I can't get past step five. it says" Unable to recognize ISPW " what does this mean? and how do i fix it?

rachel, why not try ver 4.0? much faster and easier on the battery.

Is it true that if I currently have OS 3.0.1, I won't be able to upgrade to 3.1.2? I tried to JB and kept getting the 3194 error when I tried to restore to 3.1.2. What's the way to upgrade??? Do I have to wait until someone come up with JB 4.1 in order to upgrade my OS? Please advice. Thank you so much.

if you have never jailbroken, then now is NOT the time to jailbreak, you have to wait till 4.1 is jailbreakable.

Quick question, i am currently running a jailbroken 3gs with 3.0.1. I want to update to 3.1.2 but not 4.0.1/ I tried to do the shift click restore method, but it wouldnt take. probably because i never had this firmware installed in the first place. is there any way to install a specific firmware, without updating to the curent one and backtracking? thanks

if you have not backed up signatures for your phone, i highly doubt you could upgrade to 3.1.2/

Dear Team, i have been observing all the post in regards with jailbreak iphone 3GS but it seems that thre is something still to be explained or provide a little bit guideness as i know those who have 3GS (old botroom) are experiment some issue at the time to restore the IPSW created by the software...it seems that apple constantly refuse to update with the firmware...i am been trying to do everything according with your guideness but i can not get through to unlock or jailbreak my iphone 3GS (old botroom) I would like to ask a simple question; why it is that when you finish to create the IPSW with Redsn0w or Pwgnage tool this IPSW when you are using Itunes does not upgrade that IPSW, why is keep giving an error message? your response to his inquiry will be highly appreciated.

Ok this is frustrating....I followed step by step based on this tutorials. After I restore the firmware 3.1.2 and install the redsnow all I see is the completely black out screen nothing comes up and I cant power on/off ...NOTHING. But when I connect to the Itune it says im in the recovery mode but you cant really see it because the screen is black. Anyway, I have 3GS 16gb and if anyone experience the same please share. Thanks in advance.

The same problem , any help ?
Awn - June 30, 2010 at 12:30am
i have not experienced it, however; i could think of the following: 1) try the procedure on a different pc, with a freshly downloaded FW and redsnow, 2) try restoring 3.1.2 then balckrain it, just to see what happens 3) if all fails and you have an OLD bootrom, try OS4

I read the link that someone metioned below but i dont understand this ..how did you add this anyway ? " So, open the file C:\Windows\System32\drivers\etc\hosts (Windows) or /etc/hosts (Mac OS X) and add the following entry to the bottom of the file. gs.apple.com "
