problem with sansa fuze .version 1?

[Clerafel]

Good afternoon.
I have a couple of questions with my sansa fuze.
I have the firmware version 01.02.26. that corresponds to the fuze stable version?.
USB connection with the Rockbox 3.6 No serves, that solution is, I connect to the computer and restart with the original firmware, this does not allow me to synchronize information.
radio signal never comes to stereo. the signal is really bad, which does not happen with my rockbox sansa C240 has 3.6 and it works very well on the radio.
JPG image viewer for errors, I have two pictures of 2048 * 1024 I can bring a photo but if the shift to the other and not close, you lose the zoom.
how stable is the 3.6 for the fuze, I love rockbox but I see many problems with rockbox, how I solved.

Thank you.

3.6 is getting rather old, try with a current build and see if your problems have been solved. USB works flawlessly in rockbox on my fuzev1.
