Hi there,

I have been using the rom and it works nicely but there are a few things that is strange, well to me that is.

Some info on my device and rom.

Device is the WiFi version SGP611.

Using the latest lineage-18.1-20240321-microG-UNOFFICIAL-z3tcw.zip rom.

I flashed this with OpenGApps pico and the Play Store crashes every time even on reboots, I believe it has to do with its update as uninstalling the updates avoids this but I don't want to be doing that every time I want to access it. Tried both root and unrooted, same problem. I tried the version before microG and it works but for some reason drains the battery, barely half a day compared to microG one and I can get a full day or more. So I don't know if the microG version was not supposed to work with OpenGApps or not, I was wondering if anyone have faced this issue. Aurora Store is my alternative for now but I would like Play Store working, if this is not the case with the microG rom then please advise.

Also I cannot seem to cast. I am aware of the drop of Miracast on Pie but the Lineage OS 18.1 has that option. What it doesn't have which seems to be on the web is the 3 dots to enable wireless display which can be found in the Settings>Connected Devices>Connection Preferences>Cast. So I am stumped on this, is there a way to restore this option?

Thanks for your time and look forward to hear back.

Cheers
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
microG and GApps cannot co-exist. microG provides replacements for the Google APIs provided by GApps. Having both installed will cause many problems.

If you want to use Play Store, then you cannot use the ROM with microG

If you want to use the microG ROM, then you can't use Play Store
[Xperia Z3 Tablet Compact Original Android Developm] dude777:
Thanks for clarifying that, I will stick with microG with Aurora Store then, as it's working as intended.

What about the Cast? is that something that is not supported?
[Xperia Z3 Tablet Compact Original Android Developm] petefoth:
Sorry, I don't know about that. The microG code doesn't remove or change that functionality, so maybe it's just not supported for this ROM on this device. Maybe someone else knows more
[Xperia Z3 Tablet Compact Original Android Developm] dude777:
All good thanks for your response I'll find some other way, cheers
[Xperia Z3 Tablet Compact Original Android Developm] Suprachilla:
I would like to know how the performance of this ROM is.

I am still running on stock. It is pretty laggy.

Does this or any other ROM improve performance at all, or is the device just too old to feel snappy?
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
It runs pretty smoothly - give it a try!
[Xperia Z3 Tablet Compact Original Android Developm] ghaeh:
Did I hard brick?

After a few years, I decided to update to the last wifi release and trim the Gapps, did a system reset, entered PBRC, cleared cache, Dalvik etc but the USB port wasn't connecting to ADB - should have tried other ports as the drivers are still installed.

I left it in PBRC for an hour or so while fiddling with driver stuff. When I got back to the tablet it was off and no combinations of buttons or plugging to charger or USB succeed in so much as the blink of a light.

About the only thing I can think of is opening the case and disconnecting the battery and plugging it back in.
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
you could try out Orange Fox Recovery instead, to see/tell, if you hardbricked or not
[Xperia Z3 Tablet Compact Original Android Developm] ghaeh:
That presupposes I could get into fastboot.
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
if getting into fastboot is the problem, you could try different system and/or usb ports / fastboot drivers.. if nothing works, then you bricked indeed. but i think this is highly improbable.
[Xperia Z3 Tablet Compact Original Android Developm] ghaeh:
PBRC Hard Loop

The tablet was pitch black and unresponsive in my saga of trying several USB ports and verifying drivers until a red led came on whenever I plugged it to a USB or power. Pressing the power button showed it was charging the depleted battery. After charging the tablet now boots into LineageOS(y)

My suspicion is that PBRC went into a hard loop rendering the tablet unresponsive until the battery was depleted. I don't remember if I tried anything on the blank screen. Anyway the tablet did a really good imitation of a hard bricked power off state.
[Xperia Z3 Tablet Compact Original Android Developm] faldo:
I couldn't get GPS to be stable either so i moved to FLOKO and it works great now

Your warranty is now void. I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM...

