How to Flash Omnia to DZIA5 on VISTA Here, the steps to take.
- Download official Firmware from Samsung by clicking here and choose Singapore for DZIA5 ROM.
- Download a hex program such as ‘HxDen’. http://www.pspmyspace.com/omnia/files/HxDen.zip
- Enter *#638738#. Select Singapore and then click okay. Make sure you back up BEFORE, because it will FORMAT EVERYTHING!
- Edit your registry, HKCU\ControlPanel\Version\CustomVersion to DZHJ1.
- Now open the Hex program. Open i900DZIA5_updater_vista.exe. Search for i900DZ form the bottom up. Change the result to the first two letters to your phones version. NOT Firmware. So it becomes probably i900XX. Close Hex program.
- Now connect your phone to the PC and wait for it to be connected to Windows Mobile Centre. Then run the update file you ‘hexed’.
- Make sure you have sufficient battery. If the phone and update seem not to begin in 3minutes, reset the phone with your stylus and the update should go normaly.
- Please take care when flashing. IT IS YOUR OWN RESPONSIBILITY (GOOD OR BAD) TO WHATEVER HAPPENS DURING THE FLASHING PROCESS!
This method was successful try out by one of my subscriber on his Windows Vista System. We will not be held responsible if anything goes wrong with the firmware upgrade. Upgrading firmware using Windows XP is more stable than the Windows Vista.
