its ok i found out how to do it after many flashes...

i downloaded the original optiflash, not a specific model optiflash (eg. NOT e900 optiflash)

then followed these instructions:

1. Install the USB driver for the cable.

2. Launch Optiflash and click on "Options > Settings > Generic"
- Select "Customer T: Customer T: D830/D840/E900 (USB)"
- Set "Flash Erase Passes" to "1"
- Set "Operation Passes" to "Default"
- Uncheck all checkboxes except "Differences Only", "Erase All Unused Regions" and "Extended Protection".

3. Select the tab "Read" and make sure that under the "Read Ranges" there is "0x20000000 - 0x21ffffff" because if it isn't, it may wipe your imei. You can check your imei by typing *#06#.

4. Select the tab "Flash and Verify"
- Browse to and select your *.s3 firmware file

5. Select the tab "Default Contents"
If you have a file *.cts with the firmware *.s3:
- Select radio button "S-Record with Contents"
- Browse to and select your *.cts file

If you do not have the file *.cts:
- Click on "S-Record only"

- Click "OK"

6. Connect USB to device

7. Remove your SIM, your microSD card and the battery from the phone which will turn the phone off. Leave the USB cable in.

8. Whilst holding down the * key on the phone, briefly press the ON button. Your computer will recognise the device as Samsung USB Mobile.

9. Return to Optiflash, click on "Options > Settings > COM Port"
- Select the COM port your phone uses. If you are not sure, you can find out by: Control Panel > System > Hardware > Device Manager > Ports (COM and LTP).
- Select "921600".
- In Second COM Port select "none"

- Click "OK"

Lastly, click "Flash"

The flash procedure takes approximately 15 minutes (on mine it was 27 mins) and will be finished when the message "All is Well" appears above the green progression bar.

A full reset should not be necessary once the firmware is upgraded, however, if you want to do it type *2767*3855# then wait one full minute before you restart your phone.

To check your existing firmware type *#1234# into your handset.

If your phone restarts in a different language follow the language selection process:
MENU (left touch button) > SETTINGS (bottom right icon) > PHONE SETTINGS (2nd option) > LANGUAGE (1st option)

Hope this helps some people
