it's simple if you had windows XP , go to redsn0ow proprieties and chek compatibility with windows 2000 start your redsn0w and create your no BB file easily and without problem tested by me tornaditoo

This process will not jailbreak/unlock your device. It simply gets you into a safe position to do so. After you have compleated this process, simply go back to redsnow and hit jailbreak. I skipped the 'Select IPSW' step because i wanted to have nothing to do with the stock firmware, and redsnow detected the FW automatically. From here, go to Cydia and enter the ultrasn0w repo and download ultrasn0w 1.2.5 I followed these step and am now on 5.0.1 BB 5.13.04 with T-Mobile USA

(iPhone 4) got an error code 10 when i got to the steps where i have to restore in iTunes. What does code 10 means? I am stock in the DFU mode with the iTunes logo and the USB. What should i do? Seems like i will be losing my baseband. Currently on 01.59.00. Please help.

install ultrasn0w in cydia. type it in cydia search field.

I assume we can use this method with the latest redsn0w to upgrade to 5.0.1, maintain baseband for unlock, and be able to have an untethered jailbreak?
James RIntamaki - December 29, 2011 at 1:52pm
for anyone else who had this same question, one does indeed follow this guide to upgrade to 5.0.1 while preserving baseband (using the custom ipsw you create in this guide), and then follow the normal jailbreaking guide using the normal, non-custom ipsw when actually doing the jailbreak button.

Every time I try to do a custom restore in itunes, I get error 1602. How do I fix this??

Make sure that your host file doesn't have address for Saurik's server. Remove that entry and it should work. It worked for me

i also get error 1602. how can i remove Saurik's server and remove the entry?...

How do I solve error 2005. I've tried everything from changing the position of the USB to reinstalling iTunes. Please help.

i'm try on iphone 4 ios 5.0.1, it always pop up a window said " memory exhausted ", what is the problem?

it's a ram issue. my desktop had 3gb and i got this issue. then i tried my laptop that has 8gb and it worked fine. good luck!

I encountered the same error (Win7 64-bit, 4 GB RAM). Tried killing all non-essential processes, and then tried re-booting the computer, all to no avail. What actually worked was running in 'Windows XP (SP2)' compatibility mode, rather than Win 98/Me. Hope this helps.
