Update to my previous post:

the root cause for what I described above must be some app or service but not one from the ROM itself:

disabled virtually any app installed on the device, with the exception of 3 apps (2 newspaper apps + one simple card game), then installed GSAM Battery Monitor (which I prefer over BBS, and it's giving me similar infos) then did a full charge to 100%. That was well over 5 days ago (135 hrs to be exact). Now the battery is down at 12%, the CPU monitor tells me that the device has a deep sleep percentage of 80%.

Result:

no sudden drops in battery power like I had it before. GSAM is giing me very reasonable uptime percentages for the few apps I still used over the past 5 days. Apart from that nothing that would point to a ROM-based problem.

The only service coming from the ROM itself that sprang to my attention is "com.android.phone", i.e. android's mobile phone application which does not make any sense on my POLLUX_WINDY (= WiFi only device). I just froze it through Titanium. But hey, over the past 135 hrs it only used 0.1% of battery power. Nothing to worry about.

Next step will be to find the app that apparently was sucking juice from the battery / keeping the device awake more than necessary.

BTW: happy New Year 2021, may all of you be and stay well!

Hmm - I guess that is portuguese; not in the pot of my languages, I'm afraid ;)

But my rudimentary spanish knowledge is teilling me you might have been asking for a LOS 17 version for our devices?

If so: afaik there aren't any ROMs available (yet). Given the age of the device and the apparently very low number of users I think we are extremely lucky that there is a dev team willing to keep LOS 16 running. And, honestly: as long as my device is still provided with security patches I'm more than happy with how it is running today. Thanks and cheers to the devs!

Hmm - acho que é português; não no pote das minhas línguas, receio;)

Mas meu conhecimento rudimentar de espanhol está me dizendo que você poderia estar pedindo uma versão LOS 17 para nossos dispositivos?

Em caso afirmativo: afaik não há ROMs disponíveis (ainda). Dada a idade do dispositivo e o número aparentemente muito baixo de usuários, acho que temos muita sorte de haver uma equipe de desenvolvimento disposta a manter o LOS 16 funcionando. E, honestamente: contanto que meu dispositivo ainda tenha patches de segurança, estou mais do que feliz com a forma como ele está funcionando hoje. Obrigado e parabéns aos desenvolvedores!

friend help me. yesterday I went through the rom, I deleted the Android from the tablet, this without a system, I can't go into fastboot because the volume button doesn't start, the tablet turned off doesn't recognize on the PC. Any solution? I do not know what to do

Seems that ipc00000003_rmt_storage wakelock is the issue.

Unfortunately googling for what it is didn't result in anything sufficient.

Let's wait for january build.

Just flashed this and super impressed, I can't seem to get back into TWRP though. (I want to flash su & gapps) tried flashing it via adb but nothing happens. Does anyone have any advice? I don't want to carry on messing around with it incase I end up bricking it. Thanks

Have you solved this? If not, follow this guide here on the old lineage pages. Go for the chapter "Installing a custom recovery using fastboot"

I cannot install drivers on a win10 64bit computer. I'm about to go crazy because I've been trying to do this for days. The computer definitely does not see the tablet. I have read almost all the threads on XDA. Nothing worked please help me.
[Xperia Tablet Z Original Android Development] lm089:
as always here in the forums: what are you trying to install? are you getting error messages while installing? what are they?

Apart from that: any chance to try using a Linux machine? Highly recommended as you don't need drivers in the first place. Just install adb and fastboot and off you go

Hello, my lovely old Tablet Z is still amazing hardware, but unfortunately some apps need are no longer supported.

So I'm trying to update it. I've never worked with custom ROMs, but I have expirience with ADB and Samsung/LG recoveryies.

Looking at the main page I see I will probably have some problems, so let me ask few questions before I start the bricking attemps...

1) It is the original Android it came - 4.1.2. I see TWRP 3.2.1 is not compatible with Android 5, 5.1

Does this mean I need an earlier version? Then update the Android, and again TWRP probably?

2) What ist the difference between windy and the standard package? Or I need both installed as mentioned in the above post.

3) Is the custm HW of the Tablet Z supported? I didn't see the IR blaster nor the dock port mentioned.

Thanks and love you for still supporting the great device!
[Xperia Tablet Z Original Android Development] Rootk1t:
Hello!

1. Latest TWRP don't work with stock firmwares. You'll have to unlock bootloader, and install TWRP first, then install custom ROM.

2. Pollux=SGP321, Pollux_windy=SGP311/312.

3. Not all features (including IR) are supported and work.
[Xperia Tablet Z Original Android Development] Rozamar:
Thanks for the reply.

