Removing my custom rom from SM-G930U - Samsung Galaxy S7 Questions and Answers

So i tried to root my phone through a video, I got SuperSU to flash and everything but my phone wasn't "rooted" (according to root checker) and also SuperSU wouldn't update itself. So there goes that, so i decide to factory reset my phone, even though it's brand new, but then i realize i still have the custom bootloader. Well crap, i forgot i already loaded in a custom rom even though it was factory reset. So my question is, how do i get rid of my "root" all together, should i just reinstall the official firmware?

Yes, by installing the stock firmware the "failed root" and the custom bootloader will be gone.

Well, if you restore it via smart switch, then your data will also be lost. But at least you'll have a stock rom.

Hey I have the same exact problem, I downloaded a custom rom, the root failed and it left my phone really buggy and slow and it overheats. I have tried multiple times to flash the stock firmware onto my phone but I have had no luck. Can you explain to me how you were able to get the stock rom back onto your phone step by step? Thanks, this would make my day and as a matter of fact, my next two years cuz I just got this phone in the spring and I'm already having issues but I can't get a new phone for another two years.

What custom rom are you used ?

[Resolved] [Q] I've made a mess of my Nexus S...

Hey guys,
This is my very first post, just to let you all know, so please have some patience! Thanks!
Anyway, so I have a Nexus S 3G (Canada) and I have rooted it, unrooted it, installed roms and everything. I works...for the most part. It's giving me all sorts of different little errors and what not. So I was wondering, how can I COMPLETLY start ALL OVER, as in, factory new, like when you buy a new phone (without the carrier stuff). I wanted to start fresh, fresh out-of-the-oven kind of start, do you understand what I mean? FACTORY FRESH. Thank you all so much in advance!
well download your phone's stock rom and of course unroot it.Regarding the stock bloatware you can modify the custom rom by going in system/app and deleting the apps you dont want to be installed

Thanks for the reply, I've already done that, and I'm still getting errors and other weird things, like not going out of airplane mode, failing to download the OTA 2.3.6 Update (I'm on stock 2.3.1 unrooted, I think), and I don't know if this is normal, but ClockworkMod Recovery is still there. Am I still rooted or something? Plus, when I try to flash a restore, from let's say Gingerbread 2.3.6 Stock, it says MD5 mismatch! How about if it's an ICS AOSP Build, it gives me the normal white Google logo like normal, but then just stays stuck there.
Is the anyway to erase EVERYTHING and start over like NOTHING was ever done to the device? Like when they are first distributing the the device and no one has ever touched it? Is there anyway to do just that?
There is a difference between being "rooted" and using a rooted ROM. You could be using a non-rooted ROM, and your phone can still be "rooted". The first step in rooting a phone is changing SECURITY-ON to SECURITY-OFF. If you REALLY want to go back to when you first got the device, you will need to find a way to turn SECURITY from OFF to ON. When it is off, you are able to access the bootloader, in turn allowing you to install a recovery to install a ROM with rooted permissions. I think the best way to go back to stock would be for you to first download the latest OTA update for your device, do a FULL WIPE of everything on your phone thru recovery (data, system, cache, dalvik cache). Then installing the latest OTA. I do not think however, that this is how you turn your device S-ON.
I hope I've been of some help.

Thanks for your excellent reply, but I have also already done that, EXACTLY that, multiple times too. Dalvik, battery stats, factory reset/delete all user data, wipe cache partition and fix permissions. What else is there left to do?
Thank you all so very much!!!!

[Q] factory reset after one click root

just use the one click root tool by kennethpenn, work perfectly thanks. use titanium back to do a backup of all the app and system then took out all the att bloatware. i have few questions at this point.
1.
will i be able to get OTA updates from att? what will happen to all the bloatware that i deleted? would they appear again?
2.
what happens if i do a factory reset on the phone? would i brick the phone? under normal condition that will erase all apps i installed and return it to factory setting, that means all the att bloatware will be back? will i lost root?
3.
what other things i can do after i root the phone at this point?
thank you for your help
no one can help me with those questions??? anyone???
i am sure a lot of people have the same question.
1.
will i be able to get OTA updates from att? what will happen to all the bloatware that i deleted? would they appear again?
I'm not 100% sure on this, but as long as you're running an actual AT&T ROM (not an Asian or Rogers ROM), you'll be notified of the OTA's. Now, if you're not using the stock Recovery image (that is, if you've installed CWM Recovery), you won't be able to apply the update. OTA updates get applied via the stock Recovery image.
2.
what happens if i do a factory reset on the phone? would i brick the phone? under normal condition that will erase all apps i installed and return it to factory setting, that means all the att bloatware will be back? will i lost root?
If you do a factory reset from CWM or within the phone's UI, you're fine. Root will remain in place, and you won't brick it. It just clears the user data from the phone, and should leave "sdcard" intact. However, I'm not 100% sure what happens if you do a factory reset from the bootloader. So just don't do it that way, unless someone else can confirm that it's okay.
3.
what other things i can do after i root the phone at this point?
You ca use apps like AutoKiller to change your memory management, for one. That's about all I'm doing with root right now. If we ever get custom kernels, you'll be able to overclock your CPU. If you search the Play Store for "root," you'd doubtlessly find some other root apps that you may be interested in.
Hope this helps!
Don't ever ever ever install an OTA on any rooted Android device. At the least, it won't work anyway, or you will lose root. At the worst, you will be stuck in a bootloop. Updated ROMs (based on the OTA's, but rooted, and safe to flash) usually get posted in Development soon after the OTA's go out. That is what you want to install.

I can confirm that it's OK. My phone was rooted and stuck in a boot loop. I did a factory reset. It was reset and still rooted after the fact. So you can do it.
thank you all

Just to clarify, pre-rooted versions of the official ROMs (which often get posted on XDA, as I mentioned) may need unlocked bootloader to install, so this will possibly not be an option for a while. Although there may be alternate safe ways to update (but not OTA). For instance, a leaked 1.83 firmware version is already available as an RUU in the Development subforum. Apparently, its okay to install via RUU, then re-root.
In general, the safe thing to do is to read up on here when updates are released, and see if there is a safe way to update on a rooted phone.

Rooted Tablet went bad...

I rooted my Samsung Galaxy Tab Plus 7.0 tablet with the tutorial from this site:
http://forum.xda-developers.com/showthread.php?p=24736900
It worked just fine for a couple days, then today I powered up the tablet and when I unlock it, it shows a problem loading all widgets, and within a few seconds the screen goes black, then proceeds back to the unlock screen. I unlock it again and this keeps repeating.
I didn't hack anything else, just installed superuser and a couple of other root apps. Really I haven't done anything else to cause this.
I don't even have enough time to go into settings and do a factory reset.
Any ideas? Perhaps in recovery?
EDIT - I did a factory reset in recovery. Is this going to fix it back to normal? I probably won't root ever again.
It probably has no affect, but what root apps did you install?
superuser, busybox, adfree, rom toolbox (which couldnt even detect my root but I never tried anything else)... those I can remember...
Did you install CWM and do a backup?
Im not sure what that acronym is for. I am new to all this. I followed the simple instructions in that tutorial and that was it.
It seems the issue is gone since my factory reset.
I am not sure if the root is still there however.
If there are extra steps to be done after a root it would help to have them with the tutorial....
A factory reset will remove root from your phone. Rooting it in and of itself should cause no issues like you are having it has to be something you installed and I would suspect ROM Toolbox. I'm not sure this app supports teh GTab+ or even has any useful purpose for us as we have no real ROMs to flash. It also contains a ROM Manager and if its the same one by Koush then it will defintely screw up our tablets.

I have done this ROOT like a million times (i'm a flash junkie)... testing the CM9 roms and back to stock again.. never had an issue with ROOTing the stock ROMs..
Suggest you download the latest firmware for your device and flash using ODIN and factory reset. Repeat the flash & factory reset a few times
Maybe you have the wrong clue of what your problem is. To root your tab is just a matter of put a binary called "su" on a directory on your PATH, usually /usr/bin and set it with proper permissions. This binary gives you superuser powers, but there's nothing on it or at least in the process that installs it that makes it interfere in anything without being called.
So accidentally you did anything that went wrong or any of programs that requires root did.

Sorry for taking a bit to reply, havent had the chance to get much PC stuff done lately.
Aaah so you think it was the culprit.... its wierd because when I tried to run the rom toolbox it shown that my tab was not rooted.
Then the problems started... as in my tab was rebooting itself and was stuck in a loop.
I did do the factory reset and then used a root checker and noticed it shown as no root access.
I have read that a factory reset does not remove root... are you sure it does completely?
I'd hate to go through another reset as I have set everything up again.
The only bug I have noticed so far with my tab is that the odd app (so far market and dolphin browser) at times I am unable to go back a page... the page just kind of flashes and stays on that page but does not go back. I end up having to restart the app.
Should I reflash with latest firmware and do a factory reset?
If so... I found this site, shall I use these instructions and firmware?

