Me too and I have now three of the same tab. We use it to play minecraft in groups and this tab is fast, smooth and easy to handle and that for kids too. My son is 9 years old and he can root it, flash the right ROM and kernel. OK the right gapps is my work but this tab is used very often here in the Netherlands. We, a group of 32 people, father's with a son or daughter, playing a lot that mc stuff and everyone has 2 more tabs tm230.

So don't let it die because it is my job to hold these tabs up to date ;). My son and me we love it to handle that stuff.

BTW: my little daughter, see my avatar, is starting to asking what she can do to learn it. Oh god I think I got hacking childs. What will the future bring when this go on? ;)
[Galaxy Tab 4 Android Development] darksidesh007:
We got our twin sons the NU. Going to flash this within the next couple of days (when I get a chance to do it). Sounds like a great ROM.
[Galaxy Tab 4 Android Development] Tech 4 9:
Still loving the rom! Should USB OTG work? If so how? If not...fix? Thanks.
[Galaxy Tab 4 Android Development] g_ding84:
No it does not. No fix as I believe the hardware doesn't support it. (From what I have read) if there is a fix it would have to come from a custom kernel.
[Galaxy Tab 4 Android Development] Fyredragon:
maybe Samsung releasing Lollipop so the wizard g_ding could make it happen? :) Hey all sorry been so quiet here for awhile but been sick for awhile and really did not feel like doing much. I'll be around bothering more now and hopefully we can get a gift from damn Samsung before Christmas :)

Just popping in to say this ROM is tits. Went from potential buyer's remorse to "wow this is a nice tablet" in a matter of minutes. Solid work, mate.
[Galaxy Tab 4 Android Development] Fyredragon:
OK folks seems I have a problem that I cannot figure out and hoping for some ideas here. First off seems my tablet is running like it is in mud. I go to google play store and it is taking forever to load the pictures for the apps on the front page. Sometimes taking upwards of 5 mins or so to actually see the pictures. And if you scroll down the pictures at the upper half of page disappear again. Thus restarting the long restore of them. Rebooting tablet does not fix the problem either.

Secondly, it seems the apps are loading slower and slower also. I can click a game app to start it and what used to be seconds to get it up and running now is taking minutes and those that need a wifi connection for playing are taking a long time to connect or even forcing a restart of the wifi. I have well over 3 gigs of space available on tab and another 26 gigs open on SD card so doubt that is the problem.

Battery life has become horrible too over this. A normal full charge used to last for hours and now even a full charge is good for maybe 2 hours of actual usage. If not in use the battery is fine and shows no real discharge. I am praying is not the battery though as I live on a fixed income with really nothing to spare due to disability not allowing me to work. If anyone thinks is the battery causing this can you please let me know of a CHEAP place to replace battery?

I am really getting worried the tablet is dying and I may never see lollipop on it LOL. And if it is at it's end I will not be able to afford to replace it leaving me tabletless which would drive me insane as I rely on my tab for everything from games to paperwork for doctor visits and lists I need to have for doc too.

Any ideas? I am hoping for a miracle so I can keep my tablet going and also be able to stay in our little group and be able to whine and moan about updates LOL

Thanks in advance

What have you tried so far to fix the problem if it's software? Clean flash? Wipe dalvic and cache?
[Galaxy Tab 4 Android Development] Fyredragon:
Heya,

Have not clean flashed yet as was not sure it would be of any help. I kind of dread a clean flash at this time because of how slow this thing is moving with normal tasks and would hate for the issue to not allow a flash if it is being caused by something else am missing. Should I just try wiping dalvic and cache without a clean install?

Thanks for reply

Dragon
[Galaxy Tab 4 Android Development] pontif:
You never know until you have tried all avenues. What makes this fun ???. But deleting dalvic and cache starts apps over in the system but a complete wipe brings you to the beginning. I also would try a dirty flash with a wipe of dalvic. All could be beneficial or just be in the same boat.
[Galaxy Tab 4 Android Development] Fyredragon:
LOL yikes. Sounds like fun times ahead. This outta be fun on pain killers :) Thank you so much for your replies :)

Edit: WOW! Am a Senior member Finally!! Yea!!!
[Galaxy Tab 4 Android Development] pontif:
Lol welcome to the club. Official flashaholic. How tablet coming along?
[Galaxy Tab 4 Android Development] Fyredragon:
LOL thanks. As much as I was posting for awhile I thought I would be senior before my tablet decided to make me mentally senior and brain dead :)

