By the way, I already made a backup of my whole device with TWRP recovery and saved it on my SD card

I downloaded TWRP img file from https://dl.twrp.me/pollux_windy/ on my computer then booted my tablet into bootloader mode

Ran command fastboot.exe devices >> showed my device name

Ran command fastboot.exe flash boot twrp-3.3.1-0-pollux_windy.img flashing was successful

Ran command fastboot.exe reboot

I do not see the point of flashing stock ROM as I already wiped everything on my device and removed encryption.

Could you please elaborate on the necessity of this step (flashing stock ROM)?

I will try to flash TWRP via Official TWRP app from Google play store instead of fastboot method

Should I remove current TWRP first or make Official TWRP flash and overwrite the current TWRP?

Even though, I have a feeling that this step is unnecessary because the TWRP img file is the same whatever way I use to flash it via fastboot or via Official TWRP app
[Xperia Tablet Z Original Android Development] enigmedark:
Oh , well you should not install TWRP as a boot image, so it always takes you to recovery and not to the system, that way of flashing the recovery does not work on this specific tablet.

You can try flashing this twrp:

https://xdaforums.com/xperia-tablet-z/orig-development/ub-twrp-v3-2-1-xperia-tablet-z-t3735110

After that install rom and gapps.

Flash stock rom can fix problems in all partitions because you you replace everything with the original factory version even recovery or others what might be causing the problem.

Ghost touches

Once in a while, the screen will spazz out , registering phantom touches everywhere and making the tablet unusuable. Oddly, it goes back to normal when I turn the screen off.

I've attached a log cat to see if someone could identify what the problem is. I know the device is really old so it may be due to aging hardware.

Thanks

I can confirm the behavior of the not working nav bar. Every time the Keyboard is open I can not use the nav bar. It doesn't matter which key i press the home button is highlighted but nothing happens. After closing the keyboard it works fine.
[Xperia Tablet Z Original Android Development] lm089:
Strange, not here on my device.Tried with both standard Android keyboard and SwiftKey.

What's still buggy is the fact that any extra nav bar button like the keyboard switcher is pulled to the center and therefor is overlaid by the home button and cannot be used (I posted that a while ago in this thread)
[Xperia Tablet Z Original Android Development] lineagefan123:
With the November build I recognized that if I start a connection with the Real VNC Viewer app, the device (pollux windy) immediately restarts. I've done it twice now to check whether it's reproducable.

This problem existed already some months ago, then was fixed, and now is back again :D

When goes official? 15.1 went in December 2018...
[Xperia Tablet Z Original Android Development] Rootk1t:
Just to clarify the state of things a bit.

There is still no solution on fixing some issues on LOS 16.0. It takes a lot of effort to implement new features from the latest releases of Android due to the plaform (fusion3) being rather outdated now, few developers are working on it, even less still have real devices "on hands". So i'd rather better be mistaken, but 15.1 may be the last official nightly to be presented on LOS website.
[Xperia Tablet Z Original Android Development] lm089:
Sad, but somewhat to be expected. Let's hope that our devices receive at least frequent security updates I can live with that

Good opportunity to once more thank everyone involved, you know who you are! :good:

RR team stopped adding the latest google security updates to it's 9.0 in September, as the moved their effort to Android 10.

LOS was updated till the end of 2019. I hope, that they will continue to merge latest security updates for some time in the future, as they have a good record of updating even old ROMs like LOS 14.1 which was still receiving updates.

Arrow keys in portrait mode

Hello,

I just upgraded from official LOS15.1 to this rom. It's working nicely so far but one issue with LOS is bugging me since 15.1 and it's not solved with 16.0.

When in portrait mode and with activated arrow keys, both arrows seem to rest on the middle button of the navigation bar (barely visible). Any tap on the navigation bar activates the middle button but nothing else happens. In landscape mode everything is fine.

Something similar is described here: https://gitlab.com/LineageOS/issues/android/issues/621 but the provided solution (changing the smallest width to 612) doesn't help.

This doesn't seem to be specific to this build but an overall problem with LOS on devices with bigger screens. I never had such problems on smartphones. Any ideas what to do or where to adress this bug properly?
[Xperia Tablet Z Original Android Development] Rootk1t:
it's good that you reported it there. There are greater chances for it to be fixed.
[Xperia Tablet Z Original Android Development] csoller:
I havent noticed this bug although im still using the december build.

A bit of sad news today.

As i predicted earlier. LOS 15.1 was the last official nightly released for our device. Builds are no longer released. Status of device (and others on the same platform) moved to "Not maintained".

So grab the latest official nightly builds and stick to them for stability reasons, or continue using still updating unofficial LOS 16.0 builds, which i hope will still be released while LOS team continues to merge monthly google security updates.

Still no 5ghz WiFi on my pollux...

Anyone else with pollux having same problem?
[Xperia Tablet Z Original Android Development] enigmedark:
I try with a 5ghz wifi (normally I use 2.4 for the bad internet in my country) and I can see and connect to the wifi without problems on pollux_windy.
[Xperia Tablet Z Original Android Development] L.F.B.:
thanks for your feedback.?

I really want to know anyone with pollux have the same problem.

I think its only pollux related. maybe its because of a different radio chipset.

