[Scenic]

someone can see copies of CFE - bootloader [mtd0] or maybe they have one


I am looking for the version v1.0.1.0.

unfortunately I can not update the rescue mode



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:
1. Telnet or SSH to BRT-AC828
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,
https://www.asus.com/support/faq/1000814/


If you confront the booting problem that BRT-AC828 cannot boot successfully and blinks all LEDs continually and cannot fix by press reset button, please contact ASUS for technical inquiries and support.

Yes, I know, but it does not work

I would have to copy mtd0 directly from the router via telnet


My copy CFE v 1.0.0.8. [ mtd0 ]

instruction
enable telnet service in router settings [administration page]
download the putty program
ip 192.168.1.1 port 23
conection type telnet
press open

enter your login and password
connect the FAT32 flash drive to usb
see where the memory was rewritten
mount command
enter mount
For me it has been rewritten to tmp / mnt / 4GB
remember to change on your own
tmp / mnt / 4GB is with me


then enter dd if=/dev/mtd0 of=/tmp/mnt/4GB/mtd0.bin

That's all

How have you managed to solve the problem? I have the exact same issue.
