Summary
BootNeuter gives you total control of your first-gen iPhone's S-Gold bootloader and baseband.
It's an application you run right on your iPhone that lets you:
Neuter your bootloader
Unlock your baseband
Reflash your bootloader to 3.9BL or 4.6BL no matter what version you're at now (even if you're at 3.8BL)
Fakeblank your bootloader to let you run serial payloads directly on your S-Gold
Screenshot
Neutering
A neutered bootloader gives you absolute control over your baseband. The restrictions normally applied by the bootloader are completely lifted! With a neutered bootloader:
The baseband is no longer integrity-checked Can be patched (unlocked or other custom modifications) 4.6BL will even run with patched baseband – no need to revert to 3.9BL even with most recent firmware Secpack restrictions are removed You are free to downgrade your baseband using bbupdater without having to run ieraser/ienew first. No longer does the “greater than” (4.6BL) or “greater than or equal” (3.9BL) rule apply. You can arbitrarily go up and down regardless of what secpacks you use. Secpack signatures are ignored The RSA encrypted header is no longer checked for correct hash values by the bootloader The *.fls files can be patched and fed to bbupdater directly A copy of the last used secpack will be saved at a03c0000, retrievable via norz or similar dumpers. Not that secpacks even matter anymore.
Unlocking
BootNeuter gives you the option to unlock your 1.1.4 or 2.0 1G baseband. An unlocked baseband is patched, and would normally fail the integrity check done by the bootloader on recent firmware releases. The anySIM app written by gray forges the token in the baseband, which will trick 3.9BL but not 4.6BL. With a neutered phone, the integrity check is skipped completely. So now you can run recent firmware releases with a 4.6BL even if you've unlocked your baseband!
A neutered bootloader will let you use bbupdater on modified ICE*.fls files, so now you don't even need a separate app to unlock. As discussed on the simple_unlock page, you can now unlock the baseband before it even gets put on your iPhone!
Bootloader Version
If you found yourself downgraded to 3.9BL (without your consent) by running buggy software, the iPhone Dev Team comes to the rescue. With BootNeuter you can freely go back and forth between bootloader versions. Now you can truly restore your iPhone to its out-of-box condition.
Fakeblank
For iPhone hackers who want to be able to run serial payloads directly at S-Gold reboot time, BootNeuter lets you choose a fakeblank bootloader. If BootNeuter detects that your iPhone is currently fakeblanked, it will do all of its bootloader operations via serial payload and won't need to erase/reprogram the baseband to make bootloader changes.
