It's to fix the laggy problem with the root. You do NOT need to get an app to change the governor if you just want to use the governor that's alredy running. You can then just flash the govtuner and then select the profile and see what happens.

Also, If you want to install without a clean stock flash, do the following:

Make sure you are rooted on PE1.

Flash v15 Fix

Install LSPEED and follow OP in this thread for tweak settings & install Universal INIT.D & set toggle to on (ONLY IF you do NOT have INIT.D support - This DOES work with SU.D from my tests. (Reboot phone))

Install Terminal from play store

flash govtuner

Open terminal and type govtuner

select the profile you want (balanced, performance, battery)

then ENJOY!

I did do this on 2 phones without resetting to stock, etc... and they had a CRAP LOAD of stuff on them, almost 1000 apps (S7 verizon variant). They had performance increases but I did not get to test - though the people I did this for have told me they LOVE the phones now! lOl

You can change your governor to whatever you want. The GovTuner program supports a CRAP LOAD of governors - every one that Android has, I believe. They do have a list on the govtuner site of supported governors.

Once you've flashed govtuner, just change the governor to what you want, or leave it as is. Then within terminal select the profile you want. Then, profit! :)

I'm still testing out the governors with the 3 profiles govtuner has. Every time you change you governor, make sure you run the tune command. If you want to change the governor but still use the same profile, then you only need to run the tune command! Whenever you change the profile from within GovTuner, it'll run the TUNE command at the same time...

where should I post it. (Obviously, within the S7 Verizon Forum, but any suggestions?) I'm not trying to ask a stupid question, seriously. I just want to make sure I'm posting to the correct location... Hope you dont mind. lOl

Anyone try this on pf2 Verizon yet? I haven't flashed anything from the op yet as it to only use on pe1 firmware, wondering if this will help w/ eng root lag and battery drain? On jkruse rom for stock debloated verizon

Sent from my SM-G935V using Crapatalk
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
PE1 is NOT required unless that's what u have and if you've flashed v15 fix. I installed govtuner on pf2 & many other android devices & it works fine. I was just suggesting PE1 as I figured most ppl that followed the guide to root were most likely on it. But just don't flash the v15 fix on PF2 cause I had very strange behavior. If you want, follow my guide but disregard the pe1 & v15 fix flash... :)
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Toonlinkmaster25:
So I've been running it for like 10 hrs now on balanced and on demand and my battery life has doubled. Definitely worth using.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
That's great! HOWEVER, I'd SEROIUSLY consider changing your governor to INTERACTIVE (Kernel Auditor, etc.) and then change the profile to whatever you want. I suggest interactive governor because it's far better in almost every way!

Again, glad it worked! :)

[Verizon Samsung Galaxy S7 Guides, News, & Discussi] LeftyGR:
Does kernel aduitor now change big/small core frequency independently, or does it still group the large cores with the small ones?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] undercover nerd:
Would this work with tmobile variant?

And I want performance speeds and battery what would I pick balance?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Toonlinkmaster25:
Thanks! I just changed it. I'll probably post my stats tomorrow around this time.

---------- Post added at 12:36 AM ---------- Previous post was at 12:35 AM ----------

It does it independently but I usually change both.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
You only need to use kernel auditor, rom toolbox, etc. to change the governor. GovTuner will change big/small core frequency's for you automatically - from my understanding. You do NOT need to have or use kernel auditor for that. just to change governor's...

Swick

---------- Post added at 02:14 AM ---------- Previous post was at 02:06 AM ----------

I don't see why not! Gov-Tuner has worked on EVERY rooted device I have!

If you want to install, just make sure youre rooted, download and install a terminal app, universal init.d (if you dont have init.d support), and a governor changing app (kernel auditor, romtoolbox, etc). Run universal init.d and select the toggle to "ON". Flash govtuner in flashfire. Run lspeed and use my settings in OP or the settings linked to in OP. Backup settings within lspeed. Run kernel auditor and set governor to interactive - that seems to give me the best results, so far, but I have a crap load of more testing to do. Launch terminal app, run govtuner and select the profile you want (Balanced, battery, performance). PROFIT! (Cross fingers you get insane performance and battery life, LoL)

I've had great results on both firmware, but PE1 firmware is what I know best cause that's all I've used. heh

I hope this helps you!

Here is a link to the guide I setup, with download links, settings, etc...

Don't forget... whenever you change the governor, you MUST run the TUNE command IF you want to use the same profile you've selected. IF you want to change the profile, then you need to run govtuner and select the profile you want to use! (Just a reminder) as ppl FORGET!

