[Prophet] Downgrade/chaning IMEI

---

Hi there,

I am trying to change the IMEI of my telephone, as the compagny I work only accepts calls from particular IMEI's. Otherwise you connect to the helpdesk.

We get our phones from the company (I now have a w800i)

There is a guy who bought a new phone, and swapped his IMEI, and now he can use it.

I want the same with my QTEK s200. After a little research I found out that I have got a G3, which is good.

So I downloaded the aWizard to CID unlock my phone.

Unfortunately, I get a memory write error.
Here is the output of the program:

Initializing............CID unlocking mobile... DO NOT DISCONNECT UNTIL THE PHONE REBOOTS!

Store the generated 'lock_backup.bin' file in a safe place. It can help to restore your device if anything goes wrong.

Its on the 6'th last line.

Next up I download iWizard, I open it, and the program reads out the IMEI succesfull, but it doesn't write.

What to do? Can anyone help me out?
If I didn't supply enough info, do not hesitate to ask for more.

I guess a real solution would be not to change your IMEI but to ask your company's administrators to accept your actual IMEI ?
