Cum se face downgrade iOS la iPhone 4?


Recommended Posts


Probabil multi dintre voi ati facut actualizare la iOS 7, nu va place, dar ati facut greseala de a nu salva blobs-urile si totusi vreti sa faceti downgrade. Teoretic, nu puteti face downgrade fara blobs, dar practic puteti si fara ele! Tot ce trebuie sa faceti, este sa intrati aici http://www.geeksn0w.it/GeekGrade/download.html si sa descarcati una dintre versiunile de iOS la care vreti sa reveniti ulterior. Procesul este putin complicat, dar daca urmati instructiunile in tocmai, ve-ti reusi. 

Descarcati iReb de aici https://github.com/iH8sn0w/iREB-2.0/releases/r7/1097/ireb-r7.zip si extrageti ce este in arhiva. Acum descarcati redsn0w http://www.iphonehacks.com/download-redsn0w. Daca aveti instalata o versiune mai noua de iTunes, dezinstalati-o si instalati iTunes 11.0. 32 bit: http://api.ios.icj.me/v2/iTunes/Windows/11/url/dl. 64 bit: http://api.ios.icj.me/v2/iTunes/Windows/11/64biturl/dl. Descarcati versiunea potrivita dispozitivului vostru, ve-ti avea nevoie de  GeekGrade_IPSW si Boot_IPSW. Fisierul Boot_IPSW este necesar deoarece dupa downgrade, telefonul va intra in recovery si va cere sa-l conectati la iTunes. La fiecare repornire a telefonului, o sa fiti nevoiti sa il porniti cu Redsn0w, pentru ca blobs-urile sunt incorecte, iar telefonul verifica acest lucru. Procedura de boot cu Redsn0w:
