[How-to] root, the more easy way

hi there,
finally i found a more easy way to root my z3tc.
it works with out flashing an other firmware and it keeps the drm keys and your bootloader locked.
its not even necessary to wipe the device, so you can keep all our apps an settings.
so here are the steps i did to get root on my z3tc running the latest kitkat stock firmware.
1.) download and install kingroot 4.1 its an oneclick root, similar to towelroot.
take care that it is v4.1+ and not below !!!
2.) install superuser from playstore (just because you well be asked for it in the next step. i use kinguser for granting permissions later)
3.) download an install XZDualRecovery
(choose option 2, install for superuser.)
4.) download and flash (via recovery) SonyRICDefeat
enjoy full root on your device

nvm

i concur with TS.
But be warned that kingroot's SU binary sometimes have issues with granting access to ADB even though you have allowed it by default.
I spent the entire day troubleshooting my friend's tablet trying to root via kingroot,flashing dual recovery and giving it proper root via supersu. needless to say, it was very educational as it was frustrating.
once you ran the bat file for ric defeat, you still need to dl the app called SDfix (by nextapp) to fully write to sdcard. and yes, the sdcard write bug is still there from kitkat!

Hi There,
Does this Method work with Lollipop?
Is it possible to use Supersuser instead of Kinguser to mangage permissions?

Yes works with Lollipop. After running the latest Kingroot (KingRoot-4.1.0.249.apk ), before rebooting I installed dual recovery for locked bootloader. Then rebooted to TWRP and flashed BETA-SuperSU-v2.49.zip, which will uninstall KingUser on first run.
However I got the XignCode3 error from com2us and gamevil games. So I booted back into TWRP and flashed UPDATE-SuperSU-v2.46.zip and everything was peachy.

is there a special reason why you flashed supersu v2.49 first and v2.46 afterwards? i mean flashing just v2.46 would work as well right ?
@frostmore did you use 4.1 ? as far as i understood ric defeat gives you write access to the system on the internal storage on sony devices (for what normally root would be sufficient) and has nothing to do with the kitkat writing limitation on external cards. so you have to use one of the many apps in the store which will fix this. (or do the trick yourself in an xml file) since i installed xposed as well (this was btw the only reason why i wanted root to be able to use app settings again) i did it there.

It works !!!
Finally. Thx a lot.

Worked great on my SGP611. I didn't bother unlocking the bootloader. I performed this on 23.1.A.0.690. I first replaced with SuperSU 2.46, but it seemed to have issues removing KingRoot. I then flashed 2.49 beta, and it removed KingRoot, then I switched back to SuperSU 2.46.
Cheers!

I tried rooting my SGP611 with Android version 4.4.4 and failed. That is when I decided to manually update (flash) it to 5.0.2 with the build number 23.1.A.1.28 (currently the latest version Sony had released). And suddenly the magic happend thanks to KingRoot. On the first try I have successfully rooted my device.
Then, without rebooting, I immediately installed NUT's XDualRecovery via the second method (install on stock modded ROM with superuser).
Next thing I rebooted into TWRP recovery and flashed the latest available BETA version of SuperSU by Chainfire (2.49-BETA).
I rebooted back into system and opened the SuperSU app and removed all the KingRoot apps, updated the 'su' binary with 'Normal' mode in SuperSU and finally rebooted my device again.
The result was satisfying.
At last I have root access on my Xperia Z3 Tablet Compact 16GB Wifi model running Android 5.0.2 with Chainfire's SuperSU, XDualRecovery, Bootloader locked!
I tried RIC defeating my device and wasn't successful. But apperently that's not a big deal because XDualRecovery may have already killed RIC. (Maybe I am wrong(!), so please correct me...)
My favourite apps like AdAway, Titanium Backup, SD Maid and Busybox work flawlessly. And rebooting my device didn't remove my root for now. Well, I have to test it for some days to see if root is permanent.
A big THANK YOU to the KingRoot team.

