I didn’t know that you already tried to contact BenF.
If BenF or someone else provide to me source of last version, I will implement changes and public it with source (or as he wants). Of course, this can be done by someone else. I would like to extend wonderful Benf’s work (he or someone else).
Until then, we must be satisfied with patched version 3.64 APP and 3.53 LIB. I hope without bugs 
See attachment
Here are two files:
old patch - first version of patched firmware
new patch - version with fixed bugs detected in first(old) patch
Enjoy!
