Change Kindle DX time wo wireless

Because the jail break doesn't give access to the entire filesystem. Still only the existing public mount. It allows install of bin files from there.
The simplest thing is is to re-enable the Developer's USB Network access and then the entire filesystem can be accessed. Then installing is trivial. It's not impossible that someone can figure how to make a bin file that can be loaded to install an application, but that's quite difficult compared to file access to normally executable parts of the filesystem via USB networking.

Or that someone might create a bin file (or patched firmware) that allows an extra directory in the public part to be linked inside the existing "hidden" filesystem so extra applications can simply be copied via USB storage.

Archos Personal Media Player HDD and Apple iPod HDD where both dreadfully locked down. The eInk Kindles and the average Android phone/tablet are nothing like as bad, especially Android as the user is supposed to be able to install stuff.

Maybe the best advice for old cellular only kindles is to plug it into a charger and leave wireless on for a long time.

Two days with occasional waking. The problem seems to be the Kindles have no off. The guy, after discovering he couldn't really read it, didn't charge it all. I had to have it on charge for a few hours before it would wake. It was still "registered" but the date was 1970, so it hadn't been Factory reset but obviously had completely powered off, not even powering clock. I don't know it's got a real HW clock or uses a deep sleep main ARM or secondary ARM or PIC cpu to keep time, either way needs some power. A deep sleeping PIC cpu can cost 50c and use about same power as some quartz clock chips on average. Any Kindle with poor timekeeping is possibly doing it in SW rather than a cpu interfaced version of a HW RTC using 32.768 kHz. BTW, the decent watches rely on your wrist body heat and a metal back but plastic body to provide a stable temperature so the 32.768 kHz quartz crystal is more accurate. You can compare a drawer in a cold place with your wrist for a month each.
