Thank you OP for putting this all in one thread, and being so helpful. It's been soooooo long since I've had root, I forgot how to use Titanium Backup!
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] morrowa2:
The root process went smoothly for me, but one thing I cannot do since rooting is transfer files from the computer to the phone or vice versa. There used to be an option when you pull down the status bar to use the usb to charge, transfer photos, transfer files etc. I don't see that anymore, and the computer doesn't seem to recognize the phone, even after installing Samsung drivers. Anybody else have this problem, and is there a solution?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Oatswesow:
Go to Developer Options>USB Configuration and select MTP. You need to do this every time, otherwise it defaults back to charging.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] jayfried:
I didn't care if I lost everything for the possibility of root, no backup and all is root (right) with the world, maybe just me.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] BlueLightNight:
FlashFire requires root does it not? Thus not so useful for creating backups before attempting initial root.

As there are a few posts of people needing backups after the fact, I recommend adding steps to the guide covering or at least recommending creating backups. Helium is a good options, as was suggested. Also SmartSwitch, which comes pre-installed on the S7, is capable of backing up to the SD card and is another good option. Go to Settings > Personal > Backup and reset > Open Smart Switch. Tap More > Transfer via external storage > Back up

I am, for sure, not running Greenify or Amplify. The only think I can think of is Gravity Box, but I don't see anything in there that would cause this.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] jmill75:
It did not. Reverted back to stock unrooted image, phone is back to being really fast. cant believe more are not talking about this.

Not complaining as I know there would be drawbacks to an early root workaround. Just think I will hold out for now.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] CVertigo1:
He was talking about backing up prior to editing build.prop, so he would already be rooted at that point.

Everything But The Root

So I've been playing with this since Tuesday night when I heard about it. TLDR no root. I have a VZ S7, running the PE1 firmware. I have no problems going through the entire process; everything completes with no errors. The boot shows the custom and open padlock logos; I have the screwy looking VoLTE icon and the security alert notification and so forth. SuperSU gets pushed and installed.

BUT, Root Check shows I'm not rooted. Trying anything that requires root results in a message "No Root Available" or whatever. When I open SuperSU it immediately says "The SU binary needs to be updated."

Anyone got some ideas why the root isn't working?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] CVertigo1:
Did you update the binary?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] psouza4:
I'd make a backup, wipe clean with my unroot guide to flash a stock PE1 image, and try again (I had an issue while playing with deodexing the ROM and had to start over myself, so I know it's a path that works). It sounds like you did everything right, so that'd be my suggestion.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] TCPDump:
It might be worth explaining to folks *why* they have the issues that they do. Just so everyone realizes what they are working with here, this is an "engineering" boot image. This was designed for Samsung and partner engineers to use to develop the complete versions of the OS that eventually get rolled out to customers in its final form. As such, these kernels typically have a lot of extra logging, have zero concern for CPU utilization and efficiency, and occasionally have bugs that aren't in stable released kernels.

This is also why you're able after flashing to modify your system partition and still successfully boot. This is why after flashing the engineer boot image with Odin you see laggyness, you see weird property settings, etc. I saw a thread where someone had made a flashable .zip file for fixing almost all of the problems at once. I can't seem to find the thread now, but I did backup the file. If anyone needs it let me know.

Plug your phone into a computer with ADB > Type "adb shell" > once in a shell type "su". Let us know if your prompt changes. Also, uninstall and re-install the SuperSU app from the play store. I've seen a few VZW devices around the office here in which we had to do that before it would update and work.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] chadhoard:
This morning, I noticed the icon of VoLTE (with out the tornado) on the status bar. Not sure what I did, but I lost that, and the Unlock image at boot. After uninstalling & re-installing SU, the lock has come back, but not the VoLTE icon.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] CVertigo1:
Go into /system/

Do you see a directory for CSC? I just ran into the roaming issue after re-flashing the system with FlashFire, and found that the CSC directory was missing. I re-flashed the CSC tar in FlashFire and it fixed the problem. This also brought back the APN settings that people were missing. I guess you guys that had issues with roaming and APNs had flashed the system, but not the CSC part, right?

Thanks for being so active and helpful.

Is it a known issue that data isn't functioning while on a call?

Also I still get black VoLTE icon sometimes.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Skizzy034:
I hope he didn't try flashing the engboot. Although it would probably just give him a fail and not flash.

Supposedly, Snapchat won't work if you installed xposed. You need to uninstall it, install and sign into Snapchat, then reinstall xposed.

