Which Security Date has got this ROM.

Wound you like to update this ROM monthly with newest Patch level ?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Valera1978:
Current security update is october 2019.

You can monitor new update in: https://github.com/LineageOS/android_build/blob/lineage-16.0/core/version_defaults.mk , PLATFORM_SECURITY_PATCH define

Usually a new update appears on the 5-10th of the month (in lineage code) and after it I'm building new version.

How do i install this?

sorry to be a noob but this is my first time rooting an android device in about 8 years.

I have rooted by T320 and have super user.

I have installed the TWRP app.

I have odin.

I have all the downloads suggested on both my PC and my Samsung SD card.

WTF am i supposed to do from there? :) Do i install the mondrianwifi i find in the TWRP app if, so to boot or recovery? Or am i supposed to install the version the author linked. I hav read multiple articles but they don't explain what i am doing, why, how i should choose my options and they are all seriously out of date (given the age of the tablet)

Help!? Can someone give me a breadcrumb trail?

---------- Post added at 03:13 PM ---------- Previous post was at 02:51 PM ----------

Ok i figured it out by a lot of poke and hope and got lucky.

I have the new firmware on with micro apps.

Was non intuitive how long the tablet takes after first reboot to get everything ready and WTF is that slider / circle animation - i thought it was telling me to slide my finger from right to left (that was up for like 2.5 mins the first time) luckily i just waited.

On first use lots of apps reported crashing most stopped but BT app was in infinite reboot.

Did hard reboot and the BT app is still infinitely rebooting along with android.process.media

Trying a factory reset, use TWRP to wipe device (all but SD card) and reinstall to fix....

---------- Post added at 03:32 PM ---------- Previous post was at 03:13 PM ----------

now its hung at the strange animation for more than 10 mins and power button does nothing? What next?

Another wipe and re-install not connected to USB seemed to fix it.

These fixes are for T320-Model and both Roms LineageOS 16.0 and 17.1.

I'm using the Android 10 ROM by [MENTION=2047373]Valera1978[/MENTION] and it doesn't work there, but if it works here I may switch.

Thanks for the quick reply. Yes, I think it's the same under Android 10.

Encryption has nothing to do with TWRP recovery

You have some major misconceptions I think. If the TWRP versions you flashed are not capable of decrypting /data then it is their flaw not the ROM's fault.

This can not be! If the ROM fails to encrypt the tablet then it is a ROM and/or device flaw. But TWRP is not at all involved in the encryption, meaning it can neither positively nor negatively influence the encryption process. Conversely, it would mean that none of the previous LineageOS versions could have been encrypted since TWRP is missing decryption support. This is not the case obviously.

In order to be able to freshly install a new ROM AND get rid of previous encryption Wipe -> "Factory Reset" is not enough. It "Wipes Data, Cache, and Dalvik (not including internal storage)". But it will not alter the encryption and it will not touch /data/media, which is pretty much the internal storage that contains your precious personal files (photos, videos, downloads etc.).

If instead you use Wipe -> "Format Data" it "will wipe all of your apps, backups, pictures, videos, media, and removes encryption on internal storage". (Make sure to backup internal storage e.g. via ADB!).

Thereby you are not only deleting all /data including /data/media but your are also getting rid of the encryption. Then, regardless of your TWRP version, you can install an old Custom ROM like LineageOS 14.1 and encrypt it. Or, alternatively, install a new one (LOS16 or LOS 17.1) and forego encryption because it is currently not supported.

If it is not possible to decrypt an encrypted /data partition then that is because the recovery or TWRP version you are using does not support /data decryption.

However, even with a TWRP version lacking the /data decryption functionality, you should always be able to format data and a decrypted /data partition, install a new ROM and (if possible) encrypt it. But the latter has nothing to do with or is not influenced by the TWRP version or its capabilites.

I haven't tested under Android 9.0 so I can't know for sure if it works here, but on the Android 10.0 "sister" ROM split-screen seems to be unavailable.

Since I've seen you on the thread for both ROMs, are you sure you're testing on 9.0 one?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
Yes, I'm sure - I've got two devices :)

Isn't here anybody else who can check if split screen works on his device with this build (and report it back here)?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
Obviously we're using different devices. I've just made a test: LineageOS 14.1 encrypted -> booted in TWRP (and entered password so that TWRP can read from / write to /data) -> factory reset -> installed LineageOS 17.1

After the flash the device is still encrypted:

During first boot on LineageOS 17.1 I have to enter decryption password that I have set on LineageOS 14.1

Booted in LineageOS 17.1 I can check device is still encrypted

All files and folders on internal storage are still there

This is just one specific test, but I remember this behaviour for all past flashes on my encrypted device (and there were many of them :D). The first time this didn't work was with the current versions of LineageOS 16 and 17.1 for SM-T320. Here, either TWRP or the ROM (or both) has problems handling the encryption.

