So I need the following information from you:

Device: XZ2 or XZ2C or XZ2P

The Terminal Output of

cat /sys/devices/dsi_panel_driver/panel_id

IN TWRP IMG FILE AND IN TWRP INSTALLER ZIP AND the android system

(You can use

adb shell

or your terminal. In both cases you need to get root with the command

su

first. And you need Magisk Root)

Touchpadhardware:

"Dial"

Well, I had already tried it with my pw, but it didn't work. But now I gave it a new try, and voilla - it works. I'm sure, it's because of my thick fingers, and simply the pw was wrong :laugh:

Thanks :good:
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Nice to hear! :D
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
Device: "XZ2C"

Output TWRP img file: "4"

Output TWRP Installer Zip: Touch doesn't work

Output Android System: I cant' boot

Hardware: I remember CLEARPAD this morning

UPDATE: I've flashed magisk and permissive all from twrp image and now it boots fine but touch doesn't work, I think there is a problem with kernel
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Yes, number 4 and CLEARPAD is correct.

Did you use the latest twrp-3.2.3-0-xz2-xz2c.img file?

You can easily boot your system by unziping the stock kernel installer zip and flashing the kernel.img with fastboot flash boot kernel.img
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
Yes, I think there is a problem with kernel, touch doesn't work on android system or twrp installer, it works only in twrp img. please send me kernel of xz2c not xz2
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Weird, you are the first XZ2C owner with this problem.

The XZ2 and XZ2C having exactly the same SHA512 hash.

But even, if these are completely exact hyper same kernel, I will repack one with the "XZ2C" Kernel.

Please look into the google drive, there is a XZ2C_Beta folder.

Please flash this img file and test TWRP touch.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
[MENTION=5527402]Michele2[/MENTION] could you tell me the exactly Model Name?

H8324, H8314, SO-05K ?

And your firmware version has the required version from the front project page?

And you are booting the correct treble slot with this version number?

And you deactivated with vbmeta.img and its parameters the AVB stuff?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
H8314, I'm trying please don't go to bed lol
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Good morning, since 13 minutes :P

Please follow the exact steps on the third page and redownload the needed files :)

Other people doesn't get this problem on their XZ2C :(

Maybe you got a Hardware Revision 1 device?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
H8314 my firmware is 51.1.A.11.51, I haven't any idea... Could u send me kernel.img of XZ2C also if checksum match with XZ2. please
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Look into the XZ2C_beta folder :)

And good night. :D
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
Well I'm sorry to be noob but I don't understand the install process.

Here is what I intend to do :

1. On my XZ2C : Activate USB debugging

2. Check the option 'Unlock bootloader' in the parameters

3. Encrypt my sd card (or not?)

4. Connect the phone to the computer

5. Open adb and type 'adb devices'

6. Type command 'adb reboot recovery'

Until then, no mistake?

7. I don't know then........ Do I have to copy all the folders (stockkernel-xz2-xz2c-installer ; twrp-3.2.3.0-xz2-xz2c-xz2p-installer ; Magisk-v17.1 ; permissive) into the adb folders?

8. Newflasher or fastboot? Don't understand which one to use or if I have to use adb.

9. With adb/fastboot /Newflasher (in recovery mod?) which commands have I to enter? and in which order?

Thanks for semi noobs like me
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Third post in thread :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
I don't understand it completely. Even if we have to unlock bootloader before doing anything. Too bad. But never mind, I'll use my phone without root. Thanks whatever!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
After I slept I will help you.

Or do you only need the android Plattform Tools with adb and Fastboot?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
No, this I already have on my computer (I already flash my former x compact). But I even don't know if I have to unlock bootloader before doing anything
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Android USB debugging is needed for ADB :)

The zip files need to be on sdcard for twrp.

The img files need to be in pc for Fastboot.

And use the Sony documentations :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
1. And newflasher is to use before doing anything or adb is good enough?

For doing this :

fastboot flash boot twrp.img

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img <- IMPORTANT OR THE SYSTEM WON'T BOOT!

Reboot into RECOVERY (Power + VOL DOWN)

Then you do this (with file installed on your sd card before)...

2. Reboot into RECOVERY (Power + VOL DOWN)

TWRP flash stockkernel-installer.zip <- IMPORTANT OR THE SYSTEM WON'T BOOT!

TWRP flash twrp-3.2.3-0-xz2-xz2c-xz2p-installer.zip

Reboot into RECOVERY

TWRP flash Magisk-v17.1.zip <- IMPORTANT OR THE SYSTEM WON'T BOOT!

Twrp drmfix (Optional)

Reboot into SYSTEM

Magisk App -> "Module" flash permissive.zip (Optional)

Reboot into SYSTEM (Optional)

... Directly on your phone from twrp? Or from adb with Twrp booted?

