Mitac Mio 168 DigiWalker and clone ROMs

On my Yakumo Delta 300 GPS, the ROM version is briefly displayed at soft reset. If I tap Start, Settings, System, Utility I can see the ROM version and Profile strings.

ROM version
168 = Mitac Mio 168, VB300GPS = Yakumo Delta 300 GPS, MD = Medion, TY = Typhoon, BM = BlueMedia.
WWE = World Wide English, FRA = France, ITA = Italy, GER = Germany, ESN = Espaņa (Spain)?, WWES = World Wide Espaņol (Spanish)? CHT = Chinese Traditional ?
D = MioMap

PAK version
Actually = Windows CE Build version. 13100 and 14053 = Windows Mobile 2003. 14132 and 14235 = Windows Mobile 2003 Second Edition.

How to analyse a ROM image
Open the image in a suitable file viewer. I use Total Commander, View.
Search for "release version" and you will find close to it also PAK version, date, weekday and time and sometimes Build version.
Take the release version string excluding any trailing "P..." and search for it and you will find the end of the ROM version string.
Search for "WinCE Image" and you will find close to it one of the Upgrade Tool version texts.
Now view the image as unicode text and search for the unicode string "SSDK". Close after it you will find the Profile string.

Compatibility

Although looking almost identical on the outside, there are two different displays inside. Either NEC or Sharp LCD. On the outside there is a small difference.
If the reset is near the headphone, then you have NEC LCD which is compatible with 'Upgrade Tool V1.1' and 'Mio168RS UT R0.5'.
If the reset is near the middle of the PDA, (main board is marked MIO168_MAIN_BD_SHARP), then you have Sharp LCD which is compatible only with 'Upgrade Tool V2.1'.

Mixing up between these two gives you a blank white screen.

Backup ROM

Fully charge the PDA battery and keep it connected to external power.
Make a backup of your current ROM using osloader-1.5.6.exe. ROM image made with XDATOOLS or OSImage does NOT work.
ftp://ftp.handhelds.org/distributions/compaq/ipaq/v0.30/osloader-1.5.6.exe
Use menu Tools, Flash, 32MB Save to files..
It saves 4MB chunks named flash_00000000.bin etc. in the root directory.
Move the chunks to PC with ActiveSync as needed for space.
Open a command prompt on the PC.
Enter this command on a single line:
copy /b flash_00000000.bin + flash_00400000.bin + flash_00800000.bin + flash_00c00000.bin + flash_01000000.bin + flash_01400000.bin + flash_01800000.bin + flash_01c00000.bin WinCeImg.bin
WinCeImg.bin should now be exactly 33554432 bytes = 32768 KB = 32 MB.
Zip WinCeImg.bin with a descriptive name and make it available for download.
Include both ROM version and the end of the release version "P..." in the filename to uniquely identify the ROM image.

Restore/Upgrade ROM by SD/MMC

Fully charge the PDA battery and keep it connected to external power.
Backup any data or programs that you want to save.
Use StorageTools for Pocket PC to format card with FAT16 (or FAT32?) file system.
Copy WinCeImg.bin to card. ROM image made with XDATOOLS or OSImage does NOT work.
Turn the hard reset switch on the back to OFF.
Press the joystick down or tilt left while turning the hard reset switch on the back to ON.
A menu like this should appear:
+---------------------------+
|     Upgrade Tool V2.1     |
|                           |
| 0=WinCE Image(USB)        |
| 1=WinCE Image(SD/MMC)     |
| 2=UBoot Image(USB)        |
| 3=UBoot Image(SD/MMC)     |
| 4=BIN   Image(USB)        |
| 5=Flash Type              |
| 6=Reboot                  |
| Choice: 0                 |
|                           |
+---------------------------+
Select WinCE Image(SD/MMC).
If you have white screen, tilt joystick down once and then press it.
Wait about 5 minutes for the upgrade to finish and display:
"WinCE SD/MMC Upgrade Flashing finished.
RomUpgrade OK. Restart Your Device".
Turn the hard reset switch on the back to OFF.
Turn the hard reset switch on the back to ON.

Restore/Upgrade ROM by USB

Can be used if ActiveSync works and you can browse the PDA file system from PC.

Find and run RomUpdate_RD_R01.


Turn the hard reset switch on the back to OFF.
Press the joystick down or left and turn the hard reset switch on the back to ON.
The Upgrade Tool menu should appear.


As the "USB" item is on the first line of the menu, you can blindly press the joystick in center to choose it.

After 20 minutes, the upgrade should be finished and you can reset the pda.

Why are there not pictures of all steps?

I have not dared to try any ROM update yet! There are plenty of disaster stories, even when seemingly all is done correctly. Read all post in this MTekk mitac mio 168 english rom image needed thread where I have collected most of this information.

Flashing Boot Loader

"if you rename the full flash to WinCEIMG.bin and copy into a FAT formatted SD-Card, then you can flash the firmware from SD-Card, and if you rename it to UBoot.bin (the same full flash file), than you can flash the boot loader from SD Card (from the boot menu)" Also untested!