This black VoLTE keeps showing up still after flashing v15.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] FilthyFord:
Did yall follow the guide in the OP. I know that I'm on AT&T but my steps were, 1 factory rest, 2 boot into download mode, 3 flash eng kernel, 4 boot up and root (no bootloop) 5 run fix and debloat zip fires via flashfire, 6 tweak kernel using the guide in the OP (amplify and greenify) modded my speaker to be louder. Let it settle in for a day or so. It may be still laggy at first but let everything settle down. I don't have any lag. Runs smooth.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] airos4:
So I'm running a Verizon S7, engboot, root, running V15 of the script and having followed the speed guide. Overall I get similar performance to stock after a few seconds go by, but for unlocking the phone and the initial interface it's quite noticeably slow. I don't seem to have data during a voice call. The camera app is extremely laggy regardless of the situation I'm using it in. And most interesting, when I use my Pebble to dictate, if the phone is in Doze from Greenify it will fail and say "No Internet connection available".

Having said all that, my battery life is simply phenomenal now relative to what it was. Anyone know any tweaks that might address the stuff I've seen directly?

---------- Post added at 10:00 PM ---------- Previous post was at 09:55 PM ----------

One last thing - can't get rid of the hurricane icon and VOLTE icons. Every time I flash the scripts it goes away for a while, but it keeps coming back! Installed the other version a couple times too, but temporary only. Weird.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] ickedmel:
Yeah my idle time as improved but my phone dies a lot faster when in use it seems.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] byte9:
It does, as fact it's much worse than stock. It's a freedom trade off. I respect the work done by OP, the best has been made out of a bad performing phone post root. It's 75% if i had to put a number on it. I've done everything, have no out of line wake locks and my phone still gets hot much much hotter than normal and battery drain is not in line with pre-root.

All that out of the way, you have root. How important is it? Some will deal with all of the negs to have the big positive. I've not decided yet where i land.

Created a Fix for the Annoying Loss of MTP on reboot

To the OP and anyone else I created a simple shell script set to run on startup that (at least for me) fixes the fact the usb keeps reverting back to charge only, as stated to the OP in a PM, their is an exposed module for this, however it only saves the setting until you reboot, in which case you have to go back to developer menu and re-enable, its annoying and a waste of my 30 seconds every single time I need it lol so I fixed this with this

In the /data/s7startup folder I added a new file named s7mtppersist.sh

gave it the correct permissions chmod 700 (in this case) and added these lines to the script

once my phone rebooted it indeed held the change WOOOOT!!!!

Just thought Id share

#!/system/bin/sh
su -c setprop persist.sys.usb.config mtp,adb
su -c setprop sys.usb.config mtp,adb
exit 0

also too as a side note anyone on verizon wishing to use dialer codes can change the file

/efs/carrier/HiddenMenu

it only has one word in it "OFF" change that to "ON" no quotations reboot and dialer codes will work Ex *#0*#

gets you into one of the test menus

Silly question... does using Knox increase battery consumption significantly? I ask because I use it for all apps I do not want my kids (3 and 5 y/o) to have access to when they play with my phone. It's proven quite useful. My 3 y/o daughter messaged one of my wife's best friend's husband when playing with my wife's LG G4 and the message had a bunch of emojis that could have easily been interpreted as steamy. My wife didn't notice it for a month and it could have ruined a life long friendship. I don''t want to risk that happening to me! In my case, can one run the script in the OP to debloat but modify it to keep Knox (or add Knox back after running the fix+debloat script)?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] cuezaireekaa:
I don't think anyone in these forums has used knox.. especially for what you're using it for.

there are some better apps in the Play store called app block etc. that you can even use your fingerprint for, and it doesn't allow anybody to get into your apps I would ditch Knox all together

Won't the kernel tweaks part mess with the the tweaks in Psouza4's zip?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] kansaswaldo:
Just out of curiosity, did you do a factory flash prior to root? I did to resolve some odd in-app billing failures. As a result, I'm getting amazing results. Heat is less than stock, battery life is consistently great (7-9 hours SOT and 2+ days without having to charge), and performance is amazing.

My order of operations was as follows:

Flash factory image per unroot section of OP.

Follow instructions for root.

Flash latest fix+debloater (make sure SU enabled at boot is checked).

Follow OP's performance tweaks using Amplify, Greenify, and Leandroid.

It feels like a whole new phone, and I'm confident I couldn't achieve this level of performance and efficiency without root.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] byte9:
I did, fresh empty build to root. Did all the tweaks. Like most others the phone ran poorly after all the tweaks. Poor in scale to stock, that is. I do not believe that you're getting less than stock heat and 7-8hrs sot without a screen shot.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] kansaswaldo:
I figured a lack of screenshot would come up. :) The OP has posted some somewhere in either this thread or his performance one, and my results are very similar. I'd be happy to take a couple as well over the next couple days (I don't use my phone 7+ hours a day, so it'll take 48 hours or so to collect the data).

