I do think that Magisk has been tested a lot more thoughtfully than this ROM so if anything Magisk would've caused a bootloop. Other users have successfully flashed 15.2.

No I followed the Instructions part in the first post. There is nothing on the first post that indicates anything has to be done with bootloader/FOTA. Why are there 2 different installation guides? Nothing tells us which one someone should use.

However I have flashed Linage OS 14.1 in the past and had to update the bootloader there.
[Xperia Z3 Tablet Compact Original Android Developm] ux50jp:
You need to update bootloader to stock 23.5.A.1.291, otherwise bootloop or half brick.

I had the same problem like you. Good luck!
[Xperia Z3 Tablet Compact Original Android Developm] sewalt91:
I flashed the latest stock bootloader for LOS 14.1. Also I don't got a half brick (led and vibration work), I got a full brick (led dead, no vibration). Can't even get into fastboot mode. How did you fix your situation?
[Xperia Z3 Tablet Compact Original Android Developm] ux50jp:
In my case, only orange or yellow light was on. I couldn't use fastboot mode either.

So I connected to PC and managed to flash stock 23.5.A.1.291, then unlocked it.

Then, followed the instruction(2nd guide). Now all works fine.

this whole process takes time!! I lost all Sunday afternoon.
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
that is very sad, have you tried to connect to the pc and see if there is any kind of sign of in flashtool? because I have had a problem like yours, but when I did that, the tablet was in flashmode and I was able to flash stock with flashtool.
[Xperia Z3 Tablet Compact Original Android Developm] perler:
I didn't read (or to be true, didn't understand) "Crypting Storage" as not working. I know now, that you meant "device encryption". Problem is, after trying to encrypt the device it is in a bootloop.

I tried a complete factory reset from TWRP and reinstall without success.

what should I do?
[Xperia Z3 Tablet Compact Original Android Developm] koron393:
Format or erase userdata from bootloader.

And re install ROM.

But device encryption is not works now. You should never try it...
[Xperia Z3 Tablet Compact Original Android Developm] perler:
whatever this even means.. the trick for everybody else: a simple wipe from TWRP doesn't do it, you need to use the option "WIPE/format data". afterward install ROM and Gapps and you are good to go.
[Xperia Z3 Tablet Compact Original Android Developm] fred0r:
I dont think its really dead - you didnt flash the boot.img first - happend to me also.

Follow this

i was able to repair mine, but you need to Flash the original Sony-Image first.

So LED was working on your device? How did you access flashmode?

Problem is my device is not recognized when I plug it in, also no matter the Key-combo the LEDs will stay dark and no vibration occurs.
[Xperia Z3 Tablet Compact Original Android Developm] milox_x:
I occured same problem but I accessed flashmode and flashed Sony Stock ROM. Download flashtool, download sony stock rom and flash it. To access flashmode for flashing press volume down key and insert usb cable at the same time.
[Xperia Z3 Tablet Compact Original Android Developm] sewalt91:
I got flashtool and most recent stock rom in tft format already. If I press Vol- and insert the USB then nothing happenes. Flashtool won't recognize it at all. I've tried almost 3 hours yesterday to get into flashmode. There's a small yellow button you can press with a thin nail when you open the microSD-card cover. It's a hard reset button that is directly connected to the battery. Not even this thing works.
[Xperia Z3 Tablet Compact Original Android Developm] fred0r:
Any chance that AICP will sometimes also support the Z3 Compact Phone ?
[Xperia Z3 Tablet Compact Original Android Developm] perler:
silly idea: did you try another USB cable? I tend to use only supershort cables as even normal length cable tend to be flaky when flashing..

The SGP612 is wifi only but the ROM seems to think it is on mobile data (apps that try to avoid downloads via mobile data think so). is this a known bug?
[Xperia Z3 Tablet Compact Original Android Developm] harborxperia:
Let the tablet completely drain. Let it sit unplugged for a week or so then try again. I had the same thing occur, tablet appeared dead. It wasn't, just locked up.

How do I start in TWRP?

Wie starte ich in TWRP?
[Xperia Z3 Tablet Compact Original Android Developm] 1971sunny17:
Tablet einschalten warten bis LED lilla leuchtet dann vol+ drücken. Sollte klappen. Allerdings TWRP muss in FotaKernel eingebunden werden.
[Xperia Z3 Tablet Compact Original Android Developm] RedSimply:
Where can I get the FotaKernel? Would you explain that to me.

Woher bekomme ich den FotaKernel. Würdest Du mir das erklären.
[Xperia Z3 Tablet Compact Original Android Developm] CrazyPeter:
Installed on my SGP611 and working extremely well, very smooth, no major problems. Very impressed.

Anyone know how to get rid of the SMS hangouts nag?
[Xperia Z3 Tablet Compact Original Android Developm] sewalt91:
Back from the dead!

Was able to recover my tablet from a deep-kernel-brick.

According to this thread here you'll end up in a lock-up when you do a hard-reset (Power + Vol-Up for 10 seconds until 3 vibrations occur) when kernel/bootloader is damaged. Nothing will work at this point, tablet won't be recognized, won't charge and won't reset. The only way to get out of this is to clear the RAM. On old devices you'd have to wait until the battery dies or disassemble it and disconnect the battery manually. However the Z3 Tablet has a hardware-button that is directly connected to the battery. Open up the SD-Card cover and you'll find a small yellow button reading "OFF":

This will disconnect the battery for as long as you hold it.

Install latest flashtool

Install flashtool drivers from installationPath\Flashtool\drivers and choose "Flashmode Drivers" + "Xperia Z3 Tablet Compact Device Driver"

Start flashtool and click the "XF" button to start XperiFirm

Download the latest firmware for your device and provider

Click the "Flash" button in Flashtool -> Flashmode -> select your downloaded firmware -> tick everything in "Wipe - Sin" section -> Flash

Plug the USB cable into the PC but not into the tablet

Press and hold the yellow hardware "OFF" button with a pointy object for about 1-2 minutes, don't let go!

Press the Volume-Down button while still holding down the "OFF" button

Let go of the "OFF"-button and connect the USB cable to your device while still holding Vol-

If you did everything correctly the device should show up and flashtool will start flashing

If an error occurs just try to flash again, keep holding that Vol-Down button

If your device wont be recognized but shows up as "S1 Service" under device manager then you didn't install the drivers correctly

i feel like some kind of magician. Why did nobody mention the hardware-button? Could have saved a week worth of downtime.

I had it sitting for a week, lost about 20% charge. Mine had ~90% charge when I bricked it. Would take more than a full month...

Good you're fine with it now!

Great lesson nevertheless...
[Xperia Z3 Tablet Compact Original Android Developm] ElGrandeFez:
First of all: Great ROM. Has really breathed new life into my tablet. :good:

One thing that is missing for me though is aptx support. The only zip/magisk modules I've been able to find seem to be 64bit, so don't work. Is this something that could be added or is anyone aware of 32bit libs that can be installed (ideally via magisk)?
[Xperia Z3 Tablet Compact Original Android Developm] Geralthewhitewolf:
hey guys,

i was trying to install twrp on my sgp 611 followed all steps from the op and it is booting into twrp but i forgot to download the rom to my tablet. the rom is present on my pc only so how can i send the rom to my tablet and flash it.

if i connect my tablet in twrp mode to my computer, it detects my tablet but i am unable to send anything to it.

i was thinking of booting into system but op said don't boot any stock rom. In adb devices my tablet doesn't show so can't use push command.

