you need to make sure that the softdevice version and your application start address are compatible. Which version of softdevice are you using exactly S!30v???. Looking at the log your application start address seems to be 0x1D000. Make sure you have softdevice version that expects application to start at 0x1D000.

The latest softdevice S130v2.0.1 have application start address at 0x1B000.

You need to download softdevice here
change the application start address and ram as mentioned in the release notes given in the zip file you download above.

Flash: 108 kB (0x1B000 bytes). RAM: 4.95 kB (0x13C8 bytes) (minimum required memory - actual requirements are dependent upon the configurationchosen at sd_ble_enable() time).

That SDK is too old. You may need to go to nordicsemi website to download.

Yes, you need to flash Softdevice first. This is only require once unless softdevice is overwritten.
