That, I don't know. When I follow the instructions on Sony website on how to find out whether my bootloader is unlockable or not, I reach a screen with several lines of data, one of which says: :"Bootloader unlock allowed: No". From that I understood that simply following the Sony official bootloader unlocking guide won't suffice. I thought that's when firmware exploits come on the scene. And, doesn't the guide I posted a link to describe one of those exploits, with which I can install a custom ROM despite my bootloader being actually locked?

I apologize, as this is a question for a different thread, probably.
[Xperia Z3 Tablet Compact Original Android Developm] michael_hamada:
Yes, this rom already has built-in supersu, so you don't have to install manually.

But if you want to pass the saftynet check, you have to unroot and install Magisk.

From seeing a couple of Sony LTE tablet users mention this, the trend I notice is that bootloader unlock seems blocked by a carrier lock. You may find that carriers insist on this to prevent users from going to Sony in order to get root and hack the carrier lock. Have you got the carrier lock removed already?
[Xperia Z3 Tablet Compact Original Android Developm] Geralthewhitewolf:
Can someone please post a detailed video tutorial as to how to root and install this rom on z3tc as i recently bought it and really want to see nougat running on it

Thanks

I'm 100% certain I didn't buy the tablet from any carrier available in my country (Czech Republic). I always use Amazon e-shop to buy electronics, and so I did in the case of this tablet, too. What carrier should I contact, then? Also, the tablet was completely new, if that piece of information is of any value.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Everything you say sounds like you are taking the correct approach and that you should be able to unlock this, I'm at a loss. I bought my non-LTE version from a regular store and the Z4 tablet from Amazon. I followed the guidelines to unlock both as per the Sony developer site and it worked first time, very peculiar. If the tablet was purchased new I would complain to Sony support and see what they say.

Hello, thanks for your great work [MENTION=615507]lowtraxx[/MENTION]!

Just a major issue in my case: Android boots but freezes after few seconds, afterwards it reboots. Sometimes boots up corectly and everything seems to be OK. Gapps pico installed with clean install of your ROM.

I tried to wipe cache & dalvik few times after that, without luck.

SGP611 Scorpion windy - any solutions for this? What should I try?
[Xperia Z3 Tablet Compact Original Android Developm] jacktheriefla:
Try GAPPS Nano , i think Lowtraxxx mentioned that already.
[Xperia Z3 Tablet Compact Original Android Developm] Serial Kazama:
So i musst be stupid.

I was on latest Sony FW .291 with root. I unlocked my Z3C Tab boot in TWRP wipe the device and start adb sideload. But nothing happends.

So i flashed the latest TWRP image and teh device dont boot anymore.

Now i flashed the latest Sony FW .291, aktivated USB debugging and flash the twrp image again.

But i dont get into it.

Boot and VolUp but nothing happends.

I´m running Lineage on my Sony Z3 Smartphone and there works everything like a charm.

What do i wrong? <.<
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
i think, you have to flash the boot.img (which is inside the LOS.zip) and then flash TWRP custom and after that proceed to flash the rom normally through recovery.

I hope you can understand me due to my lack in english.
[Xperia Z3 Tablet Compact Original Android Developm] Serial Kazama:
You are da real MVP, wulfiss. Your English is exelent!
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Yes, IIRC on Sony bootloaders older than Nougat required that the boot kernel image be loaded to run TWRP, newer bootloaders *can* allow TWRP to run its own kernel.
[Xperia Z3 Tablet Compact Original Android Developm] beetmonger:
Just wanted to say thanks, again! Just came back to this after a long time away and got it working on my 612. For a while I was getting constant errors about compatibility when trying to flash. If anyone else is having this issue, I went back to stock 4.4.4, then flashed recovery to FOTA kernel, then boot image, LOS, and fixed boot image.

Hello,

Quick charging is disabled in this rom. Does it means that is it also disabled while the device is powered off?

Thx

Yes, it is also disabled then, as the "off" mode boots the same kernel.

After a few days i'm still happy with this rom.

