Hi,

which one is the fastest in your experience?

IT IS a android 9.x pie build,what do you mean that this rom 'more stable than the pie build'?

Others have GPS and BT work,is it true?any way of fixing it by clear cache,data?
[Xperia Tablet Z Original Android Development] Rootk1t:
In this thread it happened that LOS16/LOS18.1 and LOS20.0 builds were shared.

The most stable with pretty much everything working is LOS16.

LOS 18.1 and LOS20 have some issues with GPS (LOS18.1) or BT (LOS 20) not working.

That makes sense, x52-curcuma. Now in the right thread...

I replaced the sd card, now I dont' have issues with it anymore. So maybe the old one was faulty or simply too filled up.

As for GPS: I have no problems getting a fix. It's already quick and stable without modifications. I was thinking of location services that rely on Wifi or the mobile network when GPS isn't available. This isn't working but the reason may be this: https://github.com/mozilla/ichnaea/issues/2065. Mozilla is phasing out its location service right now.

Hopefully there will be an alternative in the future that will be implemented in MicroG. For now it seems to be GPS or no location at all.

Other than that, I'm really satisfied with the outcome. Thank you for your input! Even PlayStore works and I can use Apps for which I don't have a FOSS alternative.
[Xperia Tablet Z Original Android Development] x52-curcuma:
Grad to hear that your tab works now!

As for GPS, without wifi getting the location fixed is the main issue. In my case, I've tried so many versions of roms, micoGs, system install/systemless install etc etc, even after the wipe some modules remain. So honestly I am not sure what makes my Pollux-Windy catch many GPS signals quick and accurately. Fanny thing is : WiFi on and use Organic-Maps my location will be shifted by about 670Km.

Hello, first of all thanks your work!

Any suggestion about the partitions's file system?

Currently I have with this setup: cache : f2fs, System : ext4, Data : f2fs .

Is this ok? Thanks

WIFI: Europe & Japan channels (12,13 & 14)

Does this Lineage version supports WIFI channels 12, 13 & 14?

Lineage 15.1 does not.

Lineage 14.1 does.

Thanks in advance
[Xperia Tablet Z Original Android Development] Rootk1t:
Yes, this is optimal.

It depends on a country you've chosen in android settings. Some countries prohibit usage of 13,14 channels, but it's not that difficult to unlock them.

I used this build briefly but i noticed the tablet running quite hot and battery draining quite fast, does this happen to anyone else?
[Xperia Tablet Z Original Android Development] manicmarvin:
All good with mine, only main issue is auto rotate
[Xperia Tablet Z Original Android Development] lm089:
Unfortunately it's not only the orientation that's missing: I tested all sensors using "Sensor Test" from the app store (screenshot #2), and compared the results to those from LineageOD 15.1 OFFICIAL (screenshot #1). As we can see there's hardly any sensor working, only "Light" and "Gyroscope". That means: no compass, no accelarator, no magnetometer, from the ones that have been tested positively on 15.1

I don't want to sound ungrateful, in the contrary: I highly appreciate the work that everyone is investing in their free time. And apart from the (currently?) not supported hardware this ROM feels really good. Didn't have time to learn something about battery consumption: I'm busy testing, and poking around, which leaves the screen on permanently and consumes lots of battery power...
[Xperia Tablet Z Original Android Development] stoneh:
Very nice rom！but auto rotate can't take effect
[Xperia Tablet Z Original Android Development] L.F.B.:
I want to test this rom very much...

But, I have a problem... I have lost my recovery! I cant imagine how! I just cant boot recovery anymore...

Im on LOS 15.1

Any fix for restore back my twrp recovery? Without the need of computer... ??
[Xperia Tablet Z Original Android Development] lm089:
Have you read other posts in this thread? There aren't too many yet, so it doesn't take too much time.

The only way I'm aware of to fix your situation is through fastboot/bootloader, and I don't think you have proper access to your phone's local storage from your bootloader (experts: please correct me if this is nonsense). So I don't believe there's a way to fix this without a computer. What you could try is to uninstall Magisk (in case you have it installed) through Magisk Manager; I don't know whether that really works, but you could give it a try:

There is an issue with the official LOS 15.1 versions for many Xperia devices (including our pollux_windy) in combination with Magisk versions 19 and higher; most probably that is your problem. You'll have to re-flash TWRP onto your device, it's a two-step process, you can find instructions here.

