I have this model SO-05F. How do I check this setting in current Android?

I will also appreciate if you can guide me how to perform those recovery and flashing points mentioned in the installation thread. Which commands I need to run to flash and do recovery on Windows system?

Thank you again.
[Xperia Z2 Tablet Original Android Development] L3ibnitZ:
I don't know this version and I can't tell you if this ROM is suitable for your version. Looks like this is a Japan version/model.

Everything you do is at your own risk!

If you don't know how to flash ROMs and you are not willing to search the world wide web for a "how to" I can't help you.
[Xperia Z2 Tablet Original Android Development] gurupak:
Thank you for the reply. I think its the LTE version i checked the specs on GSM Arena website and the cpu that uses LTE is the one I have.

Can you please just write the commands using the adb or fastboot to flash the TWARP, ROM, MAGISC files? I can't find those commands here to run. In the first post its just mentioned to run those file without any shell commands. Is there any other post that I can look for it?

Thank you again.

Compass not working

Good morning, I would like to thank and congratulate with all the team behind the "Android Ice Cold Project": this Rom is amazing! I never thought that my old tablet would one day be able to run Pie and also so smoothly.

I wanted just to ask you one opinion.

The compass doesn't work and the magnetometer doesn't show any sign of life neither. Before flashing this Rom, I soft bricked my device, so I flashed a .291 stock rom (if i recall right) and then I flashed this Rom. The fact is that I didn't know what version my tablet was on so in my first attempt I flashed a branded one.

Could it be the reason? Or someone else has this issue?

Everything else seems to work just fine.

I have the LTE version by the way.

I thank in advance whoever will choose to help me out.

Regards.

How can I install this AICP rom on docomo Xperia Z2 tablet?

I am unable to install twrp on it, after booting into fastboot, the devices isn't showing.

Can this ROM be install in this docomo tablet?

Any help plz
[Xperia Z2 Tablet Original Android Development] milvokar:
hello,i have the same problem ,no boot to twrp,have you already sloved the problem?
[Xperia Z2 Tablet Original Android Development] Ryū Kenden:
Do you come from another rom or from stock?

In case of the former, Have you tried to flash the latest stock rom available for your device first?

And did you use the recovery from the CarbonOS thread?

That's at least how I resolved the same problem.
[Xperia Z2 Tablet Original Android Development] milvokar:
I’m already at the version aicp 14.0-20190426,but i can't updater by ota,and into recovery.
[Xperia Z2 Tablet Original Android Development] Ryū Kenden:
Have you tried to flash the recovery via ADB?
[Xperia Z2 Tablet Original Android Development] milvokar:
yes,i have tried,it dosen't work
[Xperia Z2 Tablet Original Android Development] Ryū Kenden:
What doesn't work?

The method? Or you can successfully flash the recovery but without actually obtaining any change?

It could be, I'm not sure, that you have to flash the recovery using flash FOTAKernel instead of simply kernel. Maybe someone with more experience can tell you better though.

Bear in mind that, at least from what I've experienced, you have to keep for a long time the combo of hardware keys even if you don't see any led whatsoever.

don't forget, to flash the twrp for the z2 it is " fastboot flash boot ", not " fastboot flash recovery "

Update: Reboots still happen when installing apps

Hey there! I downloaded the ROM yesterday, loving it so far Thanks to all the dev team for their hard work and for continuing keeping our lovely tablet alive! However, here is a issue I experience with this ROM.

!!! EXREMELY IMPORTANT BUG: BOOT LOOP WHEN DEVICE IS IDLE :: SLEEP EQUALS TO REBOOT !!!

"Every time the screen goes black, by either idling for 30 seconds or by pressing the power button once, the device reboots after about 1 minute. Then after it reboots and the screen goes black if device is idle, it reboots again after 1 minute and so on".

AICP ROM rooted with Magisk via twrp recovery when flashed.

No charging battery or usb cable connected or messing with anything.

This does not happen with Resurrection Oreo custom ROM or Sony stock rom.

model: SGP512

build: aicp_castor_windy_p-14.0-WEEKLY-20190906.zip

Update 1: G apps Stock caused the reboots. I fresh reinstalled the ROM sing the Pico G apps and no reboots so far.

Update 2: Reboots on sleep still happen whenever I install an app from Google Play. Definitely a problem with the ROM, since I've tried everything including clean flash, Pico G apps etc. The only way for reboots not to happen is keep the ROM completely intact after flashed and NOT install other apps.
[Xperia Z2 Tablet Original Android Development] L3ibnitZ:
[MENTION=10118258]Dikaiotis[/MENTION]

I do not have any random reboots. The ROM is working perfectly fine except miracast/stream display.

I suggest you to do a clean installation of the ROM.

