Bad Blocks after firmware upgrading

[KevinBKK]

I've just done the firmware upgrading of my falcon 128 gb to 1916 to enable the trim command. While the firmware upgrading software is doing its tasks, it said something like bad blocks scanning and then it listed the blocks that I believe they are bad blocks. So my question is
1. Are those blocks considered the bad blocks?
2. if so, anyway to repair them, or I can run back to store to get a replacement if it's still under warranty?

Thanks so much

Hi KevinBKK

you can use FW-1916 clean tool.
it can solve this problem.
you don't need RMA.
