[Galaxy Tab S2 Android Development] Dead Cell:
Bricked?

Guys, I followed the steps to install Lineage without an SD Card or a computer on my Tab S2 , and copied the ROM to the internal memory of the phone, but one of the steps in the instructions is to wipe the DATA, which means that the ROM is deleted LOL.

Anyway so I am now in a situation where the TAB S2 is stuck on the Samsung logo. I can get into Recovery and wipe data etc, but nothing seems to work.

I don't have an SD card to hand so I'm unable to load the Lineage ROM and install.

Just to add I'm new to all this. Only today I downloaded ODIN and installed TWRP recovery, although during the flashing progress ODIN reported successful, however on the device itself, it was stuck at the very last bit of the progress bar with a message that it's still in progress.

In the end I had force reboot the device and I can now see it shows 'Custom' for Current Binary and System Status, and the fact that I can get into TWRP recovery tells me that it worked fine.

I tried to sideload the Lineage ROM using ADB however it does not detect the device and TWRP just says 'Starting ADB sideload feature', and in the command window on my laptop, it says no device detected.

I can't even find the stock ROM and even if I did, how could I flash it? Does ODIN allow the flashing of a ROM? I tried to flash the Lineage ROM using ODIN, but the file format is not supported.

Please can someone help?

Thank you kindly.

If you have a computer, put all the files you need in a folder. Then if you can access twrp in your tablet wipe system, cache,dalvik cache, internal memory and format data(do what is said in op) Then plug your tablet to your computer and in twrp setting there is an option to mount storage. Your tablet should be recognize by computer. Move the folder from your computer to tablet and flash according to op

Sorry, it's me again. ;) I haven't given up on the tablet yet. Some of my attempts involved blanking the system and data partitions. Unfortunately, I forgot to note the file system used for these two partitions before. Can anybody help out? [MENTION=6005084]ripee[/MENTION] - is there more than one option and within that maybe a preference? I used right now ext4 for both (as mentioned for system in some post from December) and feeling is it got even worth while ef2s does not show any errors. TWRP itself runs stable but any attempt to run LineageOS ends quickly in severe hickups.

What is the preferred/required file system for system and data partition for your build on a T710?

On top: Would anyone know an option to test the RAM on an Android device similar to Memtest86+ on x86 systems? And yes, I did search on the standard search engines but nothing useful (besides others asking similar questions) popped up. So, my hopes are not too high.

Re Gmail Dark mode: Nah, tried many things but don't want to hack too much for something as basic. Just harass the Google clowns. All it takes for them is flip a switch. I can't wait to switch to ripee's Lineage 17 build just for this reason but can't afford instability atm and will let it mature a little longer...
[Galaxy Tab S2 Android Development] js-xda:
Could someone please check what is the "normal" / "default" file system for system and data partition? As I am suspecting hardware issues (first guess storage but maybe something else), I wiped both partitions completely using dd and need to create a new file system afterwards. I forgot to note down the file system used for them. And I know from other custom ROMs (e. g. I9100) that there are sometimes preferences by design.

For checking using TWRP:

boot to recovery (Power+Volume up+Home)

go to menu "Wipe"

DO NOT "Swipe to Factory Reset" OR "Format Data"

go to sub-menu "Advanced Wipe"

select one by one System or Data

DO NOT "Swipe to Wipe"

go to sub-menu "Repair or Change File System"

check on the line below "Mount Point: /system" or "... /data" the indicated file system

DO NOT "Change File System"!

Thank you!

Changelog

Build 0331 for all variants

* Nothing major, just a few minor changes from Lineage since the last build.

* Synced with LineageOS sources.

The builds are running and all four should be up within 2-3 hours at the latest.

Naturally, Lineage's focus has shifted to Q, but I won't be working on 5433 until I fix up msm8976 (2016 Tab S2). Also, ananjaser1211 will hopefully be getting his replacement screen for the Exynos Note 4 soon enough so that he can help out. This is all I can say about Q right now, I will not reply to any posts asking about it because I cannot promise anything right now.

Guys, bit of advice please. I've read every post on this thread but must have missed something.

I've aT810 running stock. I rooted it and installed TWRP. Flashed the 311 build and everything looked good. Made the mistake of flashing the latest android 9 GApps and the tablet hung on the screen shown. After several minutes it booted into TWRP. I remembered there was a post about going back to the pico 117 build. Returned to stock, rooted again, TWRP again and reflashed 311 and 117 pico. Same darned thing. Same screen then into TWRP. Tried the download screen and cancel trick but no joy.

Any advice and guidance gratefully accepted.

Thanks

I have the WiFi dropouts also. The problem existed with the last official build - 7.1 for my T810 and was the reason I changed to this build. It is great, thanks to ripee for the good work.

My WiFi dropping is worse since I installed a mesh router and it made the tablet unusable. I have made a workaround with llama labs Automate which detects the dropped WiFi and re-enables it. If you want to give it a try it's called "Samsung Tab S2 Wi-Fi fix".

Problems on t710

Hi,

Thanks for keeping our tab s2's alive! Need some help...

I have several serious issues on the rom version 20200311. The previous 20200225?? had the same problems.

Many apps hanging and stopping; x-plore, pixel launcher, nova launcher, others. This also freezes the tablet

Ghost apps on home screen; several apps although still installed, become greyed out on home screen - intermittent

Tablet freezing and black screen: this usually resolves after a minute, could be related to the launchers crashing

Fingerprint scanner not working, setup worked fine, but can never logon with a fingerprint - either ignored or 'not recognized'

BT dropping every few seconds: just on one device a, jabra move. No firmware update available for it - intermittent

button backlighting - intermittent

battery life is poor, have to charge 2-3x/day with normal activity. It's an old battery, though.

Tablet seems laggy and slow

I can't guarantee a recent full wipe install has been done. I will do that if you think there is a chance of resolving most of these issues. Having to re-install and login to apps, plus lose all the LOS settings is a drawback, unless there is a way to save and restore the LOS settings?

Thanks for any help!

Two options:

download whole folder as ZIP (no clue why this overrides the limit but it worked for me in the past)

Also, ripee mentioned as another option a short while ago to link the share to your Google Drive. No clue how that functions as I don't use it.
[Galaxy Tab S2 Android Development] dombo1970:
You should be logged in in Google Drive.
[Galaxy Tab S2 Android Development] bbortnick:
Did a full wipe and reinstall; the following problems remaining are:

1.	Ambient does nothing

2.	Capacitive buttons have no back lighting/randomly work after boot

3.	Google device backup needs device unlocked, counter to gapps requirement, a catch22.

4.	Battery life is poor (probably old battery?), and a full charge takes four hours (not sure what it should be.)

5.	Fingerprint security scanner does not work, setup is ok, unlock not.

recents cards

Weird. I restarted with no changes and the recents cards are now vertical. They no longer have the app icon on top for split screen access.

Button backlight works about 1 in 3 restarts.

Using a high power charger (not factory) charging is about 2.5-3 hours with tablet active.

Btw I am on 20200311 t710.

Update: long press on a vertical recents card brings up a text option, drag here for split screen.

Search the thread for "gapps". I recall there was an issue using versions after 17th January, iirc.

Also use the arm version. I always use Pico/Nano - the less the better :)
[Galaxy Tab S2 Android Development] bmwboyee:
Yeah, sorry about that. I got to the set up on boot and would then go to a black screen. Only way to get out of it was to reset the device.

I ended up flashing the gaps you are referring to and it fixed my problem.

I did flash Magisk and trying to get Netflix to work. Do I have to side load the apk?

I tried that automate-script, but unfortunately it does not seem to detect lost wifi every time. Does it really work reliable on your device?
[Galaxy Tab S2 Android Development] pengarven:
Wifi

It fails maybe once in 30 tries with me, so fairly reliable on my device. I only need to manually enable the WiFi every 3 days or so. A search on Automate using 'Samsung' throws up another WiFi flow which may be better, not tried it, but it does seem to indicate a Samsung issue. Try changing the flow perhaps you can 'tune' it to your device.

[Galaxy Tab S2 Android Development] shutdown-h_now:
[MENTION=2694248]cristilamba[/MENTION]: Yes it is.

Edit: I was wrong: No, it isn't! The platform is ARM not ARM64

You're absolutely right, [MENTION=752465]kabelgleichung[/MENTION] and [MENTION=5686504]tzutolin[/MENTION]!

I don't use Open GApps ... therefore my writing was faster than my thinking ;)

Thanks for your answers, but for my t715 with Exynos processor it is another ROM which has 64 bit build? I searched in forums but nothing concrete...
[Galaxy Tab S2 Android Development] shutdown-h_now:
Now I' m hopefully not to fast at writing ...

The Exynos CPU is 64 bit capable, look at https://en.wikipedia.org/wiki/Exynos, this was my error in reasoning in post #1065.

But

- LineageOS 14.1 (Nougat) is an ARM (32 bit) platform and

- LineageOS 15.1 (Oreo) and above is an ARM64 platform.

If you're on LOS 14.1, you're on 32 bit.

Look for a LOS 15.1 build or above to use ARM64.
[Galaxy Tab S2 Android Development] cristilamba:
Thanks!

I don't find LineageOS 15.1 and 16.0 is 32 bit OS.

I guess I must buy a tablet with native 64 bit OS...damn!?

Magisk- Malware

So, like the title says.

Am i the only one?

I ran Clamscan on my stuff, and Magisk came up as Adware/malware-PUA Scan.

i couldnt save the read out, and i dont have a Win computer setup with scanners yet. So, if anyone can corroborate for me. I'd appreciate it.

Thanks

PS. Also- is there a checksum for addonsu? I have the one for arm64, but not arm.
[Galaxy Tab S2 Android Development] ripee:
This is completely FALSE! Chipset architecture has nothing to do with the Android version. If you wish to write 64-bit drivers for 5433, go ahead, but Samsung never released them because all 5433 devices have no more than 3GB of RAM, thus no need for arm64.
[Galaxy Tab S2 Android Development] shutdown-h_now:
Thanks for your clarification!

I didn't know that, but now I understand it's like with Windows 32 and 64 bit, also only support for 3 GB of RAM with 32 bit version.
[Galaxy Tab S2 Android Development] SubCool:
At what point do you as the addsu?

I use to have it working.

I just reformatted my tablet and can't get it on.

And maybe I'm missing a section to format?

My background is the same, but... I followed the instructions.
[Galaxy Tab S2 Android Development] SubCool:
Ok seriously. I feel like an idiot.

Lineage 16.0 - 20200331 gts210wifi

I've added addsu:

after Lineage install,

before gapps.

After gapps

Every time su checker says failed.

I don't install magisk because of the supposed malware.

At this point I'm adding it after everything I do.

Edit: further reading. I was to unstand that magisk was just an api safety thing so you can use Netflix and such.

I didn't know it was its own su kit.

So it and addsu are needed I assume.

ANY CLARIFICATION would be helpful.
[Galaxy Tab S2 Android Development] sal82:
Use magisk, dude. Some custom stuff will always be flagged, even though there's nothing wrong with them. Furthermore, I don't think the makers of magisk would risk their popularity by infecting the files.

The only thing you should be worried about is where you download it from.

Problems installing on T710

I am trying to install on a T710 and it boots to the LineageOS logo which keeps animating but never gets any further after 20+ mins. I followed the instructions to the letter. When I started I had Stock firmware build number NRD90M.T710XXU2DRG2 and ran into this problem (and also tried and AOSP rom which also had the same symptom). So then I reverted to Stock version T710XXU2DRH1, which booted fine and then tried again, same result.

Do I need to specifically update the kernel or bootloader to something special before installing?

[Galaxy Tab S2 Android Development] reinhaezer:

[Galaxy Tab S2 Android Development] PsymonDK:
I've had an issue on the previous release with the tablet suddenly dying, so updated to the current release with a full wipe. Installed Open GApps and then magisk, and then rebooted into the system.

Everything seems to work, except that Magisk reports both parts of SafetyNet as failing, and an App like Netflix is incompatible with the device. This was fine on previous build, where Netflix worked fine.

I'm on T810. Anyone else experiencing the same?
[Galaxy Tab S2 Android Development] mr-br:
It works fine for my T815. The camera button is truncated at the bottom though (minor nit).

LOS seems much snappier than stock 7.0 which was getting annoyingly sluggish (>10s to display the BT menu). Admittedly I hadn't reset it for a while but I wanted to give LOS another whirl after a couple of years back with 7.1.2 when SDcard access, BT and fingerprint issues put me right off.

However it took me a while to get it booted since it would stay on the animated boot logo for ages, then it would go dim and then reboot into TWRP.

This was a new install from stock. I was wiping and formatting as per the process. Eventually I found that gapps was causing an issue ( I wasn't using addonsu) since just it booted OK by flashing LOS alone (lineage-16.0-20200419-UNOFFICIAL-gts210ltexx).

Eventually I managed to get it to boot successfully by flashing LOS alone, booting then doing a factory reset in TWRP and flashing gapps nano 9.0 20200422 (not installing TWRP).

The whole thing seemed rather random though as I was sure that I'd tried that combo before, so maybe something is flaky. I have the gapps debug logs but no idea where to post them.

Other aspects so far:

Fingerprint scanner generally seems to work, though if I have to wake the screen by pressing the home or power keys, sometimes the fingerprint doesn't work. It shows a fingerprint icon and after pressing that it says I have to manually unlock or it shows the pattern. Stock unlocks with the fingerprint every time or else says "No match". Bit of a shame it isn't working properly after all this time.

BT speaker works fine.

Battery seems to drain quicker than stock but I've not looked into it yet.

The capacitive Back and Recent buttons never light up, but the "Samsung Button Light" app at least gives a vibrate option.

Also I can't find an option to display the icon labels for the favourites bar. Maybe time to try another launcher.
[Galaxy Tab S2 Android Development] sal82:
Had the same problem on my T810. Unchecking "install TWRP as a system app" after you install LOS should make the tablet boot up.
[Galaxy Tab S2 Android Development] aljazzair:
Thank you for this ROM.

The installation process was quite convoluted, but I finally have managed to do it on my T815C.

One issue, apart from what is already known:

LTE Signal data is not working. It is giving a constant reading for RSRP /RSSNR with different numbers in different apps.

When I was running stock I used a nice app called Network Cell info, as well as others to position my tablet in a way that maximizes signal.

It is no longer possible due to unreliable readings.

Is there something we can do about it?
[Galaxy Tab S2 Android Development] dannychow:
Thanks for your reply. I finally found that my front camera has hardware issue but not due to the ROM.
