If you’re using RedSn0w as a tethered jailbreak solution for your iPhone, then you undoubtedly try to avoid rebooting your iPhone whenever possible. That’s because, as we’ve previously discussed, a tethered jailbreak requires a computer in order to reboot your iPhone successfully.

This “tethered boot” is accomplished by means of RedSn0w, and the Dev Team has tried to make it as painless as possible with new solutions like ‘one click’ support. However, if you still find that the tethered boot process is consuming a lot of your time, you may want to try leaving RedSn0w running on your computer indefinitely…

Step 1: After you perform a tethered boot, simply avoid clicking the “Finish” button on RedSn0w.

Step 2: When you need to perform another tethered boot, plug your iPhone into your computer, power off your iPhone, and click “Back” on RedSn0w. You should now see a screen that has “Just boot tethered right now” selected. Click “Next”.

Step 3: Now, you’ll find yourself back at the DFU Mode screen. From here, click “Next” and follow the prompts to put your iPhone into DFU mode. After that, your iPhone should boot back up as normal.

By using this method, you save time by eliminating the need to load the IPSW firmware, as it has already been previously loaded. As long as you don’t click “Finish” at the end of the process, you can repeat this over and over as many times as needed.

If you rarely turn off your computer, this is one of the quickest ways to perform a tethered boot on your iPhone.

  • binky73

    so did you use limera1n to jailbreak 4.2.1 on 4 & 3gs using an older version of limera1n, because there isn’t a version of limera1n for 4.2.1 yet, right guys?

  • stfudvs

    redsn0w uses same exploit used by geohotz in limera1n, it’s still tethered. Akbar is wrong

  • AkiraTakashi

    So Limera1n works good on the iPhone 4 using 4.2.1?? someone clear this up for me cuz Im ready to get off 4.1

  • AkiraTakashi

    and I dont care to be tethered… I aint got that to do lol

    • Ernesto Castellanos

      No. Don’t try it.

  • Alex

    @Akbar

    There’s this thing for the iPhone (it’s fairly new), I believe it’s called “firmware”.

    Apparently there are different “iPhone firmwares” and each one requires a new or updated jailbreak due to Apple making the iPhone people’s exploit go away. (For the normal people reading, Apple patches the exploit and therefore a new one has to be discovered. Each new exploit is what allows us to run the unsigned code that we call jailbreaking.)

    Back to @Akbar
    Not knowing is one thing, spamming, trolling and arguing is GTFO.

  • YOU GTFUOFF ALEX, You are RETARDED ..
    I dont know about ur term and languages about jailbreak .. But i have an iPhone 4.2.1 and i m using limera1n to jailbreak my iphone 4 as well as iPhone 3gs.. I REPEAT, i have iPhone 4 and iPhone 3GS with 4.2.1 FIRMWARE. OR IPSW, Ive jailbreaked it with LIMERA1N and it works perfect for me.
    YOU CANNOT UNLOCK, AS IVE SAID THAT BEFORE.
    So if u believe ur the shit and u know nothing, than its u need to GTFO from here ..
    Thanks ..

      Akbar…

      If you have your phone jailbroken with 4.2.1 do us a favour, yeah? Turn your phone off and then turn it back on, then post a reply here. Your silence will be the answer we all want.

  • djjosse

    Or a better thing, post a video when you do it
    So you can show us newbies the good stuff 😉

  • Icegirl79

    limera1n doesn’t work on 4.2.1? dose it????

  • Alex

    I have a feeling it’s just a troll.

  • Guys what about downgrading to 4.1 I think no need for redsn0w to boot your 3GS.

    If I remember right one of the 3gs downgraded for me even without sh blob saved

  • ndru

    Akbar is quiet now. Haha

  • Uglatto

    Guys if you have any questions on the iPhone go to the dev team web sight or try musclenerd’s twitter page.

  • Simon

    Lol @ Akbar. Perhaps he is that ventriloquist doll Akbar the Terrorist! 🙂

    More likely this idiot has an old bootrom 3G phone and thinks it’s an iphone4 :))

    You got to laugh at these clowns sometimes!

  • Mur79

    To all of you guys.
    What about untethered boot of 3GS ( 4.2.1 and bb 6.15)
    I am tired of tethered booting.
