Australia got much different laws on WIFI frequency, I will do a T813 rom for Australia. It will be available in about 1 hour on main page ;)
[Galaxy Tab S2 Android Development] teeedubb:
Hi Svan987,

Thanks for providing a build so quickly. Unfortunately I have the same issue after flashing the AU version of your rom. In both the wifi portion of the initial setup and the wifi settings in the rom, wifi will turn on for approx 5 seconds and then turn off automatically.

I can provide any for of logging you want, youll just need to tell what files as I am not that familiar with the underbelly of Android.

Well, I discovered that restoring a back up with compression enabled, it will fail. I tried not enabling it and it succeeded. About the shareit app file transfer it sends a file but cannot receive one. What I did was send a small file from t813. Then without disconnecting the other tablet I send a file to t813 and it works. By the way I'm still in v1. This is without the WiFi direct and hotspot zip flashed.

About the WiFi direct and hotspot zip which I tried to flash, it resulted to popping out of "nearby services stopped" and "WiFi direct stopped". I did a wipe dalvic and cache after flashing. Maybe because it is based on XAR I don't know.

I want to update to v3 from v1. I don't know what to download. My country is Philippines (T813 is not available in the Phils)

but my tab s2 is made in Korea and the firmware installed is from Malaysia. Right now my WiFi is OK with v1 with APK6 MALAYSIA OR Indonesia as base firmware.

What is the proper way of updating from version to another version via twrp?

Sorry for the long message. Maybe this can also help and inform other users of stock lite.

Thank u! Cheers!

Took the plunge yesterday afternoon and I rooted, installed TWRP and flashed this ROM. So far I am very pleased with the performance and battery life. Good job! :good::good::good::good::good:
[Galaxy Tab S2 Android Development] Svan987:
Need to know wich official firmware you flashed to go to PDA APK6 because the last official firmware from Hong Kong has PDA APJ2. So normally you shouldn't flash my rom (It's in requirements on main page).

After there is a CSC change that you can do but I am not a specialist in that. CSC regroup informations about PDA + Modem. PDA is the heart of a rom and modem manage WIFI and bluetooth in our models.

Normally you can go back to official PDA APJ2 with Odin flash. If you decide to do that I will do the rom on your PDA APJ2. Search infos on the web about downgrading firmware to be sure that it will not brick your tablet. I can try to help you, just send me private message will be easier for everybody as your case is very special.

Cheers.
[Galaxy Tab S2 Android Development] Svan987:
Hi,

I found only a Singapore (XSP) firmware on the web. with PDA APK6. The best you can do now is to install Phone INFO from Google Play and check CSC page to get infos.

(If you can save info from the app and post the file gonna be great too). If can not just write all CSC infos.

Cheers.
[Galaxy Tab S2 Android Development] Svan987:
Heya thanx for the feedback always appreciate it :D

I tried updating from v1 to v3. It is working good. Wifi seems ok flashing with EU v3 on KOO CSC Korean made T813 as phone info is telling.

Will report back any observations on this updated version: v3.

CHEERS!
[Galaxy Tab S2 Android Development] Svan987:
Hi, your are in similar case like [MENTION=3044638]teeedubb[/MENTION]. Last official firmware for Korea is a PDA APJ1. You shouldn't flash my rom too :eek:

If you decide to go back to this last official firmware, just send me a private message and I will do the rom for this PDA.

I discovered that "system/app/WfdBroker" is connected to "WIFI-Direct - Allshare" so I will update TWRP files package.

Cheers.

[Galaxy Tab S2 Android Development] FitzWM:
Hey, great ROM, loving the de-bloating and the battery improvements. A problem, though: I've installed the correct (US) version of v4, but I'm still unable to connect to 5 GHz networks. As my 2.4 GHz network can't really handle high-quality media streaming, I really need that to work. Do I need to install the WiFI Direct fix on v4, or do I need to do something else? Again, thanks for the ROM.
[Galaxy Tab S2 Android Development] Svan987:
Hi,

"Wifi-Direct" is not a fix. It's system files to use "Wifi-Direct" that let you connect directly to others devices using Wifi and let you share and transfer files.

Is it a tablet bought in US and wich model ? Wich official firmware did you have before installing the custom rom ? Can you connect to 5 Ghz wifi on your last official firmware ?

