4. Finding the Correct Update File
This is the hardest part because ZTE does not publicly host firmware for end users. Here are safe sources:
- You must download the correct
.binor.imgfirmware file. - Source: Only download firmware from your ISP’s official support page or the official ZTE support portal. Do not use third-party firmware as it can "brick" (permanently disable) the device.
