ZYXEL NSA310S bricked...

Hi. I tried to install Debian on my ZYXEL NSA310S device and I must have done something wrong. Now the device does not work and I cannot communicate via UART. Can anyone help me? How to fix UART communication?

I tried connecting it via serial UART:
USB adapter: GND RX TX [no VCC]
NAS: GND [empty] RX TX [no VCC]

Unfortunately, there is no response in the Tera Term 5 terminal (COM port set to 115200 8N1).

Have you tried switching the RX/TX lines?

I haven't tried it, but actually changing the signals helped. I managed to upload different versions of uboot, including the original one, which is available here:

https://mega.nz/folder/MB1USRJZ#brKnz8M-Y-BdNaCejp0kzg

Unfortunately, I couldn't upload the original firmware with the original uboot. For now, I've uploaded Gargoyle 1.15, but sharing folders with a password doesn't work. Something's wrong.

Could someone help me install the original firmware?

kokosz887,

You can use the new uboot image

uboot.2017.07-tld-1.nsa310s.mtd0.kwb

from the installation thread https://forum.doozan.com/read.php?3,12381.

And can I use this u-boot file to upload the official software? Because right now I have u-boot from openWrt and Gargoyle 1.15 installed and the device works but file sharing with a password works poorly.

Stock FW is quite old and obsolete.

If you already flashed OpenWrt u-boot, you should able to run Debian on USB or HDD. No need for any other u-boot.

Here is how to install Debian (treat OpenWrt u-boot as "stock" u-boot):

Can I get some help with going back to the original software? I'd like to be able to compare systems.

I have a problem from point 12 of the .pdf instructions from MEGA. These comments do not work for me on ubuntu.

Ubuntu on a PC? You are supposed to execute this in a shell on the NAS itself.
