**BEFORE PROCEEDING, ENSURE THAT YOU HAVE YOUR PHONE BACKED UP!**

THIS TUTORIAL ASSUMES YOU ARE ALREADY ON 3.1.2!
——-
WHAT YOU WILL NEED:

* An iPhone 3G[S] — new bootrom
* 3.1.2 already installed or 3.1.2 installed via SHSH blobs. <– Broken blackra1n’d devices will work. (Especially if Spirit messed you up!).
Payload Pwner-r3 for the 3GS.
sn0wbreeze V1.7
iBooty V1.3
* LibUSB (64-Bit users read carefully!!!)
3.1.2/4.0 3GS firmware downloaded.
——-
*NOTE : IF YOU HAVE THE SLEEP ISSUE, YOU WILL NEED TO RESTORE BACK TO 3.1.2 FIRST.*

STEP A : Installing LibUSB for iRecovery

Run this mini tool to detect your O/S + Arch. — Windows + Arch. Detector

*********
WARNING : IF LIBUSB IS NOT INSTALLED PROPERLY, YOUR USB MIGHT NO LONGER WORK!
*********
Windows XP Users download this installer — LibUSB Installer
*********
Windows Vista/7 users RUNNING 32-Bit:

* Download the installer and run it in compatibility mode for Windows XP.

*********
If you are a 64-Bit user, follow this tutorial — LibUSB 64-Bit Tut
*********

Once LibUSB is installed iRecovery should be able to function now.

STEP B : Pwning iBEC + iBoot

I : Download this easy tool here — Payload Pwner-r3 for 3GS // It will help you create the payload + iBEC.

**SAVE THE PAYLOAD + iBEC WHERE iBooty is.**

——-
STEP C : Making a Custom IPSW

I : Download sn0wbreeze V1.7 from here — sn0wbreeze V1.7

II : USE EXPERT MODE!

III : In General, Checkmark “Disable NOR Flash” <– THIS IS ESSENTIAL!!!!

IV : Build it. It will be on your Desktop.

**CUSTOM BOOT LOGOS THAT ARE MADE IN sn0wbreeze WILL NOT WORK ON NEW BOOTROMS!**

*Mac Users : PwnageTool does not have this option. I don’t think it will ever be in there. Use a Windows Virtual Machine or friends PC to create your firmware.*
——-
STEP D: iBooty Prep.

Most of you know of the utility “iBooty” that I made for Aki_nG.

It will work as long as you place all of the correct files there.

I : Download iBooty GUI here — iBooty V1.3 and Extract it.

II : Extract your Custom IPSW created by sn0wbreeze with 7-Zip or another un-archiver.

III : Grab the kernelcache and bring it into the same folder as ibooty.
Aswell as DeviceTree from the folder “Firmware\all_flash\all_flash.n88ap.production\DeviceTree.n88ap”

IV :
* Rename your Kernel 4.0-Custom to “kernel.40”
* Rename your iBEC 4.0-Custom to “ibec.40”
* Rename your DeviceTree 4.0-Custom to “devtree.40”
======
Your folder should look like this :

– iboot.payload <– Created with Payload Pwner.
– devtree.40 <– Grabbed from Custom IPSW made by sn0wbreeze.
– ibec.40 <– Created with Payload Pwner.
– irecovery.exe <– Comes with iBooty.
– readline5.dll <– Comes with iBooty.
– iBooty.exe <– Comes with iBooty.
– kernel.40 <– Grab from Custom IPSW made by sn0wbreeze.
– sn0w.img3 <– Comes with iBooty.
– wait.img3 <– Comes with iBooty.
======

STEP E: Restoring to 4.0 + Booting
——-
*MAKE SURE YOU ARE ON 3.1.2 WHEN DOING THIS*

I : Run iBooty and Select “Prepare Device for Custom Firmware”. Run the Process and if you see the image, you can proceed!

II : Now open iTunes and restore to the custom ipsw.

***WHEN DONE, YOUR DEVICE WILL GO INTO RECOVERY MODE. IT WONT BOOT.***
——-
STEP F : Booting

I : Just Re-Run iBooty and select “Boot It”. If all goes well it will boot!
——-
Enjoy!
