Since my carrier-customized phone is locked, I found firmware online. All the following firmware is free.
Please confirm that your model is ZXHN-E2633. The firmware cannot be rolled back, so please decide for yourself.

Please restore the factory settings first.

For Lanzou Cloud, you need to unzip the zip file. The firmware for flashing should have the .bin extension.
Access the default management address http://192.168.10.1
Simply upload the firmware for flashing and upgrade.
Note: Do not power off during the upgrade process, as it may brick the device.

After about 3 minutes, a WIFI named CMCC-XXXX will appear. At this time, the gateway address has been changed to http://192.168.5.1. The management password is on the sticker of your router. Access this address and change the WIFI name to the one on the sticker. Changing to a different name may cause failure. You can use the ZTE Smart Life app to connect to the CMCC-XXXX WIFI for binding, and then proceed with the reconfiguration.

I'm not sure about the following tutorial. If it still doesn't work, you can try poking the RESET button and then access http://192.168.5.1 three times to repeat the process.
