    • CiscoKydd says:

      To get rid of the yellow triangle, which appears on boot after rooting, use Triangle Away. You can find it at XDA Developers or Google Play.

    2. wi-fi doesn’t work
    3. on your video, it shows some apps under super user, mine doesn’t
    4. i tried to un-root my phone, i was able to get the proper stock kernel. i followed the process shown on your video, but at my command promt i only get as far as

    $

    can you help me so that my phone can be either rooted or non-rooted properly? thanks!

      friend please if I can fix the wifi! tell me how???? as I’m not working and what I need!

    • CiscoKydd says:

      The method I used to root my Epic 4g Touch was to go to RWilco.com and download the stock, rooted Operating System. You can find a link to RWilco.com on XDA-Developers.com
      RWilco’s site has everything Samsung.

  9. James says:

    Hello Max,

    I am having a similar issue to Marco’s above (january 4th).

    I also rooted my Samsung Epic 4G Touch using your method and I am have lost my wifi, multiple of my widgets do not work and my 3G shuts down until I reboot occasionally, and I also can not upload a new Kernel, ROM, or return it back to unrooted without a full “wipe data/factory reset”.

    I have noticed when I get into Andoid System Recovery, I am only running and not the 5.0… that you and others are using (even after I flash the ClockworkMod Recovery it in the ROM Manager).

    When it fails, the prompt states:

    –Installing package…
    Finding update package…
    Opening update package…
    Verifying update package…
    E: failed to verify whole-file signature
    E: signature verification failed.
    Installation Aborted.

    Can you help me so that I can either root or un-root my phone properly?

    Thank you!

    • Drew4G says:

      Same thing going on here but my Wifi is working and that YELLOW TRIANGLE is just an icon telling you that you are on a rooted Phone. Nothing bad, unless it annoys you there’s a way to remove it. (GOOGLE IT)

      Here’s my problem.
      I’m trying to flash any ROM on my SPRINT SGS2 and it always ends up “Aborting Installation”. What am I doing wrong? I’ve followed all the steps but to no avail.
      I’m running:
      I’ve used the ROM MANAGER (reboot into recovery via many versions and still nothing)

  12. Joshua says:

    Hey max,
    I have a rooted epic touch 4g on stock version 2.3.6. All the SGS2′s have annoying and loud shutter and focus sounds. Is there any way to turn them off or just remove them from the Android system? I’ve seen forums on the for the same problem but I think they’re for original Samsung galaxy s II. I’ve been on this problem for Weeks and can’t get it.

  15. evan says:

    After rooting my phone, the Search hard key no longer works. That was the button I used as “enter” when in the clockwork mod tool. It doesn’t allow me to select anything. Any ideas?

    New to “ROOTING” but like to learn new things always;) my ? Is can one root sgs2 epic 4g (sprint) to use t-mobile, verison, or maybe at&t? Please let me know ty!!

    • admin says:

      Epic 4G Touch can only be used on Sprint. There may be ways to flash to bootmobile but definitely never Tmobile or ATT.

  32. Lionheart says:

    Oh, sph-710 GB….thankx for ur response.

  33. Ross says:

    Can you give instructions on how to flash ROMS using Odin Mobile? I’d like to flash Paranoid ANdroid but I’m very confused by all of the instructions.

    ODIN Mobile apparently requires tar or tar.md5 files for rooting. There isn’t a Paranoid Android archive in that format. It’s only available in .zip.

  34. Ricardo Barrera says:

    What i can do…

    Regrets…

    • perris says:

      it’s the hardware not the software that prevents otg on the epic touch, sprint had nothing to do with disabling it, samsung blew it by putting in the wrong port

    Max,
    Help! I have a Samsung Epic 4g Touch on Virgin Mobile. Is it possible to install Kit Kat on my phone. It was made in 2013 & came with stock Android 4.1.2. Also, is it possible to get the Kit Kat ROM as a tar file for Odin install? I can’t find it anywhere! If not Kit Kat what is the latest, fully working ROM I can install on my E4GT? I try to follow you as mu h as possible but you’re all over the place! Thanks for all of your great work!

    I am very happy that I caje across this during my hunt for something oncerning this.
