![]() ![]() Wait for redsn0w to recognize it and click ‘Next’Ĥ. Browse for the stock iOS 4.2.1 and open itģ. ( again, by doing this you will loose the ability to unlock!!!)Ģ. Restore your device with a stock iOS 4.2.1 firmware. iPod 2 – MC model tethered, older model not tethered.ġ.If you have older bootrom, you will not have tethered jailbreak. iPhone 3Gs devices – if you have newer bootrom, your jailbreak will be tethered.If your iOS device is not in the list above, you can still jailbreak it, but you will have a tethered jailbreak.If you have an iPhone3G, older iPhone3Gs, and non-MC iPod Touch 2G you are good to go.Read the text though… don’t just stare at the pretty pictures. The images used in this tutorial are from previous redsn0w tutorial, so do not be alarmed. NOTE: the process is identical on both Mac OSX and Windows, and also identical with previous redsn0w releases. If you don’t understand the process, or something might be a concern to you, just be patient and do not use this tool. It’s a pain in the ass, so really, stay away… The jailbreak isnt gone, but you will need to connect your iOS device to your Mac or PC and boot it using redsn0w. A tethered jailbreak means that everytime you need to reboot your iOS device ( because it is required by a newly installed package, or you run out of battery ), you will find yourself with a factory state iOS device. NOTE: using redsn0w 0.9.6b4 you can jailbreak iOS 4.2.1, but some devices will have a tethered jailbreak and other will have an untethered jailbreak. If you need to unlock your iPhone, don’t even think about using this tool. NOTE: using redsn0w you will upgrade your baseband therefore you won’t be able to unlock ( possibly ever ). Well yeah, but don’t get too excited, because most of iOS devices will have a tethered jailbreak. But I loved it!įor list of supported devices and more information please refer to the official Installing iDroid using Bootlace document.Today, the iPhone DevTeam released a new update to redsn0w which will jailbreak iOS 4.2.1. Some features and not supported yet, and power consumption is high. Now, I have a iPhone which can dual boot iOS 4.2.1 and Android 2.3.2. You can switch to Android using QuickBoot tab in Bootlace. Install multitouch and wireless device firmwares too. After installation is finished, click to “info” button on the top right corner. In Bootlace, go to iDroid tab and install it. There is a project which creates custom Android for iPhone. I recommend you to switch to Wi-Fi connection if you’re connected to the internet using cellular data network. Installing Android requires download of lots of data. It’s a custom boot loader for iPhone which can boot both iOS and Android. Once, your kernel is patched and your phone is rebooted, run Bootlace again. Install Bootlace to your phone using Cydia. There is a package in Cydia that handles this process. It sounds perfect! I created a custom (jailbroken) iOS 4.2.1 firmware using sn0wbreeze 2.2.1, restored it using iTunes and boom! My iPhone is now jailbroken!Īfter jailbreaking, I installed Android. I found a tool ( sn0wbreeze), that is not only able to jailbreak iOS 4.2.1, but also allow me to install custom boot loader. If I downgrade to iOS 4.0.1, I can easily jailbreak my phone over, but this method does not provide me full access that I need for installing custom bootloader. I used redsn0w several times to jailbreak, however I couldn’t manage to jailbreak even if it says “it’s done”. I thought it would be cool if I install Android on my phone, after jailbreaking it. I’ve been trying to jailbreak my iPhone (iOS 4.2.1) for few days. ![]()
