All my public builds work fine for me, but I don't use gapps, magisk or any other things like that.

For others, depending on what you do and the expectations, maybe not. As I wrote in my FAQs, try it. If you don't like, then don't use it. You can also read the comments and feedback in each 19.1 and 20 thread to see what others are saying using my builds.

In case you didn't see this, Google no longer makes Android 11 security patches as of March 2024.

https://source.android.com/docs/security/bulletin/2024-03-01

This has led LineageOS to discontinue 18.1 on March 5, 2024 as per

https://lineageos.org/Sunsetting-LineageOS-18.1/

However, Markus S, who is already doing the 16.0 security backports, posted 18.1 UNOFFICIAL patches yesterday at

https://review.lineageos.org/q/topic:"R_asb_2024-03"

Thanks to Markus, we have the UNOFFICIAL March 5 security patches.

New build called lineage-18.1-20240311-UNOFFICIAL-gt510wifi.zip

NOTE: All builds that I upload have been personally tested on my 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.

Thank you for your system package, but when I use twrp, I always prompt error 1. I don't know what the problem is. Zip is the same as my device model, and the version of twrp is also corresponding.

@bierma32 , any chance you are using Mindthegapps? @Schaagi had some slowdown problems with this 18.1 rom and mindthegapps. He then switched to opengapps PICO and said that performance was on par with 17.1 + opengapps. He initially used mindthegapps because openagpps wasn't available for Android 11 yet.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] bierma32:
Yes, i am using MindGapps, will try a next clean install without Gapps and will install all Apk from APKpure to see if it makes difference.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
@bierma32 , it's way safer to use Aurora Store as it's open source and it gets the exact same apps from playstore. This is assuming you don't have any paid apps. Or if you have paid apps, try opengapps.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] UPHE21:
I have upgraded twrp to the latest version, but it still shows the error as before: 1. Is this related to the official rom, or is it related to the region? My official rom Android version is 6.0.1. Does this have any impact? Thank you.

Sept 9 release notes

1. Reverted the patch to https://github.com/retiredtab/andro...mmit/a32c7a0bed536281d20b7c1cf8d41c84a268cc80

Removing systemUI from pinner services causes a 4 to 6 delay in bringing up the home screen. This is seen when loading or playing a game for about 20 minutes and then either hitting the recents or home button. By reverting this commit, pressing recents or home button brings up the systemUI right away.

2. Sept 5 security patches as per https://review.lineageos.org/c/LineageOS/android/+/315661

@sheinbo, I use and recommend TWRP 3.5.2_9-0. I have had no problems with my P550 using TWRP to backup my 17.1 and 18.1 files and switch back and forth. I have never had it go into Download mode after a restore.

I suggest you backup your TWRP directories onto a PC or microsd card and then do a complete wipe of everything and format data. After formatting data, put your TWRP directories back onto the Internal Storage and try to restore your data again. If that fails, there's something likely corrupt with the 18.1 backup then and you will have to delete that backup and start over from fresh again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
I had that happen to my TWRP settings once where it got corrupted, but that was on a different device (SM-T710). Since the TWRP settings were corrupt, I couldnt' get adb working again. It was only when I formatted data and then TWRP adb worked again.

When making these ROMs, I EASILY use TWRP more than 100 times to flash, erase, backup and restore.

One thing I heard is to never install the TWRP app as it may cause problems. For TWRPs that I build like the P550, I exclude that option so the enduser never even sees it. I built the TWRP P550 because no one else has.

Once you get TWRP installed in the recovery partition - upgrading this thing is a breeze with an SD card installed. Made the jump from v17 to this latest v18 - with no issues.

@retiredtab- If you need beta testers for v19 whenever that happens - I'd certainly be willing (SM-T550).

Thanks again!

Hi. Is the camera the only thing that separates this from the official one? I currently have the LineageOS 16 for t550 and I want to know if this is better in terms of stability and performance compared to the Unofficial 16 LOS here in the forums. And is MicroG supported?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] buggydummy:
Can't believe no one has found this bug yet. I have the official Samsung Book Cover case installed. Whenever I would close it, the screen doesn't lock. The thing is, the screen locks and turns off display when I close the flip case on LineageOS 16 so it's kinda weird that it doesn't work here
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Uluru25:
Not a problem for me, display off works as expected.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
It works fine for me. When I close the cover and open it, the screen lock appears and I get prompted to enter my PIN.

