Can't reset my Sandisk Sansa E250

is it the same process for the E250v2?

No.

e200series v2 firmware & instructions. Don’t use the UIpdater.

By the way, there is no dedicated ‘reset’ button. To reset the device, press and hold the power/menu/home button (at the 1 o’clock position relative to the scroll wheel) for approx. 20 seconds.
