@eefo, From reading your other posts and threads, I would advice you to slow down somewhat, take a 'breather' so to speak and do some reading. For what is worth, I have varies version of power kernels on my N900 and had not experienced issue that forces me to reflash. Now, it does not mean the power kernel is absolute perfect; but so far so good for my use case.

By the way, what do you mean by "the worst experience ever", when you have a chance, please provide detail steps of what you did/or attempted to do. With the details, folks round here may offer you educated suggestion. Please consider this: when you go to see a doctor, do you answer doctor that 'I am sick' to every questions that he ask you. Chances are that you would not.

Good luck,
