[Xperia Z4 Tablet General] Kenshiro7:
Thank you very much kuroneko007 for the info on accessing the service menu, I also have an only Wi-Fi Model.

The firmware you posted 28.0.A.8.260 is old now, the new firmware is 32.A.2.0.224, maybe you missed that?

you can use xpericheck.com to keep an eye on updates for all xperia devices

https://xpericheck.com/device/SGP712

Thanks again.
[Xperia Z4 Tablet General] kuroneko007:
No, the 260 firmware is needed to get temp root to back up your TA partition.
[Xperia Z4 Tablet General] Kenshiro7:
Well brother, sorry it's my mistake!

It looks you were offering the link for the 260 firmware version made for the Wi-Fi Z4 instead of the LTE version which is included in this guide so we can back up our TA partition before rooting it and updating it to a newer firmware.

Thanks again for explaining this info and helping us out here.

Take care.

[MENTION=5769394]najoor[/MENTION] I think the 1.2 step should become 1.1, imagine wiping your tablet only to realise the bootloader can not be unlocked :crying:
[Xperia Z4 Tablet General] anixan:
Bricked :(

I tried the FlashTool with the uploaded tft file SGP712 however now I get a black screen only when try to start please help!!!!

It vibrates when i press the power key and nothing!
[Xperia Z4 Tablet General] najoor:
Don't panic. It is difficult to permanently brick these devices by flashing an ftf. At times like this it will help of you provide the log from flashtool to see what went wrong.

I don't own a wifi model but I can try to help you. If you just want to return the tablet to a working order just search online for any ftf for your tablet and flash it again and check all the wipe options. If you want to complete the guide here find a 28.0.A.8.260 firmware for your tablet and flash and continue the guide.

Just make sure the firmware is for your tablet and not any other tablet or model.
[Xperia Z4 Tablet General] Hybel1507:
Did you do a full wipe before installing the firmware?
[Xperia Z4 Tablet General] anixan:
Thanks for the help it was a different firmware causing the problem :)

If i just want to root and install custom TWRP? How can I do?

Btw, does anybody here has a pre-rooted 32.2.A.253 for wifi version model SGP712?

Thank you
[Xperia Z4 Tablet General] najoor:
This guide is as simple as it gets. If you want to root you still need to unlock the bootloader and still have to flash a custom kernel. It is just how things are done after lollipop. The only steps you can skip are to backup your TA partition (if you never want to restore the tablet to its original factory settings) and to emulate the drm (if you don't care about sony's proprietary camera and image algorithms which will be permanently lost after unlocking the bootloader). And because of what I just said, there is no pre-rooted ROM. So have some patience and read through the instructions.
[Xperia Z4 Tablet General] vodanhdaisu:
Thank you for your reply. I've used Z1 before and have a little bit about Xperia flashing custom rom. And i just bought a Z4T wifi few days ago

My Z4T is currently running stock 28.0.A.8.260. What I'm thinking I'm gonna do is so:

1. Flash 32.2.A.0.253 stock firmware via Flash tool as normal Xperia devices or I need update device via OTA ?

2. Unlock bootloader

3. Install AndroPlus kernel to get rooted?

Am I thinking right way? Thank you for your advice
[Xperia Z4 Tablet General] najoor:
You are thinking correctly and what you said will work (with either flash tool or ota). I just want to remind you to think twice before forgoing the backup of your TA partition and what that means.

Good luck!
[Xperia Z4 Tablet General] vodanhdaisu:
Thank you once again

After checking service mode by entering *#*#7378423#*#*. This is what I see on the tablet:

Does it mean my tablet is unlocked bootloader already ?
[Xperia Z4 Tablet General] najoor:
No, it only means it can be unlocked.
[Xperia Z4 Tablet General] vodanhdaisu:
Hi There

I;ve already unlocked bootloader for the tablet, then I boot to fastboot to install boot.img which is extracted from Andro Kernel v36

As the installation guide of AndroKernel, Reboot the device by pressing volume button, then TWRP will show up

But I can not enter recovery to see TWRP

Please anybody help me

Thank yoo
[Xperia Z4 Tablet General] Hybel1507:
Did you actually flash TWRP? Step 4 of thr guide? It worked very well on my SGP771.

