Completely Wipe Out S7 and Reinstall? - Samsung Galaxy S7 Questions and Answers

Hi,
I don't know that much about phones. I have a Galaxy S7 from Verizon (SM-G930V) with the software "G930VVRS8CRK2." The phone has been unbearably slow since around November or so. The battery also drains incredibly fast.
Questions:
1. If I reset my phone to factory settings, would it theoretically go back to the speed it was when I bought it? As in -- how much of the slowing down is caused by software updates and system bloat?
2. Is there a way to wipe out my phone and install whatever version was on the S7 back in October/November? I remember there was an upgrade that changed all the icons, and the speed of the phone went up -- it was great. After that, some other update came out that turned it sluggish. Did other people experience this? Am I talking nonsense?
3. Would it be better to install some kind of custom rom? If so, is there one most people use?
4. Is there a way to block future system updates? Is that wise to do?
Thank you for your help, I would appreciate any guidance!

[Q] force new T-Mobile update?

Hello all,
I have another one of these phones on a different line that is not rooted and the user don't want to either.
For the past 4 updates the phone never got ota updates.
I usually was able to get a ruu and update the phone.
I was wondering if anyone knew if a way to force install the new update for this phone?
Mainly important because having so much problems with battery life on that one.
Thank you in advance and for your time.
Anyone?
The battery drain is really being a killer on that one.
Ahh Come on. lol
I have searched for the last few days and can't find anything.
It won't allow me to push it to cache partition either.
Is there anyone that figured out how to do this?

Disable Samsung KNOX For possible Downgrade to 4.3?

As I'm sure tons of you guys know, 4.4.2 is absolute crap. Battery life, lag, GPS issues. There is barely anything good about the update. I am sick and tired of having to charge my phone almost three times a day just because the update (that Samsung claimed in my tech support chat, is "well up to date".) that isn't going to get fixed ever again.
One of these horrible features is Samsung KNOX. Just to get more customers from businesses, Samsung KNOX is ultra secure, down to the very bootloader. Basically turning into Motorola with the no-downgrade thing. Basically making it so not even older custom ROMs will flash. (I haven't flashed a ROM yet. And I'll get to why.)
Now, on HTC devices I have used, If I hated the new update, all I needed to do was Flash an older stock rom, even use an RUU if I needed to. But this update is just plain awful. And thanks to KNOX, there is no way back.
So, I have a few questions to ask.
4.3 DID come with Samsung Knox, along with the Bootloader I believe, which in my eyes, is a very narrow tunnel, but it's there.
You can uninstall Samsung KNOX through the app (If you don't have the app in the drawer, there is a way to set it up anyways. Which I did. and I pressed uninstall KNOX, but the apps are still present on the phone.)
Does this mean the security is off? Or that the 0x0/0x1 flag is off?
Is there a way to root, flash a custom 4.3 ROM, and ODIN back to Stock 4.3?
Is there even a way to do anything development-like on the device without flipping that trigger?
Or can all of this be solved by fixing settings on 4.4.2, not needing to do this anyways?
(if anyone just wants to see how bad the battery is, I can upload Battery Manager screenshots and Gsam Shots as well.)
Thanks to anyone who can provide me with some tips and maybe solutions.

Once your on 4.4.2 you cannot downgrade. It's not even an option
Sent from my Nexus 5
I heard it was strictly because of the KNOX bootloader. Which led me to believe that if I somehow rooted without tripping the 0x1 trigger, removed knox, and then flashed 4.3 through odin, that I'd be able to get back to a system version that doesn't suck.

Alright. But is there any way I can root without tripping the 0x1? Or a way to just save battery on 4.4.2? I barely get 7 hours anymore when I got at least 18 on 4.3.

This probably won't work either, but rooting, flashing a 4.3 CUSTOM ROM w/ touchwiz? Is that possible at all?

Apps are always the biggest culprit of battery issues. If you don't already have it installed I high recommend GSAM battery monitor. That will give you an idea of what is killing the battery the quickest

If you have the app and the root companion for it then it should be pretty clear about which apps are in question
I also highly recommend an app called Wakelock detector (root)

I can't root unless I wanna tip the trigger. Which I don't wanna do. And I only have 2 apps, even tried safe mode, so its definitely the update itself.

If your on NE1 you can root but as far as I've read towelroot is the only option for rooting. As long as the kernel is before a certain date. I can't remember off hand what the date is however. It's hard remembering a log of this as I'm not locked down like most are

Okay. I really like this phone, I just can't handle the terrible battery life this update has given me. It's almost as bad as what I got on my HTC One M7 when I ran sense 7.. And that had BAD battery life. Wish I could flash and root without having to deal with the trigger.
I just tried safe mode and my battery drained the same amount.

I still use my S3 so I understand. I only use it for games and on wifi but it's still a champ
Sent from my Nexus 5
I use mine as a phone since I had a droid ultra that broke, one problem could be the battery is brand new, and I heard new batteries need to be cycled 4 times at least. Or the update is just crap. And Samsung and Verizon doesn't care, so I'm as stuck as I can be as of now, I'm guessing.

Oh i agree. Samsung and VZW came together and truly ruined the S3. Then again they ruined more than a few phones

Yeah. Definitely. Would switch to T-Mobile but their coverage here is absolute crap. Do you know of any good extended batteries or long lasting ones between 2200 and 3000 miliamp hours?
I've never used one with this one so unfortunately I wouldn't be of much help with that. And yea TMobile coverage here is horrible as well.
I know a lot if people used the zero lemon battery which is a lot bigger

Root or Update? Both or Neither?

I have a Galaxy S7 that was originally bought on the Cricket network (SM-G930AZ), but is now on the MetroPCS network. I was wondering if it was worth it to update my phone to Nougat? Also, is it possible yet to root this version? Which should I do first? Can someone give me links to tutorials if this is possible. I do know that I don't want to lose the fingerprint capability or the ability to use Samsung Pay, which I saw on a few forums was a downside to rooting. Has a workaround been found for this yet? I mostly want to root in order to delete bloatware and install Xposed to customize my phone. Also, being able to use Titanium Backup again would be amazing. Any help would be greatly appreciated.
I was asking myself this exact same question.. so I tried both to see what each had to offer. Originally I rooted my phone running on Marshmallow and although it was really cool being able to run Xposed modules, change emjojis to iPhone style, and get rid of ads, the overall conclusion I came to was to not root and here's why:
- Phone was overheating while charging my phone and even running the simplest apps. Tried downloading some cooling apps to help and none were able to truly fix the problem.
- Battery was draining extremely fast. Tried downloading the top battery saving apps with root access, Greenify specifically, and none were able to really fix the issue completely.
- Major lag issues. Scrolling through the phone, opening apps, and specifically running snapchat, everything was pretty much in slow motion. Once again tried downloading apps to help with RAM management and other lag issues. None helped.
I finally came to the conclusion to just update to Nougat, which in itself was a pain since I had to manually update due to losing my OTA access. Overall I like stock Nougat more than Marshmallow but am still in the process of potentially finding a root that will run better on Nougat than it did on MM.
Best of luck mate!
I have the same problem with my S6. A cricket phone on metroPBS. With a base and number that I've never seen anywhere else in the internet unless I read my own threads.

Back To Stock On VS995 After A Couple Of Years Post-Dirty Santa - Couldn't Be Happier

I originally used the Dirty Santa routine on my Verizon VS995, so it remained on VS99513A for a couple of years. Had all manner of issues over time - apps "failing to respond", YouTube not displaying video but rather black screens, green-screen crashes, etc. Finally had enough and used the LGUP process to return to stock and unroot, of course. I probably (assuming, anyway) could have gone right to the latest Oreo firmware with LGUP, but decided to go to the stock version of VS99513A and then just do the many system updates to get current.
It's now happily sitting on Oreo, and knock on wood it's like having a new phone! It's so much smoother, YouTube is working, lol, battery life is an order of magnitude better and it's working like a phone should work. No one knows the future, of course, but today, I'm happy.
Just passing this along, but I've gone from being ready to trash this thing to being able to enjoy it again without worrying about having to dump some $$$ into something else.
I had originally rooted to get around the Verizon mobile-hotspot check, but I have an unlimited plan that includes it anyway, now, so that's no longer an issue.
Possible placebo effect...
A clean stock unrooted firmware may run smoother than a few custom roms, but not smoother than a rooted version of the exact same rom.
I wouldn't give up on root, even if the best ever unrootable phone was given to me for free (Ad-blocking being the primary reason)

Blokada DNS changer. Also working without root. All problems gone. :good: for me the main reason for root is to prevent screen retention. The sucked soooo hart. If there would be an option without root I would also go with an unrooted stock fw.

