Hey I'm thinking about picking up this tablet for around $80 - $100 CAD. Can someone comment on performance? I've got a handful of tabs all mostly running LOS. Nexus 7, Nexus 9, a Tab Z, and a Shield K1. I'm wondering if the 3GB ram makes a noticeable difference?

The only one I've really been disappointed in is the Shield. The 9 and the Tab Z I'm using as external displays. The 7s performance cant cut it as a replacement for my Shield.

I guess my question is will it perform as well as an iPad Mini 2 or better?

Couldn't upgrade to the September update using the standard recovery. I flashed pbrp and then the update went fine
[Xperia Z3 Tablet Compact Original Android Developm] tommes_d:
No problems here with SGP621 and OF-recovery. Works fine since first to last release. Recommended.

Perhaps my battery has deteriorated or the new firmware incorrectly sees its level. My device now turns off after 4-5 hours
[Xperia Z3 Tablet Compact Original Android Developm] Pfrinz:
No problems with the battery, more of the opposite. I am really satisfied with this old device!

BUT: sound problems with the speakers are back again. Volume goes down after a short time, sometimes its fluctuating and often it just stays down. Not totally, but quite anoying :)

No probs when headphones are used, BT or cable doesnt matter.

Whats the solution to this, do you guys kno, or maybe @evil-god has some advice?

Thanks!
[Xperia Z3 Tablet Compact Original Android Developm] mchaals:
with the september update I had strange feelings about the battery percentage display. I felt it shows incorrect values, but the battery draining was okay for me.

Just installed the october version, I'll see how it works.
[Xperia Z3 Tablet Compact Original Android Developm] mchaals:
maybe it's late, but here is my opinion:

the tablet works well for me. I'm using it mostly for streaming Netflix, HBO, Disney and Amazon. It is more than enough for that. Also basic games work okay, but I'm not a gamer on tablet. Browsing, twitch, youtube, all the basic stuffs are okay without any problem.
[Xperia Z3 Tablet Compact Original Android Developm] sydenis2:
I also think there is something wrong with the indicator. The device may turn off when it shows 60% charge. The device cannot be turned on again. If you plug the charger into a switched-off device, then you can see on the black screen that there is already half a charge.

Hi everyone!

Today the firmware was installed with the 20221014 patch.

And...

It is alive!

Radio FM works!

It is amazing! It's magical!

@evil-god Thank you awesome!
[Xperia Z3 Tablet Compact Original Android Developm] Nightsax:
From the reviews of this tablet I've read, the screen is not very well calibrated, and usually has a blue tint.

To correct this:

-Go to Settings-> Screen-> LiveDisplay-> Color calibration. Here, reduce the Blue color to your preference (I've set mine to 88%).

To get to this number I calibrated this manually, using a recommended setting I found on a Android 6 review of the tablet to correct the blue tint.

Then I compared visually using photos, and adjusted with two tablets side by side (Android 6 setting and Lineage 18.1).

Feel free to correct this the way you want, but overall my setting should look better regarding screen color of the tablet.

My 2 cents contribution to this great ROM I am so pleased about! Cheers

update my z3tc from 20211114 to 20221014, as result - bluetooth headphones stop working properly, but music still plays

trying clear instal of 20221014 - same result: music player works fine, but can't make voice calls.

does anyone has similar problem?
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
I have no problems with the speakers or the battery indicator. The Rom is still great. I even had the battery changed some weeks ago, because there is not really a better competitor in this tablet screen size and that there is still a developer that keeps this great tablet alive. Thanks again to @evil-god for his great work. (y)(y)(y)

My z3tc (SGP 612) 32GB WiFi without LTE is not recognized during installation via twrp. The process is aborted with error 1. Is there a possibility to adapt LOS 18.1 so that I can use a relatively current ROM on the still well-preserved tablet?

greetings
[Xperia Z3 Tablet Compact Original Android Developm] kos25k:
@wirdSchoon i think someone did it.You can search the thread though.Guys my SGP611 feels laggy many times (not all) Sometimes app can take even 10 seconds to load.Does this happen to you also?If no,maybe my hardware went corroded or something..Also is there any hope of los 19.1 or 20?
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
I have no performance issues on my SGP611. Still running well. What LineageOS 19.1 or 20 concerns, I read that they made changes in how networking works in LineageOS 19.1, in order that it works more efficient. Unfortunately a lot of older Linux kernerls are now not longer supported, because of this changes. And I think the kernel version of this great tablet is to old. :cry:
[Xperia Z3 Tablet Compact Original Android Developm] exault:
Tried latest image on my SGP612 (0221119) but after flashing it with TWRP it no longer boots (dead boot only one vibration on power up).

