Hey ! My name is Mark , and I have a big problem with my iPhone 5s.
I jailbreaked the phone a week ago , and it worked , but I doesn't have the Cydia app. I tried to jailbreak again , and well , not Cydia again . I Tried perfecty third , at least , the third was not working. I tried to restart my phone , but it have the "endless boot screen" , that means it starts to the Apple logo and loop. I tried to connect with iTunes , but it don't recognized it. I Tried to force restart and that works. But unless I tried to restart , endless boot starts again. I Tried today the Recovery mode , and I that works for 10 minutes , I select on the iTunes the reset , ios 9.1 come up , and it works , but at least... Endless boot comes again. I Tried to do this twice , but then "Error 39" come up. And now, can't reset my phone. And yes , I jailbreaked at 9.0.2 , Taig Jailbreak. Any idea to fix ? Or trash?

That's the risk when you root any device. Unless you are REALLY good at this (most who think they are, aren't). You could try the store... plead ignorance and hope they don't notice.

I live in Hungary , there's no Apple Store :D
I buy my phone in a local gsm store.
At least , I think when I came there , they just say : "We will not help you , because jailbreak."
But the Jailbreak was perfectly good , but I crashed it . Its unfortunately my mistake , not the Jailbreak's.

OK, that complicates it a lot.

Have you tried to look for an unmodified image you can use to "recover" from. That's usually the means of last resort on an Android device when someone messes it up somehow.
