The reason why I recommend this is because there is new and fixed firmware (for the modem for example) in those stock FTFs. As far as I've tested it, the new loader is not required but recommended (Always bugfixes there). Also AFAIK, there is no modified bootloader available for the Z3TC (The ones seperating recovery from the FOTAKernel partition are only available for some lower end devices). And last but not least, to my knowledge there is no FTF only containing the bootloader.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Many thanks.

I am using the tablet quite a bit for speaker based calls and was wondering if you had managed to track down this in-call volume bug?
[Xperia Z3 Tablet Compact Original Android Developm] matthiassomay:
What a great ROM for my beloved Z3 tablet, thank you for your hard work and dedication. Other than some battery drain while asleep, I dont have any issues. When can we expect the support for fast charging?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Working on it, but swamped with work ATM.
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
Understood, this is a spare time effort - always a paingwhen work gets in the way of things we like doing ;)

Hey,

im not updated from the CM Rom from the other thread, cause i didn't used the device for a long time.

Can't find an update.zip ...

So is it possible to flash the newest version + gapps?
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
Follow-up, anybody know why my screen goes black when I flash a Germanic 23.A(...).291 ftf kernel? I can't install this becayse my kernel is from a Z3 mobile, so my device is recognized as another device... I had some trouble with shoey63's root & recovery guide, so after flashing the supplied mobile's kernel I couldn't flash back to the Z3TC kernel for my firmware because it made my screen black. More on that here: https://xdaforums.com/showpost.php?p=71469420&postcount=435.

Will try flashing back to the tablets kernel and hope it doesn't go dark.

Edit: Screen doesn't go dark, but I can't flash Lineage due to my device being recognized as a Z3 despite me having flashed Z3TC kernel's several times. Any tips would be appreciated. Build prop yielded no hints either.
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
The recognition in recovery has nothing to do with the kernel used. The recovery comes with its own kernel. You need to fastboot flash the boot.img from the lineage zip to the boot partition and then flash the TWRP for the Z3TC from korons AICP thread to the FOTAKernel partition. After that you can boot into recovery and flash the zip without a problem.
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
Thanks, good sir. Never flashed anything to the FOTAKernel, since I don't see a "fotak" option in Flashtool I'll just flash it as usual yes? I see the hotboot option or the "select kernel to flash" option.
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yes, but watch out for spelling and caps! It is

fastboot flash FOTAKernel TWRP.img
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
Didn't need to worry about the spelling, really. I simply did it via flashtool. Now my twrp looks a little different with a hydra or something on the splash screen :)

However, the rom won't install. I'm getting an error 7, cannot install this package on top of incompatible data, please try another package or run a factory reset. Will a reset do it, or do I need to do this via ADB (since you are mentioning spelling)?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Seems you need to do a factory reset. Using wipe in TWRP should do the trick. If it does not work, it may be needed to use flashtool and flash the latest stock FTF and do a wipe in flashtool.
[Xperia Z3 Tablet Compact Original Android Developm] kishe:
Every now and then when i try watching browser embedded videos, browser either crashes or my screen is covered with black artifacts and i have to reboot.

Ive tried factory resets and /system wipes plus reinstalls, but nothing has so far worked.

I got sgp621

You're ace, that did it.

Hi, I´ve bought a Z3 Compact Tablet with LTE, it´s my first Sony.

Actual there is Cyanogenmod 12.1 installed. When I start in recovery it shows a "Cyanogen Recovery"

Is it possible to install this ROM with this or is TWRP needed?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Are you using the browser from lineage or something like Firefox or Chrome? This is most likely a browser issue with hardware rendering.
[Xperia Z3 Tablet Compact Original Android Developm] jotade:
Nice ROM unfortunately screen mirroring is not working. Is there a workaround? Thanks
[Xperia Z3 Tablet Compact Original Android Developm] NTRNSTR:
[MENTION=615507]lowtraxx[/MENTION], have you ever considered using something like this to implement OTA updates into the rom? It's not very important but it would make updating a bit easier.
[Xperia Z3 Tablet Compact Original Android Developm] kishe:
It does that on every browser, even stock one. Is the gpu on my tablet breaking?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
In my newest test build it seems to be working. Seems it was a Lineage Bug, as I did not change anything pertaining to it

If it is the CM for the right model, you just should be able to use it instead of TWRP (but TWRP is recommended as it has lots more options). You also should consider upgrading to newest stock beforehand, to get latest bootloader and modem fw.