If you can install "Phone INFO" from Google Play and screenshoot or write infos from "CSC" page can help too.

Cheers.
[Galaxy Tab S2 Android Development] pastorbob62:
I am unable to do a backup from TWRP because it says it cannot mount the /data partition. I assume it is related to the encryption issues. So how do I fix it so I can back up???

UPDATE: WTF?? I wound up having to go through the entire flash procedure to get back to a working tablet. And all I did was boot into TWRP to do a backup. The first clue that something was amiss was when I was unable to do a backup from TWRP because it said it couldn't mount the /data partition. Kind of odd to say the least.
[Galaxy Tab S2 Android Development] FitzWM:
Thanks for the quick reply!

Yes, the tablet was bought in the US, though it was a used model, so I suppose it could have come from somewhere else. The General page of Phone Info lists the Country of Origin as Vietnam, if that matters. My last official firmware was T813XXU2APK6_T813XAR2APK6_XAR from SamMobile, which seemed to work fine for the brief period I had it installed.

Yes, I could - rooted and unrooted.

I already had it installed, but the only thing that comes up on the CSC page is the Original CSC Code, XAR.

Hope that helps.
[Galaxy Tab S2 Android Development] Svan987:
Follow instructions on main page and everthing gonna be fine. Have tips for update too on post #2.
[Galaxy Tab S2 Android Development] Svan987:
I don't know what to say really. All the files are original US firmware untouched (except SuperSU and busybox). Did you install earlier version than v4 ? Do you have 1 SSID or 2 ? Try forget the network and reboot to TWRP and wipe cache/dalvik cache. Switch off - on your router and try again. Can use WIFI manager on google play too. [MENTION=7906962]gm8599[/MENTION] reported it was working well on both frequencies.
[Galaxy Tab S2 Android Development] pastorbob62:
Getting back to a working tablet wasn't a problem, as I said in my post. My question is why did I have to do it in the first place? Probably not even related to the ROM at all but rather a quirk on my SDcard. But apparently it's an answer I will have to live without.
[Galaxy Tab S2 Android Development] pastorbob62:
Same crap, different time. I was able to do a TWRP backup after formatting /data, doing a wipe and reinstalling version 3 of the ROM. However, I went in later to try to do an updated backup after installing all of my apps and I got the same error message, "unable to mount /data - invalid argument". It didn't matter what I did I still got the error message. I just tried to flash version 4 and have been staring at the SAMSUNG logo blinking at me for the past five minutes. Before I am bombed with a lot of questions, yes I did follow the instructions as given on the first post to a T.

I am ready to go back to full stock since I didn't see these issues with it. Also not able to connect to the 5 Ghz WIFI. I was able to connect to it on stock.

Too many quirky issues cropping up to continue using this ROM as daily driver. :(
[Galaxy Tab S2 Android Development] Svan987:
Can you explain me why I dont get any mount partition trouble on my T813 ? I can do backups and restore any partition. It's working 100%. For wifi 5 ghz it's another story and samsung not helping on wifi advanced settings. Go complain on TWRP post if you get trouble with it.
[Galaxy Tab S2 Android Development] pastorbob62:
No I can't. I didn't mean to offend or imply your ROM is at fault. I was just a little frustrated after doing complete wipe/install/update three times and still running into the issue.

I must be doing something between the initial installation/successful TWRP backup and when TWRP cannot mount the /data partition. Whether it is an app I am installing, a configuration setting, or the way I am booting into recovery, something is different.

As it now stands, I am back to stock with everything working properly. I am going to give it a few days and then try again. I don't stream video very often so the 5 Ghz issue is not a deal breaker. But, I have no doubt it will be fixed eventually.

Keep up the good work! ;)

UPDATE: I figured it out!!! I didn't realize the rooting was included in your ROM so I was flashing SU 2.78 SR3 after flashing the ROM. Apparently that was screwing up something in the data partition so after a reboot and SU was completely installed I couldn't access the partition from TWRP. So I have been on your ROM the past 12 hours with everything working as it should. (Except 5 Ghz WIFI).
[Galaxy Tab S2 Android Development] Svan987:
Great happy that you fixed data partition. There is a trick you can do to avoid loosing to much time too is at first boot you install "DiskInfo" on Google Play and you click "Data" partition and if it's written "Encrypted" you did something wrong then you have to restart installation. For WIFI : how many SSID you have ? You can try use "WIFI Manager" on Google Play and test. The best I think is when you use 2 SSID on your router. One dedicated to 5 ghz and the other one to 2.4 ghz, but remember that 5 ghz signal is weaker than 2,4 ghz. What you can try also is to change 5 ghz channel on the router can help sometime. One thing you can do also is to switch off router then on again to refresh everything. Hope can get more people reporting same, because got one with T713 US reported that all bands were working.
[Galaxy Tab S2 Android Development] pastorbob62:
My router and AP both have separate SSID's for 2.4 Ghz and 5Ghz. And, as I stated previously, they both worked just fine on pure stock with great signal strength. Our phones both show the 5 Ghz band with good signals too. I will try rebooting them both. It isn't a big deal since my throughput on 2.4 Ghz is good.

Thanks for the tips. :good:
[Galaxy Tab S2 Android Development] Svan987:
I will create the same rom without SuperSU and without busybox. Can you test it with Wifi 5 ghz and give feedback ? If yes will send you the link by private message.

(There is 2 possibilities : when exctracting the official rom something happenning in files (I doubt). When root and busybox are installed they are breaking something.

Cheers.
[Galaxy Tab S2 Android Development] pastorbob62:
Sure, I would be happy to give it a test for you. It will probably be tomorrow before I get it done. :good:

hi

i have a problem with wifi

i'm in switzerland and i flashed the stock lite v4 (EU) version

now after that i select language and i want to turn on the wifi, it automatically turns off again

what can i do?
[Galaxy Tab S2 Android Development] Svan987:
Hi,

Can you confirm that before flashing you were on official swiss PDA APK6 ? Wich tablet model you have and did you buy it in switzerland ?

I will start to do the roms on swiss base. You will find download on main page tomorrow afternoon.

Cheers.
[Galaxy Tab S2 Android Development] dome8802:
I don't know if i had PDA APK6

I have a t813 and bought it in switzerland
[Galaxy Tab S2 Android Development] Svan987:
You should read the requirements part before flashing a rom. I recommand that you go back to full stock with Odin (PDA : T813XXU2APK6 - CSC : T813AUT2APL1).

Reinstall TWRP then do a backup of "system" and flash again the Stock Lite rom. Will wait on your feedback if need to do a custom rom for switzerland.

Cheers.

Install the Wifi Fix from here
[Galaxy Tab S2 Android Development] ttalonso:
Hi. I have wifi problems and others with this ROM. I reflash original ROM with odin, and start all the steps. Now,wifi and all work perfect (automatic in dhcp, :)... all except GPS :( .

Maps and other programs not positioning me. Say GPS is not available at this moment. any idea?
[Galaxy Tab S2 Android Development] waterpolo:
I used GPS status app from playstore which is working fine.

You must stay outside to detect the GPS satellites.
[Galaxy Tab S2 Android Development] ttalonso:
I restore all. And now works all fine. :)

One more question. It's possible to install samsung weather widget?
[Galaxy Tab S2 Android Development] Beyaz66:
Hi [MENTION=5767828]Svan987[/MENTION] , thanks for your efforts.

I've tried 3 times but there's nothing I can do: wifi direct keep crashing at startup and when used.

(I've also noticed some minor root authorization errors when "automatically allow access" is activated in settings)

Here's my third and last try's detailed steps :

XAR (default) > XEF > TWRP 3.0.2-1 (via Odin) > TWRP 3.0.3-2 (through twrp) > no-verity-no-encrypt_ashyx

> T713XXU2APK6_Stock_Lite_v4_(EU) > T713XXU2APK6_Wifi-Direct_v2_(EU) > no-verity-no-encrypt_ashyx > Cache & Dalvik clear > Reboot

My thirst installation was : XAR (default) > TWRP 3.0.2-1 (via Odin) > TWRP 3.0.3-2 (through twrp) > T713XXU2APK6_Stock_Lite_v4_(EU) > no-verity-no-encrypt_ashyx > T713XXU2APK6_Wifi-Direct_v2_(EU) > no-verity-no-encrypt_ashyx > Cache & Dalvik clear > Reboot

I don't remember the second one's steps

There are screenshots from Phone Info for stock XAR rom (XEF rom's CSC was also good) and your rom (where 'CSC version' in firmware infos is missing, and nothing on csc code panel) in attachements.

