We’ve featured multi-boot methods for various devices in the past. If for no other reason, having multi-boot is just plain cool because it allows you to try various ROMs without having to lose your current installation.
Now thanks to XDA Recognized Developer munjeni‘s app Multi Boot Manager, you can accomplish this relatively easily on the Xperia U, SOLA, and Go. And thanks to Senior Member NoobCoder, there is now an easy guide for using munjeni’s creation. The guide, which is available in our newly created Sony Cross-Device Development Forum, shows you how to get multi-boot up and running on your own device.
Munjeni’s Multi Boot Manager app uses kexec and a compatible kernel to allow you to choose between ROMs. The guide covers how to configure Multi Boot Manager, extract the required images, partition your SD card, and how to get the ROMs ready to be loaded.
