How does the DRM fix works wth this kernel? Did you do a dirty flash or full wipe? I am still with previous rom version :)
[Xperia Z4 Tablet Android Development] GhostLeader:
Im still on Android 6 with Andro Kernel and DRM fix... works very fine but battery ist not the best. Not bad, but could be better.

Is this Rom good? DRM fix working?

Or is it better to use linage rom?!?

My 771 gets stuck at the sony logo when I flash this.

Only boot image I can find that works on mine is AndroPlusKernel_v43
[Xperia Z4 Tablet Android Development] Youply:
Hi,

followed the instructions but no root:

Comming from the precious DRMfix with root on 7.0.

Did a flash of customized DE .160 with flashtool.

Flashed boot image 712, TWRP -> everything is booting and TWRP working.

When finally flashing supersu from TRWP - > script runs until

"-patching init*.rc,fstabs, dem-verity"

"- calling user ramdisk patch script"

"--failure, aborting"

After that - system normally boots with .160 but obviously no root access.

Any suggestions?

Thanks a lot

Just to express my thanks and gratitude to [MENTION=5111503]Nimadroid[/MENTION] for his work. I was completely stuck until I found this Guide.

Any ideas what i need to do to get this to work on my 771?

I've only been able to get AndroPlusKernel_v43 to work on my device.

What am i missing?
[Xperia Z4 Tablet Android Development] rebski:
All I can do is to outline my steps in sequence in case any of it helps.

1. Flash Sony Firmware 32.4.A.0.160_R2E Customised UK

2. Flash the [MENTION=5111503]Nimadroid[/MENTION] Kernel

3. Flash TWRP Recovery

4. Use TWRP to flash LineageOS

4. Use TWRP to flash SuperSU

5. Use TWRP to flash GApps

Being new to this it was a long slog for me to gather the information needed to Unlock Bootloader and all that followed.

Others may have the advantage of being already familiar with Fastboot, Flashtool and the rest.

But I want use "X-Reality for mobile" display mode. I followed this instruction

I backuped TA.img and use "rootkernel_v5.23"

to make kernel with TA dm-verity SONY RIC off. But After I flash the kernel made by myself, the touchscreen doesn't work.

Don't know how to fix it.

[Xperia Z4 Tablet Android Development] Irieone:
Hello, I recently gota new Z4 tablet (SGP712) that is running stock 32.4.A.0.160. The bootloader is still locked. I need to unlock before flashing this kernel correct? Once the kernel is flashed, I install TWRP, and SuperSU or Magisk?

In the end I just want a stock, rooted tablet w/ TWRP. Do I understand this correctly?
[Xperia Z4 Tablet Android Development] DHGE:
Yes - and you need a custom kernel with RIC and DM-Verity switched off

I strongly recommend backing up your TA before unlocking the bootloader.

You do not need to flash TWRP (although convenient). You can fastboot boot into it.
[Xperia Z4 Tablet Android Development] meuchael:
Does it work with 32.4.A.1.54?
[Xperia Z4 Tablet Android Development] DHGE:
It might.

[Xperia Z4 Tablet Android Development] DHGE:
Yeah - this is similar and munjemi borrowed from Tobias IIRR but with the additional twist of massaging your TA-keys in which makes the phone look as if you have never unlocked the BL.

Because of good experiences with ta_poc I use this e.g. also for my XZ where I have my keys backed up.

Sorry, my fault, .160 kernel is actually working with the latest FW ... It was Magisk that caused the bootloop on my tab not your kernel hehe

Only one question, did you leave kernel completely stock?

Just asking because kernel apps shows that cores 6/7/8 are inactive and i cannot activate the last 3 with no app and no setting ... Only cores 1-5 are working wich is funny that only one core of the big cluster is online ....

Hi, I just flash the kernel and twrp into my SGP712.

But I can't boot in recovery mode.

I just wondering if I flash the kernel successfully.

