I think I figured out the main problem.

Due to wrong flash, PMT changed partition layout and instead of 4GB of internal memory, my device shows 8GB.

Is there any way to read back PMT to change partition layout?

Yes, if you're able to format then download or use Firmware upgrade successfully

Thank you for your reply.

The only way to solve this type of problems with EMMC partitioning is:

Warning: You might kill your EMMC chip if you don't use the right Firmware.

1- Pulling out the EMMC chip.
2-Use an E-socket to read\write to the chip directly.
3- Connect your E-socket to a compatible BOX with adapter.
4- Format the chip and Restore the chip firmware.
5- Flash your device firmware.

PS: This method is not cost effective as you should have access to necessary hardware and if you're not familiar with hardware repairing you might kill your device.

A word of advice:
Give it to support center with peace of mind and you don't end up with a dead phone. (I mean really dead)

I hope this helps someone, so they don't spend hours to find a way to solve the problem.
