Thanks jedld works perfectly. But been experincing some bug. But it works perfecly please make more update for this unofficial build. Its a great work.
is there any interest for newer builds?
I am starting a new personal project to use this TAB as car navigation and so working on LOS 14.1 based on the OP's sources anyways..
so I was wondering if there are still users out there using this good old boy? if so I would make a new thread for this ofc..

Hi, steadfasterX
I am also using SM-T285 as car navigation. I would love to see good GPS-able ROM for this!

ah good to know that I am not the only one
but I saw GPS fix isn't working yet , is that correct?
a bit offtopic I know but what app do you prefer for navigation in your country (which one is it)?
Hi steadfasterX,
I use the SM-T285 almost daily for various stuff and would love newer builds for this device! Especially, up-to-date security patches.
GPS works on my tab — time taken to get a lock if set to Device only can range from less than one second to about a minute.
Since one minute is too long, I installed UnifiedNlp as a system priv-app and various back-ends from F-Droid. Works great in my experience.
I have previously flashed Open GApps Stock with Jedld's Oct 2018 build — also works great and Google Maps consistently takes less than a second to resolve location if Wi-Fi is on. But I don't want my tablet to query ssl.google-analytics.com every minute so...
For navigation, I use OsmAnd~. Downloaded the map for New Zealand for offline use.

thanks for your replies guys. So I will create a thread when I have tested my current build.
If everything is going well, maybe this weekend already as I expect my tablet to be delivered tomorrow. I have to say that my Samsung times are a couple of years ago, so please be patient with me If something is not working as it should.
(already saw some weird stuff which needs to be done to fake the bootloader etc). Also have to say awesome job so far by @jedld ! He made my day with all his work he put into this device and ROM and I really appreciate to see all needed sources etc which is often not the case .. So: a heavy thanks dude!
Due to the fact that the last build is from long time ago I nevertheless needed to clean and re-settle several parts of the sources and i want to integrate TWRP builds as well.. But one step after the other
Sent from my OnePlus 6T using XDA Labs
I'm excited! Will be looking forward to the new builds!
Jedld did an awesome job with this tab! Many thanks to him
This may put off some users though as camera does not work fully on the LOS 14.1 builds. Open Camera and video calls on Signal work, but the stock app, even Google Camera and other apps that use the camera (e.g. barcode scanners, FreeOTP) fail. Also, video recording will fail even in Open Camera. Maybe something to do with missing libs or the Camera2 API? Otherwise, the build is as perfect as it gets.
On the other hand, if the goal is simply navigation, then the camera may not be needed, unless one absolutely must navigate while simultaneously using the device as a dashboard camera (e.g. using multi-window)
As for TWRP, I am using the one from Jedld's OmniROM build (title below, can't post links yet sorry). Device decryption works, formats partitions to ext4. Previously used it to flash Open GApps successfully.

Cool! Would your TWRP build be able to format partitions to F2FS?
maybe in a later build yes. the ROM (kernel and system) must support that as well then so first of all I want a general working release

Nice!
****.....
the moment when you open the package and find 2 Tablets and both are SM-T280 instead of SM-T285... damn..
tbh I didn't realized it until I flashed TWRP and it didn't booted whatever I tried..
then I realized it shows SM-T280 in download mode.. wth.. and yea I ordered SM-T285..
I hope to get it exchanged asap..

Sorry to hear that. Look out for the presence of an earpiece in the coming tablets (although I find it rather ridiculous to hold up such a big device to your ear)
The seller hopefully will accept back tablets with TWRP installed?
Unless of course you removed TWRP and installed back the original recovery (I couldn't somehow find the original recovery and stock images for this device from the Samsung website)

Another SM-T285 user. Glad to hear of your ROM-building plan. Thanks very much for the effort and hope you're able to get the correct device to hand.
I am currently downloading the stock ROM from https://sfirmware.com which has pretty fast speed and then will try to set the tablet back to its original state.
JOdin still works great on linux btw..