Not yet, but I am still working on it.

Is still considered, but has no priority ATM.

It is highly unlikely that your GPU is breaking. My guess is, that it is some driver complication with HW rendering. If you send me logcat after it happens I may be able to give you a more detailed answer (and maybe a fix).
[Xperia Z3 Tablet Compact Original Android Developm] blackdoG_:
Hi, registered to say thanks for your work lowtraxx, after initial hassle with TWRP I got it working on my SGP 611 (no gAPPS).

So far (a day of usage) it works fine, apart from 2 really unfortunate issues:

1) Camera has very high noise levels (understandable) but also it won't change focus at all (tried stock camera app, open camera and snap camera), rendering it completely useless. Is this a known issue? I remember reading in this thread that manual focus should be possible.

2) Audio issues: whenever any file is played there is this background hissing (noise artifacts) that is most audible on low volume playing. I can hear it even if volume is set to mute while the file is being played.
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
Two days in I can happily say this rom is the right one for me. No force closes, network speed and WiFi is fine. Audio issues (fluctuating), videos turning green (still need that logcat?) and lagging games probably something that will be taken care of in the next few builds.

Dev has done a tremendous job and boon for the XZ3TC community here.
[Xperia Z3 Tablet Compact Original Android Developm] bonzai80:
I bought mine yesterday and hope shipping doesn't take too long... I'll go for this Rom as well, I figured out, it's the best choice for the Sony. So far I used the LG 8.3 (v500) but this goes to my parents now. The Sony is a moderate update, not to expensive.

So here is a warm HELLO to all of you in this thread, I am the "new guy" - but not new to xda at all :D
[Xperia Z3 Tablet Compact Original Android Developm] xyunhox:
Thanks for your work. Rom is good.

I have a question.

V5 sgp621

I think Core 0 only works and the rest of the cores are not working.(cpu-z, cpu monitor)

Power saver is off.

Is this a bug? Can I fix this?
[Xperia Z3 Tablet Compact Original Android Developm] Quaicheist:
First off Lowtraxx, great rom.

I noticed that weather is now working in cLock widget in Resurrection Remix on onyx because according to the forum post https://xdaforums.com/showpost.php?p=71529825&postcount=636 org.cyanogenmod.weather.provider has been replaced with org.omnirom.omnijaws

Anybody having trouble with calls? Everybody who calls me is complaining about an echo, not signal related.
[Xperia Z3 Tablet Compact Original Android Developm] blackdoG_:
I can confirm that, also I have to speak directly into tablet's mic (or louder than usual) to be heard, not a big deal but still.

May be WhatsApp related, I am new to this, so I am not sure how to check for more details.
[Xperia Z3 Tablet Compact Original Android Developm] ccgx:
As far as I can remember, the rom comes with root? I cant login in to pokemon go and I think thats the problem.

