[ROOT] SM-T707A - Lollipop with SuperSu - Xposed & Debloated - Part II

Root SM-T707A on Lollipop with SuperSu - Xposed & Debloated - Part II
Where are we right now?
* Part I: Flash Stock Lollipop 5.0.2.
* Part II: Gain Root access for Lollipop with SuperSU. <---- YOU ARE HERE!
* Part III: Flash Xposed Framework thru Flashfire.
* Part IV: Debloat the tablet from both AT&T and most of Samsung stuff.
* Part V: Improve usability and aspect with Xposed Modules.
Once again, some words of our sponsors: NO, I'm NOT resposible for any consequence originated from the use of this guide, being that the death of your tablet, or your smart tv, the Panama Papers or Luis Suarez just playing rough with Filipe Luiz's foot. Whatever happens to your tablet, it's ON YOU.
Introduction (PLEASE READ!):
This guide works as a continuation of Part I, so we assume you flashed KitKat and applied Lollipop updates as described.
If you are already on Lollipop and have several weeks using it, of course you can try this guide, but I STRONGLY SUGGEST to start from zero, backup your files and use the guidelines on Part I of this guide.
Part II: Gain Root access for Lollipop with SuperSU
IMPORTANT - During the first boot on our brand new lollipop, don't try to connect to your WiFi and remove your SimCard if availble before even selecting any option. We don't want any internet at this time.
Our first move in Lollipop is to Reject all the AT&T offers..
Then accept terms of Samsung EULA (and hit No Thanks below)...unless you want to share information with Sammy.
Then you can put your name (I didn't), it' s up to you.
Disable the 3 checkboxes for location services (you can enable this later).
Then skip the Samsung Account creation and hit also Next on my "Find my mobile" screen without doing nothing.
Finally, you'll reach the Android Desktop.
Setting the stage for rooting with KingRoot
Still avoiding any conection to the internet, go to your apps and tap Settings.
Before doing nothin, I strongly suggest you change your language to english in case you use another.
If your first language is English, you're good.
If it's not, you can change it on General TAB, then "Language and Input".
After this, tap the Device tab, choosing then Display option on the left.
Choose Screen timeout and select 10 minutes.
Now select Lock screen on your left and Screen lock on your right. Tap "None".
Now go to "General" tab and tap "Security".
Enable the Unknown sources checkbox and press OK on the popup.
Press home button. Now you can connect to your Wifi.
The moment you got Internet, Samsung will start forcing some updates on your tablet.
At the same time, several Google popups will ask you to "regularly check device for security".
Decline them all the time!
There is a "Games" app that loves to open itself without asking
When that happens, it will introduce you to an agreement that you will REJECT.
If it doesn't show, better. But it will eventually.
Now enter the Play Store and Log in with your credentials.
Accept the playstore conditions when prompted. If you are kicked out of the app just enter again.
Still inside Playstore, now swipe from your left side border to gain access to the menu.
Tap "My Apps" and use the "Update All" button on the right.
Accept all APP Permisions (seven times in my case).
The update process will start. This will take some time so BE PATIENT and do nothing else.
When everything is updated, you'll notice some warning on your status bar.
Swipe down your status bar. It will ask several times to Update Google Play Services.
Tap any of update offers for Play Services. Playstore will open again offering the update.
Hit Update and Accept. When the update of Google Play Services is finished, hit the Open button.
You gain access to Google Settings. Tap Security.
Disable "Remote locate this device" - "Allow remote lock and erase".
Disable also "Scan device for security threats" and "Improve harmfull app detection" (unless is greyed out).
Hit the home button and go back to desktop.
Installing KingRoot
For the next step, you need to download these files on your PC:
* Kingroot V4.90
* RemoveKing
Copy them on your tablet's internal memory. Specifically on the root of your internal memory. If you copy them inside a folder, later commands will fail.
Back to your tablet's desktop, look for the folder icon on the bottom left corner. This will open the Samsung File Manager. Look for "Device Storage" on the left column. If you copied the files correctly, you'll find both on the right pane of the display. Extract the RemoveKing.zip file by tapping it and clicking "OK". A RemoveKing folder will appear on the root of your filesystem.
Now open the Kingroot V4.90 file. Hit Next and then Install.
If a google warning appears citing - "Installation blocked". Hit "Install anyway" (unsafe).
If it doesnt, just hit Open. A blue screen shows up with the legend "ROOT auth".
Swipe upwards twice (assuming you're holding your tablet in portrait).
Now hit the "Try it" button. The app will verify root status in a matter of seconds.
Now tap the "TRY THE ROOT" button at the bottom.
When the root is sucessful, you'll be asked to "Forbid Knox".
Tap Cancel and press the home button. Now you are rooted with Kingroot.
Installing and preparing Terminal Emulator
Now that we are rooted, enter the playstore and install the app "Terminal Emulator for Android". Open it. You'll notice some small font selected so, hit the 3 dots on the right upper corner and go to preferences. On Font Size choose 24 pt. Hit the back physical button of the tablet. Now the "white letters" become readable. And it shows something like:
Code:
klimtlteatt:/ $
Next type the following and hit enter:
Code:
su
A Kingroot popup will ask for root permission. Tap "Allow".
Now the $ symbol will change for #.
Next you hit the HOME button to exit the app briefly (don't close the app in any other way, just hit the HOME button).
Uninstalling KingRoot
After that, go to your apps and enter the KingRoot app.
Now tap the 3 dots on the upper right corner and select "General Setting". Disable "Smart Authorization", then disable "Enable Root Authorization". Finally choose below "Uninstall KingRoot". Hit Continue. Uncheck "Backup Root" when prompted and hit OK. When all is over, you're back to the desktop. Go back again to your apps and uninstall Purify.
Applying the Scripts
Open again Terminal Emulator app (thru the app Icon) . Now we need to hit a couple of scripts by moving first to our extracted folder by entering the following command on the terminal (plus enter):
Code:
cd /sdcard/RemoveKing/
To run the first script type (then press enter):
Code:
./step0.sh
It just takes 3 seconds, then type the following and press enter:
Code:
./step1.sh
This last script will ask for a confirmation during its process.
Type just an "y" and hit enter: (WARNING, the Y won't appear on your display after typing it)
Code:
y
You'll notice a bunch of errors, don't mind them.
Installing SuperSU
Now hit the home button and go to the play store.
Search and Install SuperSU (free version). Open it. Choose Expert.
The app will ask "The SU binary needs to be updated, continue?".
Hit Continue and then choose "Normal" when asked on the next popup.
You'll receive an "Installation Sucess!". Tap the Reboot option.
Congratulations! You are now rooted with SuperSU.
After rebooting, enter the Terminal app once more, and tap the X on the right upper corner and hit OK.
That will finish the current terminal session.
If you're interested in getting Xposed Framework, go to part 3 of this guide.
If you're just interested in debloating the SM-T707A and improve its performance, go to part 4 (Soon).
Part 5 is where I discuss the modules I'm using on Xposed and also some Playstore apps to improve functionality, and remove as much Touchwiz as possible, while also working on better battery life (Soon too).
Final Considerations (suggested reading - not mandatory)
While this guide may seem easy to carryout, it took me almost a month to get SuperSu to work on Lollipop.
I'm no coder (a soon to be Certified Public Accountant), and the real magic to pull this off was to try many combinations of different app versions, different situations with google services and several strategies with the script and superSU. In fact, most of KingRoot versions don't work on this tablet to get root, also tried SuperSume app from the playstore. The same could be said for KingoRoot (don't confuse it with KingRoot), it worked but I couldn't remove it without losing root.
Why I'm telling you this? Because using KingRoot and similar apps to root this tablet, your mileage may vary while doing it. In fact, even while applying my first two guides there's a respectable chance of KingRoot tool failing to root your tablet. If you followed this couple of guides to the last comma, your chances of success are very close to 100%. But I have noticed in similar Galaxy Tab S threads, that the use of KingRoot and KingoRoot to achieve root is just a matter of using the root tool many times until it works, and I wanted to avoid you guys going thru that. To take sucess rate as close as it gets to 100%, we took all of this steps. They were included to avoid many failures. I believe they're are 99% flawless to achieve root on Lollipop with SuperSU.
Also, the second script won't remove many KingRoot files, because it was thought for KingoRoot on KitKat.
I have to give myself more time to develop something that could really clean up the last traces of KingRoot.
Special Thanks
* @chixvicious - For showing how to achieve the same over KitKat and KingoRoot instead.
* @bakageta - For creating these scripts for the Alcatel smartphone over KingoRoot.
* @Kingxteam - For developing KingRoot to allow us to root our device.

