im on twrp 3.0.2-0

using the twrp file manager there are no files or folders in the /cache directory.
[Galaxy Tab 4 Android Development] x0acake:
Awesome, thanks! Working great for a few days now
[Galaxy Tab 4 Android Development] g_ding84:
That's because its not mounted.

Its time to go to Odin and reflash the full stock .tar.md5 and restore you tab.

/cache and /data should be automatically mounted when you boot into TWRP.

Hello,

i use the Tablet as Navigation but its really Quiet.Can we make it Louder??
[Galaxy Tab 4 Android Development] the_desaster:
i tryed to... but i got a problem in odin when flashing.

"setup connection" and thats all.

i found some solutions and start a new try later.

Thank you all for your work on this ROM. Finally able to get the stability and performance that should have come from the stock ROM or fixes by the manufacturer.

The download link doesn't seem to be working :(

I'll try again later. Damn you navbar!

What android version is it? Like 6.0 Marshmallow?
[Galaxy Tab 4 Android Development] XSWG:
Android 4.4.2
[Galaxy Tab 4 Android Development] Tech Master Race:
Then what's the point of installing that custom rom? Like it's literally downgrading it because my stock Samsung Galaxy Tab 4 7.0 (sm-t23nu) is 4.4.4 kit kat.
[Galaxy Tab 4 Android Development] Pirum:
Great ROM, my (young) kids had filled up the internal storage of their "gaming tablet" and I had to root and install link2sd and chose this ROM.

My current configuration is standard T230 with 8GB internal storage, and sd-card storage 2GB FAT32 & 14 GB ext3 storage for link2sd. (I had to tell link2sd the 2nd partition was ext4, but that's another story)

Only issue: I tried to remove all gapps using the script from early in the thread, as my kids won't need them, and install pico gapps from http://opengapps.org/ . I downloaded gapps for 4.4.x but on install in twrp it will said my API level was 17, as in Jelly Bean 4.2, and install failed.

Anyway, I guess I could find other gapps, but is it a problem with TWRP 2.8.1.0, the gapps package i downloaded, my tablet, or with Acheron? For now I keep Acheron with default install and it seems to work great.
[Galaxy Tab 4 Android Development] D M J:
DIY Post or YouTube?

Is there one post or YouTube video that walks you through all the steps? This thread is enormous.

I have a T230NU and want to use it w/ my drone but the Nook software is a huge PITA and really slowing it down.

Thanks
[Galaxy Tab 4 Android Development] g_ding84:
All you need to do is read the install ditections in the OP. That will walk you thru everything.

download ROM to device (internal or external)

VERIFY MD5 SUM BEFORE FLASHING!!!

reboot to recovery ( TWRP 2.8.7.0 )

advanced wipe - Wipe cache / dalvik cache / data and system

install ROM zip

(not needed but you can wipe cache and dalvik cache after install again)

reboot -

boot time will take around 4-5 mins - everything is being set up

set up accounts / preferences / normal set up

$$$profit$$$

Make sure you have a custom recovery first.

This will get you rooted with TWRP 2.8.0.1

Then in the second post update to newest TWRP. Its linked in the second post.
[Galaxy Tab 4 Android Development] D M J:
Haha, I feel old or lazy. I wish I knew someone closer by that could do this for me.

Where do I get the custom Recovery from? I just want a bare bones, non-Nook Tab that will run DJI Go 4 perfectly s:eek: Is that even possible?
[Galaxy Tab 4 Android Development] D M J:
Can't install the Samsung driver so I can't even start the process :eek: I've tried the Active X change and it didn't work.

I asked at work, couldn't find anyone that rooted their phone so I think I'm SOL. Thanks though.
[Galaxy Tab 4 Android Development] mohammad.nomaan:
Awesome work. Lovely ROM [MENTION=4644109]g_ding84[/MENTION]

Any news/plans on updating the base from 4.4.2 to 6.XX or 7.X (Android 7.0 Nougat would be awesome)

Thx anyway.
[Galaxy Tab 4 Android Development] g_ding84:
Still waiting on the official 5.0 / 5.1 update from Samsung.

This is based off the official firmware. (Aka, stock)

So if Samsung ever releases that update I will update accordingly. However, since it's still stuck on 4.4.2 this ROM will be stuck on 4.4.2

Not saying it can't be themed to look like 6.0 or 7.0/7.1
[Galaxy Tab 4 Android Development] mohammad.nomaan:
Thnx for the reply

I guess sammy won't be updating the rom anyway as the device is old for them.

If u can theme it to look/feel like MM or N it will be great

Hi [MENTION=4644109]g_ding84[/MENTION] !

I just have a general question about the tablet ROM:

Is it possible to build a custom ROM for SM-T230 based on Android 7.1 ? ( from LineageOS 14.1 for example )

Or are we stuck with firmware limitation, incompatible device tree, outdated drivers, lake of open sources from Samsung or whatever ?

I'm interested in finding a solution to build an up to date custom ROM from source despite I'm very new to this cause I find the stock ROM boring despite your great work on top of it.

In any case, thanks for your time and your valuable work on the SM-T230 stock ROM.
[Galaxy Tab 4 Android Development] g_ding84:
It is possible to build, however since this tab uses marvel chip set there are driver issues, like WiFi not working is one of the issues.

Samsung only open source is the kernel and that is KitKat 4.4.2 based.

You can try hitting up sub77 and CTXz as they have the device tree set up on GitHub.

Man im using this rom since the start on my tab4...works awesome, much better then stock...

Tab still works almost like first day...battery is still great...I had one month idle and 2h SOT since I dont use it much anymore, but still its pretty nice device with your rom.
[Galaxy Tab 4 Android Development] dogfyter:
Noob here. Everything works great. I could not get the allshare zip reinstalled with twrp. It says, "Unable to open zip file." Which is fine. Allshare may be necessary for me to "Connect and Share" with other devices. So if anyone knows what I'm doing wrong please tell me.

But what I would actually like to know is if there is a way to "Screen Share" not "content share" with files, etc.. I want to share what is on my actual screen with out playing any media, files, or content. My LG phone has miracast built in and it screen shares onto my Samsung Smart TV just fine. But I have never figured out how to do that with my tab 4. I appologize if I have drifted into something that belongs in a different forum.

Thanks again for the help
[Galaxy Tab 4 Android Development] mkhtfld76:
I also have been using this rom from the beginning. Thanks g_ding84 for sticking with us when no one else did.
[Galaxy Tab 4 Android Development] dogfyter:
update

The first copy of allshare downloaded as corrupt. So I redownloaded from the second Mirror and it worked just fine. I still think its funny that I can screen cast with two non samsung devices to my samsung tv but, not with my tab 4 no matter what apps I try. Stupid Samsung.

Again, the rom has been a great upgrade. Thank you.
[Galaxy Tab 4 Android Development] g_ding84:
I'm still around. Just more monitoring the thread lately. If and when I get some solid free time I'll look at actively picking this back up.

[Galaxy Tab 4 Android Development] MeniscusKing:
Can confirm. I was wracking my brain over this one for about an hour.
[Galaxy Tab 4 Android Development] Jollyriffic:
figured out all my issues, so deleted the original text.

after installing the os, remove the bar, and su.. what other things should i flash to get the best performance?
[Galaxy Tab 4 Android Development] Jollyriffic:
is there an actual fix to this

because even turning off all sync settings doesn't help.

or someone know of a good rom that isn't plagued by this issue?
[Galaxy Tab 4 Android Development] MeniscusKing:
Is anyone else having issues with Pokemon Go?

I set this tablet up for a friend with this rom so that he didn't have to deal with the Samsung bloat. I made sure to unroot it just before running Pokemon Go because I know you can't sign in otherwise, but for some reason whenever he goes to tap on a Pokemon or looks at his items the game crashes. Would anyone happen to know what's causing this?

Also I've read up that it may just be this model of tablet that's having issues, but I've only been able to confirm that from a select few sources.
[Galaxy Tab 4 Android Development] thisisapoorusernamechoice:
Use magisk. I have lineageos (rooted) on my galaxy s5 and Pokemon go still works, thanks to magisk.