Only way to recover is using Emma.

Also using PBRP as boot / recovery also makes it unable to boot (same as after Lineage flash)

Could it be that something is wrong concerning the boot for this image ?

Some help needed here to get this installed.

Tried Lineage 15.1 image and it boot without any issues after TWRP flash.

it seems i cant enter recovery after flashing the lastest rom (11/2022) . I install recovery from fastboot, everything seems ok. But cant enter recovery after reboot. I tried both orange and Pitchblack.

Anyone knows why? Any solution?

Latest update for Wifi version did not work. Says its not made for Wifi tablet in recovery...

Looks like LTE version of the file was uploaded to both links.
[Xperia Z3 Tablet Compact Original Android Developm] :
First oft all , hello and thank you for making lineageos working on this fairly old device. I am using 611 wifi only. After fiddling around a few hours i made it work with flashing lineage recovery. Right now i am on the october update. I just wanted to update to the New december update but recovery stated the update is for the z3tc Version only as member corb06 says above. Also i have to ask wether i need to wipe and delete all data ( seems like only factory reset is possible in lineageos recovery) before updating every New upcoming update or jjust doing a dirty flash. ??

Thank you in advance
[Xperia Z3 Tablet Compact Original Android Developm] Levistras:
Rom works great, has breathed new life into my Z3TC.

One thing I haven't been able to get working is using the SD Card as Adoptable Storage. Sometimes it formats and sets up OK, but after using it for a day or so the SD card shows up as Corrupted and needs a new format.

Other times it just fails at formatting and throws up an error message.

Anybody have any luck with getting to this work? I've tried two different SD Cards and behavior is the same.

Tried to update to latest SGP611 update 20221216 and failed, tablet stuck in flashmode :(

I downloaded Emma, reinstall stock firmware with it, reinstalled recovery and did every step from post #1. After flashing latest ROM, tablet is stuck in flashmode again...

Really lost now, I am going to try to find the previous update somewhere.

Edit: I confirm the latest version (20221216) is non-functional on SGP611.

I've just reinstalled version 20221119 (using OF-recovery), did every step from post #67 (except step 3 where I had to use "fastboot flash:raw boot boot.img") + all wipes recommended in post #1 and finally, after spending hours on it , my tablet is working again.

Seems like it's the same file for SGP621 on both links from post #1.

Note to myself: be careful in the future and think twice before updating...

Magisk 25.2 is working.

Mine is SGP621, just use magisk manager app 25.2 to patch boot.img extracted from lineage-18.1-20221216-UNOFFICIAL-z3tc.zip, check "Patch vbmeta in boot image" then flash patched boot image in fastboot mode.

If it's not working for you, just flash original boot.img and patched magisk.zip v22.1 to rollback.

Just FYI
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
Just flashing the ROM.zip via recovery and the Magisk 25.2 afterwards the same way.

It is working here.

Up-to-date LineageOS for microg builds are now available on AndroidFileHost

Note that these builds are still untested - I don't have a device with an unlocked bootloader to test on.

Details about unofficial and custom builds available in my project Wiki

Feedback welcome here or, in case of bugs, in the project issue tracker
[Xperia Z3 Tablet Compact Original Android Developm] Levistras:
This is the degoogled stuff right? Can I still install opengapps?
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
No. If you want Gapps then use @evil-god's normal builds. LineageOS for microg is for users who don't want or need any of Google's apps or APIs. It has replacements which allow apps that use Google's APIs to function correctly (mostly) without them.

Installing openGapps will have strange consequences and won't end well :)

Thank you, it's working now. Since the release of this rom there has been every month regularly updates, without any issues. So it's the first problem with an update that I can rember. So don't worry. Like I said before, I'm just happy that this great tablet is still maintained. Thank you :)(y)
[Xperia Z3 Tablet Compact Original Android Developm] tool8:
First of all, thanks evil-god and petefoth for your work! It is amazing to see this tablet (SGP621) coming back to life. I ended up using the microg-build as I am already using /e/OS on my daily driver (XA2).

