Sandisk Sansa Clip Sport fw. older than 1.17

Hello, does anybody know, where can I find Sansa Clip Sport fw. older then version 1.17? Or can anybody upload that older fw.? With 1.17 my Clip Sport doesn’t work correctly, so I decided to try the older version, but I don’t know, where to find it. Thanks for help.

Sorry, but SanDisk has not made it separately available.

Firmware updates are supposed to be win-win for both Sandisk and consumers, but apparently, it became a huge tradeoff. I deeply regret installing FW v. 1.17 because of the many introduced limitations (2k object limit, back key misbehavior, etc). Can we just have the option of reverting to the original firmware (1.09)? I think SanDisk owes the consumers at least that.
