Download Open Source checkm8

“What I am releasing today is not a full jailbreak with Cydia, just an exploit. Researchers and developers can use it to dump SecureROM, decrypt keybags with AES engine, and demote the device to enable JTAG. You still need additional hardware and software to use JTAG.”

“A bootrom exploit for older devices makes iOS better for everyone. Jailbreakers and tweak developers will be able to jailbreak their phones on latest version, and they will not need to stay on older iOS versions waiting for a jailbreak. They will be safer., as the researcher said.

“Maybe someone can figure out a nice way to use JTAG on iPhone without proprietary hardware and software. I and many others would be forever grateful if someone makes that possible.”

Disclaimer

  • This is BETA software.
  • Backup your data.

This tool is currently in beta and could potentially brick your device. It will attempt to save a copy of data in NOR to nor-backups folder before flashing new data to NOR, and it will attempt to not overwrite critical data in NOR which your device requires to function. If something goes wrong, hopefully you will be able to restore to latest IPSW in iTunes and bring your device back to life, or use nor-backups to restore NOR to the original state, but I cannot provide any guarantees.
