I noticed that the wiki and your post here recommend not going over about 9GB. However, just for fun, I tried editing the eMMC beyond this recommendation and tried reflashing.

First I tested the waters with 10GB (10240) and it works.
Note: that there is a 30-60 sec delay during intiial eMMC flashing, I've noticed a bigger opt partition takes a bit longer so don't assume it's locked up, it does resume after a bit.

So after realising the 10GB was flashable, I increased it to 16GB (16384)

When I did this I moved the two characters after the 2048;
In hex editor 000000E0h looks like this:

Code:

The original 2GB eMMC will have:
000000E0 20 32 30 34 38 3B 0D 0A 09 09 66 73 5F 74 79 70
So for 16GB, I changed this to: 
000000E0 20 31 36 33 38 34 3B 0D 0A 09 66 73 5F 74 79 70

I'm currently using the 16GB partition.
