It sounds to me, that you just flashed a wrong firmware image, while your bootloader should still be working fine. So you could just connect to the serial port (with a serial cable, which operates at 3.3V!) and run the few debricking commands in uboot. See the following wiki articles and also follow the links in there:
http://wiki.openwrt.org/toh/tp-link/tl-mr10u#serial
http://wiki.openwrt.org/toh/tp-link/tl-mr10u#debricking
To enter uboot, you probably have to type in "tpl" when it outputs something like "Autobooting in x seconds". Timing is crucial.

First off all thank you for your answer! Yes, I did flash a wrong firmware image, that was the problem! In your opinion, is it easy to debrick the device by this method? I will have to look for a serial cable if I want to try this!

The serial cable you talked about is something like this? http://pt.mouser.com/Search/ProductDeta … L-232R-3V3

If yes, it is to much expensive, for that price I would be much better to buy another device!

Hello, I still don't have the serial cable, but when I get it what kind of connexions do I need to make? I meand, will I have to solder anything? How manu connectors do I have to "connect"? From this image. http://wiki.openwrt.org/toh/tp-link/tl-mr10u#serial, I did not understand that! Thank you...

As the wiki states, you need to solder to TP1, TP2 and GND and connect it to your serial cable.

I foundthe TP1 and TP2, but where is the GND? From the image posted on wiki I didn't figure it out!

Thank You @otlabs. binary image works well. I Intentionally want to have 12.09 working on MR10U. Unfortunately I'm missing some packages. For example: kmod-usb-core kmod-usb-storage kmod-fs-ext4 block-mount.

I also tried to apply Your patch.

I modified

Seems that can be some general download issue. Could you upload patch file and modified source to somewhere?

thank You

--EDIT
patch seems to work with --whitespace=fix and changes are included

I made simple serial port mod, not to have device always open and laying around.

I used 2.5 mm stereo jack. I also cut the battery holders/guides inside top cover. Space is quite limited so You need to be precise with jack positioning.

2.5 stereo plug is not so uncommonly used for serial port. Example old Motorola phones are using it.

Wiring:
TP2 - TxD is at the tip of the plug (PC to Device)
TP1 - RxD is at the middle contact (Device to PC)
GND is the outer contact.

Please, try to download patch from http://pastebin.com/raw.php?i=vEAdKW6E (in raw format).

Please, ignore this - now I see the issue you refered before.

I am glad that you got it to work with --whitespace=fix as I do not know why extra white spaced were introduced (maybe it was a bug in git and/or quilt).

I've finally got my serial port ready to go but now I really don't know how to type the commands to erase the firmware and install the factory one! I found the commands that I need to wright, but in the terminal after selecting the connection type to serial and connect to the device I start typing the commands but in the terminal there isn't shown anything that I type! Could someone please help me with this!

Here are some photos of the adapter that I'm using and a print screen of the terminal! I don't even know if the device should be connected to the battery and turned on, but I've tried both ways and got the same result!

1) yes it should be powered on with its battery or usb cable.

2) your baud is wrong, you have to set 115200 (i see 38400 in bottom bar of that screen)

3) most used terminals are putty, teraterm

Yes, the problem was solved, thanks to the help of nebbia88! I used one serial USB to fix the issue, so if you need some help with a similar issue just say it and I'm sure that someone will help you!

I've installed OpenWrt and Luci and everything is working fine, but when i connect my 3G stick it doest't establish connection. Is any configuration missing?

Thanks for your support.

No i didn't, in the meantime the device doesn't have enough memory for this packages.
Case closed