[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
😬 I'm sorry. I think it has something to do with this recovery. Because it's not a TWRP recovery, it is a orange fox recovery.
[Xperia Z3 Tablet Compact Original Android Developm] tommes_d:
I had Windy in the past and flashed TWRP / CM 14.1 to FOTA: https://xdaforums.com/t/rom-unlocke...eageos-beta-njh47d-for-sgp611-sgp621.3532370/

Maybe OF does not interact with SGP611 as TWRP - I don´t know. Anyone of the users who flashed 18.1 to Windy could describe exactly what they have done?
[Xperia Z3 Tablet Compact Original Android Developm] meksis:
Installed the firmware on sgp611, everything started fine. I decided to try to install magisk. Tried different versions and all without success unfortunately. (((If anyone finds a working method to get root rights on this beautiful firmware, please share. Thanks. I had to roll back to Floko Rom ((((
[Xperia Z3 Tablet Compact Original Android Developm] madxxcow:
As for now there is no root method, see #1
[Xperia Z3 Tablet Compact Original Android Developm] madxxcow:
I had a similar situation some years ago, coming from a quite old firmware. In order to make a more recent recovery working I had to first go through a bootloader update. This is done by flashing the latest official firmware 23.5.A.1.291. Then you flash recovery, then lineageos 18.1
[Xperia Z3 Tablet Compact Original Android Developm] zuiffon:
In fact to boot to recovery, I must power on with "the standard method to power on the tablet" without any volume button and when the led become blue quickly press volume down alone.
[Xperia Z3 Tablet Compact Original Android Developm] mind.inc:
So, for all the SGP611 users that are still struggling to install this, I did the following and got it working:

1) flashed latest stock to start fresh with flashtool from androxyde version 0.9.18.6 (only version working for me)

2) extracted boot.img from the rom zip itself

3) flashed the following via fastboot:

fastboot flash recovery OF-recovery.img

fastboot flash FOTAKernel OF-recovery.img

fastboot flash boot boot.img

4) unplug and restart device. When you see the LED starting to show up, just press and hold VOL down.

5) flash rom and gapps (optional)

6) reboot and that's it.

Thanks to @evil-god and @joschi1979 and all other participants for providing informations.

Hope that this will help others to get their SGP611 running LOS18.1 too.
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
Just to be on the safe side: From which rom zip did you extract the boot image? Many thanks for this detailed instruction!
[Xperia Z3 Tablet Compact Original Android Developm] mind.inc:
Out of the latest zip provided by @joschi1979: rom
[Xperia Z3 Tablet Compact Original Android Developm] zuiffon:
If you have the message "error - the bundle does not match the connected device" when you try to flash latest stock with Flashtool you can use "Emma" from Sony.
[Xperia Z3 Tablet Compact Original Android Developm] corb06:
I have SPG6111 with Floko Rom at the moment using recovery TWRP_scorpion_windy_3.3.0-0_201905.img.

Can I just boot into recovery and flash the this rom?
[Xperia Z3 Tablet Compact Original Android Developm] mind.inc:
Guess you just need to try. I've been on TWRP 3.2.1.3 and got some weird errors. No errors with OF recovery though.
[Xperia Z3 Tablet Compact Original Android Developm] tommes_d:
1 month of daily usage and I faced 2 problems with LOS 18.1.:

- navigation bar sometimes disappears when starting an app. I got fullscreen mode with no chance getting back to homescreen or switching to another app. Only restart helps. This happened 5-6 times.

- Yesterday suddenly the WiFi-Icon in the status bar disappeared. Tried to switch WiFi off an on again, but no reaction when clicking on the quick settings icon. Even the network settings section in system settings could not be opened.

Tried to restart the device, no reaction. Had to hard reset it.
[Xperia Z3 Tablet Compact Original Android Developm] meksis:
Unfortunately, it won't work. I already tried it, the error appears. The firmware was installed only on Recovery, which is in the topic header.
[Xperia Z3 Tablet Compact Original Android Developm] corb06:
Yeah! I went ahead and tried as well, lots of e: fstab errors. Barley managed to flash back the Floko Rom, kept getting errors there also for a while. Had to mount and dismount the system and data many times.
[Xperia Z3 Tablet Compact Original Android Developm] suuperboom:
I just got this running on my SGP611. Thanks @evil-god & @joschi1979 !

Couple of issues -

1) disappearing navbar sometimes as mentioned in #73

2) audio in youtube particularly is going funky, sometimes really loud for a few secs then drops back to normal volume. But in either case audio does not sound as "smooth" as on stock MM, sounds very harsh/sharp at louder volumes. I tried adjusting in AudioFX app, but whatever is changed in there doesn't really seem to have an effect?

Without root/magisk no way of getting Viper4Android or Xperia Audio Enhancement onto the tablet.

Anyone having same issues or any suggestions about the audio issue?

Was trying to get lineage 15 on it, but cannot find the TWRP required for lineage 15 anywhere.

If anyone has TWRP 3.2.1 / recovery for lineage 15 for SGP611 - Please PM me! or post it up please!!! @evil-god mabye?
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
I followed #67 and got it also running on my SGP611 - many thanks to all of you!

When flashing the boot image, I got 'fastboot: error: Couldn't parse partition size '0x'' but could easily fix this with 'fastboot flash:raw boot boot.img'. Thereafter, everything went smoothly. Up to now only one issue: The camera seems to work, but after pressing the shutter button, the camera freezes and does not store the image to the disk. I checked the permissions of the app, but they were OK. Any ideas how to resolve this?

@suuperboom: Lineage 15 can be installed with the official TWRP twrp-3.0.2-0-scorpion_windy following this thread - at least this worked for me.
[Xperia Z3 Tablet Compact Original Android Developm] suuperboom:
@flouli - how did you get the official TWRP to boot? I couldn't get it working (flash to recovery and fota, but it hangs after pushing vol down and LED changing color). I thought it needed higher than 3.0.2, but if it works with that I'll gonna give it a shot.

Camera is completely stuffed for me in 18 - not a big deal to me, but just for your reference. perhaps its generally buggy. it doesn't focus, and pushing button does nothing. Button is also half off the screen
[Xperia Z3 Tablet Compact Original Android Developm] roey787:
SGP611: My device booted to recovery, but the screen would not turn on. I used this Guide to install @joschi1979: rom with the help of TWRP recovery:

flashed the latest stock to start fresh with the flashtool from Sony (23.5.A.1.291)

adb reboot bootloader

fastboot devices -> device should be listed

fastboot reboot bootloader (optional?)

fastboot flash recovery twrp.img (I used 2.8.7. 3.0.2 should be tested. This step might be optional)

fastboot boot twrp.img (2.8.7)

<phone will reboot, the screen will be black>

<wait to Windows new device sound>

adb devices -> device should be listed

Type: adb shell

twrp wipe cache

twrp wipe dalvik

twrp wipe system (<- I got an error on this on)

twrp wipe data <- NOW YOUR DATA WILL BE REMOVED, SO MAKE A BACKUP BEFORE!

twrp sideload

adb sideload <location_of_your_ROM.zip>, e.g. adb sideload C:\Havoc.zip

When the installation is completed you will see "Total xfer X.XXx".

fastboot reboot > LineageOS should start up.
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
Well, that was a little longer ago. When I remember correctly, I came from stock (23.5.A.1.291) and had to additionally flash a modified boot.img - the solution should be somewhere in this older thread on lineage 15. Good luck with this!
[Xperia Z3 Tablet Compact Original Android Developm] brickedmytablet:
Man, I am in the same situation. My LED flashes grend-red-green. How did you get out of this? Flashtool (Androxyde) and Emma do not recognize the device unfortunately. Any ideas?
[Xperia Z3 Tablet Compact Original Android Developm] brickedmytablet:
Hey Max, I extracted the boot.img from the rom zip but the Tablet ist not recognized anywhere. Any idea how to make it flashable again?
[Xperia Z3 Tablet Compact Original Android Developm] brickedmytablet:
I made it work somehow. So here is what I did: I let the tablet battery go down as far as I could. Then I restarted the device and pressed the volume up button a lot of times in quick succession. This led to the start of twrp. I flashed the recovery from #2 to the /boot partition and restarted. In the official lineage-os recovery used factory reset to delete everything but the internal storage, then I reapllied the system-zip from #2 by going: apply update / local Storage / SDcard. After rebooting the system went through the green-red-green lights, but then stared normally.
[Xperia Z3 Tablet Compact Original Android Developm] Max8719:
First of all thank you to evil-good for building and sharing this rom. Also thank you to joschi1979 for making a build for SGP611 users.