Is there any way to check that ?
[Xperia Z4 Tablet Android Development] Random667:
nevermind
[Xperia Z4 Tablet Android Development] DHGE:
What is "this"?

If you have no backup of TA then you will never be able to return the tablet to the (software-) state you got it with.

In some countries that can cost you the warranty in case of (unrelated to software modifications) hardware defects.

On newer devices you get an ugly warning each time you reboot the device. That affects the resale value.
[Xperia Z4 Tablet Android Development] ultenhiemer:
There aren't any prerequisites with this... Normally with all the other android developments they ask to "Enter service Mode by dialing *#*#7378423#*#* -> Service info -> configuration, and make sure the device is unlockable." before you can even begin... Obviously I can't as the bootloader on my device is mobile network locked by O2 UK. I've not been able to root so far as nothing is available for my device like that.

Any chance that this might be a first? I wouldn't want to put my hopes up for rooting my device if this can't root either with the bootloader locked by O2 UK.
[Xperia Z4 Tablet Android Development] ultenhiemer:
Anyone going to give me a simple answer for my message above?
[Xperia Z4 Tablet Android Development] _TTTT_:
Is there no simple way to root SGP771 with KingRoot or Magisk without all files getting deleted without 10+ steps. And just root it with a few clicks like most youtube videos suggest for other phones?

/Thank You!
[Xperia Z4 Tablet Android Development] DHGE:
To answer them very unspecificly: no you can not

With locked bootloader every modification you mention will send your tablet into a bootloop or brick it.

No root, no busybox, no third party kernel ...

The best option you have is to get the latest stock ROM as an over the air update.

If that does not work you DL the latest ROM via Xperifirm and flash it with newflasher.

SONY abandoned our devices in October 2019.

I am eyeing a SAMSUNG Tab5e since there is already some thirdparty ROM development and the battery on my LineageOS driven SONY last only half a day now.

It is not a big upgrade considering 4 years (2015-2019) hardware evolution but SGP771 was top spec hardware at the time and the Tab5e is medium spec of 2019.
[Xperia Z4 Tablet Android Development] retikulatus:
Dear DHGE,

thank you for your reply.

I will, then, stop wasting time and energy trying to do the impossible.

I will never buy a smartphone/tablet sony again, as i don't like this lotery stuff about unlocking bootloader allowed "yes/no" and the drm+ta thing too...

Yes, samsung devices seems to be more "custom roms friendly" ;p

i have the 4/3 galaxy tab s3 and it works like a charm on an inofficial RR rom :)

warm regards
[Xperia Z4 Tablet Android Development] alex009988:
Well. I didn't have stock Rom for years and tried the last one 32.4.A.1.54 now. I used z5 root kernel script. So my results:

Drm fix leads to frozen touchscreen.

Magisk 21 installs and boots but Magisk app just hangs.

I got root with supersu 2.82 and it seems to work but it broke something on system. Es file Explorer and chrome hangs, no apps can be installed, installation process just hangs and the same thing with removing. I think if we want to have root on stock we need new compiled kernel like a andro+ kernel was.
[Xperia Z4 Tablet Android Development] jelbo:
I have the most success with stock 32.2.A.0.305 (Android 6.0.1). AndroPlus kernel v40. Latest Magisk works fine, no battery draining issues. Stock Android 7 had bluetooth and/or battery issues.

Relock, back to stock for warranty. Touchscreen malfunctioning

Hi, I unlocked my bootloader and have TWRP installed. I really need a dumbed down explanation on how to restore everything to get a warranty repair. I cannot use the touchscreen, I was talking on my phone and wiped sweat off the screen and for days now I cannot use the phone. I can't even use TWRP. I think the digitizer is broken.

To clarify some potential misunderstanding:

I cannot even create a VPN configuration. Whenever I tap on the plus-Button in the VPN-activity the encryption password for my device is asked. And that again and again ...

In the meantime I found a App from my router's manufacturer (Fritz!Box), which easily lets me create the VPN and gives me a stable connection.

