Hello everyone...
I need some help trying to recover my TPWRT3600 router, but I am seeing some errors in putty, serial communication, as if the serial port speed is wrong or the cables are bad but not. like:
The problem he's presenting isthat all leds flash at sametime, indicating corrupted firmware, right?
I started testing with 155200 and went down to 9600 and nothing working properly.
My serial / USB adapter is this one, I think it may have a problem, but testing loopback communication works correctly, like this:
I ask your help because I no longer know what to do - I recover routers normally with this serial port method (using putty) and the tftp server, but this time, I can't.
If anyone has any step by step, please share here with me.
what about tx/rx lines? your wires look thick- how long they are? have you tried this same adapter on that same board before it was bricked? i don't usually solder GND, instead just attach the wire to the USB or RP-SMA shield - these are grounded
Over the weekend, I'll get my notebook, add an SSD, and install Windows 7, because I have a USB / Serial adapter that works or worked perfectly on Windows 7, but no longer works on Windows 10 so I can be sure that communication works well or not ...
In that time, I can test the communication between Windows 10 on my current desktop with my 1043nd, which works fine right now, using the USB / Serial adapter which is actually my eprom recorder and can be jumpered to function as serial port or parallel port ...
Anyway, I will still resold the pins on the WDR3600 board and test the conituity between the pin and the negative terminal of eprom to check for efficient soldering, and tighten the cable terminals again (I don't think it's bad contact). but check it out).
I have a reasonable knowledge of router recovery, but with this one, I believe I am facing some more serious problem related to the hardware used - I don't know if it's on the router board, the eprom solder on the board, the adapter used, anyway, do not know yet...
Anyway, from Brazil, a "big hug" to everyone and post news right here on this topic.