Oh wow, I had forgotten all about those scripts. Glad to see someone getting some use out of them.

Broken links?
First and foremost, thank you for the thorough walkthrough.
I've come across an issue with the provided links to KingRoot and RemoveKing. When I click on either, I receive the following message:
"Invalid Attachment specified. This can happen for a variety of reasons-- most likely because the thread or post you are trying to view has been moved or deleted. Please return to the forum home and browse for another similiar post."
Do you have any alternate links available?
EDIT: I did find an alternate method that worked for proper replacement of KingRoot with SuperSU. All good, and glad for the compatible xposed framework.

I hope to get part IV and V in no more than 10 days...
I'm in the process of testing removing/freezing many services, just a sneak preview:
So far I was able to disable close to 180-190 apps/services from a total 250-260 (can't remember the exact number).
Of course there are some key services removed (for e.g multi windows, but that's just one service).
Still you can easily remove like 165 without losing any stock functionality. That's how much bloated the tablet is.
Removing useless stuff from samsung and 3rd party (eg. VPN, Policy Updates) or more evident like MultiWindow, the gallery app or even the file browser.
Or the weird ones like the phone app that is hidden and you can't use (you can disable it and still keep LTE Data).
More to come.

Need Help - Having Untimely Reboot Issues
Wow...Thanks SO MUCH for this guide! It gives me hope that I can actually enjoy using my T707A to the fullest!
Alas, I need some assistance PLEASE:crying:
I'm following your guide to the letter, and I've successfully achieved Part 1. Part 2, however, alludes me even after many, many tries. Here is what is going right and wrong:
a) Achieved root with KingRoot
b) installed and achieved SU with Terminal
c) ISSUE - KingRoot (or something) reboots the tablet during Uninstall, which kills SU access obtained with Terminal
d) ISSUE - after reboot, I no longer have permission to run the scripts to uninstall KingRoot
Is there another way for me to do this? As long as the tablet is rebooting during uninstall of KingRoot I have no SU access, so can't do anything but start over and experience the same thing time after time.
ANY assistance would be so very much appreciated...MOST humbly & sincerely...Tom

Where did you find the alternate method??

Hi...I am VERY interested in your "alternate" method for replacement of KingRoot with SuperSU that actually worked. Would you be so kind as to share that with me?

I had that problem many times, the uninstall reboots the tablet before you can establish SuperSu.
The most reliable way I found of overcoming this is to follow the exactly in this order and without stopping to much because google wants to run updates behind scenes that mess with our process (that's why sometimes it works and sometime it doesn't). My recommendation is to start over from scracth again (I know it's boring). I'll probably do it again on my tablet just to validate and to try some other things related to the original services).

Nougat Plugins for Tasker

I've recently upgraded to Nougat on my rooted phone and wondered how best to replicate my old Tasker profiles that were reliant on Secure Settings which appears to no longer work on Nougat (it says it cannot find root)/
The main functionality i want is the ability to turn on/off:
Airplane mode
Location Completely (when screen off)
GPS when opening apps that use maps
Mobile data
Can anyone suggest the best way to get this functionality back if its possible?

