[Xperia Tablet Z Original Android Development] Rootk1t:
It was a more of a proof of concept build to check it's possible to run LOS 18.1 on our device.

It boots, but it's not in the state of daily usage.

It's not my build and i was asked not to share it at least for some time.

Though after fixes of some major issues, i suppose it can be shared, but no ETA.

Magisk v.24.3 is not installing properly ("unable to find image to patch" or unable to mount system in TWRP) due to some internal changes. I reported this issue to developers on Magisk bugtracker in march, but i'm not sure that it will be fixed, but will see with the next Magisk release (or canary).

Boot.img can be patched with v24.3 and then flashed via TWRP, but after that i experienced different glitches and was unable to enable Zygisk in Magisk.

So i will recommend sticking to v24.1 for now as it's a fully functioning version without any issues.

MagiskHide_Props_Config and riru are not needed to pass safety net.

I happen to pass it only with enabling Zygisk and configuring DenyList on Magisk v24.1 or with MagiskHide in prior versions.
[Xperia Tablet Z Original Android Development] Rootk1t:
I share you opinion about our device.

Though things that distract me: long app installation due to very slow internal storage and insufficient RAM which leads to killing apps, as only browser with several tabs can consume all available RAM.

Though for slow paced usage (reading of books, casual games, watching movies, some photo editing, light surfing) it's quite ok. Battery life is also good, though it depends on how many cycles battery had during it's lifespan, so mileage can vary.

BTW, can your share your Kernel Adiutor settings (like what governers are you using for CPU&GPU and maybe some storage tweaks if you have them)?
[Xperia Tablet Z Original Android Development] lm089:
Thanks for picking that up. Totally agree that 24.1 is fine enough version
[Xperia Tablet Z Original Android Development] lm089:
Sure, but I'm afraid that my knowledge re: these things is very basic.

All in all I was looking for longer charging cycles combined with better responsiveness.

Main thing I did was pushing cpu frequency limits on both ends: up to 1782 and down to 192MHz. The upper limit indeed has some effect. I chose the lower end hoping to have some extra battery savings in near-idle situations, but I don't know if that really is doing any good. I leave it there anyways.

For CPU governor I chose "ondemandplus" after experimenting a bit. I feel that it suits my purpose.

GPU-wise I also pushed max speed up to 487MHz.

In regards to storage I didn't do much. Just chose the "aggressive" profile for the low memory killer. But I did that only recently so there's no experience yet.

That's it basically, at least in the kernel area.

On my hunt for longest possible charging cycles I also experimted with WiFi settings, like using an app to switch off Wifi shortly after screen goes off. That sort-of worked, but I found that the device had big problems getting into gear after longer standby periods. So I gave up on this, and since then my tablet is really quite responsive.
[Xperia Tablet Z Original Android Development] Tomek0000:
Ritu was for older magisk and safety net universal. I know , magisk hide is not need everytime but I use common procedure for all my devices and do not have to use all installed apps.
[Xperia Tablet Z Original Android Development] Tomek0000:
I do not see any time needed by tablet when I start it from standby to be full responsible. It seems to be full ready at once.

Fresh Los needs only 0.1% battery/hour in deep sleep. When I added my apps it increases to 0.16 and it is very good.

This 5 days is a time of working with LCD turned off? My observation is a using much battery with LCD on and it is not comparable with other devices. But battery is enough for charging only once a day.
[Xperia Tablet Z Original Android Development] lm089:
You're right, it's the same here now after I found which setting/app was causing this

:D I'm aware that this statement is very provocative. Of course, screen on consumes a lot of energy.

What I wanted to say is that even after 9 years the battery is still very healthy and can still handle 5 days and more in pure standby mode. In "real life" I have to charge it more often, of course
[Xperia Tablet Z Original Android Development] Rootk1t:
What app was causing such behaviour?
[Xperia Tablet Z Original Android Development] lm089:
WiFi automatic by j4velin. Not a bad app if I want to make sure that wifi is disabled while the device is in standby, still am using it on another device. But the tablet apparently has problems recovering from long standby periods if the app is active. Since I removed the app 5ablet is much more responsive after long standby. Drawback is a significant higher batter drain in standby. Still ok, but...
[Xperia Tablet Z Original Android Development] Tomek0000:
Is the turn on/off wifi the only problem ? You can find other apps or use any automation. I have many scripts in Automagic and the script not only turn off wifi but set battery saver after screen lock ...
[Xperia Tablet Z Original Android Development] lm089:
That's what I tested over the weekend by simply switching WiFi Off manually for 24 hrs. Apparently that doesn't have the impact that this app is having. You're right, I'll be hunting for alternatives. Automagic is a good idea, I even have a licence for it but quit using it for whatever reason... would you care to share your script(s)?
[Xperia Tablet Z Original Android Development] Tomek0000:
Ok, copy directory to /storage/emulated/0/
[Xperia Tablet Z Original Android Development] Lycidias:
Could someone please reupload this build ? Getting 502 bad gateway.

