Reflash the Mobile Device 133
E-EQ-MX3XRG-H MX3X Reference Guide
Reflash the Mobile Device
Note: When reflashing, LXE recommends using a Compact Flash card that is greater than
64MB. Files to be loaded on the CF card are: NK.BIN, EBOOT.NB0, XSCALE.BIT
Caution
!
Make sure the main battery has been fully charged before beginning the reflash
procedure. Depleting the backup battery during the reflash process can result in
corrupted files.
Requirement: A screwdriver (not supplied by LXE)
Preparation
• LXE recommends that installation of the CF card be performed on a clean, uncluttered,
well-lit surface. The CF card is slightly larger than a postage stamp.
• Remove the screws on the endcap and slide the endcap to the side, being very careful not to
disconnect the ribbon cables, damage the leads to the external power jack, the headphone
jack or the antenna. The antenna may be taped to the endcap so great care must be taken
when loosening the endcap.
• Carefully remove or loosen all cables to an existing CF card. Remove the CF card.
How To : Reflash using Keypress Method
1. Place the compact flash card with new image files on it in the right hand slot.
2. Double-tap My Computer, then Storage Card folder.
3. Select NK.BIN, EBOOT.NB0, XSCALE.BIT. Select Edit | Copy.
4. Tap Back Arrow. Double-tap System Folder.
5. Select Edit | Paste. When asked “Overwrite ?”, tap Yes to All.
6. When the copy process finishes, remove the CF card.
7. Select Start | Run and type Coldboot.
8. Before the splash screen appears, press and hold down the <A> key. Continue to hold it down
until the displays shows “Writing to boot flash”.
Note:
If you do not press and hold the <A> key quickly enough, the display shows
“Loading OS Image”. Remove the main battery for 2 seconds, re-insert the battery
and press the Power button. Press and hold the <A> key again.
9. The mobile device will automatically reboot after flashing the bootloader. “Loading OS
Image” is displayed on the screen and when the new OS finishes loading, all software
upgrades are complete.
10. Replace the endcap, being careful not to pinch any leads or cables. The touchscreen will need
to be re-calibrated.
Once the bootloader is loaded and the files are copied onto the internal ATA drive, you can reflash
the bootloader at any time by rebooting the MX3X, and holding down the <A> key on the keypad
before the splash screen appears. Wait until the splash screen displays “Writing new bootloader”,
and you can release the <A> key. When complete (3-5 seconds), the MX3X will reboot and
startup with the new bootloader again.
