I want to point out that this will not reflash your radio firmwares. If you got the update and run this you will end up with new radio firmware but with OS build EA29.
This could mean many things -
1. All the changes for LTE were firmware based and everything will be great
2. Some of the changes for LTE were on the OS and you wont get the full benefit
3. Some changes for LTE were OS based and now with the incorrect firmware there will be bugs since you are running a mismatched set of code