EDIT: Nvm, got the download.

Can't update mahisk 23 to newest because mahisk can't obtain the boot image via direct install
[Xperia Tablet Z Original Android Development] Rootk1t:
Recently released v25.0 works good.
[Xperia Tablet Z Original Android Development] Middle of nowhere Texas:
Could someone please reupload the most recent build (Jan 31, 2022)? On several attempts at downloading it I get redirected to ads or, worse, porn. Thanks!
[Xperia Tablet Z Original Android Development] Middle of nowhere Texas:
Thank you to all involved in releasing the September 9, 2021, version of the ROM. I have owned this tablet since 2013. It feels like a new (and faster) version of the original tablet. Thank you again for all that you do to prolong the lives of perfectly good hardware that would otherwise be rendered useless.
[Xperia Tablet Z Original Android Development] lm089:
Just tried the pollux_windy link from this post, appears to be working fine, though I didn't really download it now. I no longer have the zip file on my PC, I should have it somewhere on one of my external archive drives. If you can't get it elsewhere PM me then I can go looking for it

[Xperia Tablet Z Original Android Development] Tomek0000:
I lost wifi after some days of power off my z tablet. I read it is known problem without solution. Ok. I reinstalled this Los an realized, it can not be NOT rooted. Clean Los with pico Gapps does not let to install Netflix...

I used magisk the newest 25.1 and no problem with this. Safety net fix and fingerprint change do the work.
[Xperia Tablet Z Original Android Development] norabitox:
hello everyone

I turned on my tablet today for the first time in a while.

wifi is not working.

Please tell me the solution.

Regards.
[Xperia Tablet Z Original Android Development] Tomek0000:
Problem is not deterministic. You can have it or not. You can reinstal LOS or install previous where people did not report it.
[Xperia Tablet Z Original Android Development] norabitox:
thank you for your reply.

I just installed lineage-16.0-20220131-UNOFFICIAL-pollux.

But I can't fix it.

Next I will try a clean install.
[Xperia Tablet Z Original Android Development] lm089:
Over the last week I had an issue which may or may not be related to the lost wifi flaw:

after the tablet was off over a weekend (due to low battery), the tablet no longer showed any notifications (like new email, chat messages, GSam bettery status etc.). Wifi was active though, no problem browsing or sending emails etc. But playstore wouldn't load any updates, and background synchronization didn't work either. I rebooted several times, cleaned caches etc, but no luck.

This morning I restored from a Nandroid backup taken a month ago, and now anything is working now as expected. Maybe also helps in case of the lost-wifi issue?
[Xperia Tablet Z Original Android Development] lm089:
Hi, don't get me wrong, please: not asking for anything. Just curious to know whether to expect some more security patch mergers in the future, or whether the device now will stay as it is
[Xperia Tablet Z Original Android Development] Rootk1t:
Hello!

The main reason for LOS 16.0 buids are not being updated is that Google stopped providing security updates for Android 9 Pie, so nothing to merge in this regard.

LOS team marked LOS 16.0 (and even 17.1) as Unsupported.

LOS versions that are receiving security updates are: LOS 17.1 (not for long) , LOS 18.1 and the newest LOS 19.

So speaking for LOS 16.0 on tablet z, i think it will stay as it is.
[Xperia Tablet Z Original Android Development] lm089:
I thought that was the reason. Sad but cannot be changed then. Many thanks for supporting the device so far!
[Xperia Tablet Z Original Android Development] ze7zez:
It is possible to use a different way to patch android, as @M4Master96 showed when releasing android 7.1.2 ROM for deb/flo/armani/N7100 with unofficial updates from July 2022. Read all this post:

Hello everybody!

I flashed my TabZ LTE years ago to this LOS Build (the one of this Thread I think).

It shows as build number: lineage pollux-userdebug 9 PQ3A 190801.002 eng.cahbka.20200415.114900 test-keys

Is it safe to update to the latest pollux build from rootk1t?

Thank you!