So far wiped dalvic and cache, no help. Tried a dirty flash and it decided to fight me for what seemed forever before I finally got it to boot. Did not want me back in recovery for some reason. I think it doesn't like to play "dirty" (couldn't resist)

Since it took so long, will have to wait until tomorrow now to clean flash it as am wore out from the fight :) I hope that is what will fix it as it is getting so bad. Chews through battery hard when trying to load any graphics from games apps and the store. If it don't cooperate soon I may have to go beg on the streets for a tablet LOL

[Galaxy Tab 4 Android Development] Tech 4 9:
Try adding the stock kernel second in your flash. This rom wouldn't work for me at all until I tried that.
[Galaxy Tab 4 Android Development] Fyredragon:
Hey all

Sorry for not responding yesterday as real life loves to get in way when your busy. Am appreciative of all replies so far. I have tried all steps mentioned in other posts to no avail. A clean flash did not work.

So now questions to tech or anyone else.

In order to flash the stock kernel will I need to re flash the Rom?

Do I need to wipe dalvic and cache also?

Can I dirty flash the stock kernel if no need to re flash rom?

Something tells me also when I looked on first page of thread there is a possibility I used the stock t231 kernel not the NU. So as not sure of the difference could this have been the cause of my problems?

Thanks for all the help and am praying this may be the fix. So thank y'all for the responses. So appreciated to me who is feeling dumb these days

[Galaxy Tab 4 Android Development] :
f,

before anything else , make a full backup.

okay this is [MENTION=4644109]g_ding84[/MENTION] 's listing for available stock kernel images

https://www.androidfilehost.com/?w=files&flid=23711

and my listing of stock kernel images is here

https://www.androidfilehost.com/?w=files&flid=24295

after your backup first try a factory reset via recovery just to test if performance is restored, which it should be.

if not, restore your backup then flash the appropriate kernel image by the usual means, unless the specific image you need is not present.

Note- if your are rooted, pull all your apps out of /data/apps through adb, do this BEFORE factory resetting. you will be pulling

them to whatever working folder your terminal is in on your pc. Then do your factory reset.

adb pull /data/apps/

If your performance issue is corrected then push those apps back MINUS google apps present from gapps automatic update.

meaning play itself, google login services and the like, this includes hangouts and such, also webview.

go one directory up in terminal on pc

cd ../

then run

adb push apps/ /data/apps/

permissions should survive if you are working in a linux OS otherwise you will also need to correct permissions.

adb shell chmod -R 755 /data/apps/

adb shell chmod -R 644 /data/apps/./*.apk

that should do it for perms, although it might just be easir to push your backed up apps to sdcard and manually reinstall them.

some ideas.

Thanks for everything!

I have now a SM-T230NU and after reading a lot options, I want to install your ROM. I have a couple of questions:

1. I checked that it says IR blaster was removed, so is the IR of my SM-T230NU going to work?

2. If I am not wrong, I must root the device first. I can use any of these two methods, right?: this one or this one. I just have to change the TWRP for the version 2.8.7.0 you said, and the rooting will still work, right?

3. Following either of those two methods, the 6th step is about installing superSU. Instead of rebooting, will it work if I go directly to wipe everything and install your rom?

Thanks!
[Galaxy Tab 4 Android Development] g_ding84:
1st - IR blaster is already installed in the ROM. You just need to flash the *STOCK* SM-T230NU kernel to activate it.

2nd - you don't need root. You just need TWRP (the latest version )

3rd - wipe data, system, cache and dalvik cache - install ROM and reboot. (No need to install SuperSU as this ROM is running the latest version 2.52.
[Galaxy Tab 4 Android Development] thelous:
will this wersion of TWRP work on lastest OD2 firmware? (rooted already)
[Galaxy Tab 4 Android Development] g_ding84:
I recommend 2.7.8.0

But to answer your question, Yes.

EDIT: 2.8.7.0
[Galaxy Tab 4 Android Development] Latiosman:
So much easier than I expected. Tomorrow I will do it. thanks!
[Galaxy Tab 4 Android Development] thelous:
Thanks for answer, but in installion guide its recommended to use twrp 2.8.7.0, will 2.7.8 do the same job?

[Galaxy Tab 4 Android Development] Fyredragon:
Heya,

Am sorry has taken so long to reply to you and all your awesome help above. I am fighting pneumonia and with my disability it keeps forcing me back to hospital, thus my lack of reply for days.

So, this morning I finally got back to trying to save my tablet per your instructions. I'll be honest after doing a full back up and almost hitting factory reset before making sure I reread post at least three more times, I realized as am rooted that I needed to do ALL your steps. Well that is where am stuck. I am at a loss on how to utilize my adb to pull apps to pc. Every command I try I am getting an error stating device null not found.

