Kutholakale ubungozi ku-bootrom yawo wonke amadivayisi we-Apple anama-chips asuka ku-A5 kuya ku-A11

Umcwaningi i-axi0mX kutholiwe ubungozi kusilayishi se-bootrom samadivayisi we-Apple, esisebenza esigabeni sokuqala sokuqalisa, bese sidlulisela ukulawula ku-iBoot. Ukuba sengozini kuqanjwe ngokuthi i-checkm8 futhi ikuvumela ukuthi uthole ukulawula okuphelele kudivayisi. Ukuxhaphaza okushicilelwe kungase kusetshenziselwe ukweqa ukuqinisekiswa kwe-firmware (i-Jailbreak), ukuhlela ukubhuthwa kabili kwamanye ama-OS nezinguqulo ezihlukile ze-iOS.

Inkinga iyaphawuleka ngoba i-Bootrom itholakala kumemori ye-NAND efundwayo kuphela, engakuvumeli ukulungisa inkinga kumadivayisi asekhishiwe (ukuba sengozini kungalungiswa kuphela kumaqoqo amasha wamadivayisi). Inkinga ithinta i-A5 ngokusebenzisa i-A11 SoCs esetshenziswa emikhiqizweni eyakhiwe phakathi kuka-2011 no-2017, kusukela ku-iPhone 4S kuya kumamodeli we-iPhone 8 no-X.

Inguqulo yokuqala yekhodi yokusebenzisa ubungozi isivele ihlanganiswe nekhithi yamathuluzi evuliwe (GPLv3) imfu, eklanyelwe ukususa ukubophezela ku-firmware ye-Apple. Ukuxhaphaza okwamanje kukhawulelwe emisebenzini yokudala ukulahlwa kwe-SecureROM, okhiye bokukhipha ukubethela be-firmware ye-iOS, kanye nokunika amandla i-JTAG. Ukugqekezwa kwejele okuzenzakalelayo kokukhululwa kwakamuva kwe-iOS kungenzeka, kodwa akukakaqaliswa ngoba kudinga umsebenzi owengeziwe. Njengamanje, ukuxhashazwa sekuvele kuguqulelwe ku-SoC s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011 kanye ne-t8015b, futhi ngokuzayo kuzonwetshwa ngo-5x8940 5x8942, 5x8945 usekelo lwe-5x8747 s7000l7001x, s7002l 8000x, t8001, t8003, s8012, sXNUMX, sXNUMX, sXNUMX kanye ne-tXNUMX.
