Just be really careful remembering which screw is which. I drew a quick sketch of the bracket, then put the screws in the relevant places. There’s no way I would have been able to figure them out otherwise - my eyes can’t see the difference between a 1.2 and 1.5mm screw!
Well that went extremely well. Aside from getting the tiny screws back in, which are a pain to get aligned on the screwdriver, it was really straightforward.
First time I’ve attempted a repair on an iDevice, and this guide made it simple. Nice one!
