DFU problems on Huawei devices Android 9

[xiaochenMate]

Hello, I use your DFU SDK on Huawei devices Android 9. When an interrupt occurs during the upgrade process, the exception "device returned error after sending file (error 6): operation failed" is thrown. The specific log is as follows. This problem must occur on Android 9 Huawei devices. Can you solve it? Thanks！

Which version of the library are you using?

[xiaochenMate]

There are problems with both old and new versions. The version I used about two years ago had problems, and then I updated it to the latest version. The same error was reported. Only Huawei's Android 9 and some Android Q had problems. Everything was ok with other mobile devices，thx for your attention

[QuentinFarizon]

I have the same issue on a Huawei P20 pro CLT-L09, Android 10 First connection works, then the dfu library does not send any progress and eventually disconnects.

I have tried with dfu library versions 1.11.0 and 1.11.1

I'm not sure how to get the logs of DfuImpl like above, I don't have them in logcat by default

[QuentinFarizon]

I get the same issue also with a Samsung 10, SM-A750FN, Android 10.

[glailton-ia]

I have the same issue on a Huawei nova 3i, Android 8.1.0 In my case I am trying to update using a .hex and a .bin file, sometimes the .bin file works fine, but when starts the .hex file always fails. I am using dfu library 1.11.1.
