z750 flash/debrand help please!

Hey I recently bought a Z750 from AT&T for my mother and I wanted to flash it for her since the AT&T software sucks!

I debranded my w580 with se tools (I loaded in new "FS" and "MAIN" files). should I debrand the z750 in the same manner?

any help would be great thanks!

No you can't.

Z750 is a DB3150 (A2 platform). Only with setool box or servers like D-Client or D-Unlocker.

Use search option.
