Sometimes, i found that my firmware still at the old version after update complete, there is no any error.It same happen on use Android-nRF-Toolbox to update firmware.

code:

implementation 'no.nordicsemi.android:dfu:1.9.0'

val starter = DfuServiceInitiator(dfuDevice.address)
.setDeviceName(dfuDevice.name)
.setKeepBond(false)
.setPacketsReceiptNotificationsEnabled(true)
.setPacketsReceiptNotificationsValue(1)
.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true)

starter.setZip(savePath)

starter.start(context, DfuService::class.java)

test phone: Redmi Note 4X Android 7.0

Hi,

Can you try the _debug version of the bootloader which has logging enabled over RTT and check if there are any errors messages? It may be the post-validate step that fails (verify hash of image). Also, does it only happen with this particular phone?
