"upgrading" from ios 6.1 to 6.1
Hi there. I recently jailbroke my iphone 4. I have installed a lot of tweaks, perhaps too many. My phone has slowed down and appears to be more bugg. I would like to start from scratch, and just install the tweaks I need. Which is really just "clips".
Here is the situation. My iphone is currently updated to ios 6.1. I have used a Cydia tweak to save my shsh blobs, and mailed them to myself (after the jailbreak). I have no wish to upgrade, just to restore my phone to 6.1. I have tried tinyumbrella, and I just can't make it work. I am not sure if I have understood the tutorials correctly, or if it is just not possible.
Can anyone clarify for me. Thx in advance. P