TWRP: "Factory reset" vs. "Format data"

Right, if you just factory reset in TWRP then encryption will remain untouched. And since /data/media a.k.a. internal storage is not touched, all files and folders should still be there.

Interestingly, you might have described an interesting way to use encryption in LOS16.0 or LOS17.1 despite the fact that these two versions fail to encrypt an unencrypted /data themselves! I will try to use that same upgrade path (Install LOS14.1 -> encrypt -> install LOS17.1) and see if LOS17.1 takes over the "pre-existing" encryption flawlessly. Thanks for the idea!

PS. In my previous post I was unfortunately not precise enough with my remarks. I have edited that post now.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
With installing stock -> encrypt -> flash LineageOS 16 or 17 I wanted to do the same. But the step from stock to LineageOS perhaps is too far. I wish you have luck with your idea. If it works it would be fantastic. If not, maybe we'll know more about working / not working encryption and maybe a good developer can fix the actual problems.

How did you manage to have "LineageOS 14.1 encrypted"?

Did you only encrypt in Stock ROM and then flash LOS14.1 with the encryption still intact?

Are you using the T320 Wifi-only version? I was not able to encrypt the T325 version with neither CM13 (old crpalmer ROM), nor LOS14.1, let alone 16 or 17.1. Probably only possible with Stock ROM.

Note that LOS16 and LOS17.1 only work with SeLinux permissive.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] pocketrule:
As encryption is broken on T320 (which I'm using) I've had to do this test with another device (smartphone). Please excuse me for not having this made clearer, for me it was logical that it had to be another device where encryption worked. But I didn't think that this could be misunderstood, as here we talk most of the time about the T320. But as you've tested CM13 too, it's astonishing, that encryption is broken for such a long time...

LOS17.1 indeed crashes immediately if you want to enable SELinux. But on LOS16 you can enable it e.g. with the inbuilt terminal (which can be enabled in developer options) and su [enter] and setenforce 1 [enter]. So far I've encountered no problems with SELinux enforcing. If you mentioned it with possible effects on encryption, I believe encryption is not dependent on SELinux state.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] mjdeluca:
Battery performance is good, but note that the base Lineage code seems to have a bug that does not properly put WiFi into deep sleep when needed on (at least) T320. For me, battery drain while the display is off is around 1% per hour - note that this is not only for the build in this thread (16) but also earlier Lineage builds (such as the 14 build from phoval). If WiFi is turned off manually (I have a Tasker script that disables WiFi when the display is off), battery drain reduces to around 0.1% - 0.2% per hour.

I'm not aware of any High CPU issues with the 16 build. I believe this is still an issue for the LOS1 17 build by [MENTION=2047373]Valera1978[/MENTION], but there is a workaround described in the thread for that ROM.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] C0nvert:

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] mjdeluca:
I set up a task to turn WiFi off, and then a profile that monitors the display state - when display is off, it calls the task to turn off WiFi. There's probably a more sophisticated way to do this, but hoping this points you in the right direction.

Encryption not working on any mondrianlte/wifi Custom ROM

Yeah, it is really frustrating that encryption does not work with any of the available Custom ROMs. And since less and less people own and use it, the odds of finding a developer making it work are going to zero... :(

Even after granting location access, no app can autodetect location. For example I have one weather app that tells me first that GPS is not set for high accuracy mode. It then forwards me to the system "Location" settings. In there, "Use location" is enabled but "Battery saving mode" is off. When trying to turn "Battery saving mode" on, "Use location" disables itself and "Battery saving mode" is greyed out. GPS is nowhere to be seen in the settings. Very strange. Anybody seeing the same thing or knows of a fix? Here are the two options I can choose, neither are working:

[IMG="Use location on"]https://www.dropbox.com/s/qioxoi82ft1sau3/Screenshot_20200526-183057_Settings_resize.png?raw=1[/IMG]

[IMG="Battery saving mode on"]https://www.dropbox.com/s/yj1rsa52xdjr8j6/Screenshot_20200526-183430_Settings_resize.png?raw=1[/IMG]

BTW Google Maps is using the GPS fine and GPS test apps also work, so direct access to the GPS seems to be fine just not the location services.

[Edit] OK it seems to be an Android P thing. Enabling GPS for apps using location services is hidden in Advanced - Google Location Accuracy - Improve Location Accuracy. Just if anybody else is stumbling across this. What an improvement to the old, I dunno, obvious style, eh?

I second that! I bought a new used replacement TabPRO for my broken one at the same time I switched to this ROM, and would get random reboots as soon as the battery was under 70%, especially outside when the screen was at max. brightness. I replaced the battery with a new one and now it's been rock solid for me. BTW the old battery was from FEB-2014 when they started selling this thing, so no wonder it's been acting up after over six years.
