When I issue a power down on my M66 by AT command or driving Power Key, all is working fine and got the messahe NORMAL POWER DOWN
but it always reboot after with all functions activated even if I AT+CFUN=4;&W;Z
to save phone deactivated
Here is the log file

First restart is not the expected issue, but why if I disable phone with CFUN
and save it is does enable phone on restart?
I tested with stabilized power supply lab, 4.2V same issue.
Thanks
