i have the u620 and followed your steps exactly and i got bitpim to recognize my phone via USB as an "other CDMA phone" but when i go to put stuff on it, all the menus, (ringotnes,calander,messages...ect) are locked out and it's like i can't manage my phone at all, yet it recognizes it. Did you have to do anything special to break that lock?
how do you tell which file it's trying to write to? none of the phone info is available and i tried to connect via bluetooth and it still did the same thing. I click the file transfer (both to and from the phone) and all the options are locked out. it seems everyone else got this phone to work so i'm determined to do the same.....hopefully
Don't use bluetooth, its not reliable for BitPim.
What you're saying is that BitPim says that you are connected to the phone but when you try to view files by clicking on that + you can't see anything?
BTW, i tried an alternate method and have the ringtones working for now (drag and dropping them through the file system) but yes, i ask Bitpim to search for phones and it finds my phone via USB but when i bring up the check list to restore or add anything, every option is "grayed" out like it's not compatible for the phone or something. But i've been getting frustrated because it seems so many others have got it to work. I just ordered my USB off of Ebay, could it be i have a wrong cord, even if it's still recognizing my phone?
If the ringtones are working for now, then they'll work forever. Did you get your phone from Verizon? Can you post a screenshot of where the ringtones are supposed to go?
