MEP code (0 left) on Blackberry Torch 9800 pls help to unlock

You will need to find a shop that offers DM3 unlocking to reset it.

They will need to physically access the device via the USB port.

You cannot do it yourself.

Other than that ^^:
After the ten attempts have been used, you must get RIM to unlock the device.

There are two routes, and only two, to achieve this.

* IF your device is in warranty, contact your service provider technical support. Tell them you have this issue which needs to be escalated to RIM level customer support. I'll warn you that most carrier technical support people will first assume and think you are referring to a device security unlock, and you will need to convince them otherwise and explain clearly what you need. THEY will not be able to help you because the carriers themselves cannot unlock a device which has had the MEP code attempts depleted, and should (and you will need to ask) to have the case escalated to RIM level tech support.
* If your device is out of warranty, contact RIM direct. See the Contact Us information from the website: BlackBerry - BlackBerry | Contact Research In Motion (RIM) The options you want to select to speak to BlackBerry Customer Care are 3 (for inquiries, orders, billing, e-RMA etc) then 5 (e-RMA and Out of Warranty).