Kind regards

[Xperia Tablet Z Original Android Development] Rootk1t:
Don't worry. It's safe.
[Xperia Tablet Z Original Android Development] miss_barfin:
hi, thanks for the updated security patch, however i have an issue, i have no internet connection, i can use adb shell on my pc and ping websites and it works fine but the apps themselves have no connection, i tried with the stock los browser and firefox apk from fdroid, they both only open http websites and local web interfaces like my router

https websites in stock los browser don't bring up anything and in firefox it gives this error: "This website requires a secure connection"

i have no idea what's stopping it from using SSL, if there is any log or something that i need to send you, pls tell me, this is a perfectly good tablet that i can use if it wasn't for this issue
[Xperia Tablet Z Original Android Development] Rootk1t:
Hello!

This behaviour usually means something (wrong setting or misconfigured app) interferes with internet connection.

1. Try checking that time and date on your device are set correctly.

2. Disable antivirus or any security software (adguard) that checks https traffic installed on device and try again.

3. If it doesn't help try resetting your device.

4. If it's still doesn't work, i can suggest reflashing LOS.
[Xperia Tablet Z Original Android Development] ze7zez:

Hello All,

Thanks a lot for having kept alive our long live tablet :)

I have installed this custom firmware and I have a very weird issue...

Before installing it, with the stock firmware, I noticed that my screen was moving without touching anything. In fact, when I was watching TV or any other video service, the device was changing of channel on its own (!!!). More than than that, it was typing on the keyboard!

Very annoyed, I decided to upgradre my tablet by installing Lineage OS. This issue was fixed for few weeks... and now it keeps occuring...

I tried everything, reinstalling from scratch the OS, wiping everything... installing an antivirus (nothing was found). I also tried to install a custom kernel to fix any breaches and the issue is still occuring... even in the recovery mode, the screen is moving by its own... When I open the keyboard, the hacker (?) is typing xxxxxx on it 😱

Well, am I dreaming or our tablet is full of breaches and some script kiddies have entered mine... What should I do ?? (It's clearly not a screen issue... the behavior is someone touching my screen and changing channels and even typing on the keyboard etc...)

Thanks all for your help and advices!
[Xperia Tablet Z Original Android Development] guhvanoh:
Has it occured to you that you have faulty hardware?
[Xperia Tablet Z Original Android Development] freezalfa:
Thanks for your help.

Yes, of course ! :)

But the behavior seen on the screen does not seem to be a hardware issue...

It happens at very specific timeframe (like when the intruder is awake...). And changing channel (or movies!) implies scrolling and clicking the screen which a hardware failure could not do, I guess 😨

Anyway, it that somehow something possible? To get access to our tablet remotely even with our lastest Lineage version without being able to be detected by antivirus?

As I have tried everything (wiping, reinstalling etc...), I feel totally stuck as well as very surprised of this strange experience... I heard about processor breaches that could not be fixed by software updates... Maybe it could be related to this...
[Xperia Tablet Z Original Android Development] ze7zez:
Do a search on ghost touch.
[Xperia Tablet Z Original Android Development] freezalfa:
Thanks a lot!

It could definitely be that... I'll do all the advices found.

Keep you posted :)

[Xperia Tablet Z Original Android Development] dead4ngel:
Hi all. Been a while since I checked this thread.

So I take it there's no way for our devices to have anything past android 9.0? It's a shame as some apps require a newer android version.

Anyone know of anything in the works?
[Xperia Tablet Z Original Android Development] ze7zez:
Try talking to @tarkzim or @cschen, as they are both still active on the forum and know the sony fusion3 device well.
[Xperia Tablet Z Original Android Development] tarkzim:
I've built LineageOS 20 for pollux and pollux_windy with the same common trees for my Xperia Z builds,

Try it and let me know if it works.

And please use the latest official TWRP to flash it.

ROM
[Xperia Tablet Z Original Android Development] dead4ngel:
When flashing the rom zip via latest twrp should I mount anything before hand?

And in terms of wipes it's just the usual right - art,dalvik, data, sd?
[Xperia Tablet Z Original Android Development] tarkzim:
No need to mount specific stuff, and wipe system, data, caches only.
[Xperia Tablet Z Original Android Development] x52-curcuma:
Unbelievable! Android 13 is running on this old tablet!

So far everything works fine except GPS. Since scoped-storage, Solid Explorer has very slow access to external SD-card on some ROMs but with your ROM there is no access problem at all.

Some apps (ie: Swift Backup) show error/warning but work correctly anyway.

Unfortunately microG is not working (failed signature spoofing) so I went back to LOS-16 for now.

Oops, I haven't tested camera.

Thanks for the great ROM!!!
[Xperia Tablet Z Original Android Development] Lycidias:
Hey, very nice, thank you🙏

Running great so far.

One thing I noticed, I couldn't boot when /cache and /data are formatted in f2fs.

Is there any workaround?

