Honor X8 TFY-LX3 IMEI Repair & No Service Fix – QCN file download

The 2016 Honor 8 is still the favorite of many, as it was praised for its neat design and great dual cameras. But as these phones get older, a very annoying problem can arise, that is: total loss of network signal suddenly, displaying the “No Service” message permanently, and also the possibility of corrupted or null IMEI numbers. If your Honor X8 model TFY-LX3 has come to this point where it seems to have forgotten everything, you are most likely facing a corrupted QCN file. This article is meant to be a complete guide from diagnosis to the probable remedy.

Understanding the Core Problem: The Corrupted QCN File

Before going to the solution, it is necessary to understand “why” the “No Service” error occurs.

What is a QCN File?

QCN denotes Qualcomm Calibration Data. It is a very important file that is stored in the part of the phone where the modem is housed (since the Honor 8 is the one that has a Qualcomm processor). This is the file that holds all calibrations for your device’s radio, such as:

IMEI Numbers: The unique 15-digit identifiers that allow your phone to be recognized on a mobile network.

Wi-Fi and Bluetooth MAC Addresses: The unique identifiers for your wireless connections.

RF Calibration Data: The exact data that is used for the setting of radio frequency communications and making sure your antenna talks efficiently with the base stations.

Once the QCN file turns out to be corrupted – from a software update gone wrong, or a ROM flash gone bad, or just the aging of the software – the modem loses its default configuration. The phone will be that one which it won’t be able to connect to any network making it essentially a Wi-Fi-only device.

The TFY-LX3 “No Service” and IMEI Unknown Issue

For users of the Honor 8 TFY-LX3, the indications are obvious:

The phone stuck on “No Service” or only allow “Emergency Calls” even  you put in a perfectly working SIM card.

If you look up the IMEI in Settings > About Phone > Status, you will find it either as “Unknown” or a string of zeros.

Moreover,  IMEI  checked through the *#06# call cannot found.

The manual network search either fails or shows available networks but does not allow you to connect.

If this is the case, then try it again with a standard reboot or factory reset, but they will not get you any result. The essential data the modem itself  broken and to rewritten.

The Solution: QCN File Restoration

The Correct QCN File for TFY-LX3: It is the most important part of this decision. You have to get an absolutely clean and functional QCN backup from a perfect, fully updated Honor 8 TFY-LX3 device. A QCN from another type of model (like L04 or L14) can only worsen your situation.

QDART Tool (for IMEI Rewriting): The IMEI on the donor QCN is different from the one on your phone. It is illegal and unethical to use a stolen IMEI; therefore, rewriting with the original of your phone is necessary. The sticker under the battery (which requires careful removal of the back glass) or the original box can tell you what it is.

Qualcomm Drivers: In order for your PC to detect your phone correctly in EDL mode, it must have the right drivers installed.

A USB Cable and Patience: It is a complicated and risky procedure.
