Reinstalling the back cover stumped me for a second… If you’re struggling with aligning the top edge of the frame, remember that the camera is going to look off/pointed a bit too low until you actually clip the frame back in.
Really stupid but it was the only thing that tripped me up in this guide.
I was able to successfully use a suction cup towards the bottom of the device (near the USB-C plug) to get it open.
Be careful around the camera. I managed to melt my camera lens getting pieces of a shattered glass panel off.
They sell it on here, although I found mine on eBay.
I was able to open going from the microusb slot and working my way around. The corners are tough, though.
The plugs are annoying to open for the first time. They're shaped like little pegs, but I was able to poke at them with screwdrivers enough to open.
This took a ton of force to remove from the adhesive!
Also I was able to take off the cable before removing the battery.