I have tested the SGP611 build now for several days. Overall performance is very good and stable. Most things are working very well. (y)

But I also found some minor issues:

Speakers sound volume is a bit weird. Like mentioned in an other post before the volume sometimes gets automatic louder or lower, when watching a video.

Automatic brightness is not working very well. ( I think this is a general problem in custom roms for this device.)

Camera is not working. The app is starting but it is not possible to take a photo or shot a video. The app is generally very buggy.

Google maps app is crashing after a few seconds.
[Xperia Z3 Tablet Compact Original Android Developm] zuiffon:
Thanks for this ROM !

Most things works very well.

For the moment the only problem I find is that camera doesn't take photo with any application in photo mode. In video mode it works.

There's also the same problem than old lineage with instagram story some pixels are out of the screen in the bottom because it makes a black bar on top.
[Xperia Z3 Tablet Compact Original Android Developm] suuperboom:
@flouli - thanks I got it working. I did it the same way as for this 18.1 ROM. flash boot img then recovery img. Thanks dude!
[Xperia Z3 Tablet Compact Original Android Developm] koogas:
Hey guys, nice work on keeping this device up to date!

Is it possible to upgrade from the unofficial 15.1 LineageOS build to this version without major hassle (wiping everything, etc)?

Thanks!

Any ideas, how to solve it?
[Xperia Z3 Tablet Compact Original Android Developm] madxxcow:
You must do it through recovery.

I did as said in first post : unzip this modded apk and rename apk to zip, then flash via recovery
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Installed it. But if I try to start, there is still packet parsing error.

Update:

AAAAARGH!

Now even the recovery is not accessible (reboots into system), and a rollback to stock rom I cannot do. No Fastboot mode (Win 10 doesn't accept the drivers), ELSA and Flashtool don't want the tablet... f*ck.

This evening I will install all the stuff to a virtual Win 7 and hope, It hasn't this issues.
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Now I´m back to factory stock, with unlocked bootloader thanks EMMA.

But now I have still following problem: no root and no recovery mode. No way to do anything.

Rooting in flashtool doesn´t work, even not in Windows 7. If I use your method with fastboot flash FOTAKernel OF-recovery.img, there is no recovery.

Any hints for an old man?
[Xperia Z3 Tablet Compact Original Android Developm] madxxcow:
Have a look at post #67, FOTAKernel flash should be enough but this method worth a try.

Alternatively, instead of flashing recovery you may try to boot it without flashing, fastboot boot OF-recovery.img
[Xperia Z3 Tablet Compact Original Android Developm] madxxcow:
****, double posting, sorry
[Xperia Z3 Tablet Compact Original Android Developm] tommes_d:
Same problems in build 2021.05.08 as in prior version as described in #76:

- sometimes navbar disappears

- SGP621 loses wifi and after this system freeze (hardreset necessary)
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Still no recovery and root. Recovery seems to be installed, but nothing at screen visible. Strange.

Anyone a prerooted SGP611 6.0.1 ftf file with recovery for me? Or a way to flash a prerooted system in fastboot mode?
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Question: as long I tried it with 6.0.1 boot img and OF-Recovery it didn't work. What happens if I use for the procedere the boot image from Lineageos 18.1 and OF-Recovery; will it brick the tablet?
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
No, exactly this will do the job - see #67 + #69. I flashed it this way and it is now running stable for more than two weeks.

Once again many thanks to @evil-god & @joschi1979!

