How to fix retaining flap in 3ds

I opened my 3ds just to swap the housing. After i done everything i pressed the power button and the blue led pops up for a few seconds and turns off with a popping sound. I reconnected the top screen and speakers properly. I kept investigating what the problem was but i found the culprit. I broke the retaining flap on the bottom screen. (The small thin one beside the long one at the bottom) i had to press the ribbon cable onto the retaining flap slot to actually turn on the whole 3ds. Theres picture but touchscreen dosent work and the homescreen is just going everywhere (probably because i disconnected the annalog) Is there a way to fix those broken retaining flaps (those grey things) i lost like 3 of them. The only tools i can try fix thm is hot glue and black and red electrical tape. I'll probably just buy a new NTSC version of the board if i domt fix this.
