I was see in download list https://dd-wrt.com/support/other-downloads/?path=betas%2F2025%2F08-22-2025-r62104%2Ftplink-tl-wr841hpv3%2F my router and flashed with factory to ddwrt bin.

You did flash back to stock first, right? Also, this device was never fully tested, it was a blind port.
No serial output for feedback from flashing DD-WRT for the developer to fix any problems that I
recall. If you don't know how to connect serial and get output, then we won't know what to fix.
When i press reset button goes reboot bliks all led than wps and (low)wifi led stays on and that continue to be untill i turn off power.Power led i think should be turned on,but its not.

You can't necessarily flash DD-WRT from OpenWRT because you may erase the bootloader if you're not careful. The commands in OpenWRT don't necessarily do what they are supposed to, and I am not going to advise anyone to do anything that I have not tested myself. Connecting serial is not that difficult, but you do have to solder the header pins in place or find a way to make the connections stable enough to work. The usual 115200 baud, 8 bits, 1 bit, N settings for PuTTY or other serial terminal application apply. Again, I do not have this device, so I do not know what you will see 100% for sure. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Thank you.Maybe is bootloader damaged by that flashing.Than ddwrt firmvare is good ?
my experience with Tp-link router is...always flash the stock firmware when moving form one to another ...and yes very likely you got into the trouble...serial output will give some insights but bootloader will not be fixed...it must be U-boot if im not wrong...
DDWRT should be fine but...as KP-69 noted it was a blind port..and not tested... _________________ Atheros

It seems that we must repeat:
