[UNOFFICIAL][ROM]ALPHA LineageOS 19.1 for SM-T710 - Sept 16, 2023

[lpedia]

New build called lineage-19.1-20230213-UNOFFICIAL-gts28wifi.zip

For those who use or want to use gapps: I found that NikGapps-core-arm64-12.1-20220709-signed.zip continues to work well with this ROM on my device. I have not been able to get a later version to work correctly with it. Although it would appear to install correctly, on reboot there'd be no Play Store.

Note that if you're dirty-flashing an update on top of existing NikGapps, you will need to reflash NikGapps just after flashing the ROM. I do not know if this applies to other gapps packages as well.

The fix is working well, my tablet is noticeably cooler and I can see it at 400Mhz often

In my case too, now I can use my tablet without burning my fingers lol

Any chance this can be ported to T713?

Curiously, my T710 was very well behaved with the January update, but after dirty flashing the Feb update I started having random reboots, occasional overheating, and the "cannot provide internet" problem. The three problems seem correlated, and usually disappeared after a restart or a power+home+vol down reset. Should I return to stock and flash the Feb update, or wait until the March update (and then should I return to stock before flashing)?

I'd suggest clean-flashing the Feb update and see if that behaves. No need to go right back to stock.

Dirty-flashing updates usually works, but as a general rule try a clean flash if there are any glitches.

Could you please point me to instructions for clean flashing from twrp? Thanks.

@Dr_MC - this is how I'd do a clean flash with TWRP:

1. In TWRP, select Wipe > Advanced Wipe.
2. Tick Dalvik / ART Cache, Data, Cache, System, then swipe Swipe to Wipe.
3. Touch the Back button and select Format Data. Type yes when prompted.
4. Touch the Home button and select Install.
5. Select the ROM zip and any addons (such as gapps), then swipe Swipe to confirm flash.

https://forum.xda-developers.com/t/...know-before-toying-with-your-android.4286651/ is a good introduction to XDA terminology and processes like clean and dirty flashing.

NOTE: lpedia has built the rom and pflyaz personally tested the build on his device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.

Just wondering if anyone's been having issues with instagram. I started using it again, tried deleting and reinstalling the app but eventually the feed is a few days behind and images refuse to load. I haven't seen this issue happen on any other device but this S2. Can grab some logs later. Also videos are extremely low quality on instagram too. I only found 1 other person who commented the same but on lineage 18

I don't use Instagram and never will so I don't know why your feed is late or refuses to load.

For Instagram and low quality videos, I only know this because @ananjaser1211 mentioned this to me sometime in past year or two?

This commit

https://github.com/universal5433/pr...mmit/10a2ac9ff23a0a2c589df5c4ba1c21e4fd539d91

says it fixes

"This fixes Apps that rely on encoder (Live message and many others)
And fixes quality (decoder) in apps like instagram , twitter and so on"

Later on, the blobs were updated again in this commit.

https://github.com/universal5433/pr...mmit/c105d6037c7ad74a030101a946a53a2faf587e3d

* Previous OMX was "too new" and had many unsupported formats
* Also its AVC.Encoder is not supported on our phone
* This OMX solves all those issues
* Apply patch

sed -i "s|system/lib|vendor/lib|g" $BLOB_ROOT/vendor/lib/libExynosOMX_Core.so

So download these 2 files

https://github.com/universal5433/pr...m/vendor/lib/omx/libOMX.Exynos.AVC.Decoder.so
https://github.com/universal5433/pr...m/vendor/lib/omx/libOMX.Exynos.AVC.Encoder.so

$ sha256sum libOMX*
8de9c97fcf6af9f5e96e93bd9be1d54b1a19180571129f4535b8384d3b5a6358  libOMX.Exynos.AVC.Decoder.so
622f23a8dc367d0b2296bd2337c7ef2e3d87241f7ec3479ab22f9e6296441e5c  libOMX.Exynos.AVC.Encoder.so

$ ls -al libOMX*
-rw-rw-r-- 1 l l 237496 Mar 28 16:42 libOMX.Exynos.AVC.Decoder.so
-rw-rw-r-- 1 l l 245704 Mar 28 16:42 libOMX.Exynos.AVC.Encoder.so

On my existing 19.1 build, I see

gts210wifi:/system # ls -al ./lib/omx/libOMX*                                                                                                             
-rw-r--r-- 1 root root 164044 2008-12-31 17:00 ./lib/omx/libOMX.Exynos.AVC.Decoder.so
-rw-r--r-- 1 root root 169744 2008-12-31 17:00 ./lib/omx/libOMX.Exynos.AVC.Encoder.so

so they are earlier versions.

To update, follow these steps and see if Instagram video playback is better.

UPDATED/EDIT: See post #94 instead.

1. Save your device data.
2. Download newer versions of the libOMX encoder/decoder onto your PC.
3. Boot into TWRP.
4. Touch mount system
5. # cd into the directory where you downloaded the 2 files
6. adb push libOMX.Exynos.AVC.Decoder.so /system/lib/omx
7. adb push libOMX.Exynos.AVC.Encoder.so /system/lib/omx
8. # verify file sizes are correct
9. adb shell ls -al /system/lib/omx
10. reboot into OS and test Instagram

I only found 1 other person who commented the same but on lineage 18

I have no idea if that person is running my 18.1 rom or another.

The above post changing of the OMX breaks stock camera video recording. Anan suggested something else which I will post in the next thread once I test it out.

 

[retiredtab]

@ananjaser1211 suggested that the low quality video is due to the open source OMX drivers not supporting adaptive-playback. He suggested removing all instances of that parameter from the media_codecs.xml file which I have done and attached as zip.

@zed011, try this

1. Save your device data.
2. Download media_codecs.zip and unzip it.
3. Boot into TWRP.
4. Touch mount system
5. # cd into the directory where you downloaded the file.
6. adb push media_codecs.xml /system/vendor/etc/media_codecs.xml
7. reboot into OS and test Instagram

I tried the file, looks like now videos aren't playing at all for instagram, reddit and youtube. Here's a log I captured for youtube.

I tried a few things but couldn't pass safety net. Is there a way to do it? Not really important because I won't use banking apps on such an old device anyway. The rom is superb. Feels like a completely new device.

I changed the device fingerprint with magisk hide props and tried universal safety net fix.zip
