Hi guys, i have this weird question to ask, which i can not find no one to ask before me:

Can I make a jailbroken iPhone 4 on iOS 7.1.2 stop loading springboard ?

What i want to achieve: I have switched from this iphone 4 to a new Iphone 6s, and I have a rich music library which i listen a lot and I am sort of "audiophile"(for the ones that haven't heard this before, an audiophile is someone who enjoys listening to extremely high quality records). For a portable device, the iPhone 4 is actually performing very well on that aspect, but i cant tell the same for the iPhone 6s. I have searched over the internet about this loss of volume and sound quality on the iphone 6s, and it turns out that all of the iPhones after iPhone 4s have worse DAC's(digital audio converter - the part responsible for producing analogue audio). I haven't test that, but one's for sure my iPhone 4 sound significantly better that my iPhone 6s. So i want to make the music playback in my car goes trough the iPhone 4 DAC, but to be able to manage tracks from my 6s. I found this awesome jb tweak called AirSpeaker, which turns your ios device into airplay speaker so my task seems achievable:
1. leave the iPhone 4 in the car connected to the car's stereo.
2. connect the iPhone 6s to it as an airplay speaker(there will be dedicated wi-fi network).

i have tested this setup and it is working however, there is some serious lagging and audio tearing caused by the slow performance of the iPhone 4. It gets even worse if i swipe the spring board or open some app.

So is there some way i can stop the ui of the iphone so it frees up resources for the only task that i am going to make him do ? AirSpeaker tweak makes its dedicated Daemon that takes care of everything - no need for app launching. I cant sleep the device because the daemon stops executing.

Ideal setup for the iPhone 4 would be to stay unlocked constantly but with black screen as if it is locked, and to control it over ssh.

Thanks for the help :)