You could try some of the run shell commands from this thread https://forum.xda-developers.com/u/tasker-tips-tricks/best-run-shell-commands-tasker-t3419204 or use the AutoTools plugin https://play.google.com/store/apps/details?id=com.joaomgcd.autotools

Majority (if not all) of Secure settings stuff is now easily available on AutoTools.

Thanks, just installed it and playing around with it and when i try to run a task it tells me 'No pemission to change settings' i see the adb command being talked about. Do i have to run that even though i'm rooted or do i just have something configured wrong?

You can replace Secure Settings with SecureTask plugin. Free and it works great.

Simply better. First of all it's free. In addition it has a lot of features like sync settings, failed login monitoring, settings monitoring, change pin/password, log information, data usage and much more, nothing comparing to automess.

Hi, I'm in nougat with a ROM but I can't open tasker. I hope anyone can help

@farquea,::if you want to stick with securesettings in noughat,here is the work around i am using, found the fixfrom superSu forum..
Obviously i am using superSu to give root access for secure settings..
First flash superSu in systemless mode in twrp.
After reboot, using terminal emulataor type the following command
su
echo "BINDSYSTEMXBIN=true" >> /data/.supersu
and reflash superSU from twrp..securesettings will be enabled...

Tasker cannot detect root with MagiskSU. If you attempt to select the Use Root option, you get a toast: "Error, you device doesn't appear to be rooted." However, as mentioned here, if you preface a Run Shell command with /sbin/su -c, Magisk Manager will prompt to allow Tasker root access and your command will work.
Code:
/sbin/su -c "svc data enable"

Well. Original position:
- Used RR April 16, 2017 nightly build as fresh install
- recovered Tasker from TiB backup
- created new task
- to avoid cheating assumptions created Tasker's task shortcut to run the task.
Video link is below. Pay attention to LTE symbol in the beginning of the vid. Task's goal was to disable it. The task was run via desktop shortcut
https://drive.google.com/file/d/0B8jDZdXO_06aMW5GYVJIRjBfemM/view?usp=drivesdk
Arrgh.just saw - LTE link run down before the task run - Tasker spotted my homecells and tried to setup WiFi connection (but no WLAN settings were restored). Nevertheless, it changes nothing - Task call via shortcut didn't call any root complaints, did it?
P.S. no offences again. In the cast i've intentionally shown Magisk's superuser tab to demonstrate nothing but two apps had root access. But after restore Tasker asked for 'su' perms (baloon), and was granted. Maybe, skipped 'su' perms for Tasker is Your headache?

Sorry for late reply. Could it be so that Tasker was asking for root permission, but was not granted? Also, guess, You've checked that Tasker is in Device Administrators?
Upd. Stupid assumption. You've said , the task works when running on its own, from Tasker, but pops up the warning, when 'Use root' is checked... Not a big specialist in Magisk, but, haven't You use something like 'Hide root from apps' or alike in Magisk?

