Hi everyone one... I am looking forward to making my SM-T280 have a wee better features.

Have modded it with some extra features, but find peeps here are lazy, sor I will be accessing Russian help with a real firmware upgrade for such a great tablet. Will post more info soon.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
Major change up

Seems that while waiting, I came up with a simple system file updates from three devices. Sinice the J1 is more compatible to the Table A 7.0 I spoofed the J1 build.prop settings to make Chrome layout look better, whIle system is forced in landscape mode. I also transfered over some system files, which were univereal that were not included in the basic 7.0 tablet.

So far, I have updated my bluetooth profiles and additional automobile connectivity presets, while updating wifi firmware from latest J3 phone firmware running LP. I also included a few J5 additions as well.

Now my tablet is being long term always on tested for stability.

Here is a list of added or enabled features that is on my Tab A 7.0.

FM Radio with recording

Full featured All share services

Samsung Video player with DNLA and pop out play functions

Screen Cast

Car mode with link functionality

Updated bluetooth profiles

Updated settings and system options... which I now forget what was missing, as I am now use to them.

Added missing frameworks and lib files.

Now working on a few lib files for virtual display and quick connect functionality.

An added note... wifi speeds and connectivity are much better now. Before updates I got 33mbps and delayed connections to my home network, now I get 38mbps and a fast connection when turned on.

keep it up !!!!!
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
Quick update.... disabled chrome spell check and found Samsung keyboard easier to manage on spellchecking... though there is some issues still, so I will dive further.

Removed gesture service, since it requires light sensor, and included spen SDK for SNote to load, and talkback to allow voice interaction in accessibility features. Will try and fit in SNote and Voice Note, as the stock firmware is missing key lib files.

Sticking with A3 / A5 Settings2.apk as it is best all around.

Working on Qconnect, S6 Toolbar, and Personal mode.

Will not fix S6_SVoice.zip for direct useage, as it is only for drive link voice operation only. You can use a S4 SVoice as an option for direct useage. But not installed together. Both SVoice and TTS are huge installs, but a lot less than using all Google. Apps. In fact maps and Google play storeally and services are the only Google Apps I have outside of Chrome.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
Ok, I got some of the keyboard spellchecking issues sorted out. Installed the latest open gapps, just to remove most of the Google updates stored on data/apps. Doing so cleans up space and removes some issues with conflicting .so files and apks. Found Chrome was in need of removal on its updates, and I manually copied it into system app folder for the system to make it into a system load when rebooted. Then Uninstalled the update that was chrome left in data/app folder.

Nown for the additional additions...

NOTE4

SVoice Note with voice to text and 3 recording types.

Face Lock functionality

Talkback

No go apps that will not be added... QuickConnect, S6 Toolbox, Smart Stay, Smart Pause, Smart Scroll, Private Mode, and Air Gesture. I gather framework will need adjusted, and systemui may have QuickConnect and Toolbox presets with disabled pointers to launch them.

I may try a few systemui for other devices, like I have with settings2.

Considering how much of the Samsung features I unlocked and added, the only feature I will miss and is worth the effort to attempt further, is QuickConnect. It is a pretty snazzy tool with some interesting features that make it a go to for sharing and connectivity.

When I create a twrp backup of my competed system, it can be restored over existing installation. A dirty flash if you so call it. Just wipe cache before rebooting. It will take about 10 minutea or more, depending on what has been installed.

You can remove some none stock apps as you see fit, as they are for ease of maintenance when flashing clean.

I added a few things to make the tablet more useful for my own use. One is S5 video player. Mainly because it is full featured, allowing pop out video, and built in DLNA to stream from my router media storage and TV box.

If some videos are not compatible, I use aDLNA to launch MX Player for decode that is not compatible to my hardware.

I kept the stock video player, so the additional S5 video player may be removed if one chooses.

One issue is the buttons in S5 Video are not dpi proper on the layout. So black boxes are shown without any context. You can play around to memorize what black box does what, or I'd you are familiar enough with phone style video player pretty 2016, it should not be so difficult.

