pHaseBanDowngrader - by Pedro Henrique Cavallieri Franceschi. (a.k.a. pH).


Para rodar o pHaseBanDowngrader, conecte via SSH ao seu iPhone e copie a pasta baixada (phasebandowngrader) para dentro da pasta "/Applications" no seu iPhone. OBS: A pasta TEM que se chamar phasebandowngrader, com letras minúsculas!

Para rodá-lo, entre no MobileTerminal e digite "login". O usuário é "root" e a senha é "alpine" por padrão. Depois, digite: "cd /Applications/phasebandowngrader/" e, em seguida, por final, para rodar o downgrader, digite "./phasebandowngrader".

Para checar a versão do seu Bootloader, mais informações aqui: Baseband Commands

(rode o at+xgendata no minicom)


To run the pHaseBanDowngrader, connect to your iPhone via SSH and copy the downloaded folder (phasebandowngrader) into the "/Applications" on your iPhone. Note: The folder MUST named phasebandowngrader in lowercase letters!

To run it, open MobileTerminal and type "login". The user is "root" and password is "alpine" by default. Then type: "cd /Applications/phasebandowngrader/", then, to run the downgrader, type "./phasebandowngrader"

To check your bootloader version, install minicom and run at+xgendata (see Baseband Commands for more info)