After that you can flash this ROM here. If you wish to return to the official LOS 15.1 make sure that you revert Magisk to V 18.1 (afaik that was the latest 18.x build), or quit using Magkisk and go for the LOS su tool. Or you go for the unofficial LOS 15.1 which doesn't have the Magisk incompatibility issue.

Allow me one final word: this ROM here is really nice but you have to be aware that most sensors currently are broken: no compass, no auto-rotation etc. (see a few posts back). The only sensors I found still working on my device were touchscreen and light sensor.

[Xperia Tablet Z Original Android Development] Komapatient:
Hi,

I installed the latest build and I am facing a problem with shutting the tablet down and rebooting into recovery.

Instead of doing either those things the tablet always reboots back to system.

It is a clean flash with no gapps or su/Magisk installed.

Is anybody else facing this problem?
[Xperia Tablet Z Original Android Development] fireflygwyn:
Thought it was just me. However repeated attempts finally got me into recovery. Might be a timing thing. Otherwise all is good for this version for us so far.
[Xperia Tablet Z Original Android Development] CaHbKaUp:
Yes, its known problem
[Xperia Tablet Z Original Android Development] lm089:
Cannot confirm: pollux_windy, clean flash, but with pico gapps and Magisk 19.3. Boot to recovery through extended shutdown menu working as ever

Otherwise still testing this build, but looks very good so far. Great job and many thanks all devs :good:
[Xperia Tablet Z Original Android Development] Komapatient:
I have a pollux.

Forgot to mention that.
[Xperia Tablet Z Original Android Development] lm089:
Done a bit of testing throughout the day today. Good news is that esp. the sensors are working again. Big thanks for that! :D :good:

Up to now I only found two minor flaws in the area of the navigation bar:

with unchanged settings at settings >> system >> keys >> buttons and order (in German "Schaltflächen und Anordnung") some extra buttons are displayed near the center of the nav bar, slightly right to the Home button, while they should appear outside the nav bar, or at least clearly to the right or left of the three main buttons. Example is the keyboard switcher appearing while the on-screen keyboard is displayed, another one are the "menu" dots of some legacy apps. Unfortunately I can't create a screenshot, so I tried to take photos of that.

Problem is that if I try to tap one of those extra buttons I in fact tap the Home button instead (there is a highlighted area appearing on-press showing that clearly).

One solution I found is chosing the option to make the nav bar left-bound (but... - see 2nd flaw below): then the extra items in the nav bar stay where they are but the default buttons are shifted to the left. But I really will have to get used to this, an off-centered nav bar is weird ;)

For the menu of my legacy app I also set a "long press Home button" action, works even better.

Mentioning the nav bar's layout: we have 4 options here: centered, compact, left bound, right-bound.

Centered of course is the default, compact apparently doesn't do anything (at least not visible to me), and right-left-bound are both doing the same: shifting all buttons to the left. As mentioned above: I don't really care, prefer to have my buttons centered; just found out while looking for a solution.

Update: while experimenting and describing all this I found yet another small one:

while in typing mode the "close the keyboard" button sometimes changes from the usual triangle into some kind of "dash"
[Xperia Tablet Z Original Android Development] mateotxiki:
Amazing.

All works perfect.

Thanks, thanks, thanks.

---------- Post added at 05:58 PM ---------- Previous post was at 05:53 PM ----------

Only a question.

When I install the ROM, the recovery twrp is replaced for the own recovery of Lineage.

Is posible recover twrp?

Sorry for my English...
[Xperia Tablet Z Original Android Development] jeromelec:
If you want twrp try to push vol + after power to access. If nope, you must flash twrp in fota with fastboot command. I think after you must reinstall the rom. And for root flash magisk 18.1 not later version. It works great and I don't know if lineage 16 has a patch for Xperia devices to flash magisk in the good partition.

---------- Post added at 10:33 PM ---------- Previous post was at 10:29 PM ----------

Works great. AMAZING, VERY FAST, LESS BUG THAN LINEAGE 15.1.

THANKS
[Xperia Tablet Z Original Android Development] L.F.B.:
Thank God, I got to flash back twrp on fastboot!

This Rom is amazing! For me is better than official 15.1!

