BR500 reset to factory defaults after power outage

---

MrJoshW wrote:

In earlier firmware versions of the BR500 when device is connected to Insight over some time, the NAND flash which stores the configuration can become corrupted due to long use of writing to the NAND flash. This was addressed in a later BR500 firmware release. However, due to the corruption of the NAND flash when the unit reboots configurations will be wiped in the process as it cannot read from the NAND flash. Please note however that if the device is still being used by Insight this is not an issue as the configurations are stored in the cloud and any reboot that takes place the configuration will be re-stored from Insight.

 

Due to this issue, we recommend correcting the NAND flash and this can be done by support through the Secure Diagnostics Mode access.

Thanks for explaination ,

If I haven't use Insight at this days , There will be no problem when the router reboot ?

If I leave the "NAND Flash" without correcting it , This can cause any future damage ?

Could you explain how Could I Correct it via my side ? ( Have a guide with picture or Video  ? )

Thanks.

I'm the OP. I'm glad a full explantion is now out there. Indeed, i had a tech go in the "backdoor" and fixed the issue. I had the newer firmware already, but the flash was corrupt, causing the issue. The good news, I had copies of my config files and was quickly able to restore. 

Moral of the story: If you make changes, backup your configuration files!

If the NAND is already corrupted not being on Insight any longer would not change this. We do not allow customer access to the internals of the sytem and this can only be done by a tech support representative.

How could check from my side if the NAND is corrupted ?

BTW , If I have another BR500 that not connected any time to insight , this will not corrupte the NAND? the problem accure when the device try conntact with insight cloud for the first time ?

Thanks .

Hello,

Checking the NAND cannot be done by a customer, it can only be done with a support agent checking the BR500 through secure diagnostics mode.

And yes, if the device has not been boarded with Insight and was not on a previous firmware that had the existing issue the NAND should not be corrupt.

Which Version Firmware Number was caused the problem to NAND ? 

Thanks.

Hello,

Issue was fixed in later firmware versions. Versions 5.6 and back would still have the issue if the device is on that firmware.

One issue. I was already on the latest Firmware when this happened. I keep the Firmware up to date at all times.

Thanks,

IF you have this version and you didn't register to Insight , This mean the product is fine and no harm will casue to NAND , right?

Also , The NAND Corrupt will influence only on the configuration settings reset during a power down or this will influence about the performance of the BR500 at general and on speed and so on ?

Thanks again .

This is still cause to you at last version ?
When this Happen to you first which version you had ?

Thanks

No, the issue should not happen on the latest version as it was patched. However, we can only verify if the NAND is corrupted by enabling the SDM mode on the BR500.

Once you have enabled this, please feel free to send me a private message with the port number and I can verify for you.

How could I enable SDM Mode on BR500 ? Could you explain me please?

There has command that I can run to check the NAND ( I understand on networking and programming ) 

Thanks.
