Sorry for the delay, you know how much fun wiping a tablet is... So I never came across this bug originally as my tablet has always been encrypted. However I did format data, booted into LOS, and my tablet reported as being Not Encrypted. I then hit Encrypt tablet. As [MENTION=8175453]Akipe[/MENTION] said, the tablet does power off rather than reboot, but when power back on it does encrypt now. If the encryption key is not entered, no data can be accessed. In LOS it says encrypted. Best I can tell all is working normally now?

Here recently Codeworkx released a version of TWRP for the OnePlus 5T that if encrypted requires the password to be entered: Latest version here. Kind of a "security" measure as you can't just hit cancel and wipe the device without the password. Yes there are ways around it, but keeps the average person out of things they shouldn't be in. Could be a neat feature to have on the wish list.

Of Course, it's just nice to have an up to date working TWRP now, huge thanks to [MENTION=8175453]Akipe[/MENTION]. Of course not forgetting all the work [MENTION=5075128]LuK1337[/MENTION] has put into our tablet either.

My TWRP 3.3.1-0 from the android-6.0 branch

twrp-3.3.1-0-gts210vewifi.img

twrp-3.3.1-0-gts210vewifi.tar

I used the official android-6.0 branch to build this, as this branch has cryptfs support and was used to build pre-3.2 TWRPs. Maybe this will help with the decryption issue?

Latest T813 bootloader

T813XXS2BSJ3.tar
[Galaxy Tab S2 Original Android Development] Berend de Boer:
I've tried to flash this on my pretty much stock SM-T813 which has Android 7:

./heimdall flash --RECOVERY ~/Downloads/twrp-3.3.1-0-gts210vewifi.img --no-reboot

This appears to work initially, white progress bar goes to max, and heimdall finishes without errors. Then nothing happens, screen keeps saying do not reboot. When I run out of patience, and reboot and go to recovery, I first get "installing system update...", then a falling down Android image with ""no command". When I boot into recovery, I still have the Samsung recovery.

What am I doing wrong?
[Galaxy Tab S2 Original Android Development] Berend de Boer:
OK, what happens as explained to me on the #twrp challel is that the system ROM flashes back the recovery. So after flashing the recovery, I needed to boot into TWRP straight-away. You do that by unplugging the USB cable, then exiting download mode by pressing Home + Volume Down + Power, and as soon as it exits (the black screen comes up), you switch your finger to the Volume Up, while keeping Home + Power down, then it boots straight into TWRP recovery, and TWRP will offer to make the change to your system partition so this does not happen in the future.

You will also see a new yellow message on the screen: "Set Warranty Bit: recovery". I suggest this gets added to the install instructions. I had seen some posts to this effect, but it wasn't entirely clear to me what was going on, and initially I had some trouble booting straight back into recovery out of download mode.

How to flash the .img file to SM-T813

I have been trying to convert the twrp-3.3.1-BETA07-gts210vewifi.img file to twrp-3.3.1-BETA07-gts210vewifi.tar.md5 without success. How are you guys flashing this onto the SM-T813? Heimdall needs Heimdall packaged files and Odin/Jodin needs a recovery.tar.md5 file. A "How To" would have been very kind of someone. Any help would be greatly appreciated. I use both Linux and Windows PCs.... :o
[Galaxy Tab S2 Original Android Development] TKruzze:
Easiest method is to simply flash the TWRP you want from whatever TWRP you have installed. Use the flash image (recovery) option to flash.
[Galaxy Tab S2 Original Android Development] mynameis123:
Thanks for your suggestion...

My device is not rooted, I don't think I'll be able to do that without root. I do not get the option that says 'Select a file to flash..' in the official TWRP App. It's very difficult getting reliable (working) information on rooting and installing recovery and custom ROMS for the SM-T813. Odin, jOdin and Heimdall all seem to not work for me. My device is still vanilla, unmodified in any way :(
[Galaxy Tab S2 Original Android Development] MrCsabaToth:
Can someone help me to determine which SM-T813 do I have? The serial number is R52K3111SGF, when I register that at Samsung it yields Model Number SM-T813NZKSXAR. However I don't know which TWRP I should install: "Samsung Galaxy Tab S2 9.7 2015 (Wi-Fi) (gts210wifi)" or "Samsung Galaxy Tab S2 9.7 WiFi (2016) (gts210vewifi)". Furthermore I don't know which ROM I need to get or where can I get the latest ROM.

I live in the US and sites I visited offered Turkish and all other ROMs except US. This is a wifi model so not sure if the "Carrier" matters or relevant at all thought. The device does not boot, but I can get it to download mode. I want to flash the TWRP and if it doesn't boot after that then a ROM as well. I just want to get it to work. Thanks!
[Galaxy Tab S2 Original Android Development] ripee:
You can get a rom for your tablet in this subforum. It mixes the 2015 and 2016 variants because they are both the Tab S2, just different generations.

