Guidance Through iPhone Problem

[BuStOsAvIcH]

So here's the situation that I am currently in:

iPhone 3GS
Old Bootrom


I was on 3.1.3 JB using PwnageTool. I made the decision today to upgrade via a Custom Firmware to 4.0. The process hung for over 2 hours so I decided to restore. I have all my SHSH blobs on file since 3.1.2 on Cydia and on TinyUmbrella. Unfortunately, they wouldn't restore to custom firmwares on any of these OS's so I had to upgrade to official 4.0.2 to get the phone working. I am able to downgrade to the 4.0 official firmwares. How would I go about getting the Custom 4.0 Firmware installed on my iPhone now.

Feel free to ask any questions about my situation.

Thanks in advance for your help.

You have your SHSHs backed up all the way to 3.1.2? Then nothing you do will take you off the jailbreak train.

Restore to vanilla 4.0.1 using iTunes and jailbreak with jailbreakme.com.

Make sure you install the PDF patch when you're done.

Wouldn't upgrading to 4.0.2 permanently stop me from using JailBreakMe.Com?

Yes, but the general advised 4.0.1, not 4.0.2

I thought it might be a permanent patch if I ever upgraded to 4.0.2 but I just tried it and it worked. Thanks for your help.

Only 4.0.2 patches the jailbreakme.com exploit. You should be able to upgrade to 4.0.1 w/ SHSH.

If you upgrade to 4.0.2, no sweat, you can just downgrade to 3.1.2 because you have your SHSH backed up.

Does this mean I can not use PwnageTool to install a custom FW to the next OS whenever that comes out.

No, like I said in my first post, you will always be on the jailbreak train because you have your SHSH for 3.1.2 backed up, which means you are able to downgrade to 3.1.2 and jailbreak with redsn0w, which is your ticket back onto the jailbreak train.

Obviously before doing anything, you should double and triple check and make sure your SHSH for 3.1.2 is backed up. It should say at the top of Cydia.