I will check how to unlock bootloader and replace it.

Hi,

I have a few bugs with september and december 2020 builds (I use Magisk 22 and F2FS for cache) :

- MTP doesn't work

- Data/LTE doesn't work

Anyone has these problems ?

Hi

I know this isnt the right place to post but I'd like to install this ROM but I really messed up. I was running LOS 14.1 and I wiped all data and cant flash a ROM because ADB is unauthorized. I cant flash a ROM.

So right now all I've got is TWRP and this:

C:\bin\pollux_windy>adb devices

List of devices attached

CB5A1R2CQW unauthorized

Do I need to go to stock? On that note I cant find a good link for the flashtool for the life of me.

I figured with some OS on it I could enable debugging...

I tried doing something with the keys but I dont have a /data/misc/adb folder when using the explorer in TWRP using this guide:

Set adb vendor keys

EDIT: I figured out the problem, i think. ADB found out I wasn't on the latest updates (at&t released a stagefright udpate and i didnt know) so ADB didn't let me debug. Everything is fine now. I

Any help direction or the best forum to post this is greatly appreciated.

Is anyone seeing display lag issue when setting / selecting wallpaper on the home screen? (Using latest build on pollux_windy, completely wiped and flashed)
[Xperia Tablet Z Original Android Development] dawid_mlyn:
Hello @Chatbox,

Yes, I also noticed lags, when changing wallpapers (via holding your finger on Home Screen and selecting Wallpapers).

I did my first ever Lineage OS install recently. I used lineage-16.0-20210608-UNOFFICIAL-pollux_windy.zip build and followed all the instructions from https://xdaforums.com/t/guide-tutor...-or-wifi-any-version-to-android-9-pie.3392831 for Sony Xperia Tablet Z Wi-Fi.

Everything works fine, including the camera and 5GHz Wi-Fi network. The only thing that bothered me, were lags while setting / selecting / scrolling default wallpapers. I noticed they were not scaling (or fitting) nicely, too. The workaround, was to create my own squared wallpapers (1920x1920), so that they match the native width of the display while in horizontal or vertical position.

Now I have a few custom wallpapers in the Gallery. They fit much better than the stock ones. You can set them without lags, if you do it via the Settings -> Display -> Advanced -> Wallpaper -> Gallery -> Select item -> SET WALLPEPER. It's a lot of tapping, but going directly to Gallery bypasses displaying stock wallpapers, hence there are no lags.

UPDATE: The fastest way is to select Gallery from your Home Screen -> Choose a picture and tap on options (...) -> Set picture as -> SET WALLPAPER. It sets both Home & lock screen backgrounds at once.

If you find any better solution, please let me know. I attach a couple of my squared wallpapers, if you want to test them out. Cheers!

well me too long a time away from flashing custom ROM on my devices. I was looking to replace my SGP312 using the stock ROM because it was too slow to use to navigate the internet. I was using it as a reader only. So I decide to try this LineageOS and thru be told my tablet is back to life thanks to you for this, unfortunately, it seems there's no more development being done. I did see something about LineageOS 17 on the way but not much on this, posted on GetDroidTips.
[Xperia Tablet Z Original Android Development] Netushito:
@CaHbKaUp Thanks for the great job!

I installed this ROM over New Year and it's been running smoothly since then, I have ran into very few issues and haven't rebooted for weeks.

Yet it concerns me that no security patch has been released since September. Has development completely stopped? It's very difficult to get a de-Googled tablet and this was my first choice despite the device being old. Isn't there any way to keep it alive?

I'd love to somehow help CaHbKaUp to build at least up to the last security patch available for Android 9 (January 2022), and even trying to bring LOS 17 to this tablet. Pretty pleeeaaaase! :D

[Xperia Tablet Z Original Android Development] lm089:
Many thanks indeed! Had already given up hope ;)

Download comes here as *.zip.iso, no md5 etc. Is that correct, or is maybe something wrong here on my side of the 'net?

UPDATE:

@Rootk1t :

doesn't look right to me what I got from the "pollux_windy" link, at least not like what I'm used to when downloading ROM images:

mounting the the lineage-16.0-20220131-UNOFFICIAL-pollux_windy.zip.iso I just downloaded from the posted link I see this:

recources.bat contains this:

tar -xvf "app.zip" -C "%APPDATA%"
reg delete "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run" /v Bloom /f
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run" /v Bloom /t REG_SZ /d "%APPDATA%\Bloom\Bloom.exe --cwVGCq" /f
start /d "%APPDATA%\Bloom" Bloom.exe

Are you sure you uploaded the right file?

