Cool, thank for making rom for old device. may I ask, in the first post last update 29-04 but when I see it in the link you included there are only 03-04? and where can I find .tar build?

New build arrived for discoveryOS (diOS)

The very first fully customized build for GPS navigation!

Re-branded completely to "discoveryOS (diOS)"!

Due to the re-branding the OP has been fully re-worked to reflect all changes of this project.

Changelog

Release date: 2020-05-08

Download: see OP

Kernel:

nothing

diOS:

initial release just for diOS!

This includes:

- custom boot animation

- custom default wallpaper

- custom build id

- added Automate app

- added F-Droid

- added Waze App

- and much more..

CHECK OUT THE OP FOR INSTALLATION INSTRUCTIONS!

A CLEAN FLASH, INCLUDING FACTORY RESET IS REQUIRED!

The new included Automate app is missing the navigation flow to be fully operational (will be fixed in the future).

The flow can be downloaded here: Kioskmode Flow (kioskmode_discoveryos.flo)

Download the flow to the device and open it in the file explorer. You get prompted to import the flow. Click start and the flow will enable a light version of a kiosk mode for the app "Waze".

Detailed changes:

LOS: this build VS. last build (nothing as I need to settle up the split of LOS and diOS, so still on 2020-03 security patch level etc)

Device tree: github

Kernel: github

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] myLittleBuns:
Thank you for this ROM! Really appreciate the latest security patches being available on the device.

For now, I needed the basic services, so I decided to install LOS. May get around to installing diOS later. Did so by performing a dirty flash of the latest LOS zip file from the leech server—lineage-14.1-20200403-UNOFFICIAL-gtexslte.zip—using TWRP, with Jedld's kernel and system files present. Successful. Only caveat is that the external storage was not found in the first boot. Did a reboot and the tablet successfully found my files and 60+ apps on the external storage.

Next, I found that NetworkLocation.apk from UnifiedNlp was removed from /system/priv-app directory, so I re-installed that using ADB. Successful. Another caveat, as already mentioned in OP as of the time of writing this, is that there really is no auth required for ADB. On the other hand, `adb root` would not work if Root Access is disabled in the Developer Options.

Tested some aspects of my device:

Calls and messages work perfectly

Mobile data and Wi-Fi connect quickly (contrasting to what one poster said)

Full disk encryption is fully supported

Alarm clock functions work without crashing the device (one of Jedld's ROM did otherwise)

GNSS performance is the same as before—does not make the fastest connection in the world, at least in my area, but it does its job and precisely too

Aeroplane mode really does work on the SM-T285 (on the other hand, the Pie ROMs on the Galaxy S III Intl. suck up battery in Aeroplane mode, showing a red bar for Mobile network signal in Settings>>Battery)

OpenCamera works almost perfectly (contrasting to what another poster said)—video recording does not work

Apps2SD works perfectly

Bluetooth connects, but there is no Bluetooth audio, and key strokes from my Bluetooth keyboard register slowly. Sad that I cannot already use this device to connect to loudspeakers and for SSH purposes.

Lockscreen rotates (contrasting to what another poster said). One minor quirk: locking the screen temporarily puts the screen upside down during the animation to dark.

Hope this post is useful to anyone wanting to use LOS (e.g. need the basic services, especially during this health crisis). Perhaps, the above also applies to diOS.

Excellent work, congratulations !!!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Sarolmonay:
Can you fix, video recording? Even video call in messenger can't..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] myLittleBuns:
Video call in WhatsApp and Zoom does not work too, in this ROM and in Jedld's LOS ROM (tested the APKs from their respective websites). QR code readers and FreeOTP scanning do not work too (had to manually input the secret keys for the few websites that even show them). On the other hand, video call works flawlessly using Signal Private Messenger (tested the F-Droid version).

Maybe this has something to do with some missing API? Apps that do use the camera successfully may use a lower-level API/lib, whereas a higher-level API/lib may not be present in the system/kernel so that other apps cannot utilise the camera functionality. I have not much experience in Android to know if this is correct or not.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sagalescarlo:
Nice Custom Rom. But anyway to remove Waze and Automate? I cant get them deleted in System/app. Btw im using SkyHawk Recovery

And Please fix screen glitches. Sometimes when im using facebook random screen glitches occurs. Like Screen Shaking and Screen Tearing. And please add a landscape rotation when in lockscreen.

But Nice Rom Man. Im gonna use this as a pernament OS since the tablet is stuck at 5.1.1.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] steadfasterX:
You have to delete them in system/app and clean dalvik cache and format cache in TWRP / SHRP .

Thanks steadfasterX

This ROM works well on my T285.

I have not tried Bluetooth yet.

I did not install gapps.

Open Camera worked!

One issue I found is I couldn't find a QR code application that will work with this ROM.

One great thing about this ROM is I don't have to use ODIN to install.

