Error(-48) is somekind of hardware communication error. The easiest way to fix it will be to flash the firmware. Here's how to do it.. It will take a while(around half an hour) but its worth it and will also improve the sound clarity of your phone.

What u need :
1) Motorola Driver
2) RSD Lite or Flash&Backup 3
3) Monster Pack(Flash update for(Lseries including SLVR)

Firstly you need to backup all your files that stored on phone memory because it will delete everything in your phone when you flashing.
Start RSD Lite and let it connect to your phone. If your phone is not detected (and you are certain you have everything installed), disconnect the data cable, then shut your phone off, and manually put it into bootloader mode. You do this by pressing and holding down the "*" and "#" keys while pressing and holding down the on button until you see text display on your screen. Now connect the phone back to the data cable. Now click the button labeled "...".

This will bring up the open file dialog box. Find the file you want to use (in this case select your monster pack file) and then click the button labeled "Open".

Click the "Start" button. Now you should see various messages displayed on the screen as the program processes each code group and does various other things.

This is what the phone will display during a flash:

After it's finished and your phone has given you a confirmation tone, you can click "Close" and disconnect your phone from the cable and check out your changes.
If you should get a message like this where the program seems to hang:

Don't panic. Just close the program, chance are your phone is just fine. Sometimes this happens. This is usually caused by a checksum error. There could be more serious cases where you phone appears dead. In this case try to reflash your file again. You could also try reflashing another file.

Flashing L7


Could be that the file you were trying to flash was corrupt and ended up screwing up your firmware. Unfortunatley, I have no other advice than to take it to a service center for repairs, or installing a new board..

File format not supporting


Aki1,

You have to change the BIT RATE of the SONG.
The higher the bit rate, the clearer the sound can be.

since L7 can support only up to 192(in some songs) the best bit rate for the L7 is 128.
you need a music file converter to change the bit rate. You may download one from the net.

Error message M506


I also had this problem and thought my music players were broken. The media players displayed the songs as 00:00:00 even when the file info read that it took up space and had a song length. The music player displayed that m506 error message.

I looked through forms for an answer, and I noticed I didn't try messing with one thing: THE BATTERY.

Try taking the battery out of your phone and putting it back in. It worked for me! My music players work again!