Amazing kernel job!

Rom evaluation POLLUX

I spent quite some time CLEAN installing and testing the rom. After thanking for this very nice rom, I would like to present what problematic issues I have noticed. Some of them have been presented by others. First of all, when you install it, regardless on whether you have installed magisk, either old or 19.3, you loose twrp. Of course you can reinstall it in fota, following the directions. Second is that you cannot restart to any recovery, by using the extended restart menu. The only way to enter recovery is by using the power and volume up combination. Also, the Android setup wizard could not complete and was kept crashing. One thing though which made me go back to the stable rom I was using, was the fact that, after a while I could not shut down the tablet. Pushing the shutdown kept resulting to rebooting the tablet. I have pollux by the way.

If these things are fixed then the rom will be perfect...
[Xperia Tablet Z Original Android Development] lm089:
Won't help you much, but none of those issues apply to my *pollux_windy*. The only thing I found after ~2 weeks usage - apart from that navigation bar issue - is that the device occasionally crashes and reboots. Happened 2 or 3 times so far. I've always been too surprised or busy to go and get a Logcat, that's why I haven't reported it yet.
[Xperia Tablet Z Original Android Development] manicmarvin:
Same... But I don't get the reboots ?
[Xperia Tablet Z Original Android Development] CaHbKaUp:
First

Magisk issue when kernel didnt see twrp after installation was resolved in last 2 or 3 builds ago (magisk cant erase it because dont know about fota partition). In Lineage 16.0 we have no twrp in boot as was in previous versions and i will not continue to try make buildin twrp coz of 16.0 specifics, so vol - will boot lineage recovery, and vol + for twrp from fota.

Second

Its known bug and already fixed, fix will be included in upcoming september build.
[Xperia Tablet Z Original Android Development] L.F.B.:
OK this rom is great! I only have issues on Bt... Switching on or off... Sometimes the system freezes and reboot.

Other times wen my pads are paired fine... But Bt stop working and system reboots.

I know this is no big deal and our great dev [MENTION=7827892]CaHbKaUp[/MENTION] is aware on this...

Im just reporting for future improvments on this great rom! We are already blessed that this device is on Pie!???
[Xperia Tablet Z Original Android Development] Alec07007:
there is no recent apps button when making display size smaller
[Xperia Tablet Z Original Android Development] lineagefan123:
Very stable, with one exception

This is a great ROM and generally runs like a charm.

After ~1w of usage however my pollux windy (build from August 11) crashed 2 times in sequence, then the file system was broken. I had to reinstall.

I have it now running already since a couple of days again, so far this did not repeat.
[Xperia Tablet Z Original Android Development] lineagefan123:
The app Total Commander let's the system restart reliably and immediately.

I've been using it for years on former versions of lineage OS on the tablet, without any issues.
[Xperia Tablet Z Original Android Development] lm089:
Hmm - I'm having infrequent reboots, never pinned that to TC. My last reboot occurred while opening the Google Play Store app and wating for the starting page to populate. It may be that TC was running in the background then.

Quick question regarding the SDK: from what I understand this version here should use Android SDK V 27correct?

I'm asking because apparently Google play thinks that my tablet (POLLUX_WINDY) is running an older SDK (can tell which one, though). There's one beta test app I'd need to install but it isn't showing up in play store, and the developer says it requires SDK V 26 or higher. A 2nd case is some gaming app (https://play.google.com/store/apps/details?id=se.feomedia.quizkampen.de.premium): looking at its version in playstore from my tablet I'm offered a 3 year old version. Doing the same from my OnePlus 6 phone I'm always offered the most recent versions.

So I'm wondering whether my tablet probably is showing up at play store as an old Android version instead of Android which it really is.

Maybe one of you could just have a look at the linked app through their pollux_windy and let me know which app version they are seeing: the most recent versions are V 6.x, where my pollux_windy only sees V 2.x

And, if that's the case: is there something that can be done about it?

Thanks
[Xperia Tablet Z Original Android Development] enigmedark:
So far the tablet is almost 7 years old since its release (I bought it in pre-order), I think it is discontinued. But despite all that we can still have Android 9 in it and continue using it without problems.

I just want to say thank you to the developer of the rom for all his effort to allow us to continue using this great tablet.

