Flipper Zero: Waiting for SD card

Just got myself a Flipper Zero because #whynot.

However, the updating process from 0.6x.y to 0.82.3 was not very smooth sailing:

• First it was stuck in synchronising on the iOS app refusing to initiate the update (had to force quit + reboot Flipper Zero to get it to continue)
• After that, once I managed to upload the new firmware, it was stuck on Waiting for SD card after the Flipper rebooted.

The SD card I tried was an old 2Gb Samsung SD I had lying around (have 3-4 of these).

Tried several times, but alas, until I tried a different SD card… Then the update process went fine and the firmware updated as expected.

So looks like this is a sign the SD card is not properly performing (even though format, benchmark and uploading firmware worked fine).
