    I successfully (?) followed the upgrade to the letter and I did get a 5.0 Lollipop rooted phone. I used it for awhile but realized my phone was slower and many of the automatic functions, like auto rotate of the phone and turning off the screen when I was using the phone no longer worked. I was forever making pocket calls to people, etc. Very un-nerving.

    So i used the first part of the process to down grade my 5.0 Lollipop back to 4.4.2 KitKat. I originally had 4.4.4 but since I didn’t that I could root that I used the 4.4.2 version. All went fine and my phone is now back to the normal phone I had before I started except that it is rooted. :)

    Thanks for the information. It worked for me.

  2. i completed all the steps but in the end when i tried to flash the zip file using safestrap the error comes out “error executing updater binary in zip…..”. i couldn’t complete the process and failed message comes out.
    is there anyway you can help me ? i have samsung galaxy SM-N900 A (AT&T-USA)

  3. works v.fine and good for N900A model, i checked many blogs and links but this is best of all of them, works very smoothly and easily…
    Highly recommended… (Y)

  4. ohh Thanks man… It goes very fine…
    so easy to root lollipop…

  5. Can someone help! I downgraded from 5.0 but safestrap will not boot. pleases help.

  6. Constantly get “Unfortunately, the process com.google.process.gapps has stopped” click ok and comes right back. Reinstalled lollipop from zip, worked for about 5 minutes. Than the same thing.

    • Did you try to clear cache and data?

      • It has been running good now. Thanks!

      • Can someone help! I downgraded from 5.0 but safestrap will not boot. pleases help.

      • Hi all, just bn thnkng, is it possible to flash UK Firmware for N9005, on N900A running android Lollipop [OC1]. If so, please help me with the links , because I think these phones are identical and they can handle the same firmwares, and am willing to risk bricking my N900A, to try this. Anyone who can share the N9005XXUGBOE9…..with bootloader, pit and csc files, I would like to try it out and see what happens

    • Just to add I noticed the phone asks to update google play services. When you click update and restart the phone you get this ( Android is upgrading optimizing app 1 of 1) That’s when it all starts with the com.google.process.gapps has stopped B.S.) I cleared data for google play services and the problem stopped. However it does not let the gmail app run without the update. And every google app you run asks to update google play services. So I tried upgrading google play services again, restarted phone it did this again (Android is upgrading optimizing app 1 of 1) But so far so good. Ill give it a little while see if it starts acting up again.

      Hi,

      I’ve got the same situation. Have you found the solution yet?

        That worked for me.

  7. Worked like a charm thanks!

  8. Is this deodexed or odexed?

  9. My phone starts then says gn3.. then goes blank, the goes into recovery booting, and its just a cycle… and seafestrap is still there, please help!!

  10. Will there be any updates for this? there are a few bugs..

  11. Is this 5.0, 5.0.1 or 5.0.2? I heard of memory leak causing battery drain. Is this the case with this ROM?

  12. 1, 2 ,3 .and done , and its working smoothly.

  13. high five , nice work dude , thanks for the guide

  14. Worked great for me.had to wait a long time to get past att splash screen .was getting worried but waited and viola lollipo.thanks for the nice write up

  15. This does not work for me either on mine or my partners N900A, done it twice to the letter on both phones. ..and I root and flash stuff lots.

  16. I follow the instructions but I seem to be stuck in a loop. I just see the Samsung Galaxy Note 3 splash screen and after 30 seconds or so it vibrates and reboots.

    • Okay I just did a recovery reboot and wipe. Everything came back up on 5.0 but I am getting knox stopped working messages so I will just disable that I guess as indicated below. Otherwise, thanks for the tutorial!

  17. I have follow the intructions of the Case 2 and everything works fine. Just some issues with the Google Apps but just download the update at the Play store a ready.

  18. Thanks. Updated . Everythink ok except ,” knox counter unfortunately stopped” message during the restart.

  19. WHAT RECOVERY APK DO YOU NEED ONCE YOU CHANGE TO LOLIPOP SINCE YOU MENTIONED THAT SAFESTRAP WON’T WORK ANYMORE ONCE YOU CHANGE TO LOLIPOP?

    • All steps on NC2 Android 4.4.2 KitKat not Lollipop
      The last steps of this guide is to install Lollipop, so after rebooting your device Safestarp won’t work.

    • Im not 100% sure that safetrap does not work. Ive read somewhere and I didn’t want to try. You could lose the stock recovery. Do some research about safetrap I might be wrong, but stock recovery works fine.

    • It is possible to have Safestrap after you install Lollipop.

      How to Access Safestrap Recovery
      Since Safestrap Recovery does not support Lollipop officially, here is a workaround to access it after updating your AT&T Note 3 using the Safestrap method from above.

      Long press the the Power button to bring up Power Menu.
      Select Safestrap Recovery from the Reboot Menu.
      Now you can use Safestrap for purposes like backing up, restoring and flashing ROMs.
      When you are done with using Safestrap, return to main menu and tap the Install option.
      Navigate to /sdcard/OC1_Kernel/, select SM-N900A_OC1_Kernel_Safestrap_Installer.zip and flash this file.
      Having flashed the file, you can exit Safestrap by selecting Reboot> System option.

  20. I am going to wait for a few days seeing as people are having issues with the installation and it looks like it has to do with the roms.

    • I’ve followed these steps and it works. The phone from for 10 min on att logo but be patient. It will go through. I haven’t checked if safetrap works or not. I read somewhere thatsafetrap does not work, so did you on want to try. I might lose the ability to boot into recovery. Xposed doesn’t work either.
