This is ok. All the PIDs I have seen contain numbers, upper case letters, and perhaps "$" or "*". The "checksum" can be letters.

Since you have a Windows PC, one thing you could try is to register the PC as a 2nd device with your ebook vendor. Then redownload the ebook and confirm that it can be opened by Windows MobiPocket Reader (it will then be in your MobiPocket ebook directory, which is My Documents\My eBooks by default). Now try mobdedrm using the Windows PID, which will probably have a $ in it. Note that Windows MobiPocket Reader can do the registration and redownload for you from many MOBI sites, or you can do this manually via a web browser.

Try a right mouse click or the F3 key.

Hmm... I thought they all had $ in them. Perhaps igor will chime in here.

I can definitely open the files in the Windows Mobipocket software (and could all along)...it didn't even occur to me to try that PID and that is most likely the last "registered" place I had opened any of the files.

I'll definitely try this method next (getting the Windows Mobipocket PID and trying it with that).

Thank you...that was a great suggestion. I'll post back with the results but it may not be today. If it's not today...Happy New Year to all and thank you so much pilotbob and wallcraft for your help thus far.

I'm b-a-a--c-k.....

O.k., tried the command with the pid from my computer, which, by the way, does have a dollar sign in it.

I'm still stuck at the Invalid Checksum PID.

There is definitely no possibility of confusion with letters versus numbers.

Have you tried inputting this instead?

mobidedrm.py nameofbook.prc newnameofbook.prc PID

I have heard people having problems when there is more than 1 PID registered at the store. Try removing your blackberry PID and just having your PC PID in your bookstore. Re-download the book and then try it.

Also, you still haven't shown use the "exact" command line you are using. Can you paste in your command window stuff... or attach a print screen of it?

The attached zip file contains pid_checksum.py. This does not remove DRM, it just checks the MobiPocket PID. Use exactly the same command line as before but replace mobidedrm with pid_checksum or pid_checksum.py. This can also be used to find the right checksum for any 8-character PID, and can be run with 1 argument (<PID>) or 3 arguments (like mobidedrm, the first two are then ignored though).

Alright...the update.

First, thank you for the right click for the paste function in the DOS window. That worked.

Second, I believe that pilotbob may have hit the nail on the head with my problem. I think my books being registered to multiple PIDs is causing an issue. Also, it appeared a couple of them I had redownloaded and I had not yet opened so they weren't registered at all.

In my case I am having to use the PID of my computer rather than the PID of my Blackberry.

Now if I could just figure out how to keep those nice little thumbnail book covers (some stay, some don't)...

Thank you very much to all.

And to recap, in case anyone else runs into this, when converting Mobi DRM to Mobi non DRM, in my case I had to use the PID of my computer rather than the device I read on.

Everything else works as explained in this thread with the command line.

THANK YOU!

Check out the Mobi2Mobi tool for putting the covers back.

cheers

Thank you! Off to do that right now.

I'm fairly new at this, but so far have only been getting a "post not found error" in pastebin. Any ideas?

JSWolf · 01-29-2009, 02:17 AM

Take a look at the blog once again and you'll see a link to a working copy.

nsmith52 · 01-29-2009, 06:04 PM

Thank you. Got it. I guess the posts expire every so often. Thanks for taking the time to put it back.
