Tshawb nrhiav axi0mX muaj qhov tsis zoo nyob rau hauv bootrom loader ntawm Apple li, uas ua haujlwm ntawm thawj theem ntawm khau raj, thiab tom qab ntawd hloov kev tswj mus rau iBoot. Qhov tsis muaj zog yog hu ua checkm8 thiab tso cai rau koj kom tau txais kev tswj hwm tag nrho ntawm lub cuab yeej. Qhov kev tshaj tawm siv tau tuaj yeem siv los hla kev txheeb xyuas cov khoom siv (Jailbreak), teeb tsa ob lub khau raj ntawm lwm OSes thiab ntau yam ntawm iOS.
Qhov teeb meem yog qhov tseem ceeb vim tias Bootrom nyob hauv kev nyeem nkaus xwb NAND nco, uas tsis tso cai kho qhov teeb meem hauv cov khoom siv uas twb tau tso tawm lawm (qhov tsis muaj peev xwm tsuas yog kho tau hauv cov khoom siv tshiab). Qhov teeb meem cuam tshuam rau A5 txog A11 SoCs siv hauv cov khoom tsim los ntawm 2011 thiab 2017, xws li iPhone 4S mus rau iPhone 8 thiab X qauv.
Ib qho kev qhia ua ntej ntawm cov cai rau kev siv qhov tsis zoo twb tau muab tso rau hauv cov khoom siv qhib (GPLv3) , tsim los tshem tawm kev khi rau Apple firmware. Qhov kev siv tam sim no txwv rau kev ua haujlwm ntawm kev tsim SecureROM pob tseg, decrypting cov yuam sij rau iOS firmware, thiab ua rau JTAG. Lub siab automated jailbreak ntawm qhov kawg iOS no tso tawm yog ua tau, tab sis tseem tsis tau siv raws li nws yuav tsum tau ua hauj lwm ntxiv. Tam sim no, qhov kev siv tau raug hloov kho rau SoC s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011 thiab t8015b, thiab yav tom ntej nrog kev txhawb nqa 5l8940, 5l8942 thiab yav tom ntej s5l8945x, s5l 8747x, t7000, t7001, s7002, s8000, s8001, s8003 thiab t8012.
