ASUS BRT-AC828 Bootloader Version v1.0.1.0
Vital system booting issue:
In some corner cases, the bootloader of BRT-AC828 will be failed to mount UBI volume occasionally and result in system boot failure. We strongly recommend you to upgrade bootloader from the old version to v1.0.1.0.

How to get bootloader version:

2. Use command "nvram get blver" to check bootloader version
3. You may find version information like BRT-AC828-01-00-00-08, it means the version is 1.0.0.8.

How to update bootloader:
1. Download ASUS Firmware Restoration utility from HelpDesk site:
https://www.asus.com/Business-Networking/BRT-AC828/HelpDesk_Download/
2. Install ASUS Firmware Restoration
3. Follow the instruction to update bootloader via rescue mode,
