They never light up. There isn't any backlighting for the soft keys. Mine never did from day one of owning the tablet.
[Galaxy Tab 4 Android Development] g_ding84:
Short answer, No.

Long answer, there is 1 test CM11 ROM. But WiFi, Bluetooth and sound doesn't work. (We are missing some Marvel chipset drivers) and it was made from the SM-T230 source. For the T231 we would need additional drivers for the modem for 3G.

That's why I gave the short answer above as No.

anyone know why my Bluetooth headset does not work with the application viper4android
[Galaxy Tab 4 Android Development] g_ding84:
Dumb question, (but it happened to me)

Did you turn Viper on for Bluetooth?

It has 4 adjustment screens. Headphones/headset, external speaker, Bluetooth & dock.
[Galaxy Tab 4 Android Development] g_ding84:

[Galaxy Tab 4 Android Development] jose_26_df:
if the screen is activated the Bluetooth I have about jbl headphones connected to BT E40
[Galaxy Tab 4 Android Development] g_ding84:
Doesn't look like you have the rest of the settings activated.

You have it on for Bluetooth but none of the other boxes (playback gain control and others) are not checked.
[Galaxy Tab 4 Android Development] jose_26_df:
If you activated and remains the same

As i got no response on other rom thread, maybe you're willing to help me:

Thanks for the answer!

[Galaxy Tab 4 Android Development] krakenthor:
Use an app like link2sd or rom toolbox only if you are rooted. And there is a patch in the form of an app called sdcard fix on google play that fixes the read/write issue. You have to use the sd fix before you can gain access to your sd card like normal
[Galaxy Tab 4 Android Development] g_ding84:
Folder mount from the play store will work. It patches the SD card issue. There is also apps2sd in the play store that will move them. If you have any issues let me know. I can make a flashable zip to patch the system so you don't need the other apps.

This ROM already has the patch for R/W access to the SD Card.
[Galaxy Tab 4 Android Development] g_ding84:
I made this zip for the SM-T230 and SM-T230NU STOCK(not on a custom ROM)

. This flashable zip will patch the SD Card R/W issues.

VERSION 2 - TRUE FIX

Also attached is FolderMount - install like a normal app - open - grant Superuser access - move apps and data to SD Card.

Working on New Version 1.4 - Side note - uploaded a mirror link to Mega

here : https://mega.co.nz/#!ulwwQJzQ!_TwQByaok_ob0KJfkDEaC5uKZQNRsohQaRGu9S97yd4

located in the OP under New Version download link
[Galaxy Tab 4 Android Development] the_dealer:
The new mirror link doesn't work, unless I'm doing something wrong. I've flashed v1.3 yesterday going from Safariking's v1.6, and I'm definitely impressed. This is the first time I've used Nova instead of touch wiz, and I love it. You did a good job on this rom, and managed to keep it lite weight and kept the memory usage down. Can't wait to try v1.4! Are there any mods to improve WiFi reception? No matter whether I was on factory, stockrom, or Acheron, my WiFi signal has always been week. My Sm-g870a will have full signal, where as my Tab will only have 1 bar.

Sent from my Samsung Galaxy Tab®4 on 38's
[Galaxy Tab 4 Android Development] g_ding84:
I wish there was something to do about the weak signal.

The mirror should work. Do you have the mega app installed on your tablet?

Thank you for the kind words.
[Galaxy Tab 4 Android Development] g_ding84:
Then unfortunately you would need to go to the viper4android main thread for support. All I did was add the app and make SE Linux permissive.
[Galaxy Tab 4 Android Development] jose_26_df:
I can not install:(
[Galaxy Tab 4 Android Development] g_ding84:
It's already permissive via init.d script. There isn't a file called setenforce in system/xbin for that app to use.

I can update the ROM to have gatenforce (check SE Linux status) and setenforce (to manually make it permissive)

Gatenforce goes in system/bin

Setenforce goes in system/xbin

Permissions for both are 0755

:D
[Galaxy Tab 4 Android Development] jose_26_df:
the strange thing is that nothing else is Bluetooth where I have that flaw in the other tabs if it serves
[Galaxy Tab 4 Android Development] dstarfire:
Please add option for old-style hardware button mappings.

