I have seen posts from others where they fixed a broken note by opening the note on another device that you sync your Evernote with, rename the tile or move the note and that fixed it.
Just ran into an issue where the app crashed while saving a note, and now I see the saving icon on top of the note, and if I click it nothing happens except I occasionally get a toast that says saving. I tried rebooting too. Going to try moving it around on the desktop and see what happens after a sync.
Update, editing on my PC by moving and changing the title seem to fix it.
Thank's to kool2zero who posted this reply from HTC because that helped me fix the problem.
Update from HTC regarding using notes offline and trying to sync an bunch of pictures and notes:
I understand that you would like to know if there is a way to retrieve a note that was apparently deleted from your HTC Flyer before it was able to sync. I tried to duplicate this issue by disabling Wi-Fi, creating four new notes with pictures, then reenabling Wi-Fi and attempting to sync but I was unable to replicate the issue. Your best bet for seeing if the notes are still cached somewhere would be to download a file explorer, such as Astro, Linda or ES File Explorer and search the contents. You may want start by looking under SD Card> .data> HTC Notes or if you know the name of the file you lost, try searching by the file name using the file explorer.
I basically went to the .data/HtcNotes folder on SD Card, found the files for my broken note, created a new temporary note, and overwrote that new note with my broken one.
* Create a new blank note on your flyer
* Record a few seconds of voice on that note (optional) only needed if your broken note has a recording on it you need to recover too (this is so it creates the.amr file to replace)
* Plug Flyer into a PC in Disk Mode (or use a file explorer app like htc suggest)
* Browse to .data/HtcNotes directory (see attached screenshot)
* Find the folder and files related to the broken note (tip: the folder should have the same 'modified date' as your broken note)
* Copy the folder to a temporary location
* Find the folder and files related to the new blank note
* Overwrite the blank note files with your broken note files, Note: make sure the filenames of your broken note are renamed to the blank note's filename
* Disconnect from PC and open notes app on Flyer
* You should now be able to open your note and sync it to Evernote.
It worked for me but I accept no responsibility if you loose your notes, any loss of data or any other problems at all if you try this. :)
Hope this helps anyone else who has trouble with notes
