Using F2FS:
What it is? Wikipedia

To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.

On TWRP:
Download and install this TWRP version: http://xdaforums.com/showpost.php?p=56085899&postcount=2
Wipe->advanced wipe
Select cache->change or repair file system->f2fs
Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
Select system->change or repair file system->f2fs
--------------------------------------------------------------------------------------------------------------------------------------------------
Tips :

• To activate Developer settings : Settings -> About phone -> press Build number 7 times
• To activate 3-way reboot go to Developer settings and select "Advanced reboot"
• Root is disabled by default, enable it from Developer settings - Root access
• To disable 2nd sim on GT-I9300I add following lines to /system/build.prop :
  

  persist.dsds.enabled=false
  persist.radio.multisim.config=none

Bootloop

I flashed cm12 and forgot to flash gappsso it went into a bootloop. So i went and downloaded gapps and tried to reflash everything once again but it still got me into a bootloop between bootanimation and "Android Apps updating" or something.

I'm going to flash cm11 again an then try to flash again.
Still great work @Rox

Merry Xmas!!!

How i get Start

I have trouble to install CWM Recovery in stock 4.4.4, i follow up the tutorial, but when i try to go up into recovery mode, a green big android logo apears. What can i do.
PD: Sorry for my bad english.

 

[DrilonKS]

Bootloop

I want to know what is your baseband sorry for my bad english.

 

[Rox]

I guess location app is causign bootloop. it is hard to fix if you dont have adb tool ...
I will try to make flashable zip for bootloop fix ..
For advanced users with adb:
1. Boot to recovery
2. Connect phone to computer and start console/terminal
3. Go to mount and storage and mount /system
4. Write this on console/terminal:

adb shell
rm -rf /system/app/com.qualcomm.location 
reboot

On TWRP you can also mount /system, then go to advanced -> file manager and then to /system/app/com.qualcomm.location and delete the file from there. Works for me good luck!

@Rox Any screenshot available?

 

[DrilonKS]

Works

Thank you his work :good::good:

Installed, but with issues

Finally i got the CWM, then install this rom, and get the bootloop, and solve with this commands, but my fone dont detect SIMs and Micro SD, is a GT-9300I Duos.
Sorry for my bad english, maybe is a problem just for my installation. Thanks for this great job .

 

[Ahmed00021]

Well i tried this on my GT-I9300I and as stated earlier i manually removed the localisation file via TWRP and it booted and so far the only problem is that there is no sim card detected (i only use one)
Best regards

 

[samo_say]

Made my Day @Rox :good: :good: :laugh:

THX SOOO MUCH

 

[dannys4015]

The rom works perfectly, there are just a few issues but those are cyanogenmod related. Could be because cm12 isnt even out, I guess. I'll test it more tomorrow. Great work @Rox !

 

[Rox]

Here is also flashable zip to get rid of bootloop

Merry christmas ! :angel:

Hope i will get some gifts from you guys

 

[SKolberg]

Hope i will get some gifts from you guys

Want to, because i know how hard and Time-Intensive Software Development could be. BUT... I don't use PayPal!
Another Option? Google Wallet, Bank Transfer or Western Union???


Merry Christmas!

Same problem here (I9300I)

Ty Rox you're amasing :fingers-crossed: :good:

 

[Rox]

What is problem ? Is 1st SIM card working ? Or there is no sim detection at all .... Also can you tell me what happens if you disable dual sim and use only one - see 2nd post for tutorial how to disable it
