peterleinchen,

The "flasher trick" is not a trick but just using flasher to charge the phone to around 10% before plugging it into a wall charger to continue charging... since a flash doesnt occur before the battery is at 11%, flasher charges it to that level...

Regarding the alarms, maybe death_jax is referring to unrestricted sys-ui as its known to cause the same issue on non-ubiboot phones too. However although the symptoms are the same here, your case seems to be caused by ubiboot while his problem is a common unrestricted sys-ui issue...
