My iPad 1 facing crash issues after installed and start running Infinity Blade 2, it’s can’t start up the game even reboot iPad. Then i searching internet and found that lot of Infinity Blade 2 gamers facing same problem as me especially running on iPad 1 and iPod Touch iOS devices.
Chair Entertainment and Epic Games have identify the problem and suspects due to running out of memory on their heavily laden iPad 1 and iPod Touch devices, this message already published on their Epic Games forum, now they are working to fix this issue and will submit a update to iTunes app store as soon as possible.
Well,i can’t wait to fix Infinity blade 2 crash issue and also don’t know when they can having a update on iTunes app store. If you same as me having Infinity Blade 2 crashes issue, you can follow below method fix it by yourself and let you iPad 1 running game smoothly without any problem (at least work for me).
Infinity Blade 2 Crash Fix
1.Use ifunbox connect to your iPad 1 and navigate to /var/mobile/Applications/InfinityBlade2/SwordGame.app.
2.There are total 4 MP4 video files in m4v format.
- Startup.m4v
- Starup_Long.m4v
- Logo.m4v
- IB2_Prison_Open_cine.m4v
3.Now delete Startup.m4v,Starup_Long.m4v and IB2_Prison_Open_cine.m4v these three files or rename m4v file extension to others, here i change these three m4v file extension from m4v to m4v2 (Please backup before any amended).

This method is disable m4v video file and don’t let it play automatically with use less memory. Now i can play the game on iPad 1 without any problem.

Hope can help you all.
PS: Infinity Blade for iPhone and iPad become free for limited time (14/2/2013), download the game.