Gesendet von meinem SGP771 mit Tapatalk
[Xperia Z4 Tablet General] Jadog:
Thanks for taking the time to make this guide. Before beginning this on my SGP712, there is one thing that is unclear to me. Your instructions in step 2.1 show that you flashed the AndroPlusKernel onto the device. If I follow the link you provided to download this Kernel (https://kernel.andro.plus/kitakami.html), the AndroPlus notes that his custom kernel includes TWRP and disabled Sony RIC. Following down further in your direction in step 2.4, you recommend configuring to "Disable Sony RIC" and set "Install TWRP Recovery" to No.

If these steps have already been integrated in his kernel, why do we need to do it again? Just want to make sure I have everything covered before I start.
[Xperia Z4 Tablet General] yu4565:
stuck, touch unresponsive

I'm stuck with an unresponsive screen after completing step 2.5

I used Z4T_SGP712_AndroPlusKernel_v36

Is there anyway I could reboot the tablet in fastboot and reflash with another kernel providing that I have an unresponsive screen ?

Thanks

Edit : managed to reboot, looking for a working kernel
[Xperia Z4 Tablet General] najoor:
Take Sony's stock kernel and patch it as prescribed. You well not have twrp though.
[Xperia Z4 Tablet General] Srikar_NBK:
Hi. I recently got the Xperia Z4 tab Wifi version (SGP712) and currently have 32.2.A.0.253 as the build number. I have read the instructions in this thread and need a few clarifications before I attempt to root my tablet.

1) The instructions suggest that I need to flash back to firmware 28.x.x.x to unlock the boot loader and acquire root. Is there a Stock rooted ROM with the latest firmware( 32.2.A.0.253) that I could flash post rooting? I want to root, but don't want to be stuck on old Stock ROMs. If yes, where can I find the rooted version of the latest Stock ROM ?

2) I have seen a few AOSP ROMs in the dev thread, which I know once flashed, will be losing proprietary Sony features. How stable are these AOSP ROM's on this tablet ? How does the camera perform on AOSP ?

Thanks for all the help
[Xperia Z4 Tablet General] najoor:
You don't have to go back to lollipop for unlocking the bootloader. You do that to make a backup of the TA partition so you can restore the tablet to its factory issued condition of you change your mind about unlocking the bootloader. More explanation is in the op.

I don't know about AOSP but you seem to be confused about what causes the Sony features to disappear. it is the unlocking the bootloader life the Sony keys not the flashing of a custom rom.
[Xperia Z4 Tablet General] Srikar_NBK:
Thanks for the response. Is there a rooted version of the latest Stock ROM that I could flash post rooting?
[Xperia Z4 Tablet General] najoor:
I don't know of any. You will have to flash a patched kernel and root it the way is outlined in the op.
[Xperia Z4 Tablet General] Grutinet:
Hi everyone,

I have a Xperia Z4 Tablet Wifi (SGP712) and I followed the tuto to root it. Everything went fine but when I flashed a custom Kernel (2.4 - 2.5 section of the tutorial), my screen stopped responding. It is as if the Kernel was broken or something, so is the link between the hardware and the software.

To sum up,

- I created and backup my TA partition --> OK

- I unlocked the bootloader --> OK

- I flashed the last tft file : 32.2.A.0.253 / R4C --> OK

- On this site (https://kernel.andro.plus/kitakami.html) I downloaded the last version of the kernel (v31) : Z4T_SGP712_AndroPlusKernel_v31.zip, which is the one matching my tft version

- I downloaded the rootkernel from this site (http://xdaforums.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605) and copied the boot.img file as it was specified in the tuto. I also placed in the folder a SuperSU zip to root the tablet.

