Thanks Bo and Chaeryeong, I've successfully managed to fix this by removing the residual plastic hooks as they were badly broken from prior opening and used double sided tape as a temporary connector for the top panel and the base. Cheers!
Hello, thanks for the guide. I followed it but had a problem with reassembly, here, would you happen to know how you reassembled it? Whenever I push the top part down, the front panel goes forward so I haven't been able to reassemble it like before
