The C636 dload does in fact work, I've got a C567, and soft bricked. I put the dload folder on an OTG adapter. The trick with the dload folder isn't just simply putting the .App in the folder. It's more complex. Let me get you a link to the one I used (I downloaded it from a Google drive account, unzipped it, then put on OTG w/ thumb drive) booted to Erecovery, with 3 finger solute.
