Apparently there is a known problem with older firmware with some MP3 files having info in the ID part of the file that makes the player go crazy. So update your firmware or listen to different music :-)

"Bugs Fixed: Stability· Hanging at Refresh Database with certain ID3 tag genres."

This info from page below. Also shows you how to update to latest firmware which may fix your problem

Go ahead and do this, in case the DB is corrupted:
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/Retail/DriverDownloads.aspx

I had the "Refresh Database" problem with my C250, it just sat there after turning it on! However, the GOOD NEWS is, I corrected it! First I connected it to my PC, then FORMATTED the unit. This gave me an empty player that at least would turn on. Then I downloaded the Sansa "Updater" from the SanDisk website. After setting up the updater software, I connected the C250. It automatically checked for any new firmware, and loaded it into the player. After that I restarted the C250 and it again came up OK without any music loaded. The last thing I did was to load only 1.8 GB worth of music files. My take on the problem is that if you overload the memory, or interupt a file while loading, then the "datbase" function never gets done. I've had mine running for about a week now without problems! Hope it works for you too! <Good Luck> David

I by mistake formatted My mp4 there misssing my data

Have you tired to re-set the e260 to factory settings?

I cant really help you with the reboot problem, but youy should have never taken the backplate of, that voids the warranty so that you can't return it.
