Here a mini program to change EBR values to alter /DATA partition size.
This type of operation delete all installed apps on phone, and also delete all files in the internal SD card, so before proceed copy all your data to PC or to external SD card. If you have a CWM/TWRP recovery, do a full backup from recovery to external SD card.
To use this tool, you need the 2 file EBR1 and EBR2 from your current ROM. You can get them from ROM update file in FlashTool format (check here on NeedROM if exist), or from a backup with MTKDroidTool.
Run the program, click on button "Select Folder" and open folder in which are files EBR1 & EBR2. Current values in files are shown on the 2 tables.
Now change value in box "USERDATA size". This value is in Mega Bytes. You must write a value lower than the maximum ROM size of your phone. To know which is the maximum size, go to Setting / Storage and sum total size of "internal storage" (storage for apps) and total size of "internal SD card" (storage for photo,music,docs,…).
After change the size, press ENTER to let the program calculate the new values in EBRs tables.
Now click on "Save" and Exit the program.
New files EBR1 and EBR2, must be transfered to phone with program SPFlashTool. Here a tutorial.
Load in SPFlashTool scatter file from your backup or from ROM upgrade file. Deselect all section except EBR1 and EBR2, click on "Download", turn off your phone and connect to PC with usb cable. Download is fast, wait the green circle before disconnect.
It is mandatory now you start the phone in Recovery. Execute a "Format Data", and "Format sdcard" (internal memory).
Restart the phone, after check all is working again, now if you have a CWM/TWRP recovery, restore your backup. Than copy back to internal SD card your backup you done on PC or external SD card, as said at the begin.
