Could you explain what did you do when you try to "But when I try to program with nRF tool again" ? with step by step.

Note that the service you pointed to, is only to be used with the bootloader from SDK v11 and earlier. If you are using SDK v12 bootloader, you should use the DFU buttonless service from SDK v12 as described here.
