Tagged: M5X firmware update IMEI
I have read the tutorial for the update of the M5X tablet to the new firmware.
The tutorial is clear, but at the end of it there is a point to fix the IMEI with the tool "SN Write Tool".
Is it necessary to perform this step to fix the IMEI?
If I don't fix the IMEI, do I lose the internet connection with a 4G SIM?
I have never made a firmware update, I would appreciate your help. Thank you.
you don't need to re-write the IMEI number unless you're using Format-all-and-upgrade option when flashing!
