DNS325 Bricked!

[Adolfo Volpe]

Hi all,

I recently brick my DNS 325. I tried this firmware flashing it on vendor firmware and everything goes well. Later I reset the DNS, stopped all services and tried to reflash vendor firmware using the firmware update mask of Alt-f. The power led began flashing and never stop... One hour later, I rebooted the device but power led always flashing and was impossible to access via web interface. I have two qustions:

1) what was wrong?

2) using the serial connection how i can reflash the firmware (ALt-f or vendor)?

Thanks for support,

Adolfo

That is part of the test procedures, and it worked for me.

the bootloader is not able to start the new OS.

No idea, perhaps a bad flash.

When using the Firmware Updater, did all steps run OK?

kernel: Erasing... OK Flashing...OK Verifying...OK

rootfs: Erasing... OK Flashing...OK Verifying...OK

sqimage: Erasing... OK Flashing...OK Verifying...OK

 

As I never had a bad flash I'm not certain if the Verifying step effectively works, although I made all possible tests to simulate a bad flash...

 

2) using the serial connection how i can reflash the firmware (ALt-f or vendor)?

Most probably you can recover the box, but only after having the serial cable soldered in the box circuit box and establishing a serial connection from a computer (yes, you can use MS-Win for that)  we can be sure.

In a recent thread, "Support for D-Link 320 revB", some links were given on how to do this, and in another thread directions on how to use u-boot were also given.

If/when you decide to do it (solder the serial adapter), ask for more assistance.

Luck
