A clean flash wipes data - cache and dalvik cache.

Dirty flash is just wipes cache and dalvik cache. Leaves you data intact.

The battery charging logo is controlled by 3minit app.....with this ROM. But since you went back to the stock systemUI....its back to the stock settings.

I would check your USB port for dust and if you have compressed air I would blow it out. Also, are you using the stock charger?

Secondly.....You can always try to reflash just the kernel zip located in the second post. For you since you have the T230NU grab that zip and flash it again. (Wipe cache and dalvik cache after flashing a kernel)

Lastly the stock ROMs are located in the general section. They are full ODIN .tar files.

Full NK2 for the SM-T230NU

Ok I def did the dirty flash because there were remnants of my stock setup there. During setup i wasn't sure if i should restore my backup through google to save myself a lot of time re picking out apps so I did (Mistake). Then the play store started trying to re install all the bloatware I was trying to get rid of in the first place. I already had the kernel dl'd to my sd card just in case and flashed it. Cant tell any difference still says not charging in the settings and the battery logo has the red x through it.. Its the standard cord that comes with it its a brand new tablet just got it about 10ish days ago. I think i need to do a clean re-install and see what happens because anything i care about is backed up anyway.

I have probably a dumb question but Here goes If i flash the stock ROM... will that remove all traces of root so as to be able to get the OTA updates again from Samsung?
[Galaxy Tab 4 Q&A, Help & Troubleshooting] g_ding84:
Flashing the full stock firmware in odin. Boot loader, kernel, stock recovery and system. You can use any (T230 - T230NU) you choose and can take the OTA updates to the newest one. This ROM is based off the newest firmware already.

If you do a full un-root you will still have a custom recovery and missing system apps. (OTA will fail)

---------- Post added at 07:07 AM ---------- Previous post was at 07:06 AM ----------

That's always recommended to do a clean flash. Sometimes you can get away with a dirty flash. (Going from V1.4 to V1.4.5)

I would also check the USB port as well.

Also depends on the apps you want to remove. Which ones do you not use.

Did you restore Skype from titanium backup?

Did you try wiping data and cache from the app? Also booting into recovery and wiping cache and dalvik cache and fixing permissions can't hurt. If you can get a logcat I can see why its FCing on you.

So, I did take the time to try this rom but found I went back to my backup very fast afterwards.

There was simply too much bloat for my liking in this ROM, and bloat such as that battery mod (of which I still don't understand its purpose other than to add a second battery meter on the bar)

What I was wondering is, would it be possible to have it in a AROMA Installer so we could pick and choose what extra apps to have installed?

Huge thanks and just wanted to throw that thought out there!
[Galaxy Tab 4 Q&A, Help & Troubleshooting] g_ding84:
As I always say "what one person calls bloat, someone else might call useful"

That's the whole purpose of the debloater zips i made in the second post. To get rid of the excess...

Each ROM is different and everybody's use and needs are different. For you, you could take out all the bloat from the ROM zip and then flash it.....or remove what you don't use afterwards. I try to keep it at a happy medium for everybody. I can't make everybody happy but I can make it stable and better than stock. :)

I have "the second battery meter" GSAM battery monitor to check for things running in the background....(each update i try to find ways to reduce background traffic to save battery and increase performance) plus it give each user control to see as well and make their own adjustments.

They should work. The only thing with the xposed themes is the layout could be off because of the tablet UI layout "we" have.

Kernel ? but not for Acheron ROM.

I asked this a few days ago in the Prism bare bones ROM thread. I have the SM-T230NU with Prism ROM, and wanted to know which one of the T230NU kernels I could use. I'm asking as I want to have a functioning IR Blaster, but don't want to download the Samsung pack that AL_IRAQI created.

Honestly, you did a great job on this. The only issue i'm having on this tablet is gaming, specifically Clash of Clans.

I'm using Cleaner (?) Master to free up the ram/ boost the app before i play it but it's still pretty choppy during game play.

