Backup/Restore IMEI and NVRAM on any Android device

Backup Android apps

The Android system is highly customizable as even a newbie can manage to tweak his Android based smartphone or tablet. In fact there are various methods in which you can optimize, customize and personalize your device and it is up to you to decide whether to keep everything in a default matter or to go wild. Anyway, if you do want to learn how to become an advanced Android user, then you should start with basic operations. Thus, in that matter, today I will show you how to perform a backup operation in order to save (and also restore when needed) the IMEI and the NVRAM data from your own Android device.

IMEI and NVRAM are keeping extremely important data on your smartphone or tablet. As you might know, if this data gets corrupt or if you lose the info stored on the IMEI and NVRAM partition, your Android device will not be capable to work at all. In fact, you will be facing with a software bricked Android device – you will have to restore your device back to service in order to repair it (most likely you will have to pay for the technical assistance as usually the IMEI and NVRAM data gets wiped out when you perform custom or unofficial operations).

Anyway, my goal is to teach you how to avoid these unpleasant situations by checking how to backup and restore IMEI and NVRAM from any Android based device. As you will see, the backup process can be easily applied, as a dedicated tool can be used in that matter. Don’t worry, the operation is safe and secured and you don’t have to use complex or risky tools. Moreover, we will keep it all official, thus you won’t lose the warranty of your Android device while learning how to backup IMEI or NVRAM.

Why and when should you apply this backup process? As already pointed out, you need to complete this backup operation before applying any other custom or unofficial process. Basically, you should save your Android device’s IMEI and NVRAM data before performing stuffs like: gaining root access, flashing custom recovery images (like CWM or TWRP recovery), installing custom ROMs such as CyanogenMod, AOKP or ParanoidAndroid, flashing custom kernels, overclocking your Android device, removing bloatware and so on. You see, during these procedures, a wipe is usually applied (a hard reset); well, during the wipe the IMEI and NVRAM data might also get corrupted or erased.

What kind of info is stored on the IMEI and NVRAM partition? First, the IMEI means International Mobile Station Equipment Identity and it stores 15 decimal digits (14 digits plus a clock digit). These digits contain the unique identification number for GSM, UMTS, LTE devices so without this data you cannot use your Android device at all. On the other hand, NVRAM (Non-Volatile Random Access Memory) represents a certain memory that retains its contests after switching off a device. It consists of SRAM and EEPROM chips. NVRAM contains data like WiFi and Bluetooth MAC address, Baseband version, IMEI/MEID number and other essential information.

With the IMEI things are easier than with the NVRAM data. Why? Well, the IMEI number can be easily obtained – you can dial “*#06#”, you can go to “Settings – About phone – Status – IMEI” or you can check the IMEI digits on the back of your Android device, near its battery. Unfortunately, the NVRAM data can’t be reached that easily and if you lose it, you can’t get it back. That’s why, a backup process is more than recommended – you just temporarily store the info and restore it when needed, this being only a precaution.

Now, for being able to complete this dedicated backup operation, first you will have to ensure that a computer can be used; your Android device and its USB cable must also be near you. From your computer you should temporarily turn off antivirus protection because security features can interfere with the download process (you will have to download the backup tool on your computer first). Also, from your Android device you need to check the USB debugging option. You can do that only after ensuring developer options, so first go to “menu – settings – about phone” and tap several times on built number. In the end, access “menu – settings – developer options” and tap on the USB debugging option.

I also recommend you to charge your Android device before backing up the IMEI / NVRAM data. If your device will get turned off during the backup process, it might also get bricked, so the best will be to avoid these kinds of situations. In a few words, check the battery status and if the power left is lower than 50% don’t go any further without completing this charging process.

This backup process is a general one, so you have no restrictions – you can follow and apply the steps from below for any Android based device.
