I'm guessing none of this is working for the T280 with firmware T280XXU0AQL4?
fastboot is not even possible.

I've been screening the forum for the past 3 days. It would be great if someone was able to tell me i completely missed something for the T280 with that firmware ... :)

Fastboot is not possible on any Samsung device.
Also no reason why the T280 rom still won't work.
Samsung have hardly updated this device since it was released.

does that mean that i can flash the Tinker rom for example through the samsung recovery? I'm a bit lost it seems.
I thought i needed twrp (or another custom recovery) to flash a new rom and to flash a custom recovery i needed a rooted device for which i need fastboot...

If i remember correctly my S7 edge had fastboot. tripped Knox however ...

I highly doubt the S7 had fastboot.

Samsung devices use ODIN as instructed in the OP.
And no you don't need a rooted device to flash twrp.

Quick question..is it possible to remove SU and flash Magisk instead? I read a comment here I believe saying Magisk causes bootloops..?

I flashed it after noticing that Lineage OS for this device has no working GPS. Is bootloop a normal behavior for deodexed ROMs? Looks like it doesn't work for me... BTW, I've got the 285 version

CIFS

Thank you for your work so far. I was able to get my tablet to boot with version 5. I have been trying to figure this out for myself, but it has proven very difficult. Are you able to add support for CIFS? It seems like mounting an network share would be trivial, but it is apparently very difficult with Android.

Hi, this rom is great, i've been using it for 2 years. But recently i have an issue with bluetooth. The bluetooth is connected with my speaker well, but the sound is playing only on my tab, not on my bluetooth speaker. Any workaround on this?

Thanks

I know this is an old post, but is there any chance of V5.1 being released for the SM-T280? I'd like to use this ROM, but I really need a working SD card.

Maybe new firmware???

I have found out a place that says that there is an Android 6 firmware (Pakistan) for this device, but I coudn't confirm anywhere else.
This does not seem correct, so I don't recommend trying it. But if it is, maybe good news for the devs and for us?

PS: This firmware is available on updato.com.
Country / Region: Pakistan
PDA: T280XXU0APK1
Product Code: PAK
CSC: T280OJV0APK2
Phone: T280XXU0APK1

It's android 5.1, there is no MM for this device.

Hi all,
This may be a silly question but is this ROM lighter on power use? The reason I ask is I use my device for a GPS in the van. Currently, under stock ROM it is using power faster than it can charge! Yes, I have checked the rate of the charger it's a dual port QC3.0 charger, currently using the original cable. Let's just say the charger handles my S9+ beautifully! & used to also power a Lenovo TAB 8 (ditched that as it couldn't take a sim!) I would try the 7.11 ROM by jedid but don't think the GPS works in that? I stand to be corrected. Thanks

I just flashed this rom on my smt280. everything works fine for me. my problem is xposed. the only reason i use the smt280 is for the game "summoner wars". the game recognizes xposed and killed the game for "hacking" warning.

i dont really use xposed so i tryed to deinstall the app which doesnt seems to work. the button in the app is grey and cant be clicked. deactivate the app trough the system doesnt work either (the game detected xposed aswell)...

is there a way to deinstall/deactivate xposed?

Reflash the rom.

    Samsung Galaxy Tab A 7.0 LTE/WIFI 2016 TINKER EDITION ROM (DEOXED/ROOT/XPOSED)
    ============================================

    Update 01/04/2017
    -----------------------

    Tinker Edition V5.1 is now out.

    * Re-added Samsung stock camera and gallery
    * revert back to stock vold to fix issues people are having with micro sdcards

    Now available for the SM-T285, SM-T280 to follow

    Update 10/29/2016
    ------------------------
    TWRP for the SM-T285 here

    Early Build of TWRP for the T285 (see post by @ashyx will update this if an official version is released. The T280 version should be available not far behind I believe :)

    Update 09/21/2016
    -----------------------
    V5 now out (root, deodexed, xposed) for the SM-T280/T285, still working on the SM-T280

    Update 09/20/2016
    ------------------------

    Turns out this device is not as locked as we all thought it too be. See thread below for my ordeal and more details:

    http://forum.xda-developers.com/galaxy-tab-a/help/resources-samsung-galaxy-tab-7-0-2016-t3431022

    Modifications:
    ===========

    * Based on LMY47V.T285XXU0APCN
    * Stock Boot and Recovery (Not much choice since the bootloader is locked)
    * Busybox
    * Hijacked Vold (using CM 12.1 sources) to run shell scripts stored in /data/scripts/vold.init
    * Removed Touchwiz launcher and redundant samsung apps (Hancom office, Kidzone), replaced with Trebuchet
    * Enabled r/w to the external SD Card
    * Dolby Atmos mod (09/11/2016) (thanks to @Nando14sunny)
    * Deodexed/Xposed (09/13/2016) (thanks to @wanam and @rovo89)
    * soft linked /etc/hosts to /data/scripts/hosts and can be edited using adb shell (09/13/2016) (thanks to @venomrat)
    * V5: root chainfire's SuperSu 2.78 (09/21/2016) (thanks to @Chainfire)
    * stock boot animation

    Special thanks also to @ashyx for initially taking a look at this device , I haven't given up on rooting this device yet.
    Special thanks to @klemen241 for helping me try out the SM-T280 build

