Buttonless DFU - LED 3 blinking after flash

[parco]

With SDK 14:

If I flash in this order:

1. softdevice_s132.hex

bootloader_secure_ble_debug_withbonds_s132.hex 3. ble_app_buttonless_dfuwith_bonds_s132_with_setting_page.hex

Then complete a DFU with this application:

ble_app_buttonless_dfu_without_bonds_s132_with_setting_page.zip

The board goes into an unrecoverable state. Holding button 4 and resetting will not get me back to DfuTest. There seems to be no way of recovering unless I erase completely and start over.

Why does this happen?
