  • Fix Battery Drain with redsn0w 0.9.6b6 and SAM


    The iPhone Dev-Team has released redsn0w 0.9.6b6 for Windows and Mac with a new tweak that avoids the issues like battery-drain and overheating that plague unlocks. Rather than using redsn0w to hacktivate, this version lets users click a "Deactivate" button to remove the patches that affected battery life and push notifications, allowing @sbinger's SAM tool to do the hacktivation.

    Sam (@sbinger) Binger, the developer of TetherMe, came up with what he calls Subscriber Artificial Module (SAM), which tricks iTunes and your iPhone into generating official activation tickets even though the unlocked device carries an unofficial SIM. As a result, the lockdownd patches that were required to make hacktivation work with redsn0w are no longer needed, and unlockers can use SAM to hacktivate without taking the battery life hit.

    The Dev-Team is making the process easier by adding a "Deactivate" button, which removes the patches and lets SAM take over the hacktivation process. SAM also includes a "stockify" tool to let users of iOS 3.0+ to revert to a stock lockdownd: add http://repo.bingner.com as a repo in Cydia, install "SAM" and "SAMPrefs," and then run stockify in secure shell.

      will hacktivate your device. after the phone has rebooted you will
      see you still have all your programs from cydia and itunes still on your device and it will sync your device, hope this helps bacause it helped me when I was in the same position oh also open SAM and it will say factory unlocked , so no wildcard message. I just turn off data and set mail to fetch also location services off when I'm not using these and battery is acting like it should good luck
      what i did after is simply run latest redsn0w again with none of the option checked, iphone hacktivated again..but the battery problem is severe, man. charging like every 3 hours. I hope there will be a fix on SAM later on. or maybe a more thorough instruction just in case the fault is on me.

      I have a new iphone 4 32gb on 4.1 /2.10 that I received as a gift from my brother. I am trying to activate it through itunes but they are asking for my brothers social and zip, but I cant do that because he cant have his 3gs be turned off.Can I jailbreak and run sam to get past the activation issues Im having?? And then use it with another AT&t account?

      Okay I have a Question now.

      1) I got an iPhone 3G[S] NEW BootROM on 4.1 - Jailbroken (sn0wbreeze) and Unlocked (ultrasn0w).
      2) PushDoctor installed and YouTube & Push notifications work fine.
      3) I don't experience a battery drain or connection loss.
      4) Also when I installed SAM & SAMPrefs, it shows the Activation State as : "FactoryActivated".
      5) I've Hacktivated through sn0wbreeze though.
      6) My Carrier has launched iPhone 3G[S] Officially in my country only for Postpaid customers. But I didn't buy my iPhone through them and I'm using their Prepaid SIM.
      7) So my Question is, Should I use SAM and SAMPrefs and Will installing it improve my battery & overall Performance any further than it is now?

      Yeah, this SAM thing is only for those who have "upgraded" to 4.2 and are using the tethered jailbreak.

      It is actually for the people who updated their baseband to 6.15.00 and hacktivated.

      Uh-oh - that's good to know. Does that mean that downgrading to 4.l won't help me with the battery issue, since I'm stuck with 6.15.00 regardless?

      Hactivation .vs. Activation. Nothing to do with tethered/untethered.

      Ya, you will probably still see the issues on 4.1 if you hacktivate

      I'm already unlocked, but it was by greenpo1son and not redsn0w. Will this still work for me or do I have to restore and unlock using redsn0w? I'm on firmware 4.1, does it even apply to me? Everyone is so confusing.

      I assume they're working on one. Meanwhile I just downgraded to 4.1 to get rid of the hassle of booting tethered.

      This new Cydia feature is
      applicable to my iDevice ?
      No, you are not affected since you used ur atnt to activate

      Option #2: my custom stockify program - works on any phone 3.0+
      With SAM and SAMPrefs installed; install openssh and secure shell into your phone. Run "stockify" and it will revert your lockdownd to a stock lockdownd
      Reboot your phone
      What the heck is 'Stockify' can't seem to find it anywhere... Can some one enlighten me?

      See my post elsewhere in this thread for a link to better instructions.

      Now that I finally got this working, the difference is like night and day. It took a while, but it's worth it.
