Hi
I install dd-wrt.v24-21676_NEWD-2_K2.6_mega on my RT-N16, then i log on putty console and make the biggest mistake.
i give this tree comands in console:
erase nvram;
erase dd-wrt;
erase cfe
and of course reboot, then my router refuse to start up.
I have no power light, only lan port light and i can't enter to recovery mode, the restore button doesn't work.
I also tried a ca-42 cable but i can't see nothing on serial connection on putty (i set the right port and bud rate).
Any chance to revive the router?
Thanks

It can only be rescued by taking out the flash chip and reprogram the CFE using an external programmer.

Might be possible using JTAG. Standard recovery methods certainly won't work if you erase the cfe though.

I don't think that they are doing it on purpose! Smile

It really does get confusing as to which firmware is for which router (except for the trailed builds - they make it nice and easy!). You have k2.4, k2.6, VINT, NEWD, NEWD2, NV60K, NV64K, etc, etc...

Then if you try to read and actually understand the "peacock" thread - as the one user just loves to constantly point out instead of actually helping folks, that confuses people even more. Then, of course, we have the Router Database, which everyone says not to use, but it is right in your face on the main page! Then we have SP1 labeled as the "stable" version... Really, it's no wonder there are so many bricks.

The whole purpose of this board to ask questions and get help, isn't it? I swear that there are certain users who would rather the whole site only be the damn Peacock thread! The peacock thread is not a substitute for personalized help...

Sorry - got off on a tangent a little bit there!!

but, if you do not have the possibillities to recover, you´d better dont touch experimental Builds. JTAG isnt a garantuee for newer routers. This Forum is full of:"i have bricked my unit" threads Razz

I see no reason for erase cfe. Nobody on this forum suggests that you should erase cfe (perhaps for older G routers there was a need to do it in order to write a new cfe, but there is no such need for a RT-N16).

If it helps at all, I have a CFE backup for this model. Firmware should be recoverable from the software CD bundled with the router, as far as I know.

See http://www.dd-wrt.com/wiki/index.php/Asus_RT-N16#If_you_have_bricked_your_Asus_RT-N16 for further instructions. The serial connector might be your best bet since you now have a copy of the CFE.

Just use ASUS Wireless Router Firmware Restoration Utility. You can download this tool in ASUS website. No ttl, no jtag need.

That would be fine had it only been the firmware that was erased, but removing the CFE is essentially the same thing as removing your computer's BIOS. The router isn't going to be receptive to the firmware recovery because it has no way to start up beyond simply powering on.

I understand now, thank you. Smile