Any ideas to make it master? S5 is running much smoother and i'm kind of sad the tablet isn't running it as smooth.

comment for 1.7 ROM

This is a great ROM. Tried AL_IRAQI's Prism ROM, then briefly want back to stock. Got 1.7 when I had time a few days ago. Seems to be great in the last 2 days. Was bothered a bit by the Google Play FC issue, but that's OK. Otherwise, it's faster overall compared to stock. To improve battery life, I have Greenify installed. With Greenify, I have about 8-10% more of battery life with the tab 4 left on for about 12 hours. (That means about 50-60% of power left.) I use the xposed module for that app, with all the options checked, and non system apps hibernated. The few system apps that I don't want running are frozen via Titanium Backup. Not much, but it makes a difference for me. If I use it with Power saving, it goes up about another 2-3%.

Not sure I'd ever want to overclock this tab4 7 inch as it gets quite warm when watching movies. It's fast enough for me. This really isn't a device for heavy gaming because of the Marvell GPU. The 10 inch might be better for overclocking as it has the Adreno GPU. Haven't tried the IR blaster yet, but I read that you put the drivers back in for that. Will have to try a remote control app and see for myself.

Great job overall, and I hope the tab4 gets Lollipop ASAP!

touchwiz UI and multi window 1.7 ROM

Will restoring the touch wiz ui restore full multi window functionality for all apps? Curious, as using Wanam Xposed's version seems limiting for me. I do know multi window doesn't work for full screen games and certain other apps, that's fine.

Just noticed you mentioning the custom kernels for the tab 4. If I read dragon correctly, that means I can OC the tab 4 a tiny bit? That's awesome BTW... Maybe I can get Looney Tunes Dash to run at full speed with the OC kernel! Right now I can only run that on my LG Tribute phone. Would be nice to play it on my tab 4! Maybe the OC with a bit of gltools tweaks should do it. =)

I greatly appreciate the work you have done with this ROM. I rooted my SM230NU (degas) in March, and installed one of your earlier releases. It worked great, and the only drawback was that there was no 5G wifi. Since you stated that it was broken, I just waited for a new release.

Then I updated to your latest release using TWRP in May, and still have no 5G wifi. Otherwise, everything works well. Is there something else I need to do in order to enable 5G? I have looked through the entire support threat without finding a solution or any clues.

Thanks for your help in solving this!

Play store issues for custom acheron rom for galaxy tab 4

Rooted my tablet this morning and everything was great. Try to go to the playstore to get some apps and it was giving the whole no connection deal with perfect service. Looked up a few things try to adjust the hosts document but that was filled with dialog the built in addaway put there which can't be removed unless addaway is. Any ideas?
[Galaxy Tab 4 Q&A, Help & Troubleshooting] Mahnsinn:
Hey,

I am pretty new to the whole Root and custom rom thingy. So i decided to give it another try after i softbricked my SGS I in 2012 (and didnt know, that this problem can be solved -.-)

I have a SM-T230, and the Stock ROM was horribly, as it crashed all time for me.

I had quite some troubles installing the ROM. I am going to summerize the problems i had and how I solved them (with the help of this thread and others), maybe it can save time for others, it took me around 8 hours ;).

I flashed the TWRP 2.8.7.0 in the beginning. After that i tried to install the ROM. Strangely the cache/ dalvik Cache/System/Data wipe didn't work for me, which resulted in a dirty install and a non existence of google play store. After i realized I had most likely made a dirty install I tried another complete wipe of system, cache, dalvik cache and data via TWRP 2.8.7.0. This resulted in a Softbricked device :cyclops: (again), luckily i just read a few minutes ago, that there are solutions for Softbricks, so I Odin-flashed the stock ROM, flashed TWRP 2.8.7.0 again, flashed your rom again and... got the same problem as in this post: http://xdaforums.com/showpost.php?p=59560038&postcount=140

Google play services were not up to date and cant be updated due to a "connectivity error".

After that i odin-flashed TWRP 2.8.1.0, wiped system, data, cache und dalvik-cache again and re-installed your ROM.

And finally its working. I am not quite sure what went wrong in the first steps, but it looks like the problem got solved by using the TWRP 2.8.1.0., as i am pretty sure i made everything the same way on the first and the last try.

All in all i wanna say thanks to your great ROM. it works fine, i had no other problems than acore until now, and you already explained how to solve that. Have a beer :)

Maybe i will giving the overclocked Kernel a try, but i am not sure yet. I'll try to learn a bit more about flashing and rooting and custom ROMs on my Tab 4, before going to my SGS6. :fingers-crossed:
