Thank you for this U ROM! But I have 1 question: When making the recommended changes with Kernel Adiutor, Where can I find the I/O field?

If it's the 'I/O Scheduler' field, I can't edit anything there. Can someone please send me a screenshot of what it supposed to look like.

Thank you in advance
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] :
If your rooted you should be able to tap Scheduler and edit the fields. It should look like this when your done.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] DJGhost:
I'm only able to change the 'Read-ahead' field. But when I tap on 'Scheduler', nothing happens.

I checked with 'Root Checker' & tells me I'm rooted. I also went on SuperSU & see Kernel Auditor on the list.

I'm having a couple of issues, one of which I think I've found a solution to.

First, it doesnt seem like I can log into Snapchat with xposed installed. Looking for the Uninstaller at the moment. Apparently if you log in and then install xposed you're good.

Second, I can't use any sort of root hiding application. No idea what's causing that issue or how to solve it. Any advice would be appreciated.

EDIT: Confirmed that uninstalling Xposed will allow Snapchat login. Still can't hide SuperSU with it uninstalled so I'm going to put it back on.

OP HAS BEEN UPDATED!!!

Two major changes:

A respected user has recommended taking the xtouchwiz section out, due to issues with dvfs disabling and other conflicts. It has been removed.

I have included a link to a thread over on the regular Verizon s7 side, in which contains a zip that cures a ton of issues which I have been battling, including no doze and whatnot. I have included that zip as step 3, because it will fix all Verizon issues, no matter if you are on U firmware or on PE1 firmware. I highly recommend flashing that zip.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] mainomain2:
Hey guys....I have a quick question.

I'm on the U firmware rooted but I really want the Verizon firmware back because my signal and downloads speeds have taken a dive.

Is there anyway I can flash the Verizon firmware even though I went ahead and installed the U?
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] psouza4:
Thanks, dajmanjt -- I'm not going to (persistently) hijack the thread here, but I do want to help out a few confused people I see so here's a big ol' reply post with answers, links, and fixes...

No, no, no! Don't use Kernel Adiutor to make any changes, for several reasons. First, it falsely believes that our first physical CPU core controls the settings for all our cores so you are setting max CPU speed for the big 2.15 GHz cores at the 1 .6 GHz speed. This will throttle your performance. Secondly, and more importantly, it's not able to change many other CPU settings that need to be fixed like enabling CPU idling sleep settings, changing the governor for the big cores, adjusting scaling load targets, etc. Uninstall Kernel Adiutor and use my flashable update instead and save yourself the grief.

My flashable update includes the patched imsservice.apk and framework-res.apk as well as verbose instructions for Xposed, so you can cut down the number of steps required by following my guide

That's the SecurityLogAgent app and it's removed in my fix+debloat flashable update.

I have an unroot guide in the S7 forum that includes stock images for the Verizon S7 Edge, too. However, I recommend you try again with my guide and see if perhaps there was a mis-step somewhere that's leading to your poor experience -- you shouldn't be seeing diminished performance at all.

I really feel like I'm probably hijacking this thread a little, but if it helps out anyone who's getting stuck or confused about performance, etc., then it's a win for everyone. Thanks to dajmanjt for his work getting people rolling and enjoy!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
I never had those issues using kernel adiutor on other devices.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] psouza4:
Your other devices probably weren't running cores that have separate settings for each core. We have two clusters of two cores (internally called "little" and "big"). Kernel Adiutor is adjusting /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq, but that only adjusts settings for cpu0 and cpu1 (the first cluster, the "little" cores). Cores cpu2 and cpu3 have their own settings (governor, scaling, frequency, etc.) that don't follow the cluster managed by cpu0. Additionally, the developer's engboot image changes other device settings like setting /sys/module/lpm_levels/parameters/sleep_disabled to 'Y', which causes unnecessary battery drain. Kernel Adiutor doesn't have a way to configure that or the IPv4 settings or various other device settings that got changed with engboot. That's why I developed the fix package. ;D
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
That is correct: but I do have separate settings for those cores on other devices.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] dajmanjt:
I also did not realize that kernel auditor was incompetent in changing the settings that needed to be changed. I will remove that part of my guide and clarify the better way of flashing your mod, including letting it handle the cpu.

