If I re-flash with enable R&D mode and pull the battery at Erasing CMT: 66% the animation dots shows for about 2 minutes and then boot up with the Nokia Handshake with an error code "All telephony functions, including emergency calls, are disable due to communication error. to recover, you might have to reboot the device." In this mode sims is not working, charging is not working and no wifi. If I re-flashed with disable R&D mode the Animation dots appears for about 20 seconds and turn it off.
