Hello folks,
Since I do not wish to create too many threads, I will add requests for assistance to this one singular thread.
So, I've bypassed the registration and loaded a few PDFs, and subsequently installed the KoReader (latest nightly) using the adboot method (now I realise why KoReader is so popular around here

). Somehow, KoReader was unable to even detect CBR files. The CBR opens fine with nickel, but it looks faint. KoReader, on the other hand has the provision to play around with contrast, and I was hoping to load the CBR up, and increase contrast to suit my needs.
OR
Is there a "contrast" hack for Kobo Aura HD, somewhere? Have I missed something, so far?
