Recently TI-Planet website launched a new version of PDF File Converter for HP Prime, already adapted to the new firmware (10077):

mViewer GX2
https://tiplanet.org/gxprime



Now you can create documents with hundreds of pages without crashing. The entire article on mViewer GX2 (in french) is at this link:
https://tiplanet.org/forum/viewtopic.php?p=200656#p200656

Hello, new official version can be found at ftp://ftp.hp.com/pub/calculators/Prime/

As stated by Tim on http://www.hpmuseum.org/forum/thread-6085.html:

This is a major release with a lot of new functionality, and extensive under the hood work in prep for later things. The marketing "blurb" is as follows:

• Use the touch screen to move and stretch your function plots and see how your changes affect the equation
• Enhanced touch screen curve sketching with cubic support
• Add a picture to the background of any graph
• Draw your own fit with your finger in the Statistics 2Var app
• Improved help throughout the system
• Quality and reliability improvements

Note: Due to a need to format the internal flash structure of the calculator, all data will be lost during this update. Perform a "backup" using the connkit to save your data if there is anything you need to keep. If you click the "backup" button on the update screen and it immediately pops up a "failed" message, just click backup again and it should be fine.

The manuals are not yet ready for posting as they were delayed due to some unfortunate circumstances. On calculator help is up to date however.
