Quick question for someone who may know, or have experienced this while on the U firmware:

Last night around 8 my phone starting to become increasingly laggy, to the point where it wouldn't respond to button presses for minutes at a time. All the while, a message would keep popping up saying "Unfortunately, the process android.process.media has stopped." I went ahead and uninstalled my xposed modules (youtube background play, youtube adaway, swipetoseek, pixel dock, and fingerprint enabler) which didn't seem to do anything. Then out of no where, right as I'm getting ready to put it into download mode, it's fine. I've been running the rooted 935U firmware for about a week, and haven't had a single issue. Does anyone have any theories as to what could have potentially caused this? I am about to sit down and go through the bugreport to see if anything looks out of the ordinary. Thank you!

Failed Root Attempt Help

I've got a few questions about the whole root process. So I had a pretty pathetic attempt at rooting my s7 edge. After I flashed the image I got stuck in a boot loop on the verizon initial startup screen. Thinking this was normal, I went into recovery mode to re-boot the system. When I came back to my now wiped android it was slow and buggish. Certain apps like my vpn crash before I get the chance to really use them. Also there's a notification from the SecurityLogAgent saying 'Unauthorized actions have been detected. Restart your device to undo... blah blah blah'. When I restarted the device it goes back to the big blue screen with the android saying it's installing updates. Then the update installation fails and takes me back to the verizon screen except this time it doesn't get stuck in the loop. I'm a little concerned for the security of my phone as I used to use banking app and Paypal on there (deleted after this happened). Please help me just get back to my normal stock samsung! Thanks in advance

I did several searches and couldn't conclude if flashing the U firmware on the Verizon S7 Edge will give me all the bands needed for T-mobile. I even tried search the tmo thread but couldn't find an answer. Anyone know if the Verizon S7 edge version (once flashed to U) will unlock all the bands?

I would like to know before purchasing the S7 edge verizon version as it's much cheaper.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Justin.ice:
Verizon has the most range in bands, so you should be covered at least that's what I was told by a best buy employee. But this is what i found:Cheat sheet: which 4G LTE bands do AT&T, Verizon, T-Mobile and Sprint use in the USA?

Carrier	4G LTE Bands	Frequencies

Verizon Wireless	2, 4, 13	1900, 1700 f, 700 c

T-Mobile	2, 4, 12	1900, 1700 def, 700 a

Europe	3, 7, 20	1800, 2600, 800

Yes you can but you need to find the U firmware with build number PI3. Also the only problems I encountered where a bit of lag but I fixed that by installing Stang5litre ROM in the ROM section. I can't answer your Nougat question unfortunately

This is just a firmware upgrade. You need an unlocked bootloader for TWRP which currently can't be done.

Does anyone know if flashing carrier modem on the latest 935U is any better? I read someone saying he gained twice the speed or something after flashing tmobile modem. He is on tmobile.

I'm on Tracfone (AT&T) and flashed the tmobile modem just out of curiosity. So now I have a Verizon s7 edge with latest 935U and tmobile modem on it. I didn't notice any real difference. Maybe flashing AT&T modem will make a difference, I don't know.

I'm running a 935A with U firmware and T-Mobile APIA modem, I have noticed better signal throughout the house compared to the U modem, haven't tried AT&T modem yet on the U firmware. Watching signal strength in settings/about device/status/sim card status.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Quickvic30:
I'm actually on ATT, and yes it helps quite a bit, I've noticed better signal just about everywhere with the APIA t-mobile modem vs the U modem. I haven't tried the ATT modem on the U firmware but on ATT firmware and modem my signal was still not as goo as the U firmware with the T-mobile modem.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] bugity:
Hello all,

I have a question, I am having trouble getting the CPU govenor changes to stick on my friends phone. I successfully rooted my AT&T s7 active with no problem but his phone isn't cooperating.

His phone is on PI3 so we flashed all necessary PI3 Odin files followed with the engineering file. After we flashed SU successfully getting root access. Busybox was then installed in the propper location. Govenor was attempted to be changed using Trickster unsuccessfully then attempted with Faux Clock unsuccessfully. (Both of the apps worked on my S7A to make changes stick after reboot).

Any idea what's causing changes to revert after a reboot? Stang Rom was also flashed at one point to see if changes would stick in that rom but we're unsuccessful as well so phone was put back to "stock rooted" PI3.

Thanks in advanced.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] studiorat:
so nobody has an answer on the question? Has, anyone seen the supersu cant install the binaries error upon installing Super Su via adb, and has anyone found a solution?
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] bugity:
Just to double check, you did flash the single ap file after flashing the handful of files in Odin? If so and you still can't get root to show up here are two possible solutions. First and foremost the Super SU file that gets installed will ask you to update binaries but DO NOT it is perfectly fine that it is out of date and it needs to be. It's possible that the Root.bat isn't fully installing root when you run it. Here is what you can try Ctrl+Shift+Right Click in the folder containing the root.bat. then click on "open command window here" . Then type in "root.bat" and hit enter while your phone is connected to the computer with USB Debugging enabled. This will keep the cmd window open and ensure the root process doesn't exit prematurely. Let me know what happens after you do that. Check to see if your phone sees root with root checker app.

I am on the same boat. How can I flash the U firmware and the T-Mobile modem? Could you point me in the right direction.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] studiorat:
I did install supersu via cmd ....and the app installs but says no binaries are installed and yes I flashed the single ap file as.... I posted in my OP this was the 2nd post after 3 days of no response ....I thank you for the suggestions ... Root finally took I had to downgrade to the U firmware ....and an older super su.....but now xposed is wonky I need to get that to function...