Where am I wrong?

Also, is there any chance that you build a flashable package with theese apps ? :

system/app/BeaconManager_40 (Battery manager for Bluetooth) Android Beacon Library

system/app/QuickConnect_40 (Samsung Quick Connect)

system/priv-app/com.qualcomm.location

system/priv-app/xtra_t_app (Qualcomm enhanced location)

system/priv-app/Hearingdro_Tablet_V4M (Adapt sound)

system/priv-app/SoundAlive_Tablet_30_M (SoundAlive)

Thanks again.
[Galaxy Tab S2 Android Development] Svan987:
Reinstall those files from uploaded "Packages removed" and check files permissions then reboot :

system/app/Weather2016

system/app/WeatherWidget2016

Hi,

You don't need to flash 2 times "no-verity-no-encrypt_ashyx". Just one time after the custom rom flash.

Hope you are doing a "Factory Reset" because it's not written.

If you tell me wich world aera you bought your tablet and wich firmware was on it at the beginning can help.

(Seems you changed US CSC code to EU CSC)

I uploaded "Packages removed" archive so you can add what you need later on (check files persmissions then reboot)

system/app/QuickConnect_40 ----> reinstall this too ----> system/etc/permissions/com.sec.feature.findo.xml

(update your TWRP to 3.0.3-5)

Hi all

I flashed today this rom to my tab s2 t813 and it work alomst well....

But, Titanium cant find the root permission .

Other apps like AfWall works fine , but titanium tells me, the root permission is not given, but i gave it..

OK, anybody a solution for that.?

Second, I would like to use xpose and xprivcey. Anybody has got it working this combination?

Thanks for reading and helping!

Greetings ivi

[Galaxy Tab S2 Android Development] Svan987:
Hi, just tested Titanium Backup 7.6.1. At first start was asked to grant access for SuperSU. Working 100% tested "Clean up the dalvik cache". Personally never used XPrivacy so I can not help on that.

Cheers.
[Galaxy Tab S2 Android Development] ivifly:
Thank you Svan!

You right, finally my Titanium is to old and can't run on android 6.0.1.

But, I installed xposed, and it works fine. Also xprivcey.

Question, I need the exchange email apk that was made for this device t813.

How can I reinstall that.?

Thank for your helpfool work!

Greetings ivi
[Galaxy Tab S2 Android Development] Svan987:
Just reinstall the package "system/priv-app/SecEmail_M" then check permissions and reboot. Cheers.
[Galaxy Tab S2 Android Development] Beyaz66:
Thanks for the info' about TWRP 3.0.3-5. But I should have precised earlier: I have a T713.

Yes, factory reset,system/data/cache/dalvik wipe was done.

I can't guaranty in which world area it was at first. I've received it frp locked from a seller located in the US and only have seen XAR csc applying in the stock samsung recovery's log. Plus, prodcode.dat file in efs\imei folder shows SM-T713NZKEXAR (with every rom).

As you mentionned "Please download and flash the right world aera version to avoid wifi connection problems !", I thought that we have to install the right world area version of your rom according to the latest one installed on the device and to the area in which the device is desired to be used.

But you mean that I have to begin with a stock rom with xar csc -like it was released by the manufacturer- even if I will use it in France. Is that? --And will this trigger the 'impossible to see or connect to WIFI 5 ghz networks' problem in my location?!?!--

So simply, that I have done is :

> starting from scratch and a fresh stock XAR rom (with no reboot after the flash)

> official TWRP 3.0.3-2 (I've attached an odin flashable package to this post as there is none in the official thread nor in twrp's website) (reboot to recovery)

> Stock Lite US (and not EU) (no reboot)

> Wifi-Direct v2 US (no reboot)

> no-verity-no-encrypt_ashyx

> Cache & Dalvik clear (just for fun)

> Boot

====> And this gives me the same wifi-direct crash.