It also makes Android Pay work with root
[Galaxy Tab 4 Android Development] MeniscusKing:
I would use Magisk but sadly it doesn't support Android 4.4.2 or 4.4.2 doesn't support it. ? Whichever way around it is. The Galaxy Tab 4 7.0 t230nu has a different chipset than all the other Galaxy Tabs so there aren't any later version Android Roms for it. Thanks for the reply though. ☺️
[Galaxy Tab 4 Android Development] Rachadell93:
I tried running Pokemon Go on my SM-T230 when it was new (so no root or roms or anything else) and had the same problem. The game would start up fine and I was able to use Pokestops but when I tried to catch a Pokemon it would just crash after tapping them. So I thinks its probably a device model problem.
[Galaxy Tab 4 Android Development] teamgs:
Greetings, Just installed this ROM mainly to bring life back to my kid's SM-T230NU's by clearing out garbage. Also looking for the ability to have apps automatically install on the SD card. I want to try ADB to do this, but I can't find how to enable USB Debugging. The hitting build version 7 times doesn't work. any ideas?

Regards,

[Galaxy Tab 4 Android Development] jimmy999x:
You must click on compilation number
[Galaxy Tab 4 Android Development] teamgs:
Thanks Jimmy, but I don't see a compilation number. In General, About device, there are only Status, Legal info, device name, model number, android version, kernel version, and Build number. Click like a madman on all of these does nothing. Except a small easter egg (at least for me) when I clicked a few times on the Android version.

Wonder what I am missing?

How to improve on perfection?

I see folks asking for battery improvements.

I use Acheron with Greenify, and use the tablet only occasionally. The combination of Greenify and Acheron gives me 2 days or more between charges! You can't ask for better than that!

Can you try clearing cache and data from the gallery in settings.

If it still persists please pull a catlog

How did you download the ROM?

Does the MD5 sum match?

What version of TWRP are you using?
[Galaxy Tab 4 Android Development] ClockUpEx:
Hey there! I tried to reflash because i thought it might fix the fc issue. Now i get the problem of every flash it reboots before even finishing and goes back to recovery :(

I used the twrp from the second post in the thread which the you told me. I noticed that the twrp cant verify md5sum! Kept saying cant find, but when I verified it using pc it says it's fine! Downloaded the ROM using IDM and everythin worked at first.

Everything worked at first but when I reflashed I now cant flash even other roms :( please help
[Galaxy Tab 4 Android Development] ClockUpEx:
Still have no idea what to do rn :(
[Galaxy Tab 4 Android Development] g_ding84:
That's not good.

The only thing is see if you can sideload another ROM Zip and try to recover that way.....

Also, when you are flashing the ROM, is system unmounted?

If you format system in TWRP it will keep /system mounted.

Wipe data, cache and system

Reboot recovery

Flash ROM

Reboot

See if that works.
[Galaxy Tab 4 Android Development] ClockUpEx:
Tried but it did not finish flashing. Instead it just goes back again to recovery :( tried rebooting to system after that happened but it's just stuck on the logo as of now :( .

I have a stock rom in the internal storage but same thing happens :(

---------- Post added at 10:12 PM ---------- Previous post was at 09:59 PM ----------

So I was thinking of reflashing an older version of TWRP but I don't remember where I downloaded. So I went to google and found a blog like site. Used odin to flash recovery while in download mode. Worked.

I immediately forced reboot since I have no OS and it will just get stuck to the bootlogo. Then I wiped data, system, cache, and dalvik. Flashed the Stock Rom and it's back up running :D Nice!

I'll try to flash the ROM with the TWRP it's version 2.8.7.0 as it says on top. Let's try ^_^ I'll edit this after

---------- Post added at 10:28 PM ---------- Previous post was at 10:12 PM ----------

Okay so it worked suprisingly for a beginner like me :highfive: yehey! Thanks for helping OP! Highly appreciated! I'll try the debloater and samsung apps remover :P ! Thanks again for this rom ^_^

Oh no the debloater causes gallery FC so i had to reflash and only use the samsung apps remover ^_^ it's all great now ^_^
[Galaxy Tab 4 Android Development] g_ding84:
[MENTION=8207422]ClockUpEx[/MENTION]

Thanks for the report. Glad you're tab is back up and running.

I'll have to make a note about debloater script causing that error.

FYI, I have done a bit of de-bloating in the ROM itself.

First, please do not quote to whole OP.

Second, I'm not understanding the request. Post what up top? And what topics are you referring about?

It's not criticism if I need to lay out the OP/second post or their post better. I don't think its bad. Maybe cleaning it up a bit....If that's what you are talking about.

I put the download links at the bottom of the OP to make people read. Lol

[Galaxy Tab 4 Android Development] Justray:
Greets!