Your tablet is the gts210vewifi. Flash the twrp and roms that correspond to that. You don't need to concern yourself with any carrier because your tablet is a wifi-only variant, it has no SIM card slot.

Boot into Download mode and flash the latest twrp .tar file from TeamWin's official site, using Odin if you have Windows, or Heimdall if you have Linux.

TWRP 3.4.0 has been released

... and cannot decrypt the data partition. Back at 3.2.3 again.
[Galaxy Tab S2 Original Android Development] ripee:
I will run my own build later today from the older source branch. See my google drive later, perhaps the older source will be able to decrypt it.
[Galaxy Tab S2 Original Android Development] rogers11:
Thanks, but why is this necessary? Is the whole thing published untested on the TWRP site?
[Galaxy Tab S2 Original Android Development] ripee:
Actually, I was mistaken in my explanation. TeamWin's build servers use the latest source branch that is able to be built. Because the official Nougat branch fails due to the forced HW encryption, it refers back to the Marshmallow branch, which builds fine. This is where the official build cones from.

However, this branch suffers from bugs of its own, such as no usb access while in twrp, which does not affect the Nougat branch.

My single modification to the Nougat branch is the removal of the forced HW encryption, which allows it to build as expected. I designate this change with the "-1" version number at the end.
[Galaxy Tab S2 Original Android Development] rogers11:
Hello, your 3.4.0 version also isn't able to decrypt /data. It cannot find the encryption footer. What's wrong with my device?
[Galaxy Tab S2 Original Android Development] Techguy777:
I tried the official TWRP 3.4 and what a train wreck. I dont encrypt/decrypt anything but I made a back with android 9 pie aosip rom and tried lineage 17.1 to see how it works. So far pretty good but since the tablet is my dads I make sure hes on a stable rom without problems. SO I wiped and tried restoring backup I made of Pie and it completes and says NO Os do you still want to reboot? So I reflashed the AOSIP zip on top of the data like I do on my Nexus 6 and it works but when you load up the rom its nothing but problems everything is crashing and play store keeps stopping. I had to reinstall 3.3.1 and restore from that which worked like normal. I dont know what is wrong with TWRP 3.4 its all messed up. I didnt see this one until today but Im sure theres bugs .

---------- Post added at 05:45 PM ---------- Previous post was at 05:42 PM ----------

Have your tried your TWRP 3.4.0.1? I ask because the official is a disature for this tablet right now. Someone needs to try to backup and restore their tablet with it.
[Galaxy Tab S2 Original Android Development] ripee:
Perhaps TeamWin released 3.4 too recklessly. I expect there to be a 3.4.1 soon enough if these bugs keep adding up across a number of devices, but I have no definitive information about future TWRP versions.

[Galaxy Tab S2 Original Android Development] Uliaoth:
I have a little question.

I followed the guide from this subject https://xdaforums.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627

I managed to flash the latest TWRP with Odin. But twrp won't flash the "boot image file" provided in the linked topic. Then I flashed magisk and everything seemed OK. The tablet is rooted (smt-813) and I successfully created a backup.

My question is the following. Can I install a custom ROM like LOS without any risk of brick ?

Thanks in advance.
[Galaxy Tab S2 Original Android Development] RJRobb:
Anytime you introduce new software or ROM there is the risk of bricking. As long as you can get into recovery (TWRP) or bootloader (ODIN) it can be fixed. This is why you want to create backups! I've flipped back and forth between OEM and LINEAGEOS several times without issue. Disabling encryption also IMO reduces the risk of problems.
[Galaxy Tab S2 Original Android Development] RJRobb:
Which one should I be using?

The twrp 3.3.1-beta 7 by akipe android 9 branch?

-or- twrp 3.4.0-1 by ripee android 7.1 branch

[Galaxy Tab S2 Original Android Development] rogers11:
Good morning, i had to reset my device with LOS 16. It was encrypted and i used TWRP 3.2.3 because no newer version was able to decrypt the data partition.

After the reset i installed TWRP 3.5.2 but this one isnt't even able to encrypt the device. I get the green android and some seconds later I'm back at the lockscreen. What is wrong?

