[MENTION=4899305]ashyx[/MENTION], does the boot image change during an OTA release? I am waiting and crossing my fingers that the T280 gets marshmallow soon. Just wondering what affect it will have on the existing boot image.

Thanks

What is the steps of rooting T280?

Just copy SuperSU to memory card

Flash TWRP with Odin

Uncheck reboot and power it off after flashing

Turn it on in recovery mode (I forgot the key combo)

Flash SuperSU in TWRP

Format cache and Dalvik cache

Reboot?
[Samsung Galaxy Tab A series Questions & Answers] ashyx:
You also need to flash the padded boot image afterwards or the Magisk boot image.

No need to wipe cache or dalvik.
[Samsung Galaxy Tab A series Questions & Answers] sssscary:
Hi, I was wondering if someone please could give me some advice on what to try next on my T280. I installed the TWRP_3.0.2-1_SM-T280_25916 recovery and can boot into that. I then installed SuperSU, I tried to install the

File Type: gz	boot_sepolicy_patched_280.img.gz but then I was stuck in a bootloop after restarting. Goes through samsung logo and restarts.. I then tried the boot_magisk_v6_sm-t280 with the same results. I tried clearing the caches with TWRP.

If anyone has the original boot image, maybe I should go back to that?

Thanks for any assistance!

Update: i used the wrong version of SuperSU.... i just tried SuperSU-v2.78-SYSTEMMODE.zip - and it is now booting with root. thanks!
[Samsung Galaxy Tab A series Questions & Answers] jedld:
I don't think you need to install boot_sepolicy_patched_280.img.gz. running chainfire's supersu installer using twrp should already patch the sepolicy for you and install root. In my case I also didn't need to flash a new boot image, note that magisk and chainfire's supersu don't play nice together, I suggest to use phh superuser instead. Here are the steps I took for a clean magisk install:

1. flash stock boot, system images.

2. flash appropriate TWRP recovery for your device

3. install magisk using TWRP

4. install phh supersu using TWRP

5. install systemless xposed using TWRP

reboot into samsungs bloated stock firmware.
[Samsung Galaxy Tab A series Questions & Answers] ashyx:
Will still need the patched Magisk boot image or the padded one you posted or it wont boot.
[Samsung Galaxy Tab A series Questions & Answers] jedld:
oh yeah, the SM-T280 has a different boot image format that is different from what magisk generates so I guess that is needed.

T280 should be here Monday.

Stay tuned and I will make a guide how to root it.

BTW, we discovered an ultimate way to root Android.

Adding security keys on custom kernel and recovery will be a reality. It can bypass locked bootloader which makes rooting totally possible.

---- update ----

I received the unit.

It asked me to update to PH3

Should I do it?

---- update 2 ----

Updated to PH3 and TWRP flashing didn't work

Secure Check Fail: (recovery)
[Samsung Galaxy Tab A series Questions & Answers] mingkee:
Successfully rooted T280.

Guide:

Prerequisite:

Padded kernel for T280

http://xdaforums.com/attachment.php?attachmentid=3881481&d=1474417563 (unpack with 7zip and put it to memory card)

SYSTEMMODE SuperSU (REQUIRED)

http://xdaforums.com/attachment.php?attachmentid=3861602&d=1472738213 (put it to memory card)

All required drivers from Samsung Smart Switch

Odin 3.10

TWRP

https://www.androidfilehost.com/?fid=312968872162492913

Your unit should be fully charged

OEM unlock and USB Debugging enabled and allow your host computer

Steps:

1. Connect your tablet with your host computer

2. Open prompt and locate to your adb folder (platform-tools) and enter

adb reboot download

If it doesn't work, look at your tablet to see any prompt to allow your host computer

3. Open your Odin. Make sure auto reboot is not checked (but TWRP isn't overridden). Choose AP and locate your TWRP file. You may see secure check failed. Don't worry. Just press and hold power+volume down+home key together and wait for few seconds.

4. Enter TWRP by pressing power+volume up+home key together. You should see the boot screen. Keep pressing these buttons until the boot screen disappears. You should enter TWRP.

5. Locate your memory card. Flash systemmode SuperSU first, go back, and flash padded image as "boot".

6. (Optional) wipe cache and dalvik cache.

7. Reboot

8. It may take a while to boot up

9. You tablet rooted.

Will this allow me to flash custom ROMs?

Also I just wanted to thank everyone on this thread for their hard work, the Rooting process proved to be fairly straightforward once I knew what I was doing, this is my first android device, and I look forward to learning the ins and outs of it. I am an iOS jailbreaker and have been doing it for years. I always was aware of the idea of rooting an android device, but this is the first device I got that actually had android on it.

[Samsung Galaxy Tab A series Questions & Answers] HankeyP:
[MENTION=649003]jedld[/MENTION] Thanks for the work you've done so far on this! I just got a T285 and flashed your TWRP, which works good enough (it has the lag you mentioned earlier, but I can live with that). But after applying SuperSU, I get stuck in a bootloop :( (it shows the Samsung logo for a while and then reboots). I used SuperSU-v2.78-SYSTEMMODE.zip found on http://xdaforums.com/apps/supersu/v2-64-2-66-supersu-mode-t3286120 and tried it with both the Install option in TWRP, and the ADB Sideload option in TWRP.

