Having two separate iOS versions on your iPhone, iPad or iPad running iOS 9.3.5 is no longer impossible. Thanks to CoolBooter, you can dualboot your device in just a couple of minutes, and it is as simple as installing an application from Cydia to prepare all the things necessary for the installation for you.
Now that #iOS 9.3.5 is Jailbroken with #Phoenix #Jailbreak, your 32-Bit devices can get a second life running your favorite version of iOS, no matter if that is iOS 6.x and iOS 7.x. Coolbooter works by installing in a completely separate partition the secondary iOS version, and therefore you can have both iOS 9.3.5 Jailbroken and iOS 6 or 7 Jailbroken, or stock. You can also enable Verbose boot for the secondary version.
Switching between versions is as as simple as opening #CoolBooter and pressing "Boot". A little side-note, if you're using a stasher, you will have to remove the stasher, otherwise, CoolBooter will complain that it is not running as root.
Installing 1 iOS versions on your iPhone can be fun, but you should be careful while using CoolBooter! Always keep backups of data just in case. CoolBooter only works on 32-Bit devices. Currently, there is no support for 64-Bit devices, so no iPhone 5S or newer.
