Thanks. That sounds like useful info.
I almost flashed one of my TP-Link devices during a power outage today.
I.e. i was just about to hit submit when the power went off.
So now I'm simply subscribing to this thread as something to try if needed.

Cheers smile

Thank you for your help,

Follows the historical Wireshark first pressed by just 3secs and the second held.

In other attempts to connect CP2102 and the puty mostando "strange characters" when I held the reset longer he made several consecutive uploads and took longer to restart, at another time it did not happen more.ento isso não aconteceu mais.

PunBB bbcode test

from line 15723   rom transfer seems ok.

after flashing the board should restart itself and boot into OpenWrt.

because frimware is working .

unplug the power, wait a bit, replug, the system should be freshly working...

please wait 1-2 minute for ready router.

if still router seems not working  ;

maybe rom.bin file is damaged or wrong file. please check  md5.

it must be openwrt or factory image file.

please try another .bin file

regards.