@joschi1979: Is there any chance that the camera issue canbe fixed?
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
I will try this way today.
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Worked! If the minor bugs (camera and sound) will be fixed, it could be a great tablet again! ;)
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Update

bugs:

- camera not working in foto mode (Video in skype works)

- google maps crashes

- Skype "lost" all contacts after reboot

- sound loud and scratchy sometimes
[Xperia Z3 Tablet Compact Original Android Developm] dagolard:
Yesterday tested a little bit. But probably I will go back to 15.1 for a while, until the 18.1 is more stable. Not at all a good work, and thanks to all developers to keep the tablet alive!

Ah, and for those who has a lack of battery: calibrate the battery after flash! This is VERY useful! I use this one (root, ad-free).

NoAd Battery Calibrator [ROOT] - Apps on Google Play

Calibrating your battery after flashing a new ROM may increase your battery life

[Xperia Z3 Tablet Compact Original Android Developm] Kojitosan:
Hi, I managed ton install the zip file thanks to Twrp. Everything seems to work perfectly except for the camera and the GPS which was expected. This version seems very fast and efficient, but when I tryed to scan the system with Avast and AVG antivirus, both apps are detecting 2 malwares build in the system. Is this a false alarm or did any of you experienced the same issue ?

For information, Kapersky and Bit Defender doesn't detect anything.

What are your feedbacks on that point ?
[Xperia Z3 Tablet Compact Original Android Developm] flouli:
I can not confirm problems with GPS (#100) and Google Maps (#98) - for me both work perfectly on SGP611. Also Magisk can be updated to the current version (23) via the workaround described by @evil-god. The only problem is the camera, which is not a major issue but would be nice to work.
[Xperia Z3 Tablet Compact Original Android Developm] evil-god:
please provide logs, on SPG621(LTE) everything is working, the result of your avast scan could be funny/nice, these apps a build for stock roms, not for custom roms ;-) and most of the time harmful. android !=windows
[Xperia Z3 Tablet Compact Original Android Developm] agneva:
Hi, I installed it today and was very happy. I only have one small problem, when playing music or audio books the volume sometimes goes very low. I've tried all sorts of things, different media players - but I can't find the cause.
[Xperia Z3 Tablet Compact Original Android Developm] Kat-CeDe:
Hi,

thank you very much for you effort for such an old tablet.

Is any camera on your tablet working? If yes which? I also have the LTE version and no luck with camera not even with movies like some mentioned here.

[Xperia Z3 Tablet Compact Original Android Developm] tommes_d:
Stock camera does not work for me too - SGP621.
[Xperia Z3 Tablet Compact Original Android Developm] SageDroid:
I installed lineage-18.1-20210504-UNOFFICIAL-z3tc on my SGP611.

Thanks first of all to your great work!

My first impression is that the ROM runs stable and smoothly.

So far I have found the following bugs:

- Camera cannot take pictures (three camera app tested, log with stock app here)

- Wireless debugging does not work for me, although it displays "Successfully paired". But it could also be that I am doing something wrong.

- The biggest problem is the audio output. The device randomly goes from normal volume to very loud and then back to quiet. It's not hard to replicate, for me it's constant with every song. I can't find anything in the log that seems helpful unfortunately.
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
Can we expect support for Magisk rooting on SGP621 soon?
[Xperia Z3 Tablet Compact Original Android Developm] mind.inc:
Read Post #1, it's already there.
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
Oh, thank you very much for the hint! :)
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
edit: question solved
[Xperia Z3 Tablet Compact Original Android Developm] Whumpscut:
Have the same error, could you please share, how you solved it?
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
So the question was about the not working install of the Magisk Manager after flashing the modded zip.

I just uninstalled the magisk icon and then went back to recovery and flashed the standard magisk v23, and it worked out.
[Xperia Z3 Tablet Compact Original Android Developm] Ermann123:
But I noticed, that some apps, which require root, do not manage to activate the magisk popup request for granting root priviliges.. do not know, if it is because of magisk or because of the app.
[Xperia Z3 Tablet Compact Original Android Developm] Dark001:
So, any ideas how to unlock 5Ghz WiFi for all regions?
