How to flash my sonny ericson w850i using SETool lite

SOURCE: Please help me to unlock Sony Ericson W850i

If the phone lock code has been changed from the default 0000, or 1234, it would require the phones' software be flashed/wiped to factory default. There is no master code that would unlock the phone once a personal code has been entered.
You can try flashing the phone using the likes of wotanserver or davinci, or have it sent to sony ericsson for service.

SOURCE: NEED PUK CODE FOR SONY ERICSON W850I

The PUK code is a code associated with the SIM card and not with the phone.

You have only two ways to get rid of the PUK code. Either you replace the SIM card , or you call phone provider that issued the sim cadr (eg. At&T, Virgin, Tmobile , Vodafone, Telecom etc.)

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.


The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore. d dd
