    Default How to check iBoot (bootrom) version

    iBoot is the bootloader on iPhone OS devices. iBoot acts on restore while iPhone is in Recovery Mode, iBoot makes sure that you are flashing a firmware version greater than or equal to a current one. If you are not, iBoot will not allow the restore to proceed. Because of this, firmware downgrading must be done in DFU mode.This means if you need to restore your iPhone to current version simply put the iPhone in recovery mode and iTunes takes care of the rest but if you need to downgrade your current firmware to lower one you need to put your iPhone in DFU mode.

    The old iBoot version was 359.3 and the new version is iBoot 359.3.2.

    There are a few methods to check which iBoot version you have:

    1.Serial Number Method :

    Check at the 3rd, 4th and 5th numbers in your serial number. If your serial number digits are "939" OR LOWER, its OLD bootrom. If you're serial number digits are "940" or HIGHER, its NEW bootrom.

    but to be 100% sure

    2. Using DFU Mode:

    Windows:

    1. Put your iPhone into DFU Mode
    2. Right Click on My Computer > Properties > Hardware (tab) > Device Manager
    3. Select the plus arrow for "Universal Serial Bus (USB) Controller"
    4. Find "Apple Mobile Device USB Driver", right click and select Properties
    5. Go to "Details" and find "Device Instance ID"
    6. Scroll through the string and you'll eventually find the bootrom version (iBoot)
    7. If it's 359.3 is OLD bootrom and you DO NOT require a tethered jailbreak. If it's 359.3.2 its NEW and you DO require a tethered jailbreak.

    Mac:

    1. Put your iPhone into DFU Mode
    2. Open "System Profiler" and go to Hardware > USB (menu on left)
    3. At the top right under “USB Device Tree Panel” click “Apple Mobile Device (DFU Mode)”
    4. In the upper right corner look for the information “string on the Serial Number.”
    5. At the bottom you will find the description BootRom version (iBoot).
    6. If it's 359.3 is OLD bootrom and you DO NOT require a tethered jailbreak. If it's 359.3.2 its NEW and you DO require a tethered jailbreak.
