I found an UPDATE.APP file inside of TRT-LX2 firmware ZIP (ROM), but I want to know what does the file do? What does it contain?
`UPDATE.APP` file in Huawei firmwares
Question
Answer
Huawei OTA updates are traditionally slow for various reasons. However, Huawei let's users manually update their firmware manually and this is where update.App comes in. It has the boot and system image files.
User downloads the latest firmware from Huawei website, extracts this update.App and flashes it to update the firmware to the latest. See this blog for the steps. This process may vary for your device and it's best to check on XDA forums to be sure.
Broadly speaking this is the purpose of the update.App, though the process seems to have become more complicated over the years (I owned a Honor 6 phone about 4 years ago)
