Firmware update by Bluetooth not working

Due to lack of authorization to download the firmware update on my laptop, i tried to do it by bluetooth with IPHONE 13 mobile app. I can connect Flipper but i cannot update firmware as “firmware version on your flipper is not supported. Please update it via PC”

Having not a personal PC to do it, how can i update my flipper? I am stuck :frowning:

Sadly the first update has to be done via qFlipper on a PC, there is no other way to do it
