Unfortunately, none of the solutions listed in any place worked for me (permanent solution). What I mean by that is, the airplane mode got turn off somehow while playing with safe mode. But after a couple of restarts, the airplane mode gets turned back on.
As mine is still under warranty took it to a Lenovo Service center and checked with them. They confirmed that this is a motherboard issue and it will have to be replaced. I got mine during the first flash sale in May 2016 and looks like this problem is there with that batch of phones.
Try opening *#*#4636#*#* and changing band ti your native country. I know you would have already tried it.. Just in case you forgot or it helps. ?

Just reboot your device into fastboot mode, connect it to the pc and run this command in cmd :
" fastboot -i 0x17ef oem unlock-go "
BEWARE!! THIS WILL DELETE ALL OF THE INTERNAL DATA.. BACKUP IF NECESSARY..

./fastboot -i 0x0fce oem unlock 0x Invalid option error

I'm trying to flash a custom rom to my X Compact. I'm using Mac OS with the latest release of ADB platform tools.
Whenever i try to input ./fastboot -i 0x0fce oem unlock 0xmyunlockcode i get a -i invalid command error
Usb debugging and oem unlock in my phone are set to on and i can see the phone when i enter fastboot devices.
What's the problem here?
Thanks.

Never used fastboot on a Mac, but I wonder if trying a different fastboot version might help, or just type fastboot help, and see options. Maybe what used to be -i option has changed in newer version...
