BR200 Factory reset after poweroutage.
I have a site with a BR200, FirmwareV5.10.0.5, that has factory reset itself after a power outage. The first time there was a several day outage at the site and when it came back up I noticed the net...
And then there is Step "iv"
iv/ The BR200 restarts and that loses all the config again.
This is an old thread, but there is no work around for this.
If you save the config to a file or have it on an Insight server, the results will be the same. The reason is that the BR200 will restart / reboot after it uploads the previously saved config file. After that, it comes back up with a Factory Default config.
If someone would post a picture of the PCB that highlights the NAND chip and includes the part number, we could fix it ourselves instead of throwing it away.
This appears to be caused by damaged configuration partition. You may confirm it by doing following:
1. Add a dummy VLAN, change admin password
2. Reboot device
3. If device is back to factory default state(dummy VLAN gone, password back to default) after reboot, configuration partition is running out of good NAND blocks to replace bad ones.
4. If configuration partition is confirmed to be bad, and the device is under warranty, please request RMA.
5. If device is out of warranty, and BR200 WAN port can get access to Internet in factory reset state, you may add BR200 to Insight. In case of power outage, following will happen:
i/ BR200 boot up, settings are loaded from configuration partition, checksum is wrong, factory default settings are loaded.
ii/ BR200 connects to Insight server, pull settings from cloud
iii/ Settings from cloud over writes default settings and operates as expected.
And then there is Step "iv"
iv/ The BR200 restarts and that loses all the config again.

It is too much effort to replace the bad NAND chip. Because existing NAND has a configuration partition with all bad blocks, NAND copy from current one to new one will result in partition boundary misalignment unless you know the partition table as well.
