I've been loving my SX Mini M-Class, but it just started acting up, as the power is fluctuating all over the place. This is happening in TC mode as well as non-TC mode. At first I thought it could be a bad battery, but I've used several brand new ones (LG HE4, HE3, Purple Efest) and the problem won't go away. It's almost like the power from the chip is "fluttering" and going on and off in very short bursts. Has anybody else experienced this? I love this mod and have never had an issue with it until yesterday. *edit: I've even tried to re-flash the firmware, to no avail (running v2.2).
