How to remove operator name in SonyEricsson phones?

 

I know many people (including myself) have been asking the same question for a long time. Now I have the answer:

Not just removing the logo, but you can change the operator name to whatever you like.

It works with all SonyEricsson phones, from T39, R520, T68, T300, T610, T630, Z600 and etc!

The idea is very simple, but the steps involve patching the firmware and also flashing the phone, so I think it is not easy for normal phone uesrs. What you need are:

  1. A Terminator dongle and a DIV8.4 (flashing) software. This is a unlocking and flashing tool for SE phones. You can easily found these 2 items by using Google or try www.jerrykee.com

  2. Download the firmware you need from "http://www.cellular-support.com/nuke/downloads.html"

  3. Use a HEX Editor, HEXworkshop for example, to find the operator name you like to edit.

  4. If you only want to remove the name, just replace the first character of the Operator Name with "00". For example, in the case of Orange, you can replace "4F" with "00"

    Before

    After

  5. If you want to change the operator name to your own name. Just replace it with your own name by using HEX (not ASCII)

  6. OK, the final step is very important. Each datablock of the firmware is protected by checksum, so once you have change anything, you have to recalculate the checksum again. It will be a long story if I show all the steps of how to calcualte the checksum, so please refer to this article for details:

  7. If you can manage the checksum, save the firmware and flash it back to your phone with the DIV8.4 mentioned above.

  8. I have to remind that, not all operator will work with this trick, because some of them may store their name in the sim card instead of the firmware. Also, some Operator Name may be in unicode, like Chinese, and you have to serach and repalce the original name with UTF8 HEX code.
