Even rebooted my phone, but no joy.
Software needs firmware (the interface that controls the hardware) to run - firmware does not necessarily need any software. All the firmware I wrote over the years needed no extra software to run - it was one and the same. This may also involve turning on or off certain hardware options that are “baked into” the hardware at manufacture.
(1) use them
(2) set them into the case
(3) charge tgem
(4) check update status every 10 minutes by opening the case, still charging, just opening. Et voila finally it appeared.