I also had a contact to a very nice person from OnePlus, but I should re-lock my bootloader, which I want to avoid, because a rooted device is ways more important for ma, than creating a VPN with Android's on-board-tools.

Hope this clears, that the problem is not connecting to a VPN, but creating a connection.

Cheers, Klaus

[OnePlus 5 Questions & Answers] Pouic:
Exactly what i'm saying, if I understand your steps correctly : when you click "+" you are prompted with the edit credentials of the vpn

You have to input the user password and shared key password in the correct places.

If you mix them up the next prompt will ask you again, and again, and again, and again for the password
[OnePlus 5 Questions & Answers] kr_ke:
Exactly this IS te problem: When I click the '+'-Button I am asked for the password of my device.

I am *NOT* prompted for the credentials of a new VPN.

And then the password prompt repeats ever and ever ...

BTW, entering a wrong password here, is rejected, so I am sure to have entered the correct device-password.
[OnePlus 5 Questions & Answers] Pouic:
ok my bad

is it the password for credential storage ?

if yes : go to lockscreen options, disable swipe to unlock or password to unlock

instead set a pin to unlock or a schema

confirm the pin (or the schema)

go back to the vpn menu, and normally now when you click the "+" it will not ask you anymore for this device/storage password and let you edit/add a new VPN
[OnePlus 5 Questions & Answers] kr_ke:
The solution

Yes it was that password. Together with OnePlus-Support I found a Solution:

Switching the unlock method from password to pin or pattern, and then back to password, and then - voila -

Adding a VPN works!

Hello,

I am suffering from a really annoying problem for the last month and I cannot find a solution. I have tried to flash several firmwares but the EPD navigation bar seems to become somehow irresponsibe making the phone quite unusable.

With LP EU (5.0.0-EU1.1.87a and 5.0.0-EU1.1.124b) the navigation bar on the EPD seems to be working on the YotaHub without problems, I can navigate and I can unlock the screen by either double tapping or sliding. However, when I enable the YotaMirror the screen is mirrored but the Navigation bar becomes somehow disabled so I cannot exit the application that is running. The only way is turning on the normal screen so the EPD goes back to the YotaHub (quite annoying).

With LP RU (5.0.0-RU1.1.124 and 134 sideload) the YotaHub works fine but when I enable the YotaMirror a message saying "YotaMirror mode is enabled" with a help message explaining how it works and two buttons "Skip" and "Continue" which do not respond to any action; making it impossible to leave that screen. The only way to get rid of this is going to the normal screen and opening the YotaHub settings. This error seems to be already reported by another user: https://xdaforums.com/yotaphone-one/help/yoyaphone-201-stuck-androis-5-0-ru-1-124-t3571739

In MM (EU and RU) the area of the Navigation bar, no matter if YotaHub or YottaMirror seems irresponsible to any actions; so I cannot move across the panels in YotaHub nor exit an application opened in YotaMirror.

I thought this could be a hardware issue but I have discarded the option knowing that in LP it works and in both LP and MM the double tap unlocking feature (once enabled) unlocks the screen even being tap on that area.

I will continue flashing firmwares and eventually come back to the version of LP that was working fine (I cannot recall which one was it so I am downloading and trying most of them). But any help would be appreciated.

Thanks! :)

Hi [MENTION=1588304]tomgaga[/MENTION] Thanks for your response.

I can unlock the screen with in every mode: double tap, swipe and power.

I can fully confirm that this is not a hardware issue, meaning that the screen gets the touches as I have just captured the events with adb and saw how the screen gets the input event on the area of the screen "YotaMirror is enabled" that allows me to "Continue" or "Skip". So the taps are registered but it seems that this notification doesn't seems to work.

Anyone knows how to avoid this notification? I think this could solve the issue... :)

When you had this issue did it go away by just removing the mod? Or you increased the size? However, I believe that after a full reset this should be gone...

Danke!
