Zyxel NSA 325 / Restore stock firmware
November 10, 2019 02:44PM
Hello,

I am currently using OpenWrt on my NSA325 but I would like to run the stock firmware ( V4.81(AALS.1)C0 which is available from official page https://www.zyxel.com/support/SupportLandingSR.shtml?c=gb&l=en&kbid=M-01820&md=NSA325%20v2 ) to try to set Power On After Power Failure ( https://forum.doozan.com/read.php?3,92579 ). But I have no clue how to corectly reflash it.

Does someone know how to do it?

Thanks,

Tomas

Tomas,

Did you back up your mtds before installing u-boot and OpenWrt? that would be easier to restore to stock.

bodhi,

I am afraid not or I lost it. It is quite some time - first I experimented with Arch (alarm), then your Debian, then stock Debian (with my kernel to boot directly from raid) and I ended up on LEDE/OpenWrt (which seems most suitable for me as it is most lightweight and performs well).

Can I some how extract it from the stock firmware?

Sorry for creating another topic - I thought that it will be well-arranged to separate the Power on and Restoring.

Just for sure - I am not interested in this any more as I managed to solve it with current firmware.