However I've found 2 bugs:

* if bluetooth thetering is used, then wifi won't connect automatically. Not a big deal ( i've found workaround using third party apps to manage wifi and/or tasker intercepting some intent still working correctly ).

* my 3 button headset is working great on stock and an other phone, scancode for volume up and central button is the same on this rom (257).
[Xperia Z3 Tablet Compact Original Android Developm] MajorPlayz:
Bug: This occured in the 7 as well.

Bluetooth Audio (For All I have tested - I assume it it all data), comes out at something like 10X the speed! Was working fine in V5.

SGP612 Version of device

I have flashed the audio mod, but as I say, I believe it's data as well, so I don't know why that would affect it :/

i've found this old post whilst i'm searching for mhl in this thread. i'm still using official cm 12.1 on my z3 tablet because mhl is working very well. hope this information helps.

i would really like to switch to los but i could not do without working mhl because i often connect my mobile projector via mhl to the tablet.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
I guess LowTraxx is using a different kernel and that feature was dropped. Maybe we have harmonised kernel settings across z3 and z5 & newer devices. Newer devs keep usb disabled unless charging to avoid electrical issues when the open usb port is under water.

Out of interest what model is your mhl projector? Was thinking of getting one. Thanks.
[Xperia Z3 Tablet Compact Original Android Developm] M!tch:
it's an lg ph300 with a standard mhl cable (hdmi to micro usb and usb a for charging). the projector has a regular hdmi port.

Now, with flashing the ROM. when do I flash GApps? I know I have to flash the ROM then reboot to bootloader to flash the fix. Where does GApps fit in the process?

Thanks again.
[Xperia Z3 Tablet Compact Original Android Developm] Markyiptw:
In fact you can flash the fix within TWRP, like normal rom flashing but select "Image" at the bottom.

Also, the order of gapps and boot image fix does not really matter.

[Xperia Z3 Tablet Compact Original Android Developm] Columbia:
Hello. Flashed this ROM straight from CM12 with full wipe and micro gapps. Main issue is that tablet can't see SIM card now. Any suggestions? Thanks.

Edit: problem with SIM should be result of scoprion_windy firmware installation. But when i tried to flash LTE(scorpion) version TWRP showed an error which told that im trying to flash wrong version and that my device is windy (which is not apparently). So it seems that i can't flash LTE through TWRP.

Edit2: and TWRP can think that i have windy, because i installed TWRP windy from official repository. But it's the only version available. Where do i get TWRP for LTE?

Edit3: installed this scorpion TWRP to FOTA through fastboot, now i get error 7 when trying to flash any rom.

Edit4: Indeed problem was solved by flashing right TWRP and non-windy firmware. I spend more time than i would like to admit for solving that. In the end ROM was very unstable in my case and tablet often rebooted.

[Xperia Z3 Tablet Compact Original Android Developm] noname2no:
SGP-612 stands for Sony Xperia Z3 Tablet Compact (8 inches) not the phone named after Z3 which has its own xda forum and build. The Z3TC SGP-611/612 models (respectively WiFi/16Gb and WiFi/32Gb) definitely belong to the scorpion_windy family.

If you are indeed dealing with the Z3TC, the error may indicate you flashed the wrong recovery build and/or version. This thread refers to the right one.

In any case, I would recommend flashing the latest official ROM and firmware using Sony Emma tool. From this sane starting point you may proceed with the Lineage guidance.

