1. Create a custom ipsw

2. Unpack it, remove rootfs dmg

3. Decrypt ramdisk (xpwntool), mount it.

4. Edit options.plist on the restore ramdisk:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

5. Unmount and reencrypt the restore ramdisk.

6. Repack the ipsw.

NOTE: It just works with iPod Touch 2G MB and iPhone 3Gs old bootrom
