With telnet access have you entered "passwd" to provide a password and enable ssh?

Then with ssh enabled, log back in and try again. If it fails, try "ping www.google.com". If that fails, then you have a problem with dhcp--perhaps relating to your gateway or dns setup in /etc/config/network.

ok, have recovered my hame mpr-a2 again to almost full functionality - only web interface is missing, but this buggy luci with lua installation is too cumbersome.
Now I have ethernet, wireless and usb interfaces working, can access via telnet and it's enough for the moment. 4G usb dongle works fine and right now I'm having internet via the device.

Notes
1. I already had OpenWrt flashed some time ago when I had serial connection soldered.
2. This time I didn't have the serial connection and finally didn't need to disassemble the device.
3. MAC addresses are printed on labels on the device
4. The 4G usb dongle is configured for autoconnection and has built-in dhcp.

If it helpful to anybody, below are steps I finally followed to recover:
1. reset the device - using the small reset button (a needle or similar thing is needed). Changed IP on my PC to 192.168.1.2 and logged via telnet to the router with IP 192.168.1.1 (using ethernet interface, wifi by default is disabled after reset)
2. using vi modified the following configuration files in the /etc/config folder
- network
- wireless
- dhcp

Here are the configurations

about problems with installing luci - my opkg.conf contains:
=== /etc/opkg.conf ===
src/gz barrier_breaker http://downloads.openwrt.org/snapshots/ … ages/base/
#src/gz barrier_breaker http://downloads.openwrt.org/snapshots/ … kages/luci
#src/gz barrier_breaker http://downloads.openwrt.org/snapshots/ … s/packages
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

===

from base I tried to install the following luci dependencies:
opkg install uhttpd uhttpd-mod-ubus lua libuci-lua liblua rpcd libubus-lua  libiwinfo-lua

and the luci itself:
opkg install luci

the result was:

so far don't know how to fix it.

seems to be I have too much free time: I did a very stupid thing - updated busybox package using opkg install busybox.. One should NOT do it unless de-bricking devices is the best thing he/she wants to do.
So I've lost again my hame and had to start from the beginning.
However this time I found in internet the onekeyrecovery tool along with the original firmware file and managed to repair the router and now building openwrt from repository.
So far I don't use any serial connection - with the onekeyrecovery I don't need it.

Can you link me to the original Hame MPR-A2 firmware? I've been also looking for it for a while. All I see are A1 firmwares.

Hello Mil,
Did you get the original HAME MPR-A2 firmaware?
I did the WRT firmware update few month ago but it is too complex for me. Please let me know if you ve got solution.