Thanks for the info.

Quick question: what would I use to change some other settings besides cpu, if kernel auditor is no good?

Hey bro hijack my thread anytime. I'm just trying to help with the experience I've had collecting the pieces I have put together. Thanks for all that you do for the community!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] dajmanjt:
Yep same here mark. I'm assuming this phone specifically is a no go. I used kernel auditor exclusively BECAUSE it handled multiple clusters on my moto x pure. Developers recommended it. Not so on the s7

Ok...so how do I remove the Volte icon within the status bar? I've done everything as specified and it's still present and very unsightly.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Outbreak444:
Are you running windows? If so, I can help you to an extent.

You will want to open up command prompt from your PC

-Hold down the Windows Key + R

-Type in "cmd" without the quotes and hit enter

Now you will want to navigate to the directory of where your .bat file is located

-For example, if your command prompt directory is located in C:\Users\whateveryourusernameis and you need to navigate to C:\adb then you will have to type in "cd C:\adb" without the quotes.

From there you will want to check that you are in the right directory and that the file is there

-Type in "dir" without the quotes and hit enter. It should give you a list of file names in the folder you are located in, verify that the .bat file you are looking for is there, if not then you're not in the right directory and will need to make sure to go to where it is located.

If you were in the correct directory then all you have to do now is run the batch file from the command prompt window

-Type in "root.bat" without the quotes and hit enter. If there is a problem, the error message will stay up and not close itself out like it probably has been doing.

Now you should be able to tell us what problem you are having so that we may be of better assistance to you.

Hopefully this either solves your problem or allows others to be able to solve the problem you are having, and good luck!

I will say that after flashing the fix and debloat zip, I am getting some weird behavior with the fingerprint scanner. It's very slow and there is a huge delay between read attempts.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] dajmanjt:
I for one do NOT feel comfortable flashing the debloat zip. I debloat myself and only remove what I am comfortable with. The only zip I recommend is the fix zip WITHOUT the debloat script, which is the one I linked in the op. I see too many people having issues with the debloat script and I feel more comfortable doing that part myself with titanium.

I totally agree (and it's my script): I don't like randomly flashing other people's debloat scripts because you never know what people consider 'bloat'.

By my count, it is (a) apps that can be re-downloaded from the Play Store like a few of the Samsung apps, Google apps, etc. that just doesn't need to live in /system, (b) Knox (since Knox doesn't work on a our rooted boot image), and (c) purely junk bloat that is just preloaded garbage. I do have a deeper debloat script in an entirely different forum thread that freezes quite a few other packages, but this is all that I recommend people delete from /system.

Hope that helps!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Alucardis666:
Thanks for updating the op. I will try deleting that folder tonight and see if it fixes it. I wanna love my S7E again. I switched to the HTC 10 as my DD as the S7E got laggy and suffered poor battery life after 6 weeks of me having it. I'm sure root should remedy that with the right tweaks in place.

Thanks again for the quick replies!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
Likewise and getting lots of lag. I only used the fix zip. Not as smooth as before the fix and removal of kernel adiutor. ;(
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] JAYNO20:
I am seeing the exact opposite. Much smoother and faster since I flashed this and removed kernel auditor. Did you turn off dvfs?
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
I thought dvfs was not activated in the zip.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] JAYNO20:
You can turn it off via xtouchwiz. I saw much better performance by leaving it ON. Just wondering if you had turned it off.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
I never installed exposed.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] JAYNO20:
Then I don't know. The performance is way up using the flash file.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] markwebb:
So I guess there isn't a zip file to undo the changes. Looks like I have to reflash everything back to stock. In fact while I was composing this reply the phone froze and rebooted twice.

