W995 debrand using customize_upgrade.xml ?

I flashed my phone with this :
1. (FW) W995i_1215-7995_Generic_R1GA026_Red53.rar
2. (LP) W995i_1215-7993_WestEurope_R1GA026_Red53.rar


Now if i put customize_upgrade.xml in tpa/preset/custom..

customize_upgrade.xml code :

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<customization>
  <info>
    <cda-number>1209-4784</cda-number>
    <cda-revision>R6A</cda-revision>
    <created-by>bboyzahid</created-by>
  </info>
</customization>