- I entered the command :

rootkernel.cmd boot.img boot-patched.img

and answered the questions like this :

- Sony RIC is enabled. Disable? [Y/n] Y

- Install TWRP recovery? [Y/n] TWRP automatically didn't install because of the kernel but I don't remember the error message

- Found SuperSU-v2.71-20160331103524.zip. Install? [Y/n] Y

- Install DRM fix? [Y/n] Y​

It created the boot-patched.img file.

- I then rebooted in fastboot mode and entered the command

fastboot flash boot boot-patched.img

Now my screen does not respond anymore. I can't stop or reboot it using the physical buttons because it needs an input on the screen. All I can do is lanching the camera by double tapping the power button (yay !).

I can't do anything with Xperia Compagnion because it needs to use the MTP mode on the tablet, neither Flashtool because I can't turn it off.

The only idea that comes to my mind is to let the tablet run out of energy (this can be long...). Then use Flashtool to flash the last 32.2.A.0.253 / R4C once again with wipe mode. Do you think that this will put the stock Kernel back ? Do I have to flash it separately ? What would you do in my case ?

Thank you very much, great tuto by the way ;)
[Xperia Z4 Tablet General] kuroneko007:
Use a different version of the kernel, it's up to v40 already so you seem to have missed the page for the newer versions.
[Xperia Z4 Tablet General] halfvast:
Hello,

I had exactly same problem. You need to use rootkernel 4.51 with a fix instead of rootkernel 5 which causes a screenrespond problem. The fix below is needed if using a firmware .253 or newer. This method works with a newest firmware .305 and Androplus v40 kernel. Hope this helps :)

To fix rootkernel 4.51:

1) Go to rootkernel/Android/twrp_common_kmodules

2) Make a copy of the 3.10.84-perf-g4a67e86 folder

3) Rename the new folder you just copied to 3.10.84-perf-gf1cfa5f

4) Use RootKernel as usual
[Xperia Z4 Tablet General] Grutinet:
Oh great ! Thank you for the precision. I will try this once my tablet is out of energy (so I can boot it in fastboot mode) and I keep you in touch.
[Xperia Z4 Tablet General] killdozer56:
Hi,

You can force the tablet to shut down by pressing the power button and volume up button until the tablet vibrate twice and shut down

Hello guys im new in rooting world and dont know too muchab that , but i need ur help if someone is generous by rooting my device with team viewer!:)
[Xperia Z4 Tablet General] _Nostromo_:
Hi guys,

I am preparing the "boot-patched.img" from a CE1 Customized 32.3.A.0.376 through the rootkernel_v4.51 ("fixed") procedure and I get a message "Skipping SuperSU integration. Only supported for Android 6". Am I doing something wrong or is it not possible to prepare this patched img for Nougat with this version of rootkernel? Or will it be possible to install SuperSU via TWRP later on during the process?

Also (maybe as a result of using Nougat kernel?) the rootkernel.cmd does not create the "boot-patched.img", it only gets to a step "Configuring secd" and hangs there forever. Within the directory the following items are created: a folder called "ramdisk", file called "kernel" (no extension) and an archive called "rd.gz".

- Unpacking kernel

Found elf boot image

Kernel version: 3.10.84-perf-gda8446f

Found appended DTB

- Detected vendor: somc (Sony), device: karin, variant: row

- Unpacking initramfs

- Detected platform: 64-bit

- Detected Android version: 7.0

- Disabling dm-verity

- Sony RIC is enabled. Disable? [Y/n] Y

Disabling Sony RIC

- Skipping TWRP recovery. No kernel modules for 3.10.84-perf-gda8446f available

Skipping SuperSU integration. Only supported for Android 6

- Install DRM fix? [Y/n] Y

Configuring tpm-service

Configuring credmgrd

Configuring secd

Tried this several times on two different computers but without success. Would you have any suggestion how to make this work with the 32.3.A.0.376 version?

Thanks a lot for any hint.
[Xperia Z4 Tablet General] DHGE:
To start: I have never used Tobias' tool.

It is rather old and IIRC unmantained.

You could try my guide - this works on my devices.

Short:

Install ROM (version) you like.

Get a custom kernel for this ROM with RIC and DM-verity disabled.

Flash kernel via fastboot or TWRP.

