Hi, 12.5.4. here. When prompted to update my firmware, everything proceeds as intended (downloads the fw OK, integrity check OK...) then we get to the final popup "are you sure to continue?... device will reboot to recovery and install chosen file...data will not be wiped". At this point, nothing happens when I click YES (does not accept), I can only click Cancel or outside the popup to exit the process. This frozen process seems to be consistently shown even after i) normal reboot ii) reboot into recovery (no option to install there). What shall I do? Help.