> I've also tried : XAR rom > Boot > flash twrp 3.0.3-2 > reboot recovery > data wipe with "yes" confirmation > reboot recovery > factory reset with swipe > install your US rom + no-verity-no-encrypt > reboot. That's ok.

> But as soon as I install the Wifi-Direct v2 US + Dalvik/Art&Cash clear, I keep having the crash at system boot and/or every time I reactivate the wifi.

Both of these only show the "Original CSC Code : XAR" in Phone INFO app from your rom.

I don't understand what I forget to do or what I do wrong. There's no reason why this doesn't work for me while it does for others. Could any log help you? I really want to stay on this lightened stock rom but I can't do without some of the functionalities.

I'm sorry for the inconvenience :) and thanks you and anyone who could help us in advance.

Did you configured supersu to automatically allow root access?
[Galaxy Tab S2 Android Development] Svan987:
Hi Beyaz,

First you have to be sure that the model you are using is T713 exactly. Second you have to flash original stock US APK6 (Need to check if it's support Multi-CSC). If you gonna use the tablet most of the time in France (Europe) then you have to switch CSC to XEF.

When your CSC is XEF you gonna flash the original french stock rom APK6 (Test wifi so you sure that it's working). And only at this moment you can start flash and use Stock Lite (EU).

(XEF is an example. You have to check wich CSC are available)

Do you know that "Wifi-Direct" is not a fix ? It's system files to use "Wifi-Direct" that let you connect directly to others devices using Wifi and let you share and transfer files. If you need that functionality and It's still not working after you did the right steps tell it to me again I will do more testing.
[Galaxy Tab S2 Android Development] cajunj:
WiFI issues

OK so i will apologize and say i am new to dealing with Samsung however this one was free so i will not complain. I flashed you rom per the instructions and everything seemed to go well except the WiFi will not come on at all. Unfortunately i made the noobmistake and didnt make a backup of the original Rom so i am kinda left with it useless. it is a Samsung SM-t713 and the person said they bought it off of amazon.

Note i used Stock Lite V4 US

any help would be great
[Galaxy Tab S2 Android Development] Svan987:
You will need to go to settings "Lock screen and security" and check that "Uknown sources" is switched "ON". Then you have to find "Phone Info 3.5.1" apk on the web (Don't use 3.5.2 it's require internet).

Transfer the apk to your tablet and install it. Check what you get on CSC Code tab (Original CSC Code).
[Galaxy Tab S2 Android Development] Beyaz66:
:D Yes I do know what wifi direct is.

And it's exactly what I did ! The device is a T713NZDEXAR 》Official stock APK6 XAR (I can't find a multi csc version!) 》Offcial stock APK6 XEF (2 times with some cleans to ensure that the XEF csc is set as the default, I've found this trick somewhere in xda) 》Your ROM = no csc + Wifi Direct = wifi direct crashes.

Thanks for your help but I will stay on the stock rom et deblaot it myself until there's a multi 'alleged' csc rom.
[Galaxy Tab S2 Android Development] Svan987:
For the Wifi-Direct flashable extract it. For AllshareFileShare, AllshareFileShareServer and AllshareMediaShare copy "lib" directory into respective system/app directories (don't need to check permissions at all) then reboot.

Will update the Flashable files to v3 when I got it fixed. (Files are updated)

Cheers.

[Galaxy Tab S2 Android Development] AesopRock127:
So first off I'd like to thank all those involved in this rom. Very cleaned up stock-like rom which is working great, no problems whatsoever. My only issue is I cannot get live wallpapers to work. Is this one of the things that was cleaned out of the stock rom?? Anyone else having this issue? Also is there any way to fix this? It's not a huge deal but I do miss my live wallpapers and am curious if this is able to be fixed
[Galaxy Tab S2 Android Development] jhill110:
Download "packages removed" archive for your device. Extract the files and with your file Explorer re-insert "system/priv-app/SecLiveWallpapersPicker". See if that helps the issue.

Hope this helps.
[Galaxy Tab S2 Android Development] AesopRock127:
Thanks a lot should have realized that. Is there any others i need to have live wallpapers work because I seem to recall there being several needed for live wallpaper or just the one? Thanks again

Never having used them I'm not sure. I see in settings /wallpaper there is a live wallpaper category.
