Zywall USG100-Plus, Where to find the Firmware, Restarting every 15 minutes

Ramesh_Gunasekaran · January 2022

Hello All,

In December-2021 we bought a Zywall USG100-PLUS firewall VPN router, it worked fine for 10 days, after that it started to restart on its own every 15 or 20mins, I don't know what is the issue, also thought to update the firmware, but I am not able to find the firmware for the Zywall USG100-PLUSS, please do help me to resolve this issue, thanks in advance.

Hello!

I have a problem with update my USG-100Plus from this post. When I try to update firmware from 3.30(AACV.7)ITS-WK28-r72114 to the "USG 100-PLUS 330 AACV v3.30P9 (WK48)" process stopped.

On the console displays:

[Update Filesystem]
Updating Filesystem
[/util/zld_fsextract]

and rotated slash.

At this stage (slash rotated) very long time (one week) without any others actions. I was able to interrupt it only by turning off the power, after which the device does not boot with the message on the console:

FLASH: AMD 16M

BootModule Version: V1.17 | 12/01/2011 05:20:17

I can restore the device via flashed the database only (firmware restore didn't help). After the restoration the device works normally with the all my old settings.

I tried hardware reset device before upgrade - it didn't affect. What could be the reason and how can I flash the device?
