i think you didnt fully updated your 3ds to x.x.x-28, its not the savest way, because it will create a frankenstein 3ds. Because of that i think people should only update nver and cver while there are no better ways. this way you would still need hans, but its saver. Also people should note the systemversion before they install newer cver and nver versions to restore it easier after there is a better way.
I know a Frankenstein-3DS FIrmware isn't the best idea, but it works.
As long as it works, I don't care if it's a "weird" partitial updated Firmware.
I'm able to connect to the eshop, I can use the Miiverse and I can play online without problems

If I had bricked it with only Updating NVer, I had used my NAND Backup to restore my 3DS but it wasn't necessary.
CVer changes the 9.0.0 Part of my N3DS to 10.3.0, right?
Lel, I could troll some idiot people and tell them: Hey guys, look at this, I've the newest firmware and I can use the Kernel Exploit. Lol Lol Lol
