    Hi,
    Wonderful post. I wanted to ask one thing, that once the phone is rooted, if a rom has been installed with some custom recovery e.g. CWM recovery, so now when unrooting the phone, should the custom recovery also be removed and the official recovery to be installed again??

    Thanks,
    Omer

    I think we should not your software with Pit file. PIT file for for partition. I onced flashed my phone with pit file and 16 gb internal memory become 4 gb. and if I would have flashed my phone at that momomt with any other rom , then my phone might have been hard bricked.

    Pit file is not recommend at all.

    • sohil memon says

      Bro If you want to delete old partition and data created by Custom ROM and root apps then you must select “.pit” file.

      • Sumz says

        No it does not. Hence I followed the following

        Installed stock ROM rooted using Odin
        Installed Triangle Away app
        Ran Triangle Away and set counter as NO (the default)
        Un installed Triangle Away
        Cleared root from the stock for good

        What I am left with is Stock ROM Unrooted and Counter set to Zero or No (as default)

    • sohil memon says

      Ofcourse it will erase every thing and you will feel like a new phone you have got!

    hi man :)
    when i down load the firmware file i found only the .tar.md5 file along with the ss_DL.dll file
    i couldnt find the modem / csc / pit files :(
    please help i need to get this done … and is there any other way to clear my counter to 0 rather than triangle away app ?

      • shahzad says

        I was also missing modem and CSC files and after ready this reply I CAREFULLY read your post again but couldn’t find “if you don’t find modem…..” :)

        In some reply to someone, you have also mentioned that using PIT is necessary if rooting has done something with partitions. But in this reply you are saying “it’s OK”. Is this really OK?

  4. Vardhan says

    I just want to know that if i have a custom rom installed then should i first remove the rom and do this or this will remove the traces of custom rom as well as restore the firmware?

  9. Akhil Gupta says

    Hi,
    I followed ur process to unroot my Note 2 N7100XXDMC3 . I have also tried different roms from different places and seen and followed the steps on youtube (which are exactly the same as what u have mentioned).
    I successfully get the stock rom installed and also the stock recovery comes up.
    No matter how many times i try it (having it successfully installed) my phone does not register any Sim inserted and i cannot use my network.
    The phone recognizes the sim but does not register it n i get a msg “Not Registered on Network” everytime i try to make a call.
    I m new to these things but a fast learner.
    Kindly help me with this.
    I really wanna get the phone unrooted.
    N yes the Counter on my phone does not change to 0 nor NO.
    If u want i can record a video and maybe compress it n send it to u.
    I believe there is nothing wrong im doing but nothings helping me here.
    have been trying this for over a week now..Kindly help.
    Thanks in advance.

  11. Sharaf says

    i already install this firmware NZC-N7100XXDMF3-20130730101607 but no network Emegency call only what to do?

  12. J Kilgren says

    Thanks for all the info! I do have a problem though I got what I believed to be the correct firmware ( I have the galaxy n2 I605 verizon). When I get odin up the ID:COM goes yellow and I only have the MD5 file and PIT file. I enter those two and have auto reboot, F. reset time, and Re-Partition checked as I saw you said to do. It tells me the MD5 hash value is invalid and ends. Did I just get the wrong firmware file?

  13. J Kilgren says

    Also just wanted to let you know that the problem I am having is that I rooted my phone, then attempted to unroot but the recovery is still not stock and I cant take any updates. When I put my phone into download mode it does say odin mode and custom binary: no and current binary is Samsung official. Is this what I need to do? As there is only one stock firmware for my phone and its the one that is telling me the MD5 is invalid. Sorry to keep hitting you with questions!

  14. J Kilgren says

    alright I got it to pass in odin but now im stuck in a bootloop and it seems i cant access the recovery (volume up+power+home) only download mode (volume down+power+homescreen) what now? lol

    • sohil memon says

      Bro first you tell me which firmware version you have download? And for the bootloop. Take out or battery for 30 sec. and re-insert it back!

      Do this:

      1. Switch off the phone completely
      2. Press and hold “Volume Up + Power Button” for few seconds.
      3. Now you will be into Stock Recovery mode seeing some “4 – 5 options”. You can use volume buttons to navigate and power button to select.
      4. Now, navigate to “factory data reset” and click ok.
      5. Now, select Wipe Cache Partition and click “OK”
      6. Reboot you device.
      And you are done

  16. Patrick says

    I can’t seem to find the “modem” file ,the “CSC” file and the . pit file when using odin to browse my stock firmware folder I have a galaxy note 2 in the “BMC” region.

  17. says

    I’ve got an N7100. Think my phone’s bricked. Started about a week ago, would freeze most of the time so i’d have to restart. Had this ROM at the time – GT-N7100_WanamLite.UBDMC1.V3.4.NO-WIPE. Figured maybe the issue is with the ROM so i flashed a Paranoid Android ROM on but it would still freeze and stuff. One day i answer a call and the thing freezes. I switch it off and on but its stuck on the “Samsung Galaxy Note 2 N7100″ bootup screen. Not sure what to do now…need help. Please.
