The legacy guids are e.g. here https://github.com/NordicSemiconductor/Android-DFU-Library/blob/release/dfu/src/main/java/no/nordicsemi/android/dfu/LegacyDfuImpl.java and secure ones here https://github.com/NordicSemiconductor/Android-DFU-Library/blob/release/dfu/src/main/java/no/nordicsemi/android/dfu/SecureDfuImpl.java and both look different.
EDIT: removed stuff, it seems like it matches the legacy guids after all
