Hi, is it possible to flash the t550 version on t555 using the same files ? Twrp recovery and rom's zip . I don't mind loosing sim card support
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Unfortunately it has not worked well in the past and I don't think it will be any different right now. They do not use the same kernel config. The last test person told me the gt510lte build would be working fine, so I guess you can go ahead and try it out. I am not able to test it, because I own the gt510wifi only.

Have a nice day though!

Maybe check out the Galaxy Tab 4 devs (the tab 4 too has the sd400). They actually need help so you might wanna join their small team called "LightningFastRoms" (the project isn't limited to the tab 4 of course).

We're running the MSM8916, the MSM8226 is even older. I doubt the devices share a single chunk of config files. Once I was thinking about a cooperation with the msm8916.com team I inherited my device trees from, but they seem dead on the lineage-17 track. And I don't see the need to switch from stable Lineage right now when it does not boot tbh.

Hi Virsys,

My t550 seems to have just dropped volume (both speaker and headphone) out of the blue. It seems to be a software issue as when I play a video through Kodi, I can turn up the amplifier setting from within Kodi to increase the sound back to original levels.

Could you link me the mixer path file so I can manually copy it to/system/vendor/etc or give me some pointers on what to try
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] pvandenh:
Update : Tried again the next day, and found a single mirror (thankfully).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] chrislind:
I'm having the same problem. Were you able to get the file?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Do you have apps like viper for those purposes installed and something messed up there? The mixer paths file should not change in any way, you can double check with the repo though. Does the issue persist after a clean flash?

https://github.com/VirsysElectron/a...ob/lineage-16.0/configs/audio/mixer_paths.xml
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
The file has been pushed to the FTP server in Quebec, those files usually have one mirror only. But the download speed was impressive and I got the file with Firefox immediately. Have you tried another browser? In case more people have problems I'll switch to a different hoster though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sir nom:
I did have viper installed but sound still worked and all of a sudden it dimmed (full volume media is at about half of normal). Tried overwriting the mixer paths with the one linked but still no good. Neither is the full install (haven't formatted data).

Just installed latest build and noticed SELinux permissive? As I was updating from your prior enforcing build, are there any plans to release enforcing builds again? Thanks again for you work on the T550.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
It is correct that recent builds ship with SELinux permissive again. There were SELinux related camera issues on newer builds and people complained about that. Together with other issues fixing this is a time consuming task, and right now I am still investing most of my free time in Android 10 tests. On the new version we will need a rewritten policy anyways, I do not want to hassle with that twice. But I have not forgotten and it is still on the roadmap.

I will provide an update with the new security patches soon. Have to fix a few bugs there with the new sources before releasing though. As always, my time is limited. Have a great day (:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mr3p:
I was unaware you were working on Android 10 :) As such I totally understand the preference to focus on policy for newer Android version. Thank you as always for your hard work.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Here you go: https://sourceforge.net/projects/virsys-android/files/gt510wifi/LineageOS/

Made the switch to sourceforge because some of you were having difficulties downloading the latest AFH releases. I have some good news, finally I got Android 10 running on the SM-T550! There are audio as well as camera issues right now and I need to merge the recent local changes with my GitHub though. For the interested ones of you there will be a new thread with the alpha Android 10 builds soon. The new builds will be crDroid which is based on LineageOS. In case you do not like the new system let me know, it is no big deal for me to use the device tree in pure LineageOS as well. Will keep you posted.

boot issues

Thanks to the contributors for giving the opportunity to run a new OS on a device (SM-T550) that is no longer supported by the manufacturer.

The installation works fine for me. I do not detect any issues in the logs that are displayed in twrp (I am using twrp-3.3.1-0-gt510wifi.img.tar). Before I flash I format and wide everything (except of the sd card, which contains the zip files) and I cannot wipe usb otg, because of the error "E:unable to wipe 'usb-otg' -- unknown file system 'auto'".

I tried with two rom versions: lineage-16.0-20191231-UNOFFICIAL-gt510wifi and lineage-16.0-20200318-UNOFFICIAL-gt510wifi .

I tried with and without Gapps (micro and nano verions) but this all does not make any difference. I also removed the sd card while booting.

