Strange behaviour of k750 after flashing

[BadBoyTC]

I think it might be something to do with the battery. You could try a different battery?

[hyperion17]

I did that (using a w600 battery) and it acts the same way. I've noticed they have the same battery :BST-36. I saw k750 uses BST-37 battery. Maybe that could be the problem?
Any other suggestions, please?

You tried to replace BST-36 to BST-37. This may fix your problem.

Nice day
