OD2 kernel is for the SM-T230, OD1 kernel is for the SM-T230NU. Overall they ought to be cross-compatible, but if you have the SM-T230NU and want to retain IR blaster functionality, you need the OD1 kernel, since that's the only significant difference between the two models
[Galaxy Tab 4 Android Development] Erock2k4:
Thank you!! I'll stick with OD1 I wasnt sure if there were additional features for each but it sounds pretty cut and dry.
[Galaxy Tab 4 Android Development] afelotreyu:
Hey Guys,

Subbing to this and planning an upgrade of the Tab once I complete my reading.

Thank you all in advanced.
[Galaxy Tab 4 Android Development] afelotreyu:
So!

used TWRP to install version 2.8.7.0 from your files.

Backed up my original rom

Wipe everything

Then installed 2.1.1

last removed the navbar.

Great work and much appreciated, it all works as expected!
[Galaxy Tab 4 Android Development] stevejohnson42:
I tried to install 2.1.1 with twrp 2.8.7.0 and kept stuck on initial boot , was successful using twrp 2.8.0.1 and version 1.7 with no issues. Rock solid, when I have more time will try again..

Thanks to developer and community

GravityBox

Has anyone tried GravityBox with this ROM ? Wanam Xposed seems the safer one to use with what is still a Samsung ROM - but it is missing a few tweaks that I used to use in GravityBox.
[Galaxy Tab 4 Android Development] BRoy_98:
Gravity Box is safe.
[Galaxy Tab 4 Android Development] afelotreyu:
So suddenly I started getting "android.process.acore"

Found a work around which is to erase contacts and contact storage data. Hopefully a fix can be implement on the actual issue next release?
[Galaxy Tab 4 Android Development] Fyredragon:
That one is a real irritating one for sure. Seems to be highly elusive too. Only fix I have found is the one you described. I found that on the web a ways back and once done the error for the most part stays gone.

Hopefully once lollipop rolls out and it can be implemented by Dev maybe it will be an end to it.

Dragon
[Galaxy Tab 4 Android Development] stevejohnson42:
I found it to be safe - just all the options don't seem to "play well" with the modifications Samsung made -- there are more options with the date format than with Wanam - but they don't seem to apply well. Big thing was that gravity box "tap to sleep" option does work. Will keep cautiously checking -- thanks again for your input
[Galaxy Tab 4 Android Development] BRoy_98:
yeah.. because old highly modifications of TouchWiz, it doesn't support all external modifications.
[Galaxy Tab 4 Android Development] Gregpl:
Could someone PLEASE PLEASE put up a link to the

For those with possible boot issues.

Here is the

SM-T230NU (ONLY!!!)

Firmware update ODIN .tar file. this will update your modem and bootloader to OD1 - this has only been tested on the SM-T230NU. I will be making another package just for the SM-T230

flash this in download mode with ODIN. if you don't know how to use ODIN there are a lot of places to learn......like google. :D :)

[Galaxy Tab 4 Android Development] g_ding84:
I should have the SM-T230 and possibly the SM-T231 firmware only files uploaded tonight or tomorrow.

I think some of the boot issues are due to a boot loader/firmware mismatch to the system and kernel. Hopefully these .tar files can correct that issue.
[Galaxy Tab 4 Android Development] Fyredragon:
Thank you much g_ding. Nice to see a dev who keeps working to make a product better all the time.

Only thing that still surprises me with you is that you have not built your own lollipop by now LOL :) Keep up the great work for us my friend. Is most appreciated :)

I'm working on syncing the CM12.1 repos and the degaswifi sources. Long story short going from Ubuntu 14.04.03 to 15.10 I needed to do a clean install. So I'm rebuilding sources. I need to get with [MENTION=3132221]sub77[/MENTION] and [MENTION=6584695]CTXz[/MENTION] for some CM12.1 (5.1.1) love.
[Galaxy Tab 4 Android Development] CTXz:
Sure, however we haven't been working too much on cm. If you could find out how to get WiFi working in cm11 we could move on to cm12
[Galaxy Tab 4 Android Development] g_ding84:
I'll hit you up on PM.
[Galaxy Tab 4 Android Development] Fyredragon:
that would awesome. Would be great to see CM 12 in some forms working. I know CTXz and Sub77 have done a lot on this and with all of ya I bet it would be a great change from the endless KitKat that Samsung does not want to upgrade to 5.1.1 on our tabs.

I see CTXz has replied as I was posting this and see the WiFi issue. Come on g_ding! You can fix it for em!! :)

hehe

[Galaxy Tab 4 Android Development] Spackenklatsche:
Very nice and fast rom, I love it.

Only problem I have is the android.process.acore bug. Unable to use my office account, one note and all this mail and contact stuff. One note is the most used app for me, is there a way to fix that bug?
[Galaxy Tab 4 Android Development] mike2nl:
You have done a complete new installation? Sometimes it helps. I do it by every new ROM update. Needs more time but it is better then all the other ways
[Galaxy Tab 4 Android Development] Fyredragon:
Have you tried the steps I outlined in a post way back? Clearing contacts cache and data in all apps in settings seems to fix it for me. Even though am clearing the afore mentioned I still have all my info after and the error is gone

Dragon
[Galaxy Tab 4 Android Development] Spackenklatsche:
I deactivated the sync process for Google fit, Sound search and so on, i made a full wipe, reinstalled all apps, flashed again, with full wipe before and after, nothing changed. With Exchange sync i got a new problem with the data exchange Service, it stopped running and did not sync my calendars with Google calendar.
[Galaxy Tab 4 Android Development] mike2nl:
Sounds like a bad flash so as by all the users with the same problem. A friend of mine has flashed the ROM two times with cleaning data, system, cache and dalvik. Then two times flash of gapps after a first ROM reboot and all is working now

Have you used old backed up data? That is an issue too, they can be damaged in any way.

Do a clean start with nothing of the old system and use play store to restore your own apps. That can have that typical bit-fallen syndrome ;).
[Galaxy Tab 4 Android Development] stevejohnson42:
the one bug --

Am I understanding the second post correctly ?

" you will get FC com.google.android.process.acore - this is caused by a Sync issue with Google and SecContacts - Fix, Go to settings>account>google>sync settings (only allow app data, pictures, sound search and gmail to sync - turn the rest off) "

If I do this my contacts and calendar do not sync then ? it is great that a work around is identified - but that really puts a crimp in my ability to use the ROM as a daily driver - which is unfortunate

Posting this on the hope that my interpretation is totally wrong --

Inputs greatly appreciated -
[Galaxy Tab 4 Android Development] g_ding84:
You will be able to sync your contacts. As far as the Google calendar, that I don't know because I don't use it. (Someone else that uses please chime in)

What I could try is removing Google calendar from the ROM and have you guys/gals that use it, download it from the play store and see if that fixes the issue.

Long story short, when I brought in Google Calendar I don't think it has all the needed files causing the sync issues.
[Galaxy Tab 4 Android Development] stevejohnson42:
I have Sync App Data and Sync Google Flt data checked - everything else is off ; I then installed digi cal and used it to Sync to google calendar - same error message and made the thing unusable ;

I did start with a clean install , twrp 2.8.7.0 and was installing 1.7 ; will try the latest one again --- but that is for another day

thanks for the efforts - really frustrating after having a Tab 2 7.0 and having all kinds of custom ROMs available to play with
[Galaxy Tab 4 Android Development] Spackenklatsche:
Let me explain what I did:

Downloaded twrp, Rom and navbar away patch

Flashed twrp

Flashed rom

Wiped

Flashed navbar away

Wiped

Rebooting and starting

Input of Google account settings

Updating apps via Google play

Begin of getting FC process.acore (sometimes, nearly all 5-10 minutes)

Installing apps via Google play

Adding Microsoft exchange accounts

-> getting FC process.acore instant

-> clearing contacts memory FC process.acore stops

-> Google calendar sync with ms exchange forces to close data exchange service every time I press the sync button in calendar, so no calendar is shown

Contacts are shown in the contacts app

Installed ms one note brings up fc process.acore instant and one note crashes after setting up account, no chance to use that app.

I love this rom, went back to stock but I hope to get it back, so smooth, excellent, eye candy !!!
[Galaxy Tab 4 Android Development] nomad7801:
Is there a way to install the ir blaster? That's about the only thing I am missing out of this rom. Is it possible to install it through TWRP? Never mind I found the files that I needed. Thanks.
[Galaxy Tab 4 Android Development] doughy2002:
Please advise what files you have as id love ir blastervto work

Regards
[Galaxy Tab 4 Android Development] g_ding84:
You need to install the stock SM-T230NU kernel.

[Galaxy Tab 4 Android Development] Elements1984:
Hello Acheron,

Thank you for bringing us this great rom, I tried many but yours is the most stable and fast in my opinion, that's why it has been running since 2 or 3 months on my tab 4.

I would like to report a bug and would like to know if anyone has experienced the same phenomenon.

So my bug is with the touchscreen, I touch it but it doesn't give any feedback, I usually have to touch it 3 times before it reacts, for example when I am watching a video on youtube or on vlc/mx player or even when reading Web pages on chrome. But once the screen reacted, the touchscreen works without a problem as long as I keep using it and I don't stay few seconds without touching it.

I don't know if it has something to do with the kernel that tells the touch to sleep after a few seconds of inactivity. I am using your rom with the kernel fro the rom, I didn't try installing other kernels though.

I tried erasing everything on the tablet from twrp, even the system partition, then reinstalled your rom, the bug still persists.

Any idea on how to fix that?

Thank you in advance for any input.
[Galaxy Tab 4 Android Development] g_ding84:
I have not seen reports or experienced this on this build.

The touch sensitivity and touch drivers are controlled by the kernel. I would recommend flashing the stock kernel or a different kernel to see if it persists.
[Galaxy Tab 4 Android Development] nomad7801:
My files

These are the files I got from another rom and I used TWRP to install the IR_blaster-fix.zip

the IR_files get unzipped and put into specific folders but I do not remember right off hand

which folders I put them in.

edit: put the android.hardware file in: system/etc/permissions/

put the consumerir.mrvl.so in: system/lib/hw

I just copied and pasted them into their folder using es file exoplorer and also do not forget to install the IR_blaster-fix.zip through TWRP

http://www.mediafire.com/download/jvqzqgreu6zbdyj/IR_blaster-fix.zip

[Galaxy Tab 4 Android Development] Elements1984:
Thank you very much for the great advice, I flashed Nukki v1.1 Linaro and the problem got fixed.

I didn't try other kernels though, so they may also be good to fix the touchscreen issue.

Right now I'm just waiting for the CTZ team to release the CM lollipop rom for the sm-t230 but it is taking far too long :(

Thank you again and have a great weekend :)
[Galaxy Tab 4 Android Development] nicolos35:
Language

Sorry for the stupid question .. but is this ROM takes in charge multilingual ? And more particular the french language.. I'm supposed yes because it's based on Samsung ROM but just to confirm .. Thanks a lot
[Galaxy Tab 4 Android Development] Elements1984:
Yes, this rom has all the languages that are on the original Samsung rom. And yes, it has french, I tried it myself ;) Don't forget to hit the thank you button if my answer was helpful :)

Oui, la rom contient toutes les langues contenues dans la rom originale de Samsung. Et oui, la langue française est dedans, je l'ai personnellement testé ;) N'oublie pas de presser le bouton "thanks" si ma réponse t'a aidé :)
[Galaxy Tab 4 Android Development] bingobill:
Did you make the zip to fix the transparent recent list ?

The only settings.apk I found in other roms was SecSettings.apk which I tried but made no difference.

This is the only issue I have with this other wise great smooth rom so I add my thanks too.

Would appreciate it if you could point me to fix for this issue.
[Galaxy Tab 4 Android Development] g_ding84:
I can get one up this weekend for ya.

