Hello everyone,
I am quite new to the OpenWrt world, and I am trying to learn something. I've got a Seagate GoFlex Net to hack and let become a NAS. I was able to successfully installing OpenWrt 15.05.1 "Chaos Calmer" from here using serial and tftp, and everything works perfectly.
Now I am trying to update the OpenWrt version to 18, but I am experiencing some issues. I can use the "sysupgade" tool, as it is not implemented in version 15.05.1, so I am trying to flash the new OpenWrt version using the serial + tftp and following the guides here, here and here. I am able to have the new kernel + root image flashed on the device, and the system up and running! But... at each reboot I lose every configuration and data (I even have to set the root password "for the first time" after each reboot). This happens with any sysupgade or factory bin images in OpenWrt Download section I try to use.
Is there a way to flash/install newer versions of OpenWrt on the GoFlex Net, and avoid losing configuration and data at each reboot?
For analysing the situation, I installed OpenWrt 18.01 using the very same steps for installing OpenWrt 15.05.1 with UBIfs that can be found here. In the following you may find are the flash layout I've got, some errors I have at boot, the mounted volumes and disk space, etc.

Thanks for all the help, and looking forward for learning something!