I mentioned this earlier, but looks like it got lost in the noise.

Is there any chance of adding an option to use the hardware button mappings before (menu = app menu, not recent apps; long-press home = recent apps, etc.)? I know there's an xposed module for this, but it doesn't play well with some apps and seems to slow down the system overall (according to earlier posts).

Here's a link explaining how to do remap the back and menu buttons: xdaforums.com/showthread.php?t=2799050

. Doing long-press is a bit harder, but shouldn't be too hard for somebody who actually knows that they're doing (i.e. more knowledgable than me)

[Galaxy Tab 4 Android Development] lujki1:
Hi! This is a bit OT but I need help. I accidentally deleted Google App from Link2SD. Then I downloaded it from APKMirror, and made it a system app again in Link2SD. It was in priv-app but under com.Android.quicksearchbox something... I renamed it to Velvet.apk Is it now OK or something else I should do? Asked it here because I have this ROM. Sorry again.
[Galaxy Tab 4 Android Development] pontif:
Did you change the permissions?

You could also dirty flash the ROM again
[Galaxy Tab 4 Android Development] lujki1:
Yes. Permissions are all set. The problem was I was trying to replace Google App to an older version so I could enable Google Now in my country but I deleted it. Now it's enabled and I just wanted to be sure that I did everything OK when adding the app again.
[Galaxy Tab 4 Android Development] james28909:
Howdy folks ;) this will be my first time flashing a custom rom. I have read this whole thread xD and I have a question specifically about the ir blaster of my smt230nu and kernels. Will I be able to use ctx overclocking kernel and still retain ir functionality? Or will I have to use stock kernel? I also seen a ir fix and files, would I be able to use OC kernels and then use ir fix to restore ir function on OC kernel? I have 7 TV and 3 surround systems that all have dead/lost remotes.
[Galaxy Tab 4 Android Development] g_ding84:
For IR blasted - stock kernel

OC you can use the two other kernels.
[Galaxy Tab 4 Android Development] james28909:
so there is no way at all to be oc and use ir blaster??? thanks for such a fast reply btw :)
[Galaxy Tab 4 Android Development] g_ding84:
Not that I know of. Maybe.....depends on what's modified in the kernel and what source it was complied from. (ie T230 and not T230NU)
[Galaxy Tab 4 Android Development] james28909:
could i politely drop a request to the person whom is compiling that OC kernel (ctxz) and ask if he can compile a kernel that would work for t230nu? is that allowed? does xda forum support the mention system?

EDIT: sir [MENTION=6584695]CTXz[/MENTION] i realize this is not the thread for your OC kernel but does your OC'ed kernel support the ir blaster as well? and if not could you add support for it? i would greatly appreciate it. i have many tvs without remotes and would love to flash this rom with OC kernel and still have a working ir blaster :)
[Galaxy Tab 4 Android Development] CTXz:
Hey, unfortunately i do not own the tab and so I can't work on the kernel anymore
[Galaxy Tab 4 Android Development] james28909:
Ah ok, well maybe someone can chime in with a fix :o

Thanks anyways man.

Also i dont mind testing and if you want to collaberate lol.

Flashed rom with stock kernel, everything went smooth as butter. Thanks
[Galaxy Tab 4 Android Development] 4josh2u:
memory

i wanted to know how much memory is available after installing this rom
[Galaxy Tab 4 Android Development] g_ding84:
Depends on what you mean by memory.

The system block of memory is smaller.

The data block less is used - a bit more free (/data and internal storage)

There is more available RAM because the system is smaller.

Memory is hard to gauge based on your question. The flash memory on this tablet is broken up into different partitions.
[Galaxy Tab 4 Android Development] thelous:
This rom will use less battery and is stable as long as you dont remove gmail accounts etc.
[Galaxy Tab 4 Android Development] 4josh2u:
What does the mod remove clear recent apps do and can I overclock with this rom?
[Galaxy Tab 4 Android Development] g_ding84:
Remove clear recents mod does just that. In this ROM when you pull up recent apps the background is clear/transparent. The mod makes it black (like stock)

Overclocking is controlled by the kernel. The kernel included does offer overclocking.
[Galaxy Tab 4 Android Development] 4josh2u:
What app would I use to overclock?
[Galaxy Tab 4 Android Development] g_ding84:
I like Kernel Toolkit

https://play.google.com/store/apps/details?id=com.dsmartapps.root.kerneltweaker
[Galaxy Tab 4 Android Development] JayDream:
Or kernel adiutor
[Galaxy Tab 4 Android Development] g_ding84:
Just a quick heads up. Working on an update. It will be updated to APA1 base.

