blink18273, If the player is new and under warrenty I suggest you seek a replacement. If replacement is not an option then you can try reloading the firmware, there is a guide to this in the Knowledge Base here

Updating the firmware is quite simple however finding the right firmware is not and unless you have a backup of your original firmware you may have to try many different ones till you find one that works with your player.

If your player is not recognised by the MP3 Upgrade Tool then you will need to follow the Dead Player Recovery Guide here

Thanks, i have 2 more questions, how can i uncompress a .7z file, this extension is not recognized by the firmware upgrade tool, and the other question is, do you have a full firmware for a S1 MP3 Player, the firmware tool says that this is the device model

blink18273, You can use 7zip or winrar to extract .7z files. Re full firmware all these players are s1mp3 players but you will find a selection of full firmware here

hi again, i get my chpset numbers, do you know where i can found a firmware for a chip samsung 622 k9wag08uia ? Thanks.

blink18273, That is your memory chip number, your main chip will be smaller and possibly marked ATJ2085*.
Unfortunatly it does not help terribly much as there are still 100's of firmware for this chipset so you will just have to keep trying firmware till you find one that suits your player.

tadad1, i have the correct number of my board, is ATJ2085W, i think this is not common, do you know where can i find the firmware? Thanks.

blink18273, That is quite a common chip version, have you tried all the firmware for your screen size in the download section.

i have adoubt about the size of the screen of my player, with a ruler the measurement is 1.2, i have the 3.5.35 and 3.5.37 only for screens 1.5 and 1.8, is possible to make a firmware 3.5.35 for a 1.2 screen?
