In the past, we have seen devices such as the HD2, Desire HD, Nook Color, Xperia Play, Motorola Defy, Droid RAZR, Iconia A500, Galaxy Note, Optimus One, Evo 3D, Galaxy Tab 2 7.0 and a few others getting dual-boot support. Today, the Huawei Ideos S7 tablet joins the club, thanks to a dual-boot kernel that allows you to install two Android ROMs on the device.
This dual-boot kernel for the S7 was developed by XDA Forum Member hal_2000 with the help of XDA Senior Member irfanbagus, who brought dual-boot support to the Galaxy Y earlier this year. It is basically the stock 184.108.40.206-ideos Froyo kernel, with no additions other than dual-boot features. Your device must have the stock kernel in order to go ahead with the process. The complete process involves installing this kernel and preparing your SD card to run the second ROM.