Before I put my phone on the charger tonight, I was at 42% after about 4.5 hours SOT. I also only burn about 1-2% overnight while it's in sleep if not on the charger. I can neglect to charge it tomorrow night for the battery stats.

Brightness stays at the lowest usable setting whenever in use and not showing off the screen. I also do not use the AOD since I hate it. Only apps actively syncing throughout the day are Gmail, Google stuff, and Weather Underground.

You could say I'm a fairly light user. I don't really do the whole social media thing and maybe check Facebook once or twice a day. It remains hibernated whenever not in use. The bulk of my SOT is browsing the Web mixed with the occasional Pokémon Go.

Results will vary depending on how you use your phone. I have a pretty minimalist approach. Heck, my one widget is the stock clock+weather.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] byte9:
Well, no worry. I'm done with the eng boot root. If a better version comes up i may go back but I do actually use Samsung pay often and long game once N comes out I'm not skipping it to keep this root. I only ended up rooting to correct some xml in csc for volte to get back to stock and decided to give it 48hrs. I did all the steps and gave it a day to settle and it would get hot with mild GPS and under load was definitely warmer. Any who, to answer your original query. I did all the things. I'm a long time multi device root user that dabbled in aosp development who at this point just wants sh÷t to work without 5hrs of maybes.

I just started playing a new game today and when it loads up, a popup appears saying something like "phone is in power saving mode which may effect framerates. Recommended to turn power save off" But I don't have power saving mode enabled.

Could this have something to do with one of the tweaks I did from this guide?

Trying to figure out what's causing it...
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] kansaswaldo:
As a multi device root user as well, I can understand that. I actually wasn't going to root this phone (my daily driver) since my Nexus 6 is my fun device to mess around with aosp development and such. I figured what the heck and was actually pleasantly surprised. I may keep root since I can always go to N on my other devices. We shall see.

---------- Post added at 03:51 AM ---------- Previous post was at 03:42 AM ----------

I could be wrong, but I'm 99% sure nothing in this guide will enable power saving mode. The extent of my gaming is Pokémon Go nowadays, but I haven't seen any pop-ups regarding power saving. I also didn't notice anything in the scripts that would trigger that even while toggled off in the settings.

Hrrm. Alright. I'll keep looking. I haven't done much since root. Just followed this guide. Installed xposed. I did install Lspeed last night. Didnt mess with it much.

I'm having some serious battery drains. Verizon s7e. Everything has gone great so far. Got Xposed going good. Only modules I'm using are amplify and greenify trying to narrow down battery drain. Bought the pro version of amplify and killing wake locks and not sure if I should touch alarms. Need some help. Kernal adiutor is set to ondemand and the phone is running really really fast and snappy just need to iron out this battery drain.

If you are using this guide, I wouldn't recommend using kernel adiutor. The fixes supplied in the op are far superior for things like battery life and heat,and kernel adiutor may override some of the settings.

So for what it's worth here are my settings in Greenify and the things I'm limiting in Amplify. I'm posting these because my doze STILL wasn't working, even with the CPU fixes from this thread. Once I reevaluated the things I was limiting in Amplify and adjusted my settings in Greenify, my doze started working flawlessly. Try these settings out and see if they help. My battery life is now quite good. Of course I'm not going to post a screenshot of all the apps I've greenifyed, that's your call on what apps you want too Greenify. I've greenifyed most of the Samsung apps and most of my user apps. I think the key is NO SHALLOW HIBERNATION and only limiting a few known items in Amplify.

Try flashing an earlier firmware; you're trying to flash F2 on your B5 and I believe F+ has a new bootloader. Other tips I can think of: make sure you're using the Odin from my guide, but if that doesn't work I have heard that other Odin versions work better for other people. I'm just guessing at this point at stuff that can possibly help since it seems like you've checked the obvious things. You may also want to post in the AT&T forum if anyone else with your model of phone is experiencing the same issues flashing stock. Finally, I'm assuming you actually verified the MD5 matches in case you got a bad download.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Exleh:
Well, I am going to try a full restore and start over today. My performance is hit or miss. Some times it's excellent, far better than stock. Other times (like today) it'll take up to 30 seconds to open the dialer. Also battery life is hit or miss. Can't afford pro versions of the apps in your guide but I figured I'd at least get close to stock. Anyways I'm gonna try again on a fresh restore and see how it goes.
