Hey guys,
So a few days ago I was trying to install an app from AppCake I had downloaded on my iPhone 5S running Cydia on iOS 8.4 but it said I needed AppSync installed to continue. So I got AppSync and tried installing the app. The power went off and I can not turn my phone back on - like at all. I've tried to put it in DFU mode and Safe Mode but like I said it cant turn on anymore. However, if I let it charge, it shows the low battery logo (but it doesn't show the charging part underneath the battery logo) and the apple boot logo and then it goes black again then back to the low battery icon and it just loops the battery, apple logo, black screen, battery, apple logo, black screen, etc. At this point I knew I would have to restore it so I plugged it into my MAC computer and put the iPhone in recovery mode to try to restore it, but for a reason I don't know it said that the iPhone could not be restored, you have to update it blah blah. So I tried updating it thru the MAC but it said this iPhone can not be updated please restore blah blah with an error code of 2001. I honestly don't know what to do. Is there anything you guys can think of that I can do to fix my phone?? A semi-restore? Another software that can fix it? I neeeeed help!
