First when I've tried to downgrade from 5.8.11 to 5.7.4 It was successful. Later, I've upgraded to 5.8.11 and I thought jb has been disappeared because I could not access usb net anymore so I've tried to downgrade to 5.7.4 again, but I cannot. The update file immediately disappear after usb disconnected.

170701:000427 OTAController[3330]: I UserstoreScannerImpl:scanFile:filname=update_PW3_5 .7.4_initial.bin:Parsing update file
170701:000427 OTAController[3330]: E BundleValidator:validateBundle:FB02 bundle applied on FB03 bundle:
170701:000427 OTAController[3330]: I UserstoreScannerImpl:scanFile:Bundle validation failed:

Any idea what happened and why was the first downgrade successfull?
