This guide will explain how to expand an Android phone's internal storage using Ebr Tweak. It will come in handy when you run out of phone storage space a lot.

What are EBR files and why do I need to modify them


Modifying your ebr in a mediatek device is easy and straight forward. Ebr files store your storage partition in your mediatek device. Ebr separates the internal storage where applications are installed and the usb storage for other files like user data, music, documents, etc.
To extract EBR files, make an MTK Droid tools backup of the phone or extract from the phone's firmware

Where is Ebr found?


Ebr files are found in a stock backup rom using droidtools. It is usually found under your backup folder. Something like mtkdroidtools\backup\device name\ifiles_folder or in your phone's stock ROM / firmware.
 

Steps to increase Android phone storage by tweaking EBR


Ebr can be modified by a file called ebrtweak. To do this:


See the video tutorial below or @ http://youtu.be/k5UspcUtCLE

How to expand internal storage using EBR tweak


  1. It is advisable not to go above 4gb as it is usually unstable to do that. It is used to modify our ebr files 1 and 2
  2. Download EBRtweak @ https://www.hovatek.com/forum/attachment.php?aid=445
  3.  Copy your ebr from your mtkdroidtools\backup\device name\ifiles_folder or the firmware
  4. Paste it in the same folder as your ebrtweak

  5. Run Ebrtweak by double-clicking

  6. Type the option for the storage size you wish to increase to then tap Y to confirm your choice

  7. You should get a success message. Tap any key to exit

    [Image: Hovatek-How-to-increase-Mediatek-interna...weak-5.jpg]

  8. The ebrtweak folder should now contain extra files, the ones with .bak are your original (unmodified) ebr files. What you need to copy now are are newly created EBR 1 & 2

  9. Copy the new EBR 1&2 files into the same folder as your scatter file(s)

    [Image: Hovatek-How-to-increase-Mediatek-interna...weak-7.jpg]

  10. Flash the modified EBR files using SP flash tool . Make sure only two boxes with ebr1 and ebr2 are ticked and you select Download only.

  11. Click download and connect your device powered off

  12. You will see download ok. Power on your device and see your new internal storage partition has increased.

Important Notice
  • This guide will only work on old Mediatek chips that use EBR 1 & 2
  • What you're doing is reducing one storage partition and adding to another. Its however important you don't cut out too much else the device could become unstable (hang / crash a lot) or get bricked
  • You best use only EBR files for your phone model, using another device's EBR could brick the device
  • Its recommended you backup your phone's firmware before flashing modified EBR files so you can easily revert should the process brick your phone

If you keep getting Error: EBR file not found or file size mismatch! then download this EBRtweak and ensure the two EBR files are placed in the same directory as EBRtweak then retry

for sp flash tool to work, you need to first install vcom drivers using https://www.hovatek.com/forum/thread-440.html

It eventually worked out after working around it for some couple of minutes.After flashing the ebr I rebooted my fine and found out I lost the USB storage (default storage space) for all files.I thought for a while & booted to recovery, cleared the dalvic cache,wiped data/factory reset & I rebooted.behold my USB storage was there....... If anyone should encounter such just follow it as I did.we're all learners. Admin thnx a lot.....
