🔐 How to Convert IMEI into Hex and Generate AT^NVREX Command

simple Method :

Dificult method:

If you are working with Huawei modems or DC-Unlocker, you might have seen the command:

AT^NVREX=550,8,xx,xx,xx,xx,xx,xx,xx,xx

This command is used for IMEI repair or verification. But how do you convert a normal 15-digit IMEI into the required Hex format? Let’s break it down step by step.

📌 Step 1: Understand the NV Item

IMEI is stored in NV item 550.

Data must be written in BCD Hex format (8 bytes).

That’s why the command structure is always:

AT^NVREX=550,8,<HEX DATA>

📌 Step 2: Convert IMEI into Hex (BCD Format)

Let’s take an example IMEI:

356789012345678

👉 Break it into pairs:

35 67 89 01 23 45 67 8

👉 Add padding "F" at the end (to complete even length):

35 67 89 01 23 45 67 8F

👉 Now flip each pair into Hex (BCD rule):

53 76 98 10 32 54 76 F8

So the final Hex for IMEI 356789012345678 is:

53 76 98 10 32 54 76 F8

📌 Step 3: Build the AT^NVREX Command

Now insert the Hex into the NVREX command:

AT^NVREX=550,8,53,76,98,10,32,54,76,F8

That’s it ✅

📌 Step 4: Verify IMEI

To check the IMEI stored in your modem, simply run:

AT^NVREX=550

It will return the 8-byte Hex value. Convert it back to decimal to confirm your IMEI.

⚠️ Important Note

IMEI change on mobile phones is illegal in most countries.

This method is safe to use for Huawei data cards, dongles, test devices, and R&D only.

Always keep a backup before writing into NV memory.

👉 Pro Tip: You can even make your own offline IMEI → NVREX calculator in Python or Windows batch script. Just enter the IMEI and get the ready command instantly.
