B&N Comics do not get DeDRMed properly, resulting in ~2 lines of garbage characters over 2 pages.

Question / bug report

B&N Comics do not get properly DeDRMed. As these comics are not available digitally anywhere anymore, I am very vested to get access to them. Willing to lend books if requested.

I installed Nook for Windows, downloaded files , got the content for the missing rights.xml (see process in prior question from me), and added it as rights,xml to the archive under 2940045395991.epub\META-INF\ I also tried same after removing the permissions section of the XML, as follows:

In both cases, the result is a shortened book of just 2 pages, each containing only a line or 2 of garbage characters. In one of multiple attempts, the cover picture displayed the following error instead of the mostly blank first page:

Doctor Who_ Series III #1 Cover

Been a long time since I had to mess with these so I don't know if things have changed. I found that they decrypted, but calibre's viewer couldn't handle them. I unzipped the epub. Took the full page images and made a cbz. At least that worked for the comics I had.

@ElleKayEm, how did you decrypt the full page images?

ElleKayEm commented 1 month ago

I decrypted the epub with DeDRM. While calibre's viewer couldn't handle the non-standard epub format, I found that the contents were decrypted.

FYSA, There seems to be two kinds of comics books. The older set I have, which nook itself does not appear to be able to open; and the ones B&N sells now, which can be opened only in Nook apps (including for Windows).

I bought a newer one and tried to DrDRM it (also needed to add config.xml). Decrypts but displays only cover and empty TOC

@ElleKayEm, thanks for tip -- I do see them in the newer version. I'll check if they were in the prior version and do same.

@ElleKayEm ALAS, the original comics' jpegs were not decrypted. Reached out to B&N support with expectation of zero help, but maybe maybe they will gift me the renamed/newer versions (e.g., "Doctor Who: The Eleventh Doctor Archives #29"/9781785850783 in leu of "Doctor Who: Series III #1"/2940045395991.

Given Nook cannot open the older comic format and you having provided a solution for the newer format, this issue can be closed. If left open, I'll update y'all on if B&N came through or not.
