I used a simple, time-tested battery calibration technique for getting rid of my boot loops. After flashing a new firmware, I use the T68 until it starts boot looping. Then I let the battery discharge to 0. When the device runs completely out of juice, I then charge it to 100% (not 99%). This isn't good for battery health, but it did get rid of boot loops for me.
It also takes about four or five refills before the problems went away.
Another option is to put the device into recovery mode and let the battery run out, instead of letting it boot loop.
