BigBoss has compiled a FAQ for issues with 2.0 and 2.0.1 here.



Step 1.

Download PwnageTool 2.0.1 here, or here. If you have installed the previous version of PwnageTool then delete or rename it so there are no conflicts with this newer version.

Download the 3.9 and 4.6 bootloaders from the Internet. You'll have to find them yourself, I won't provide them.

If you haven't already downloaded 2.0 firmware from Apple, then you can download it here.



Step 2.

Prepare to lose the data on your iPhone when you upgrade to 2.0 firmware. Note: when you update to 2.0 with iTunes you will be asked if you would like to back up your personal info (network settings, call logs, email accounts, SMS chats, contacts, et. cetera). You can restore this backup after you are done with PwnageTool.

You can do this from 1.1.4 firmware (I did and everything was fine), but it might be best if you did this from a fresh restore to 2.0. When you are ready to upgrade, plug your iPhone into iTunes. You should get this pop up (if you are running iTunes version 7.7 or newer). It could take 15 minutes to install. If you are already on 2.0 firmware then proceed to the next step.

Step 3.

Launch PwnageTool. Make sure the Expert mode button in the top left corner is selected. Click the iPhone on the left.

iPhone



You should get a green check mark on the iPhone you selected. Click the blue arrow button in the lower right corner.

iPhone




PwnageTool will search for the 2.0 firmware on your computer first, then from the Internet. When it displays the firmware file, click on it, then click the blue arrow in the lower right corner.

iPhone



You will be at this screen and have many choices you can make. Click on General. Then click the blue arrow at the bottom.

iPhone



At the General Settings screen, if you are not using an authorized carrier, then check the box for Activate the phone. If it is not greyed out, then check the box for Enable baseband update. Check the box for Disable partition wipe-out. Click the blue arrow in the lower right corner.

iPhone



At the Bootneuter settings screen, check Neuter bootloader, check Unlock baseband (only if you want to unlock), then check Auto delete BootNeuter.app. Click the blue arrow in the lower right corner.

iPhone



At the Cydia settings screen, click on the Download packages tab. Then click the refresh button and you should see a list of packages. Anything you select from this list will be added into your custom firmware so you won't have to download the package later. I am only going to select the Cydia installer. Make your selections and click Add to queue.

iPhone




Click the Select packages tab, and check the box for Cydia installer or it won't be installed. click the blue arrow in the lower right corner.

iPhone



At this screen click the blue arrow in the lower right corner.

iPhone



At the Custom logos settings screen, you can choose to use the suggested images by leaving their boxes checked, or uncheck them and use the stock images. If you click on Browse... you can add your own images in their place. Click the blue arrow in the lower right corner when done.

iPhone



Here is a template image you can use. It is 320 by 480 in size. It has a one pixel, transparent border on all sides. All you have to do is paste in your 318 by 478 image onto it and center it. Then just save the image with the transparency intact and your image will work. Make sure your saved image is 100kb or less.

iPhone



Finally, click the Build button and the blue arrow in the lower right corner.

iPhone



You will receive a pop up warning if the 3.9 version bootloader is not found. Answer No to this question.

iPhone



You will then be asked if you would like to browse for the bootloader. Answer Yes.

iPhone



Now navigate to where you saved the two bootloader files from Step 1. Select the BL-39.bin file and click Open.

iPhone





You will receive a pop up warning if the 4.6 version bootloader is not found. Answer No to this question.

iPhone



You will then be asked if you would like to browse for the bootloader. Answer Yes.

iPhone



Now navigate to where you saved the two bootloader files from Step 1. Select the BL-46.bin file and click Open.

iPhone



Now name your custom firmware file and select where to save it.

iPhone



You will now see this screen while your custom .ipsw is assembled. This stage is about four minutes long.

iPhone



You will be prompted to enter your system password.

iPhone



You are then asked if your iPhone is CURRENTLY Pwned.

iPhone



Follow the on screen instructions to put the iPhone into DFU mode. At this point iTunes may launch, along with a pop up mesage, just move them out of the way at this point.

iPhone



Confirmation will appear when you are in DFU mode. Close PwnageTool.
