Dear Sirs, could you please help me?

Dear Sirs, could you please help me? I’d like to restore IMEI after flashing the ROM on my Zeblaze Blitz/Lem3. Could you give me advice what should I perform to restore IMEI? The watch-phone Zeblaze Blitz/Lem3 is rooted.

You can check with the manufacturer here https://plus.google.com/107705277079377379833/posts/PiUfKutgGgf

To be honest though - the Blitz may work in a different way in which case you need to contact the supplier.

Dear Pablo, I appreciate for your advice.