[GUIDE][GLOBAL]Flyme 7 update,Disable system apps,Enable night mode,Weather fix

First of all i highly recommend you update your phone to latest version of Flyme as of day i write this guide newest stable version is 7.0.0.0G. It brings various bug fixes as well as security update and new functions. It fixed the weather problem too when it would not appear on secondary screen. This is my experience based on the standard model with Helio P25 chip.
JUST IN CASE BACKUP ALL OF YOUR DATA FIRST
Grab it at http://www.flymeos.com/firmwarelist?modelId=88&type=1
Installation is pretty straightforward:
-switch off your phone
-now press volume up button and power button at same time, then release power button when meizu logo appears
-phone now will enter update mode, connect it to pc and it should show up as removable drive named recovery, copy the update.zip over it
-once copied tap the start button to begin. the process itself and first boot will take a while
-when done and phone boots up just log in to your accounts and set up everything as normal or whatever
ta-dah ! you should be running latest software now.
Next problem i've encountered was big number of unwanted apps and you will need working ADB for that. I've always used custom roms which did not contain bloatware. Now im giving you one of the way of disabling them (not permanent removal).
For this to be done you need to activate developer mode and usb debugging, simply go to settings->about phone->and now tap on your build number several times
After you activate it it will be available in accessibility options under developer settings. just check the usb debugging and you're good to go
DISCLAIMER: dont ask me about adb drivers for your phone, since i had issues installing them under win 10 x64 build 1803 i thought "aw f*ck it" and just did it on linux where everything worked out of the box.
The application you will need is called Ice Box (you will find it here https://play.google.com/store/apps/details?id=com.catchingnow.icebox&hl=en_US) and install it.
After you install the app its necessary that you remove ALL of your accounts including your Google account. We will need to grant the app device owner permission. Also if multi-user or guest mode has been set on your device, it need to be closed or deleted.
When you have that done just type in your command line , terminal or whatever "adb shell dpm set-device-owner com.catchingnow.icebox/.receiver.DPMReceiver "
Now reboot and add your accounts back, and disable/freeze uwanted apps.
Last - the night mode. As its no longer availble in Flyme 7 if you want to use it you need to manually bring it back by installing Flyme Lab and enabling it trough quickshortcutmanager. Install both apps, then open quickshortcutmanager and search for Flyme Lab. expand it and choose the activity named com.meizu.flymelab/com.meizu.flymelab.component.nightmode.NightModeSettingsActivity .Create shortcut and open it. You should be able to enter the night mode.

Nice guides, thanks.
It's also nice that Flyme 7 still supports rooting, therefore I'm using Titanium Backup to freeze unwanted apps. I bought it when I was using another phone so, for me, it's still worth it. Altough, for uninstalling system apps I'm using separate ADB commands for each app.

Its first time for me writing a guide so good word is always appreciated. What im trying to show here is the no root way of getting rid of apps for ppl like me who dont want to root their phone. As i bought it literally two days ago and i dont want to mess with it too much and loose warranty or/and OTA updates.
I also been considering posting a root guide once i tried it myself to confirm it working.

Well, before I discovered a rooting method for Flyme 7, I used to uninstall apps by using ADB commands. So, yes, it is possible to remove unwanted system apps without root. But now, after rooting Flyme 7, I'm only using Titanium Backup to freeze unwanted system apps, not removing them.
As far as I know, rooting Meizu phones by the official method (from Settings) does not lead to losing warranty. Only OTA updates are lost, but this is not important, at least to me, because I can always check Flyme website for new updates and, if I want to update, I just download the file and flash it through standard Flyme recovery. There is no need, for me, to maintain OTA capability. Anyhow, Flyme updates are slow to non-existent, so we can't really complain about losing an update.

Thank you all. I'm happy with this phone at all, but software has few shortcomings and design flaws, in my opinion. Especially related to the integration with "flyme login" and Touchpal. This last one is very annoying because although I try to stop it, at each software update it comes back, more annoying than ever. So, I have some questions: which is the adb command to stop and freeze bloatware without rooting? Which is the official way to root the phone? Once rooted, is it possible to revert to the unrooted state? Some apps, actually, do not work on rooted phones. Thanks

I can't freeze (or disable) apps with ADB commands, only uninstall.
You need [email protected], App Inspector or similar (to find exact name of package for an app) and these commands:
adb devices
adb shell
pm uninstall -k --user 0 name_of_package
Example, for gmail:
pm uninstall -k --user 0 com.google.android.gm
Regarding rooting, as far as I know, the only method that works on Pro 7 / Pro 7 Plus is also supported by Meizu (but it breaks OTA updates).
The method is described in this video (in russian) but it's quite easy.
If you want to remove root (or if root breaks functionality) you have to reflash the same ROM from Recovery (without wipe).

