    is it possible to make custom firmware 5.0.1 without cydia ?
    I don't need the Tethered jailbreak just need to preserve baseband

    You never use Cydia to MAKE a custom IPSW; either use redsn0w (5.0.1), sn0wbreeze (5.0.1) or pwnagetool (4.x)if you want to make one that preserves your baseband.
    Go to for detailed instructions... ;)

    you didn't get the point
    I don't need the jailbreak
    just want to preserves my baseband
    any idea ?
    sn0wbreeze already jailbroken on custom firmware
    pwnagetool doesn't support 5.0.1
    and about custom firmware redsn0w I don't know
    any one triad make custom firmware via redsn0w?so after restoring with custom firmware need to jailbreak it?

    I think you can simply use tinyumbrella to update and it will preserve the baseband.
