Well, first of all, this is my first time here so I apologize if this is not the appropriate section for this thread.

Secondly, I recently purchased a router like the one in the following picture:



The web interface is pretty much broken when it comes to the 3G settings. It does not appear to work with my Huawei E173.

I logged into it using the telnet interface but I could not seem to get it to work either. I did some research and it seems to be quite straightforward: set up a chat file and change some settings and done but the problem is that the file system is read only so there is no way to change anything.

The file system looks quite similar to a dd-wrt ( i think ). It has the etc_ro folder under /.

The device itself has an option to upgrade the firmware, but I have not found any way to backup the current firmware.

According to the web interface:
Code:

Software version: 3.5.3.0 Build 1308162321
Hardware version: EDM-WiFi V1.0


This is the set of commands that are available:

Code:
3g.sh                comgt                expr                 iptables             mdev.sh              poweroff             send_sms             udhcpc

chpasswd             echo                 insmod               lsmod                ping                 route                top
chpasswd.sh          eject                internet.sh          mdev                 ping6                sed                  touch


I checked the PCB and I could find a RX and TX solder pads. A friend of mine says he successfully revived a bricked router using his arduino.

So my questions are:

- Has anyone had any experience with this device before?
- Is there any way to backup the current firmare? By some hardware method? I have plenty of electronics stuff just in case.
- Is there any way to know if it is dd-wrt capable?

Thanks in advance ! Cool

your device its HAME MPR-A1 Chinesee OEM clone (branded also as N-Link MPR-M1, Sanoxy WR-M3GU12, Icon3G MT4214 and many others), you can try to upgrade your firmware from that devices (I think the best is http://www.media-tech.eu/products/networking/MT4214#

There is also openwrt implementation, but it doesnt work well on this device
https://github.com/Squonk42/OpenWrt-RT5350

please let me know about your opinion after upgrade your router with other firmware

I tried to upload the firmware on that page but it failed:

Code:
Not a valid firmware. Bad Magic Number: "/var/cgivvHSzw" is no valid image


Thank you very much.

So i tried and burnt the firmware on the hame website and it freakin bricked my device.

This is where I got the firware from.

Any clues on how to unbrick it?

Thanks

Somehow it now came to life after plugging in the RX and TX to a FT232RL.

The new firmware looks so much better. Still won't get to connect with my HUAWEI E173
