  1. Hi,

    I’ve already rooted my Bell 747MVLALH1 S3 but I didn’t use your pre-rooted flash file.
    My counter HAS BEEN tripped.
    I now wish to find a Jelly bean upgrade for my rooted S3. Will i need to use TRIANGLE to bring counter to 0 then un-root ? Or is there a rooted Jelly Bean upgrade out there for my rooted phone? I cannot find any that serve that specific purpose and I do not want to lose root for a jelly bean OTA upgrade.
    Your help would be greatly appreciated.
    Thank you kindly
    Dan

    1. Actually, there are few options to update if you have a rooted phone:
      1. Use a root-keeper apps from Play store that will temporarily removed root. Update your phone via OTA and then again simply apply root.
      2. Use a rooted/deodexed/odexed Jelly Bean stock ROM at XDA-Developer and manually install via CWM/TWRP custom recovery.
      3. Use a pre-rooted stock image from official software update and flash it with Odin.

    2. Hi Neil,

      I tried your solution #1and I temporarily unrooted with Voodoo. Then i forced OTA upgrade. It went into download mode then android fell on it’s back with an exclamation point in it. Luckily, CWM menu allowed me to reboot. It loaded my current ice cream sandwich. 4.0.1 again.
      I then reapplied root and moved on to solution #2

      #2 I searched high and low for a rooted/deodexed/odexed Jelly Bean stock ROM at XDA-Developer BUT i found none that are specific to my i747MVLALH1 S3. I currently run an odexed ROM.

      #3 I cannot find a pre-rooted stock image for my model. Bricking is what i wish to avoid.

      Now i am unsure what to do. One last thing, Voodoo menu specifically says its useless at keeping root using Odin or Kies on a Samsung phone.

      I must be missing a simple solution.

      thanks

  2. i forgot to ask, since my counter is tripped and I am trying to do an OTA upgrade using Voodoo, should I run Triangle first to reset counter? I am guessing my android fell over because Samsung OTA refused install if counter isn’t 0.

    Dan

    1. Chainfire’s “Triangle Away” Binary Flash counter reset can be used either after or before installation as long as you have SuperUser root access.
      If you need to revert back to factory stock, you should do it first before flashing an unrooted stock ROM or applying OTA update because Samsung’s official update wipes root of the device.