It's not even a close comparison in my case. Admittedly I'm on Oreo now and not the original Nougat the phone came with (and was rooted with), but it's literally a night and day difference. It wasn't just performance - it was extreme instability, apps that wouldn't work or would constantly go into "not responding" mode, green screens, battery life that was awful to the point where it nearly always needed to be connected to a charger, etc. I'd tap on an app or a function in an app before, and I'd literally have to wait and wait for something to happen at times.
Now? Lightning fast and smooth operation, stability where there was none before, etc. And, as stated, for what I really needed root before (bypassing vendor check for mobile hotspot), it's no longer an issue due to the phone plan I'm on.
I'm not knocking rooting, so don't misunderstand. But for my experience with this phone, going back to stock where I could actually update the version of the OS, as well, has made all the difference in the world for my user experience. YMMV.
Interesting... I haven't tried stock Oreo yet but in every time I flash a new stock rom the phone runs great for 6 months then starts lagging.
oooh meee TOOO! me! meeeee!

Between the GIGANTIC pain in the ass that it was to root this phone (I have a VS995 rooted and on 13a ever since) and all the problems that rooting has caused I'd be ready to undo it all anyway. But due to some problem with internal storage* that started a couple weeks ago, I was fed-up and factory reset the phone. When it boots normally, a check in "about" shows the software status as "modified" but root checker says its not rooted, superSU can't find root (I installed it from play store).. Tried to update via the "system updates" in settings (could not get it to show developer options either).
* The storage issue: I have 50 gigs internal (or something similar) and I get a message that the storage is full and some apps may not work. Not possible, but I humored it and uninstalled everything, cleared cache, downloads cleared, etc ... still showing +/-1 gb free space avail. Factory reset, appears stock, but free space STILL less than 1 GB.
Regretted rooting this phone almost immediately since I still couldn't get rid of certain apps, I had to deal with the camera issues, etc... The only thing positive about it was that my work was unable to install their MDM crap (Mobile Iron shielding Gsuite etc). But anyway, it doesn't look like I'll be able to update the system - I tried it and now it boots to twrp, or boots regularly and then loops around to twrp again. I'm looking for the easiest way to get the phone working (with the persistent problem of internalstorage being full for no reason fixed) and at least reasonably updated. Don't care if it's rooted or not really.
Do you or does anyone have a link to a "play by play" for whatever might work? Its been too long since I rooted it for me to remember the nuances of the procedure so its safe to say that I don't really understand how Android works all that well, so instructions like, "flash xxx 3.2 then flash back to 2 then fastboot and load yer ROM but don't forget the dalvik blah blah" won't work... I'm looking for the idiot's version with hand-holding and everything.
Interesting analysis................ I mainly rooted my older phones due to the need for the mobile hotspot without paying VZ extra charges. However, now that I have the VS995, I was able to download and use the Foxfi app (I paid for the Pro upgrade license) so this left me thinking, do I really need to root my V20 at all? In the past, you couldn't run apps that ran many WIFI tools and other tech'y things, but it seems much of that has changed. I don't run custom ROMs so maybe I don't need to root. Would be glad to hear rebuttals on the subject
I received a new VS995 last week and I flash h910 to get FM radio. I could not be happier as I'm on OREO and the device is working perfectly without any issue whatsoever and with latest mk2000 kernel (2.2 beta) general interface performance is working very well - as it should. Hotspot needed a little workaround bit it wasn't too difficult. I wouldn't dream of going back to stock!

I know it's not straight to bootloader unlock and root this phone but it's worth the trouble. I hope my new fone will last and last untill manufactures change mind about removable batter and horrible new aspect ratio! No thanks V30 !
You're right.
There's no good reason to root the v20. Even rooted you can't do things that other phones can do, like enabling monitor mode on the Wi-Fi. Nor have I been able to get an external Wi-Fi adapter to work on it.

AD BLOCK Yeah they have rootless ad block but they work like ****
screen burn fixes. hows the ghosting?
titanium backup still best option for absolutely all apps getting backed up.
Sorry i have run root too long i cant live without it anymore.
is this happening to just verizon version of LG V20? anyone?

Apps crashing especially in split screen

Is anyone else having problems with apps crashing especially in split screen after OneUI 3 update?
Try clearing the system cache.
Will do. Thank you. I actually reset the whole phone today hoping it would reset to the originally OS, but it didn't work

Whatever the most recent firmware update was is what it will revert to.
It's safer to wait a couple months before installing firmware updates; let others be the Guinea pigs
After a major firmware update a factory reset is a good idea anyway.
Hopefully that got it
So far the new update has ruined/broken the best features of having a fold. Very disappointed. Basically, went backwards and all the features that GoodLock fixed/ enhanced aren't available any longer.

Samsung will update them. Check the Galaxy Store for updates. They're pretty good at that but not always ahead of the curve.
You could take it to a Samsung Experience Center and have it flashed back. Yeah another factory reset
You see now why my 10+ is still running happily on Pie... and probably will it's whole life.
If the firmware is stable, fast and does what I need it to do, I leave it alone.
Without the Good Lock apps I be hating it bad...
