Hello folks, new to this forum but this seems like the place to get help with my DMH-W4660NEX headunit.  I recently updated the firmware and after still having issues with connections to android auto on my phone, I did a factory reset of the settings on the device via the menu interface.  However, after this the device has entered a boot loop where it flashes a loading screen, the screen goes blank and then the headunit restarts.  No error messages are ever shown.  Do folks have suggestions on steps on how to resurrect the headunit?  I have seen for other headunit models that folks are replacing corrupted SD cards...is this possible with this headunit?  Any help and advice would be very helpful!

Thanks in advance,

Brian

FYI for folks who may have a similar issue...I totally disassembled my head unit and there was no replaceable SD card or other reset mechanism that I could find.   I think short of having someone at Pioneer reset it mine may be bricked.

I have the same problem of you. It's happen after factory reset. Finally, what was the solution, if any, to solve your problem ?

Mine is stuck in a loop now too after trying a factory reset. Any solutions? Seems to be a bug in the head unit itself. Wonder if pioneer knows of this issue

Oh Geez. I just triggered this same problem on my 7600 after a factory reset as well. Anybody have a resolution yet? I'm waiting on support to respond.
 

I'm having exactly the same problem.  Any solutions yet from Pioneer short of a new unit?  I customized my dash to accept the 7600 NEX so prefer to stay with that model head unit vs. switching to different brand. 

I have the same problem with DMH-4660NEX

Did you figured it out?

If there is a boot loop issue pioneer needs to resolve this as its a glitch.  Not the customers fault. They came out with a firmware update that was faulty. The reset button has a purpose and if its not correcting the issue... Pioneer needs to make it right. Anyone call Pioneer and raise hell yet? Stick with my wording with Pioneer and press the issue. I am an attorney.