3. Or can I do anything up but only that from adb :

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img <- IMPORTANT OR THE SYSTEM WON'T BOOT!

fastboot set_active other

Reboot into RECOVERY (Power + VOL DOWN)

TWRP flash twrp-3.2.3-0-xz2-xz2c-xz2p-installer.zip

fastboot set_active other or switch the slot via TWRP

Reboot into RECOVERY

TWRP flash Magisk-v17.1.zip <- IMPORTANT OR THE SYSTEM WON'T BOOT!

Twrp drmfix (Optional)

Reboot into SYSTEM

Magisk App -> "Module" flash permissive.zip (Optional)

Reboot into SYSTEM (Optional)

?

PS : do I have to install Newflasher from and on the phone or on the computer? (if it's on the computer, do I have to enter commands from newflasher software?)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] nasko_spasko:
Wow! Congrats on the working TWRP! You've finally pulled this off. :) :beer:
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
[MENTION=6031898]MartinX3[/MENTION] FIXED! PLEASE NOTE: checksum of kernel's XZ2c(kernel_X-FLASH-ALL-B6B5.img) 00D94518 is different from kernel inside stockkernel-xz2-xz2c-installer.zip 53AD34E. With the kernel_X-FLASH-ALL-B6B5.img I haven't any problem concerning touch and everything is fine! from H8314. Please you need much more testers for XZ2c, maybe the two kernels I dont believe they are the same as you think. the weight is the same, but checksums are different. Maybe I'll decompile it and I'll analyze the differences. Please keep me update, I'm interested in.

2) where is button of MTP in TWRP? it's hidden somewhere

[MENTION=8363210]sToRm//[/MENTION] your "fixpack.zip" routine corrupts(overwrite something) TWRP boot image patch, so this is a workaround but it seems to work for my XZ2c --> in order to avoid to stuck on TWRP splash screen we need to "re-execute" TWRP boot image patch IMMEDIATELY AFTER flash of fixpack.zip --> there is a wrong overwriting in your code, I think, I prefer you'll solve conflict.

Hello friend [MENTION=1417783]pandemia[/MENTION], where can I get the chiness drm fix?!!?? Thanks in advance!!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pandemic:
On a chinese site, not here but cant find it back.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] laoli0913:
Gfan? Or where?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pierfranc:
So before installing recovery Dmrfix is needed? And what problem I will find installing it? Camera works? What kind of bug? I would do this to get root
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pandemic:
Yes i guess but cant remember so sorry.

No not needed and yes all works
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pierfranc:
Oh, that's amazing... And could I roll back to the factory state? Because I should send it for warranty since I am having touch and heat issue. And how to do it?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
[MENTION=3142060]old.splatterhand[/MENTION]

With your XZ2C, can you confirm the not working touch with the TWRP universal installer?

MTP will follow later, at the moment, you can put it on SDcard or use ADB push/pull/sideload. :)

Hmm, what fixpack.zip do you mean?

The only problem get stuck at splash screen is, if I used newflasher or something similiar before.

Because I need to execute fastboot vbmeta with its parameters again. (verification against manipulations getting reactivated)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Do you use hardware revision 1 ?

There should me a text on the XZ2 delivery box.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pierfranc:
Yes it's hardware revision 1 XZ2 Compact
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
fastboot need to beexecuted in fastboot mode with the fastboot appliation and an usb connection to your computer.

adb needs to be executed in twrp (with usb debugging enabled) or in your system, but both times with an usb connection to your computer.

the zip files need to be executed in TWRP in exact the right order.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
I had problems in the past with encryption so I wonder if there is a way to disable it completely also with xz2(c) and keep it disabled after formatting /data?

maybe a custom twrp version or a flashable zip like for some other phones?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
No more formatting needed :P

You will need your PIN or Password in TWRP to encrypt your userdata.

I did update the instructions on third post in the past :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
Hi back.

My phone is now unusable. Touch doesn't work... I followed all the step reffered on post #3.

I have an X2C (H8314).

Here's what I did :

- I used newflash to install a clean 51.1.A.11.51 firmware : it worked perfectly !

- Then I unlocked the bootloader with the Sony process and then the adb command. It worked :)

- Then with the last Adb I entered :

* fastboot flash boot twrp.img

* fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

And when I Rebooted into RECOVERY (Power + VOL DOWN), It worked.

I than transfered the kernel, Magisk and twrp installers and permissive files with adb push. It worked.

then directly with TWRP I installed first stockkernel (the xz2-xz2c one),

then the twrp-3.2.3-0-xz2-xz2c-xz2p-installer.zip

But when I rebooted in recovery, the screen wasn't touch sensitive anymore. So I wasn't able to do anything.

I retried the whole process installing the kernel the TWRP installer and directly after tthe MagisK but same problem : when I rebooted the System it works, but with touchscreen non sensitive to my fingers anymore !

