I don't mean to hijack the thread but does hotspot work on U firmware? I was reading somewhere that it does now that it doesn't have all the sprint bloat.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
U firmware has functional hotspot. I pay for hotspot so i cant say if root tweaks to bypass would work, though.

Just noticed that there are two different eng boots in your thread, so to speak.

You are informing people to download Nougat_S7_Edge_EngBoot.tar.md5 but giving the link to:

ENG-Root-USA.zip (S7edge_Qualcomm.tar).

[Two different files.]

Dam, I have tried both ways with the new engineering bootloader. Followed step by step. With the original method, I used ODIN to install the Nouget firmware. Went through step by step for fresh install in post #2. I used BK disabler with the xml posted for BK. Turned off Wi-Fi and checked for service. I had LTE data and service. Flashed nougat eng. Bl and lost data. Same with the second method. Once I flashed nougat eng.bl, and ran the root.bat, the phone rebooted and I had lost data again..i wiped cache and factory reset x2 before both ODIN installs of firmware.

What phone are you on? Have you checked which APNs you are on?
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Euronymous88:
You're not the only one having that problem. Both methods cause data and service loss. And the build props edits don't work on the U firmware to regain service. I've tried since different times...all clean installs. And you're right...after flashing EngBoot...service is lost. It was the exact same problem on MM U firmware.

I did, tried the edit I saw earlier in the thread..no go..i want to say there were two, and the were wholesale
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
I will post the apns-config.xml from my \system\etc for comparison and a screen shot of my APN list. The APN settings posted earlier are not the correct ones to gain LTE on the Sprint network.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Bigmar75:
Cool man, thank you..ill try it out tomorrow. Running stock and like the firmware.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
Don't waste your time. Creating and editing apns doesnt work. Changing MNC, which in our case is 120, hides the apn and doesn't allow to be enabled.

I followed your method and jkruse and SPR_UFirm_Root is the only way i could manage any type of data. My sms/voice always works which is great. But without a router/WiFi this firmware is no good for certain. I am guessing these people, including myself, are ones with older devices. Mine being June 2016. I am guessing since we have same model/company that this is working only because your device is different.

Of course changing in buildprop might help but it doesn't solidify the problem.

I have created all 8 apns from ss' below, deleting both WholeSale apns [eng boot] apns first. Reboot, that left me with 3g and my phone app missing.

I have tried Shorctut Master (Lite) with looking up lte [MENTION=4693652]optimummind[/MENTION] (LTEFunctionalityTest) app being selected and messing with settings.

I have tried ##72786#. ##3282# numerous times messing and editing settings/reboot.

Nothing sticks but 3g and 3/4 of the time its no service if i don't have 3g.

I am working on a new way for the people that can't achieve INTERNET data that I think might work. If it doesn't work im leaving this firmware alone because its unstable. But **** i love the speed of U firmware :(, if there's a will there's a way.

Keep in mind i had added BuildProp Edtior strings ro.cdma.default_alpha "Sprint" and ro.cdma.default_numeric "310120". Also changed ro.build.characteristics from "default" to "Sprint". I never had Samsung displayed on notification bar while holding data service.

BusyBox was installed /xbin /bin. I had also touched a little on other LTE settings for LTE strings in Shorcut Master (Lite).

Follow in chronological order.

[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
I figured it out.

Package Disabler/BK disabler is not needed thanks to [MENTION=1949695]jrkruse[/MENTION] with his Supersu Root Installer.

I was on P rooted, wiped cache 3 times, factory wiped data, reboot to bootloader.

In AP i flashed U firmware [BP, AP, CL, CSC] and let it install and run setup. (If you think you're in a boot loop its probably not true because it takes 5-10 mins to reach any setup screen, so wait it out.)

LTE activated, restarted phone, and then i applied Gmail Account. Skip Samsung Account.

After reaching home screen I went to turn on developer options>OEM unlock>usb debugging. TURN OFF verify apps via usb and auto update system.

Turned off Software updates automatically, then clicked manual updates and registered device. Clicked again and let update search.

Auto-updated Security policy in Lock Screen & security. Make sure automatic isn't enabled.

Turn auto update in Google Play Store off.

Close All Recent Apps.

Power Off.

Power On into Download Mode.

Run ODIN Again and insert:

S7edge_Qualcomm.tar into AP. Start flash.

Once reaching home screen, immediately run Command prompt as administrator and redirect folder to:

Nougat_S7_UFitrm_Root_2_79

Type root.bat and then type enter. [Don't run root_with_tweaks.bat]

Device will reboot and don't press any key like it asks you until you reach home page, and device connects to PC by Auto-Run/Opening folder.

When Drive is listed in PC then press enter and SuperSU+Flashfire will install then do a long reboot. 5 mins.

Once at home screen, you will see it is Samsung as carrier. SMS/VOICE should work. MMS/DATA NO.

But we will fix it by going to:

Settings>Mobile Networks>Access Point Names

Delete Wholsales OTA apn by selecting, clicking top right menu, and delete.

Now the Global Roaming APN... select it.

Change the whole APN to

:

Name:APN2 LTE Internet

APN:n.ispsn

MMSC:http://www.mms.sprintpcs.com

Multimedia message proxy

68.28.31.7

Multimedia message port:

Bearer

LTE,

Top right menu>SAVE! Make sure APN2 LTE Internet is enabled and by the dot being blue. LTE should display icon and reset device to verify it stuck.

Flash LTE Icon FIx with FlashFire which is in App Drawer.

Cheers, ty [MENTION=1949695]jrkruse[/MENTION] and [MENTION=5825961]jtash01[/MENTION] for the initial brains.

Nougat_S7_Edge_EngBoot.tar.md5 works as well.

fingerprint works?

Few hours ago went back to rooted G935P fw w/ the April security patch and the fingerprint sensor was giving me an error.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
Maybe because you need to wipe cache again. And no according to [MENTION=1949695]jrkruse[/MENTION], the eng boot disabled this function rooted.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Lazereth:
Awesome write up and thank you! I know you haven't had much time to let it settle in yet, but how's the overall performance feel so far? The G935P root method is just to laggy and unpredictable for me to use as a daily driver.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] radink:
Just to be clear, no fingerprint reader?
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] TheOddTaco:
Fingerprint doesn't work on the QD2 (Ufirm and P firm) update. Looks like the fingerprint sensor is working fine on G935P QC1. I used Nougat_S7_Edge_EngBoot.tar.md5 and didn't try the other one.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] radink:
Wow, I didn't know the P version was screwed too. Is it only when you root or even stock?
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
Oh its way better and i stopped using Govtuner and just bhb kernel, l speed, and Speed Up Swap. Im not going back to P Firmware anytime soon. Idc about fingerprints really because i don't use lockscreen anyways. Thank you sir.

Not until the eng boot is edited.

This is not true.. i just came from QD2 Rooted and that was not an issue. Try your process again and wipe cache multiple times/factory reset. And if you don't update Security Policies/Turn auto update off, the policy won't be updated at all and after flashing eng boot, you really don't have to worry about that.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] TheOddTaco:
Root only.

