Huawei Honor 9X firmware — download free update to Android 11, 10.0, 9.0, 8.0,7.0,6.0,5.0

Earlier on our website we touched on the topic of changing IMEI on various devices. Including on 3G USB modems
various manufacturers. Today we continue publishing these materials and will look at how to change IMEI on HUAWEI modems.

First of all, you will need Qualcomm Product Support Tools (QPST), you can download it for free from our website here
. Next:

1. Install QPST.
2. Launch QPST Configuration: Start-All Programs-QPST-QPST Configuration
3. Device Manager -> Ports (COM and LPT) Find the port number (for Huawei-3G Application Interface)
4. If there is no port number, click the “Add New Port” button

5. Here select the COM port that corresponds to the 3G Application Interface

6. This is how your modem should be displayed

7. Click “Start Clients” at the top

8. Select “RF NV Item Manager”

9. The following window will appear
10. Click Setting-Comport-Select a port

11. Next click “File-Read From Phome”

12. The process of reading NV item processing from the modem will start
In the displayed result we will not see the item we need (NV_UE_IMEI_I)

13. Click “File” again and select “Read Supported RF NV Items”

Now all NV items will be visible

14. Select (NV_UE_IMEI_I) I have it at number 550

15. Here you will see 9 empty fields on the right side (if you do not have IMEI)

16. Check the “Hex” box and write the new IMEI in the empty fields. But you must write not in the original format (this is not possible 3 44 30 40 85 11 33 67), but in Hex format (this is necessary 8 3A 44 03 4 58 11 33 76)

Important: In the first field, be sure to enter the value —
8

In the second field, the first digit of your IMEI in this form is
3A

In the fifth window, enter one digit of the value (in the original IMEI this is the 4th set of characters, usually tens (10.20…80.90)
In the remaining windows, numbers are entered in a mirror image.
Example: real IMEI — 3 23 54 30 15 61 53 37
Which should be entered —
8

3A

32 45
3

51 16 35 73

17. I MEI entered, click “File” again and select “Write Only Listed NV Item To Phone

All IMEI is installed.

Important: write the IMEI correctly and very carefully the first time, there will be only one attempt, the second time the IMEI will be write-protected.

You can try this with ZTE MF modems in the same way.

And another very simple IMEI method on Huawei modems

IMEI can be changed using AT commands and terminal programs. How it’s done and the commands.

1. The modem must be connected to the computer and all drivers must be installed on it.

2. First, give the modem the following command at^datalock=”code” with quotes, where instead of the word code you write the unlock code for your modem using its native IMEI. This command removes the ban on writing to the modem memory.

3. Then, without turning off the modem, we give the command to change IMEI   at^cimei=”new imei” with quotes, where instead of new IMEI write the one you need.

Enter the NCK unlock code if the modem does not request it.

Download the program
Huawei_Modem_Tool_v3.3, insert the modem WITHOUT a SIM card — if the modem program starts, close it, launch the Huawei modem tool and wait until the modem is determined, enter the unlock code and click Send Unlock code. After this, the modem will be unlocked.

Look at the picture, everything is drawn in detail.

Attention:

After entering the command, all programs should respond OK. This means that the command has been accepted.