Flash SuperSU via TWRP.

Another approach in the making patching stock kernels:

https://xdaforums.com/crossdevice-dev/sony/poc-real-trim-instead-drm-fix-t3552893/post71469725

In the credits you have Tobias again.

I have not tried it so far but it seems to work (you should know what you do: PoC) on our 2015+ devices and Nougat.
[Xperia Z4 Tablet General] _Nostromo_:
Thanks a lot, tried your way but unfortunately ended up in a bootloop. Pushed back the 28.0.A.8.260 version, recovered the TA, pushed the 32.3.A.0.376 and all works. Obviously no root. I give up, apparently am not in the shape to manage, however on my previous Sony devices (Z1C and Z3C) I was always able to get it rooted. Maybe I am just to tired for it now, might retry some day, for now I have to get used to living as a regular BFU... :D

Thanks for trying anyway! :good:
[Xperia Z4 Tablet General] DHGE:
you really NEED a custom kernel

try Androplus's kernel
[Xperia Z4 Tablet General] _Nostromo_:
Ok, when you say so, I'll have to try... ;)

EDIT:

As inside I felt I'd stick with the stock kernel I eventually followed this guide https://xdaforums.com/z4-tablet/general/guide-nougat-drm-fix-root-twrp-sgp771-t3555265 and it worked perfect. Now I have a rooted Nougat with my original DRM keys restored (from the original backup) and the whole world is just beautiful...

Applied the guide succesfully after a clean flash to the "SGP771_28.0.A.8.260_1296-0518_R6A".
[Xperia Z4 Tablet General] Mister Papillon:
Hallo Xperia Expert´s, ... i have there a Question to you.

I will "ROOT" without unlock the Bootloader to make a TA-Backup for my DRM-Keys.

I have a Sony Xperia Z4 Tablet LTE ( SGP771 ) with the newest OTA-Backup. This is Android 7 - 32 . 3 . A . 0 . 376.

Before i can "Unlock" the Bootloader on my Tablet, i have read that i must make a TA-Backup that i don´t not loose my DRM-Keys.

That i can do this, TA-Backup must have ROOT on my Tablet.

For a ROOT with "ioyroot" i must make a Downgrade to - 28.0.A.8.260 firmware.

How i can do this with a "LOCKED BOOTLOADER" ?

SOLVED !!! I have a couple of installed the Flashtool new, downloaded the Flashtool from other Source and new install. After the first Start the same´st Problem.

After the Second Start from Flashtool i become install a "NEW Driver" ( SomC). And now run Flashtool perfect. I can do my Firmwareflash without Problem´s.

[Xperia Z4 Tablet General] Grutinet:
Hi, I flashed the 32.4.A.1.54 stock ROM with flashtool to my SGP712 tablet. Then, in order to have DRM fix + root, I followed the chapter 2 of the first post of this thread.

I created a new boot img that I flashed using the command "fastboot flash boot boot-patched.img". This image contains the v43 of AndroPlus kernel and the last version of SuperSU.

I should have read more carefuly the topic, since it has hard bricked my device. It doesn't boot anymore, neither charge when I plug it in.

I tried to flash another time the stock ROM in order to fix it but since it is bricked, I can't boot it in flashmode when Flashtool asks me. I am a little bit stucked.

Do you know the usual way to recover from such a hard brick ? Thank you very much.

One of my biggest pet peeves and first world problems, is the battery icon or % or anything battery related whatsoever showing itself on my phone. I do not want to see the battery life displayed anywhere ever on my phone, it's too stressful and pisses me off seeing it. I know when my battery low, and will check it in the Settings menu myself like once a day, or see it when charging.

How do I get rid of the battery icon and % from showing in the lockscreen status bar ? I use the Xposed Wanam app to hide the battery icon on the home screen status bar. But for some reason I still see it on the lockscreen.

I have the T-Mobile Note 5, running an International Marshmallow ROM. I am using the latest official T-Mobile firmware, bootlloader, and modem. But previous Lollipop ROM's I was always able to hide any battery stuff on the lockscreen.
