RE: Failed firmware update 2018 02 12 - Recovery Mode v17 - partial screen, fuzzy - CFO
That older update method that uses the "Recovery" screen will run 3 times. (there are 3 files that need sending). Your system only sent the first of the 3 files.
Go ahead and power down the calculator. With it off, press and hold the SYMB key down. Then press and release ON while maintaining down the SYMB key. You should end up in that "recovery" screen again. Now connect it to the connkit once more. It will detect the unit and launch that "updater" again. This time, let it finish the first file. If after 5-10 seconds you don't see the connkit window start another file, unplug the usb on the calculator and then reconnect it immediately. It will then send the second, and after one more plug/unplug do the same for the 3rd file. Once all 3 are sent, you are good and can pin reset again. The calculator will now be fully updated and working properly and you won't need a Windows computer again (unless for other older units). *Normally*, the calculator will automatically switch between files. However, some computer systems with certain Widows updates started causing problems with this. For example, my primary development machine I use to make Prime does it, but none of our test lab units do. I've never been able to figure out why.... From now on though, you are will be good for future updates. The calculator now uses a method that makes it essentially impossible for Windows updates, or changes to drivers to cause problems with the updates. It also lets a Mac update the calculator as well. As to why the screen "got fuzzy", this is because we increased the color depth of the screen so that things like the background image gradients in the plotting apps looks nicer and cleaner. That required a tweak in the "OS" file as well as the calculator application. Since the app is now not matching the OS - it looks funny. Let me know if anything doesn't work for you. Happy Priming! TW Although I work for HP, the views and opinions I post here are my own. |
