CCX 400 USB update failed

Was updating CCX 400 via USB and upon reboot 'android failed'.  I cannot use volume up/down to move highlight but touch screen scroll up/down works.   However there is nothing to use as a 'power button' to accept the choice.  Upon cycling 'switch hook' about 10+ times the highlighted choice 'turns green' as shown.  Any suggestions on how to boot load and/or force a factory data reset?

Re: CCX 400 USB update failed

Hello @MikeHWCO ,

 

Welcome back to the Poly Community.

This is rather unusual but the Android Recovery is not use. Please try this:

 

  1. Power up the phone, let it boot for just 4-8 seconds and then power off the phone again. That should break the Android Recovery reboot cycle. The important part is for the phone to clear previous recovery reboot command but not to let the phone boot far enough to detect the trouble and get into the Android recovery reboot again.

  2. Power up the phone and start pressing the 4 corners of the phone with 4 fingers every half a second till you see Poly recovery UI and/or Mute LED going through Red/Green/Yellow cycle. Once in the Poly recovery mode let the phone complete the recovery. If after the recovery phone still fails to boot then try the same thing with USB stick containing Poly provisioning setup (000000000000.cfg files and 3111-49700-001.sip.ld)

  3. If 4-finger pressing failed to be detected and you see Android recovery screen again then repeat steps 1 and 2 again.

  4. If this fails please raise an RMA

Re: CCX 400 USB update failed

Thanks for the info but had no luck.  I got to an 'Android Green Person' screen twice but only for a split second followed by a reboot that took 10 to 15 seconds but I ended up back stuck at the Android recovery screen.  I did manage to get past the Android recovery screen once to an 'erase data' yes/no screen but again was stuck with no way to 'make a selection' since there is no power button.  [I have no idea what combination of switch hook flashes, single or multiple touches allowed me to advance at least one screen.]

 

I will get an RMA from our vendor.

 

 

THANKS for your help/respone!
