[Q] System update question? - Galaxy S 4 Q&A, Help & Troubleshooting

I just downloaded a custom ROM to my Galaxy's s4, and I like it, however my phone says I have a system update. I was wandering if I should update it even though I'm using a custom ROM or not? I'm afraid it might mess my phone if I update it.

[Q] zune update prompt

hi guys im still using my good old 7 trophy,
Now recently i plugged my phone into my laptop and i got a prompt from Zune that there is a update available ( im using dynamics ROM 2.0 )
The update its prompting me with is - 7.10.8860.142,
Now i think i know the answer to my question but here goes,
If i update will i lose my ability to use custom apps ect will it lock down the rom again and stop me from doing things i could with my current custom ROM ?
Also is there a updated custom ROM available with the fixes/tweaks from the 7.10.8860.142 update ?
Essentially i dont want to lose any thing like my custom apps ect.

[Q] Update after rooting

Dear gurus,
I'm new to Galaxy family, I have a small question. Provided that I have root access for S5 and using Stock ROM. Am I still able to OTA/Kies update?
The reason I want to root is to get rid of SamSung bloatwares and use custom kernel.
Thanks
No. You have to download firmware/rom updates then flash them to your phone now.
Using the phone for updates after rooting will cause you to lose all root access and then would just cause more problems. As stated before, you'll have to manually apply them once rooted.
Tks you all, I got it!

How to upgrade after root

HI.
I really liked the idea of keeping pretty stock (ie no custom rom).. but just tweaking with root / xposed etc.
But.. doing that I now cant install firmware upgrades...
Is it possible to remove root so that ota firmware upgrades work? Have no idea as in the past I've just had custom roms..
Thanks!

One of the mods will probably move this to Q&A as its where you should be asking this question.
Anyways if your sticking with stock and rooted but want to update the firmware as they come out you simply get it via a full firmware flash from Samsung's own Kies 3 software.
Doing this however breaks your root and any apps/mods that you've installed to the system partition however you can simply just re-root and reinstall any system apps/mods you happened to have installed there.
This is not a big deal and is generally quick and painless.
Also remember that if you use a custom recovery TWRP or CWM doing a full firmware flash will restore the stock recovery and you will half to re-flash that back as well.
You wont get notifications about updates however since your rooted and OTA gone. Just keep an eye on things for your specific device and region for updates. People generally post here on XDA about the new updates when their available as well as firmware update news from Sammobile.com
You can also plug your phone into your computer with Kies3 running and it will check to see if your on the latest firmware available as a way of manually checking.
II had the same doubt. Thank you for the clear explanation.

[Q] Dumb question: Will OTA update break my phone?

Hi all,
I did search before posting this, but couldn't find quite the question/answer I was looking for. I've got a rooted S4 SPH-L720.
I've got a custom ROM installed, Sacs 4.3, and the phone has been fine. I just got the system update downloaded and the button to install it. I've got TWRP as my recovery right now.
Last time I had one of these I just turned off notifications, but wasn't sure if this is an important update, or what it even updates? Is it only for phones running Stock?
Thanks,
-Jeff

Can I update my unlocked, rooted phone to new L720VPSGPL1 software?

Hey guys,
Want to wipe my phone fresh since I'm running out of space. My phone has been telling me for months that I have an update, but I haven't updated because I've been told on here never to do OTA updates.
I tried looking around for a stock rooted ROM for this like I've flashed for other versions, but I can't much if any info on the new PL1 update. Usually, someone posts a de-knoxed, rooted version of the software. Is that around or what should I do?
How should I do the update? If I download it from sammobile and flashed it, will that screw up my phone?
Edit: TBH, it's been a while since I've done this and have forgotten the right terminology. I'm not sure if my phone is "unlocked," but I have Philz Touch recovery on it, definitely rooted, and whatever else is built into those modified stock ROMs. Just want to wipe, update, and keep my functionality without bricking or something, since I need this thing working. I can't seem to find a straightforward post on here, and I'm just so busy with school I feel like I can't catch up and relearn all this stuff again.
Thanks for the help