[MENTION=6425591]SpiritCroc[/MENTION]

can we help you to fix miracast with some logs etc or is it not possible to fix it?
[Xperia Z2 Tablet Original Android Development] SpiritCroc:
Try flashing latest stock ROM, then clean flash latest AICP

Miracast support was removed by Google for AOSP 9, but recently added back by lineage and also AICP, so I'll re-enable it device-side for the next build.

If it doesn't work in next build, a logcat might help.
[Xperia Z2 Tablet Original Android Development] Dikaiotis:
Reboots still happen when installing apps

ok. Seems like the g apps (Stock) that I had installed first were causing all this mess with the random reboots. I tried a clean ROM installation using the G apps Pico suggested here and no reboots so far :o I'll write back if anything weird occurs in the meantime. Thanks :good:

Edit: When I installed some apps the reboots on sleep started again :eek: If I keep the ROM intact however, with G apps Pico only and nothing else installed it seems to works fine.

I'm having problems with the android access framework. Cannot write to external sd card and cannot get write access from fx file manager etc..

Error: ACTION_OPEN_DOCUMENT_TREE not implemented on this device
[Xperia Z2 Tablet Original Android Development] SpiritCroc:
Have you disabled or uninstalled any necessary system apps like e.g. DocumentsUI?
[Xperia Z2 Tablet Original Android Development] oguzbatu:
What apps did you install? I am running with pico gapps and some downloaded ones from playstore and some of my own apps and have no problem.

And also always install pico gapps since the other packs might cause some problems. You can install other gapps you want from playstore after you are done with the setup.
[Xperia Z2 Tablet Original Android Development] olympusandy:
Not that I can see. My sd card is sdcardfs, not fat32
[Xperia Z2 Tablet Original Android Development] Dikaiotis:
Some very basic ones from the play store such as Google Wallpapers and Google Photos. Then I changed the wallpaper using the g app. The reboots started... Also if I mess up with the default launcher settings (icon placement, style etc.) it causes reboots again. Only if keep the ROM completely intact there are no reboots.
[Xperia Z2 Tablet Original Android Development] olympusandy:
I have fixed it with a re flash. Can't quite work out what broke it though.
[Xperia Z2 Tablet Original Android Development] oguzbatu:
Did you use a live wallpaper ? I installed one of the Google's live wallpaper and it works fine without a problem.

And I can't really say anything about rom settings since I only changed theme to dark and didn't do anything else.
[Xperia Z2 Tablet Original Android Development] L3ibnitZ:
Updated to sept 13 weekly and Miracast is working flawlessly. Thank you very much for your continuous support and great work :good:
[Xperia Z2 Tablet Original Android Development] Ryū Kenden:
I also confirm that Miracast seems to work fine.

If I may ask one thing to the developer, can anything be done for the recharging screen? When the tablet it's powered off and I connect it to the recharger, after the AICP recharging image shows up, the screen became black but remains turned on indefinitely.

Thanks in advance.

Display turns on when charging by Magnet DockingStation

When i put my z2 on the magnet dock the display always turns and stays on.

I'd like it to stay off when charging. Any idea how to achieve that?

Thanks for your continued support, [MENTION=6425591]SpiritCroc[/MENTION]. Happy Castor windy user here. I too have had the charging issue (screen on while charging etc) Even when this tablet is turned off, it seems to drain battery. I just keep it on all the time and try to keep it charged. Can't complain for a 5+ year old device. Still very usable for me as a rooted Android tablet that's lightweight.
[Xperia Z2 Tablet Original Android Development] nicky-xda:
Do you want to tell us that you are bringing android 10 to out Z2? :)

There is a work-around for this: instal the Apps: Sony Smart Connect + Screen Lock Pro, set profiles for start/end actions (for the accessory "charging dock") and select the screen lock app as the link.

Hi everybody,

Hope I'm posting at the right place . . .

I flashed this great ROM a few days ago with TWRP 3.2.1-1 and it's working flawlessly . . . Kudos to SpiritCroc ! :)

Now it's time to root my tablet. As I used other root methods formerly, I have questions about Magisk install after reading Topjohnwu tuto: https://topjohnwu.github.io/Magisk/install.html

- do you guys simply flash the Magisk zip with TWRP ?

- or do you use the "Boot image patching" method ?

Note: I have checked my Z2 Tablet (Castor-Windy) and it's a NON A/B partitions device.

Many thanks for sharing your experience ans skills !
[Xperia Z2 Tablet Original Android Development] L3ibnitZ:
Yes :good:

No, it was never necessary because I prefer to flash with twrp.
[Xperia Z2 Tablet Original Android Development] creditabricole:
Hello L3ibnitZ,

OK that's very clear.