Can anyone help me, i am pretty freaked out by now

Thanks
[Xperia Z3 Tablet Compact Original Android Developm] M1chiel:
You can copy the rom on an SD card, insert it in your tablet and install it from there.
[Xperia Z3 Tablet Compact Original Android Developm] CrazyPeter:
Enter adb sideload mode from twrp and send it from your PC. that's how I did it.

https://xdaforums.com/showpost.php?p=75262771&postcount=4

The instructions worked fine for me
[Xperia Z3 Tablet Compact Original Android Developm] Geralthewhitewolf:
Thanks guys, I installed the rom, everything is up and running now
[Xperia Z3 Tablet Compact Original Android Developm] koron393:
Oreo now supports aptX natively... but seems like to some codecs is missing.

Unzip attachment zip and copy codecs to /system/vendor/lib/ in TWRP.

Modify settings in Developer options

I don't have any aptX devices. Please test it!

If successful I will merge into ROM.

hi everyone

Why I flash this ROM on my sgp641 then use facebook and netfilx app only can watch very low quality video?

youtube app is work I can change video quality so not problem .

but facebook looks so bad because only can watch 180p

netflix same too

I from taiwan my english is not good hope you know what i say.....

Trebuchet is the launcher of CyanogenMod / LineageOS. A workaround would be to install a custom launcher like Nova or Lawnchair to enjoy your widgets.

[Xperia Z3 Tablet Compact Original Android Developm] jeffcpc:
Hi, I am a newb here and would like to get some advise or sharing on flashing my Z3TC. I got a unrooted SGP641 with 23.5.A.0.575 bootloader and would love to try this AICP Oreo custom ROM. I went thru this thread and learned that I MAY need to update bootloader to stock 23.5.A.1.291. Is this mandatory even for SGP641? Because I tried to let the tablet check if there is any system update for 23.5.A.1.291 but the response is no new system updates any more. Therefore, would like to check if anyone knows the answer. And if I should unroot the device now with 23.5.A.0.575 or I should update to 23.5.A.1.291 first and then unroot the device.

In addition, I saw there are different flash instructions at post #1 and #3. Following is my plan and would need some advise (questions are with "jeffcpc:"):

a. Figure out if need to update bootloader to stock 23.5.A.1.291 and the unroot

b. Download TWRP and ROM for scorpion (since SGP641 is similar to SGP621)

c. Following the instruction at post #3 as shown below:

1. Download ROM zip [jeffcpc: download the scorpion ROM and TWRP but should I put them in internal storage or SD card is also ok?]

2. Extract boot.img from ROM.zip [jeffcpc: and put it in internal storage, right?]

3. Reboot into bootloader mode [jeffcpc: so, I just need to restart the device and it will go into bootloader mode, right? Any key pressing needed?]

4. Flash extracted boot.img (fastboot flash boot boot.img) [jeffcpc: would assume this is an option after getting into the bootloader mode, right?]

5. Flash recovery to FOTAKernel (fastboot flash FOTAKernel TWRP_xxxx.img) [jeffcpc: err.... this is still an option within the bootloader mode, right?)

(Don't boot any stock ROMs.)

6. Reboot (fastboot reboot) [jeffcpc: would assume this is an option under bootloader mode. Correct?]

7. Press volume up button when LED light turns "pink" and boot into recovery mode (LED turns "orange") [jeffcpc: ok, this one is clear to me :)]

8. Push ROM.zip [jeffcpc: how to "push" the ROM stored in either internal storage or SD? Is it like file transfer?]

9. Wipe Data/System from menu [Jeff: assume this is option in the recovery mode]

10. Install ROM.zip from menu [Jeff: also assume this is option in the recovery mode]

11. Reboot [Jeff: also assume this is option in the recovery mode]

This is my very 1st time to flash a custom ROM and would like to be crystal clear before doing it because if my Z3TC becomes a brick, a newb like me really do not know how to get it back to whatever mode and there are too many conditions with probably different dependency.

Therefore, would like to check if my understanding and the procedures listed are correct before proceeding the flashing.....

Thanks a million for any recommendations, suggestions or advise given or shared.

Tausend Dank!!!
[Xperia Z3 Tablet Compact Original Android Developm] Geralthewhitewolf:
Is your bootloader even unlocked?

