[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Rogier Oudshoorn:
That worked as far as the installation procedure!

However, after installation the phone keeps on restarting during the "starting phone ..." phase right after upgrade. I had a vanilla LOS 18 with MindTheGaps (that i flashed as part of the upgrade procedure).

I guess a factory reset is necessary?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Yes but there were infos on gapps requiring a clean flash here: https://wiki.lineageos.org/devices/akari/upgrade

>> start using them: You can only do so by performing a factory reset, which will also remove all your data. Download the appropriate version now (use the arm64 architecture)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] shoey63:
Maybe your Windows isn't set to show system extensions. In that case flash the lineage recovery without the ".img" at the end
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Rogier Oudshoorn:
Yeah, i had them on the phone in LOS 18 too. After factory reset, the phone doesn't enter the start using wizard - just seems to wait forever, and then it restarts in ~5 minutes.

Guess i'll have to go back to 18
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Maybe you had some other gapps addon than MindTheGaps before (like opengapps or nikgapps). Switching packages is only possible with a clean flash. You could try to switch slots manually so you're back on 18.1 in order to backup your data and start clean flashing 19.1.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Rogier Oudshoorn:
Looks like the device isn't booting at all anymore, beyond xperia flash tool repair. New plan: get another phone.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
If you can get into fastboot mode you should be able to fix that

How do i get Magisk installed properly? I have the Magisk app on my phone but it wont update and root checker says root is not properly installed. What have i missed?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] casouzaj:
Copy the ROM's boot.img file to your phone. On the Magisk main page, click to install (the first install you see) and choose to patch a boot file. Select the one you copied to your phone. Connect your phone to your PC and copy the patched boot image to your PC. Put your phone in fastboot (download) mode and flash the patched boot.img file to the boot partition. Just boot your phone up. Magisk should show up as installed.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Trace.Oneil:
Thank you,is there a tutorial somewhere on this process? I am not sure what commands to type in adb to do this. I dont root etc often so i need to follow a step by step please. Also,where do i get the boot.img for Lineage? In the zip file i downloaded?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Or simply sideload the magisk apk in recovery. I know that's not the suggested way but its patching your boot.img automatically.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Trace.Oneil:
I did try it that way,but it fails. Not sure if it is because Magisk manager is already installed or what. I will try it again and then attach a photo of the error. Maybe someone can help then?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] casouzaj:
With your phone connected to your PC in download mode, launch a command window and enter:

fastboot flash boot magisk_patched.img
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Trace.Oneil:
There you go,not sure what is causing it to fail.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
I did it that way by installing from adb. Just adb sideload Magisk apk. Where did you got the zip file from? From the official github source from john?

EDIT: https://github.com/topjohnwu/Magisk/releases/download/v25.1/Magisk-v25.1.apk
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Trace.Oneil:
Yes,got it from github
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] remunramu:
Just flashed. Its smooth, good and snappy. So, Gcam wouldn't work with this ROM, any rec for good camera app? the preinstall camera sucks.

Also the display always revert to srgb everytime I changed wallpaper which is kinda bland and kinda less colorful. I still get the persistent USB debug notification despite clean install.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] casouzaj:
I use the Xperiance: camera Magisk module. It's the Sony camera. Give it a try!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Trace.Oneil:
So i still dont have Magisk fully installed. I went looking for a boot.img for LOS 19.1 but dont find it. But what i do want to add to the list of bugs or problems is one i noticed in LOS 18.1 already that seems to have carried on in LOS 19.1 and that is the sound. There is no clean stereo sound.

The bottom speaker works fine,it has decent volume. In stereo mode this is right channel. The problem is the top/left channel speaker.if you go to the accessibility menu and then sound controls and move the slider around while playing any stereo test on YouTube,you will notice the left channel volume is low.

