Backup and restore "Entered name is invalid"

[#1]

I downloaded the latest version of "Backup and restore".

When I entered name for backup file, it prompts me the error "Entered name is invalid".

I already tried different type of name. e.g. digit only, different length of name.

Also, I tried to re-install "Backup and restore"

However, it still fail.

Please help. I cannot proceed to do the upgrade.

Hi

Lost contacts are discussed in some threads on this forum, please search to get more background.

Summary:

1. The Backup & Restore application does not backup synced contacts. Contacts that were synced with Google, Exchange Active Sync, Sony Ericsson Sync etc should be restored by setting up the sync again. Note that Google sync is normally enabled by default on Android 1.6.

2. Android has a concept of contact groups. You can select what groups to show. They are not all checked by default. Try playing around with the checkboxes.
For X10 mini & mini pro: They are under Menu->Contacts to view
For X10: They are under the icon with three guys in the top left corner in contacts.

The main things you need to backup are your Apps and Contacts if Backup & Restore isn't working for you do the below

Open phonebook, press the menu key, tap backup contacts, tap memory card, it will tell you its going to create a vcf file such PCM00001.vcf just make a note of what its called

Register with App Brain on the web then Install the App Brain App below, it uses your google account so easy to set up

http://www.appbrain.com/app/appbrain-app-market/com.appspot.swisscodemonkeys.apps

Then run this App and Sync all your Apps with App Brain this will store them on their site

Once both the above are done run the 2.1 update, then after update do the below

Open your phonebook and press menu, tap import contacts, tap phone card, tap Phone Contacts, tap Import vCard Files then OK find the file you just created and select it

this will restore all your contacts

Re-Register your phone with market if you have not already done that then

Install App Brain from the market again open it and reinstall all your Apps from there, if there are apps you no longer want just dont install them and delete from your list on App Brain.
