Hi,

After a a good few hours tinkering we got 2 samsungs flashed successfuly heres how.

you will need mktvia.exe a revised version of mtkflash. We got it by following links from posts on this site.

1. firstly make a bootable pendrive using the HP utility and copy the extracted mtkvia files to the root of the pendrive.

2. boot the PC to the Bios. we disabled all the IDE channels and ensured that the bios SATA was on and in IDE mode. also set the boot priority so it'll boot off the pen drive.

3. sit the 360 on a static bag and connect the SATA1 from the PC to the samsung drive (make sure everything is switched off at this point) attach the power and AV cable to the 360

4. boot the PC to dos from the pendrive

5. once at the command prompt power up the 360 using the eject button

6. at the command prompt type "mtkvia r /m original.bin" (without the quotes) we found that this actually takes two attempts. the first time gives "no drives found" just retype the command and you should be reading the firmware from the bios. once done mtkvia will tell you to reboot the PC

7. power everything off (PC and 360) and remove the pendrive.

8. boot to a copy of windows (we used a second machine) and insert the pendrive.

9. open up your hex editor and load up original.bin from the pendrive

10. use the goto function and goto hex 4000

11. then use the select block function and enter the value of hex 400 (this selects a block of 400 @ point 4000)

12. choose copy to clipboard

13. load the xtreme33 firmware into the hex editor. Again goto hex 4000 and select block hex 400

14. paste the clipboard into that block of 400. your original key from the original.bin should now be pasted into the xtreme firmware.

15. select "save as" and save it to the root of your pendrive as "modified.bin"

16. remove the pendrive making sure you close the device from system tray to prevent any loss of data

17. with the pendrive in, boot the PC that has the 360 attached to it to dos

18. once at the command prompt switch on the 360 wait a few seconds

19. type "mtkvia w /r modified.bin" again this might take 2 attempts. once its going you will see it writing to the drive and then mtkvia will tell you to reboot the PC.

20. turn everything off. disconnect the 360 plug in the internal SATA cable and go test it.

thats it. your backups should play just fine. it took us ages to get a mtkflash to werk properly with our chipset. once we had access to the drive we tried to use the routine that comes with xtreme to copy our key to the hacked firmware. This wouldnt werk for us. when we booted the xbox wouldnt recognise any discs. even genuine ones would not boot. we also tried the autoflasher method, exchanging our mtkvia.exe for the mtkflash thats in the package. this didnt werk either. although the 360 would still play original discs. The only way we found to do it was to manually patch the firmware. Although it may look daunting its really very simple. Once you have done it once you will realise that its even easier and quicker that doing a hitachi.

hope someone finds this helpful

kind regards
