Device Name shows as "N/A" after changing bootloader

Question

Hello, 
 my application hex used to work fine before i change my bootloader and softdevice
now after falshing all the hex including the application , it is advertising as
N/A i can connect to it and am still getting my service. 
 Q1)All work fine except it is advertising as N/A. This same hex used to advertise fine
before boot loader change ? 
 Q2) when i change the bootloader i have used boot loader_setting .hex that was mentioned in other forum to skip the validation (crc check). do i have to do this everytime , even though my application is valid ? 
 Looking forward to your Answer

Hi Brook,
Which tool/app did you use to scan and read the advertising packet ?
Have you try to cross check on other scanner ? 
 Q1. Are you sure you have jumped to the application or it is still in bootloader ?
I'm suspecting it could be the issue on the scanner. You can also use the sniffer to track packets over the air.
You mentioned you updated the softdevice, have you modified your application so that it's compatible with the new softdevice ? Could you give me more information about the version of the softdevice you replaced and the new one ? 
 Q2. If you don't write anything to the CRC value in the bootloader setting the CRC check will be skipped. By default our bootloader doesn't write CRC value in.
