is my JM4 faulty? - SD card read only + unable to upgrade Firmware

I think I have ready all other posts but I am unable to write anything to my SD card. OR upgrade the Firmaware?

I have:

checked the card that it writes on my PC
the phical write enable switch on the SD card is enabled
It keeps saying SD-card is read only
the same happens with another SD card too

also.....When I try to upgrade the firmware it reboots instantaniously and the firmware is the same "DSP2.00 / MCU 1.05"

the fw.bin file is in the root of a freshly formated SD card
the card is only 1GB

thanks

Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware

The SD card needs to be formatted as FAT 16. There is an FAQ that tells you how to format the card located here http://www.joesjamblog.com

You should read through it. If you are having the type of trouble your post indicates, it sounds like the card is not formatted correctly. Give it a try and see if it works.

Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware

MicroSD w/adaptor is not supported by the JM4. I don't know if 128mb cards are supported either. I've only used 1GB Kingston cards in mine and they have worked fine.

Hello,
This information is correct - Line 6 does not support 128M cards or mini-card converters. See the following link for more information on updating the JM-4:

  Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
  
  New (SanDisk) 2Gb SD card arrived and it still does the same thing:
  
  "SD-Card is Read Only" on any command that tries to write to the card.
  
  Ive also followed the instructions to format a new SD card (with FAT16) and copy the fw.bin firmware to the card for upgrade but on executing this the JM4 reboots after just 1 second with no difference in anything. (can anyone advise how long this should take?)
  
  so can I assume that this JM4 is faulty and what are my options as I think I have no warrenty ?

    Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
    
    Well first I would try upgrrading the firmware by copying it from your computer onto the card and following the instructions for uprading the firmware. Since the card is read only, you should at least be able to do that. After you have upgraded, then I would approach the card reader problem.
    
    http://line6.com/community/docs/DOC-1338
    
    Why don't you have a warranty? Did you buy the JM4 used? See if the person you bought it from will take it back.

      Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
      
      yeah Ive tried upgrading the firmware but as above doesn't seem to accept the fw file on the SD card. any ideas? ive followed all the instructions i think.
      
      also yes bought second hand a few months ago but didnt check for the SD fault. looks like many people are having the same problem with the JM4 reading the SD card.

    Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
    
    hi kas
    
    you need pressing SAVE and scrolling down to 'firmware upgrade' for the update to get installed from the SD
    
    once this done, you need formatting the SD card in the JM4 to be able to use it
    
    get the PDF "JM4 Advanced Guide (Rev B) - English" from http://line6.com/support/manuals/ for full details
    
    hope this helps...

        Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
        
        So you formatted the card IN the JM4 and then put the fw.bin file on it and it still does not let you upgrade? Did you try to reboot the JM4 with the card in the slot to do the upgrade. What kind of card did you buy? I have been using a Kingston 1 GB card but I have a couple of Kodak 2 GB cards for my digital camera. I can try them and see if they work.
        
        Also, check out Joe's Jam Blog for tutorials

        Beyond that, maybe one of the Line6 guys can help you.

        unfortunately my JM4 will not allow me to format from within because it keeps saying "Read Only"

        Yes but can you copy the fw.bin file from your computer onto the card then put the card in the JM4, hold down the save button and let the pedal boot from the card? Make sure the fw.bin file is in the / directory and not in a sub-directory. If the card is read-only in the JM4, you should at least be able to boot from it. You can write the fw.bin file from your computer onto the card.

        Re: is my JM4 faulty? - SD card read only + unable to upgrade Firmware
        
        Sorry, should have been more clear. You have to power the pedal up while holding down the save button with the SD card inserted and the fw.bin file in the / directory of the JM4. Have you tried that yet?

        Well my friend, I have reached the end of the line as far as what I can suggest to you. It sounds like the card reader is no good.