Hi,

today I updated Magisk to the new version, rebooted, the desktop appeared and than the tablet rebooted, but didn't start the device anymore, after a long boot animation ended up in Twrp.

I deleted magisk, flashed the current Rom version, cleaned cache, the tablet doesn't boot LOS anymore, after the los boot animation, always TWRP starts.

Any idea?

Thanks
[Xperia Tablet Z Original Android Development] enigmedark:
I have that problem many times in the past with magisk, sometimes for updates, sometimes for modules. The only way that works for me is doing a new clean flash of the rom and I don't use magisk on tablet anymore, I use lineageOS root now.

I'm on pollux_windy and can't see 5ghz WiFi.
[Xperia Tablet Z Original Android Development] lm089:
Not here: also pollux_windy, but I'm constantly hooked up to my 5GHz WiFi network at home.

Chances are that not seeing a 5GHz network could have to do with the channel chosen by the router.

You may want to try setting your router to use one of the lower channels usually below ch 52). The higher channels aren't available in some countries, and some Lineage ROMs don't accept them at all even if they are free to use in your country

Hi

I have the Lineage 15.1 ROM today on my SGP311.

Everything works well.

I tried to flash this ROM (after a full wipe) but the tablet doesn't boot anymore after the flash.

Could someone help me to understand what I've missed ?

I'd like to install this 16 ROM

Hi,

a big thanks to [MENTION=7827892]CaHbKaUp[/MENTION] and all people involved in this great ROM, very good job guys !

I have the pollux_windy version of the device.

I have installed this ROM with Magisk 19.3 then upgraded the latest 20.4.

I have installed Open gapps pîco version and then Vanced.

But i can't login.

Any suggestions ?

By the way, should we use addonsu from lineageOS or Magisk is just fine ? And there is no Xposed from Magisk 19.3 or 20.x upward ?

Thanks a lot for your answers !

Hi lm089,

[MENTION=4149551]lm089[/MENTION] can you please tell me what is exactly your install since we have the same device...

Mine is LineageOS16 + Magisk 20.4 + TWRP fota ilstall manually but Vanced doesn't log in anf Xposed is not installed.

Maybe i can try duplicate yours so that everything works ..

Thanks
[Xperia Tablet Z Original Android Development] lm089:
Hi, I don't use Vanced or Xposed. Other than that it's apparently the same as your setup:

LOS 16 (= latest verion from this thread here)

Magisk 20.4

TWRP installed to FOTA partition

The tablet is running reliably, but it's quite slow I'm afraid. Not sure whether it's the ROM itself, but I don't think so. Must be one of the apps I'm using but to date I couldn't find out which one.
[Xperia Tablet Z Original Android Development] yakupA:
Okay finally got Vanced working (with the login i mean..) by installing the non root version + microG_Vanced_dedicated.

So till now i have twrp 3.3.1 on FOTA + LineageOS16 + Open_GApps_pico + Magisk 20.4 + Vanced 15.x with dedicated Vanced_microG + all my personnal apps seems to be OK till now ..not tested that much i have to say...

Now only Xposed is kind of missing but i'm quiet scared to fall down again in the twrp loop and constrained to do a full wipe of everything ..takes a lot of time ..so i'll do a Nand_backup ...but not sure whether i'll attempt Xposed...

Thanks
[Xperia Tablet Z Original Android Development] lm089:
How exactly did you flash? From Twrp, through adb,...?

What is the exact reaction after you flashed? Error messages, bootloop, whatever?

Can you boot to Twrp or is that broken too?

You see: too many open questions. If you give details then probably someone here can help. Everything else would be just guessing

EDIT: there used to be a great and very detailed instruction on how to install LOS on the offk ial LineageOS pages. Just wanted to post a link here but had to find that pollux/Pollux_windy support pages were removed completely, which is sad.

I have owned 2 Xperia Tablet Z for years and I am still quite satisfied with them. Of course they could be faster, but in principle they do what they are supposed to.

They were still running with the Stock-ROMs, I had said goodbye to flashing alternative ROMs on my devices for quite a while. But now I dared to do it, it was quite a lot of work from unlocking, the right USB driver, and so on.

Even though these things are not as fast and snappy as current devices, they feel "like new" now, and I'm happy about the one or other new feature of the new operating system.

So I dug out my old passwords for the forum just to say "thank you"! :svetius:

have you tried making android 10 roms for this device?
[Xperia Tablet Z Original Android Development] yakupA:
Salut Zizou,

You need to format the data partition as well... that's why you're getting boot issue.... And don't install Xposed not supported on this ROM at least but Magisk is working well..

Do NOT FORGET TO BACKUP your data partition before formating since you will lose everything and don't come to cry here..

I have first installed twrp then lineageos then picoG apps (minimum Google apps) then Magisk, then vanced non root with its own microg from vanced . app ... Et voilà le travail

Hope this helps

I'm not sure if others had the same experience and maybe I just did something wrong, but when I wanted to update the ROM on the tablet through TWRP I got error 1001 (Error E1001: Failed to update system image, ERROR 7).

I had rebooted into TWRP wiped cache, dalvik/art and system and then proceeded to flash the new ROM (from the zip). I resolved it by in TWRP going to advanced > terminal, then create /cache/recovery with:

mkdir /cache/recovery

I got these instructions from this thread:
