Dual Boot on the International Galaxy Note
Dual booting has always been a mixed bag. On some devices it’s deceptively easy to get a second ROM booting. In some cases, it’s even possible to boot more than two. On others, it’s a process that can take hours and can be wrought with problems if the process is not handled properly. In any case, dual booting is a fun experience and can even be practical. Now, users can dual boot on the International Samsung Galaxy Note.
The method was developed by XDA Forum Member chuandinh and includes a few different pieces. Users will have to flash a number of scripts in recovery first and install a modified kernel. While not overly difficult, there are a lot of steps. It is not without it’s issues—CM9 and other AOSP-based ROMs are not compatible, so users will not be able to save them on their SD card. Users should also not wipe data while the kernel is installed. As chuandinh explains:
But I don’t recommend do a wipe with any ICS kernel. If you want to wipe the data, flash safe kernel like Abyss GB kernel.
Aside from that, the process is pretty straightforward as long as users keep to the instructions. Users flash the ROM they eventually want installed on their SD card. Then they flash the scripts in recovery to save that ROM to their SD card. Finally, users flash the modded kernel to enable dual booting and they can flash another primary ROM, while retaining access to the one saved on the SD card. Easy as pie.
