[GUIDE] How to resize Data and Internal "SDcard" of MediaTek MT6732 / MT6752 devices



Hello all.

This thread is about resizing split partitions of MediaTek MT6732 / MT6752 based devices.

In my opinion, splitting the internal storage up is one of the most irritating things a manufacturer can do to a device.
With older MTK phones, we had the EBR mod method. Not so anymore, as 6732 and 6752 don't have MBR/EBR but have a GPT partition table instead, which is MUCH better to work with.

How to do the resize

What you must have:

- An MT6732/52 phone with TWRP recovery installed.
- At least 50% battery
- A backup of your internal "SD card" (it will be wiped, but /data will not)
- A brain ;)


It would also be a good idea to have:

- An original stock firmware that you can flash with SP Flash Tools (just in case)
- The Resize Aroma zip attached to the bottom of this post.


The process will take you less than 10 minutes.

NOTE: The userdata partition WILL NOT be erased in this process.

NOTE 2: As long as you have a stock firmware and know how to install it with SP Flash, the chances of a brick are practically zero.


WARNING: Back up anything you want to keep off the Internal SDcard! It also wouldn't be a bad idea to backup /data too, just in case something goes wrong.

Method:

1. Boot into TWRP recovery mode. Choose Install.
2. Find the Resize zip you downloaded and select that.
3. READ the welcome screen!
4. Press Next and choose the new size for the /data partition. You can choose anything from 3GB to 13GB.
5. Press Next and press Start. Wait for the resize to complete (it shouldn't take much more than 30 seconds).
6. Reboot.
7. Enjoy your extra space!


Possible issues:
- "I reboot and get a Damaged SD card notification"
-> Click the notification and click Format.
- "My device does not boot!"
-> Reflash your device with your stock firmware using SP Flash. If you don't have a firmware... Well, you were warned.
- "Partition resize appears to be successful but my device bootloops"
-> This can happen when you shrink the /data partition too much. Run a factory reset in recovery and try booting again.
