The FFC connectors soldered on main and control boards doesn't fit perfectly the standard ribbon cables we include in the V5 kit, causing the cable to bent when closing the tonge and potentially causing bad contact or, at worst case, damaging the flat cable.

The reason is we accidentally choose a wrong part number and didn't realize until now because the difference is really small it works most of times. Indeed i never suffered the issue in any build i did here, in zynthian labs, and i did a few ones!

'''Use a cutter or scalpel to cut the 2 tiny plastic bumps that cause the issue.'''

The bumps are really tiny and you probably need good eyes or magnifying glasses. The tool must be well sharpened, so the plastic bumps can be cut will minimal force. Be extremely careful to not worsen things by breaking the FFC's tonge.