I debloated the system as much as I could, though many call removing system files that are not required for operation as debloating. Debloating is removing memory consuming apps, not system needed apps. Most all Google Apps are heavy bloaters, in generating cache and data, let alone are bloated within themselves. I tend to stay away from multi platform apks. Especially when there is no need to have ARM8a compatibility in a ARM7 environment. Either figurethane out that Google or stop with your fake and loosely based facts on your betterment of newer platforms. Geezo, my 4.4.2 tablet uses less storage than 5.1.1. And yet it was stated that newer Android is smaller and more efficient. Right? BS... the true facts are right here in my hands

Enough rants... here are the facts. System partition has about 60MB free. Why leave over 500MB free and unused as empty storage? So now you have a maximized system storage for system apps that normally don't get updated. Leaving the updated or user installed apps to use internal or external storage.

Proof it will not cause issues, some custom ROMs will down size system partitions from 3GB to 1GB depending on how minimal the firmware foot print is. So instead of remapping the system partition, I just moved apps into the system.

I have about 900MB free on internal storage running a bunch of streaming apps and CoPilot. The biggest resource hogsite are Google play services, play store, and Samsung TTS with SVoice. Using Google TTS and Voice would greatly consume more valueable storage space.

The 16GB card is my backups and work space for rom stripping. I use a 64GB card for media and apps. There is a script to make External SD into Internal sdcard, so the storage is like what you would have with newer firmwares. Though it is not encrypted, but can be shared between other devices.

So I placed all the installed apps that are not or will never be updated in the system/app folder. Thus increasing my internal storage space by 60MB and more.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
After a bit of testing, I found that Knox will keep private mode from functioning. So, some how during my tests, I must have finished my transfering system files after a fresh restore of stock firmware recovery. Thus a partially functioning personal mode. To me kids mode works fine, so if i shoud need to share, to someone who i dont trust with private data, i can give them kids mode all setup for them to never ask again. mwhahahaha! On the lighter side, you can just setup the guest profile and lockout photo apps and such.

tested my apps to sd script. all apps now allow moving to sd, as expected. YAY!

I released enough internal (sdcard) for 1.2gb free with curent unmoved apps installed. May balance it out further, if needed. Dont have much room to test with as my 64GB sd card has 54GB of music and another 8GB in other files. Will need to invest in a 128GB sd card for that.

Tweaked the build prop for faster responce... just a few wee edits actually. One is stupid simple, yet never seen anyone do it on small ram devices. will add a final additional set of tweaks for small enahancements.

This tablet is actually faster than the Note 8.0 it is replacing, though it is slower on cpu speed, and is not overclocked with a custom Boefla kernel.

still working on a small set of bugs... probably from my data from installs and configurations. Once I clear the internal data, it may recover properly, but i rather identify the issue, as I expect the restore file to be flashed dirty.

Gave up on testing systemUI swaps. Seems like samsung has made non adjustable ui schema on their platforms. I cant even drop or increase dpi on this tablet without breaking ui.

One thing i did like about A3 ui was its noticable zoom out feature with the lock screen image, and has different background, like the S5 phone.

Outside of that, once unlocked boom! Back to lockscreen with a ui crash.

Found one issue with A3/A5 settings... it has a different mapping for a sub menu item. Closes out, without allowing a setting. Seems like phone and tablets are perposely done so component features cannot be shared beteen them. Signature lock will show as an option but impossible to enable. To use face lock i must use a tab4 settings. It would be nice to combine all the features on the A3 settings ui to the tab4 setting ui, as it would alow so much more versatility. The tab 4 settings has audio pointing to a different audio schema which fc the setting ui once selected, since the devices do not share the same hardware. Also the motion section does it as well.

Most all the features are good between the two on our tablet. Not going back to original settings as it seems so limited.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
Slowly making headway...

Found some nice mic and audio drivers... for the life of me, i thought it was cheap hardware making a bit of digital noise with stock system files and any oem or downloadable audio recorder. I went a head and scoured through build dates on stock driver files to find similarities with tab a stock, and any differences.

Because I only use the tab a to do file and os tests, as its the only thing i have, i cant keep backups or libraries of firmwares to gather what i need. Its mostly download search sort and copy what i need. Then delete and download another rom.

Out side of mystery system files, to patch the latest release for the 7.0 tab a6, i am pain stakingly playing with floating logcat, while launching and running apps.

Decided to remove some apks that i use for tools, and do some cleanup for a clean system build backup. It leaves around 400MB free for what ever you want to add to the system.

Found a nice option to try... once i do a backup, is to run virtual exposed. I dont like the modded xposed for samsung odex. It seems slow and a wee buggy.

I rooted this build with a passive kernel and the latest magisk.

I hope to have virtual xposed operational on this build as there are so many xposed modules available.

I did include the tools i use.. fake gps, os monitor, logcat extreme, termux, and csc features for samsung.

Still trying to sort out sip symbols staying active when more than one is listed, after initial touch on the symbol.

Voice note is also having one issue... will not type out words spoken when doing voice note dictation. I assume i am missing some system files outside of the lib folder location.

Will have to search for the proper firmware and find what differences are in the file structure and in vendor.

Have added smart selfie alarm for camera, and additional stylized images for bonus material.

As another bonus i included control screen, to keep the screen orientation proper on difficult apps. It has an option to stay in the notification pull down panel, and fits nicely. Just turn off samsung auto screen rotation before enabling the app.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
One down two to go!

I found an Svoice that is fully functional on our tab a6 models. So, consider another bonus in the round of fixing wee issues.

This one allows the change of the wakeup command. It seems to work with any command you want to make it. Problem is if you bypass the initial setup, it defaults to Hi Galaxy. I think clearing out all the Svoice apks data and cache will allow changing the command, if you need to.

Still working on Voice Note not typing out text from voice input, and sip symbol key list staying on after initial touch.

It may be from a hidden accesibility function that is available with various setup ui apks.

Like there is another type of unlock scheme on some phones and th J3 version i am using. It very much like pattern unlock but more simpler. Also it can be setup to show direction, or not to show direction, to keep the lock screen blank. Also read out loud to where your direction has been entered.
[Samsung Galaxy Tab A series Guides, News, & Discus] gooberdude:
Down to one last issue to correct

I figured out the main reason why voice note in the voice recorder fails to type out text during voice recording. The tab a6 does not have a proper audio mux and lpcm setup. I tried to configure media by seeing what can be done to add paths. I am not familiar with paths enough to compare and cross reference unknown values to replace from a different schema.

So, until someone who is following can do a proper patch to the media xml files in exec folder, the function will never happen.

I checked with SNote and it does allow all the importing functions, including video from rear camera.

While trying out the patch on my own, I did bump up the recording quality on the video encoding. At least i got something done out of the deal.

I also gave up on virtualxposed. I dont care to run a shell based setup, and most of the xposed modules i use do not play well with the shell.

So, it looks like i will devote my time into isolating the troubles with sip symbol shortcut overlay not clearing from the keyboard after initial symbol touch. It will clear on just a single symbol being shown, or if you touch away from the pop up symbol set.

One thing i did do is clear keyboard data and cache. I may have to reset the csc features xml additions i had set. I have other ideas, but i will tackle the simplest first.

I hope to post my dirty flash mod for peeps with the latest firmware to use on their Tab A6 7.0 tablets.

Since i had very little input on what most want or expect on a modded firmware, i made it for my needs, based on a full Samsung Experience, with minimal google bloat.

I will make a couple of scripts for peeps to run via terminal command or launch from smanager. Since my force installs to external sd card may get in the way of a clean flash with pushing restoration installations.

The scripts will enable or disable force to external sd, and toggle performance mode, and interactive mode (stock default).

All fixed!

Found my symbol key issue was with magnification gestures enabled.

Now that all correctable issues are resolved, I will finalize my small tweak options for user enabled optioms

I will not have busybox installed, just Magisk rooted with passive kernel.

So, speed tweaks are user enabled after boot. Network tweaks are enabled via sysctl.conf within etc folier

Right now I am happy with over-riding system governor to Perfromance and WiFi congestion control to Reno. Both are the only options avaliable from what the kernel was built with.