I forgot its in the framework-res.apk as well.
[Galaxy Tab 4 Android Development] bingobill:
That would be appreciated, thanks very much :)
[Galaxy Tab 4 Android Development] Ghostrider:
if you get this Error Go to settings>account>google>sync settings and wait some time without pressing OK on the Box, some times you need to try 2 - 3 times,

but then it sync's. Than you can press OK on the Box. After this you don't get this Error again.
[Galaxy Tab 4 Android Development] Tech 4 9:
Can it ALL be left off?
[Galaxy Tab 4 Android Development] Ghostrider:
if you don't use any of them, then yes, but you need the Google Account for the Playstore.
[Galaxy Tab 4 Android Development] Tech 4 9:
Well...so far..fail. Did the wipe in twrp and flashed. After install and reboot it immediately goes to black galaxy tab4 splash screen forever. Any input appreciated.
[Galaxy Tab 4 Android Development] g_ding84:
Bad download?

Which TWRP version? 2.8.0.1 or 2.8.7.0

Staying on the splash screen is the kernel isn't loading. (Since the kernel indeed does work....as I'm running it) I'm assuming the download is corrupted. Also, try flashing the zip from internal storage. (Might be a bad SD Card....I've had that happen too)
[Galaxy Tab 4 Android Development] Tech 4 9:
Twrp 2.8.0.1 degas.tar and I don't even have a SD card installed. It was quite weird...i did finally get a Samsung splash..with the color..but it looked as if screen was cracked or broken...as if it couldn't render properly. I'm getting it back to od1 with Odin but I've tried twice now. Last was after fresh od1 install. Thanks for response. I will say this...when I downloaded this rom my connection was s u p e r s l o w...at best 500kb/s...took at least 30min but it did say download successful. Think that matters?
[Galaxy Tab 4 Android Development] Tech 4 9:
Another attempt after fresh download yields same results. Screen looks like a fritzed out/broken lcd TV screen.
[Galaxy Tab 4 Android Development] Afrobaron:
So I am finally getting back to trying this ROM out. When I last loaded a while back the wifi was slow and only 2.4 GHz band.

I just loaded this on one Tab4 7 that my daughter uses and wow. I am so happy to be off the stock ROM again. Fast load, fast swiping around, the wifi (although still only 2.4) seems to act much better. I have some playing around to do but first impressions are that this is a solid piece of work.

Thanks to the whole team.

---------- Post added at 09:42 PM ---------- Previous post was at 09:29 PM ----------

In terms of the slow download and thought you may have a corrupt image, try running an MD5 hash on the file you have. Shouldn't take long to do and will tell you if you have a bad image or not. The file MD5 hash can be found on the first post of this thread.

I used TWRP 2.8.0.1 today and Odin to load it. Then used TWRP to load the ROM from SD card and have seen success thus far.
[Galaxy Tab 4 Android Development] bingobill:
I do dislike pestering ppl, so just a polite reminder about making available a fix for this issue.

thanks :)
[Galaxy Tab 4 Android Development] g_ding84:
I'm so sorry. This weekend went by too fast. I'll have it up tonight.
[Galaxy Tab 4 Android Development] Fyredragon:
Tsk Tsk, Bad g_ding allowing the weekend to take up your time from us. I am so disappointed :)

[Galaxy Tab 4 Android Development] Ghostrider:
My Tab4 7.0 SM-T230 works well in 5 Ghz. See Screenshot.
[Galaxy Tab 4 Android Development] Afrobaron:
So I have the T230NU, I would hope that doesn't make a difference but I bet somehow it does.

I was surprised when I made my first load attempt that the 5GHz worked, but then I quickly realized I did not wipe the system before ROM install and hence still had all the Samsung bloat in my storage. When I flashed the second time I wiped it all and lost the 5GHz detection in the same stroke.

Am i missing something that I need to do?
[Galaxy Tab 4 Android Development] Ghostrider:
I don't know if it is much of an difference, from T-230 to T-230NU, but by the first new ROM install i cleaned all but the nvm Folder.

I cleaned : Cache / System / Data / preload

The nvm Folder I did

NOT

clean, it seams in there are the Marvel and Audio Drivers. I can be wrong on this but better safe than Sorry.