Second thing:

I've tried installing magisk with the latest TWRP and the install succeeded.

But after reboot I noticed that I got a bootloop after the Xperia screen. It just infinitely restarts.

I tried patching the boot image inside magisk and flashed it but no luck.

When I flash the stock boot.img I got the tablet to boot normally again.

Is there any solution?

Or someone could provide a working patched magisk for pollux_windy?

Thanks
[Xperia Tablet Z Original Android Development] x52-curcuma:
I got the same boot loop problem with Magisk-26.3. Using Magisk-25.2 is fine.

My Pollux-Windy could not get any GPS fix.

Otherwise everything seems fine to me.
[Xperia Tablet Z Original Android Development] tarkzim:
Thanks so much for testing, can you please send me PM of screenshots of the rom of some major hardware features like lte or nfc settings, also let me know more detailed about what's not working.
[Xperia Tablet Z Original Android Development] x52-curcuma:
Please find the attached. These are GPS fixed with LOS-16.

Even after hours later GPS not fixed (zero signal) with LOS-20
[Xperia Tablet Z Original Android Development] dead4ngel:
Do we need gapps as well?

And with micro g which version are you using?
[Xperia Tablet Z Original Android Development] x52-curcuma:
Don't we need gapps for basic "GoogleServicesFramework" and others for 3rd party apps?

And there are not many options for choosing gapps for android-13 and arm-v7a.

As for microG, there are even more limited installer packages for android-13. Unless you would like to patch rom from scratch, you may want to use microG installer. For up to android 12, there are many choices but now probably only MinMicroG is updated for 13.

I used v2.11.0 and failed signature-spoofing. Maybe I should use v2.12.0 and try again.
[Xperia Tablet Z Original Android Development] dead4ngel:
What I meant is do we need to flash gapps after flashing the rom zip in twrp.

As for microg I use the latest ones that come with yt revanced.
[Xperia Tablet Z Original Android Development] x52-curcuma:
I see... Yes, that's what I did, flash GApps after flashing ROM and Magisk.
[Xperia Tablet Z Original Android Development] dead4ngel:
What gapps are you using? Since the devices are arm platform I'm only able to find opengapps which is old and from 2022.

Niks is all arm64 which won't work.

Anyone got links for arm platform but one that's up to date? Just need core package.

[Xperia Tablet Z Original Android Development] robjg63:
Well colour me amazed!

I have had this tablet for a very long time and managed to muddle my way through installing Android 9 (Lineage 16) a couple of years back. I don't use it too often, but it was very buggy and often crashed the launcher and did very strange things.

It wouldnt boot at all the other day - figured it was toast.

Finally worked out how to start TWRP and decided to see if maybe I could re-install Android 9.

I found the posts above from @tarkzim about Lineage 20 and decided to give it a go.

Amazing - Android 13 on this old device!

On first impressions it is running better than Android 9.

Seems quicker and I haven't seen it crash yet.

Big thanks to all concerned.
[Xperia Tablet Z Original Android Development] mateotxiki:
Amazing LINEAGEOS 20.

BiTGApps-arm-13.0.0-v2.3-CORE.zip --> working

Camera --> working

GPS --> NOT WORKING

Bluetooth --> NOT WORKING

Thanks tarkzim.
[Xperia Tablet Z Original Android Development] reip:
OMG

Installed it right away on my pollux, went smooth with bitgapps (arm version)

The rom is not the fastest, but it's more stable than the pie build. I can confirm GPS (I don't care) and bluetooth (bummer) don't work, but after an hour of testing I haven't found any more significant bugs except screen recording doesn't work with internal audio. LTE seems to work fine.

@tarkzim Are you planning to develop this build further? So many thanks for having this device resurrected!
[Xperia Tablet Z Original Android Development] tarkzim:
Yeah, I have plans to support it with a dedicated thread, but without device in hand I can't test it easily,

So can you be the tester and let me know if you have interested in it, PM me for private contact info, thanks.

And last, I'm not sure about Camera HAL1 support on Android 14, but I will focus on A13 first.

Yes, Bluetooth works! But GPS is not.... After nearly 1 hour "0" GPS signal, while LOS-16 locks in 13 GPSs out of 22 in less than 5 min inside house in heavy cloud weather.

Besides, Android 11's Scoped Storage is making this rom less attractive than Android 9.
[Xperia Tablet Z Original Android Development] MikeViller:
more attractive to test would be based on Android 12 or 12L which Google made the first version of Android for tablets. But being my everyday tablet I need Netflix to work and headphones or Bluetooth earphones the rest are not needed for me. I use the tablets as a reader and look at movies when traveling.