Is there a way to remove root?
[Xperia Z3 Tablet Compact Original Android Developm] Quaicheist:
In About phone, tap Build number 7 times to enable Developer options. Then in Developer options -> tap Root access and set it to disabled.
[Xperia Z3 Tablet Compact Original Android Developm] ccgx:
It is disabled. Im searching for a way to remove root completly, like official lineage
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
try the "su removal" official of lineage, maybe it works. I tried it, and su was removed but I don't know if pokemon go works.
[Xperia Z3 Tablet Compact Original Android Developm] ccgx:
That was it! I could remove root without problems thanks to the official lineage su removal zip and pokemon go also works!
[Xperia Z3 Tablet Compact Original Android Developm] bonzai80:
If somebody needs root but at the same time wants to

use one of these secure apps like Android Pay or banking apps you could also try Magisk Root and under settings enable Magisk Hide. Then you should pass safety net check. Works fine on my Sgp621. :)
[Xperia Z3 Tablet Compact Original Android Developm] glimmling:
I replaced the Lineage OS root with Magisk yesterday, but the Safetynet check fails for me everytime (CTS profile mismatch). Magisk Hide and the systemless hosts file are enabled and I rebooted my SGP612 a few times.

It's the first time, I'm using Magisk. Any tips to pass the Safetynet test please?
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
I had the same problem, i read elsewhere that the problem could be that the selinux is "permissive", and change it to "enforcing", the problem is resolved, but I had troubles trying set it "enforcing" again and I got tired and i installed root common again.

My english is a little ****, sorry.
[Xperia Z3 Tablet Compact Original Android Developm] bonzai80:
How did you install Magisk? In TWRP or Magisk Manager? I did it with the manager (Playstore) and it worked for me. I left both boxes unchecked (force encryption and the other below) I am on latest MM Firmware.
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
I downloaded the magisk manager via playstore then downloaded the magisk 11.6 and at last flashed it with TWRP.
[Xperia Z3 Tablet Compact Original Android Developm] ztxgeol:
Why not make it a Lineage offical?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:

Thanks for your great work, lowtraxx.

I live in korea and using a korean locale, It doesn't detect 2.4ghz wifi with korea region code, so I have to change it manually to united states on every boot.

Echo issue I was reporting was noted as a bug last year in another LinesgeOS build.

https://forums.oneplus.net/threads/official-lineage-os-cm14-1-oneplus2-discussions-downloads.427906/

"Bugs found

Audio fx is missing

Call receiver hearing echo when call is placed in loudspeaker

Reboots while call waiting"

Odd nobody else is reporting the issue. In addition to echo, my calls are also constantly being disconnected the same way every time now - the call sort of breaks up with intermittent silence and the other party can't hear me then the call disconnects. Not a signal issue as this happens wherever I am. Will try flashing the rom again to see if it helps.

Would a logcat catch such an error?
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
Another Bugette for the list ... Not sure if this is in core Lineage or not ...

In Settings => Sound, when you set the default alarm ringtone to an audio file other than a file in /system/media/audio/alarms - it allows it, but gets ignored by the built-in clock

In addition, in the built-in clock, if you change the alarm ringtone for a given alarm to an audio file other than a file in /system/media/audio/alarms - it allows it, but doesn't "stick" when you exit the alarm UI - I get a default being set of "Rooster Alarm" ...

I have lineage installed but no twrp and no root
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
I do not have this issue in my latest build. I hope i will find the time to upload it this weekend. Then you can try again.

This sounds like a lineage bug. I will try to reproduce it, maybe it is also already fixed.

Lowtraxx, did you manage to reproduce the alarm issue I raised?
[Xperia Z3 Tablet Compact Original Android Developm] Rille_lkp:
Does anyone have a link to a working recovery for installing this rom (on SGP621)?

I have a SGP621 and i first tried with TWRP from https://twrp.me but was unable to install since model didn't match (scorpion windy instead of scorpion).

I then tried with stock kernel with TWRP from https://xdaforums.com/z3-tablet-compact/development/kernel-t3472019 but with that recovery, model name was "." so wouldn't install either.

Searching this thread i found the suggestion to use TWRP from the AICP thread (https://xdaforums.com/devdb/project/dl/?id=23870) so i flashed that to FOTAKernel and then boot.img from linage to boot but that just gave me a black screen.

I then flashed stock kernel with TWRP to boot again (no more black screen) and booted to recovery but then the installation fails with error "7" (which also seem device name related).