    Haven't done extensive testing on Xposed modules, but the pokemon go iv mod/hacked worked and that was good enough for me :) (Before pokemon Go was patched). If you use this ROM feedback is highly appreciated

    NOTES: To be safe, perform a cache wipe using recovery. I didn't need to do this personally but I haven't tested all use cases
    NOTES: Since this rom is deodexed, the first boot will take quite a while, so please be patient :).
    NOTES: if you are coming from V2 and are using the mount_ext4 apps2sd scripts please update it for additional support for the V3 ROM HERE:
    https://github.com/jedld/smt285_data_scripts

    NOTES: (09/13/2016) Unfortunately, the V3 build fails the Google SafetyNet check, will be a problem if you play Pokemon Go

    Other Notes: Removed support for zygote.init scripts in V3 as I am now using the app_process32_xposed binary, will work to get this back soon. I haven't had a need for zygote scripts though. The vold.init scripts shoud still work as before if you are using the apps2sd script

    Installation Instructions:

    Odin or Heimdall Required. I you are coming from the Stock Rom please wipe/factory reset to be sure. If you are upgrading from V1 or V2 you are not required to wipe unless there are problems. If you are upgrading to V3 cache wipe is recommended using recovery.

    --FLASH AT YOUR OWN RISK--

    1. Make sure to backup of your data and have a copy of your stock Rom in case something goes wrong.
    2. Make sure your device is OEM unlocked. (Enable Developer settings and Enable the OEM unlock settings)
    3. Extract ZIP file below and flash the tar.md5 file using ODIN, for details on this kindly look for instructions in the xda site.
    4. For Heimdall you can use 7zip to extract the system.img from the tar.md5 and just flash the system.img itself.

    Choose the appropriate download for the model (wifi only T280/ lte T285) that you have:

    If you have suggestions, send me a PM.

    Other Notes (So people don't have to ask):

    * I've tried to run superuser daemonsu, but unfortunately the sepolicy scopes for vold and zygote are too narrow in this device for supersu to use despite being root. In theory a version of daemonsu can be made specifically to run on this device with a somewhat castrated functionality though I don't have access to the source code to figure it out. Navigating the sepolicy landmine is hard.


    WIFI ISSUES
    =========

    There are reports of wifi problems with the latest build due to wrong permissions with dhcp hooks, if so you can do the following (big thanks to @_mone):

    Using adb shell:

    Code:
    su
    mount -o rw,remount,rw /system
    chmod 755 /system/etc/dhcpcd/dhcpcd-run-hooks
    mount -o ro,remount,ro /system

    /system is readonly by default, which is why you need the remount commands. Reboot your device after just to make sure.

    We don't have a custom kernel for the SM-T280 yet

    Hi, does this rom have selinux set to permissive? I really need it for my t280!

    The T280 uses the stock kernel, so no. However there might be some devs willing to build a permissive kernel for the T280.

    Coming soon.
    5

    Hi there!

    I'm still working on a proper custom kernel for the T280.. Samsung made this device extremely difficult to work with.. Depends on what I add to the kernel the device won't boot, even if it's just a governor or some minor modifications that I'm used to include in the kernel of my other samsung's devices.
    Today I saw your post and I've decided to share at least what I'm able to as of now, and that is a kernel that is able to set selinux to permissive (still trying to find out wtf is the trigger for the no boot).. so I've flashed this tinker edtion ROM (first time for me), made a quick set up (everything worked fine), then I've compiled a kernel (AQA4 sources) with my usual selinux patches, decompiled the included boot.img with the tinker edition ROM and replaced the kernel with my newly compiled kernel, repacked everything, applied the usual patches to the header, flashed the new boot.img and the device was in a boot loop.. So I tought was a kernel source problem, and I've used and older one (T280XXU0APL7) to compile the modified kernel and done again all the steps... again boot loop!
    Then I've remembered.. when I bought this device there was no AQA4 sources (kindly provided by samsung's OSRC when I asked for it), and I've started to work with APB6 and APL7 sources.. with those sources I was able to compile a kernel that I could use for a custom recovery but not on a samsung's firmware. Only recently I've started to work on samsung firmware because my LineageOS port was going nowhere so I've decided to try to understard how the samsung mess works like that I may be able to learn something that can help me to finally get rid of samsung's software.
    As for now I'm working on T280XXU0AQA4 and T280XXU0AQF1 firmwares and I'm able to modify how I like the system in my device but not able to create a proper system.img to share with the community (I'm having some issues with google play store), and I'm able to use a "limited" custom kernel (based on AQA4 source as AQF1 has not been released yet "already asked for it") with both firmwares..

    In conclusion: If you want a permissive kernel, with patches for your favourite root method, for samsung's official firmware AQA4 or AQF1 I can provide it with no issue, but I can't provide a custom kernel for this ROM in its current status, if @jedld updates it with a recent samsung's firmware there will be no problems in running a permissive kernel on this ROM.

    E.T.A. of SM-T280 ??

    Is it possible to run V4A on this rom?

    ---------- Post added at 03:37 PM ---------- Previous post was at 02:50 PM ----------

    Also I do not see BusyBox.

    hay.

    when v6?
    thx and respect from italy

    Soon, I just got caught up porting OmniROM 6.0 to this device. I'll start working on it immediately once I give up and conclude that 5.1.1 is the best it could get.
