• 2017-10-23: Update to current cm-13 including fixes to avoid WPA2 KRACK for p6800, p6810, i815.
• 2017-09-12: Finally, I managed to compile a version for i815 but telephony/mobile data does not work
• 2017-08-23: Stabilized the new Browser, alias Gello - it formerly crashed, e.g. when opening our XDA page; Deactivated bluetooth again, since it is not done and crashed. It is still a long way: I assume I have to adopt the current Lineageos bluetooth app like Daniel did before: https://github.com/danielhk/android_packages_apps_Bluetooth. Daniels is outdated, unfortunately, cannot be used right away.
• 2017-07-27: Optimizations ZRAM, ISM and read_ahead also for P6810. Tried to activate bluetooth following danielhks guide. Succeeded with 3.1 in the guide - testing on command line. But in ROM it crashes when I try to activate BT via Settings.
• 2017-07-24: Video streaming and playback fixed with help from Bauner - native media codecs work now - meaning Youtube in preinstalled browser works now and also playing local mp4 files. I found that some optimizations (e.g. ZRAM) are not yet applied in P6810, because of a separate init.rc (-wifi) -> will be fixed in next release
• 2017-07-15: Auto-rotation fixed! And GPS works again, too. (got lost again in last build)
• 2017-07-13: Changed default orientation to Portrait. Deactivated DRM again on P6800, since mediaserver crashed in libwvdrmengine.so - and by that Youtube also broke in playing - now Youtube runs fine, but Play Movies does still not. On P6810 hopefully both works (Could not find a difference yet). Still the rotation issue is there, not from the beginning but during usage the orientation freezes somewhen...
• 2017-07-10: Further speed improvements, deactivating swipe in AOSP keyboard, what crashed
• 2017-07-09: GPS fixed, thanks to p3dboard - I was able to add a NON_PIE_SUPPORT
• 2017-07-07: Add several tweaks for memory usage and disk r/w speed, changed dpi to 202
• 2017-06-28: first release

• 
  Download the ROM and optionally GApps (ARM-6.0-pico) onto your device

• 
  Reboot tablet into TWRP recovery. I use version 3.0.2-0 here.

• 
  Wipe data, cache, dalvik/art-cache and system. Coming from stock rom, also wipe internal sd.

• 
  Flash ROM and GApps.

• 
  Reboot System. (First boot takes 5-6 minutes. Be patient.)

• 
  Bluetooth - crash when activating via Settings

• 
  DRM playback (google play movies) crashes. But after the crash starts playing on P6810!?! Currently, playback on P6810 is not smooth anymore, caused by the new codecs setup. Will investigate further.

• 
  Recent Amazon Kindle app crashes -> use an older one 4.24.0.27 or just delete libunwind.so in /data/app/...kindle directory

• 
  Internal mount of sd-card does not work -> use portable mode

Just flashed it on my P6810, its feeling quite smooth. So far apart from the bugs noted above, I noticed that the Recent Apps view isn't showing a little image of the application, but that's not a major issue, you can still see the applications to swap between via the title bar it shows.

I've attached the Widevine L3 files from the cm13 repository link, from the Muppets github, if we replace the ones in your current build with these, that should fix the DRM playback

Edit: I just tested Google Play Movies with the existing Widevine L3 files in your build, and the Flash Season 3 played fine, the film Independance Day also played fine, so I think your Rom is fine as far as DRM playback goes.

Edit: Removed the .ZIP file, as that wasn't actually the .SO files, but html files (so if anyone downloaded the .ZIP - don't use those files). Anyway, it looks like it isn't needed
Edit: Re-uploaded ZIP with the real .SO files - Just incase you need them for testing.