Many thanks for your feedback :)

My turn to give some feedback: I installed Magisk simply flashing it with TWRP and everything is OK.

Don't know why such a complicated procedure is indicated on Magisk tutorials. If somebody has got simple A partition device, the magisk install is pretty straightforward.

Same issue here, it reboots almost every time I turn off the screen
[Xperia Z2 Tablet Original Android Development] 5halzar:
Same also here, just tried to load it in last night.

Just to ask, I only flashed the ROM and Full GApps pack from TWRP, didn't do the root.

Is there a component where the Root is required?

Edit: I did try and fastboot flash the rom before re-flashing and still nothing. this is for a Castor build.

[Xperia Z2 Tablet Original Android Development] bvhoesel:
'Found' my Z2 tablet again after putting it 'away'. The ROM looks and feels great. Nice work.

Only I also experience reboots after screen off. Latest ROM with pico gapps.

Did install several apps before I noticed this behavior.
[Xperia Z2 Tablet Original Android Development] Dior DNA:
Hi all, just to let you know: some people (like me) apparently exist who do not suffer from reboots (after screen off, latest ROM with pico gapps). So, now, what is different, I really do not know :(, I recall I always flashed latest Sony firmware. But if that is the tie break, I do not know or dare to claim.
[Xperia Z2 Tablet Original Android Development] bacon612:
Same. I'd be curious to know why we don't have issues and other do
[Xperia Z2 Tablet Original Android Development] Br4no:
Happy user here, without reboots. But I have been updating only for quite a long time, so no clean flash of the latest builds.

If I could help somehow to solve the reboot issue others suffer by providing some info, let me know.

Bro I have this problem too and after a lot of searching I think it is something about the country code (or something related to countries like Iran) and I think you have the same problem as me (by looking at your name :D) I haven't found any solutions yet to fix it totally but as said in the thread I found a way to access wifi connection on my tablet :

1. Turn on airplane mode

2. Restart your tablet

3. Turn on wifi and hopefully it will work for you too (you can turn airplane mode off after that but if you turn your wifi off and on the problem is there again.)

Do you use the lte model? I use the lte model and also have 0 problems it runs even better than stock. Most of the people that have problems are mostly non lte model as I can see.
[Xperia Z2 Tablet Original Android Development] L3ibnitZ:
No problems here with non LTE model.

The only "problem" I am aware of is that the display is always on when u charge the device while it is turned off. It is not a big deal because I have a cover and u can turn the device on to deactivate the display while charging.
[Xperia Z2 Tablet Original Android Development] bacon612:
Mine is not LTE. Don't have the reboot problems

After updating to 15 November build the tablet died. It won't charge, turn on, vibrate, anything. I don't know wheather the update was the reason for this, but it happened :( Do you guys have any ideas how can I revive it? I hope it's not a hardware issue.

hmm i'm skipped the last week update, coz there are no significant changes ... but i could try it anyway

[MENTION=8614630]Godecki[/MENTION] , hold the volume up or down button , then connect the tablet to your pc via usb .. if u hear a notification sound , you'll know that your tablet isn't dead ;) the update then just messed up your boot.img .. simple connect do flashmode ( push vol up , then connect usb cable ) and flash a new boot.img .. that should do it.
[Xperia Z2 Tablet Original Android Development] Godecki:
I did try button combinations, tried connecting to PC in fastboot, flashmode, nothing works. The LED doesn't light up too. It's completely dead.

Hi. Sometimes it happens to me too. In this moment my Z2 tablet is dead. Wait for few days because the battery is empty. Then if you push power the led lights red colour. Then charge the tablet. When is charged the tablet works well. Be patience. Is a battery isue.

Thanks for the response! However, I would like to point out that:

- it has never happened toe before

- it was charged just yesterday and the battery has never depleted during screen off (I have some battery saving features installed)

- it doesn't accept charge, neither by USB port nor through magnetic port, I checked it with multimeter

I'll wait anyway, I would like to avoid opening the tablet if not necessary.
[Xperia Z2 Tablet Original Android Development] Dior DNA:
same here, no issues
[Xperia Z2 Tablet Original Android Development] jeryll:
try this

you should probably try this (helped me with similar problem (device looked dead - no respose whatsoever to any of my action (well it was not, just stuck in "special" download mode)))

- Open the SIM card slot cover.

- Using the tip of a pen or similar object, press and hold down the OFF button for 120 seconds, ignoring any vibrations, and then release the OFF button.

- Charge the device until a charging icon appears on the screen.

- Turn on your Xperia™ device.

- Note	Do not use overly sharp objects that could damage the OFF button.

I just installed this and it worked great for a while. After some time when I had installed several apps I also got the "reboot issue". It's not rebooting here though. When the screen turns off, the tablet turns itself off.

