I'm uploading this because someone could find it useful, it's not directly retailed to OpenWRT, but it happened because of OpenWRT community and great guys behind it!
If you use this FW update you AGREE to bear all responsibility if you brick your router!
This is original ( official FW update for MR3040 http://www.tp-link.com/en/support/downl … n=V1#tbl_j) just modded header and checksum to be able to update it form original Chinese Web interface of MR11U!
It will change your language form Chinese to English and it will change your router form MR11U to MR3040 , so you will be able to update ( hopefully ) with next offical MR3040 FW update for hardware v.1
I have only HARDWARE version 1 of MR11U, so I can not tell whether or not will work for MR11U HW v.2, most likely will not be able to update over web!
[s]I tested only basic ( Router mode - DHCP WAN+ WiFi WPA2) functionality so I can not confirm that all functions are working![/s]
Look -> Edit two
MR11U - default IP is: 192.168.1.1 after this FW update default IP will become: 192.168.0.1 for MR3040, user name and password are admin/admin default ones.
There is two firmware inside the archive one for updating MR11U (MR11Uv1_CH_to_MR3040v1_EN_3_12_11_up(120328)_webflash.bin) and second one Revert_Back_form_MR3040_EN_to_MR11Uv1_CH_Webupdate.bin to get back your Chinese interface if you want to go back to your MR11U original FW!
Firmware MR11U Chinese to MR3040 English Webupdate
Hack with OpenWRT!
Edit one: Updated Links
Edit two: Added the same MOD but for TL-WR703N v.1.5 Chinese - flashed to MR3020N v.1 English, ( side effect LED does not behave like in WR703, but will light on only if you connect 3G Modem! Everything else seems to work!)
Router IP address after flashing for WR703N will change it's default IP address form 192.168.1.1 to 192.168.0.254 - user-name and password are: admin/admin as default ones.
After reverting back to Chinese, the IP and WiFi name are kept, does not revert back! If you want to revert to default ones restart the router using "reset" button.
Revert_Back form Chinese to English is also included!
Tested functions On modded MR11U tested almost all functions - till now everything is working as desired like in the Chinese interface! Including tested two types of ZTE 3G modems. The only side effect till now is 3G LED flashing in '2S period' without 3G modem connected, with modem connected 3G LED light as designed.
Probably flashing original MR3040 v.1 and MR3020 v.1 (with Revert_Back...bin) will do the same - change the WEB administration interface - language form English to Chinese, but I have no these so I can not confirm that it will work!
I'll probably not use this ORIGINAL TP-Link firmwares because they lack many functions that I desire, also both my MR11U and WR703N are modded with 8M Flash and 64MB RAM, so with original firmware I can not make use of this upgrades! But with OpenWRT I can !
Edit three: Updated firmware links
