if its getting stuck at enabling memory writes, add the NOEMW switch. Rumor has it that tjtag we developed on an rt.. Why are you using the skip detect. The processor should be recognized.

However and most important, why do you need jtag to fix that router? On the cd is a recovery tool that to my suprise, works.

with the last version of tjtag + universal jtag in bufered mode i was able to turn alive my RT-N16

firs i cancelled the wholeflash, then i download a CFE for rt-n16,i change the mac adr with mine.
second, flashed the CFE(3 hours)
third, flashed this file ftp://dd-wrt.com/others/eko/V24-K26/svn15453/dd-wrt.v24-15452_NEWD-2_K2.6_mini_RT-N16.trx with TFTP then this ftp://dd-wrt.com/others/eko/V24-K26/svn15453/dd-wrt.v24-15452_NEWD-2_K2.6_big.bin(webflash)
and hola my ASUS RT-N16 after seven months is again alive