And update your stock ROM to android marshmallow that will update your bootloader
[Xperia Z3 Tablet Compact Original Android Developm] jeffcpc:
It is not unlocked yet but I have got the code from Sony to unlock it already. Would like to make sure the planned procedures are clear and correct before flashing my device.

Following is a screenshot of my device info - it is on Marshmallow 6.0.1 but with bootloader 23.5.A.0.575. I am not sure why the bootloader is not 23.5.A.1.291 Maybe because it is a SGP641 but not a SGP621?
[Xperia Z3 Tablet Compact Original Android Developm] sebarkh:
As a rule of thumb: never flash a device with a rom for a different model. Period.

Can anyone say something about the standby battery drain?

How many percent’s the tablet loses over night?

Thanks!

[Xperia Z3 Tablet Compact Original Android Developm] ADSFAaron:
I flashed this rom to my Z3TC SPG641 and it work fine on my device.

First, unlock bootloader (I used flashtool flash the version to 23.4.A.1.200 and unlock because this version can easily root and install recovery )

Second, root and flash recovery.

Third, make a flashable zip (23.5.A.1.291) and flash it. It should contain root and recovery. I made it by myself.

Then, follow the step on page 1. There will be more details on flashing this rom.

I hope this would help.

Hi there !

I noticed some kind of "buzzing" sound that can be heared on very low volume, on high volume it's almost inaudible. I don't think I had that while on stock firmware.

I also have issues while setting the brightness of the screen : in automatic mode, it's either too bright or too dark, and in manual mode the lowest brightness setting is brighter than in automatic.

Other than that, the ROM is very good ! Nice work ! Having Oreo on such a good tablet is so nice :)
[Xperia Z3 Tablet Compact Original Android Developm] koron393:
(Darker) automatic brightness, that's the specification.

I will not fix it.

Guys I am stuck :/

I did all the steps above and have an unlocked bootloader.

I flash the boot.image then the TWRP for Scorpion (I got 621).

then when I do the fastboot reboot, I see a red light and push and hold volume up then I see it flash red then green and nothing else happens. If I try to turn on the phone it gives like a vibration pulse and nothing.

Help please :/

PS My phone shows as Android ADB Interface when connected in fastboot mode (blue light) but I can issue the commands like fasboot devices and get replies back so I am completely lost as to why this is not working.

After flashing stock rom with Flashtool I was able to follow the steps from Post #3 and this time it all worked. Also installed Magisk 15.2

Now time to test this fully! :)
[Xperia Z3 Tablet Compact Original Android Developm] dape16:

Can you try to have an app open, like Chrome or a game, and see if it refreshes/restarts when you connect and disconnect the charger?
[Xperia Z3 Tablet Compact Original Android Developm] tommes-d:
I can only see a short sort of display flickering on some apps, not all.

Firefox and Osmand+: short flickering

Kurviger pro and gmail: no reaction

I would not really state this flickering as an app restart.

Also no problem after dirty flashing but I did wipe cache first before installing the new ROM. Any other items needed to wipe too to make Z3TC more stable?

BTW, the battery interface is new with more options vs the previous release but somehow I feel battery lasts shorter time. No exact number or info on the battery life comparison result but just a feeling. No sure if anyone feels the same.

Im now on LineageOS 14.1 Android 7.1.2

1. First it is necessary to update bootloader to stock 23.5.A.1.291 ?

When I do this is bootloader then still unlocked ?

2. when I following the 2nd installation manual I flash the gapps after the rom directly ?

3. the grz gapps I need is for ARM ? not ARM64 ?

thanks for helping me

Erik
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
1. Yes, you need to do that, and yes the bootloader will remain unlocked.

2. Yes, it's the same proccess that you did for install LOS. Wipe, flash Rom, flash gapps.

3. You need ARM gapps, it would be great if our tablet were 64bit but not. haha
