Honor 4C LTE

Hi!
Honor 4C has kirin 620 processor.

And based on the design documents it support the following:
GSM / TD-SCDMA / WCDMA / TD-LTE /LTE FDD /Cat. 4 LTE for speeds up to 150Mbps.

But the Honor 4C not support the LTE...
My question is it possible somehow with custom rom/driver to activate LTE?

Thx.
