Default A thought about Bootloader update from 4.1.2 to 4.4.2

Hi everyone,I'm a user of N5110 China mainland version.For many reasons,many Chinese users have eagernesses to flash newest foreign official Roms,so do I.
Yesterday I downloaded 4.4.2 for a try with Odin v3.09.As usual,it failed when flashing sboot.bin.I made a try flashing sboot.bin/tz.img/boot.img only.Failed again.
So I made a Rom compare between China mainland 4.1.2,UK 4.2.2 and 4.4.2 and found out that China version has a special file hidden.img when UK has two tz.img/sboot.bin
You may say“isn't there has CM11?”Yes,CM11 has great efficiency and excellent experience.But what I can't tolerate is horrible battery management.For a user who is often at outdoors,it doesn't fit me at all.
Odin doesn't have “force flashing”like Nokia Symbian,So I want to discuss if we can upgrade bootloader which can help people who are suffering no Wi-Fi in official 4.4.2 Roms.We Chinese people are bothered about this now.

(Am I posted to a wrong board?)
