[ROM][UNOFFICIAL][7.1.1][TEST] OmniRom for Galaxy Tab A 7 LTE (SM-T285)

[jedld]

This is a port of OMNIRom 7.1.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. OMNIRom aims to be a community based project and is a lot "lighter" than CyanogenMod/LineageOS.

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 I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out.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.

Though this is stable enough that I use it currently as my daily driver, make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom. This rom probably won't get much use out of some people until bluetooth is fixed.

Based off on OMNIRom 7.1.1 N4F260 sources which is based on Marshmallow.

For more information on OMNIRom and its features see their site here.

Omnirom Notes:
=============

- omnirom doesn't have ffmpeg libraries unlike the CM based roms, but no worries since I ported over CMs libraries here.

Works:

- Wifi/LTE/SMS (Some users report data intermittently not connecting, though toggling airplane mode on/off can fix it)
- Audio
- Graphics
- Bluetooth
- Wifi Hotspot
- MTP

Does not work:

- Calls (needs testing)
- Camera
- GPS (no fix)
- probably more (need testers)

Download
========

Remember flashing an unofficial ROM on your samsung device will probably void your warranty. Don't expect samsung to support you if you have any issues.

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 for older releases. Or click below for the latest release:

https://forum.xda-developers.com/devdb/project/dl/?id=23245

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-6.0-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 oranother rom make sure you wipe first using TWRP. Coming from a previous version of OMNIRom for SM-T285 may not require a wipe, however please perform a wipe if you encounter problems.

Root and customization
===================

This ROM is a purely based on source and is not rooted out of the box. However you can easily root it by using TWRP to install the latest version of SuperSU.

If you want to customize this ROM and repackage it you may use this guide as a reference.

Possible Hope?

Im Not A Developper But I'm The Closest Thing There Is To It. Il Be Running Some Tests To See If It Might Be Compatable With The Sm-t280 Model. Any Boot.Img I Should Install First?

thanks Jedid-did you have a link here for the ROM as I cannot see it (says status is testing so perhaps a placeholder?) as always great work!

It will be a long shot, there are hardware differences, but nothing stopping you from trying it. Do note that the T280 has a padded boot.img see here, which means you need to get the boot.img from this rom and add an additional header in front of it before you flash it with heimdall or odin.

thanks Jedid

will look in a couple of days when I the Tab back (gave it to a friend)

EDIT

tried the ROM today...calling is a problem (for me) tried multiple times of reboot and allowed rom to settle before making calls (4g and data in out activity was showing-could go to internet)

The call does not connect and sits in dialing mode forever...if you try to hang up it then sits in hanging up mode and will not terminate

(shows a call in progress as if it is still on)...sms works

With all credit to you and all due respect...I stopped there-

think your very FIRST Lineage 14.1 was the best in all the Nougat ROMs

(the next one had issues with the drives seen but not accessible even though the MTP thing was purported to have been solved in that one)-i.e no real files just drives with overall sizes shown and then the lockscreen issue made it unusable (the PIN and notification method was risky as swiping the notification accidentally would lead to an inaccessible phone or maybe demand a reboot)

Works for me

I don't use the Sim functionality at all, so can't comment on that. I had to try a few variations of GApps to get a working Google Play service, and finally managed with the Dynamic GApps 20170215 Minimal build. Once I got that going, everything worked well. I'm using this as my daily ROM on the tablet now, so will report any further issues I have. Just wanted to say a big thank you! This ROM is very fast and smooth.

Original Link worked but the file i got
"omni-6.0-20161209-UNOFFICIAL-SMT285-BETA-3.tar"
did not flash, rejected by Odin.
The new one you have linked works
"omni-7.0-20170219-UNOFFICIAL-SMT285.tar"
Quick scan results:
Mem use 462mb of 1.4gb
Space use 2.71 of 7.28gb
Apps installed 17
Very Similar to Lineage "LINEAGE-OMS-14.1-20171209-UNOFFICIAL-SMT285.tar".
In fact almost exact other than a couple of megabytes and an app.

This is BEFORE SU And APP Remover has gone in to shred some files

Stock rom: Terrible
Mem use 5 TB of 1.4gb
Space use Smoke coming out of 7.28gb
Apps installed Still counting I was sure it would finish last week.

Stock rom: Terrible
Mem use 874mb of 1.4gb
Space use 3.7gb of 7.28gb
Apps installed 64