I'm currently on stock M with unlocked bootloader. Any ideas why flashing the boot.img from this rom to boot ends up giving just a black screen?

Edit:

As a last attempt, i relocked my bootloader, made a software repair using Xperia Companion and then unlocked bootloader again.

I then flashed TWRP from AICP thread, device boots fine but can't get into recovery. I then flashed boot.img to boot using fastboot and after that, only black screen.
[Xperia Z3 Tablet Compact Original Android Developm] bonzai80:
That`s what I did:

1. Download the latest zip (from this thread)

2. Download the latest TWRP (from [MENTION=5688409]koron393[/MENTION]'s thread - https://xdaforums.com/devdb/project/dl/?id=23870)

3. Unzip the ROM download (which contains the boot.img)

4. Boot into fastboot and fastboot flash boot.img to boot and TWRP to FOTAKernel (commands: "fastboot flash boot boot.img" / "fastboot flash FOTAKernel twrp-3.1.0-0-scorpion.img")

5. Fastboot reboot

6. On purple LED press VolUp until LED turns orange

7. Now entering TWRP you need to root device, follow the steps from this thread: https://xdaforums.com/z3-tablet-compact/general/how-to-t3528282

8. Now install the ROM & Gapps: go to advanced and side load the ROM zip (or you put the ROM zip and the Gapps Package on Micro SD before - copy directly from Computer on SD - without Tab!!)

- Between 6 and 7 do a complete wipe to be safe

- If you want GApps, sideload them directly after completing Step 7, do not reboot between!!!

For me this worked - maybe you just forgot one important step, goog luck man!:good:
[Xperia Z3 Tablet Compact Original Android Developm] Rille_lkp:
Thanks!

My problem is that when i reboot (step 5) i end up with a black screen and led only blinks red. If i flash another kernel like this one: https://xdaforums.com/z3-tablet-compact/development/advanced-stock-kernel-twrp-root-t2959720 or this one: https://xdaforums.com/z3-tablet-compact/orig-development/kernel-m5-kernel-t3289175 it works and i can enter recovery (but not install this rom due to model name).

I also tried the boot.img from the AICP thread but that only gives a black screen as well.

To make sure it's not TWRP, i flashed stock once again (and everything works). I then flashed boot from this rom and tried turning it on and i feel a short vibration and then nothing (black screen and no led).

Could it be that Sony's been using different hardware (like display vendors) and that the kernel used here doesn't support mine?

I've previously been using M-based CM on it but thought i'd test N.

Edit:

After flashing boot and twrp, i tried to boot into twrp using "fastboot boot TWRP_multirom_scorpion_3.1.0.0_3.10_201703.img" instead and when i do this, display turns on, i'm able to access TWRP using volup. When i try to install the rom however, it starts to install but then fails with error 7.
[Xperia Z3 Tablet Compact Original Android Developm] bonzai80:
On Step 5,immediately after reboot command you should start pressing Volume up button. Don't wait for the system to boot, it can't!

Did you put all necessary files to external SD (including root files)? Root first (3 zips like explained) then flash Rom and GApps
[Xperia Z3 Tablet Compact Original Android Developm] koron393:
LOS and AICP are made by 3.10 based kernel.

Stock and CM12 based are made by 3.4 based kernel.

My TWRP (in AICP thread) is made by 3.10 based kernel.

Other TWRP is probabliy made by 3.4 based kernel.

Please match boot.img and TWRP.img kernel version.
[Xperia Z3 Tablet Compact Original Android Developm] Rille_lkp:
Thanks for trying to help.

I'm spamming volup as i reboot but i get nowhere. I just get a black screen. If connected to PC while i reboot i see led blink red and then i get to fastboot mode again.

I starting to suspect there's something wrong with my unit. I get the same thing trying AICP using the boot in aicp_scorpion_n-12.1-UNOFFICIAL-20170324.zip and TWRP_multirom_scorpion_3.1.0.0_3.10_201703.img.

