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?
FlashFire doesnt open for me; the screen goes white momentarily and then it disappears.
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.
i want to try this im on kit kat and the links b with my i545 both gave me corrupted files. any suggestions?
The mirror is working
I’m going to try but do you think after I updated i will able to do those steps on this forum http://www.zidroid.com/how-to-update-keep-root-verizon-galaxy-s4-on-lollipop-oc1/
I’m so desperate lol 🙂
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
Unfortunately there isn’t root for Verizon Galaxy S4 on Lollipop
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.
Same Here… Stuck at Samsung Screen
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.
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
The link for the .zip file to revert back to NC5 doesn’t work. Can anyone help to get back to NC5?
It is working, please try again
No… When I try to flash the .zip file in the PDA slot, it always fails during the boot.img process. Is there any way to fix it so it will work?
I’m sorry I thought you was meaning download link isn’t working
Did you update your devcie to lollipop using this tutorial or via OTA/Odin3/Kies?
I updated via this tutorial.
Could you try this one https://www.androidfilehost.com/?fid=23991606952596370 or https://www.androidfilehost.com/?fid=23501681358539677
OK so I needed to use my phone so I went to the firmware. Is there a way to go back now?
Try flashing the firmware
When I flash the NC5 firmware, Odin says that it fails. Is there a workaround?
It fails during the “boot” or “aboot”?
It fails during the boot part
Is it at all possible to go back to NC5?
thanks… thanks…thanks… thanks… thanks… thanks… thanks… thanks… thanks… thanks… thanks… thanks… thanks… thanks…
Worked great, looks good so far, thank you so much!!
Both if the rooted stock ROM links lead to nothing…
The mirror is working, please try again
Both of the rooted stock ROM links lead to nothing…
I did this and it worked perfectly BUT!… I cannot access recovery mode. Download mode is fine. What did I do or is this normal? How do I fix it?
Try to boot into recovery via How to Boot into Download, Recovery Mode Using ADB cmd
So I tried your suggestion but couldn’t get it to work. Running xp. I took a suggestion and flashed the stock recovery which worked but now when phone reboots it goes black screen after vzw splash screen. I get services stopped pop ups. Sigh… I just want to go back to a working phone now.
Disregard last comment. I factory restored from recovery and then redid the whole process with flash fire and everything is OK now. Thank you
Worked for me. Thanks!

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?
Yes
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
Man, you’re awesome. It booted up successfully and is now optimizing the apps for Lollipop. Thanks!
You are welcome 😉
followed this exactly… now device is stuck on the first logo..
Downgrade to NC5 > Root via towelroot > follow the instruction again