I used TWRP to install. Rooted with Lieneage addsu.

myLittleBuns post was very helpful and i installed the same - "lineage-14.1-20200403-UNOFFICIAL-gtexslte.zip"

Hope you can find a way to make QR scan work. If no solution, then I will use this just as an Android 7.1 tablet. I will scan with another Android phone.

Thanks

Quite ok rom. Keep forwarding.

I have installed it yesterday.

Gapps from 2017 works.

MagiskSU and MagiskHide works flawlessly that i can install Netflix from Play Store.

Camera works with third-party apps (like Hedgecam 2 or OpenCamera, recording video works with poor quality.), but in other app it doesn't.

Sometimes the screen flashes, especially Magisk Manager or youtube vanced app.

App2SD or second partition does not work, Link2SD says invalid argument. But anyway i found some workaround so it's ok.

Overall this rom works fine, but you need to improve it to use on daily usage. I hope someday the camera bug will be fixed, so that you don't need another camcorder to record (if you use as navigation tracker)

And sdcardfs limitations tho to download large apps. Honestly i'm use this tablet on my daily use ( like watching youtube, playing games, texting, etc..) and i wait a rom to flash since last year because stock rom isn't really good.

"Simple Camera - Capture photos & videos easily". It can be downloaded from the play store and has an orange icon, unfortunately I cannot place the link here.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] steadfasterX:
Fix is coming soon..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] steadfasterX:
Announcement

I will likely completely discontinue LineageOS builds.

The reason is that I really do not like Google spyware and so already switched over for all my other devices to /e/ OS instead.

/e/ OS is based on LOS but all google spyware has been removed + it contains microG out-of-the-box which helps in running services and apps which require google APIs.

That means:

likely no newer LOS builds

The base of discovery OS (diOS) will be moved to /e/ instead of LOS

pure /e/ OS build has been released already here: https://xdaforums.com/galaxy-tab-a/development/rom-e-os-samsung-galaxy-tab-7-0-lte-t4191783

that build contains a fix for the bluetooth issue we have in the latest LOS build.

a new discoveryOS release will happen soon which then will be based on eOS instead of LOS.

Just curious, which "tab A" since there are so many varients.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] steadfasterX:
New build arrived for discoveryOS (diOS) 2.0 - the first time based on /e/ OS

Changelog

Release date: 2020-11-19

Download: see OP

WARNING: Due to the fact of all the listed major changes a full clean flash is

required!

(i.e. factory reset, wipe system!!!, cache and dalvik cache)

As you might noticed I have completely re-worked the OP (and title) to reflect better what diOS is. Take a minute and review it to find out if that ROM is for you or not.

This one is really a major upgrade: diOS 14.1 was based on LOS 14.1 and this new diOS 2.0 build is based on /e/ OS instead. Read the OP for all the details! This changes everything you might expect from a standard Android custom ROM as no gApps are needed (and

possible

!!) anymore.

Changed version numbering. When based on LOS 14.1 it was just that: 14.1 but now as diOS is grown up and also using a different base I decided to start from the beginning. Why 2.0 and not 1.0? I feel the previous LOS based variant as a 1.0 and so as a logical consequence we go with 2.0 with this major upgrade.

Introducing OTA update support. From

next

build on it will be possible to use the internal Updater in the Android settings menu for a convenient update experience.

Bluetooth fixed (that is why I needed to go to selinux=permissive from now on - I might not go back to enforcing as for the diOS usecase it does not matter that much - imho)

Platform Security Patch: 2020-09-05 (yea I know that /e/ is late on that one)

/e/ base: gitlab

Device tree: github

Kernel: github

Vendor: diOS

Known issues:

The new included Automate app is missing the navigation flow to be fully operational (will be fixed in the future).

The flow can be downloaded here: Kioskmode Flow (once started it re-opens a Navigation app when closed/pushed to background)

Download the flow to the device and open it in the file explorer. You get prompted to import the flow. Click start and the flow will enable a light version of a kiosk mode for the app "MagicEarth/Maps". If you want to use any other navigation app just edit the flow accordingly.

Exactly the same problem on diOS based on / e /. Even during the first launch of the system, Aurora takes off. F-Droid cannot install any program. The browser works fine, downloads everything, but when you try to install apk (after downloading the installer, and clicking the "install" button), an error occurs that "the package installation service has been stopped. Otherwise, the firmware seems to work fine, although it looks very Specific. Will there be support for themes for the system? Or support for substratum? Unfortunately, I cannot send the log, because I had to rollback to LOS. write that everything "works great?" Perhaps I need another recovery for the firmware? I used TWRP. Thanks in advance, and thanks for the hard work on developing the firmware.

As you can see a total of 7440 MB (rounded! that's why it differs by 16 MB from reality)

the internal storage (what your file browser is saying) is "/dev/block/mmcblk0p27" which is 5036 MB (Bytes: 5280628736) - which is exactly like that: 4.9 GB -> plus formatting a partition always eats up some disk space so 4.8 GB sounds perfectly fine.