EDIT: I reinstalled kernel adiutor and changed the CPU and I/0 values back to the originally suggested values so let's see how that goes. So far lag is gone and feels better but let's give our a few days.

You can flash it on the U or the PE1 firmware. I found confirmation in the original thread. However if you are NOT on Verizon then I recommend using the other script, the one for non Verizon phones.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] W00fah:
Just thought I'd report back with how the stock 935U software is.

So far battery life is freakin amazing. The first full day after flashing it and having a fresh start, I got over 4 hours of SOT. When I'd be on a fresh reset on the VZW firmware, id only be able to get about 1.5 hours SOT. It amazing not to have the phone clogged with VZW crapware. Ive only turned off a few things. Two of those things being from when setting up the phone, the google reporting/diagnostic stuff. Other than that, I have everything turned on.

The patch for imsservice.apk seems to do best on PE1 or later. As PE1 is available to flash for Verizon, I'd upgrade, but you probably don't have to. Your mileage may vary.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] drmatthews1:
I have successfully completed parts 1 & 2. After running the batch file my phone restarts and SuperSU is installed, but root was not successfully achieved. Has this happened to anyone else? Any suggestions to achieve root? Thanks!

Edit: I achieved root using this method and everything is working as I'd like. To fix my previous post I used the "PrinceComsy" version of Odin to flash the "Samsung_G935x_QC_Rooted_BOOT.TAR" file. Also, if anyone else is having trouble with the root.bat, I had to put all root files in the directory adb was installed to. Lastly, the xposed framework in the original post is what is needed to flash via FlashFire. In the original post it says to extract this file to find the file needed to flash and an apk. The apk instead needs to be downloaded from the play store (Xposed Installer), you are only flashing the framework.

Oh and one final thing, after my first attempt, everything was working well until a Service Provider Update saying "your device will restart to configure features supported by new sim card." The only option is to press ok and allow it to reboot. I could use my phone while this notification is active, and I was unable to kill it in any way. When the phone reboots to recovery, the configuration fails with "dm-verity verification failed". I then reboot system or power off and the endless cycle continues. I had to follow this guide again to reflash the unlocked firmware and root it. I then saw once I applied the verizon fixes my phone was again recognized as a model SM-G935V (instead of U) and "download automatic updates" was checked. I unchecked this and am crossing my fingers for everything to continue working as intended. Hope these ramblings are helpful for someone...!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] johnboy693:
Not sure if I missed it somewhere in this post, but I tried to flash xposed via FlashFire and when the phone restarted it I couldn't find the app. I also tried to flash other apps this way and nothing is showing up. I do have root access and everything seems to be working fine. Any advice?

Thanks!

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] psouza4:
You'll lose just about everything because they packaged /data and /system in the update and signed it. Depending on your device, when you flash you may have a HOME_ version of the CSC file to flash which does NOT overwrite data. You might try that. You're kind of on your own on that one though -- mixing images isn't a great idea.

Your phone is one of a very small minority, then -- I want to say there's something you're likely not doing exactly right by my guide.

Probably not -- kind of off-topic though. I'd start a new thread asking about what you can and can't do with Flashify with our root and/or a different firmware.

thanks for your detailed step by step guide. I bought Verizon s7 edge unlocked frm USA and am using in India. I just want to debrand / means remove the bloatware and have all the features as supplied by Samsung. So is only flashing 935U thru odin enough. I dont want to root my phone

If you bought the new US unlocked S7 model there is no carrier bloat or Samsung bloat. You can install the Samsung apps by installing the Samsung apk:

So here is something strange going on, and I'm hoping someone can either confirm this as a widespread problem or confirm this is just my issue. I am on U firmware running the two fix zips for Verizon.

Volte works for a bit then quits working randomly. The only way to get it back is to remove HD calling from my account and add it back. Then I power off my phone, power it back on, and it works for a short time. Within an hour it will stop functioning again.

Is this just me or is this something others are experiencing on the U firmware?