Any air update coming soon? Or manually installation single option?

Question Okay, I'm stupid...

So, I was going through and removing bloat from my phone and was trying to remove the Samsung Contacts app through `adb`, but apparently I removed the wrong thing and now the Phone, Messages, and Contacts app are crashing every time I try to open them. I removed "package:/system/priv-app/SamsungContactsProvider/SamsungContactsProvider.apk=com.samsung.android.providers.contacts" which is apparently a core service. I'm wondering if anyone might know how I could reinstall that APK?

install this apk should solve the problem

If worse comes to worse a factory reset will.
A lot of the bloatware is useful. I prefer to use a package disabler as I can easily toggle them on or off as needed real time.

It sat for a minute trying to install and then came up with, "App not installed" and says that every time I retry.

Trying install via adb I get: "
Performing Streamed Install
adb: failed to install /home/mhicks/Downloads/SamsungContactsProvider.apk: Failure [INSTALL_FAILED_DUPLICATE_PERMISSION: Package com.samsung.android.providers.contacts attempting to redeclare permission android.permission.SEND_CALL_LOG_CHANGE already owned by com.android.providers.contacts]"
Hmmm, perhaps I should remove Google Contacts first...

Okay, that helped, but now I'm getting: "
Performing Streamed Install
adb: failed to install /home/mhicks/Downloads/SamsungContactsProvider.apk: Failure [INSTALL_FAILED_VERSION_DOWNGRADE]"

I thought deleting the "com.samsung.android.providers.contacts" might solve the problem, but trying gave me: "
./adb -d uninstall com.samsung.android.providers.contacts
Failure [DELETE_FAILED_INTERNAL_ERROR]"

try these commands on pc
adb shell cmd package install-existing com.samsung.android.providers.contacts
adb shell pm install -r --user 0 /system/priv-app/SamsungContactsProvider/SamsungContactsProvider.apk

The first command returns: "Package com.samsung.android.providers.contacts installed for user: 0", but the second command returns: "Failure [-3001: INSTALL_FAILED_REJECTED_BY_BUILDTYPE]"

If you have deleted the apk with root you just have to paste it again in the folder /system/priv-app/SamsungContactsProvider

It is somewhat complicated to recover the device without wipe in the past I had these problems, it was solved with a higher version of the application

@rtd4, I suppose it's time for a wipe... Thanks for trying to help me.

If you had made a copy of all your apps including system apks with ApkExport you could now use that copy to restore it.
Now before you factory reset make a copy of your installed apps and any system updates then save it on the PC or SD card. After the reload you won't need Playstore. It speeds things up a lot...
APK Export (Backup & Share) - Apps on Google Play
Manage and extract your apps.

@blackhawk, thanks for the tip. Right now, I'm trying to set up a Telegram account so I can root my phone (US version) if I'm going to go through the trouble of wiping. Unfortunately, Telegram's SMS verification appears to be broken or at least doesn't like Mint Mobile... Fun day.

You're welcome.
You really don't need to root.
Consider the possible consequences carefully.
Package Disabler will easily block apks you don't want running.

Well, it would appear it's moot anyway since I'm at Baseband v4 and only v1 can be rooted apparently...

This is the one I use:
Home - Package Disabler
The only NON-root solution that let’s you disable any unwanted packages that come pre-installed / installed with your phone / tablet.
www.packagedisabler.com
It has an interactive widget that allows you to toggle selected entries on/off. It runs even in Safe mode so be careful what you disable. I've never had to do a factory reset because of it but the potential is there.
Unfortunately it no longer disables Google play Services but will disable all carrier bloatware including OTA updates.

Then how come you have removed apk from system?
In case you have used command like
pm disable packageName . Then try pm enable packageName
Or
If you have used
pm hide packageName then try
pm unhide packageName
