There must be ways around that. Apps like zetaTorrent can use the external SD card without formatting it as internal memory? Also, there's a Magisk module called ExSDCard Access Enabler that should make it work universally.

For me, musts are working bluetooth and good battery life *when using the tablet*.

Thank you for the great ROM!

Followed the installation guide and everything went smooth (TWRP-3.4 > lineage-17.1-20201002-UNOFFICIAL-karin)

I know that the Snapdragon 810 runs hot by design, but I was surprised that it throttles back strong already from 50C (after 10 seconds of load). My old Xperia Z Tablet goes up 80C before throttling.

Is there any trick besides lowering the max core MHz to minimize the throttling/ extend starting throttling temperature?
[Xperia Z4 Tablet Android Development] sabar_op:
It use custom power management (ported from angler) and underclock the cores.

New update with experimental camera working in here (latest date) using :

- Snap : taking picture ok but broken for video cam

- Open camera (disable flash): taking picture ok, video cam is laggy

- Simple camera : weird result during taking picture

- Others : not tested yet.
[Xperia Z4 Tablet Android Development] Blackholefighter:
Is there any specific reason for setting the limit so low? (maybe noob questions)

Other electronic devices usually are not throttling at 50C.
[Xperia Z4 Tablet Android Development] sabar_op:
Not sure about that as I am not a dev who create it. I just use it instead of using original power management. The kernel also can be use original as well (without underclock).

But I am happy with this setting because it give balance between performance and power consumption for daily use.

By the way, do you remember I was telling that WiFi 5 GHz doesn't work with some regions. Now I can define the problem more clear. Los17 WiFi 5ghz doesn't work with some radio channels. For example, with 36 work and with another doesn't. Check it with padavam router firmware. Hope this information would be useful.

Hi,

I need your help. :angel:

First of all, I’m really glad that this tablet hasn’t been left alone and made for newer Android. :good:

Secondly, I would like to use this ROM, but I can't install TWRP. :( I have two devices with custom ROM (OnePlus One, ASUS Nexus 7 2012), so I know how it works, but this device has no official TWRP. A 3.1.1 TWRP is mentioned on the first page of the forum, but there is a 3.4.0 version in the shared folder. Should I use this? What is the exact procedure for TWRP installation? This? https://wiki.lineageos.org/devices/karin_windy/install

Sorry for my bad English! :fingers-crossed:

Thanks in advance for your help!
[Xperia Z4 Tablet Android Development] DHGE:
You could follow the link in my footer to learn something (still valid).

You must use TWRP 3.4. The older version do not work nice with the recent ROMs.

I only use TWRP for flashing ROMs nowadays. So I did not install it.

I merely adb reboot bootloader and then fastboot boot TWRPxy.img and then flash the ROM from my SD card.

battery drain problem, can't doze (20201116 )

Hi, thank you for your spendid work.

I have made a clean installation of the 20201116 version. The process was seamless.

But I am having a serious problem with battery drain, tablet with a good battey (95% of health) can't last a single day of combined use. It seems like:

1) tablet is not being able to doze properly

2) when turned on the cpu usage is high (like 30%) under no real strain.

Analysing battery I am getting crazy usage of 500-600mA when tablet is turned off (should be around 30-60mA)

and 1200 - 2500mA when tablet is on and with no perceivable intensive tasks in the foreground / background.

ad 1)

I have analyzed the wakelocks in different configurations (network on/off, wifi / bluetooth on / off, airplane mode) but came to no evident conclusion regarding potential culprit.

I suspect it has something to do with the wifi networking because if I disable Wifi and keep BT the battery usage during sleep is ok even if constantly connected with BKB50 keyboard.

ad 2)

htop is showing two generic system_process [/I ] processess eating up the CPU (up to 35%)

For doze problem I am using a workaroud - application called naptime, it works very well, tablet deep sleeps properly but it's not a fix, just workaround.

EDIT: I have just concluded that the biggest difference naptime is actually doing for me is just disabling Wifi during sleep. It confirms that the probem is somehow connected with Wifi networking.

For high CPU usage I have no workaround now. Battery saver doesn't change anything.

Please share anyone if I am not the only one having such problems. I am using Open Gapps Pico.

Maybe those tweaks in kernel mentioned before have some direct impact?

