[Q] How to unroot? - Verizon Samsung Galaxy S 4

Decided to trade out my S4 mj7 for an HTC one. Simply can't stand the inability to flash custom recoveries/ROMs/tweaks. That being said I need to unroot my S4 but haven't been able to find a real how to on it. I would greatly appreciate if someone could point me in the right direction to do so. Thank you.

Did you try a full unroot from supersu? Also flashing the latest odin tar should make your phone seem like new.

Truthfully I was unaware that there was a full unroot option in supersu. I'll re-enable the apps I have frozen, remove root apps and try that. Thanks

If you are on sprint and you want to brick your phone then by all means flash whatever you want from here, otherwise go to the sprint forum.

Warning

I have been reading thorough the returning to stock post in lg general Dev. A lot of people are softbricking or bootlooping by flashing OTA an edited recovery.
Before you flash any OTA you must return to stock.
Just a word of warning. If I'm misinformed someone please correct me but that's what I got from reading.

I'm sure anyone that would be looking in the development threads would be looking for development so they might pass over this thread. In turn they will end up 'softbricking' their device because they didn't return to stock before hand.
You should have posted this is the correct place.
Now everyone's phones are going to be messed up.

stuck on recovery
I just stuck on recovery after OTA, now I guess I have to unroot?, what that OTA does anyway? I was looking for more information but there is nothing out yet
Go look at the returning to stock post in general section. There is more instruction there.

if you can get in recovery, you are fine. Just have to clear some files and it will boot fine. It's "soft bricked" because it keeps trying to apply the OTA.
Sprint has an OTA?

If you have a nandroid backup, you should restore it. As soon as you restore it, you should flash back to stock. Then after your phone is clean, take the OTA and then root.

I'm not sure I've just seen lg in general has had updates being pushed.
However if we are on stock rooted ROM, shouldn't we be able to push the OTA? I'm not that versed in this.

Safe thing to do is to always flash back to stock to avoid any issues.
EDIT: Don't quote me on this but according to a Sprint G2 user in the thread below that if you have the stock recovery and didn't flash TWRP, you should be able to take the OTA without having to flash back to stock.

Yeah anyone that's going to be modding phones should get used to not accepting ota updates, luckily it doesn't take long until roms are updated

So will updated Roms include ota data?
Sent from my LG-LS980 using XDA Premium 4 mobile app
Lol I imagine that depends on the rom developer, if not than a rom will eventual get released with the newest software, always a matter of time

So if I'm rooted and on the stock ROM I just accept the OTA and install? Then just re-root?

Yup on stock recovery right now . Gonna hold off tho because I've been reading that someone is making an update we can flash over top with TWRP. I'll just figure out what I want to do once everything is clear and settled. I'd love some better/stronger signal.

Good Info
Thanks for the post. I myself was applying the software downloads for my D800 At&t Variant. I am currently stuck right now and your explanation helps make a little sense of what is happening to my phone. I was stuck at the cm boot animation and tried to do a wipe and restore and a bunch of other stuff and nothing was working. Decided to flash back using the software from that thread, however the flash was listed as successful, but upon getting to the main screen of the os, keyboard doesn't come up, no signal or wifi, then after a minute or two the phone will just reboot. My thoughts are either that I have the OTA software missing key components from the original stock, or my efs is shot, in which case I am concerned. Just got this phone and would love to fix it. I will hunt for original software.
I had done a full lg stock backup through CWM and then exported that to my computer. Would that contain my efs info?
Thanks

Flash 4.1.2 Ruu

My girlfriend has the Verizon S4 4.3..
However she hates it and wants to go back to 4.1.2 or 4.2.... Can I just flash the Ruu file in Odin to go back without any problems?
Thanks for any help!

The tar file for Odin cannot be used to downgrade due to bootloader. Much like the ruu on most HTC phones won't allow a downgrade due to locks in the bootloader.

Yep....your only option would be safestrap and a few roms compatible to run with it.
safestrap enabled, Hyperdrive driven
Or root and clean it up. I did even though I hate stock. TW and Sense are both horrible. VZW and carriers make it worse with the bloat. Root, delay and freeze. I even deleted VZW apk files so I didn't have to worry about them running. I'm on straight talk though, so I wouldn't need them anyway.

Yeah, thanks. She's not very tech savvy and prefers the old look. Smh at locked bootloaders

Bought used, rooted S4. Am I unlocked?

Before I get people in here looking to "flame a noob", please leave me alone if that is your intention. If you genuinely are a helpful person, please read on.
I came from an unlocked s3 before I purchased a phone from Swappa and it is rooted and works fine. However, it has a pink theme and I am not into it. Additionally, I want to upgrade the rom if possible.
The issue is that I don't know if I need safestrap or of it has an unlocked bootloader. The reason why is from what I have read, the mj7 baseband is locked down. However, the phone seems to be running a custom kernel, which from what I have read is not possible on a locked down version. Is it possible that the baseband is just the one used by the custom rom?
Is there a definitive way to know if I can install roms without safestrap?
Thanks for your help!

Install phone info app from play store. If you don't see any reference to mdk...then you have a locked bootloader and can only use safestrap
sent by safestrap powered echo v26
I'm no pro, but I think having that kernel means that you have a mdk phone. I guess you should still check with "samsung phone info" and take a look at the bootloader part. You might be a lucky man
You rock. I installed the app and found this. It seems that I have the MDK bootloader. Perfect.
Thank you!

You are one of us lucky ones. Just a golden rule for MDK users.......NEVER take an OTA update. I recommend vanir ROM if you want to try aosp.

Guys, just wanted to say thanks again. I was able to install Hyperdrive on my S4 with TWRP, just like I used to on my s3. This is awesome. Thanks for everything.

What is the latest firmware version and Android version?

Let me first say sorry for an apparently dumb question. I don't have a Verizon gs4 or a gs4 at all for that matter. I'm trying to help out a few family members that have vzw gs4. They recently got an update and aren't happy with it. Some weird volume issues and the battery getting very hot. I'm trying to find out what the latest update was? Are there many people having issues with it and is it known issues by Verizon......can they expect another update soon to fix the issues etc?
I figured where better to ask than the xda gs4 community.
I'm very familiar with Samsung phones and Android in general. Any info would be greatly appreciated!
Thanks

The latest for a stock S4 is Android 5.0.1 Touchwiz. Firmware/baseband I believe is I545VRUFOC1

I can see where using your phone for business it should be locked down, however, I would gladly pay $50 to have them just unlock the bootloader.
