935U FIRMWARE​

Those of you on Sprint that have been locked into the Sprint only firmware now can go back to the beloved U firmware...or flash a carrier firmware of your choice. If you are still on b4, I would stay, but if not, now is the chance to install the U firmware.

Check your bootloader before installing, you may not be able to install carrier firmware afterwards.

Old Stuff

The "U" Firmware will work on any G930 Galaxy S7 (basically, USA variants) and is the Samsung Galaxy Touchwiz OS without carrier bloat. There is Samsung Bloat, but some can be uninstalled or disabled with a program like Package Disabler Pro or just disable it under application manager.

This should not trip Knox and will allow you to flash back to your original stock firmware. Warranty should not void, but I'm not responsible for bricked devices, exploding batteries, crying babies, Earth crushing meteors. If you have a question, best to ask it first!

There is an OTA to PG9 after you install this firmware. Feel free to upgrade after you flash this!

Installation:

1. Download

Updato Firmware Website ​

or​

Sammobile Firmware Website ​

or​

PL2 Firmware Google Drive (post 365 for MD5)​

2. Extract files. May be best to download files over a wired connection!

3. Open ODIN and place the BL; AP; CP; CSC from the rar in the corresponding slots.

4. Place phone in download mode. Power + Vol Down + Home

5. Connect Phone to computer

6. Odin should recognize your phone. If not, you need to download and install the Samsung Driver Files

7. Press Start

8. It should flash the "U" Firmware.

Pit Mapping Error Fix

1. Download the Pit File Here

1a. You will have to down the Sprint PE1 firmware from Pit File Here or Pit File Here

The bootloader changed from v3 to v4 after the PGx update. If you are going to odin the latest firmware, you shouldn't have any issue. Going back to PGx to PCx/PEH will require this.

2. In Odin click the tab that says "Pit"

3. Odin will pull up a Warning dialogue. Click ok.

4. Click the long rectangular "Pit" button to select the pit file

5. Select the file that says "HEROQLTE_USA_SPR.pit" from the files you downloaded from my link.

6. With the pit file nw included, Add the AP, CP, and CSC files again and flash. (may need to reboot and go back into download mode)

7. Now odin the older 'U' firmware

____________________________________________

You cannot root this firmware with the Sprint model. Here are some apps that will give you some root/xposed features without them.

HotSpot

1. Download Shortcut Master Lite

2. Search for LTEfunctionality

3. Click on com.test.LTEfunctionality

4. Launch

5. Scroll down to LTE APN Setting

6. Add " ,dun " to APN2 LTE and EHRPD internet under APN type. That line should read default, mms, dun when you finish.

7. Native Hotspot should work. You may have to do this hack again if you update Profile.

Ad Blockers

None of these block ads on Youtube completely. Some will let you route through their servers to filter ads on Youtube via a VPN.

1. Adhell Uses Samsung Knox to block ads and trackers. Blocks most things on webpages and apps (no youtube), but saves a ton a battery since it doesn't require VPN. Also, it is FREE and well supported!

2. Disconnect Pro Similar to Adhell, but a paid app. Search the Galaxy App Store to buy it. Uses Samsung Knox too.

3. Ad Guard. Best I've used, but is a paid app for the good features.

4. AdClear. Some have had success with this, I've had mixed results.

5. BlockThis! Works well, but caused issues on some webpages.

Youtube Ads

This doesn't block ads, but it does silent and auto skip them. Cygery

Skip Tracks With Volume Keys

1. Frinky Music Controller Allows you to skip tracks with screen off.

2. Noyze Not sure if still being developed, but works. Let's you skip tracks by long pressing with screen off.

Voicemail Issue

I use Google Voice, so this worked for me. It is/was free to integrate your number with Google Voice...highly recommend if they still do it.

Install this apk for Sprint Visual Voicemail apk It will give you an error, but will take away the annoying voicemail notification. Then you can just hide the notification in the android settings and your problem will be solved. May work if you have regular voicemail, but probably not since it needs to write to system.

Doze Related

Remember to whitelist apps you want running in the background...like Pandora, Google Music, etc. I would leave them off at first and if it cuts off when the screen is off, you need to white list it.

For me, these both work best together and I saw a difference running both as opposed to either solely.

1. ForceDoze puts your phone into doze mode without the motion detectors and 30 minute wait. Great app! Does require you to install adb (adb installer) since you have to run a command to get it to run properly. Check Disable motion sensing and turn off while charging

2. Greenify The auto hibernation works great if we had root, but we don't. It works, but can be extremely annoying at times and can drain battery because it may continuously try to force stop/close an app you greenify. Plus, it will take a few seconds to re-unlock your phone immediately after you turn off the screen. However, I use it with force doze for the aggressive doze. I saw a difference in battery life by using them both.

Other Tips

Besides the obvious of gmail/facebook/whatspp/twitter/snapchat syncing

1. Turn off wi-fi scanning

2. Back up my data for Samsung and Google under back up and reset

3. Turn off some features under advanced features in settings...for example, palm swipe to capture if you never use it

4. Location History under Location

5. Change locating method...I leave mine on GPS, wi-fi, mobile, but some people want more battery life and turn it off.

6. Turn on developer options and change animations to 0.5

7. Turn off Always on Display under settings > display. I like it, so I leave it on...but takes about 2% an hour

Old stuff

Has anyone tried the 930U firmware for our Sprint phones (930P)? They seem to have success with it (935U) over at the Sprint S7 Edge forums.

On the Edge forums, they said you can root, but it messes with LTE/call abilities. However, it removes all Sprint bloatware and apparently allows for hotspot tethering.

According to the Edge forums, it is the universal firmware, so it should work on any qualcomm chipset phone. The firmware is for the Galaxy S7 Special Edition ( Link to Sprint site about it )

Anyway, here is the thread on the AT&T forum about it if you are interested. Didn't see a thread or info about here, so I was just wondering.