This ROM (v2) is really rock solid. Android 7.0 is really nice. This build is stable: I experienced far less crashes than any cm-12.1 nightly build I previously flashed. Battery runtimes are great by default (without doze). I would not return to Android 4.4, 5.1 or 6.x.
[Xperia Z3 Tablet Compact Original Android Developm] sudman:
Thanks for the reply, I understand all that, I'm not new to this & it is an SGP612 I have. I've already done as you suggested but still get the same error, even though I successfully managed to flash a rooted Sony marshmallow zip to the device, so I'm not sure what is going on.
[Xperia Z3 Tablet Compact Original Android Developm] Choropy:
Although I'm not using this specific ROM, I did get the same error when I tried to flash another ROM. Turns out that I forgot that I didn't unlock my bootloader, so maybe check that out and see if it fixes your problem.
[Xperia Z3 Tablet Compact Original Android Developm] sudman:
Haha, yep your're completely right. Not used the device for so long that I'd forgotten that on this one I'd not unlocked the bootloader, merely rooted it. Which means that despite all my protestations that I'm not a newb to this, noname2no was right and I made the device think it was a Z3 because of method I chose to root the tablet. So apologies to noname2no, turns out I'm still a newb after all :)
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Just an update and FYI for you guys. I am still working on this, and there will be new releases. But my main goal is to get this as stable as possible and in the last few weeks many things in the ROM suddenly broke (due to changes in the blobs, changes Lineage made and other stuff) and I am patching it up here and there. I should get a rock solid build in the next few days (running the RC for it on my SGP621 to put it through its paces). I also added lots of the recommended changes here in the thread and still try fixing the alarm volume issue as well as up the speed performance-wise. So stay tuned ;)
[Xperia Z3 Tablet Compact Original Android Developm] M1chiel:
Thanks [MENTION=615507]lowtraxx[/MENTION] for your awesome work; I am looking forward to your updates! I have only one small issue with my SGP611: when I charge it while it is turned off, the screen doesn't dim. Hopefully this was already on your radar :).
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yes, this issue is partially fixed. The screen will dim and go off once now, but if you wake it up again, it will stay awake. Still working on this.
[Xperia Z3 Tablet Compact Original Android Developm] sudman:
So i'm now bootloader unlocked on my SGP612, but still cant get this to install through TWRP, keep gettting error 7 messages and complaints about this being for a Scorpion_Windy and either not a Scorpion or Z3. Think it's related to how I'm rooting the device and getting TWRP on there.

Anyone point to a good guide for getting root the rightway and getting this on to the device.

Cheers

Would i be right in thinking that fast charging doesn't work either?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Fast Charging is disabled by Sony on purpose, because they fear overheating issues as far as I understood it.
[Xperia Z3 Tablet Compact Original Android Developm] sudman:
It wasn't disabled in the last available stock build for this device as mine was fast charging till I updated to this Lineage build. So not sure whats going on. :)
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yeah, but stock is not a custom open source build. With stock everything is under Sony's control (including thermal management, charging voltages and the like), thus Sony takes no risks when providing open source code.

Hi, I just unlocked my bootloader and I want lineageos on my SGP621.

I dont know what to do next.

Which custom recovery do I need now and where can I download it.

Do I need an other kernel? I have the stock sony kernel.

How do I install it etc.

There are so many different download links and methods.

I just want a rooted lineagueos.

It would be nice if someone can help me. I would buy him or her a beer ;)

edit:

Ok I installed now twrp, lineageos, open gapps nano and supersu.

But this didn't fixed my actually problem, why I wanted to update to android 7.

My wifi isn't working since a week. I had the same problem a year ago. I had a locked bootloader with the stock sony rom (the newest android 6) and stock recovery etc.

Now I think it's a hardware problem :(

If someone know how I can replace the wifi antenna pleace contact me or is it maybe a software problem and I need an other kernel?

And people who knows!

Good afternoon

I have an international sony 8 inches SGP621 (Xperia™ Z3 Tablet SGP621FRBAE1), rooted with SuperSU Free v2.79, TWRP installed, 3.0.2-0, and running marshmallow 6.0.1.

Base band : 8974-AAAAANAZQ-00112-61

Security patch : May, first, 2016

Build : 23.5.A.1.291

3.4.0-perf-gc 14c2d5

I would like to update to lineage-14.1-20170728-UNOFFICIAL-Lowtraxx-scorpion.zip

Usually I manage to do that after reading ton’s of messages! But today I am lost.

Should I flash “lineage-14.1-20170728-UNOFFICIAL-Lowtraxx-scorpion.zip directly from my TWRP already installed, + boot fixed + open_gapps-arm-7.1-micro or Nano-20170916.zip, + to be still rooted, addonsu-14.1-arm-signed.zip?