I know I am missing something and trust me am out of my element here as my experience lies more in PC than Linux and commands. Am sorry, but still learning and am tech challenged on this part. Also am wondering as when I reset tablet and sign in my apps are restored from google account so am not sure if I need to actually save them? The few games I have should (hopefully) be saved in the cloud as to data to restore me to where I was. I am not confident with that storage though so was thinking best to try your way and am now lost. :)

I really need to do something fast as my battery usage is insane @ losing a good 30% an hour of light usage. Either I see if above helps or hope to find an insane cheap battery, or hope the little fat man in the red suit brings me one as I can't afford one LOL

Thanks again so much for your reply and apologize again for long delay in reply

Indeed bloat crap, speed increased little but responsiveness has increased quite a lot. Just amazing feeling the device work as its almost full potential. Just installed the OC kernel so lets rock this cheap ass tablet another whole year!

My eternal thanks to all the involved!
[Galaxy Tab 4 Android Development] :
f,

hey hey, okay even if your tab is running slow/crappy, you may be able to skip the adb step as long as you can get the tab running in normal operation and selinux is disabled/permissive by running in terminal

su

setenforce 0

mkdir /sdcard/apk-bak

cp /data/app/* /sdcard/apk-back/

and with luck as to the aforementioned conditions you can back up your apps that way as well.

The longer road in that vein is to make your full back-up as previouosly mentioned on an external-sdcard [if you're worried about your internal sd getting messed up, which it shouldn't] , AND then go ahead with flashing/re-flashing to the full stock experience or whatever , then pull a copy of

the back up you made to your pc and extract the data.tar.gz or the like and your apps would be there.

As for you OS preference,

Windows= install appropriate samsung usb drivers, i believe [MENTION=5954417]thisisapoorusernamechoice[/MENTION] aka TIAPUNC has those posted on his firmware release thread in general section. You will also need to install adb for windows ! you will need to research for the correct installation.

Linux= depends on your distro as to what repo contains android-tools-adb else you should not need anything else.

I know for debian/wheezy you needed to get AN UNREASONABLE AMOUNT OF WHAT SHOULD BE IN MAIN DEVELOPEMENT TOOLS/PRE-REQS WITHOUT HAVING TO HERE ABOUT YOUR PHILOSPHY TEAM DEBIAN! :eek: ! :eek: ! :eek: !

Okay last question before i flash this: im on sm-t230, i flash european twrp from this thread, now i see theres OD1 and OD2 kernels, i need od2 if i flash rom will it name my device SM-T230NU, set kernel OD1 and then i do first reboot and (i guess) i flash from twrp the OD2 kernel or....?
[Galaxy Tab 4 Android Development] Fyredragon:
Heya,

OK first off thank you so much for your replies. Highly appreciated. So far have factory reset and same problem occurs. it's very slow loading and icon pics taking forever to load. Restored my back up to it and was going to try to use your above steps to make sure I created right back up.

The second line is my problem on the terminal. "setenforce 0" says cannot be found. Yet I proceed with the parts after that line and the back up is made to sdcard as designed.

Am leery of just proceeding in case that line matters in the final stage I can try to save my tablet. Am I worrying nothing or should I just go ahead with the reset and new flash?

Again thanks moon And Merry Christmas :)

Dragon
[Galaxy Tab 4 Android Development] thisisapoorusernamechoice:
You should only use the OD1 kernel if you have an SM-T230NU, it will make the IR blaster work again. If, as I suspect, you have the SM-T230, use the OD2 kernel. Flash the OD2 kernel zip right after you install the rom, you shouldn't have to reboot in between the two

Oh okay! Thanks for answer, gonna test this after i back up few files... my stock rom is using 1.1GB ram even i dont have any apps open, better try if this rom will fix it because some apps i use wont work with 200 mb ram.... (e.g emulated linux)

Okay flashed succesfully! Looking great so far! Uses 600mb ram, way better than old stock which used 900mb-1GB ram! also chrome seems to be running smoothly! (On stock it was slow) the stock boot animation of this rom is huge stock animation, does not look good! Also xposed wont load modules to download section, i installed xposed framework succesfully and reboot...... also how does those additional mods work? Just flash and reboot or wipe something? Is AOKP_bootanimation.zip flashable via TWRP? Theres installion guide of bootanimations on that thread but i want AOKP one^^ it seems like you can get rid of clear recent button with gravity box [kk] just find the option and select off and it will be removed!

