[BUG] d-link 895 A3 and reboot with reset

I have a d-link 895 A3 and I try to install openwrt following the link here

exactly I tried

Firmware OpenWrt Install URL:


Firmware OpenWrt snapshot Install URL:

After flashing 1) from D-Link Recovery GUI (https://openwrt.org/docs/guide-user/installation/recovery_methods/d-link_recovery_gui) I tried to change the password using Luci. Even if I confirmed the new password the browser showed mw that the password was still to change. After a reboot (using Luci or the CLI through ssh) the router wento into recovery state... I went in that situation only by rebooting!!!
It has no sense, it is as the memory is cleaned after the reboot. The same situation happened with with openwrc 19...

Using the last snapshot of version 21 I got another problem: changes was not saved....

Hopefully I found

to ripristinate an usable router....

I would like to use openwrt but with this router it seems impossible...


BTW, I reboot by ssh and reboot command...
