    I have a patched phone (Preware). Ran EPR to uninstall the patches before updating, but didn't restart the phone afterward. Update seems to have worked fine; Could reinstall the (compatible) patches.

    But now my PC seems to needs some driver to be help to connect to the phone. Plugging the phone into the USB cable begins the New Hardware wizard, with the message "windows needs to install driver for reduced CDC abstract control model (R-ACM). It can't locate it, and I can't get the phone to USB mode (though it does recharge).

    Looked through the forums and didn't find anyone with this particular problem.

    Please help!

    Try going to the phone dialpad, and entering

    ##8727277# and make sure they're all turned to "None".

    That Worked!! Thanks!!! .. the USB1 connection showed "Diag" next to it... Changed it none and it works now.. but does require SPC code

    I tried it and I also have USB port set to diag but when I change it to none I am asked to enter a Master Subsidy Lock. Any Ideas?

    there is a company SELLING a driver for Reduced CDC Abstract Control Model, so u could access your pre with diag, or directly to the gps and so on.

    I havn't found a free alternative - anyone who has experiences with that? Is it worth the money

    There's a free alternative in the "Standalone GPS" thread somewhere.

    my phone is also doing this and asking me for a code, saying to call a palm rep to get it. Did anyone get this to work? thanks!!!

    There's a keygen floating out there that you put your ESN/MEID into and it gives you the code you need to enter. You'll probably have to Google for it, it's probably not hosted here.

    Ill let you know if it works! thanks!

    IT WORKED!! I was getting this error for driver when plugging in my palm, I could not use it through the USB and was getting the error message Driver for reduced CDC abstract control model ...I did this ##8727277# and I googled PrePassThroughKeygen and it gave me the code to enter ....made sure they're all turned to "None, now my phone is working !!

    thanks so much!!

    I'm trying to USB plug my Pre and it asked about this driver. Sorry, what is or how should I try this ##8727277# ? Type and send?: USSD request failed. Network failure. Is this for AT&T or Sprint?

    wow! almost solved! code ok. USB / Just Charge finally appears! No another problem (connection refused when trying to install Preware using webosquick install).. I will search...
  15. #15  
    YES! Preware installed after 2 weeks trying to do it... I would like to say thanks to all of you that so patiently answer my questions. (Yes, I press the Thanks button too...). I think I will have to copy and paste this to my open questions so please do not consider it as a spam... It is only to save your time about this subject. BTW the problem was to bypass the USB setup (#*8727277# and google password)! Now entering the Homebrew world...

    There should be a bunch of ports listed, with a dropdown menu if you tap on them. Make sure they all are changed to none. There's not really much more detail that can be given on it.