I tried Rooting my SGP 612 with stock 5.0.2 but got stuck at the first step. Kingroot couldnt root the device succesfully.
Edit: Dont mind the commenct, worked fine on the second try.

hey guys rooted Z3 Tab with Kingoroot..
on the last step i install Supersu 2.49 and install the binaries...
but on the last step install Supersu 2.46 but after reboot
can't install the Supersu Binaries?
Anyone have s a idea for me?
Regards

This method still works on 23.1.A.28

i can't root my SGP621 with kingroot 4.1 :crying:
it says "root access is unavailable"
it's on Lollipop 5.0.2
thanks guys

sir, can i root the sameway ?
@stavro this is my device info...thx

i am not the developer of the root method nor do i have experience with rooting (via kingroot) of other devices then mine (sgp611).
its just a list of things i did to get root in a more simpler way then it was already possible before.
i would expect that it works for the sgp621 too since you have same firmware version then i have.
but if you are not sure you better go to the general kingroot thread and see if other people can confirm that root is working for your device.

Do I have to flash XZDualRecovery and SonyRIC Defeat when I only need root?

No issues at all even starting from Lollipop 5.0.2 v23.1.A.0.690 firmware, thank you!
The only thing I can't do is flash RICDefeat patch from recovery (it fails with an error I can't remember), but even without that patch I can read and write \system folder.

It's highly recommended to install
XZDualRecovery to automatically gain the RIC patch. You don't need to flash SonyRIC Defeat if you install the recovery because it's already included.
The question is, what do you want to do with root? Having system R/W access is quite important to actually have a complete root experience.

Bricked Lenovo A8-50F. Need Help with SP Flash Tool

Here's the situation:
I have a Lenovo A8-50F table. After attempting to flash a new TWRP recovery rom on it after unlocking the bootloader, I ended up with a tablet that would constantly reboot. I am attempting to fix this issue with the SP Flash Tool but I have two issues:
I don't know if the MT file is the right file for this.
You are supposed to see a red bar pass when you hit download indicating it has finished the upload and it never comes.
I have done the volume up + voume down + down and all the other combinations and at most what it produces is a 2005 error.
I have the a58p rom in zip file that I downloaded from here.
I'd like to have some help, but I'm not sure what I'm supposed to be searching for.

Hi, I know to recovery you Lenovo A8-50F. It's yet actually?
Thanks.

I used KingRoot (ver 4.8.2) to root my Lenovo Tab2 A8-50F Tablet.
I used KingRoot as part of a SuperTool. The SuperTool, using a batchfile script, also removed KingRoot after the tablet was rooted and then installed SuperSU.
The SuperTool (April 6, 2016 version) was created by xda's RootJunky for the Amazon Fire 7 5th gen tablet, using KingRoot and SuperSU, but it rooted my Lenovo Tab2 A8-50F Tablet, uninstalled KingRoot and installed SuperSU, all with only a couple of mouse clicks.
Even if you are already rooted with KingRoot, you can use this tool to uninstall KingRoot and install SuperSU. (Just run the tool, let it re-install KingRoot, don't run KingRoot but hit Enter on the SuperTool to then uninstall KingRoot and install SuperSU).
Lenovo Tab2 A8-50F Tablet info:
Model Number: Lenovo TAB 2 A8-50F
Android version: 5.1
Kernel version: 3.10.65
Build number: A8-50F_S000037_151023_ROW
Software version: A8-50F_151023
Hardware version; LenovoPad A8-50F
The SuperTool batch file script rooted the tablet with KingRoot and then uninstalled KingRoot and installed SuperSu.
I have since installed ES File Manager, Titanium Backup, Link2sd on the tablet. Root is totally working. Rooted with only a couple of clicks!
Just enable Developer options on Lenovo Tab2 A8-50F (by tapping tablet Build Number 7 to 10 times [Settings, About Tablet, Build Number (tap 7 to 10 times)]), enable USB debugging on Tablet in the Developer options settings.
Connect Tablet to Windows 10 with a USB data cable (I used the USB 2.0 port). When screen message on the Tablet mentions connections, make sure it is in the MTP mode.
Extract RootJunky's SuperTool Zip file to the Windows 10 desktop.
Run RootJunky's SuperTool (Amazon-Fire-5th-gen.bat) You may have to read the instructions on the pages below and install adb drivers. Pick option #6 Root. Choose Option #3: version 5.1.2. This will run a script that installs KingRoot, allows you to run it manually, and then removes KingRoot and installs SuperSU.
Press enter and KingRoot will be installed on the Tablet from the SuperTool. (approve any messages that appear on Tablet screen) Now don't touch the PC SuperTool until the Tablet is rooted.
Open KingRoot on the Tablet and run it. You may have to run KingRoot several times and the Tablet may reboot. Just keep running KingRoot until the Tablet is rooted. After KingRoot reaches 100%, then press ENTER on the PC.
The SuperTool will now uninstall KingRoot and install SuperSU on the Tablet.
Choose NORMAL SuperSU install on the Tablet when prompted. When SuperSU is installed, reboot the Tablet. Disconnect data cable.
After reboot the Lenovo Tab2 A8-50F Tablet is rooted. There will be a request by SuperSU to upgrade. Approve it. You can now install Titanium Backup, Link2sd, ES File Manager, etc. Your Tablet is rooted. As easy as that. THANKS ROOTJUNKY!!!

