The post about resistors is in first page of this topic. I think that there is dead chip and you can use router only as a switch. Try to connect some port of router to another router and see if the second router 'see' the mac address of Tenda.
Ok..I found the story about resistors.
As I understand he only need it to get 3.3V, but he doesn't describe why he used it, which value he used!
Can anyone tell me something abot this?
Another idea: watch booting from putty and try to connect Tenda to another router/computer and see if there is difference in bootlog
Thank you for your suggestion, I will try tonight or tomorrow

Hi, I'm the owner of a TendaW311R + router that does not work. I need to tell me if you can and if you know which points tx and rx where I can connect a TTL converter and reinstate him. I attach a picture if it helps. hardware version is 2.0 and are marked dots called TP1 to TP8, probably meant tp test point. thanks in advance
One other possibility : this thing uses CFE ( at least mine used ) . Fix some ip like 192.168.1.9 in your computer, start a continuous ping to 192.168.1.1, and turn on the router with the reset button pressed.
If after about 10s ( may be more, may be less ) it stabilizes and keeps answering to ping requests, you can try accessing http://192.168.1.1 and uploading the firmware from there.
RogFanther, can you give me more information about your router (model, firmware)? Thanks for your help and patience for me and my Tenda. The router is died because I did not how to solder but now I know and do it very good. I know new things which are unprisable for me. And I am pretty sure that I can unbrick another router. I did MAX3232 and MAX232 circuits and they works and waiting for bricked routers . Thanks again my friend !
The v2.0 is Broadcom based, with the intention of avoiding all the problems the Ralink ones presented. Mine had a place for soldering a 0.1" header for the serial connection, near the flash memory. It was of the first ones to be produced, probably. His doesn´t, seems they substituted it for those test points.
I do not remember firmware version, at the time there was only one version at the homepage for the v2 series.

I found the two points, rx and tx were marked with TP1 and TP 2, I connected a USB-UART from a nokia 6030, I opened putty and I powered the router. I received the following message