I can't say if setting SELinux to enforcing from permissive had any impact because I haven't tested previous builds.

EDIT: I have finally concluded that the sole reason for battery drain is just WIFI being turned on, the problem occurs even if I am not connected to any network, the device is virtually working offline. I have never had such problems with other android devices.

Some kind of problem with wifi drivers maybe?

BKB50 Keyboard Touchpad two-finger scrolling

There was a question about it some time agoi but it was unanswered among other issues.

[MENTION=2705776]sabar_op[/MENTION] Do you think will it be ever possible to implement two-finger scrolling for BKB50 keyboard touchpad for Z4 Tablet or it is impossible due the closed source code that was providing such function in original Sony stock roms?

very clear, thank you

i am little confuse on the bootloader unlock

i see the tutorial is

On the device, dial *#*#7378423#*#* (*#*#SERVICE#*#*) to launch the service menu.

Go to service info > configuration and check rooting status – you can only continue if it says Bootloader unlock allowed: Yes.

then

Follow the instructions on Sony’s official unlocking website to generate an unlock code for your bootloader.

Use your code to unlock the bootloader of your device

so in the real life should be enable bootloader unlock > boot into fastboot mode > then request the unlock code on sony website > using the unlock code on PC to unlock the bootloader

am i understanding it correctly?
[Xperia Z4 Tablet Android Development] alex009988:
I don't remember exactly as I was doping it ones upon four years ago.

But you must unlock bootloader by fastboot, flash twrp and lineage kernel by fastboot and boot to recovery then flash the ROM.

Hi there

Eventually, I conlude that there is a serious problem with this ROM (at least for me):

It can never go into the DEEP SLEEP. that's the reason for absolutely abysmal battery performance when tablet is not in use and is supposed to be sleeping.

I have use all the last builds with a help of such apps like Naptime (disabling everything including BT and WIFI), Greenify and monitored the system with BBS for wakelocks - all to no avail.

Returning to stock for now till the problem is fixed. I hope it gets better.

I am attaching some screenshots presenting the critical problem:
[Xperia Z4 Tablet Android Development] frode_:
I will have to agree, the battery life isn't very good with this rom atm. Gsam doesn't give me any clues other than the android system draws alot of power. Using the latest build too. I measured it one day to -40% in 12 hours while idle.
[Xperia Z4 Tablet Android Development] jelbo:
I hope this can be fixed. I still like this tablet and I'm using stock Android 6.0.1 still, because it has no sleep/battery issues.

Hi I am new to kernel tweaking. I am trying to compile the kernel for Xiaomi redmi 5a for latest miui stock rom from source located at

https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/riva-o-oss

After flashing the boot image created with compiled kernel , everything except wifi works.

Google search revealed that it is a common issue and one suggestion is to put the wil6210.ko (wifi related) file from compiled kernel in to system/lib/modules which doesn't work.

What confuses me even more is that even in if I delete the wil6210.ko from system/lib/module when the stock kernel is running , the wifi still works . It Seems like this kernel module has no effect on wifi.

But deleting the vendor/lib/modules/pronto/pronto_wlan.ko breaks wifi for stock kernel that came with the rom.

But compiling the kernel from source doesn't generate such files.

one related info at https://github.com/Genom-Project/android_kernel_xiaomi_vince-3.18/issues/2

I found a guide at https://github.com/MiCode/Xiaomi_Ke...#download-qualcomm-android-enablement-project that talks about wifi module.

The download seems to be to big and maybe too many unnecessary files will be downloaded. Tried to init and sync the repo. It seems huge. So if nothing else works will try this.

https://github.com/supercairos/android_device_xiaomi_land/issues/1#issuecomment-259458071 seems to provide a shortcut technique. It asks to download the prima folder from https://source.codeaurora.org/quic/...opensource/wlan/prima/tree/?h=LA.UM.5.3_rb1.1 (I can replace the h value to my kernels tag) , merge it into the source and then compile it to generate the prima_wlan.ko . I did so and also added CONFIG_PRONTO_WLAN=m ( m to compile as module) but such file is not being generated after compiling.

So please, if anyone went through something similar , help me with your recommendations.,

After this I went to download mode but I cant seem to actually download firmware onto the phone from odin, it doesnt show an ID: COM either.