I went from QC1 to QD2 via ota on the g395p. I tried to set up the fingerprint after I rooted the device using Nougat_S7_Edge_EngBoot.tar.md5
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
It's interesting that even though Sprint and CREDO mobile use the same network, they need quite different post-root adjustments for the APN. CREDO doesn't need anything done. But, Sprint requires fixes to the APN settings.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
Why didnt you provide that earlier? That would've made things a little easier... but i completely agree. What's really weird is that the MNC doesn't need to be changed; usually it's critical. And one APN is steadily holding mms, hotspot, etc. All i know is I'm stocking with U firmware because it kicks A$$!
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
It's rare, I assume, that someone would have service both on Sprint and CREDO since they are separate contracts. I used to be on Sprint then converted to CREDO for their advocacy. So I only had my CREDO version of the Sprint network to play with. In any case, many of us tried without success to root the marshmallow versions of G935U for the G935P hardware. So, I think it is lucky that I was on CREDO and got the Nougat version of Sprint G935U to work without mods following jrkruse' and your work for the G935P stock firmware, in that it proved the principle that the nougat version of U for the G935P hardware could be rooted. This was a case of requiring everyone's efforts. A good case of everyone trying and coming up with the solution !! Again, thanks to everyone. :laugh::good:
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
I understand. Though with so many SuperSu bat installers, eng boot differentials, and apn chaos...i thought this firmware was doomed. I was on PI3 a while back and that saved me from a soft brick. Though I could never get service on MM but I got to flash to PL6 I believe it was. I'm sure OUR method will work for MM. But who tf wants MM anymore lol. Anywho, I've never heard of CREDO and I didn't even know about the similarities. Despite that, yes, we all contributed heavily. It's truly amazing what people will do to help strangers without requesting any money. I feel as if I'm growing-creating these methods [with help obv] and setting a foundation for the community. I know we all must feel like this in some kind of way and I appreciate everyone's hard work and dedication. :fingers-crossed::o

Jtash01 can you add to the instructions to change all animation factors to .5x OR Off in Developer Options as stated by jrkruse. This eliminates/doubles the app transition speed.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
Done!:good:
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Mast3rZero:
How's the speed and battery on this compared to QD2 rooted? Is it worth the wipe?
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
With all the testing I have done, I haven't had a long enough period to collect reasonable battery life graphs, but I can tell the the slope of the battery life on rooted G935U is MUCH shallower than on rooted G935P stock (greatly improved battery life).

The AnTuTu benchmark tests run between ~125300 and just over 136000. It's best to run the benchmark at least 12 hours after root to let the whole system to settle down and cool off.

I'd like to see what others are getting. (I'll post screen shots of my results later)
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Mast3rZero:
Looking good, I think I'll try this method again after I see how it's working out for others. :good:

[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] TheOddTaco:
Rooted once again. The performance is great! didn't need any optimizing apps like govtuner and speed up swap. did it for viper4android. :good:
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] radink:
Love the speed. Hope we can figure out the finger print sensor. I've gotten so used to it, it's hard to live without.
[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] Mast3rZero:
I don't know what's going on but everytime I try to run the root.bat it restarts and what not but once it tries pushing the files it cannot find them. says invalid apk and unable to find specific file. I tried redownloading the zip and moving it into my root of my C drive but no luck.

Update:Got it to work Please don't be a scrub like me and forget to put " cd " before typing the location of the root folder.

This root method and firmware is much more stable. I do notice a slight lag here and there but it's minimal. I'm currently using Viper, speedswap, greenify, and disabled unused programs like all edge functions. :svetius: I'm currently trying to find a work around to the fingerprint scan since I usually use it often.

No you don't have to but highly recommened. SuperSU is used by tons of apps. BuildProp enhances phone with tweaks. BusyBox pretty much owns the show and is a minimal linux administrator, so to speak. It's in control of a lot of apps as well. I would advise you only to unintall BuildProp or not install. BuildProp with this firmware is useless and if you're not tweaking then you're wasting space. Several Kernel enhancing apps have BP strings/settings attached in modular. This particular SuperSU .bat installer removes packages and eliminating the previous use of Package Disabler Pro, BuildProp Editor[Various strings aren't implimented on U firmware]. Jrkruse also said that you can uninstall SuperSU app, which will 100% eliminate clashing grant difficulties and maintain stability. BusyBox was for BuildProp Editor to hold that value change, which is not needed anymore because this firmware isn't totally dedicated to Sprint if you know what I mean.

On it, very nice find btw. Will let you know if its safe.

If you ever enable Disable bloatware in PDP then a lot of important apps are disabled. For instance, samsung apps + wallpaper cropper, external storage, etc.

Make sure if you enabled that option to go through your list and verify. There's a neat little function in the actual PDP app[selected] pop-up menu called Google it.

I'm sure most of you know this but for those who don't upon clicking it tells you in multiple threads/links if its able to be disabled or important enough not to.
