Deep reset

Deep reset is not available on Series 40 phones, since user data and applications on those devices do not have direct access to the operating system, and hence, cannot crash the phone unless it is in bad shape in which case, you should have it repaired.

If you need to delete all the contacts or images on a Series 40 phone, you have to do it manually. The Nokia PC Suite provides a phone content browser that can help you speed up your cleaning procedures.

On a Series 60 device, a deep reset is equivalent to reformatting the C: drive and wiping out all the user data in the phone's internal flash memory. The data on the MultiMediaCard (MMC) card, however, is not touched. You can reformat the MMC card via the Options Format mem. card menu in the Extras Memory menu. You can force a deep reset on a Series 60 device in two ways:

If your phone can still boot up, you can enter the service code *#7730# in the idle screen.

If your phone does not boot into the idle screen, you need to hold the green Call key, the * key, and the number 3 key simultaneously while you power on the phone.

Although the MMC card should not be reformatted during a deep reset, you should probably take your MMC card out of the phone before doing a deep reset to be on the safe side.

You should see the word formatting on the screen during the deep reset.

It is very important that the phone has power while it is formatting. Do not take the battery out in the middle of formatting! In fact, I recommend that you connect the phone to an AC adapter before you do a deep reset.

Of course, after a deep reset "fixes" your phone's problems, you still need to restore some of the user data to make the phone useful again. That is more complex than simply resetting and requires you to plan a backup strategy before you start fiddling with the phone. Backing up and restoring give you the ability to roll the phone back in time to the stable and useable state before your latest failed experiments.