Hey all,

Ok weeks of trying everything under the sun and still the same problems. Slow loading things like the play store icons, web sites, etc. Battery life is really bad now over this. I literally can watch the dang thing discharge as soon as I do anything at all. Am wondering if possibly a bad battery can be the issue? If so where would be a hopefully cheap battery for this tablet? Money is a hassle as always, but if the battery is the cause, would it be worth the trouble for this tablet as god only knows if Samsung is even going to bother with this tab. Or do I have a soon to be paper weight and not worth the battery change? LOL

Would be sad if this tab is done with Samsung, but buying another tab would not be easy for me

Thanks for any ideas,

While this is appears to be the only active development, you might want to try the Barebones rom and the xposed modules recommended here.. I have been using it for awhile. The thread is closed, but a solid debloated version.. I had to go that route with the sync problems here with Google calendar
[Galaxy Tab 4 Android Development] g_ding84:
Have you tried running the stock kernel?

Under clocking?

Do you have Xposed installed?
[Galaxy Tab 4 Android Development] Fyredragon:
Heya Bud, LTNS

Stock kernel was in but there was no difference so went back to previously installed kernel that was installed. Xposed is installed. I under clocked back to 1066 from 1344 but am thinking I should under clock more? Am getting kind of leery as I feel am bordering on breaking my tablet or my mind :)

Let me know what you think. If nothing else I still lead back to battery with a very high discharge and still can't help but wonder if there is a correlation to this issue

Help before I pull my hair out(And trust me has been growing many years so would be a terrible loss LOL)

[Galaxy Tab 4 Android Development] dstarfire:
Any chance of implementing the pre-S5 button functionality (short-press/tap left-most button for menu, long-press home for recent apps/app switcher)? I can understand googles hatred of hardware buttons (and love of software-based controls), but I firmly disagree with it.

assigning menu simply involves editing a couple of text files and can even be done from the device itself. (details: xdaforums.com/showthread.php?t=2799050)

getting long-press home to pull up the 'recent apps' or app switcher is a bit trickier, but it has been done with another note 4 rom (xdaforums.com/tab-4/development/rom-android-5-0-lollipop-material-t3061873)

[Galaxy Tab 4 Android Development] Latiosman:
I dowloaded the "SM-T230NU_Stock_kernel_OD1.zip", is that one the Kernel to activate it?. Do I have to install it right after installing the ROM and before rebooting?? or when?

I was going to install TWRP 2.8.7.0 first. But I am not sure if I need the US or the European version. How can I check that on the device?

Thanks!
[Galaxy Tab 4 Android Development] g_ding84:
Yes that is the correct kernel zip

Where did you buy the tablet?
[Galaxy Tab 4 Android Development] doctazz:
stock browser

Curious...

Does anyone have the stock browser for KitKat available? I like Chrome, but I've always found the stock browser faster to use, especially when linking to social media sites. Even with the overclock kernel, at times the tablet's a bit slow to use. If I could ditch several social media apps, such as facebook and twitter, that would help speed up the tablet in general. A few other sites, like pinterest, work well for me through a browser. Doing this would free system RAM, additional CPU overhead, and reduce excessive wakelocks. Facebook is the worst offender. I have tried Greenify on my tab 4, but it slows things down too much, so I've taken it off.

There is a great alternative for fb and twitter in Google Play. It's called Metal for facebook (love that title! :)). It's essentially a web wrapper based on Tinfoil for facebook. Its author properly credits the Tinfoil dev, so I can trust it. Metal has notification support for fb, twitter, and fb messenger, so the fb messenger app can be ditched, if you don't care for voice calls or video chat.

Here's an article that details some recent issues about the facebook app, for Android and iOS. Also includes a link to a recent Reddit post: http://www.forbes.com/sites/gordonk...ok-ios-android-serious-problems/#5ad7b0b236a6

Total newbie here be gentle.

I have but two question about this rom.

Does this rom allow overclocking?

Does it improve the over all experience on the device (ie faster loading smoother movement from screen to screen)

If not then can you point me to a rom that does that? With a good download link.

Again im a newbie at Roms but i have been wanting to get into them its just thst there are so many different ones with different features and apps. Im sorry if this clearly does do what im asking but i read it all and couldnt find the info.

Also the reason why i am inatalling this rom is because i have a friend that told me my wifi problem ( connects and disconnects randomly after 5 or 6 mins of being connected my phone does the same thing and its also a samsung device.) Is he right?

Thank you guys in advance for any info you can provide.

You need to extract the .IMG file in the .rar to use it.

You can't use ODIN for that. You can use flashify to flash the TWRP IMG.
