Hello everyone, I have installed CWM and just installed the latest version of the Multilang Miui rom. As a result I have 3.9.6 on System 2 at the moment and just installed 3.9.13 on System 1. Is there any way to remove the old rom from system 2? Also when I first booted from the new version I was set back to factory, but 1 more reboot and all my apps appeared again. Hence I guess all you do is flash a new OS and all the app/data is still there when installing a new rom? Still new to all of this and figuring it out along the way. As I'm used to installing an OS on a computer this is kinda different as not everything is formatted. Also as it seems I have 2 roms installed now which I can switch between by simply going into CWM and selecting the other system to boot from what is the use of True Dual Boot? Thanks in advance!
