Redsn0w Updated to 0.9.11b1

It’s here folks Redsn0w 0.9.11b1 is finally here. This version of Redsn0w will allow you to downgrade your A5 devices! :D So all you who have by mistake updated to iOS 5.1 will now be able to downgrade back to iOS 5.0.1 ONLY IF YOU HAVE YOUR SHSH BLOBS.

Here are some important points you need to note before attempting the tutorial below on how to downgrade your device:

  1. You cannot downgrade without the personalized SHSH blobs for your device at that lower firmware. You need to have fetched those blobs while the signing window was open, using either Cydia’s built-in TSS@Home feature, or with TinyUmbrella.  The new Restore screen of redsn0w lets you choose either the remote blobs or local ones (for the earlier firmware). If you don’t know where TinyUmbrella put your blobs, TinyUmbrella has a button that will show you (copy them out of that folder and feed them to redsn0w).
  2. The A5 downgrade method actually updates to the latest firmware before downgrading to the earlier one.This process updates your baseband to whatever is newest.DO NOT USE THIS METHOD IF YOU RELY ON UNOFFICIAL UNLOCKS of your iPhone4S.  Those who used the temporary SAM technique to unlock their iPhones to specific SIMs shouldn’t be affected by this baseband update.
  3. This method can be fixed by Apple with a firmware update.
  4. This update involves a bunch of new redsn0w code and so The Dev Team recommends sticking to the previous version 0.9.10b8b unless you’re specifically using this new feature, until all the bugs are worked out!

So here is how to downgrade your A5 device:

  1. Download Redsn0w 0.9.11b1 from our Downloads page.
  2. Fetch your blobs via Redsn0w or TinyUmbrella.
  3. Download the 5.0.1/5.1/5.1.1 firmware from our Download page.
  4. Put your device in DFU mode.
  5. Open Redsn0w > extras > Restore
  6. Now select the 5.0.1 firmware.
  7. Now choose the IPSW for the firmware you are on.
  8. You have to now choose whether to use “local” or “remote”.
  9. Now it will start downgrading your device.
  10. If you have done all the above steps correctly you should be able to downgrade your device.

And thats pretty much it folks! That is how easy it is to Downgrade your device.

Note: If you are getting any error in iTunes while downgrading you can check our iTunes help page.
