Unable to open game ios

no matter install or reinstall the game I got a black screen first time I open the game
I got jailbreak for my device is that a problem ?
iphone 6 plus ios 8.1

 

Somebody please help admin !!

 

Jailbreaking definitely makes compatibility more complex... It's like putting Windows Vista on your iDevice. =P
Usually, if you jailbreak, they really can't help you since it adds too many variables to give you accurate advice. Nonetheless, you could try all the typical client-side attempts (I'm sure you've done most of these already prior to making this thread, but it never hurts to review the flowchart):
Try closing down the app along with all others that may be running before relaunching. (I doubt it's a memory issue, but, eh, jailbreak is a wild card.)
Reset your device by holding down the home button and power button simultaneously before relaunching.
Try to uninstall/reinstall.
If you are willing, you could also remove jailbreak and then try again.
You take the phone and put it in a box. After that, you put that box in another box. Finally, you SMASH IT WITH A HAMMER. (Props if you get the reference!)

 

Ha ha thank you so much !
I will try safe mode this time if it still dont work I gonna smash my phone probably

 

Okay !

Okay ! thank you so much !
however is there another way i could fix my driver by modifying my ROM without updating my ios ?

 

O

Or maybe your team could modify the binary file for ios 8.1 to make it work or otherwise I would need to do that myself and I dont no its legal or not