If you dirty flashed from 16.0 to 18.1, you can expect weird unexplained problems. This is documented in FAQ 11.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] buggydummy:
It seems my flipcase wasn't being detected before. Now the smart cover is being detected fine. Sorry for the false alarm.

While I'm at it, when you release the next update, is a clean install still necessary or can I just dirty install the next update through twrp without having to format anything?

Till now dirty flashing worked well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
16.0 ==> 17.1 = clean install/flash required

16.0 ==> 18.1 = clean install/flash required

17.1 ==> 18.1 = clean install/flash required

18.1 ==> 18.1 = clean install/flash required IF you come from another rom like crDroid 18.1 to LineageOS 18.1

18.1 ==> 18.1 = dirty install/flash is generally okay IF you come from the same ROM and builder (i.e. LineageOS to LineageOS built by me). For example, if you flash my Nov 2021 build, you can dirty install/flash the Dec 2021 build usually with no problems. However, depending on the apps you load, sometimes a 18.1 to 18.1 dirty flash will not boot or work.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] buggydummy:
@Uluru25 @retiredtab

Appreciate the responses you made and how you explained them. So to my undersranding, I can just install the Dec zip? No extra steps to do beforehand? Basically put the zip on the sd card again then install using twrp? None of the partitions have to be formatted? Even the cache?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Yes to the above.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] toybits:
@retiredtab First of all thanks so much for your hardwork and this ROM. One thing that I noticed that widevine seems not working on this rom. I install DRM Info and it does not show any widevine L3 or L1. So some apps that require video does not work. Just wanted to confirm if widevine does not really work or am I just missing it? Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
@toybits, I use devcheck by flar2 to check for DRM and it shows L3. I have used drminfo by android fung (which also shows l3) in the past, but devcheck is ad-free and comes with other handy utilities, tests and information.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
In addition, widevine L1 is highly unlikely/never on these custom rom devices due to the closed source software, proprietary libraries, certification process, etc. If you need L1, stick with stock rom.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] toybits:
Thanks so much. I re-flashed it and everything is working as it should. L3 showing and apps working. I feel this last update is much more faster. Thanks again for keeping our tablet up to date! 😁
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Weird, something must have gotten corrupted on your flash file system if a simple re-flash fixed the problem. Normally /system is a read-only file system when the OS is loaded. If you have root enabled, you can remount /system as read-write though.

I have done nothing to the T550 source code for the Nov 5th patches that would make it any faster.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
It doesn't and I have no plans to make it work with OTA and build the infrastructure to support it and deal with the headaches and problems that come with it.

Dumb question - what would be required to port this to LineageOS directly and have them take care of the OTA side of things in an official capacity?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] zRetix:
Just flashed this evening, no major problems, seems to work great. Android Layout seems like Phone Layout not Tablet ? And just out of curiosity: Is there a LineageOS 19 Version planned ? And I used the newest TWRP version(twrp-3.6.0_9-0-gt510wifi) and not the recommended, might this lead to problems later on?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
To expand on FAQ 18, getting "official" status means meeting every checkmark in the charter below.

https://github.com/LineageOS/charter

and

https://github.com/LineageOS/charter/blob/master/device-support-requirements.md

All msm8916 builds that I have made for 18.1 overclock the CPU and GPU which violates the kernel section. That's just one example. The overlock CPU and GPU is in the msm8916 code repository by default. There's a bunch more work that needs to be done and I'm not willing to put in the time to meet those requirements just for OTA.

Then's there the expectation of "support" for "official" builds. Right now, as you can see in this thread, there's posts that show

no effort/low effort

clear evidence they didn't even bother to read the FAQ

can't follow simple instructions written in the FAQ

As such, I never reply to those posts. If my roms were official, I might be expected to answer such posts which completely wastes my time and makes me wonder why I should continue to make 18.1 or work on 19.0.

BTW, OTA can work without "official" status. I have a Samsung N5120 and it's developer has his own OTA server, but it's slow. It takes 45 minutes to get an OTA update. I can download the same 500MB file from a server in less than 2 minutes.

So again, I have no plans to offer OTA because I don't want the headaches and complaints associated with it.
