I thought you had to be rooted to use adb??
Is the Kobo that works for ptsenter the same version Amazon has now? Maybe freewarelovers.com has an older version.
If the problem is memory, can that be solved by rebooting, or shutting down unnecessary apps?? I usually just give up when I get that message, or find an older version or another app that does the same thing, but if it just needs more memory -- do you mean available memory, or system memory? Sorry -- stream of consciousness!
Is there a fix that doesn't involve rooting?