So I think your cleaning can't be problem.

Thanks g_ding8 and my condolences for your loss.

zip installed ok but it didn't change anything, recent list background is still transparent :eek:
[Galaxy Tab 4 Android Development] g_ding84:
Thank you.

Now I'm at a loss..... ??? I didn't modify any other apks that could control that. The recent list can only be controlled by either (or all) SystemUI.apk, SecSettings.apk, framework-res.apk or twframework-res.apk

So, for it to be still transparent, I'm at a loss for what it could be. I haven't modified anything else other than deodexing all the APKs.
[Galaxy Tab 4 Android Development] Tech 4 9:
So...fun fact. I finally got this rom to work and it's been running nicely ever since. On a hail Mary I added the stock od1 kernel after the ROM for the twrp flash. Don't know if thats interesting or not but this rom wasnt working for me until doing that. Happy holidays!
[Galaxy Tab 4 Android Development] g_ding84:
All tabs are build different. Glad you got it working. :D
[Galaxy Tab 4 Android Development] doctazz:
I'm running mine with this ROM, and beany23's mod of CTz's overclock kernel. Beany23 has the top speed at 1.482 GHz. Beany is trying to run it up to at least 1.586. Makes games run more smoothly, and a few extra fps for video (especially HD). Overall, it's stable but it does eat slightly more battery while active. When idle, it uses less battery than the stock kernel, as it runs down to 156 MHz. :)
[Galaxy Tab 4 Android Development] chrisa887:
i turned your rom into aroma installer, if you want the link let me know. running great for me. nice work!!!
[Galaxy Tab 4 Android Development] nicolos35:
Long time to start

First thanks for this wonderful ROM ... I have installed and my tab is faster and fully operational since 3 weeks. But .. this morning the start of Tab takes a long long time around 4 or 5 min stuck on the Samsung logo. Have you an idea of the reason why it takes suddenly so long time ?
[Galaxy Tab 4 Android Development] mike2nl:
That sounds interesting for noons ;). Have you add oc kernels too?
[Galaxy Tab 4 Android Development] chrisa887:
No I have a program that I use and it turns a non aroma rom into one with aroma. I old probably add that in if there are different kernels for the tab4
[Galaxy Tab 4 Android Development] chrisa887:
I can make one with apps and kernels but it will be a separate zip to flash. Just need to know what kernels will work
[Galaxy Tab 4 Android Development] g_ding84:
That sounds awesome. Yeah I don't mind. I can link it in the OP.
[Galaxy Tab 4 Android Development] chrisa887:
Here is the the rom with aroma

https://drive.google.com/file/d/0B7VAnjymdYaFV0x6c05ELWY4b3c/view?usp=docslist_api
[Galaxy Tab 4 Android Development] Tech 4 9:
Judging by all the kernel talk...I imagine the aroma stuff is just for unlocked bootloaders?
[Galaxy Tab 4 Android Development] thisisapoorusernamechoice:
The only Tab 4 models with a locked bootloader are the AT&T and Verizon models (SM-T537A, SM-T337A, SM-T537V, SM-T337V). This rom is for the SM-T230 and SM-T230NU, so there should be no issue whatsoever...
[Galaxy Tab 4 Android Development] chrisa887:
Should work with anything you can flash, I can make you a zip of different kernels if ya want to try. If it don't work It will just say failed. But if you can flash a rom then most likely you can flash the file I made
[Galaxy Tab 4 Android Development] Tech 4 9:
Ya know...I have to admit..i got my threads mixed up. My tab is only the second device I've rooted besides my s4 so I'm always considering my s4's locked bootloader. ; ) Duh.
[Galaxy Tab 4 Android Development] stevejohnson42:
Slightly off topic .. it is great to see active discussion and development here..it is a nice device , but wish I had done more research to see what was being developed on custom rom side before buying. last time I looked this was only active thread , but a stock rom .. thanks to developer for keeping at it. for me it is not an option due to the sync issuess, but have picked up great suggestions on what to use with exposed so I could tweak the Prism Barebones rom I am using.
