After showing you How to install the MIUI 6.3.17 release, we offer you on our forum the guide to recovering and restoring IMEI for Xiaomi Redmi Note 3, exclusive for the Mediatek variant.
Before proceeding with the tutorial we recommend that you follow it very carefully, as the improper use of the procedure could be very harmful to your smartphone. We also remind you that the staff ofassumes no responsibility for any damage due to the use of this guide.
Before starting, we would like to spend a few words about the EMI, which literally stands for International Mobile Equipment Identity. Each device must have a unique IMEI that differentiates it from the others, and when you buy a new mobile phone you can find this code on the box and sometimes on the receipt. A standard IMEI number consists of a string of 14 decimal digits, accompanied by a number and an additional IMEI / SV check of 16 decimal digits, although the latter usually only appear on new devices. The purpose of this code goes beyond simple identification and its absence prevents the devices from accessing the cellular network.
Having said that, we refer you to the actual guide, which allows you to retrieve the original IMEI code (if you have lost the packaging of your Xiaomi Redmi Note 3) and restore it. The tutorial is available on our forum, where you can follow the updated discussion of the guide and get advice from other users.
