I broke two “tooth” from the digitizer connector CAP (the grey thingy) while trying to change it. is it why my new digitizer doesn’t work too ? or is the new one also damaged because I see some scratch on the ribbon cable… ? thank you all :(
If the latches on the motherboard are damaged, you can always try applying pressure while turning the 3ds on, because that ensures that there is contact. If that works, you can put some paper or tissue in between the connector and housing to keep pressure on the connector