Hi Frank,

Your line for the libdrmdecrypt.so was sending it to the /system/lib folder, it should go to /system/vendor/lib, and I don't think the libMc* files are needed as you say, as I have never needed them before. I've attached a flashable version of the Widevine L3 blobs for CM13, which works fine on my p6810.

so your code should read as

Code:

# drm blobs
PRODUCT_COPY_FILES += \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/libdrmdecrypt.so:system/vendor/lib/libdrmdecrypt.so \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/libwvm.so:system/vendor/lib/libwvm.so \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/drm/libdrmwvmplugin.so:system/vendor/lib/drm/libdrmwvmplugin.so \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/libwvdrm_L3.so:system/vendor/lib/libwvdrm_L3.so \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/libWVStreamControlAPI_L3.so:system/vendor/lib/libWVStreamControlAPI_L3.so \
    vendor/samsung/smdk4210-tab/props/system/vendor/lib/mediadrm/libwvdrmengine.so:system/vendor/lib/mediadrm/libwvdrmengine.so \

Regards,

Peter

Hi Frank,

I also have those free movies, big and blank, and on my P6810 they play fine. Your original Widevine L3 blobs in your p6810 rom also worked fine for me under LineageOS 13, so I think your original files were fine.

I can see from my original Slim Rom build notes, that I had put libdrmdecrypt.so in the /system/lib folder, so I think it can work from either location.

Did you try just flashing the flashable version of the Blob's I attached in the previous post after flashing your Rom? It would be interesting to see if that makes any difference, it sets the permissions on the blob files as well to 644, which they need to be to work.

There's an app called "DRM Info" that I use from the play store to confirm that it can load the Widevine DRM libraries fine.

What changes do you make between the two Rom builds (for P6810 and P6800)?

Is it just this change?

Code:

FILE: /device/samsung/smdk4210-tab/device.mk
# **************************************
# * modify file and add these contents *
# **************************************
#adjust to wifi only for p6810 - modify according to device type, p6800, i815 - same as CM 12.1 build format - check CM 12.1 library for references

# common_full_tablet_wifionly.mk - p6810
# common_full_tablet_lte.mk - p6800

Btw, I believe (but haven't tested it), that you can flash the p6810 rom on a p6800 (but you won't have Mobile Data support), and you can probably test to see if the Google Play movies works over Wifi with your p6810 build, as the original build you made for me works without the updated Widevine L3 package.

Edit: Just looked over Daniels Repository - https://github.com/danielhk/proprie...10/tree/cm-13.0/smdk4210-tab/props/system/lib

Looks like he has two files in the /system/lib, libdrmdecrypt.so and libwvm.so - so change the code to update these two files, as it could be that you have a duplicate file, one old and one new, and this is causing the issue.

I just tried the gps on my p6810 and see its not working. It's probably because the non-pie blob support hasn't been enabled in the linker library as the gps blob/driver is old and needs this enabled.

Frank, there's notes in my slim rom compile notes on how to do this in linker.cpp from memory, the line numbers will probably be slightly different, but the code additions should help you locate the bits that need updating.

Just read this thread and start play again
My P6800 flash rom with Pico Gapp but seems running not smooth and found out some common issues:
- flash SuperSU 2.82 zip through TWRP successful but not get rooted can not use Kernel app.
- play YouTube: all have stopped with black screen just few seconds after running then replay. All clips get same problem.
Have no idea but seems it needs fix more.
One more thing the brightness of screen very low even manual with brightness maximum.

Hi, thanks for testing!
1. Right, install SuperSU-V2.52 and then try to update and finally update binary. The last step takes a while but always returned on my device, with success or unsuccessful - trying again after reboot it finally succeeded
2. Yes, this and the screenshots in app-drawer are missing - this is intended by the "LOW_RAM" configuration I set (https://source.android.com/devices/tech/config/low-ram)
3. I will upload a new version with fixed auto-rotation soon - still, the picture change comes with a black screen sometimes
4. Have to check the youtube in browser issue - this sounds more serious. Do you have a P6800 or P6810? Could you check the youtube app? This should play fine - and will even rotate on next version
5. Sure, had no time yet to implement ( a guide how to is there by p3dboard)
