Rooting unseccesful

A

AC Question

Hi,
I obtain a elephone G4 phone which I want to change ROM and change partition,
so to have more space for applications.

I have tried a few methods for rooting my device and non of them succeed, plus trying different PC's and USB cables and verifying debugging mode on.

sofwares which I tried were kingo root, iroot, flashify, twrp, rom manager, link2sd, which all result in freezing or no reaction (installing drivers is ok).

What can the problem be?