Did I confuse it with steps needed for the T280, should I have used the SR1-SuperSU-v2.78-SYSTEMMODE.zip, or should it have worked and is something else messed up? Booting with just TWRP flashed, without SuperSU, works fine btw.
[Samsung Galaxy Tab A series Questions & Answers] jedld:
Haven't tried with that version of SuperSU unfortunately, have you tried with the standard SuperSU install?
[Samsung Galaxy Tab A series Questions & Answers] HankeyP:
So I did mix instructions for the T280.. :P No I didn't try it with the 'normal' one yet, since I would rather have 'systemfull' root than systemless, but I will give it a shot right now!

---------- Post added at 11:07 AM ---------- Previous post was at 10:59 AM ----------

Using Install in TWRP with the zip file downloaded from the url provided in http://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133 results in a successfully rooted tablet. Thanks :)

Do you think there's any chance we can get 'systemfull' root somewhere in the (near) future?
[Samsung Galaxy Tab A series Questions & Answers] ashyx:
I think you're getting confused as to what systemless root is.

Systemless root is still full root. It just doesn't alter the system partition.

You can get system root anytime you want.

Uninstall supersu.

Type the following in a terminal then reinstall supersu.

echo SYSTEMLESS=false>>/data/.supersu
[Samsung Galaxy Tab A series Questions & Answers] HankeyP:
I'm well aware of the difference between systemless and 'systemfull', I just like systemfull better than systemless. It's just a matter of personal preference really. As for the echo part, I tried that once on a phone which made the phone bootloop as well, so I kind of considered that method to be bugged. I will give it a try nonetheless :)

---------- Post added at 12:04 PM ---------- Previous post was at 11:50 AM ----------

And as I feared, and expected, the tablet is now in a bootloop after reinstalling with the SYSTEMLESS=false method applied.

---------- Post added at 12:44 PM ---------- Previous post was at 12:04 PM ----------

I figured if SYSTEMLESS=false really was bugged, there would be more people asking for it. So I decided to dig (Google) a little deeper into this. When completely uninstalling SuperSU, it asks if you want to restore the original boot image. The first time I tapped Yes, because I wanted to uninstall SuperSU, right? Turns out you need to tap No, so that the boot image is still selinux-patched which is needed for it to work. So, to sum it up:

- Install systemless SuperSU

- Uninstall SuperSU (complete unroot) but do not let it revert back to stock boot

- Do the

echo SYSTEMLESS=false>>/data/.supersu

thing from recovery

- Install SuperSU

- Win.

I'm sure a lot of you already know this and consider this a useless n00b post, but who knows.. maybe there's 1 or 2 left who still don't and can benefit from it.

Either way, thanks [MENTION=649003]jedld[/MENTION] and [MENTION=4899305]ashyx[/MENTION] !

[Samsung Galaxy Tab A series Questions & Answers] jedld:
To return to stock you need to download the stock firmware package for your device. There are various sites that provide this, go look for "SM-T285 firmware". After you revert back to stock using Odin or Heimdall you should flash the TWRP package for the SM-T285. After flashing TWRP, you can now flash SuperSU using TWRP after that. Note that steps are a little different for SM-T280 users.

You can flash SuperSU 2.78 System or Systemless. Both works fine, it is up to you, I've tried both. Installation instructions are standard like any other rootable android device. No special steps need to be taken for the SM-T285 unlike the SM-T280.
[Samsung Galaxy Tab A series Questions & Answers] jedld:
Hi please provide detail on what you attempted to do. You can generally fix MDM mode errors by flashing back to stock using Odin.

it is also very difficult to download from mega.co.nz since it does not support downloading from a download manager like wget, or aria2. (linux)

Does this tablet feature the knox? I am new at samsung tablets/phones since the 2.3.6 android does not appear to have knox?

[MENTION=649003]jedld[/MENTION] does your ROMs feature the "Encrypt Device" function? and is there really a TWRP or CWM recovery for the tablet without triggering the know if there is? about the rooting I am very confused since there are a lot of info on rooting but they seem to be outdated?
[Samsung Galaxy Tab A series Questions & Answers] jedld:
I'll see what I can do, XDA has increased its download limit to 2GB.

I don't think this tablet ships with knox enabled, looking at the binaries I don't think it even supports it. The flagship devices do support them and some phones do.

I don't think so.
[Samsung Galaxy Tab A series Questions & Answers] gian20:
I don't think so.[/QUOTE]

Im sorry about the post above I have made mistakes. The stock firmware 'official' when I bought the tablet has the 'Encrypt Device' functionality which can be found o 'Settings > Lock Screen and Security > other security settings > Encryption', since you have 3 firmware? projects the andr 5.1, tinkerer, tinkerer (root). andr 6 CM13, Omni, Andr 7 (experimental) which of them has the encrypt device capability?