I wanted to share my experiences here because getting recovery to work was not easy.

OF or pbrp didn't work, and it took me a while to figure out that the reason was that I was still on Android 5. Because the bootloader was unlocked I could only use EMMA to reflash, and that provides only Android 5. Xperia Companion has the latest Stock-ROM but won't flash an unlocked device. I could not find any recovery working with Android 5 so I had to relock the tablet, which I could only achieve using Flashtool.

Everything is working now, including 5Ghz Wifi.
[Xperia Z3 Tablet Compact Original Android Developm] evil-god:
why are you not use fastboot for flashing recovery? just do "fastboot flash recovery yourimagename.img" in fastboot mode and you are good.
[Xperia Z3 Tablet Compact Original Android Developm] tool8:
Oops, sorry it wasn't clear. I did that with OF and pbrb but after that the device would not start in recovery mode, just black screen. In fact it did not boot to system either any more and I had to unbrick it using EMMA, which will only flash an old Lollipop ROM. Once I managed to put Marshmallow on the tablet it worked just as you describe it.
[Xperia Z3 Tablet Compact Original Android Developm] plateav:
me da error 1
[Xperia Z3 Tablet Compact Original Android Developm] the.fall:
Thanks for this ROM! I just switched from stock Marshmallow since a lot of apps were not available anymore on the Playstore with it. It's nice to see this tablet revived again.

I just have one question: GPS doesn't seem to work with my SGP611 and latest LineageOS 18.1 build (December 2022), I don't get a location fix in any app. Is this a known issue?
[Xperia Z3 Tablet Compact Original Android Developm] contravener:
Anyone?

I can enter fastboot with volume up + usb plug into PC

I run fastboot with command "fastboot flash recovery *(pb or orange or lineage recovery, i tried all of them).img"

Command "fastboot devices" finds my device.

Flash is successful. I execute command "fastboot reboot". I unplug usb.

I turn off z3tc.

Then, i hit power button + volume down and z3tc doesn't enter recovery. It justs boots into system. Am i doing something wrong?

No led turns on during power button press
[Xperia Z3 Tablet Compact Original Android Developm] the.fall:
Entering recovery works for me like that (with flashed OF-Recovery in recovery partition):

Turn device off.

Press ONLY power button until device turns on, then let go of it.

The Sony Xperia logo appears. Now at some point, the LED should turn green. As soon as this happens press VOL DOWN shortly, do not keep it pressed!

As soon as you let go of VOL DOWN, the green LED should turn blue for a short time and OF Recovery loads afterwards.
[Xperia Z3 Tablet Compact Original Android Developm] contravener:
unfortunately, in my case no led is turned on during power on procedure. It just enters system.

It did, initially. I remember it did.

But at some point, after some flashes and reflashes of roms / recoveries, led stopped appearing during power on.

Led is working, it illuminates in system for notifications etc.

What is the difference of : "fastboot flash recovery ..." and "fastboot flash FOTAKernel ..." commands? I have tried both with no success

[Xperia Z3 Tablet Compact Original Android Developm] daKump:
Had the same problem (device did not boot into recovery mode and green LED did not light up at start) and semi solved it that way:

Extract LineageOS Build (in my case lineage-18.1-20230119-UNOFFICIAL-z3tcw.zip)

Change directory and flash the boot.img

cd lineage-18.1-20230119-UNOFFICIAL-z3tcwfastboot

flash boot boot.img

Unplug and start the device. Now the green LED showed up again and with a press of Vol- it turned into blue and launched me into Recovery Mode (pbrp in my case), from there i flashed the ROM from SD

(Install of the MindTheGapps Rom failed, but Roms runs nicley.)

However, now again i am not able to get into Recovery Mode again, a sort of LineageOS Bootloader appears and the option to boot into pb recovery mode does not exist :unsure:

Might need to Flash the pb recovery again..

Does the tablet run any smoother with this ROM compared to the latest original one, or the Android 11 that it's based on is heavier for older devices?

Should I flash it? I don't experience any problems other that the device after all those years was got slow.