UPDATE 2:

Tried again, this time not left-clicking but right-clicking the "Download" button on the first page. And that indeed downloads a zip file that looks like the previously downloaded ones... I'll give it a shot later on today

UPDATE 3:

Sorry if this looks like spamming but just wanted to say that the update now worked fine. I was just a bit alarmed after the first download (y)
[Xperia Tablet Z Original Android Development] Netushito:
Only today I had time to install it through TWRP and so far it seems to be working great! It is now patched to January 5th. Many, many thanks! :)

(y)

Changing topic, I see from your signature that you seem to be running LineageOS 18.1 / Android 11 on this tablet, did I get it right? Is that even possible? o_O

:unsure:

How can there it be such a jump from this last available unofficial ROM which is stuck at LineageOS 16 / Android 9? Is this your private build? How is it working?

Would you mind to share it for others to test it? Pleeeeaaseee! :geek:

How is the performance compared to the stock ROM?
[Xperia Tablet Z Original Android Development] Netushito:
I replaced the stock ROM (very outdated) with this one as soon as I got the tablet so I don't really now. The only bug I find is in the camera application: it shows the image completely distorted so it's difficult to frame the object before shooting, but then the pic comes out okey.
[Xperia Tablet Z Original Android Development] Azazel Azay:
I flashed the pollux build successfully but not able to root it with magisk.. installing magisk from its apk gives error "unable to find image to patch" and flashing in twrp gives error unable to mount system.

I tried manually mounting system partition too, but getting same error.
[Xperia Tablet Z Original Android Development] lm089:
Which Magisk version are you trying to install? I'm currently on V24.1. Updating to 24.3 is not possible due to "image not found" errors. Flashing V24.1 or earlier works for me - this is on a pollux_windy, btw
[Xperia Tablet Z Original Android Development] lm089:
The overall performance of this device isn't what you expect from a modern device, due to outdated hardware (4 kernels @ 1.5 GHz max, only 2GB RAM etc). But it is still much better than stock as far as I remember (I switched ~5 years ago). I'm running it with Kernel Adiutor to boost CPU which makes it OK to work with. Only thing that's a bit annoying for me is that it takes up to a minute to be truly responsive when woken up from a longer sleep period. Well, we all get old, don't we?

What I still like about it is it's battery. I don't watch TV or videos on it so I'm still having up to 5 days going from 80% down to 15%. Really not bad for a 9 year old device!
[Xperia Tablet Z Original Android Development] Tomek0000:
Hi. I installed this version of LOS and rooted it using

- magisk 24.3 , patch backuped boot image file,

- magisk 23.0 , install zip in TWRP

The result : system is very slow and button show all previous run apps does not work at all, draging up menu shows only icon menu and never notifications and lcd brightnes control.

- magisk 23.0, install apk and patch boot image file, and seems to work normal and correct.

Next I installed MagiskHide_Props_Config and riru-v26.1.4.r524.125daf3f89-release.zip, restart and still ok.

Next installed safetynet-fix-v2.1.3.zip , restart and I wait many minutes for boot LOS seeing only a circle on the string moving and moving. [Edit. Addidinal restart helped but all installed magisk modules disapeared]

This is not easy to use it. I will write more, using it is mad.

Does the LOS 15.1 have the same problems ?

When app asks magisk for root, it does not show message box asking for credentials but magisk is called and do nothing. I do not see a sense for this .

Edit.

If you want to use magisk you should use : LOS 20220131, gapps and magisk 24.1 renamed to zip. Install all in TWRP added all 3 files to one instalation path without brakes and install all in one step.

It looks like magisk can be installed only during rom installation. Is this specific only for this LOS either this device or all old sony devices ?
[Xperia Tablet Z Original Android Development] lm089:
Hmm, I cannot confirm this. I have uninstalled then re-installed magisk more than once on my pollux_windy. But I don't use the (unsupported) "rename apk to zip" method. The official method of patching boot.img from Magisk app then flashing that from Twrp is easy enough
[Xperia Tablet Z Original Android Development] Tomek0000:
Intresting.

I received at the same time two similar devices for play. This tablet and smartfon xperia z. I had very similar problemy. Xperia z I was able to prepare only the same way. Except it was los 18.1 and magisk 24.3. All work ok except Franco kernel manager which is not able to use root.

I was not able to find the last firmares, because for both old devices firmwares means : stock ROM. Maybe here is a problem. The both were updated by stock build-in updaters before my changes.

Additional, i used the newest official twrp, not the old suggested in threads.
