OK, I flashed the latest dated LineagOS 20180324, it still cannot connect to a hidden SSID, so I tried to reboot to recovery but it always rebooted back to LineagOS.

I then installed the official TWRP app from the google play store and then flashed what I thought was the latest download via the app. Seems it was an HTML file :crying:

The device no longer switches on, no Sony logo, etc. Now when I try anything via ADB, nothing is found, as is expected.

In fastboot mode, fastboot does not recognise the device attached.

using flashtool (9.18.6 or 9.24.4) the tool prepares a standard rom but fails with:

Current device : Unknown: Nov 30 2015/20:39:57 - CB5A1RS6XT - Unknown: Nov 30 2015/20:39:57 - Unknown: Nov 30 2015/20:39:57 - Unknown: Nov 30 2015/20:39:57

I assume the "CB5A1RS6XT" is some sort of device id used by flashtool, as the directory on my computer was created some years ago. In there is a TA backup, I can restore ta1.txt but not ta2.txt.

flashtool sees the device in fastboot mode but says:

02/021/2018 09:21:58 - ERROR - Drivers need to be installed for connected device.

02/021/2018 09:21:58 - ERROR - You can find them in the drivers folder of Flashtool.

Of course, despite trying all drivers, including google USB, I am unable to do anything to the device

I am on WIN10_x64, can create a Linux machine if need be to repair.

Any ideas how to get the device flashed with anything to recover/restore?

Fixed:

Linux is your friend.

I would like to report some issues, so that they are addressed, if possible, with the next version of the POLLUX version of the rom. I first installed the RR version of the rom, and I noticed the same problems. What I have noticed are:

1) WIFI cannot find all routers . Specifically it cannot find channels above 11, which is legal in Europe.

2) SD card has some problems. When, for example, I copy from internal memory to the SD card the files are copied, but it reports that the size of the files is 0b, which is actually NOT true. I have used various file explorers, and the result is the same......

3) Charging. When I charge the tablet, while it is off, it shows nothing. I realized that it actually keeps charging in the background, but there is no way to know how much it is charged and whether it is fully charged. An additional issue (more important I would say) is when you want to power on the tablet after charging. You cannot. After many trials I realized I can turn it on by pushing the volume + and power buttons for a couple of seconds together. I do not know why it works, but it does.

Ending this letter I would like to thanks the developer for bringing back life to this old but excellent tablet.
[Xperia Tablet Z Original Android Development] tres_linguas:
maybe somehow related to this, since it uses Wifi (direct): Miracast was not working in the build before. I wonder whether it was fixed in 2018-04-25 build (maybe somebody could report, plz :))

Also thanks to dev for supporting the old, but decent Tab-Z :good:
[Xperia Tablet Z Original Android Development] CaHbKaUp:
Miracast is working fine, my tablet with 8.1 casts to my bravia tv over wifi without any problem. Be more specific what is not working in your case ?
[Xperia Tablet Z Original Android Development] tres_linguas:
With 04-06 build (don't know about 04-26 one since I went back to RR Nougat), the tablet tried to connect to the Miracast receiver (Microsoft Wireless Display Adapter, 1st generation), you could see that a connection was in the process of being established both on the tablet ("cast" symbol appeared in statusbar) and on the monitor in which the adapter was plugged in (it said sth like "connecting to android-XXX"), but the connection was not eventually established. The process was automatically reinitiated a couple of times until it was finally abandoned by the tablet.

Logcat is here: https://xdaforums.com/showpost.php?p=76175989&postcount=31 this was created on RR, but it was the same issue with Lineage and crDroid.

as I said in this post: https://xdaforums.com/showpost.php?p=76081898&postcount=56 it does work with chromecast, which needs sender and receiver to be in the same wifi. With normal miracast, however, which does not require this (only wifi needs to be turned on on android device since it uses wifi direct), it did not work, at least with me.