The issues eventually is that the boot animation starts and lasts for several minutes before the device switches off. In some cases with the 20200318 it reboots into the twrp recovery, but normally it switches off.

So, there is some kind of flaw, likely because I am doing something wrong.

For info I am providing access the log files (dmseg and recovery) on dropbox.com:

/sh/mvbcxrir9rkvml4/AADnqaDxwc9N27j200K_9VJya?dl=0

(As a new user I cannot post a complete link, just add the above line after the .com)

The log files point to some warnings and issues that are not displayed on the screen.

I would really appreciate if someone is able to spot what is going wrong.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] bilatche:
Is the same for you to have to clean the ram (by killing apps) in order to be able to use the device correctly?

Without that, I have the device wich is totally freezing.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lololab:
I have exactly the same behaviour : same twrp version, tested with 20191231 and 20200318.

On my T550, the packages installs fine, but never finish boot. The boot animation is displayed on long time until shutdown.

I will try the older 20190112 version to see if it works.

I have never posted in a forum before so treat me gently! By trial and error I have got DRM working (level 3). This is what I did (I realise that some of this could be achieved more easily and that I may well have added more files than I needed, anyway):

Copied files from Samsung Galaxy S8 running stock Pie 9.0 rom as follows:

android.hardware.drm@1.0-impl.so (system/vendor/lib/hw – permissions 644) ***

android.hardware.drm@1.0-service (system/vendor/bin/hw – permission 755) ***

libwvdrmengine.so (system/vendor/lib/mediadrm – permissions 644) ***

libwvhidl.so (system/vendor/lib – permissions 644) ***

Copies staged via Google Drive

Using X-plore or any suitable file manager

Files marked *** above already existed on my device so I renamed them to filename.lineage (filename as appropriate) to save them in case I needed to back out the changes.

Move files from Drive to relevant libraries and set relevant permissions as you go

Start Terminal session with following commands:

su

mount -o rw,remount /system

for each file execute

cd /system/… relevant libraries

chown root:root file (file as above)

finally

cd ~

mount -o ro,remount /system

exit

Restart device

After verification that DRM is working ok rename using X-plore:

In system/vendor/bin/hw

android.hardware.drm@1.0-service.widevine to android.hardware.drm@1.0-service.widevine.lineage

In system/vendor/etc/init

android.hardware.drm@1.0-service.widevine.rc to android.hardware.drm@1.0-service.widevine.rc.lineage

Hi there. I have little to no knowledge at all when it comes to doing this on my tablet. I'm a very casual user after all. I read all 28 pages of this thread. I was hoping if someone could post a very noob friendly step by step guide so I can avoid running into any issue as much as possible. I'm not really one to ask for spoonfeeding but I also do not want to end up with a brick. The first post did have a guide but I believe it requires knowledge on flashing roms which I currently do not have. If anyone has a kind soul that's willing to make a very noob friendly guide, I'd really appreciate it.

First thing is how to but into the Recovery and Download mode. This must you trainee.

Why ? If you have flash the TWRP with Odin than you must boot directly into the new Recovery, boot the Tab into System than you flash the TWRP again / it restores the Stock Recovery.

After flashing immediately reboot to recovery by holding POWER + HOME + VOL DOWN.

As soon as the screen goes blank change to VOL UP whilst still holding the other buttons.

If this done than can you flash the ROM.

Search on you tube how to flash xxxxx.

Hey there,

glad to see your efforts in getting DRM working. Recently my time was very limited, so I could not get a lot of new stuff done. I'll be gone for some time again, in the meantime you can check the current state of Android 10 here: https://sourceforge.net/projects/virsys-android/files/gt510wifi/crDroid/

There are some font issues in the launcher - the app names look a little bit weird sometimes and cameras are not working. DRM L3 worked on my device, Netflix launched and I could login without issues on the latest release. New version is crDroid as well, so a lineage-based derivative. It is, like you would expect from me, a work-in-progress. Even though I do have limited time to work on Android, it will probably not be the latest release. Security patch on this version is July 2020. Let me know whether you like crDroid or prefer "vanilla" LineageOS.
