Here it is as I promised.
This phone (the model with one sim card) is sold as a device with 8GB internal memory. In fact the memory chip inside is 16GB, so we can increase the available internal space.
PLEASE READ CAREFULLY AND IF SOMETHING IS NOT CLEAR DO NOT HESITATE TO ASK.
*** The data on your device will be untouched after this operation. But again please read carefully! ***
*** A good practice is always to make a backup of everything which will be changed. I do it and I've made a backup of the entire internal memory of the device before the start of the operation which is described below. ***
*** At the end of the post there is a link to a ZIP file which can be flashed through TWRP in order to perform the procedure automatically. Also includes a check for the size of the EMMC (as there are devices on which the resizing cannot be performed...their chip is smaller).***
1. You can go to this thread and to say Thanks! @meghd00t as his static build of gdisk is used in the recovery below.
2. What is needed:
- A different TWRP Recovery with gdisk inside. It can be downloaded from here twrp-2.8.7.0-idol3-6039y-with-gdisk.img - md5sum: 66b3f82a3e2e1afe14627b3b900a9319
- (Optional) An SD card for backup of the original GPT partition layout.
- Patience and careful reading.
- The Windows users probably need the drivers from this post, for access to the device in recovery mode.
3. How to do it (the output used below is from the terminal window from which I've done this operation on my device):
- reboot to bootloader:
- start the recovery
- go to the device
- unmount all partitions of the internal memory
- ensure that there are no mounted partitions from mmcblk0. The output from the mount command should looks like this:
- start gdisk
all partitions can be listed by pressing 'p' but we are interested by the last two:
and their information which will be shown by pressing 'i' and entering the partition number:
The information which is needed from the above output is Partition GUID code, First sector, Last sector and Partition name. You can write these somewhere (if your values are different from the above) from where can be pasted easily later (alternatively you can use the scrollback function of the terminal 
).
- if you have an SD card make a backup of the partitions layout (in case that something goes wrong):
- delete partitions 37 and 38:
- create a new partition 37, bigger in size with the same (as before) Partition GUID code, and the same (as before) start sector:
The difference here is in the last sector of the partition 30535546.
- create a new partition 38 with same Partition GUID code, but with different First sector:
Please note that here in the output after 'n' the default first sector is 34, so you explicitly must enter the value!!! As can be seen I've entered the next available sector (after partition 37) 305355547 but it has been corrected automatically to 30535548. So you can use directly 30535548 as a start sector. The last sector is at the end of the memory 30535646.
- write the names of the new partitions:
- if you list the partitions again (with 'p') the end of the table should looks like this:
- now it is safe to write the changes by pressing 'w':
- resize the file system:
... hmm ... let's run it:
... well the resize2fs have some checks and refuses to resize the file system therefore we must force the execution:
The device now can be rebooted and its internal memory will be almost 12GB which compared to its previous size is a very nice upgrade. Screenshots before and after the repartitioning can be seen here.
Update (19.09.2015): This is a link to a flashabable zip which can be used from the TWRP to automate the process. Can be used with any TWRP recovery for 6039.