S4 Question - Messed up root

I used towel root to root my S4, and I somehow allowed an auto update, which downloaded the updated, tried to install but failed. But I lost my root.
I am running 4.4.2 - Kitkat right?
So I don't have root, and I cannot update my phone - Is it possible for me to root it again? If so is there a link to instructions?
Thanks in advance, the DoridForums people sent me here -

I dunno what you are running.
1. You can take a look in your Settings - About device (Pic attached).
2. Try again Towel Root if you still running android 4.4.2 for root again your device.
3. Tell us how it works.
* You can download OTA udpates but you can't install them when you are rooted. Root your device modify system. It changes of OFFICIAL to CUSTOM. OTA detects it and give you a error when you try to install the update.

Ok attached is my about phone info -
I just tried towel root again, and it says this phone is not currently supported. So again, thought I would see what my easy options might be.
I can't post an image or links, Android version says 4.4.2 - If that's what you need? If not let me know which number you need

Use CF-Autoroot to root instead of Towelroot. While CF-Autoroot requires the Odin software to use, it's far more consistent in its results since it temporarily replaces the existing recovery with a recovery that will install SuperSU into the /system partition. Unlike Towelroot, CF-Autoroot is version agnostic, meaning it will work regardless of the version of Android installed.
There is an entire thread on CF-Autoroot. Hit the search bar at the top of the page and I'm sure you'll find it.

Running out of options trying to root SM-G530T

I've been trying to root my GP using the KingRoot and Odin methods, but came out empty with both methods
Summarized attempt
- Installed the newest KingRoot apk into my phone and installed
- Gave me an "Could not find root but try anyways" error and processed
- Finished successfully and confirmed root with Root Checker
- Ran SuperSume Pro and it stalls
- Reset phone and it bricks (infinite T-Mobile opening loop)
- Factory rest using Odin and stock firmware (from samsung-firmware)
- Try using pre rooted firmware (CF Auto Root Fortuna3a and another firmware I found) after, but both failed during the Odin process
If anyone would like me to go into more detail about my attempt, help me through a process, or link me to another root solution I would greatly appreciate it

I don't have the same model of grand prime, but I'm pretty sure you could just flash supersu.zip then install supersu.
Maybe wait until somebody else can verify I'm right, but I'm pretty sure it works on other models. You can find it along with other info here in the forums.
Hope it helps!
Edit; reread your post and had an idea, how about using the kingroot apk to root, verify with root checker, then try supersu or Super User from the app store?
Doubt it could hurt, if root checker is saying you have root, then it'd be safe to deduce that it's the rights management app and not the root process itself that's the issue