When moving the slider to right channel all works fine,volume gets less on left channel and no output when slider is fully right. But when moving the slider to fully left side,volume gets less and both left and right speakers play when fully left at lower volume. Can someone please look in to a fix for this?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] thkthkthkthkthkthk:
I tried that here as well (xperia xz2, same error "E: Package is for product Akari but expected H8296"). So:

adb reboot bootloader
fastboot flash boot lineage-19.1-20220622-recovery-akari.img
fastboot reboot

which booted until "Sony" appeared on the center of the display, and then nothing else happened. So I tried to boot into recovery (Volume Down + Power), but the display keeps being blank after that and the phone is neither detected by adb nor fastboot. Rebooting into fastboot (Volume Up + connect USB) lets me flash the 18.1 recovery image from 20220615, after which I can boot into lineageos 18.1 again.

Any ideas?

(I only have a linux laptop here, so no Windows driver issues obviously)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Don't do fastboot reboot. This will boot up system but you have to boot into recovery directly. Just unplug the usb cable after fastboot flash, wait for the blue led to turn off und then directly boot into recovery.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] thkthkthkthkthkthk:
So... 1000 times thank you!

While the speed was slow enough to drive me nuts ;) I'm finally up to lineageos 19.1.

Thanks again for the great and fast(!) help!

USB debugging: Yes, that's because remains untouched, even on a clean flash.

hi, dtrunk90 , i have flashed ur rom but find a bug that i cannot solve it. View attachment 5622723

My device is XZ3, sov 39 from Japan, which has been unlocked bootloader.

It can connect the LTE Internet and recive SMS while the calling is unavailable. As you can see, the signal bar has an exclamation mark ! so i cannot call with others and others cannot call me, either. Then, i tried reset but still failed.

So, do u have any advices?
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Jp models are not supported. The exclamation mark means there's no mobile data/internet and has nothing to do with calls at all. The bug about not getting a notification (only the ringtone) for the first incoming call after a clean flash is known.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] kumamon2000:
Thank ur reply , dtrunk90. Now, i have sloved this problem by reseting again and again. Finally, the call can work even if the signal bar still has a ! .
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Official builds are now available!

In order to switch from unofficial to official builds a clean flash is required. Please refer to the official installation guide on how to clean flash properly.

Hi,

Glad to see Lineage 19.1 is officialy coming to our XZ3. I'm currently running Lineage 18.1.

Well, I got an issue, when trying to upgrade (sideload way) : "Package id for product akatsuki but expected H9436".

It's unexepected, my phone is a 9436 (akatsuki), and I'v been updating (software way) Lineage 18.1 every week for monthes without trouble ...
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] ak101ss:
Exactly same method used and same issue faced here too. Any suggestions are welcome.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
It's on my todo list
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
TA partition will be deleted. You can make a backup if you want to switch back to stock rom some day. Restoring that partition will lock your bootloader afaik. And locked bootloader with a custom rom will likely result in a soft brick.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
I'll have a look later. Some ppl also faced that for XZ2C. It's weird because I don't had such issues on all of my tama devices. Which recovery and version of recovery are you using?
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] ak101ss:
Using LOS Recovery, 18.1 (20220610) here.

Writing 'recovery' FAILED (remote: 'No such partition.')

I think I should do "fastboot flash boot lineage-19.1-20220617-recovery-akatsuki.img" instead... and then reboot to recovery ?

By the way, I'll try this but going to backup everything before.

I have successfully in the past changed the device model and region of sov (AU) model phones via Flashtool. The only issue you may face is whether your phone is simless (without a sim card reader) or not. You can achieve this by following the steps I provided here if you are willing to experiment, but please be aware of the risks with a simless device ( I imagine that the sim #'s are stored with the IMEI but firmware for the sim card reader might cause trouble from an H8416): https://xdaforums.com/t/rom-unoffic...for-z5c-suzuran.4205135/page-43#post-86376131
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] &(*):
@dtrunk90

Have you solved the issue with the speakers? If not, @Chippa_a fixed something simular on the X Compact with the LineageOS 19.1 build he provided.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] &(*):
Your problem with flashing the recovery.img is you're writing it to the wrong partition. The command should be:

fastboot flash boot lineage-19.1-20220617-recovery-akatsuki.img

make sure you perform this command before flashing the recovery if coming from stock android 10 else if from 18.1 ignore:

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

Instructions are posted here .
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dobodu:
Well, thank you for help, I realized my mistake (boot vs recovery) !

