I want to have in one partition stable version 14.0 (Singapore) and the other the current multi version (now 4.6.13) with true dual boot. Problem is that when I flash a new version in one partition, and I try to reboot in the other one, after some time, the phone gets into a boot loop. The only solution is to reflash the other partition - without wipe. Any idea why, and what do I do wrong. Or is this a bug somewhere ?