Here this is how I rooted my g530t http://forum.xda-developers.com/grand-prime/development/kernel-root-root-sm-g530t-5-1-1-t3203476

I figured out it was the Google FRP Lock that was the cause of the problems lol, after turning on the OEM unlocking (found in the Developer options in settings) the root worked fine using the TrapKernel MD5 with Odin

[T-Mobile D6616] Updated Root Method Request

Good afternoon,
After MUCH research, I have arrived at the conclusion rooting the D6616 with T-Mobile's likely final Z3 build for 5.0.2 (Build 23.1.C.0.399 and, really anything past KK) is no longer possible without involving Kingroot.
Why does this matter? Because there may not be a feasible way to remove the most recent builds of Kingroot from the D6616 ROM. Using Kingroot's own uninstaller in the App settings fails and factory resetting using the ROM/stock recovery threw my phone into a bootloop. Other users report it successfully factory reset their ROM with kingroot installed as a system app and their device no longer rooted. I attribute the variety of outcomes to different software builds and Kingroot versions.
It seems as though the only working root method also uses ZXDualRecovery. Though I have not tried it, all procedures that show the ZXDualRecovery method of pushing recovery and superSU involved rooting the device with Kingroot first and removing it after SuperSU is installed. This appears to be the only still-working method of acquiring temporary root long enough to install recovery. The only way to remove Kingroot is to use flashtool and a new Sony TFT, which also removes root and recovery.
Has anyone successfully been able to pull off rooting a D6616 lately? I want to keep this phone but it is unfortunately useless to me without working root so I'll likely be returning it if nobody still has one that's running the last software with a locked bootloader.
I would really appreciate any help anyone can give.

I believe I have done it! I think SuperSU is ever so slightly ahead of Kingroot.
What I did:
1) Rooted via Kingroot app on Google Play. Run rootchecker after it's done its business to make sure. DO NOTHING ELSE IN THE APP. Doing so may prevent SuperSU from kicking its ass later.
2) Downloaded and upacked to desktop the file for Xperia Z3 from here:
http://nut.xperia-files.com/path/XZD...ecovery_2.8.26
Z3-lockeddualrecovery2.8.26.-RELEASE.combined.zip
3) Disabled antivirus
4) Installed USB drivers via Windows 7 plug-n-play. Unplug phone.
5) Downloaded SuperSU recovery flashable zip from here:
http://www.supersu.com/download#zip
6) Ran install.bat from extracted ZXDualRecovery zip
7) Enabled developer options in phone, enabled USB debugging, revoked USB devices, rebooted phone, plug in phone.
8) Connect Phone, wait for device to register in windows.
9) Okayed communication from PC.
10) Place in USB Install Mode on phone.
11) Choose option 2 to install to device rooted by SuperUser. Kingroot has blocked option 1 (old method)
12) Enter TWRP (Automatic) and go to Backup, check all boxes, create Nandroid by sliding the slider
13) Reboot, ensure phone boots. Put SuperSU.zip on the external flash drive. Go to your new App: NDR Utils. Choose TWRP as Primary Recovery. Choose Reboot to Primary recovery
14) Flash zip for SuperSU. DO NOTHING ELSE. Do not wipe cache, do not fix permissions. Click REBOOT.
15) Launch SuperSU App. Attempt to update Binaries. It will not, but it will detect Kingroot, and somehow can get rid of it itself using onboard capabilities. It will do so and update binaries.
16) Reboot (Automatic via SuperSU)
17) Check to make sure SuperSU binaries installed by launching the app.
18) Reboot to recovery using the steps from step 13) above.
19) Create another backup using step 12) above
20) Reboot and DONE.
To the best of my knowledge, nobody has indicated how to do this in a clear Step-By-Step for the final build of this ROM. So because I've troubled you all for small chunks of the process I figured I would.
This applies to T-Mobile's likely-final software release for the Xperia Z3 android 5.0.2 on build 23.1.C.0.399.
DISCLAIMER TO ANYONE ATTEMPTING THIS: It appears Kingroot is "onto" what it is being used for. Given the behavior of this application, there is no reason for anyone to believe it is not a malicious program, but it is a necessary evil for this purpose. Newer versions of SuperSU are capable of removing Kingroot on their own, but alternative methods may be necessary. I attempted an earlier version of SuperSU and it was incapable of removing Kingroot.
It might remove via debloater. This is the only way to remove the system apps on this phone reliably, so you WILL need it if you intend to keep the bootloader locked. I couldn't get any root-enabled appstore app to do it including ES File explorer and Titanium Backup. It looks like you need a computer to remove system apps on this phone. Fantastic. Debloater works great though so don't be afraid to use it. Use the filter to search for Apps. You can remove them, but they will not be gone until you reboot your device. Hooray no more filecommander and lookout! Debloater can be found here:
https://forum.xda-developers.com/and...bloat-t2998294
Plug in your phone. Give it root access. Easy peezy.
Then Xposed current framework and installer:
https://forum.xda-developers.com/sho....php?t=3034811
Version 3.1.1 fixed the bootloop problem, so you shouldn't need the fix zip, or at least I didn't. But if you do, you can find it here:
https://dottech.org/187028/how-to-fi...-z5-z4-z3-tip/
Flash the framework for your device in recovery (arm) and then the installer APK from the ROM using a file browser.
FINALLY Youtube Adblock and minimized playback. SCORE!
I think that's about it. That's literally the best we can currently hope for from this device. I think there is an Xposed module to heavily alter the look of the ROM here but I have not tried it. Plus it only claims to work w/ 4.4, and we have 5.0.1.
https://forum.xda-developers.com/z3/...6#post71601966
For devicewide adblocking I use DNS66 since there are no proxy settings for adblocking on this device, unless I'm missing something. I really hope I am. This means there's no native adblocking.
Xposed modules worth using you can find by searching in the Xposed store: Blurred System UI (LP), Gravity Box [LP], RootCloak, Xperia/AOSP NavBar Buttons, Xperia Super Radio, YouTube AdAway, YouTube Background Playback. And of course DNS66 (PlayStore).
I have tinkered with the rest and find them of no value.

