Hello first i assume you already unlocked the bootloader so your warranty is already voided then you're already acquired root. If you downgraded to marshmallow via flashing the marshmallow firmware again through the flashtool app on the computer you have to start all over again rooting your device, but if you managed to generate a twrp backup prior running in marshmallow firmware then it's simple as restoring your backup through the twrp recovery interface.

Just find a MM ftf file on XDA or xperiafirm and use flashtool to flash it. No need to unlock bootloader (so it will not void your warrenty) and root is not needed to do it.

[Share] Root Xperia Tab Z LB/UB

Hey Guys,
i would like to share a new app with you. It´s called Towelroot. It roots your Device instantly.
Just go to http://towelroot.com and click on the lambda. Install it and click make it rain.
It Works!! No need for Recovery or anything else. Locked Bootloader AND Unlocked Bootloader.
My Tab Z runs the latest 4.4.2 so it works with the latest firmware.
Geohot (creator of towel root) says that it roots nearly every device. So keep on sharing.
Below i have two Screenshots for evidence.

wow!
I just can't believe!
It worked on jb4.3
Yes and also worked with my Tablet Z SGP351 4.4.2 stock Rom now Rooted
Worked for me too! I'd been planning on getting root with multiples flashes and manipulations for months but I kept postponing it... and now that 1-click hack took just a few minutes!
I've gone crazy with Xposed Modules and root apps that I'd wanted to use for ages. Next up will be finding out how to install a custom recovery; I'm used to flashing unlocked devices...
Works perfectly.. I recommend to use Superuser as su app after using this root app.
Great Stuff!
Hey it Worked! Now what's next Custom ROM?
Tablet Z SGP321 4.2.2 10.5.A.0.230
Thank-You works great ( XTZ 312 upgraded KitKat v4.4.2 via Flashtool v0.9.16.0)
If I root using this, will it void warranty?
I bought the LTE version tablet 2 weeks ago and don't want to lose warranty so soon..so, if I root using this Towelroot method, do I lose warranty as well? And I will still get/use official OTA from Sony?
If I need to, for some reason, can I un-root the tablet again and go to complete stock?
Pardon my limited knowledge, a n00b here.

I know that you loose Warranty when you unlock your bootloader. But only rooting it, is kinda difficult. I dont know exactly how the towelroot root affects the sony firmware. Maybe it wont void your warranty but maybe it will. I cant say it 100% but if you want to stay safe with your Tablet dont Root it. If you need and use what sony´s offering, keep using it without root.

[Q] Will a brand new Z3 be still rootable ?

Hi,
im looking at buying a Z3 at the weekend but the main thing is will it be still rootable? Im not sure what firmware it will come with
Are all versions still able to achieve root?
If so could someone link me to the best root method, much appreciated
I've bought a Z3 3 weeks ago and it rooted just fine. You do need to flash an older firmware

5.0.2 isn't rootable, at least not directly.
As long as we have root method for at least one fw available for device we can root all new firmwares.
So...it's not a problem to root Z3, no matter which fw was on it.
All you need is to downgrade to 4.4.4 (version that could be rooted), root it, install recovery and then upgrade by flashing prerooted ROM.
Z3 will retain root possibility as long as its alive...
Of course, all of that applies for locked bootloader.
If you want to unlock bootloader, you could root device by flashing kernel via fastboot...

thanks for the help, phone is coming tomorrow so it will be the first thing i do.
Coming from a nexus 5 so should be quite an improvement, especially battery life.
Another Question
is app2sd built into the firmware? or do you need a third party app which requires root?
things i need installed on SD card:
all games / apps including titanium backup PRO
can it be done?
If you get a new T-mobile Z3, you will not be able to root or unlock the bootloader.

Got Cheated with a Z3 Prototype Protected

i got more info from the other threads on this similar issue.

Model # D6603

i cant post images since new user
It is for d6903 not for d6603. And you cannot flash a pre-rooted ftf file if you have not rooted your phone before flashing. I think you should just flash the latest marshmallow ftf for d6603 and root you phone afterwards.

I'm pretty sure prototype protection is the apk that does that just delete it. Use kingroot to obtain root. find xz dual recovery theres actually an apk for it so if you found that and installed a prerooted zip you don't even need a computer becarefull what you are flashing if you flash the wrong stuff you could brick your phone.

Thanks for your reply.
You're saying that to install a pre-rooted Rom I should root first. Then install the rom.
Could you link me a good rooting software and flashing Roms?

I found a site which could Flash 5.1.1 W/O root using flash tools xperiafirmware.com, Could you tell me whether that method work ?
The best way is to flash kitkat and root with giefroot. 5.1.1 rooting methods by kingroot, sends your IMEI to an anonymous IP in China.
http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056 this is the common and safe rooting method. However, if you don't want to flash kitkat and stuff, you can flash Marshmallow ftf files(you can download them through Xperifirm) and root your phone http://forum.xda-developers.com/z3/general/wip-sony-android-6-0-mm-t3337357 with this method
Thank you Guys for your help ! i flashed Marshmallow ftf and the phone is smooth and got rid of all the Prototype issues. thanks again.
i just got one off ebay with same issue, I am unable to get it to fastboot or bootloader mode with vol buttons, very strange, and nothing when plugged in with USB, does not turn on or display in win 10, i loaded the usb drivers for it but still nothing...

[Completed] rooting issues

I have rooted and unlocked my bootloader in asus zenfone 2 laser Z00ld and tried to install a custom rom. But the rom didnt install so i had to install official stock lollipop 5.0.2 rom.
Now i am having problem with this rom. Hangs a lot. Battery drains too fast. Sometimes the front speaker gets activated while playing music.
So now I want to revert back to the factory rom that i got at first.
1. Is it possible to get back to the official rom????
2. is it possible to get the official software updates from company after relocking the bootloader and unrooting the fone???
I am not a noob. But i am just scared of doing the unrooting process as already i hardbricked an yureka plus which was just 2 days old.
So anyone please help me with the solutions.. :crying::crying:

Greetings and welcome to assist. I'm not sure where you would get the original rom from but yes you should be able to return to it and once you are unrooted you should be able to take ota's
Good luck

How to update rooted Galaxy Note 20 Ultra

Hey all,
I am new guy using note20U. i have rooted my phone successfully (snapdragon version ) i am just confuse how do i update it each month with new security patches ? i have installed TWRP. my intiall thought were to copy new update file and flash it again via TWRP but i'm afraid it will wipe out my entire data. ( in lineage OS this is how you upgrade ) so i kind need a bit help here. if anyone of you with rooted note20U just write down how do you update it each month. i would be very grateful. thank you for reading.
That's kind of the whole point.. by rooting you unlinked your device from samsung. to link it back you'd have to unroot and go back to the official firmware, do any updates necessary, then root again.
