  1. In your post it shows wipe then flash needs to be at the beginning and on the Xda forum they don’t change the default which shows wipe at the end? Which is correct?

  2. FlashFire doesnt open for me; the screen goes white momentarily and then it disappears.

  3. Hello brother, I have verizon s4 rooted and unlocked phone but still it says your device is up to date and I don’t receive lollipop update. Please tell me the solution.

  4. i want to try this im on kit kat and the links b with my i545 both gave me corrupted files. any suggestions?

  5. How to root my Verizon Galaxy s4 SCH-1545 lollipop 5.0.1, i updated to How to root my Verizon Galaxy s4 SCH-1545 lollipop 5.0.1, now i can’t downgrade and i have a problem sending sms any help thanks

  6. Didn’t work for me. I tried this and another guide, and every time I get stuck at the Samsung screen or the screen stays blank with the blue LED. Only flashing back to NC5 through Odin will make the phone usable.

  7. The FlashFire app shows up as malware by AVG. Seems a little too difficult to get to for a widely used app, no such problems with towelroot, etc.
    Also, the download for the Lollipop ROM seems suspicious, no download location is specified, downloading to a cloud location, I guess.
    Would like to use it, but so far, the necessary items are setting off a lot of alarm bells.

    • It’s up to you but FlashFire is developed by chainfire (developer of supersu, auto root, triangle away, mobile odin) he is a developer you trust.
      Download link for the Lollipop ROM is working (check the mirror)

      • I’m downloading this stuff to my PC cause trying it on my phone brought up a ton of popups/redirects, etc., and the ROM download didn’t work at all. The ROM DL was something I hadn’t seen before, but it made it onto my HD.
        Needless to say, anything that smacks of an exploit sets off AVG, but the virus it named didn’t show up on any Google searches. So off we go. Pardon my paranoia, but you can’t be too careful, these days.
        Thanks, will let you know how it works out.

  8. thanks thanks thanks
    but one problem it got stuck at the verizon screen for about 30 mins and i removed the battery and reinserted and it worked . thanks once again

    Looks like it’s failing on the boot.img part. Any ideas?? I’m finding it hard to believe nobody has found an exploit for andriod 5.0.1 yet as there are newer versions out. Please help!

  17. … new link for ROM Please

  18. Hi,

    I just got the update for my Galaxy S4 from Verizon (i545) and took the OTA update to 5.01 lolipop. I am running OC1 and want to root it, how should I do this? You say to not downgrade to NC5 in the article, is there any other way to root?

    Thank you!

  19. With odin and I545_Back_to_NC5.zip odin FAIL…..

  20. The link for the ROM does not work anymore.

    • I’m sorry there isn’t rooting method for Lollipop, if you would like to try flash this to downgrade to NC5, if it doesn’t work flash back Lollipop firmware

      • Thanks but I545VRUFNC5_I545VZWFNC5_I545VRUFNC5_HOME.tar.md5 and odin i can’t , is FAIL!!! Can i downgrade in another mode??

        • Use firmware file that I post in the reply please

          • Odin crash with I545_OC1_Stock_Rooted_ROM_wNK4_BL.tar.md5…….

          • Flash this firmware LINK to downgrade to NC5 (not tested), if your device stuck in bootloop reboot into recovery mode and factory data reset
            If it doesn’t boot after all Odin back to Lollipop firmwareLINK

  23. I haven’t upgraded since the first KitKat update, I’m on 4.4.2 with NC5 bootloader so I don’t have to downgrade. This should work, right?

      • Hmm. I tried this 4 times, and each attempt it gets stuck on either the Samsung animation or the Galaxy S4 logo. I have to reflash the original NC5 rom using Odin. Do you know what might be causing this?

        • Try it again and dismiss step10 and step11, if it doesn’t boot after waiting enough, go to recovery mode and wipe data

  24. followed this exactly… now device is stuck on the first logo..