I did not use the vbmeta.img (which one ?) but the setup ran successfully !

Edit : vbmeta.img is the one you get when you want to keep your keys from original firmware, for me, they are lost for years...
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Yeah you don't need to disable avb. All fine.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Nope, didn't had time yet. Still downloading all trillion tama roms to grab modem configs out of them. X compact is only unofficial so i can't check the sources i guess. @Chippa_a how did you solved it?
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dobodu:
So for others, here comes the step by step instruction I did to upgrade from 18.1 to 19.1 in a dirty way

(but running successfully till now, without the need to restore any apps).

1/ Reboot the phone in "bootloader" mode

2/ fastboot flash boot lineage-19.1-.....-recovery-akatsuki

3/ fastboot reboot recovery

----- Didn't worked as expected (rebooting to Lineage 18.1...)

----- So I rebooted to Recovery from the shutdown menu... Nice ! I'm on Lineage 19.1 recovery

4/ select Apply Update / from ADB

5/ adb sideload lineage-19.1-......-nightly-akatsuki-signed

6/ select from recovery home : Advanced - Reboot to recovery

7/ again select Apply Update / from ADB

8/ adb sideload MindTheGapps-12.1.0-arm64-20220605_112439

----- Got an error "signature failed"

----- So Apply anyway

9/ select from recovery home : Reboot system now

10/ Wait...

11/ Cheers your on Lineage 19.1 !

Of course, this breaks the root behaviour, you need to go to recovery and flash the latest magisk.zip

to gain root access again.

Hope this will help ;-)
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
Instead of step 3 simply disconnect the usb cable and wait for the blue led to turn off, press volume down + power to boot into recovery
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
Hello guys, congrats @dtrunk90 for keeping the XZ3 alive with the latest android versions!

I want to ask either you or any other of the users here, what would you guys recommend for using as a rom these days on the XZ3 (daily driver)? Coming from OPO, I have been disappointed for the lack of support for the XZ3 (even though with project treble, I thought it would gain much support) and lately the stock rom asks too often for factory resets (2-3 months).

As far as I understood, the biggest downside to switching to LOS 18 or 19 is the camera getting crappier? That's a huge downside tbh.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
That's not a downside of switching to LOS but more a downside of unlocking the bootloader. No matter which custom rom you'll use, you'll lose the DRM keys. There are camera apps who can do good enough photos/videos though. At least for me.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
****ing sony man. Playing pretend to be so open to custom roms and stuff...

Okay, so othat than that how's the general use what's the best rom for the XZ3?
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
I guess they want to somehow secure their stuff from getting hacked/copied. It's not just Sony. Samsung at least tried to be even more bad. They initially killed the camera on their Z Fold 3 once bootloader is unlocked. After some complaints they finally row back. But still, also other manufacturers are doing that.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
Oh wow, didn't know that. And project treble is a fail right? (with easily switching between roms)
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
@dtrunk90 Oh and you didn't answer a couple of times, what's the best rom for XZ3 as a daily driver 😅
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] dtrunk90:
I didn't answer because I can't give an answer to that. I'm using my own Rom. What answer do you expect? 😂 It's a thing of personal taste. Use whatever you want.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] Alex5699:
this is bands limitations you have to change to 2g/3g to make and receive calls with slow internet. Unless you know how to unlock all bands, this is the best it can get
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
Oh damn, I am willing to help the development guys.
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] Alex5699:
This is actually not a rom issue, this is your phones limitations because Japanese uses a different frequency. Have a look here
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
This happens only at the Japanese versions? European should be okay?

Yes UK and USA and international are fine but japanese phones .. always issue trust me I know .. I have a Japanese xz3 using right now lol
[Sony Xperia XZ3 ROMs, Kernels, Recoveries, & Other] duckwind:
