I know, my iPhone 2G is viejillo, and I’m the new 3GS, but meanwhile I decided to try to see how’s my iPhone with the new firmware. In addition, there were many AppStore applications that I could not install or I stop working to update them, so I started searching with Google that it had gone to people in iPhoneHeat update and found a tutorial very simple to update. So then you translate the steps that should be given and the way I describe my impressions.
INITIAL WARNINGS:
You must have a backup of phone contents (photos, contacts, messages …) and that this process will erase
You must have iTunes 8.2 installed
Before beginning the process, reading the different steps are going to implement.
Step 1. Preparation
The first is to download files and applications are going to need during the process:
Redsn0w. The application need to patch the firmware, perform the jailbreak and unlock the phone. What you can download any of these links: Mirror1, Mirror2 or Mirror3. What I bajaréis be a compressed file, once downloaded, descomprimidlo in a separate folder.
Basebands 3.9 and 4.6. These files the request redsn0w during the process. Links: 3.9, 4.6
3.0 firmware image. Here you can find it.
Step 2. Upgrade to firmware 3.0
Connect the iPhone and start iTunes. Select the device in the left pane and click the “Restore” button while pressing the SHIFT roofing / CAPS. Doing so will display a dialog to select the image file you want to use the sign the Agreement, is the last file you undertake in step 1 (a file with. Ipsw). Once selected will begin the upgrade process, it will take a while (do not worry) after which the phone will be like when did you get out of its box, waiting to be activated.
Step 3. Jailbreak, Unlock and Activation
Run the file that you downloaded RedSn0w.exe compressed in step 1. This program will launch a small wizard that will guide you through the various steps in the unlocking process.
Step 3.1 Provide the firmware image. Select the file. Ipsw already used in Step 2.
Step 3.2 unlock options. Select Unlock and Cydia (an alternative application installer, unofficial, the AppStore.
Step 3.3 Provide the files with the basebands. Select the files for 3.9 and 4.6 That basebands bajasteis you in step 1.
Step 3.4 Put the iPhone into DFU mode. By giving the button “Next>” start the prompts to start the DFU mode. My advice is that it conectéis mobile to the computer via cable directly and not with the media, as this will be easier to implement the key combination to do. If all attempts have failed to put it in DFU mode first, do not be afraid, give it a “<Back” and return to try, I went to the second and nothing happened.
Step Execution Process 3.5. There, now the software will update the firmware, patch it and unlock it, it takes a little bit, be patient it is done.
This process installs the firmware 3.0.0, but not the final version, if someone dares to make the process with firmware 3.0.1, we discuss how she’s gone.
