to get into DFU mode.
Step eight :
Your iPad will restart now.
Step nine :
RedSn0w will then begin fetch the SHSH blobs from your device and submit them to Cydia.
Step ten :
When your submission is completed you will be notified. Click the Back button to return to RedSn0w.
Step Eleven :
Click the SHSH blobs button then click the Query button to make sure Cydia has your blobs saved.
Write * into the ECID text field and click OK to check all devices

RedSn0w also saves your blobs in a plist located within the RedSn0w folder. We would recommend keeping these for added safety.
