Hello guys.... I need a lot help, please.

I have a R6300 Netgear Router; it was working fine for the past 6 months with dd-wrt.v24-K3_AC_22200 build.
For some reason I had to reset thne router last night and now it's messup...
I was able to flash stock firmware back into it; then I install DD-WRT v24-sp2 (02/25/13) mega 41M build.... dummy me (file from myopenrouter.com)

I need to go back to dd-wrt.v24-K3_AC_22200.

I'm able to connect and ping the router with no loss (TTL=64) but I'm unable to update the firmware from the webgui (it fails 100%); I also tried TFTP, SSH, Telnet all with no success either.

Router is on with a solid yellow light.
Please help
Thanks

check out tftp recovery.

first, hook up to the router by WIRED ETHERNET in case you already havent. do not power on the router yet.

first thing i would try though, is get tftp2, set it to flash FACTORY STOCK FIRMWARE, routers ip (try 192.168.1.1 first), number of tries to 10, and then click upgrade.

now power on the router and wait until you see upgrade flash. if you see "Upgrading Firmware", give it another 3 minutes or until all lights are well lit.

if this dosent work, you will need to do a serial recovery.

tftp recovery did not work.... Sad

so each one would be easier? jatag or serial recovery?

I open the router and I see 6 pins that looks like is for jtag.... right next from that I also see a square with 10 empty holes(connectors) which I'm guessing for a serial connection...

If I go with serial I would have to solder 10 pins....

Also there's no marks for any pins (grn, 3.3, tx, etc)

Can I buy this http://www.ebay.com/itm/310742466145 and use with the header with 6 pins on it?

Thanks

where did you get that idea? serial is 6 pins and jtag is 10 pins.

you will need to get the pins for SERIAL recovery. which is the 6 pins you see. and you will need to solder.

usually when i solder some pins on a pcb like a router, i put the pins in the hole and tape them down with black tape making sure that the pins are balanced and all standing straight. makes it easier for me to solder on the other side of the board because if i didnt tape them down, then they would fall out.

make sense? if not, i can show you a picture of what i mean.

You've got it backwards. Scroll to the bottom of this page.

Ok, so I looked the bottom of the page, it says:


J251
(GND) (RX) (TX) (3.3V)
pin6 pin5 pin4 pin3 pin2 pin1

But if I look my router (pic below) the J252 has 6 pins and the J251 has no pins but it has 10 holes.

My guess is that on my router I should use the J252 pins, right?

If so, can I buy this and use it with the serial instructions? (http://www.ebay.com/itm/310742466145)

and no soldering, right?

No soldering required. That looks like the serial port.
I just looked at Kong's picture at myopenrouter. His is just like yours. Wikidevi must be wrong.

After that type: flash -noheader : nflash1.trx. Then enter. I use tftpd32 by journin or tftp2.exe to push the firmware.
It should then upload it. Keep watching the console, when it's done, type Go. The router will reboot and should be fixed.

isnt it the other way?

i would set tftp2 to retry 10 times, set firmware (that has been renamed to nflash1.trx), and then click upload. then i would go over to the router and type the command. works every time on my side of things.
