My Iridium 9555 phonebook is unavailable
When upgrading an Iridium 9555 handset from software versions earlier than release candidate HT14004 all phonebook entries will be lost.
Note that the previous public release was HT13001 and the actual one is HT15001.
After the upgrade is complete the user must reformat the phonebook file system to make it compatible with HT15002.
To do this, the user must navigate to the idle screen and enter the short code *#323#
If a user tries to access the phonebook without performing the steps presented above they will be presented with an error stating “My Phonebook failed to initialise. Contact service center.”
The phonebook file system must be reformatted using the instructions above.
