Problems with jailbroken or unlocked iPhone
Having a jailbroken iphone for a week now, I feel like I have some advice to give.
First, it is quite easy to jailbreak it. Seriously, the guys at Winpwn have done a GREAT job. The tool itself could be a bit more polished on the corners, but it is fine. One suggestion i could give them is that not always we want to build a custom firmware for the iphone, since we may have already done that. You should be able to just select the pre-built ipsw, which would save you a lot of time.
Since we are on the subject, don’t try to put the phone in DFU mode outside winpwn. Winpwn does some stuff to the iphone on the background while it enters DFU mode, so it can accept your custom firmware. So, just doing it through iTunes won’t work. I’ve tried it to avoid building a custom firmware and it just doesn’t work.
One important tip: As of today, September, 12th, WinPwn DOES NOT WORK WITH ITUNES 8!!! You can’t jailbreak or unlock your iphone (or ipod touch, but i don’t see any reason you would want to do that) with iTunes 8 installed. If you use Windows, uninstall it, AND REMEMBER TO UNINSTALL APPLE MOBILE SUPPORT TOO!! Then, reinstall iTunes 7.7. You can upgrade to 8 after you jailbreak.
Then there’s the DFU mode. If your iphone is stuck in DFU mode, here is how to exit: Just press Home and Power off buttons on the same time and keep pressing them until the phone resets. Now THIS one has cost me a night of sleep, and I’m giving you for free 😉 .
If you have trouble getting INTO the DFU mode, just remember this: When winpwn asks you if you want to be instructed on how to get INTO there, it will just explain to you. No action is being taken yet. Only after the first countdown will the big deal happen. The instructions are simple:
First, there will be a countdown so you can prepare yourself and put one finger next to the power button and one next to the home button. Then, it will tell you to press and HOLD the power button. Do that for 5 seconds (countdown). The next step will be to hold HOME button while still holding the power button. Do that for 10 seconds (countdown). The last one is to release the power button while still holding the home button. This one will take longer (about 30 seconds) and is the last countdown. Your iphone screen should turn white and then an image should show up telling you that the iphone is ready to receive custom firmwares. Now your iphone is just like you want. When you open iTunes and it tells you that your iphone is in recovery mode, click the recover button while holding left SHIFT. Now you can choose the firmware you just built and go get some coffee.
More lessons to come.
