How to restore jailbroken iPhone stuck in recovery mode without iTunes? I have a jailbroken iPhone 4 running on iOS 7.1.1. I checked Cydia and updated a few tweaks and since that update, my tweak called "f.lux" wasn't working so I deleted it. After deleting it, I would swipe to unlock my home screen but my phone would just shut off and restart. Restoring it in iTunes didn't work and errors would always pop up. I tried using TinyUmbrella and it didn't work. I also tried downloading an ipsw file but that doesn't seem to work either. Do I just need to buy a new phone or is there a way of fixing it?
It’s not possible to do that without iTunes.

If you have a PC or Mac with iTunes installed, you can bring the device in DFU mode by performing the following steps:


Connect the iPhone to your computer
Press and hold the Home button and the Sleep button at the same time
After 10 seconds, release the Sleep button
Continue holding the Home button until this iTunes message shows up: "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes"




You can then restore it to the latest iOS version. Please be aware that this will erase all the data on your device and will restore it to the latest iOS version (iOS 8.1.1 as of Dec 1st, 2014).

Please note: In DFU mode, the iPhone’s screen will remain black until you invoke the firmware restore. If it shows a "Connect to iTunes" screen, you are not in DFU mode but in recovery mode.
