I will tell you the method that worked for me
Firs of al I highly recommend you to use the v.3 version of sp flash tool,it worked for me then download q mobile stock ROM from www.needrom.com select q mobile and go to page 2 and there u will see q mobile stock ROM select it and download it, once u have downloaded just extract to desktop and then open sp flash tool and then I formated whole drive with sp flash tool and then try format all and download option if that doesn't work try firmware update option, if even that dosent work try download option and hit download then attach your phone with USB cable to your computer and it will be detected as v com driver and then the download will start, once the download will finish there will appear a green tick mark just close it and power on your q mobile z4 if u see the q mobile logo then just press volume down + volume up + power button and you will go to factory mod then clear data and your q mobile will start and will work 100% ...
I don't know if this method will work for you I don't know what you've done with it, this method just worked for me and know my z4 is working like a charm

[Q] ALCATEL OT-983 Unbrick

Hi there. I tried everything... and i really mean everything but i cant manage to unbrick this phone.
I installed alcatel recovery 1.0.0.0.0. but i can only scroll the options. the home button doesnt make the selection so i cant choose an option.
i also tried to install the boot.img , system.img by fastboot but it doesnt work. it gets stucked at the boot. I also tried the official alcatel firmware update software but it apears the message that i already have the latest firmware. I tried also to change the "version" to cheat that software but mtk tools doesnt detect the phone so no scatter file....
can someone help me ? i need a working recovery or something else... iam out of ideas ...