Mega.co.nz does not support direct linking, and the 2gb limit of XDA which means the ROMS are 2GB+? Can it be highly compressed by 7zip / rar? (bandwidth limitiation + slow internet in PH)

How do I manually root the device, i don't have the stock firmware from sammobile since it is 1GB and a non resumable download and very slow internet speed. (I have attempted download until 843Mb then the internet is gone, bandwidth limit maybe), cannot find a direct link download nor torrent download link option.

Is there CWM or only TWRP available for the device and how to install it, can I flash via Linux PC or should I use *cough*Windows?

Currently the device is encrypted will it be a problem if I root it and install a custom recovery.? I just want to install a AFWall to control the apps which has internet access, to force block their internet access since there are 3rd party and bloatware still installed.... Thanks

see post below
[Samsung Galaxy Tab A series Questions & Answers] jedld:
I believe CM has encrypt device under Settings->Security. I seriously haven't tried that yet so I have no idea if it works or not. For OMNI, I need to go back and take a look, I'm on CM right now and would need time to try it out.

I think the stock ROM is below 2GB, I'll try to upload it later under the Tinker V5 thread.

I also have a hard time downloading the stock firmware here in the philippines using https://samsung-firmware.org/. I had to cough up a subscription just to get a couple of firmwares downloaded properly

TWRP is available for this device here. In theory I can build CWM, though is not as good as TWRP and it doesn't support flipped framebuffers properly so I wouldn't waste my time with it. If you don't want to use windows you can use Heimdall for Linux which is also what I am using right now, you just need to spend some time to set it up. Once you install TWRP you can easily install SuperSU with it.
[Samsung Galaxy Tab A series Questions & Answers] gian20:
[MENTION=649003]jedld[/MENTION] ok thanks, I don't actually use CWM, since I used TWRP on my Xperia device.

Okay the steps are: 1. Odin/heimdall flash TWRP from your thread,( i might not install it now because I don't have a odin flashable recovery stock firmware in case of emergency)

2. download the supersu from the t280 thread, (http://xdaforums.com/galaxy-tab-a/development/recovery-samsung-galaxy-tab-a6-sm-t280-t3475381)

3. flash it using TWRP

I have a problem in my SM-T285 the Device is encry pted with a password. After the device locks, the keyboard is gone from the lock screen so you can't type the password. I don't know if this is a bug but I am using the default samsung keyboard and hacker's keyboard (fdroid). Anyone encountered this issue? I don't know if this persist only in encrypted devices... I've tried resetting the device to factory defaults and encrypting again so it maybe a bug? I am using the stock firmware that was released on Mar 2016. (initial firmware)

I have rooted and installed TWRP. and changed the boot password from the screenlock password.

Upon entering the boot password the android boots and displays the lock screen. the keyboard popups for about 30 seconds and disappears forever* since you cannot unlock the tablet because there is no keyboard popping up. (might be a BUg in android?)

Is there a way to force change the screenlock password to a pattern lock? It is greyed out because I have used the device encryption...

Not entirely true, SuperSU makes permanent changes to the boot and system partition that survives a factory reset. The only way to remove SuperSU/root is to flash stock boot and system images.

FRP lock after missing OEM unlock

Hi all,

after installing a custom ROM with root (thanks, ashyx and jedld), the device worked fine - until the reboot. I had missed the "OEM unlock" part. The device is a 280 Now the only modes that work are Download and Recovery (the latter after Samsung returned the device). All other modes show the Custom binary blocked by FRP lock-message. I tried downloading a stock rom from sammobile, but flashing it did not fix the problem (maybe I chose the wrong ROM, there are quite a few to choose from).

Any help? Thanks in advance

Installing the correct firmware for your device region will remove the frp lock.

Do NOT factory reset your device while the lock is in effect.
[Samsung Galaxy Tab A series Questions & Answers] serv-inc:
Thanks. So how to determine the correct firmware? Should I just try all 4 that exist for my country? And should I flash all images (including sp2.img etc)?
[Samsung Galaxy Tab A series Questions & Answers] ashyx:
Not sure you're flashing the right thing there.

The firmware package will be in md5 format and will be flashed as a complete package with odin.

[Samsung Galaxy Tab A series Questions & Answers] random4t4x14:
Maybe, one day?

The problem with the SM-T280 is that we don't yet have a working selinux permissive kernel. I imagine once that happens (if ever), we'll see other ROMs. For now, I'm more than happy to run jedld's custom Tinker Edition on my SM-T280.

If anyone is willing to part with their T280 or donate one to me, I'll be willing to work on it. It is quite unfortunate that the T280 isn't offered in my country otherwise I would have taken care of this device by now.
[Samsung Galaxy Tab A series Questions & Answers] One.Hit.Kill:
If anyone starts a donation page to get jedld to get an SM-T280 let us know. I'll definitely donate at very least $50. The SM-T280 is around $130 in the USA at most retailers. I can't imagine shipping being more then $50 reguardless which country it is going to. So this should be somewhat easy to achieve.