Yes I know. It worked out for me. I used Opengapps before, but the stopped at Android 10. Oh, I saw now that Android 11 is also available with Opengapps. So if you want to go safe take this one with platform ARM. Here is a link : https://opengapps.org/
[Xperia Z3 Tablet Compact Original Android Developm] kos25k:
Thanks.But this package seems outdated (15 Feb 2022) I will try nikgapps.My tablet lags very much in point i can't use it.Also when i flash pitchblack recovery from twrp (scorpion 3.0.2) it asks me to install as boot or system.But when i flash as boot,it desapears after next boot.Can i choose install to system?
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
Yes, I think it's not working with TWRP. I also using the pitchblack recovery. But honestly I'm not sure if you can flash it to system. I flashed it with adb.
[Xperia Z3 Tablet Compact Original Android Developm] kos25k:
And it stays permanent?Which command u used?You mean u straighly installed pitchblack from cmd or twrp and then pitcblack?
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
Yes ofc, it's the recovery. You have to install it with a computer with adb.

fastboot flash FOTAKernel should work
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
Yes it should. There many commands to flash a recovery. But you should search a bit in the web how to do it, if you are not so familiar with it....

I'm having problems booting my Z3TC WiFi SGP611 to recovery. Flashing recovery using `fastboot flash FOTAKernel pbrp_9.0_z3tcw.img` seems to work, but when I try to reboot to recovery the device boots into stock ROM. I have tried

fastboot reboot recovery

adb reboot recovery

Pressing Volume down + Power buttons

Am I missing something basic?

EDIT:

I also tried flashing with `fastboot flash recovery...` rather than `fastboot flash FOTAKernel..`, but same result :(
[Xperia Z3 Tablet Compact Original Android Developm] skt830:
First of all thanks to OP and all the contributors. I got this working after a several tries and very happy with it overall. I have a couple of issues so thanks in advance to anyone who can point me to the right direction...

First issue is display related, Chrome was acting up for some reason (black line on top and wasn't responding) but after several wipes and factory resets that seems to be fixed. The other display issue I am having at the moment is with Here We Go app which causes constant flickering.

Second issue is with Magisk, even though I followed the instructions (renaming modded apk to zip and installing it that way and I see the icon , when I click on it it says it needs to download something but fails...

Thank you very much again.

Edit: 5ghz not working for me also, tablet was bought from Amazon Germany Sgp621 model.

[Xperia Z3 Tablet Compact Original Android Developm] Jems_:
put the rom on sd card, fastboot flash FOTAKernel pbrp_9.0_z3tcw.img . boot to prbp install the rom then reboot. your system should be Lineage and the recovery should be TWRP.
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
OK I'm being really dense: how do i boot to prbw?

I've tried

fastboot reboot FOTAKernel

fastboot reboot recovery

fastboot boot FOTAKernel

None of them work :(

have you look this thread ? https://xdaforums.com/t/xperia-z3-tablet-compact-cant-boot-into-recovery.3825793/
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
Yes. I've read the whole thread and now I am more confused. I have unlocked the bootloader successfully, I don;t want or need root. And I don't understand why that thread talks about flashing to the `boot` partition, when on other Sony devices (including Z3 and Z3 Compact) I normally flash the recovery image to the `recovery` partition, and your instructions use `FOTAKernel`. But I can leave finding out about all that until later :)

All I want at the moment is to know how to "boot pbrp"

I'm following your instructions, from earlier

The bootloader is unlocked

`fastboot flash...` command worked,

$ fastboot flash FOTAKernel pbrp_9.0_z3tcw.img
Sending 'FOTAKernel' (14868 KB) OKAY [ 0.575s]
Writing 'FOTAKernel' OKAY [ 0.987s]
Finished. Total time: 1.575s

But none of the usual ways I know of booting to recovery work: they all end with the Stock ROM running
[Xperia Z3 Tablet Compact Original Android Developm] M1chiel:
It has been a while since I worked with this tablet, but if I remember correctly the fastboot commands for rebooting into recovery don't work for this device. The button combination (power and either vol - or +) works but timing of releasing the buttons is key to boot into recovery. If you release too early or too late you boot into system instead. Also the original recovery may be restored if you reboot into system, so you must reflash the custom recovery first after you failed to boot into recovery.
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
Thanks. I'll give that some more tries.

But now - after experimenting wth `fastboot flash...` and `fastboot boot..` commands, the device won;y boot into stock :( IT displays the blue 'wavy line' startup animation indefinitely :(

I think I need to reflash the stock firmware, if I can find it anywhere