Also working on a firmware only Odin .tar to update to APA1.

[Galaxy Tab 4 Android Development] 4josh2u:
I installed the ROM I think it came out pretty good
[Galaxy Tab 4 Android Development] 4josh2u:
Been meaning to ask can I overclock straight after flash or do I need to find another kernel?
[Galaxy Tab 4 Android Development] g_ding84:
The kernel included is Nuki-Stock.

If you want to overclock I would use [MENTION=6584695]CTXz[/MENTION] kernel here : http://xdaforums.com/showthread.php?t=3101944

so as always a master piece of software.

Jesus i did not expected a new version for our lovely tab.

Two weeks ago i had made a clean install on all four tabs to get them clean

because all that crap what the kids had installed on MY hardware ;).

And now that and i have to do it again but now issue at all. I am lucky

to do things like that because i have no free time at the moment, ha, ha.

No really hold up the good work for us users and a big, big Thank You

[Galaxy Tab 4 Android Development] Mylt1:
stupid question time. how can i remove the included nova launcher from the rom before install? i have the paid version apk but cant install it because i have to remove the previous version before install. i tried using titanium to freeze then uninstall and still a no go.
[Galaxy Tab 4 Android Development] Tech 4 9:
]

So do I but didn't have to remove old. Might try clearing data/cache of the playstore app and let it restart. Then I think playstore services might have to update too. Once ps gets settled it'll prolly recognize your license for prime.
[Galaxy Tab 4 Android Development] Mylt1:
nope, still no joy. thanks for the idea though.
[Galaxy Tab 4 Android Development] Tech 4 9:
Try side loading both reg Nova apk and prime from a SD card perhaps?...skipping ps initially. Use apk extractor on phone to get apks on SD card...put SD card into tab...install(update since ones already on there) and then pull up playstore to check license?
[Galaxy Tab 4 Android Development] Mylt1:
side loading is how im trying to install it.
[Galaxy Tab 4 Android Development] g_ding84:
In /system/priv-app

Delete com.teslacoilws.launcher

Then go to data/data/ and delete the folder

com.teslacoilws.launcher

Reboot to recovery and wipe cache and dalvik cache

That will fully remove Nova Launcher. I'm not sure why you are having problems with the paid version. I have no issues with getting the paid version installed.
[Galaxy Tab 4 Android Development] mike2nl:
[MENTION=4644109]g_ding84[/MENTION]:

- It runs like a rocket

- Smooth as butter like 8 hours out of the freezer

- Stable as a rock

- BT, WiFi working and no issues at all

- Minecraft PE v 15.x is running faster and more stable seen by WiFi

- Overall, very well done and a big, big Thank You ... again;)

... and with the Kernel from CTX :D.

[Galaxy Tab 4 Android Development] Mylt1:
CM kept denying to delete the .apk in /system/priv-app. used root explorer and it did it first go around. got it up and running now and running nice and smooth. going to be setting this up as a tablet in my truck for streaming. now to just find a clock with weather that is larger than stock so i can see it while in landscape mode. seems like every clock is tiny when rotated.

[Galaxy Tab 4 Android Development] Denis:):
Thank you for this cool deodexed ROM ;)

I have been using it since the first version and it has been great. Only flaw I found is when I tried removing google account from settings or uninstalling from settings I would get proccess.android.acore has stopped working. And reset wouldnt help...

I needed clean device for some app recently so I did complete wipe with twrp and flashed stock firmware via odin, but it would constantly reset and stuck at samsung logo. Solution is to do factory reset/wipe and delete cache and reset. In case someone will need, It took me whole day to figure it out :rolleyes:
[Galaxy Tab 4 Android Development] ferry013:
Can i flash this on t231?

