The main difference from the old one is supporting the large size image more than 48MB.
Please see the detailed explanation of update as below.
1. Unzip the cfe_solo_2.0.zip to USB stick. (There should be /vuplus/solo/cfe_cfe_auto.bin) 2. Insert USB stick into the USB port of solo and power on the box. 3. It takes just a few secs to update. 4. If solo's front led blinks continuously, restart box. 5. To proceed with image update, you should delete the cfe_cfe_auto.bin at /vuplus/solo in USB stick once bootloader update is finished.
