S100 Wince firmware flash and recovery method using SDBOOT

The SDBOOT recovery is not the normal firmware upgrade for wince units, this is intended to be the procedure:

- to recover your s100 unit after a bad fw flash
- to switch back to wince an S100 unit previously converted to android(only if running firmware till 06/06/2014 or a 2.34 fw)

- to convert an S150 android  unit to wince (only if running firmware till 06/06/2014 or a 2.34 fw)

First you need a firmware for your unit, possibly the original one made just for your cxxx unit.
If you don't have the original firmware you can adapt another unit firmware using this tool: SetUpdateXML_EN_2.exe (this is the version for newer 1.x.9 serie of fw)

Simply put the exe in the same folder where you have extracted the fw files and run it; select your model and hit ok.
Anyway your fw will not be safe enought until you find the correct MCU.bin for your unit, so i recommend to use always an MCU that you know it work ok for you.

Second you need this package: SDBOOT_wince.zip and a possibly new SD card (2-4Gb).
If you don't have a new SD i suggest you to use the mini tool partitionwizard to fully erase all the partitions you could have created using sd-flasher or other tools.
Once you have a clean SD card you can format it in fat32 using the sdformatter app included in the sdboot archive and label it "SDBOOT" (this is important!):

Now use “SDBOOT.exe” to write image into SD card selecting the SDBOOT_bootimage.nb0 included in the zip and press START:

The fuse process will take just a second, when it's done you can safely remove the SD card ejecting it from Windows, remove it and reinsert it again.

At this point Windows will ask you to format the sd, do it selecting quick format fat32.

Now you have a  wince recovery card where to copy your original firmware on it; a tipical Winca\Roadnav firmware contain this files and folder structure:

-BTUpdate\

-image\

-MCU_FLASH

-Patch\

-S100PROGRAM\

-update.xml

Copy these files on the root of the SD

Be sure you have removed all usb devices you have on the unit, eject the CD, go to Bluetooth section and disconnect all the devices.

Power off the unit

Insert the SD it in the gps slot and power on the unit.

The process will start....

Here is a sample video of the update procedure:

Don't touch anything until the process ends.

At the end you'll have a window that will ask you to remove the card and the unit will reboot:

That's all for now, rememeber if you like my work to hit the donate button.
