Topic: Successful TP-MR3220 with MF190
Hi, I have successfully installed the openwrt 9-Jan-2012 r29697 (from http://downloads.openwrt.org/snapshots/trunk/ar71xx/ ), additional packages to use 3g and everything is working properly. ZTE MF190 is incompatible with the mode that original firmware using to connect, but they resolved in terms of connecting directly to the port ttyUSB4.
However I have some doubts. The first one with "sysupgrade", the router loses access SSH, so to get it back I had to use the serial port, so it seems that is not the best method to update the firmware.
The second is about making a small howto in Spanish to make installation easier or maybe make a squashfs with all the packages required to have 3G service enabled (if you only have the mobile connectivity package installation is more complicated, since we have to download and use a tftp from local network).
The third is about how to link to the Android USB connection, but I suppose this topic duty to search or comment elsewhere .
p.d.: On LuCI show "OpenWrt Firmware Attitude Adjustment (r29763) / LuCI Trunk (trunk+svn8187)" and kernel 18.104.22.168, but base-files are r29697
