So to continue this series of blogs about resets and persistence we’re just going to take a look at the rugged PDA resets you can do with one of the most common Semi rugged PDA’s on the market right here. If you want to see a lot more FAQ’s like this or even request one form us then just come and ask us here. The Motorola ES400 is a great little semi rugged PDA and there are a few ways to reset the device, all with increasing severity. We list them all here:
To put the device to sleep, simply press the power button. This puts the device into a very low state unattended mode that is very close to being totally off in terms of power usage.
To turn off the ES400, simply press and hold the power button until you see the screen to the left. Press the “Power Off” button on the screen when and the ES400 will be totally powered down as if the battery had been taken out.
Press the power button and the 1 and 9 keys on the keypad and hold them all down at the same time. The device will soft reset itself which deals with any glitches or application running issues you might have. A soft rest doe snot not delete or reset any of the device’s settings or installed applications, think of it as rebooting your laptop. You’ll know if the device is soft rebooting because the Motorola Boot screen will have “OS-Reboot!” in tiny words near the bottom of the screen.
Motorola call this a Clean Boot and this is how you get your Rugged PDA back to factory, default settings. Motorola have 2 ways of hard rebooting their devices:
Clean Boot with Application Wipe
1. Unzip the contents of the clean and wipe ZIP file, found here: https://docs.symbol.com/downloads/405Bw65xxDBA000001.zip, to the root folder of an SD card
2. Place the SD card in the device to be upgraded
3. Place the device to be upgrade an A/C power
4. Navigate to the SD Card and invoke the program STARTUPDLDR.EXE
1. Unzip the contents of clean and wipe ZIP file to the ES400 temp folder
2. Place the device to be upgrade an A/C power
3. Navigate to the temp folder and invoke the program STARTUPDLDR.EXE
The update will take about 1 minute to complete. Please do not remove the device from A/C power during this time.
Clean boot without application wipe
You use the exact same method as above but using a different set of files, found here: https://docs.symbol.com/downloads/405Bw65xxxCB000001.zip
If your Device is locked
lastly I wanted to add to this post what happens if the device is PIN locked or won’t go into Windows Mobile for some reason. We get devices back from loans all the time here with all kinds of software on them that lock us out of the device. This means you can’t get to the StartUPLDR file to initiate a clean. Cheers to Thomas in the comments below for pointing this out to me!
What you need to do in this case you do is get the device into its boot mode. You do this by performing a soft reset, but when you see the boot load screen you must quickly press the power button and camera button together. It takes a few times sometimes to get the timing right. This will then force the device to look for the SD card and it will clean it down to an out of box state.