[MENTION=4644109]g_ding84[/MENTION] Getting any where with the 5ghz wifi issue? First boot thats the first thing i noticed, and 5ghz is important to me because it runs so much faster then my 2.4.

But we will see if i have any other problems, it honestly cant be any slower then stock was... It was killing me slowly. and painfully....
[Galaxy Tab 4 Android Development] sushiman79:
Hi all,

I think i'm getting stuck on the first part ... flashing the twrp image

Current info: SM-T230NU, 4.4.2, Patch Level 2016/01/01 (stock Samsung "up to date")

I reboot into download mode

open odin 3.10.7 (tried 3.09 also)

click AP

Tried a file "openrecovery-twrp-2.8.0.1-degas.tar"

(also tried TWRP_degas_usa_r1100.tar.md5)

(I created this md5 using a .img to .tar tool suggested elsewhere in this thread)

I get a successful flash from Odin

It reboots while I'm holding the right keys (vUP, pwr, home), I see a TWRP logo flash for just a moment ... and then it reboots and goes into the normal Samsung bootloader.

Any thoughts on what I'm missing? I was doing this with about 40% battery, although on other devices that's never been an issue.

thanks in advance!
[Galaxy Tab 4 Android Development] tbkrazeey:
Release power after you see the first samsung logo and keep holding volume and home. Holding power for too long forces it to reboot, but sometimes it's a bit moody getting into recovery with this tablet. (for me Anyway.)
[Galaxy Tab 4 Android Development] g_ding84:
I have been trying to figure that out since day one. Im not missing any files (I can always triple check) the files i do have are completely stock(nothing modified)

I'm wondering if its a mod i added that's breaking it. I'll have to review the mods.
[Galaxy Tab 4 Android Development] tbkrazeey:
2.4 is better then nothing anyways.

I have two issues, if they are just me I'm not surprised...

1- 3minit battery works on first boot but not anytime after.

2- Remove clear recent apps doesn't change it back. (impossible to read names on backgrounds etc) I tried it 4 times, clearing caches 3 out of the 4.

Other wise its quite a bit better then original rom so far.

Edit: dirty reflashed the rom and started getting android.process.acore has stopped.
[Galaxy Tab 4 Android Development] g_ding84:
What recovery are you using?

2.8.7.0 or 3.0.0.0?

Either one will work without issues. I noticed that the google acore issue is happening on dirty flash. I have yet to see the issue on a clean flash. What do you have syncing in the background?

3minit may have to be updated again.

I'll continue looking into 5ghz WiFi band issue as well. As soon as I have some free time. [emoji2]
[Galaxy Tab 4 Android Development] tbkrazeey:
2.8.7.0, since that's the one that was listed to use with the rom.

I did around acore by clean flashing the rom over again, I almost never have anything syncing, I keep it off that way I don't have any battery draining and extra notifications.

Do you think TWRP 3.0.0.0 might be better to use? I could try it and see if I have any better flashing luck.
[Galaxy Tab 4 Android Development] ferry013:
tested, working but can you make it to have also phone funcionality?
[Galaxy Tab 4 Android Development] blurv89:
Can anyone verify if the IR blaster works on this rom?
[Galaxy Tab 4 Android Development] tbkrazeey:
Yes it does. It's stock rom just cleaned out so everything works like it was meant to.

2.1 and 2.3

Description:

Can't install Neko RPGXP 1.6. I have almost 70 apps installed, all with no problems. This one doesn't wants to install, gets cancelled after a long while then a pop up comes with the message: App can't install error code-18. Google comes with very little info and the few "solutions" like cleaning Google play and services app cache, signing again with your Google account doesn't work.

Tested with your 2.1 Rom and refused, I decided to do a factory reset to discard the "I ****ed up something" but to no avail. Then came here to XDA for answers. Nothing worked. Found out about the 2.3 version and installed it fresh, absolute wipe (even sd card and system formatted).

Old version of the app Neko RPGXP 1.27 beta installs with no issues.

I'm attaching a log cat. Let me know if you need me to provide with any extra info. Thanks a lot for your time :o