However, thanks for the reply and the excellent development :o

I used linux mint on usb

get the latest TWRP for pollux(_windy) as a .img (I saved this to the USB)

from a terminal:

sudo apt-get install android-tools-adb android-tools-fastboot

plug in device

from a terminal:

adb devices

fastboot flash boot twrpfilename.img

unplug device

power on device

I then went back to windows and used flashtool just to make sure again

In my opinion, more pleasant than that LineagOS 14.1.

[Xperia Tablet Z Original Android Development] a_nd_s:
Thanks

I used a previous 14.1 unofficial on my pollox-windy tablets ( 2 of) , and moving to this 15.1 was great. So many thanks for making this possible.

There are a couple of things I have noticed, the green led on the power button is currently winking at me as I type - surely if quiescent these should be off?

I have to power off the tablets completely at night to avoid the light. The power consumption on 15.1 seems to be greater for some reason - if left for a while it drains the battery way more than the 14.1 which I could leave for hours with no noticeable reduction in battery.

I had the odd situation of one of my tablets refusing to start with the power button for quite some time, but I got it into TWRP with power/vol+ - the other identical tablet did not have the problem ( they run the same image restored from a TWRP backup). So I have no idea what was going on there.

Apart from that, as a daily driver it works superbly . .

Thanks again

As GPU is not stable I overclock it

It again moves to lower values as a result my games lags

[Xperia Tablet Z Original Android Development] Azazel Azay:
Oh, it has been 2 years since i last tried playing games on this tablet. I used to play mc4, asphalt, real racing when i bought this tablet... They used to run just fine. The last game i played was gta sa, and this tablet managed to run it in low-mid settings but not in high settings.

I think this kind of performance is acceptable. S4 Pro SoC is quite old now. Its older than even OG SD600 & SD800 series. It was featured in 5 years old Galaxy S4 i guess. And its successor was SD600 not even SD800.
[Xperia Tablet Z Original Android Development] amritansh singh gautam:

So far only tablet tablet power on procedure is very unusual (need to hold power button together with power up).

This is just a deepfelt thanks to the developers who literally saved my tablet from a premature death. It just didn't perform anymore and even the install of an app like Firefox would crash the tablet. Also the battery performance was awful, WiFi reception and speed was very poor and it felt that the ssd was superslow too.

And I know what I'm doing, so no mal or spyware on the tablet either, but just an out of date os. I had already rooted the device and had the bootloader unlocked and installed a cyanogen rom some years ago and that improved things for a while, but eventually it detoriated to the point where i would give up on my 700 euro device.

And then I stumbled upon the Lineage rom. Because the device had already been rooted, I just went and installed this rom and the update to lineage os went without a hitch. I did not have much expectations but just gave it one last try.

With this OS everything works better than the original Sony image. I can install any app without a problem and the performance is back at original levels. Imagine I was about to give up on the tablet and basically throw it away. Now I'm writing this message on it and it hasn't crashed once since the three day I'm running it. Just about any original feature of the tablet works and even better than before.

I know you developers who create these amazing ROMs don't really get paid for this, but I hope my heartfelt thanks helps you to keep doing what you do. I really appreciate your efforts.

Thank you.

Thanks, this build was very useful for specific aspects of my app development, whereas the Xperia Tab with stock ROM and Android 5 was next to useless because it heavily restricts usage of the USB OTG.

My app deals primarily with USB modem use on Android, so it would be nice to get standard OTG functionality, including use of USB hubs. I can't make the OTG port work in the current release - is that a hard limitation or is it possible to add the feature in a later release?

Thanks again!

Just minor problem with the WiFi connection: not seen 2.4 GHz SSIDs.

Real Racing 3 seems to work as in stock ROM.

I will upgrade the information.

Thanks indeed!

Update information: there are problems with the SSID detection. I have a Tplink repeater (RE450) and the tablet just detects the 5.0 GHz SSID. In the área there are many 2.4 SSIDs and the tablet just detects few of them.

I have reset the WIFI option in Oreo without any improvement.