Unable to apply root

I followed all the steps and installed the firmware. However I have tried repeatedly to install root by double clicking the root.bat file. Each time CMD screen flashing but nothing happens. I have confirmed that I have ADB installed and that my phone has been recognised when I run adb devices. I have confirmed that USB debugging is enabled and that my USB cable is not loose or defective. I now have an dm-verity verification error when I boot into recovery to do a factory reset. I am also unable to install stock firmware. I have tried multiple times and have used both versions of Odin.

What can I do now to solve my problem. I would rather go back to stock without root than to keep this new firmware without root. Can you show me how can I restore stock firmware on my phone please. I would appreciate it very much.

Did you flash the custom Boot image in Odin? You can't root without doing that step. Also I have gotten Dm verity verification error before but I was still able to flash to stock or do a factory reset. If nothing works I recommend you flash to stock PH1 using Odin and try the steps to flashing U firmware again. You can get the stock files and Odin in the link here:

Yes this works for you. If you are on PH1 or PI3 you need to flash the newer PI3 U firmware you can get from this link bellow. Follow all the same steps but instead of using the file in this thread, download the PI3 U Firmware from the link bellow.

I would suggest using Device Control [Root] from the app store and once you set the governor there is an option on the very top that read Apply on Boot and also an option just below the governor selector that read Lock Governor. Use those options and that might help. That is what I use on my device. Hope it works.

Is it worth it to flash the U firmware if I don't want root? I use Samsung pay a lot. It'd be great to unload all the Verizon garbage (as opposed to just disabling it with package disabler). Do I need it rooted to set up all the VZW fixes and keep them, or can I root, set them up and unroot to keep pay working?

Thanks. I used to flash quite a bit years ago with WinMo and early Android phones, but not at all since. I'm a little behind on this stuff.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Snakehn:
I flashed mine back in November and never looked back, I didn't apply any "fix" as I found nothing to fix, the only thing is missing is verizon's video call, is not broken it just doesn't exist on this rom with I'm fine with that.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] looney2388:
I kind of switch between the two firmware g935u and g935v. G935v has FM enabled and the visual voicemail. G935u is slightly faster,less bloat and has white pages. I would definitely pick g935u over g935v firmware overall. Use Google voice for visual voicemail.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] tedkord:
So the U firmware will lose me the FM radio? I do use that. Oh well...
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] shouthouse:
Hello. I'm sorry for this question but I want to make sure I'm in the know before making a decision.

I'm trying to get a benefits list for why to do this. I currently have the SM-G935V updated fully. I am going to be taking my phone to T-Mobile in the next months and this seems like a good way to get rid of all the Verizon junk.

1. If I'm completely updated will I need to root?

2. If I do, then when I flash the U firmware then can I regain ability to use Samsung Pay?

3. Will I lose any functionality by doing this?

4. Could a quick "Why" section by added to the OP? Just a quick overview of why someone would want to do this just to confirm.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] FoxyDrew:
You will not need to root, and the only functionality you will lose is FM radio, and all the Verizon apps (My Verizon, VVM, etc.), which if your switching to T-Mobile you can't use anyways.

As for "why", this will speed your phone up and remove all the bloat.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] shouthouse:
So I have understood perfectly. It's always nice to have someone ease your mind though. I thank you. Your reply was exactly what I needed.

On another note, if this download is taking a long time for people it may be worth downloading Citrio. Took my speeds from 300KB to 2MB.

EDIT: Well I'm not sure what is going on but I followed the steps exactly. I'm having a similar problem to what some others are having. The first ODIN fails and the second one gets stuck in SetupConnection.

Now my phone won't boot into OS. So this is fun.

EDIT 2: OK got it. Had to use like 5 different cables and a different computer and a different firmware but it works.

Random question for you all....

Should this be just as fast as the factory setup? My father in law has the same phone and running AnTuTu Benchmark, his total numbers show 147,725, while mine only shows 117,646.

I was running Stang5litre, but got sick of the lag, so i flashed this and am happy. Much better! Am just kinda wondering if I should expect faster? I did root and applied the fixes via flash fire.

Thank you!
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] FoxyDrew:
If your rooted your performance and battery life still won't be as good as an unrooted device, fixes or not.

[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] xometer10:
Thanks so much to everyone on this thread! I'm on ATT also and the ATT thread was a bit harder to follow and I kept running into SHA256 problems. I came here thinking I would try whatever version of Odin was linked to, I tried and finally I had success. I have two questions:

1. I used the entire package. The firmware is for the 935U- which is the unlocked mobile US variant that works on all networks, correct? Is there really a difference in the firmware that's carrier dependent? If so, should I re-flash?

2. I also flashed the t-mobile modem as soon as the 935U flash was complete. I had a different 935A on stock ATT and I couldn't stand it. Hardware failed and I got a replacement and Ive been following the steps here.

Thanks again- and any comments on user experience since? No significant issues? Really appreciate everything. The information is invaluable. I was losing my mind with the ATT variant and everything I couldn't disable. But I just want better battery life. If I don't get it- I'm ready to give up on Samsung.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] tedkord:
Ok, I'm thinking about doing this. Haven't installed a rom or kernel since my S3.

Would it be possible to flash the U firmware, root, flash Verizon specific fixes, then unroot and use Samsung Pay?

Also, will the U firmware fix the awful Android System battery drain I get?
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] FoxyDrew:
You cannot unroot once you root, unless you completely flash back to a certain firmware, so no.

The U firmware should help with battery life, unless you root it, then battery life (and performance) is garbage.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Quickvic30:
The U firmware ran great without a hitch on the ATT but the nougat beta came out and I had to try that, VERY impressed with it. The battery life is amazing, its fast and very smooth! I can usually get almost 2 days and 6-7 hrs of SOT out of each battery cycle. The new features are great also, you should check it out, you won't wanna go back to MM after lol.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Ethan9987:
