I'm posting this here because it's the 1st page that comes up when you google RNX-GX4 bricked (xfta-router)

I was running another firmware on this router and tried to upgrade it, and it bricked.
for over an hour i tried the recovery procedures and it failed..
I googled for a while and saw many people give up.
and then I got it figured out and working (repeatable)
so i figured i'd post up to help out others who get in this situation..

1st thing you should know is this router is very time specific in the recovery procedure, you have less than 5 seconds to send the firmware and it has to be a certain time or else you get nothing.

so here is how you do it.

1) set IP to 192.168.1.xx (.33 is suggested, but i dont think it matters)
2) hook cat 5 cable to router port 1 (not wan port) and to your pc/laptop
3) get a KNOWN working firmware or the stock rosewill firmware ready
4) get tftp32 up and running
5) place the .trx file in the root of the tftp32 folder
6) configure tftp32 CLIENT
host 192.168.1.1
select the file you just put in the root
port 69
and dont touch anything else here
7) open a dos box (cmd) and type ping -t 192.168.1.1
note: i saw instructions somewhere, where someone said to do this, but said not to hit enter.. this is wrong. you need to see what's going on to know when to send the firmware
go ahead and hit enter in your dos box.
you'll start seeing destination not founds

9) keep your tftp32 and dos box open and side by side so you can see and interact with them
10) take a saftey pin or other sharp object, unplug in the router, insert saftey pin in default hole in the back, hold it down and plug in the router.. you'll see the led's light up, as soon as they start blinking count to 10 and let go of the saftey pin and the blinking will stop

11) watch the ping window, after about 30 - 60 seconds you will see a respond from 192.168.1.1
AS SOON AS YOU SEE THE 1ST RESPONSE click "put" on your tftp32 window

If you do not do this on the 1st or 2nd response, you will have to start all over.

the router only responds for about 4-5 seconds and then it no longer responds.
which is why if you are doing it blind (no ping windows) you are pissing in the wind with this process

if you did it correctly, you will send the trx file being Tftp'd over in a few seconds.

do NOTHING but sit there and watch your ping window about 1-2 minutes, you'll start to see responses from 192.168.1.1

at this point you can stop thinking about throwing this router in the garbage.

i hope this helps someone who googles through