I followed the steps but SU didn't ask to update anything. It just opens up and everything is fine?
Then all I did was unistall kingroot(purify) and it looks like it's gone, but is it?

Just leaving this here, this is how I rooted on Android 5.0.2 with the D6616
http://nut.xperia-files.com/
Read the documentation that comes with the latest XZDualRecovery and flash SuperSU or whatever you want.

Were you able to install twrp without rooting first on your PC? It doesn't work for me. I did option 3, install on unrooted device.
Are you able to systemless root?

When I run the installation it fails at step 3 on the install bat.

Hi, a bit of an old thread, but has anyone had any success rooting the D6616 without using Kingoroot or Kingroot? Both are malware which are designed to not be fully removed and be as resilient as possible, and uninstall does not actually uninstall them...

Yes, the old method still works. Use the search feature. I'd just link you, but I"m busy at the moment.

i followed these steps, and have gotten to the point where you flash supersu and reboot, but i'm stuck in a reboot loop now. wanted to use this old z3 as a dedicated audio player, and needed to root for some audio enhancements...
edit: i did have TWRP for a minute, but now when i go into recovery it's the stock recovery again, with options only to continue booting, boot to safe mode, factory recovery or power down. the first two options return to a boot loop. can/should i attempt to use flashtool, or factory recovery? i don't want to accidentally wipe something i might need in the backup.\
UPDATE 10/19: I was able to get back to ground zero using Sony's xperia companion software repair. Flashtool 9.25 and 9.26 would never successfully install flashmode drivers, nor would it display the stock .ftf file.

this new method seems to fail for me on both of my old z3's. does the method you're referring to involve downgrading to 4.4.4? i've done some extensive searching of this forum (and the android development ones as well) but don't seem to be able to find any other info.
