CRUISER BOX Users:How To Upgrade CID 49,50,51 To CID52 :
Be sure to upgrade the EROM before performing this conversion!
· Attach the phone normally, then go to the GDFS tab,
· from the Modify GDFS options list choose Upgrade to CID52 and press the Modify GDFS button.
· Then turn the phone off (for example by pressing the Finalize GDFS button).
The CID will be upgraded during the next EROM code execution, i.e. during phone startup or boot via DCU-60 (while holding the C key).