After having problems installing apps because of "memory is full" BS (+2GB free space after a fresh install with the SAME APPS, the **** is using my space :confused:) , I decided it was time for a fresh start. Came checking for updates and lo and behold, nice updates still. After a clean wipe installation, everything seemed to work just fine.

Love the black background for recent apps and its back! Also, the issue that I couldn't rotate the screen inverted portrait was solved! All fine and dandy...until...

"If ain't broke, don't fix it." Should be our motto. Saw the new TWPR 3.0 and update it... bootloops. Funny cuz it worked then it didn't. I thought it was the ROM at first. Flashed the TWPR from the OP and the ROM again. All good :highfive: So far no contacts stopped working errors...yet.

:victory: g_ding84 Thanks for the time and effort!

---------- Post added at 02:07 PM ---------- Previous post was at 01:41 PM ----------

In the old ROM I found a workaround. Discord app allowed me to 360° then you just lock the rotation. The new update has 360° rotation with no issues. :good:
[Galaxy Tab 4 Android Development] maidenlissa:
So, uh... how long should this 4-5 mins actually take? At what point do I start worrying that something went wrong?

Sorry, but I don't deal with this very often, and it's only the 3rd time I've installed a custom ROM on anything. I'm very good at following directions, but I've been looking at this boot screen for at least 20 minutes. It's probably something stupid and simple.. I had already rooted my tablet yesterday, so I updated to the TRWP version 2.8.7.0 (had 2.8.0.1), wiped the things I was supposed to wipe, and installed the latest version of the Acheron ROM (V2.3.5 SM-T230NU). As far as I can tell, it worked. I wiped the cache again and then reboot. Now it seems to be stuck. I even tried searching various things to see if anyone else had this problem, but I didn't find anything.

What do I do next?

Device:: T230NU

Baseband: not sure.. I don't remember(sorry :eek:)

ROM Ver: Android 4.4.2

---------- Post added at 07:50 PM ---------- Previous post was at 07:19 PM ----------

GAH!!! Nevermind! I forced it to boot in TRWP and told it to install Acheron again, and this time I didnt wipe the cache after, just reboot.. and it worked. I knew it was something stupid! lol :silly:
[Galaxy Tab 4 Android Development] maidenlissa:
Ok... the newb girl is back! I've got everything installed just fine, but now I'm trying to partition my SD card to add extra storage to my system because I want to have more apps. I go into TWRP and tell it to partition SD, EXT size 5120, swap size 0, File System ext4. It fails and says it can't find the device I'm trying to partition. I even tried ext3, changing swap size, removed and replaced the SD card, and anything else I could think of. Is what I'm trying to do even possible with this ROM? I've seen people talking about partitions in this thread, but I wasn't sure if they meant on the SD card or what, and I didn't see anyone talking about TWRP not finding it. I can use the sd card just fine when I load the ROM. Can anyone offer me a little guidance here?

p.s. Thank you sooo much for creating this ROM! I love it so far. Pretty easy for me to figure out, but plenty of options once I learn what I'm doing lol.
[Galaxy Tab 4 Android Development] g_ding84:
First, I'm assuming your SD Card is formatted EXT4 or FAT32 for TWRP and you can install ROMs from the SD Card.

Is the SD Card mounted while you are trying to format it?

Second, please correct me but I thought TWRP only supported EXT4, FAT32 or F2FS partitions. What file format are you trying?
[Galaxy Tab 4 Android Development] maidenlissa:
The SD card is formatted FAT32. The SD card was mounted when I formatted... should I try reformatting it a different way? I just did it through the settings menu.

I was trying to make an EXT4 partition, because I read somewhere that it works best for... uh.. basically tricking my tablet into thinking it has more internal storage. I can't think of the right word for that lol.

Before and after installing any custom ROMs, I kept running into apps that wouldn't install because it said I didn't have enough space... even when I had over 3GB of internal memory free. So I've spent the last 3 days trying to make this tablet better.
[Galaxy Tab 4 Android Development] kssxs:
Hey, just wanted to say thanks for the ROM, running fairly well overall. Just one issue that I thought I'd pipe in on, and that is the 5G wireless network issue that has been brought up previously. I just flashed Acheron last night, and I've got the same issue. No 5G WiFi networks being detected to connect to.

I hope the dev is still working on fixing this!
