Yes, i did that but only appears in the "SD Card" the same thing (memory space) as the internal.

---------- Post added at 12:23 AM ---------- Previous post was at 12:03 AM ----------

I'm thinking in 2 ways at this moment (except going back to stock). If this phone can handle OTG, try to flash the device, if not... Do nothing. And, searching in a way to install CWM (I don't know if CWM exists for this device).

What kind of version do you have ?

Yep sir it doesn't have any kind of bug
I'm trying the next Saturday... I'm giving the results between next week or... Is possible to flash recovery without the OS too? Because it take some time flashing all things again (ROM -> Root -> Recovery) (I don't have a PC, I'm able to pay internet cafe only and the drivers installing is so slow)

Hi again, now the ROM is installed. Here the first results

IMEI Working (SIM + Data too)
FM Radio with bugs: can't record content on air: when I press "Stop Recording" the app stays without response. The application stops responding, starts to give problems with the volume control, in addition to that, other applications stop working as the music player, until finally the message "System UI has stopped responding". It is solved only by waiting for an automatic reboot of the system in a few minutes or doing it manually. Another bug is when trying to change the station manually, there is only the window with the current station, followed by the "Set" and "cancel" buttons. The buttons to change the station are in 2 white stripes. As the version of the application is the same that came in the ROM of CM 5.1 for S3 Neo, I already managed through that menu.
Camera Working (doing basic test only)
Without Gapps installed, the phone can't be usable (can't listen to calls)
More tests can be presented by me tomorrow!

I'm back with the 2nd test day: The ROM is unable to access to the contacts saved in the SIM card (Works in CM 5.1 for S3 Neo, which means that it is not a SIM problem, since also in LOS 14.1 for S3 Neo presents the same problem.)

The option to watch the network's traffic in the status bar is gone, the same with the option for locking apps in the running apps menu (long pressing the home button)

When I activate the navigation bar, the physical buttons are still active.

The alarm works well with stock clock app...

The battery discharges a bit fast for me.

More soon...

Hi, me again with a way to stop (even a bit) the battery drain, related with NFC

SM-A300H USERS ONLY

1. Go to: https://forum. xda-developers. com/galaxy-nexus/help/nfc-service-crashed-continually-bootup-t2123869 (join the link, due the level of my profile, I am unable to post URLs)
2. Then install "NFC Check" and "AIDA64" apps from Google Play.
3. For Verification, in NFC Check, the application identifies and indicates that the phone has NFC but it is off, the rest is not of interest (I do not even remember what else it said :D ) And in AIDA64, going to "System" and sliding, going down to "Device Features" it says something about NFC
4. You must have Root activated and you must install an advanced File Manager (Solid Explorer recommended)
5. In the link there are instructions with files to be deleted, in addition to following these instructions it is necessary to take into account that, in this ROM, some of the aforementioned files do not exist with the exception of "/system/etc/permissions/android.hardware.nfc.xml" (which must be deleted) you also have to go to the following addresses and delete the following:

1. Go to /system/etc and delete libnfc-brcm.conf and libnfc-sec-hal.conf
2. Go to /system/etc/permissions and delete android.hardware.nfc.hce.xml
3. Go to /system/priv-app and delete the "Tag" folder. Don't worry for their content.
Go to the build.prop and search for this line: "ro.nfc.sec_hal=true and change to " false"

Returning to the link, more text appears in the instructions, some directories as files mentioned from "KEEP THESE" have not been tested for elimination (it could probably improve the battery life), with the above means that it is under exclusive responsibility of the curious to prove if the elimination of said files entails side effects, this despite the fact that the thread is old and is made from the Nexus forum but we must not give confidence about that.

Now, going to the notification bar, the NFC button has disappeared, the "NFC Check" says "No NFC module was found on your device" and AIDA64, the NFC "features" is gone.

That should work to decrease battery drain though :fingers-crossed:

Thanks a lot for your work!

Tested on A300F, unfortunately I can't turn on the wifi.
I tested some fix like this but without success.

After the warning given previous posts based on the instructions provided by the author of the instructions from the "KEEP THESE", I have decided to test this precaution by eliminating the following libraries and files:

Go to: /system/etc/permissions/ and delete com.android.nfc_extras.xml
Go to: /system/framework and delete com.android.nfc_extras.jar

in this ROM, from the address "/system/lib" there are two different files that the mentioned libnfc_jni.so, these are" libnfc-nci.so "and" libnfc-_nci_jni.so ", both should be deleted. Based on the file libnfc_ndef.so must be kept for anything, because in the ROM LOS 14.1 installed in the S3 Neo if it has that file, and according to the post of the link says the author of the instructions that brings conflicts with the Bluetooth, I decided not to take another step forward.

Now I'm looking for information on some solution to the problem of FM radio recording, which by the way, not even Shazam works, probably also requires the same to identify the music, and as it can not, presents almost the same problems as if he were recording from the radio application. Even, as I do not use ANT+ I also looked for information where I can safely delete the service

I had wakelock on my A300M and I saw NFC service on battery stats, so I renamed nfcnci.apk to nfcnci.apk.bak in /system/app/nfcnci/ and the wakelock it's gone :good:
Edit.
Another important thing, I disabled Adaptive Low Memory Killer, because all the apps and chrome tabs were being killed in background

Hey!
Thx for the detailed explanation @Beatz106.
Can someone explain to me how those codes or sections are responsible for the battery drain? For example: why should system/etc and delete libnfc-brcm.conf and libnfc-sec-hal.conf help? What exactly is prevented or avoided and what is libnfc-brcm.conf? I get that it has to do something with NFC but why exactly or better what does the NFC do that triggers the battery drain?

Hello, i just installed the latest version of the rom, coming from samsung stock firmware, for the FU variant.
Everything during installation went good, but i can't get nor wifi or cellular data to work.
Does there's a specific fix for this? Or maybe i forgot to flash something first, like a kernel or samsung firmware?

FIXED: For the cellular data bug, just reboot the phone. It will disappear by itself.
For the wifi, i needed to flash the latest stock samsung firmware via Odin first, and just then flash the Rom. That fixed it.