Should i go with 3.2.3 again?
[Galaxy Tab S2 Original Android Development] Techguy777:
Most people that root don't want encryption so I'm not sure what you should do. Try going back but I would recommend just not encrypting.
[Galaxy Tab S2 Original Android Development] rogers11:
All my devices are rooted and encrypted. I do not have any problems with them. It's just the tablet that makes trouble.
[LeEco Le Max 2 Themes, Apps, and Mods] kanagawaben:
I am running MoKee with pretty decent battery life but am currently experimenting with reducing screen resolution and tweaking CPU & GPU settings (using Kernel Aduitor) to see if I can squeeze more out of a charge. Not really sure what the best settings are to maximise battery while keeping smooth everyday performance (I don't game or do any very heavy tasks or multitasking). I thought that it might be possible to get near SD625 stamina from the SD820 seeing as they are both built on the 14nm process, but the architecture is very different (ours has the quad-core big little set up with kryo, as opposed to the 625's octa-core A53 set up). At the moment I am trying it with the little cores left at default and the big cores max frequency down clocked by about 25%. I haven't changed the governors. I also down clocked the GPU max frequency a bit. Anyone have any advice regarding an optimal set up?
[LeEco Le Max 2 Themes, Apps, and Mods] valy_cta:
Not sure about the best settings but for sure I'm waiting for your feedback regarding this change and battery life. It should be improving it, but nobody knows how much.

Also I've noticed that in youtube if there is 720p or 1080p, the default setting is 720p (of course our screen is a multiple of 720p).

Are the pixels visible?
[LeEco Le Max 2 Themes, Apps, and Mods] kanagawaben:
Couldn't see pixels with reduced screen resolution, even at 720p. Of course it's only rendering a lower resolution image then stretching it over the physical

1440p display. The result is just a softer image. Looks a bit strange, but 1080p wasn't too bad. However, didn't seem to have any effect on battery life and surprisingly at 720p I got a worse Antutu score than normal, so I have given up and returned to 2K.
[LeEco Le Max 2 Themes, Apps, and Mods] valy_cta:
I feel sorry for that :( I was really hoping for some way to increase the battery life a bit.
[LeEco Le Max 2 Themes, Apps, and Mods] Lizard82:
Hey guys... Today I found something interesting in our German Android forum. There's a group of people who are developing a great Rom for our device. It's just called the telegram Rom.

So the Rom will include scripts tweaks and a full working app for changing governors. So you will be able to get a much better battery life. The German guys talking about 20 to 30 percent extra power for our device.

The hole project behind this was founded here on xda but mainly developed for the Oneplus-3.

But in fact the whole workaround is working on any device that's running a SD820 processor.

Here is the link to the site

https://xdaforums.com/oneplus-3/how-to/advanced-interactive-governor-tweaks-t3476589

So maybe you like to have a look. There are also complete explanations of how the SD820 works related to energy management and voltage at minimal and maximum clock speed!

I hope this can answer your questions.
[LeEco Le Max 2 Themes, Apps, and Mods] blanktape:
Thanks for sharing Lizard82.

I follow the thread and use AKT... i am using the profile called Project Zhana & X.A.N.A v4.2. 14 hr sot is unheard of but I am getting close to 6hrs sot with xposed loaded which I am already impressed. It is is way better then what I used to get around 3 hrs sot. I am running revolution 21s rom which is very similar to EUI and not the most optimized rom with heavy battery drain. and I am happy that this phone finally has a good battery life. Appreciate Lizard82.
[LeEco Le Max 2 Themes, Apps, and Mods] Slay1991:
The sot really depends of what you do with the phone, and what apps run when the phone is on idle. I changed the resolution to 1080p but didn't notice any difference, so I went back to 1440p. There are tons of threads about kernel Adiutor, you won't have a hard time finding it
[LeEco Le Max 2 Themes, Apps, and Mods] Moon75:
For best battery on Nougat I did this on Nexus 7.1 and AOSP 7.1 roms with BS kernel:

- Use rom that can use Black Screen kernel 2.1/2.2 or later

- Use kernel Adiutor to change CPU governor to impulse (or Darkness)

- Set value in Govenor tuneable (locate just under CPU Governor touch it to go inside to change value) : highspeed_freq to 307200, set Powersave_Bias to 1. I changed both BIG and LITTLE CPU core in kernel Adiutor.

- I think keep AKT profile on stock/unchange no need to set it is ok

[Asus ZenWatch 3] blackhand64:
Hi everyone, as you should know the Asus Zenwatch 3 has an AMOLED display. From my understanding this should mean when displaying the colour black, the pixels should be turned off completely (like on my S7 Edge).

I was looking at my watch in a pitch black room with an ambient watch face displaying a black background and it appeared slightly reddish. Compared with my LG G Watch R sporting the exact same watch face it was clear the LG had the black pixels turned off but not on my Zenwatch 3.

I've attached a couple of pictures taken with my phone of the Zenwatch 3 in a pitch black room, one with normal shutter speed and the other with a 2 second shutter speed. Evidently the 2 second shutter speed shows that the display is in fact not turning off the pixels. The pics were taken when the watch was charging and in ambient mode with a watch face set to true black only.

