    Default Device not recognising SD Card

    Hi all.

    Basic question that i hope someone can help me with.

    Device working well! however flash image is horrid. I've been trying the 'usual' method of trying to change image using sd card. However, after some experimenting, I am not convinced the device is looking at the SD card on startup.

    I've tried placing a txt file named 'FGo2CE.bld' with some text contained within it. Makes no change and device just boots as normal.

    So can someone advise on what the 'logoXXX.bmp image name should be for this device or how to confirm that the device does indeed check the SD card on boot up.

    ROM version V.912C.211100.120222.128M

    Thanks

    Hi!
    I have a problem with my 5' GPS navigator: (563BMSB4FSG1108062)
    WinCE 6.0 -Mstar ARM9-MSB2521-(480x272)
    data from System Information:
    Ver:700CB800-C01251108021-110811000P4M1000000010081700
    Ram:93.92/128.00MB
    Flash:7.69/256.00MB
    because the Pc antivirus software delete the Nand flash.
    After that I was update the wrong firmware (Restore WinCE 5).
    Please help me and thank you in advance.

    Small update. The SD card reader is working as normal once device is operating. I can access WINCE 6 (via userface icon). I am using a micro SD<2GB (not HC) formatted to FAT with the logo image located at root. I'm suspecting that the device is somehow locked to prevent updates etc yet i can freely access WINCE!?!. Can anyone advise on how to test this theory? I'm really content with the device once i get that splash image changed (device fitted into car dash).

    Ok, i decided that i had little choice but to try reinstalling the firmware. I fortunately found the firmware download which matches my original firmware to withing the last 3 digits of the firmware number. I guessed worth a try!

    Fortunately this worked. Blue screen on startup, new image loaded and the firmware updated.

    I wa then able to edit the logo.bmp file and repeat the firmware flash -so success new image loaded.

    Now last bit! I'd like to remove nearly all the icons on the home screen. I have no need for the calculator, unit converter etc.

    I've tried using ceregedit to review the registry/config and of course switch off many of the icons (set to 0 instead of ). However. Some of the icons refuse to turn off -even with the ceregedit showing them as set to 0. Namely the calcualtor and unit converter.

    I guess something else must dictate their presence on the home screen.

    Any ideas?

    Always first of all ask seller/manufacturer for help. They are the only ones who can tell you correct firmware(ROM)-version applicable to your device. All what currently can be said is that it's a GPS based on a "MediaTek" (MTK) board. Inbetween you also can do a Google-search narrowed down to "MTK YG-84A-V1" ...

    anyway i can check the firmware since i can't see it from the screen? Pls advice...thanks.

    update,

    when i power on, i will see the screen as below...but i do believe that the software are intact as i can 'fire' up my gps software when i randomly touch the screen as i can hear the gps sound like ' searching for satellite'

    The only problem now is i cannot see anything, thus anyway to resolve this issue? Any help will be great. thank you.


    and how i brick it was that i actually copy two files into the sd card. It was a 24bit logo.bmp and a 912c.img. The problem is that this img file was actually a bmp file that i rename it to img extension. which i believe that i have corrupted the original img file?

    Hope anyone with the infor can help. Thank you

    Just a random guess, but maybe the bitmap you used was the wrong resolution?
    You could try putting in the root of the sdcard a logo.bmp and a 912c.img for a different resolution and see if that's enough.
    From the pictures it seems the screen resolution is 800x480, but it could be 480x272 instead.

    Maybe the .img was recognised as a firmware update, corupting the system?

    File 912C.IMG is used by Update.exe if you re-flash device. File 912C.IMG is NOT the boot-logo file, this always is named at MTK units logo.bmp. Bitmap's file size must not exceed 2MB, color depth must be 24bpp

    Do a Google-search for YG-912C-W6-ABFSJ-1M-1D-AS-6LS: Probably you will find link to correct firmware at a russian site.
