How to update my lyra2780a

This unit is actually produced by RCA. If you go to their website you can download Firmware, and Software to update the unit. You can also try to do a "reset". There is a very small button on the bottom, if you press this with a pen and hold it for about 3 seconds it may start working again.

Make sure it's charged. Make sure the hold/lock is not engaged. Hold in the on button for 5-7 seconds until it fully powers on.

If the file is missing, it is difficult to recover. Go to RCA's website, and try updating the firmware.

I was able to access the play list using Windows Media Player. I was trying to get the computer to recognize the player, and it wouldn't do it. I even downloaded the Lyra Personal Audio Player updater... that didn't work or recognize the player.
Try the programs that are on your computer for playing MP3's.

Is it possible you deleted system files along with other files by mistake? It's a very common problem, and it would be good to know what causes this since some people say its because the Lyra allows you to delete system files which screws the device. I heard of someone that called Thomson helpline with this problem and got his replaced, so it wouldn't hurt to try. RCA has this page on the problem: http://www.rcaaudiovideo.com/Cultures/en-US/RLDetail.html?ArticleNum=112&PC= It might help... And there's this program that is said to help with the formatting, get it here along with some instructions: http://www.techolio.com/rd2780_upgrade/ Good luck!