Can anyone else confirm that this is the case and maybe a reason why? I'm worried that battery life may be affected by this with always on display enabled.

Lastly on a side note, are the black lines that aren't illuminated something to worry about?
[Asus ZenWatch 3] frelnik:
Mine is the same, including a similar set of dark lines. I've seen others on Reddit report identical concerns.
[Asus ZenWatch 3] 850T5m:
Noticed this too, thought I was crazy lol...kinda waste of an AMOLED screen.
[Asus ZenWatch 3] blackhand64:
Hmmm ok at least I'm not the only one. Hopefully Asus is able to change it in a future update.
[Asus ZenWatch 3] reojo:
Yeah it is weird, black watch faces aren't truly black. I think they did it so watch faces can blend into the color scheme of the watch, if you notice the color overlay on the app launcher
[Asus ZenWatch 3] deathgame:
That's because of auto Brightness. Turn it off. This impacts battery life. I observed this on very first day after the purchase. Using manual Brightness since then.
[Asus ZenWatch 3] blackhand64:
I just tried disabling Auto Brightness but the red tinge of the black background still exists.
[Asus ZenWatch 3] deathgame:
It doesn't happen with me. If I turn off auto Brightness the blacks go complete black. Do you have live display turned on your phones? If so try disabling it. May be this setting depends on your phone. All I can confirm is if I turned auto Brightness off amoled works perfectly.
[Asus ZenWatch 3] blackhand64:
Not sure what you mean by live display but I just have a stock S7 Edge. I prefer keeping the auto brightness on for my watch so I guess I'll have to live with it.
[Asus ZenWatch 3] reojo:
Live display is when some ROMs allow the screen to have a tint at night time so the blue light from the screen won't affect your eyes at night
[Asus ZenWatch 3] harlin73:
Me too have similar display and black line like that.

Glad I'm not the only one with this condition.

Turning off the auto brightness is not a solution. Its a pain if you had to adjust the brightness all the time

Below the original is a response I received.

Hi Im not a developer and dont know much about android i just don't know who to ask for this particular problem.

I had a ZTE Obsidian phone that wont get past the Metropcs boot screen so I did a system restore menu by holding power and the up vol button.

After going to boot menu I created a backup to my sdcard. userdata_20150101_003623.backup this is the file name I was given. To make sure I created another one and the only diffrence is trhe file extension saying backup1.

I then factory reset the phone and tried to reboot but it still has the same problem. I purchased a new phone the asus Zenfone3. I then tried to do the same thing here but restore the phone using the same backup from the ZTE but I received an error saying the backup is out of date. The zte was running on lollipop and the asus on marshmellow.

Im on windows 10. I was hoping to find away to extract my contacts and possibly the app color note with the notes I wrote in it from the backup.

Is this possible can I extract these files from a .backup to my windows 10 desktop some kind of way or can I get another zte phone and create a clone of my last one from the backup file

Greetings and welcome to assist. Do you know what format the backup was saved in ? Where you using twrp or cwm? You could use titanium backup to extract from the backup on your phone if you have root or I think assayed kitchen has the option to extract from a back up here

Do you know what format the backup was saved in ?

No I dont know what format the file is saved in. The file extension just says .backup

Where you using twrp or cwm?

Im a novice at android and developing. I dont know what these are. I used my no rooted phone from Metro Pcs (ZTE Obsidian Z820) before I factory rest it I created a backup using the factory restore system on the phone. I did not use a computer or third party apps to do this.

You could use titanium backup to extract from the backup on your phone if you have root or I think assayed kitchen has the option to extract from a back up here.

The phone was from metro pcs and not rooted. I have also downloaded the (Assayed Kitchen) program but have no idea how to use it to access the .backup file. There are no instructions for some one of my limited knowledge on android phones.
[XDA Assist] sawdoctor:
Greetings ans welcome again. It is unusual for a stock recovery to be able to make a back up that is the problem, it is only normally possible to make a backup using a custom recovery like cwm or twrp so I assumed you had done this. You can not restore a backup from a different model of phone as it is incompatible, if you copy your back up to your pc and right click it to get properties it should tell you what file extension was used. You won't be able to restore the back up to a different model of phone but may be able to extract contacts, messages, photos etc

[XDA Assist] JollyDangerous:
Yea thats what I thought but wanted to verify it. Im currently trying to find the same model phone online so I can use the files.

When I click the properties button the file type is listed as "BACKUP (.backup)". I dont think there is a program that can actually read this file type at least I cant find one that does.

If there is one I would like to be able to get that kind of info off of it.
