I have a Clarion car radio running WinCE 6.0 (pure, no Chinese hybrid). Been toying around with it for a bit, and apparently messed it up somehow.
CE Desktop is a data protection software. It prevents people peeping your screen and getting your sensitive data. It covers most area of the screen. Dec 26, 2012 - 4 min - Uploaded by Pinoy MahiligHere's how to access WinCE Desktop, or more specifically, use a file manager to access the. Dec 29, 2010 Create Desktop icon on wince 6 to use this to run an application from flash. So add some icon to your main application exe and check it out.
Normally, the device would run Hard Disk SW_Update UpdateUtility.exe, if a USB stick (mounted at Hard Disk) is present during boot. This utility allows to replace the stuff stored in NandFlash with an image on the SD card. This is simply a zip file, so easy to mess around with. Which I did, and everytime I went too far I just reflashed an older image over it using this update mechanism. Now, the update mechanism no longer showed when the device boots with the update utility on the inserted USB stick. It still booted into CE desktop, so I figured let's go back and start from scratch.
I manually started the UpdateUtility.exe and placed back the original firmware back, update completed successfully. Rebooted the device, and it 'hangs' at the manufacturers splash screen. Their main menu never shows. The update utility is no longer invoked. The SD card with 2577 autorun.exe trick doesn't work either, I'm not entirely sure whether it ever did. This effectively means I can't do **** with the device. I know that it does not completely hang, if I insert an unknown USB device I get a WinCE style popup asking for a driver (which I can't enter, there is no keyboard ).
When I plugin a keyboard it is not asking for a driver, so I believe there's at least some form of a HID driver present, but the keyboard doesn't seem to work. Now, what are my options for unbricking this device? I've analysed the device before and all prerequisites for making activesync connections over USB are in place, except, there's no external USB client port available on the device. The circuit board contains a 4-port USB chip though, but I haven't been able to find a second (hidden) USB port yet. Do these devices typically have a USB client port used in their development process? I haven't been able to find it after several hours measuring on the board.
Also, the board appears to feature a JTAG connector, but I believe this is to be used to program a second microcontroller on the device, which handles the LCD, the external buttons and retractable screen. Came across your pretty nice compilation of methods, but it seems they are all disabled on the device Anyway, it appears there's multiple updating mechanisms on the device, using an SD card prepared for a 1-year older generation device I could flash some things with a completely different updater interface. Sadly, this updater asks no confirmation whatsoever, doesn't seem to check update contents, and has no way of verifying the correct image is written to a compatible device. Now, the 1-year older generation device was mostly compatible, except for the bluetooth module.
At least I got it unbricked, and the 'old' firmware upgrade mechanism worked once more. Problem is, for my specific radio no software update has been released, so I don't have any perfectly compatible firmware files for it. Long story short, in my trying I put on a very incompatible firmware and now the thing no longer turns on Which is really a good excuse to buy one of so that I have a sane way of flashing at least that part of the board Also I contacted the manufacturer and they immediately sent me the correct image. Guess I should have done that sooner.
