Sony Ericsson Aspen hard reset

Restore Aspen M1i phone to factory default settings

Restoring your phone can be useful if you lend out the phone or just want to restore your phone to factory default settings and delete all user data, such as contacts, messages, and downloaded games. Remember to backup Encrypted files before you use Master Reset, or update the ROM system
software, to be able to access the encrypted files on the storage card afterwards.

To reset the phone to factory default settings:

1. Remove the battery cover and the stylus. Locate the small hole (see picture).

2. Press and hold the stylus into the slot below the battery to the right.

Insert a thin object into the hole and press down briefly.

3. The phone restarts.
The content of your phone will not be deleted.

To reset the phone to factory settings and delete all phone content, such as contacts, messages and downloaded games:

1. Tap the Start icon > Settings > System > Master reset.
2. Enter the code.
3. The phone restarts.

Note: When resetting the phone to factory settings, you may lose content that was in the phone when you purchased it.

If nothing works: As last resort do a Sony Ericsson phone repaire with PC Suite. Use this method to hard reset AFTER INSTALLATION----> TOOLS > PHONE REPAIR