Or from recovery? or bootloader? or downloaded mode and adb pushed from my computer?

English is absolutely not my native language!

Sorry for asking so many questions… Kindly yours from an old man
[Xperia Z3 Tablet Compact Original Android Developm] NamenIos:
Don't worry [MENTION=1695301]bvannier[/MENTION] your English is totally fine, certainly better than my French, but I am slowly working on that. I don't own this device, but everything is more or less the same on all Xperia models from Sony.

First you need to know if you bootloader is unlocked or not. To check that simply read the sony website for unlocking your bootloader, if you choose you device at the bottom of the website you get a seven steps of instructions on how to do that. If it's unlocked read the paragraph below. If you bootloader is locked, but i's possible to unlock the bootloader wait. You should backup your TA data first, just to be on the safe side. After that you can use the instructions on the sony website to unlock your bootloader. The unlock procedure will delete all data on the phone and will probably void your warranty.

If it's unlocked you can flash this rom in TWRP like you described, directly after that flash gapps and addonsu. For gapps I personally use micro on my older phone, recommended here is nano both should work there are minor differences. After that boot and see if it works. If everything is fine you can flash the fixed boot.img to make it possible to use usb for anything else than charging. The command for that is "fastboot flash boot boot.img", use it just like when you unlocked the tablet with boot.img in the same folder as fastboot.

Good luck and report back.

Bootlocker unlocked, TWRP installed.

So I can flash directly from twrp running recovery, just one more advice, why can't I also flash the bootupdate after lineage-14.1-20170728-UNOFFICIAL-Lowtraxx-scorpion.zip
[Xperia Z3 Tablet Compact Original Android Developm] NamenIos:
I think you can't flash a boot.img in TWRP, just zip files. I might be wrong on that. That was the only reason.

You might have to reinstall TWRP into the fota kernel partition, here is the img https://xdaforums.com/z3-tablet-compact/development/twrp-3-0-0-fota-kernel-t3345042 and I can't find a link for the recovery, only for the wifi version. But once you have an image the instructions are here: https://twrp.me/sony/sonyxperiaz3tabetcompact.html use the dd method. After that pressing vol down on boot should give you the very basic LineageOS recovery and vol up should give you TWRP.

edit: maybe you can use the TWRP for windy (the version without lte) with you tablet. Can somebody with the device chime in?

Think you for your help flashing this rom, but I gave up... I have been trying to flash it from my TWRP already installed and working, wrong message telling me that I can't because my SGP621 is not a "scorpion". Another way, I tried it from my flashfire Pro directly from my software... Wrong idea, stuck at boot SONY logo after this attempt.

Then ton's of different ways to make it recognized with fastboot from my computer, at least, blue light flashing and bingo, reflash the original "kernel, boot, and recovery" files called boot from here" https://xdaforums.com/z3-tablet-compact/development/kernel-t3472019"

after booting normally, developper options, replug in my computer then "fasboot reboot recovery" BINGO!

Recovery, then flash back my previous backup, OUF, back to normal.

Think you all of you for your precious time and effort.

So far I stay with 6.01, fully rooted with TWRP recovery.

[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
bro, what you need to do is simple, just flash to boot.img from the lineos.zip via fastboot, then flash this recovery https://xdaforums.com/devdb/project/?id=17990#downloads and after that boot into recovery and flash the rom + gapps.

you problem is that you have tried to install this rom with one recovery which only works with stock.
[Xperia Z3 Tablet Compact Original Android Developm] NamenIos:
I would guess the official firmware calls the device SGP621 (in the file /system/build.prop) and the recovery just reads it from there.

I extended the check so SGP621 should pass it too. You have to replace the file updater-script in the zip at \META-INF\com\google\android with my patched one and it should work. http://www40.zippyshare.com/v/vrSEEBTp/file.html Maybe you have to disable zip signature validation or similar if you change the zip, just in case you want to try.
