Boot Loader Recovery Nov 19 2020 If you originally had V2.4.8 and you previously upgraded to V3.2.2 or earlier, it may have created a problem where you can no longer update the firmware to any version.

You can solve this issue by loading the bootloader recovery file, then loading the latest firmware.

Caution: Do not load the Boot Loader Recovery file unless you have V3.2.2 or earlier AND you are unable to load new firmware to the unit. Using this file indiscriminately can brick your unit.

If you have V2.4.8 or if you have a V3.2.2 or earlier which lets you upgrade, you can update to V3.2.3 directly. Best to try to upgrade directly first, before using the Boot Loader Recovery.

2.4.8 Sept 01 2016 Original Stable Release
