axi0mX muongorori kusagadzikana mubootrom bootrom yeApple zvishandiso, iyo inoshanda padanho rekutanga rekutanga, uyezve inoendesa kutonga kuBoot. Kusagadzikana kwakapihwa zita rekuti checkm8 uye inobvumidza iwe kutora kutonga kwakazara pamusoro pemudziyo. Iyo yakaburitswa yekubiridzira inogona kushandiswa kunzvenga firmware verification (Jailbreak), kuronga maviri maviri bhutsu yemamwe masisitimu anoshanda uye akasiyana mavhezheni eIOS.
Nyaya iyi ine mukurumbira nekuti Bootrom inogara mukuverenga-chete NAND ndangariro, iyo inodzivirira iyo nyaya kuti isagadziriswa mumidziyo yakatoburitswa (kusagadzikana kunongogadziriswa mumabheji matsva emidziyo). Dambudziko rinozviratidza muA5 kusvika kuA11 SoCs inoshandiswa mune zvigadzirwa zvakavakwa kubva 2011 kusvika 2017, kubva ku iPhone 4S kuenda ku iPhone 8 uye X modhi.
Iyo yekutanga vhezheni yekodhi yekushandisa kusazvibata yakatobatanidzwa mune yakavhurika (GPLv3) toolkit. , yakagadzirirwa kubvisa kusunga kuApple firmware. Iko kushandiswa ikozvino kunogumira pakugadzira SecureROM dump, decrypting makiyi eIOS firmware, uye kugonesa JTAG. Iyo yakazara automated jailbreak yekuburitswa kwazvino kweiOS inogoneka, asi isati yaitwa, sezvo ichida rimwe basa. Parizvino, kushandiswa kwacho kwakatogadziridzwa kuSoCs s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011 uye t8015b, uye mune ramangwana ichawedzerwa, 5x8940x5s, 8942x5, 8945x5, 8747x7000, 7001 tsigiro. s7002l8000 x, s8001l8003x, t8012, tXNUMX , sXNUMX, sXNUMX, sXNUMX, sXNUMX uye tXNUMX.
