Hey guys,

My gf updated my iphone 4 on Verizon to the new OS 4.2.9 by accident when she sync'd it with iTunes this morning. My jailbreak on 4.2.8 is now gone :mad:

Is there any way I can restore/downgrade back to 4.2.8, and then re-jailbreak it?

I tried googling/youtubing for info, but all I read and saw was that I need to have the SHSH Blobs saved (when I had 4.2.8), which I don't.

Is there any way I can downgrade back to 4.2.8 or will I just have to wait till there is a new jailbreak for 4.2.9?

Thanks!

Try running tinyumbrella I don't think apple has stopped signing 4.2.8 yet. Do it as soon as u read this.

Like this comment to get it higher. TO jailbreak 4.2.9, create a custom ipsw from 4.2.8 using snowbreeze. then modify the host file as described in this video. Use the shift technique to select the custom sn0wbreeze ipsw. and then u should be good to go.

I have a similar problem, but I have 4.2.8 shsh blobs saved. I need to restore my iphone but every time I do I get error 1013. Anyone else getting this same crap? I am going to try to restore to 4.2.9 and then downgrade, is that a good idea? Right now my phone is unusable.