If I understand right, I can use the OP instructions to root and install xposed on pf2 M6.0.1? I just don't need to install the v15 fix?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] kuduku:
Any way possible to root, set it up as per requirements to include debloat, adblock & others & again unroot

The method in OP using Odin again gets you back to factory state with bloat in Back to stock guide
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
Some ppl have reported that installingoes v15 fix on pf2 causes trouble. I know it made things funky for me, sadly! (V15 fix was AMAZING work. He deserves a lot of credit) and some ppl have installed it without trouble on pf2. In any case, I'd suggest holding off with installing v15 if your running pf2 firmware. (But that's just my 2 cents - besides, what do I know, lol)... heh
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] MrWhite0429:
I dont know if anyone has followed up on the XPosed Reboot/Reset issue anymore. However I read in an earlier post that possibly the Security Permissions updating could be causing the reboot/Splash screen issue.

Well as an update of sorts,

I installed xposed, cleared cache.

Froze the Security Policy Update in Titanium Backup

Installed a few Modules in Xposed.

Reboot/Clear Cache again.

So far ive been running great for over a week now. With No force closes and ive rebooted multiple times a day to test and see if it gets hung up anywhere. So freezing the Security policy updater seems to have worked. Im testing further however to be positive. Im just passing some of the info along for those scared to install Xposed again.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] Toonlinkmaster25:
Thanks I was actually just wondering that! I think I'll reflash xposed too then.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] newuzer1:
Thanks for the update, keep 'em coming! I'm sure there's more than a handful of us holding off on xposed till its confirmed it is not causing issues.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
Thanks for the info - very helpful. I actually disabled the security policy update right after I rooted (and installed TiBkup). That might be why I've not had a problem with XPOSED. Guess I'll chalk that up to INSANELY DUMB LUCK. (I guess it's better to be lucky than good at times? - Then again, what the heck do I know?)

Again, thank you - it's VERY appreciated!

The only thing ive noticed is that sometimes the Reboot Process takes a tad longer than normal. The other day I rebooted and the phone sat at the splash for a good 30 to 45 seconds, then it proceeded as normal. Possibly running security verification perhaps?

[Verizon Samsung Galaxy S7 Guides, News, & Discussi] LiquidT:
If I'm on the s7 edge SM-G935V running PF2 Firmware I DO NOT FLASH THE V15 FIX... Right?
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] LeftyGR:
The one for Verizon, no. You can flash the universal.
[Verizon Samsung Galaxy S7 Guides, News, & Discussi] swick1981:
This is extremely interesting - I was rooted, running xposed and installed v15 fix (the generic one) on my G930V running PF2 firmware - I did NOT install the verizon variant v15 fix, instead I just the universal version and boy did that cause a BUNCH of issues and trouble. Don't get me wrong, I LOVE the v15 fix. It fixed a LOT on my PE1 firmware running S7. And I'm VERY grateful to the DEV for this flashable tweak / fix. HOWEVER, the universal v15 fix caused my s7 to behave VERY funk-ily. So I tell people with alternate firmwares to hold off on the v15 fix. Use the individual fixes that the OP lists after the root process, in the "RECOMMENDED TWEAKS" section. Those individual tweaks / fixes should take care of everything, but do not use the LAG FIX. Instead, you can use my guide and that'll do the job fixing your governor's Tunables. I can attest to having insane results (in a good way). Never before have I seen this type of speed in a phone - goes to show you the manufacturers start with a really fast device and slow it WAY down to give longer battery life. *SIGH* - So depressing with what they put us through... UGH!!!

I think I figured out the 2nd and 4th bullet. You have to turn off Fast Cable Charging under Settings > Battery. Pretty annoying if you connect your phone to your PC often.

I'm thinking the 1st and 3rd bullets are operating as the developers intended.

MOST SIGNIFICANTLY, the pink/magenta flashing/overlays on the screen reoccurred after turning off Fast Cable Charging and connecting to PC so that bug/instability remains.

Update on VOLTE Icon - It randomly disappeared and hasn't come back. I've switched Airplane Mode on and off again many times and it hasn't come back. :confused:

not root permission denied

Hi All, Not my first rodeo, but my first Verizon S7 Edge. I have been using the phone for awhile, but this is the second time it went into a boot loop for no apparent reason.

First two times I was able to reinstall the U Rom and re-root. I am trying to root again, but when adb tries to mount at the beginning of the sequence, I get permission denied for the first few entries, and of course the root procedure does not do it's thing and I am left un-rooted. Any ideas?? Constructive criticism welcome,

Thanks in advance

im new to rooting. it is currently showing an android is starting screen.

should i just go into flashfire and wipe the dalvik cache?