Xperia Tablet Z My Xperia Tablet Z is 2gb Ram 32gb Rom LTE SO-03E docomo

hi Everyone, i Want to confirm if its possible to install this Rom in my (SGP321) Pollux 2gb Ram 32gb Rom NTT Docomo (SO-03E) on box but in about phone it shows details Below

Model Number: SGP321

Android Version: 5.1.1

Kernel Version: 3.4.0-perf-gbccb33a

Build Number: 10.7.A.0.222

Hope someone can clarify, im not sure but as far as i know Sony Xperia Tablet Z LTE SO-03E for Japan & Sony Xperia Tablet Z LTE SGP321 for Europe. if it shows Model no. SGP321 can i install Pollux lineage 15.1 or 16?

Thanks in advance
[Xperia Tablet Z Original Android Development] Rootk1t:
In brief: you can install SGP321 stock 5.1.1 firmware to SO-03E, but you can't install any custom ROM, because of the unlockable bootloader.

As far as i remember: Android 8.1 (API level 27), Android 9.0 (API level 28).

Is there a way to check version of the app in Gplay without app installation?
[Xperia Tablet Z Original Android Development] lm089:
Yep, LOS 16 = Android 9 and should be api level 28

For the quiz app I'm offered v 2.1.9, last updated 09.09.2015 if I use my tablet (screenshot included). Using my oneplus 6 I'm offered V 6.0.8, last updated 07.10.2019. Seomedia support doesn't have clue what's going on.

Rebooting issue

I have Sony Xperia Tablet Z Wi-Fi

with Android 8.1.0, LineageOS version: 15.1-20191017-NIGHTLY-pollux_windy

I installed the ROM via TWRP 3.3.1-0 with these steps

1- Wiped these contents: Dalvik, Cache, Data, System & Internal Storage

2- Installed ROM lineage-16.0-20190915-UNOFFICIAL-pollux_windy.zip saved on external SD Card

3- Wiped Delvik Cache

4- Installed Gapps ARM Pico

5- Rebooted into system

After waiting for the lineage blue curved line with circle moving tens of times the tablet Rebooted into TWRP recovery redid the same steps above then again rebooted into TWRP recovery

I did all steps above again without installing Gapps and again rebooted into TWRP recovery

I had to restore my Android 8.1.0 from backup till finding a solution for this issue.

Do you have any solution for this rebooting issue?
[Xperia Tablet Z Original Android Development] enigmedark:
Try with "Format Data" on TWRP to delete encryption. If that doesn't work:

Flash a stock rom with flashtool, flash TWRP like boot.img from fastboot with adb, reset, do a factory reset and install rom again.
[Xperia Tablet Z Original Android Development] mahair1970:
Thank you [MENTION=7098737]enigmedark[/MENTION] I will try your suggestion by deleting encryption as I realized TWRP booting process is very slow and I searched to find about this issue and found people relating it to the encryption.

I am not going to follow your other suggestion I'd rather stay on my Android 8 Oreo than going through the process of flashing stock ROM and factory reset as I already unlocked my bootloader and I may have issues with stock ROM.

Hopefully, deleting the encryption will resolve my issue.

I will keep you posted
[Xperia Tablet Z Original Android Development] mahair1970:
I did removed encryption via TWRP recovery by going to terminal and issuing the following command

recovery --wipe_data --set_filesystem_encryption=off

Which I found on https://android.stackexchange.com/questions/98228/removing-encryption-from-recovery

The tablet rebooted into Android 8 with the new setup process >> went through it >> tried to reboot into recovery but TWRP was gone >> reflashed it via fastboot >> rebooted into recovery >> installed the ROM & Gapps >> rebooted >> waited to finish the Lineage logo movement but it rebooted again into TWRP recovery.

Again rebooted into TWRP recovery >> ran format data >> wiped Dalvik, Cache, System, Data & Internal Storage >> installed ROM only again >> rebooted >> waited for Lineage logo but it rebooted into TWRP recovery again.

Why is this happening? I wonder
[Xperia Tablet Z Original Android Development] enigmedark:
How do you flash TWRP with fastboot? What commands?

I really recommend you flash stock rom with flashtool, you can do a backup of your actual rom before. The process don't lock your bootloader so you can restore your rom without problem. Also you can try with a flashable TWRP instead of fastboot.
