If you have recently bought an iPhone which comes with preinstalled 3.1.2 firmware and latest baseband then you might be really happy to know that you can Jailbreak it with RedSnow 0.9 beta 3.

redsnow-0-9-beta-3

It is the beta 3 release of RedSnow (RedSn0w) tool which is still in testing phase. There might be some problems but it is in working condition. You are advised to take full backup of your iPhone before you use this tool because in case some problem occurs, you might have to restore your phone to original firmware.

The features of RedSn0w 0.9 are :

  • RedSnow 0.9 can jailbreak all iPhones and iPod Touch (except iPod Touch 3G)
  • RedSnow can jailbreak iPhone OS 3.1.2
  • RedSnow can only unlock the iPhone 2G (you have to install UltraSn0w from Cydia for iPhone 3G and 3GS)

Read Details About RedSnow at the Official RedSnow Page

Below are the steps to Jail Break your iPhone 3Gs running 3.1.2 firmware using RedSnow Tool in windows:

  1. Download RedSnow 0.9 for Windows or  (RedSnow for  Mac if you have mac)
  2. Download 3.1.2 Firmware for your iPhone and save it on a folder on desktop. Name this folder as jailbreak for ease.
  3. Ensure that you have latest version of iTunes installed on your Computer, If not sure, download and install latest version of iTunes. Connect your phone to computer, open iTunes, click the shift key on keyboard and click the restore button. Select the firmware file named “iPhone2,1_3.1.2_7D11_Restore.ipsw” from the jailbreak folder on your Desktop which you downloaded in step 2 above. This will bring your iPhone 3Gs to 3.1.2.
  4. Now Open the RedSnow tool downloaded in step 1 and run it. It will ask for the frimware file, select the firmware file named “iPhone2,1_3.1.2_7D11_Restore.ipsw” from the jailbreak folder on your Desktop which you downloaded in step 2 above. RedSnow will patch this file for your iPhone.
  5. Now you will see three options “Install Cydia” , “Custom Boot Logo” and “Custom recovery logo”. Of these three options, select the first only, to “Install Cydia” and proceed.
  6. Just follow the Instructions on the RedSnow Screen after this and it will jailbreak your iPhone. The iPhone will reboot and will be jail-broken by now. You will see a Cydia icon on your iPhone. If the Jail-break fails, start again from step 3 and follow all steps carefully.
  7. To Unlock the iPhone, open Cydia on your iPhone. Click on Manage > Add Source , click Edit button on top corner and press the Add button.
  8. Type  http://repo666.ultrasn0w.com  in the window (be careful, the letter before w in snow  is numeric zero, not alphabet O)

Alright… I usually don’t post to these things because my questions are usually already asked and answered… NOT the case today… There doesn’t seem to be much info at all on the new redsn0w, for that matter. I’ve actually become quite adept at jailbreaking… I was already jailbroken with blackra1n, but the unlock is so full of bugs that i’m trying this one…

Here’s the problem: I have followed all the instructions TO THE LETTER. Restored with the new 3.1.2 firmware, etc… ran redsnow, answered the questions properly (my 3GS is PRE tether), etc… after many tries, i managed to get my iphone into recovery mode, then redsn0w started its thing… When done patching kernel, i saw a “reboot” message for a split second, followed by a “your done, the rest of this process happens on your phone” (or some such thing) message.

Herein lies the problem: I’m staring at a blank screen. Its definitely on, just kinda dark and blank (same screen i saw while redsnow was supposedly uploading its stuff). The screen stays blank for a really REALLY long time (i’ve been at this for hours now), and when it finally reboots, no jailbreak. No Cydia (no its not on the 3rd page as some have suggested)… just not jailbroken at all…

If someone knows what i’m doing wrong, pls help!! Sorry this is so long winded…