I also see the same thing with Paranoid Android.

Not sure why it works fine with stock and CM12 though.

The furthest i can get is if i do fastboot flash boot boot.img with AICP boot and then fastboot flash FOTAKernel TWRP_multirom_scorpion_3.1.0.0_3.10_201703.img. This gives me a black screen but if i then connect with fastboot again and do fastboot boot TWRP_multirom_scorpion_3.1.0.0_3.10_201703.img it starts up, i can enter TWRP but trying to install aicp_scorpion_n-12.1-UNOFFICIAL-20170324.zip gives error 7.
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
Lowtraxx, we hope you are still active on this ROM - I know you have been busy with work, life etc, but would really appreciate an update on when we can see the next build to iron out a few issues that are likely in the latest Lineage releases? Many thanks!
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yes I am still active. And I did the builds on the weekend. But they were not up to my personal standards, as the things I wanted to get fixed are not fixed yet and there were some regressions introduced which I fixed yesterday. I can do a build that just incorporates the latest source updates from Google and lineage later this week, but will have no fixes for the known issues, if you guys want that.
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
Interesting... my vote would be to wait until you are comfortable with the quality of the release (and that might mean you provide a release with one or two things that aren't fixed which have a "longer resolution time")... Thanks again for you support!!
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
It's all good. We'll hear from you when you are done. My call issues are pretty bad, but not bad enough for me to do another flash so i'll just wait for your next build. Have a great weekend when the time comes.
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Mah, even more work now :) Lineage integrated 7.1.2 and Sony dropped new binaries...
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
I guess we are lucky to have Sony so responsive via their Open Devices Program eh? :)
[Xperia Z3 Tablet Compact Original Android Developm] M!tch:
could someone please check if mhl is working with los 14.1?
[Xperia Z3 Tablet Compact Original Android Developm] Shimaran:
Hi there, thanks for you ROM ! I installed it following instructions in post #21 (was unable otherwise...)

So it seems responsive, however I do have some little bugs :

- the sound slider is broken, the volume is way too high at first whatever the slider is and then go backs to an almost inaudible volume

- the screen flickers like crazy when switching between tabs in Chrome browser

- adaptive brightness sets the brightness way too low in default settings (slider at the center of the screen)
[Xperia Z3 Tablet Compact Original Android Developm] Chima2:
Audio is a known problem, I believe. It will fluctuate on its own, and the lowest tends to be quite loud and then disappear before coming back again. Just wait for the next build, it might be improved.

Screen flickers I don't have, I do have problems with video playback at times and some graphical glitches in some games and certain times during borwing. Was GPU related if I recall, it might be taken care of in the next build.

Adaptive brightness I don't bother with personally, so can't comment there.
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Sound ist a problem that probably will remain a little longer :( I will roll back some of the changes I have done, which will make it better, but still broken a little.

Screen flickers I have never seen on chrome, so I would need a logcat to investigate.

I can set brightness a little higher in adaptive nice if required. Does anyone else see this?
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
I personally don't have an issue with either of these in the current (v5) build.
[Xperia Z3 Tablet Compact Original Android Developm] torben5247:
I don't see Any flickering.

But the backlight slider is very sensitive in the low backlight end. (hope you understand what i mean);)
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
So, binaries and 7.1.2 sources have been merged... Now lets see if it builds... And then on to fix all the stuff :)
[Xperia Z3 Tablet Compact Original Android Developm] Shimaran:
Flickers only happen with the latest Chrome version, and it seems it is not related to you ROM since another user reported the issue with the stock Lollipop ROM !

My issue with brightness is that the screen isn't bright enough when the ambiant brightness is feeble. I usually set the slider to the center of the screen, it has always worked with all my devices...

Oh, and I also have a bad battery life because I had twice more SoT with the Marshmallow stock Rom...
