Phone is frozen on start up screen

don't use WPS -- it is very insecure.
U may need to do a factory reset on the router and reconfigure the router if u can't log into it.

Hard Reset: 1.Power OFF the handset. 2.Now press and hold the Volume Up, Muve Music key and the Power keys for 10 seconds. 3.A test screen (Triangle / Exclamation mark) will be displayed as below. 4.Press the Volume Up and Volume Down keys simultaneously to access the System Recovery screen. 5.Scroll using Volume and select "Wipe Data/Factory reset" and press the Muve key. 6.Scroll using Volume and select "Yes - delete all user" and press the Muve key. 7.When complete the system recovery screen is displayed. 8.Select "reboot system now" and press the Muve key. Master Reset: 1.Tap the Menu key 2.Tap Settings 3.Scroll to and tap Privacy 4.Tap Factory data reset 5.Read the message about erasing data 6.Tap Reset phone 7.Tap Erase everything.

I'd assume its a mixture of both. If the app wasnt properly coded for your phone it may have incompatibility issues. Short of changing the version of your Operating System, i dont see how else you can get it to work. Try contacting the app publishers, see what they say.

Hey i've been workin on these ZTE phone and i guess all u need to do is a reset. But the only problem is u will lose all ur data. all u gotta do is First power off the handset, press the Camera key + Power on key +Down volume key together at the same time.
when restart the handset,When display "ZTE", press the Menu key at the bottom of the screen;
Choose "Wipe data/factory reset" through volume key
Press "Camera" key to confirm the above item
Choose "YES...delete all user data"
Choose "reboot system now", handset will be restarted automatically and all the user data will be erased.
Now once its done ur phone will automatically configure all the factory setup and should work fine,

i think that is not match your phone so..............

I don't use move music so I just put a new one in. Since my SD card wasn't dead all the time, I was able to copy it off to my computer.

After inserting the new card, formatted it, and all I restored were my pics. That's all I needed.

Two other options you can try:

How u gonna hard reset it when its stuck on black screen?

This happened to me.... before you do this beware that your entire phone will reset... ok...let's get started.. while your phone is off hold the volume up button, muve music button and started button all at the same time until a yellow triangle shows up...next let the buttons go and press the up and down volume buttons until the reset screen pops up...use your volume keys to navigate to factory reset and hit enter with the muve music button.. itshould ask you if you want to reset your phone so scroll down to yes.. after this it should say at the bottom wipe successful or something of that nature... the phone should then cut off and cut back on itself.... that should do it.. hope this helps.

Same problem.... No solution...
