[P3300, MDA Compact III ROM Development] Gwystyl:
run ROMUpdateUtility.exe and follow the steps?

perhaps you should read/search some topics on flashing...... what does it do and how does it generally work.

edit: the long version of what I just said (from a step-by-step instruction from way back):

OK, I volunteered... This is a detailed list of steps how I installed a new ROM on my MDA Compact III (CID locked, at least I think so). It worked without any errors or problems. I used PDAVIET Black&Blue v2.0. It was my first flash on my Artemis, so I more than understand your need for step-by-step guide :-)

1. download the file Artemis_USPL.zip

2. unpack into the folder c:\USPL

3. download the rom of your choice

4. unpack into the folder c:\ROM

5. soft reset your phone and have it charged over 50% (I have it fully charged)

6. wait until the system starts on your Artemis

7. turn on flight mode (probably not necessary, but I wanted to minimize any risks)

8. connect your Artemis to PC with a USB cable

9. wait until ActiveSync icon in your tray (lower right corner of your windows desktop) turns from gray to green. If you connect your Artemis for the first time to PC, you do not need to set up synchronization, just click "cancel" on the first screen of "Synchronization Setup Wizard"

10. while ActiveSync icon is green, run c:\USPL\start_uspl.exe

11. a DOS screen will pop up with the text "Initializing: 0.." in the bottom indicating probably seconds from the start (it stopped around 70 in my case after about 1.5 min)

12. DOS screen disappears and PDA Phone ROM update utility pops up

13. at the same time, your Artemis turns blank (orange/green LED turns off as well)

14. tick the check box next to " I understand..." and then click Next

15. tick the check box next to " I completed..." and then click Next

16. a box saying "Verifying information on your PDA..." pops up

17. on the next screen click Update button

18. next screen says "Upgrade to ... image version 9.99" - click Next

19. Next screen says "You are now ready to update..." - click Next, a window with a blue progress bar appears with a text "Updating ROM image..", it quickly runs to 100%

20. next screen says "Congratulations! ..." - click Finish

21. your phone turns on and boots into your old system, however it should be CID unlocked now

22. your Active Sync should reestablish and icon turns green again

23. do not touch anything (phone or USB cable) and run C:\ROM\ROMUpdateUtility.exe (make sure activesync icon is green)

24. PDA Phone ROM Update utility window appears, tick the check box next to " I understand..." and then click Next

25. tick the check box next to " I completed..." and then click Next

26. a box saying "Verifying information on your PDA..." pops up

27. on next screen click Update button (says "Current information...")

28. next screen says "Upgrade to ... image version BnB2.0" - click Next

29. Next screen says "You are now ready to update..." - click Next

30. a window with a blue progress bar appears with a text "Updating ROM image..", your Artemis will have light gray screen with blue progress bar showing the progress of flashing - do not touch anything and wait (it took 2-3 minutes on my 3 years old PC)

31. next screen says "Congratulations! ..." - click Finish

32. your Artemis turns on and starts booting, you can disconnect it from PC now

33. the boot screen remains the same (T-Mobile in my case), so do not panic!! it is normal

34. wait until calibrate the screen appears, calibrate, choose time zone and you are ready to use your new OS

35. let me know if this manual was clear enough, whether it helped you and please suggest potential changes for improvement