I still use this device for navigation. Stock 5.1.1
Would be realy nice to have an newer Android version available...
iGO Navigation (main app), TomtTom NDS and Sygic Truck (both for testing)

good to know. seems it was a good choice of mine to buy it.. it has the perfect dimensions for me, can be unlocked and thx to jedld the most of the work is done for using LOS in the way I need it..
today I have sent the wrong delivered SM-T280 back (I will get a full refund but wouldn't had accepted anything else).
on sunday I bought 2 used ones (with photo proofs of the real devices) and hope they will arrive this week.
(acc to your sig) you're still on stock for your LG G4...... ??

Yes, Stock LG 4
@SM-T285
Same decision for this device. Size ist perfect - mainly used in portrait modus - and accu can powered up while driving. For bigger one it's very difficult to find a car charger whicht really charge the device.
LTE do it's job - also for Roming.
Stock 5.1.1 is fine and all works, but think newer Navigation apps will use newer android versions...

Glad to know where I can get the stock ROM. Thanks
I have been using heimdall on Linux (terminal only
), but will definitely look into JOdinSimilar threads

40This is a port of LineageOS 14.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. LineageOS needs no introduction, it essentially a rename from CyanogenMod due to naming issues.
5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.
I don't recommend you use this as a daily driver, but it should be good enough for some. Make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom.
Based off on LineageOS 14.1 sources which is based on Nougat 7.1.2

As usual hit the download section for both the newest and oldest builds. This build also uses an experimental kernel under the performance_2 branch:
https://github.com/jedld/kernel_samsung_gtexslte/tree/performance_2
This build is still alpha so there might still be issues.

Update Feb 12, 2017
===============
- really fix mtp and usb connectivity
- There is a bug where pattern unlock won't show up even when you swipe up in the lockscreen. As a workaround make sure you select "Directly show pattern view" in the "pattern unlock settings" page (Click on the settings knob besides the Screen Lock option). If you somehow forget to do this, you can click on a notification to force pattern unlock to show up, if you don't have notifications, connect your device to USB and the charing notification should show up.
Update Feb 11, 2017
===============
- Improved graphics, HW composer, gralloc built from source and updated Mali drivers
- F2FS support for data partition
Update Jan 31, 2017
===============
Bundled with the new perf+ kernel that I am using for the CM-13 buids
Works:
- Wifi/SMS
- Mobile Data (Need to restart once after first boot)
- Audio
- Graphics
- Incoming/Outgoing Calls
- MTP
- Camera (Stills capture works with 3rd party apps)
- Bluetooth
- Wifi Hotspot
Does not work:
- video recording (sometimes works with 3rd party apps like open camera)
- GPS (no fix)
Issues
* Stability issues and some boot loops (Try to disable hardware GPS, or location services which may solve it)
* Wifi and network performance issues when both bluetooth and wifi is on and vice versa (needs confirmation from testers). I'm not sure if this problem also happens under stock. So if someone can give me feedback that would be appreciated.
* Setting alarms using the stock clock app will crash your tablet, use third party apps instead (this is a bug in upstream LineageOS and not related to this device)
Not essential but still needs to worked on
- HW encoders(06/26/2017 hw decoders now supported)
Other Notes:
- selinux permissive
Most of the issues are fixable, I just need more time and encouragement
SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.
Download
========
Remember flashing an unofficial ROM on your samsung device will probably void your warranty, Samsung representatives will probably not be able to help you as they are still stuck at 5.1.1 land as of now and have no idea how to handle a SM-T285 that is running 7.1.
As always flash this at your own risk. Make sure you have a copy of the stock ROM so that you have something to fall back to, which is highly the case when using an experimental rom.
See DevDB download section. Or get the latest version LINEAGE-OMS-14.1-20181117-UNOFFICIAL-SMT285-ALPHA.zip
For Older Versions/OMS builds see downloads sections:
All Downloads
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-7.1-nano-20161109.zip)
Installation Instructions
==================
Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.
Download the zip file and extract the tar.
Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock or another rom make sure you wipe first using TWRP. DO NOT USE twrp to flash these zip files, they are not configured for that.
Root and customization/ Build Guide
===================
LineageOS unlike Cyanogenmod does not come with root. However you can easily root it by using TWRP to install the latest version of SuperSU.
If you want to customize this ROM and/or repackage it you may use this guide as a reference.

Also happened to me. What I did was to rewipe after Gapps and it worked OK after that. Also set GPS to power saving4
Just uploaded a new build. The lock screen issue is still there though, but it should be tolerable with the workaround that I suggested.