OPO root dissapearing after cm12 update

im sure this question has been answered for different handsets etc before but i wanted to ask here.
I decided today to root my oneplus one. I had installed the CM12 update before hand and thought that it would not cause any issues. unfortunately after i installed the custom recovery i tried TWRP and clockwork mod and then rooted it. when i booted into the cm12 the root binary was not present and the recovery had reverted to the stock cyanogen recovery.
eventually after many attempts i decided to wipe the phone entirely and install cm11s onto the phone and wouldnt you know, the root and recovery all worked perfectly. i even installed titanium backup just to make sure. everything checked out 100%.
Then I proceeded to install cm12s again, thinking all was good but then it all reverted again. I really do not know what I am doing wrong. I am using the root toolbox that was shown on the root video in the root tab of this forum.
Before you ask, yes i have unlocked the bootloader. i followed the video to the word
I really do appreciate all help and advice given

[Q] "Unfortunately, IMS Service has stopped"

I'm having issues with my Galaxy S6. I used Odin to return to stock, and now I'm getting an "Unfortunately, IMS Service has stopped" error every 2 or 3 seconds. The phone is essentially unusable.
Other Galaxy phones have had similar issues, and I've tried some of their suggestions. I wiped Media Storage and factory reset the phone through the recovery. I tried to find the DRM app to wipe, but it's not there in the app manager. Does anybody have any suggestions? They are greatly appreciated.
Thanks in advance.
Im having that same issue. I bricked my phone for about a week and I had just got the tar files to open and return my device to stock. Is it saying you have service? Ive been looking this up everywhere and have no luck with the s6 problem.

Why did you return to stock? If you are planning to return/exchange the phone, then you may run into trouble if it is unusable.
3 options:
1. Attempt to reflash stock via Odin and hope it fixes the problem.
2. Restore a nandroid.
3. Clean flash a custom rom.

Android lollipop gives you the option to transfer your apps to a new device when you setup the new device. You are also given this option when you flash a custom lollilop rom, because the setup wizard will see this as a new device. However, you should always make a backup of a good working rom setup prior to flashing a new rom or any mods. When I say a "good working rom ", I mean a rom that you might possibly want to go back to, in case your next rom flash doesn't go well or it has major issues that prevent you from using it as a daily driver (which you won't know until you flash it, obviously). The stock rom is definitely a "good working rom", and you should ALWAYS make a backup of stock before flashing anything else.
Since you don't have a backup of stock, then you are stuck with Odin getting you back to bone stock, which apparently isn't quite doing the job. The only other thing I can suggest is flashing a stock rooted rom (eg, no mods other than root). But make sure you clean flash, which also means mounting & wiping /system in recovery. I forgot how to do it in CWM/Phil's recovery, but in TWRP go to Mount, tap /system then go back to the main menu, go to Wipe > Advanced and select cache, dalvik cache, data and system, then swipe to erase. Now you have a totally clean slate.

Ive tried looking online for software thats compatible with my carrier (cricket) but I couldnt find it. The way that I bricked my phone was trying to flash TWRP recovery on my phone. Cricket is through at&t and has the locked bootloader. I used pingpong root to root it but apparently it wasnt compatible with my phone. I'm kinda stuck.

I have never messed with Cricket phones. I know they piggyback on the AT&T network, but I don't know if the firmwares are different. You could go to a Cricket store and look at the display S6 to find out the exact firmware version, and try to find that on the web (posting in the AT&T forum might yield a faster response). But trying to flash TWRP was not a good idea. Good luck!
I was attempting to return the phone to stock so I could sell it. I flashed the Cricket firmware, and ever since then I get the IMS service error. I can't flash a new ROM because I unrooted through Pingpong Root. When I flash through Odin, I only flash the AP .tar. Would it make a difference if I flashed all 4 (BL, AP, CP, CSC)?

Yes it does make a difference to flash it into 4 different parts in case you have the entire firmware
Just wanted to throw my 2 cents in here, i woke to this lovely issue, which was rendering my phone unusable. I use a program call YouMail for voicemail, creeps my friends out when they get to my voice mail. Uninstall this program after wiping every cache imaginable, voila, no more issue. I haven't tried to reinstall it yet since i need to get some work done. Hope it helps in some way.
I have the same problem after flashing the stock firmware thru Odin on my S6 from Cricket. I also tried Factory Resert and Wiping the Cache, nothing seems to help at all. I get the annoying message about the IMS service. I've tried clearing the cache from contacts, ims service but no luck at at. Is there any other ROMs out there for the S6 from Cricket. Right now my phone is completely stock and has no service. Any word of advice would help, Thanks !
Edit: I flashed the CSC file thru odin and it got rid of the IMS error but now I have no service.

Not an expert in any sense of the term, so ignore this if it's dumb. When the OP and others having this issue are bringing your phones back up, does the issue start prior to phone setup? Or is your Google account restoring some app that could be causing the issue?
it didnt solve my problem
I have the s6 edge though ..do i have to wipe and install the rom again??
Unfortunately ims has stopped working pop up
I noticed the spinning sync icon at the top my s7 phone. It was constantly trying to sync my messengers app to the cloud. (I tuned the sync function off an it seems to have stopped the annoying message from popping up. :good::fingers-crossed:
eeee
