My e250 doesn’t turn on, the blue light from the wheel stays on all the time. It does not connect to the computer, and I’ve tried what I was told would put it into recovery mode (switch to hold, press and hold record while connecting it to computer) but it is still unrecognized. It has rockbox on it.
A v1 e200 not booting, with just the blue scroll ring lighting, is a sign of a loose memory board. Remove the rear cover, and have a look at the large black rectangular area above the battery module. You will see a small grey foam rectangle within this box. Give it a gentle press downward; hopefully, you will feel a soft click as the daughterboard snaps back into position.
Reassemble your sansa and try powering up again.
Thank you very much, it worked perfectly
