@jackxl: Please make sure you have provide power to the beacon and connect its VDD back to the nRF51 DK programming port as VTG. Note that the programmer on the nRF51 DK only support 3.3V, you need to use 3.3V for your beacon.

Do you see the same issue on other beacons ?

Could you please provide the log you get when you call nrfjprog --recover --log ?

I tried it, but I can't see the chip. It's blink and disapears, so I can't click on recovery button. If I use nrfjprog --recovery It will write "oparation could take 30s" or something like that and nothing happend.

You can use nRFgo studio to recover a device (= complete flash erase) with a jlink.