What can I do? Help !
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Could you try the files in the XZ2c_beta folder instead? :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
thanks I saw this progress but wanted to remove encryption anyway. btw ok, as first thing will try without formatting (if I decide to unlock BL.. I am still thinking :p )

one thing: if I have sequence (no pin or password) I will be asked for my sequence in twrp, or I have to convert it to a digit pin code like I had to do lot of time ago in my old mi5?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
[MENTION=8568927]Yoannjap[/MENTION] [MENTION=5527402]Michele2[/MENTION]

I uploaded a new stock kernel installer in the XZ2c_beta folder, too :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Has anyone made experience with this?

I use a 4 digit pin, which works. :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] old.splatterhand:
Same question here, i don't use Pin/Password...?

I'm sorry, i'm not able to unlock and flash the whole process before tomorrow evening. I need the phone working til then.

But also i have model H8324. So my experience may differ from the other models with touch problems.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
But at least you could use a pin the same as your simcard pin.

So you wouldn't need a real different pin to remember :)

But you hadn't any touch problems with the twrp universal installer? :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pandemic:
Yes you can but not with locked bootloader because we have nothing to back up our drm keys.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
no simcard pin here either, only lockscreen sequence :p
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
It is funny that even without a DRM fix my camera preview and my camera are fully working.

(Not the other DRM stuff like backup & restore or video optimizing)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] old.splatterhand:
I have not started yet. Still locked.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
I am interested in further tests.:)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
I played with the open camera app settings.

I deactivated the camera API 2 and can achieve the entire 19MP the stock camera can achieve.

Also the HDR is amazing.

I can't see quality differences.

Maybe it suffers only in AOSP.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
I confirm but problem wasn't twrp universal installer but the wrong stockkernel.zip for xz2c.

Fixpack.zip is the new drmfix of Xperifix and as storm said, problem isn't drmfix but twrp, the new drmfix overwrite some files of twrp and it stucks... I solved flashing manually his drmfix and ONLY AFTER this I've flashed Twrp universal installer to avoid twrp splashscreen freeze.

Any solution for warning at boot: "Your Device Software Can't be Checked for Corruption

Please Lock your Bootloader"?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Could you test the files in the XZ2C_Beta folder? :)

How did you get the fixpack.zip?

I am in contact with STORM and use the XperiFix application, which sends his drm.zip through the TWRP ADB remote shell.

And I don't get any touch problems and don't get stuck at boot/twrp screen.

I don't have one, but it doesn't disturbs me.

I think it is impossible to remove this, until sony would make the bootloader open source, which will never happen.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pandemic:
No thats normal
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] old.splatterhand:
For sure i let you know, how it goes!

[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Michele2:
We dont need separate twrp installer, only separate kernel
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Because of XZ2c

The Xz2 was fine :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:

I don't know if I see that correctly, but [MENTION=6844550]M-Rom[/MENTION] pirated the drmfix from [MENTION=8363210]sToRm//[/MENTION]

And he is not providing the source for its TWRP.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:
Thanks a lot to MartinX3. It worked with the XZ2C !

Just a last question: someone has tried to install Xposed beta 3 through TWRP-zip-falshing or directly with Magisk? DOes it work for you?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
I am happy to help you :)

I don't use xposed anymore since I switched from the Nexus 6 to the XZ2 :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:

Thanks!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Yoannjap:

[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
AFAIK you can NOT relock bootloader in xz2.. and even if you could your drm keys are lost, so I doubt they will repair your phone in warranty (in italy for sure they don't if you unlock the BL)

I miss backup TA....
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Thanks for all the thanks and of course I will update TWRP in the evening for PIE :laugh:

But I am not sure how long it will take!

I would wait with the pie update!

OpenCamera is working with full resolution :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Btw.

Now the XZ3 is sharing the SAME firmware as the XZ2 and XZ2C.

So I think TWRP for the XZ3 is easily to adapt.

I hope the next XZ2 Premium update will share the same version number.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Btw. Did the OTA new flasher update instruction work?

Fastboot Vbmeta again.

Fastboot Switch slot.

Boot into twrp.

Twrp Twrp installer.

Fastboot Switch slot.

Reboot into twrp with pie.

Twrp Install magisk.

Reboot into system

?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
The camera survives the android pie upgrade.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Pandemic:
Anyone ?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Btw.

It could be that you need to switch the slots before installing pie.

If you didn't install the September update on both slots with new flasher.

But at least, you can install Oreo with twrp on the other slot again. Boot twrp. Execute twrp installer and switch to your pie slot.

Thanks to treble and the redundant partitions, you can install 2 firmwares at the same.time.

But don't "downgrade" your userdata.

Never boot into previous system without a good backup!
