  1. Hi Nashi, thanks for pointing that out. I have corrected it in the tutorial. We have to write about so many devices and models that sometimes we get confused about the download and recovery modes.

  2. Thanks a lot for your guide…Just to point out..on GT-P3100 to get into download mode it’s Power + VOL DOWN. Not Volume Up. People are having issues finding themselves into Recovery since the guide says Vol +. Also for me I need to have disconnect the usb cable from computer or power source…while doing so…
    THank you so much for your great guides. Really appreciate. I was lost all over the web since purchasing my tab two weeks ago.

  3. Helo sir , you have given two types of rooting your device …I just want to ask any difference ..does either of the rooting style give better performance than other…im just new to it.. so can u plz tell me …

  4. Thanks dude although i didn’t look at the article 😛 i tried to root again and it worked TYVM

  5. Hey FOA i want to thank you for the great work you always do
    then : just wanted to correct something if you want to go to download mode you have to press the “volume down ” not the volume up
    although i did all the previous steps exactly as you said it says ***FAIL*** on Odin instead of pass what should i do ?
    The Report says : cannot open the serial (COM) port

  6. Hi,

    These options are found under Recovery Mode. You have to boot the tab into Download Mode, pressing: Volume Up+Power combination. Reboot the device and try again.

  7. Hi! I’ve downloaded all the necessary components to root my tab but i’m struggling with how to put it into download mode as I am faced with unfamiliar options to choose from .
    “reboot system now
    apply update from ADB
    apply update from external storage
    wipe data/factory reset
    wipe cache partition
    apply update from cache

    Which one do i choose because ive tried ADB and storage but with no success and scared of bricking my tab if I choose wrong

  8. I told you the way to boot into the CWM Recovery mode. Turn off the device, then Press and hold volume up+power buttons together to enter the custom recovery

  9. the CWM Recovery has already been installed. Press and hold volume up+power buttons together to enter the custom recovery. Let me know what happens.

  10. As long as the flash counter set to Zero, you are out of any problem. You will get all the benefits of OTA that’s the magic of Triangle Away.
    Later by installing the full firmware you can unroot and reclaim the warranty too. Cheers!

  11. sir,
    i ve now successfully rooted my tab and used triangle away to reset my binary counter.
    now the device status is NORMAL and binary counts–>NO(0) and binary–>SAMSUNG OFFICIAL.
    now when i tried to go the software update option in the settings menu, it tried to connect to internet to updates if any.(obviously, as ts the latest version, so it wrote a message after some time(2 mins) that my device has the latest software.

    now does it mean that even though being ROOTED i ve the authority to take updates via OTA and KIES and also take backup via KIES???? this is v important to me.
    dunno y, kies somehow doesn’t show upgrade firwire option in my PC even when my device was NOT ROOTED.

    also one important ques—–>i ve the full firmwire worth some 780 MB, so ll flashing this ROM again(it didnt increase my binary count, when i tried to upgrade manually via ODIN) via ODIN remove my root, as its very important as i ve to do it in case of any major problems to AVAIL MY WARRANTY???

    please sir…….

  12. sir,
    as per my previous problem discussed in this page—> upon upgrading the firmwire version 4.1.2 manually using ODIN, i ve successfully changed my DEVICE STATUS from CUSTOM to NORMAL, which mean that now on i am allowed to recieve future updates,(as device is not mentioned as modified or custom) and in the download mode my BINARY STATUS shows me SAMSUNG OFFICIAL, which means no problem and i am under warrantee.

    but still the problem is that I MAY VE LOST MY WARRANTEE EVEN THOUGH MY PHONE IS “UNROOTED” cz once i tried to root my version of 4.1.1 with some verison of .zip file specifically for p3100(my device), but it failed as it showed me the message “VERIFICATION SIGNATURE FAILED”. i tried it again freshly, again the same. the only problem was my device status was “CUSTOM” with binary count 2.

    upon upgrading with this firmwire, my device status stated back to normal, with binary status–>OFFICIAL SAMSUNG. now the only thing which makes me lose my warranty is the BINARY COUNT which is stucked at 2(it should be 3, as i ve flashed manually using ODIN with this firmwire).
    i dnt want to lose warranty,, so how to reset this binary count WITHOUT USING “TRIANGLE AWAY” as for using triangle away i ve 2 root my device which again makes my device lose warranty.
    🙁 🙁
    pleazse help sir

  13. Rooting has nothing to with data connection. It might be some other temporary reason. Try rebooting the Tab or wait for some time. It might be a network error or something like that.
