Cydia Impactor omogucava da uklonite jailbreak bez promene verzije iOS-a- 8.3/8.4
Saurik je napravio Cydia Impactor koji omogucava uklanjanje jailbreak-a bez potrebe da se radi restore i podize verzija iOS-a
Prakticno bi trebao da ga vrati na "stock" konfiguraciju.
Pogledajte EDIT u donjem delu posta gde se nalaze svezije vesti o podrzanim verzijama.
Cydia Impactor je u beta verziji - 0.9.16 i trenutno obuhvata iOS verzije 8.3 i 8.4...
Osnovna preporuka je da se, pre koriscenja ovog alata, uradi backup i da imate dovoljno baterije...

EDIT: Za sad jedino nije podrzan iPod touch 6...
Posle celog procesa, morate da aktivirate iUredjaj i da unesete sifru za iCloud ako ga pre celog procesa niste iskljucili.
Imajte na umu da se ovim brisu svi podaci sa telefona (obavezno uradite backup).
Postupak je potpuno jednostavan:
1. Pokrenete Cydia-u i instalirate Cydia Impactor
2. Backup iUredjaja preko iTunes-a ili iCloud-a
3. Iskljucite Find My iPhone (Settings > iCloud > Find My iPhone)
4; Napunite iUredjaj da ima bar 50% baterije
5. Pokrenite Cydia Impactor
6. Kliknite na "delete all data and unjailbreak device" na dnu displeja a potom na "Delete All".
7. Sacekajte da se zavrsi kompletan proces (duzina zavisi od broja podataka i tweak-ova koje imate instalirane)
Kad je sve odradjeno, pojavice se pocetni ekran za aktivaciju iUredjaja.
EDIT:
Beta verzija Cydia Impactora omogucava sve ovo na iOS 9.0.2...potrebno je da dodate Saurik-ov beta repo

Jos uvek nisu podrzani svi uredjaji i za sad se zna da funkcionise na 5C, 5S, 6, and 6+....
Ovo je ono sto je Saurik napisao po pitanju napretka
The main things I had to do for iOS 9 that were "risky" were to verify that there wasn't anything horribly unexpected in the untether, and in fact there was: it patches the dyld shared cache, which is one of the few files I didn't bother coming up with a strategy to repair. I managed to build a mechanism for it that is able to do a two-stage commit even though it sort of updates the file in place, and I verified that it worked by doing a few back and forths of jailbreaking and then erasing with Impactor. And when I say that there are some device and firmware combinations it doesn't support, it isn't that it does something awkward: when you click the button it immediatelypops up a dialog box with a cryptic error message that means it can't even begin to think about working on the device as there is no available "full" OTA update.
