Hi everybody,
My router is WRT320N its bricked and I get only blinking power led.
I tried Jtag.here is what I did up to now.
1-I erase nvram and kernel then restart still dont ping.Since I dont ping,I can not use tftp.exe.
2-I flash cfe file. I download wrt320 cfe file and using hex editor I change mac,serial,p/n number and flashed but still I cant ping.
3-I use the command as wholeflash in JTAG. I download ddwrt firmware for WRT320N changed its name wholeflash.bin. I wait more than 4 hours but after flashing still I cant ping.
whole flash is not firmware file. wholeflash is ALL like cfe, nvram and linux. you did overwrite your cfe with nonsense. _________________ RT-N66U @ Build 25697M K3.10.63

why /fc:22 ? let tjtag detect flash itself. fc22 indicates 2 mb flash (latest tjtag version). wrt320n has 8 mb. if possible, make a video of the procedureand upload it. or take several pictures.
md5sum your cfe file, flash it, rebackup it and compare both files with md5sum.
however, for full diagnoctic, serial output is needed. _________________ RT-N66U @ Build 25697M K3.10.63

I am using 3.01 version. In 3.01 " fc22 " 8mb serial flash.Tjtag does not detect flash if I let. I payed 5 dollars but my link didnt come thats why I use old program which I found on web.
I did what you said, before. I saw all data is 0000001a.

I think that version of jtag has a problem with the 320.. It has been a while.. last time I had to fix one, I just pulled the flash chip and programmed it externally. _________________ [Moderator Deleted]
