Ok say i have kitkat 4.4.4 and cannot update to lolipop via System Update because my root was messed up due to earlier update. I want to know if i can update to lolipop using Odin and obtain a root for it. i am on stock kernel now with root and i was wondering if it will work before i flash back to 4.4.
If you use odin to flash you will loose root and any custom recovery you have installed so you will have to reroot etc after upgrade.

Can we get OTA updates through custom recovery in such a method?
Get OTA files from an unrooted S5 when it's ready to OTA and flash it to a rooted S5 through the custom recovery?
Is there a way to get the OTA files?
I have a rooted S5 and I just used Kies and it installed the update with no data loss for me ******still back it up***** Then I just reinstalled a custom recovery and SuperSU binaries to root.
I think you cant since stock rom OTA needs a stock recovery
Not only a stock recovery but also unrooting the phone.
Samsung OTA must do a rom check is quite annoying, while Huawei's OTA does not check whether you rom is modified but the files to be updated.
I am on 5.0.1 rooted with stock ROM and stock kernel. I recently got 5.1 upgrade notification.
After downloading the data and restarting the phone, it started installing updates and after a while it showed "error" and stopped.
Now I m on 5.0.1 with no 5.1 upgrade notice.
What is wrong and what should I do for this?
Thank you.
Do I need to unroot? I am on stock kernel and ROM.

Yes, you need to unroot before you can apply the OTA upgrade. Look for the Nexus Root Toolkit, and it should be able to clean up for you.
But prior I didn't need to unroot to upgrade anytime! To upgrade JB to KK or KK to LP, I didn't unroot before installation.
you need stock recovery to update via OTA
Yeah I was on pure stock. Stock ROM kernel and recovery.
Btw, I unrooted my phone with simply unroot and then OTA update went well.
So now I am on stock 5.1 unrooted.
Thank u all.
i have troubles as well. i unrooted, installed stock recovery (via n4 toolkit) and tryed to install. it takes longer then before but i stell get an error. SuperSU is gone in my app drawer.. any other help?
PS: i am on stock rom 5.0.1
i tryed to use sideload ADB update. it says: "/system/bin/app_process32" has unexpected contents. Error in sideload/package.zip. Status 7
any tipps?
im on 4.4.4 NK2. from what I gather, best way to go is root from what im on now and not take the lollipop update. just want to make sure that is correct and that this is correct way....
1. Flash The NCG stock kernel via Odin
2. Reboot & Root using Towelroot
3. Install SuperSU, open the app and allow it to update binaries normally
4. Flash NK2 kernel via ODIN
after that, is the newest lollipop update worth taking? i heard there was problems.
also, i see that there is FlashFire beta....i know its basically mobile odin....is safestarp still necessary to flash roms or can i flash them via FlashFire?
thanks in advance!

Looks like you have it right. If your phone is new to you you might consider flashing the full wipe NGC tar file and starting from scratch. Good way to get rid of any junk that might be on your phone.
You can flash with flashfire and go up and down and keep root easily and without using odin. In my opinion, it's still good to have safestrap. It is the only recovery available to you. I still run 4.4.4 on my S5 though I haven't tried the very latest lollipop that came out. I'm fine running RicksRom.
Hello
Last night, I accidentally pressed OTA update button, so my phone got upgraded to NK7 from NK2.
When I had NK2, I followed this thread http://forum.xda-developers.com/showthread.php?t=2784880 to have root on NK2 before.
Now I have NK7, lost root, still KitKat 4.4.4(not lollipop), but have no idea how to downgrade back to NK2 w/ root or keep NK7 w/ root.
So, my question is,
How do I get back to NK2 w/ root OR keep NK7 w/ root?
I don't want to lose my data on my phone.
Is there any way to do this without flashing it back to stock NK2?
Thank you in advance.
Install towelroot and supersu first. Then, flash the NCG kernel. When you reboot, ignore the force closing apps and run towelroot. Then run supersu and let it install itself and disable knox. Reboot, flash NK7 kernel.
If you are using kitkat, please use safestrap and spare yourself the trouble.
Also on nk7. Really no desire to go to Lollipop just to enable wifi tether.
Is there a link to safe sources of the kernals needed?
i was able to take part one of the update which i think did something to Root....when I open SuperSU it says cant install binary, may need to re-root. I don't want root anymore. I tried second OTA update and fails.
I'm guessing i just have to odin flash a stock img?...my question is, can i do the lollipop one? or do i have to do kitkat and just take the OTA? also, does it matter which version of kitkat or lollipop?
thanks!
download the latest stock rom from somewhere, and flash with odin or flashfire. That should be all you need to do.
thanks...just flashed one of the lollipops and worked great! didnt have to even kept data and custom went away!