There is a small battery increase, but mostly noticeable when comparing to low tasks and multi-tasking. Heavy usage and average use, will not show much difference. I have yet to see a reason to revert back.

This is a stock rom with as many features one can have for the hardware and what Samsung made available for cross compatibility. I have included a full featured accessibility package, along with voice and finger generated spen controls. Plus enabled internal editing of videos and photos. Plus I blocked media from scanning system media for images and songs.

There is too much to explain here, but I will try to compile a full list of features that are installed for a Samsung Experience.

Test image

Here is a TWRP backup of my system. It can be flashed dirty, though i recomend doing a backup of your system before flashing to revert back if needed.

Unzip the contents into your existing twrp backup folder. Run twrp to restore the image. Be sure to enable checking to gaurantee proper restore.

This has install to external set, and magisk root with permissive kernel (you may need to enable it with a utility or shell command). Minor tweaks are in build.prop, you can revert to original build.prop by renaming the backup by removal of the bk extension.

This is 98% completed... i have to update a few files and an app, as they were written over, by mistake.

You should have 200mb free in the system partition. Also a small handful of utiltiies that are no more than 25mb total. I removed google bloatware, and a few Samsung apps that are not required, or can be downloaded from Galaxy Apps or Google play.

Many will just say no need to change a thing... but before i post the final image, i will not bother with future maintanence. So, if any one finds something out side of known issues, given in my update history... (please read through carefully) i can attempt to make some additional changes before i finalize. Thank you.

Hi :) the files are zipped TWRP backups.

First, extract the downloaded file with any file manager and copy it to your device.

Then, boot to your TWRP recovery and make a backup of your current installation if you like.

Then, just perform the default wipe (you can also wipe /data if you like), go to "Restore", tick all partitions and restore the backup.

Then, just reboot and enjoy the ROM. I hope I could help you :)
[Samsung Galaxy Tab A series Guides, News, & Discus] danilw:
Thanks for the reply ! But i have some doubts, I never did it before, so i need more details, sorry.

Hi the files are zipped TWRP backups. (ok!)

First, extract the downloaded file with any file manager and copy it to your device.(ok, copy in any place? any folder?)

Then, boot to your TWRP recovery and make a backup of your current installation if you like.(TWRP Recovery?)

Then, just perform the default wipe (you can also wipe /data if you like), go to "Restore", tick all partitions and restore the backup.(defaul wipe?)

One more question : there are few stuff on your mega, including 2 finals , mod, and christmass rom. Which one to use?

Nice mod!

Very impressed with your detailed steps into the T280 upgrade/mod.

I sure like to do this on my tab.

Keep you informed about my progress.

In your region files, i found the Dutch (NL) language is missing.

Any idea where I could find this?

[MENTION=3105344]gooberdude[/MENTION] Thanks for image! Breathed some new life into the tablet. Thanks! I appreciate it!

Question relating to Magisk. I've installed latest, via TWRP, but I have 2 issues;

Busybox is not recognised after reboot, and same with Magisk's Systemless Host, it won't stick after reboot either. Any fixes / ideas?

Thanks again!

Hi [MENTION=10961233]m11e[/MENTION], could you please help me buddy? Appreciate your help !
[Samsung Galaxy Tab A series Guides, News, & Discus] BrikHaus:
First, extract the downloaded file with any file manager and copy it to your device.(ok, copy in any place? any folder?) - Yes, anywhere is fine.

Then, boot to your TWRP recovery and make a backup of your current installation if you like.(TWRP Recovery?) TWRP needs to be installed before you can backup your tablet and then write this image.

TWRP is installed into your recovery partition via ADB Sideload. See here- https://www.xda-developers.com/how-to-install-twrp/

Then, just perform the default wipe (you can also wipe /data if you like), go to "Restore", tick all partitions and restore the backup.(defaul wipe?) Yes

One more question : there are few stuff on your mega, including 2 finals , mod, and christmass rom. Which one to use? Just use the one OP has linked to.