I have 32gb wifi version (castor windy). Before I had installed 23.5.A.1.291 then Resurrection Remix Nougat. I then wiped system, cache, data and art/dalvik cache. I flashed this rom, then pico gapps and lastly magisk.

Are there any debug logs or something I could share to help find the problem?
[Xperia Z2 Tablet Original Android Development] Godecki:
Thanks for help, however I did what you told me and still no response. There were no vibrations whatsoever during holding down the off button. When connected to the charger, it doesn't charge (checked this with multimeter).

Charging issue: Display Sleep time setting reset / not saved?

During the charging, after some time, the display begins to go on and off, and the charging LED goes sometimes off and on as well, and it is then not possible any more to turns the display on beacause it show for shorter than ~1 second and immediately goes off.

I have then to re-start the device, but after that the setting: display/sleep/time always gets reset, so that no setting is set (although i had it set before to 2 min.). And the display turns off already after some few seconds.

The above repeats each time when charging.
[Xperia Z2 Tablet Original Android Development] SpiritCroc:
Which build? Does it behave the same on builds before and after November 18th? Are you talking about charging the device while it is turned on or off, and does it make a difference? If it happens in the latest build when the device is on, can you get a logcat?
[Xperia Z2 Tablet Original Android Development] solved:
the "display on and off" thing while chargin' , i've got this since a couple months .. once u reach around 85% the display starts to go on and off.

Actually since the start of this issue, i never fully charged the tablet again ;) i usually charge till 90% and then unplug it.

But i don't need to restart the tablet, works fine with that.
[Xperia Z2 Tablet Original Android Development] nicky-xda:
I'm updateting regularly, but always "manually " download the builds from the link here in the first posting.

The issue showed up some 2 weeks ago, probably on the build 15/11/2019 (on the builds 22/11 & 29/11 still there), i'm not sure if it was before or after Nov 18th, but it was definitely not there at the beginning of November and before. Earlier i was able to charge until 100% without any issues.

Dirty downgrade to the build 8/11/2019 - without wiping DATA - does not solve the issue any more, although earlier i did not have the issue on the build 8/11.

It behaves about the same with display off or on, i've checked it and can reproduce it with display on, display sleep set to 30min., as following:

- it charges normally, LED is on, until ~93-94%, at this level the LED begins to blink (and go off for some seconds now and then) in a irregular way until it goes off permanently

- with the display still on, the battery level goes down to ~91-92%, at this point the LED begins to blink again in a irregular way and after some 2-3min. the LED turns green on and the charging begins again until ~93-94

- now the whole "procedure" begins again as above.

LOGCAT: if still needed, what should i do exactly?
[Xperia Z2 Tablet Original Android Development] SpiritCroc:
Can you try a clean flash of the build before November 18th and also of the latest build?

Can you try out a different charger/cable?

For taking a logcat, here the guide from our AICP discord group:

Taking a LOGCAT

1. We have the possibility to take logcats without any extra app in the ROM. It is located in the "AICP Extras" app -> Menu -> "Log that ****". Mark the needed logs and hit "Engage".

1a. The inbuild system uses "hastebin" web service to give you a link after logging that can be posted here in the "#bug_reports" section.

THE ABOVE PROCEDURE DOES NOT WORK FOR EVERY LOG. The webservice has a limitation on log size, so that it might display a message stating that "your file exceeds maximum length".

1b. With getting the error mentioned above, you should then chose to ZIP (=Compress) the log, upload to a cloud service of your choice (GDrive, Dropbox) and link the File.

2. If you don't want to use the build-in option, please use either Matlog (https://play.google.com/store/apps/details?id=com.pluscubed.matlog) from the Play store or SysLog (https://play.google.com/store/apps/details?id=com.tortel.syslog).

ALL THE MENTIONED APPS REQUIRE ROOT and ARE FREE.

3. The different logs in short:

logcat: the logoutput of the Android system since boot (needed every time)

radio/modem log: the log output of your System / BB / RIL communication (rarely need, so only on request from us)

kernel / hardware log (kmsg / dmesg): the kernel messages (sometimes needed on request)

4. You can upload your log rom the Apps above to your GDrive, Dropbox or any cloud service and just post the link here WITH a short description what happened.

... one last thing: please do not expect an answer in 30 seconds, Logs are long, errors are hard to track and a solution / fix might even take longer.

Note: a short & picturered guide can be found here: https://photos.app.goo.gl/ZEWxRnmtchzHLGZ76

Edit: after a couple of days, there is some life in the tablet. When connected to a charger, the LED shines with red colour for about a second and turns off - and that's it. I found out, that the tablet now charges with 0.1A, however I am afraid that this current only is used to power the short curcuit. Any ideas what do to next, when it's showing a brief signs of life?
