In Engineering Mode I have not changed LTE settings, so all is well with my IMEI, thanks. For modem firmware requires ROOT. Upon receipt of ROOT, I am losing the guarantee - is not a good option. Therefore, 4PDA topic does not fit. I calculated on the update of the MEIZU.

Rooting is an option for you. as per the meizu interaction i found rooting not void your warranty. if you are not satisfied with Global Rom flash a chinese A rom or a beta rom.
