Setting up Comfast WR632AX

Hi, i Bought the Comfast WR632AX now.

I Could not find install instructions on the page eventually i found this.

So I uploaded the

*squashfs-sysupgrade.bin image using the stock WebUI"
  update page.

It did install but it did not load lucie (there was some redirecting going on but nothing showed up)

I evetually found out i accidentally used the Snapshot *squashfs" rather then the 25.12.3 (because it is that tha hardwarepage links to)

After putting the router into failsafe mode I was able to connect to the router via SSH.
I installed the 25.12.3 *squashfs from the commandline, ditching "existing config"

This seemed to have worked, since i could login into lucie. and everything seemed fine.

Then i clicked on "Enable radio/wifi" (the standard one which was already there)

Then i lost connection to to router.

Now i cannot connect to it in any way anymore. If i just boot it it kinda looks like its in a boot loop. Putting it in failsafe mode seemes to work (fast blinking LEDs) but i cannot connect no http no SSH..

I am able to get to this:

Recovery
--------
Power on the router while holding the Reset button until
the LED flashes 5 times.
The U-Boot Flash WebUI will be available at http://192.168.1.1/

very convenient looking interface:

yet which firmware would i upload there?

the SquashFS?
If yes which one?
The original Firmware?

I kind really want to avaid bricking the device further.
