I already tried asus restoration mode, can't get it to work again.
I think i really messed up the things, because when i power on the router all the leds except for wireless and wps stays allways on, but!!!, with like 25% of max brightness. I wope u can understand what im saying.
I think i need to know the jtag points and some tuto to build my own usb jtag bridge if possible. Otherwise, i can live with a pararell or serial bridge.
PLease help me, i will be very appreciated.
If nothing can be done, can i send the router to someone to help me getting this to work?
Thank you all
PS: the router that im talking, is a RT-N10 H/W Rev.D1.
It have a Broadcom 5356 chip. an etrontech chip(i think its ram) and a winbond flash chip)
Later today or tomorrow i can add some high rez pictures of the router chips itself. |

PIN_HEADER J4

if anyone have this router and have some h/w capable to know wich is tx and rx, pls let me know.
After this, can someone point me to some tutorial or something that can guide me to build some serial flash tool, to flash the CFE. I need this, because, already stated, i think i messed up the cfe. |

thanks for the reply. Has you might notice, i've stated that the leds of the router, now only have like 25% of their inicial brightness(when the router was fully functional). Because of this, i think i messed with cfe.
I tried to flash ddwrt, it was succesfull. After that, tried to access webgui and broadcom cfe appears. In this menu, i've hited erase nvram, and after reboot. After this, the router started with a reboot loop, dont know why. I've made a cold boot restard and bang! never booted again, and the leds started to emite less brighteness than before. |

| | Posted: Sun Mar 17, 2013 17:38 Post subject: | btw, im trying to get a lan connection with it, without any success. PC does not see the router, and the Lan connection is always off. tried to ping the router without any success too.
So let's buy that adapter and see what can i do.
I'll keep you informed, because i will probably need some help to achieve this.
Thank you all again |

have one of those chip

http://www.datasheetdir.com/25Q32BVSIG+4MB-FLASH
the Soc of it is an broadcom 5356
i think i probably just bought an RT-N10+.
It's weird because it don't have the FCC code or something. I've checked asus site, and last Fw for both RT-N10 and RT-N10+ is exactly the same version 2.1.1.1.70.
Pls give it a look, probably this model is new and dont have support for dd-wrt.
Post some info guys!
Thanks |

Serial adapter I have too, but I don't know how to invoke serial bootloader. I can't find documentation for broadcom 5356. Best regards and sorry for my english... |

| | Posted: Tue Dec 26, 2017 11:36 Post subject: | I got it into recovery by holding the 'reset' button actually.. ( before powering up).
Flashed with the 'Firmware Restoration' utility. (Successfuly, but the LEDs show the same, no WLAN/radio ON and no web-GUI access... )
At first, it was only the web-page of the router that was faulty - it was incomplete... then, after several 'procedures' I seem to have bricked it altogether ....
| Quote: | Power off the RT-N66U.
Press and hold down the WPS button.
While holding the WPS button, plug in the power cable to turn RT-N66U on.
Keep holding the WPS button for 30 seconds before releasing The router should reboot.
Congratulations. The NVRAM has been cleared. |
