DFU OTA

[JIMMY01]

I got an APK developed by my customer. When I tried to select the zip file or bin file and started the ota progress, It appears :

Error: Image TLV trailer does not contain an image hash. 

My target is nrf54l15dk_nrf54l15.  ncs version is: v.3.3

I have no idea about the SDK info for the APK.

That error usually makes me think the file wasn't built as a MCUboot-compatible firmware image. An APK is just an Android application package, so if your customer actually sent you an APK, it won't work for OTA firmware updates on the nRF54L15. Even if it's a ZIP or BIN inside, it still needs to contain the proper MCUboot image with the TLV trailer and image hash.
