Hi ! I have to admit that it’s been a while since I last opened that sort of device. If I recall correctly, I believe it was on the side of the device, and pushing while applying gentle force on the clips (with a pair of precision tweezers) to release the board was all it took to release it from the frame. See image here ——> https://pasteboard.co/JKpSdcG.jpg -—> What I suspect to be the retention clips is highlighted. Hope this helps ! Cheers !

Whatever works best, but I can tell you that the white sticker can and will be easily ripped out if you pull too hard. The glue that holds the battery in place is pretty solid, so I’d perhaps suggest to heat the glue a bit before making an attempt to remove the battery the way you described.

Interesting, thanks for the update ! Cheers !

If you are replacing the board and the battery, and can reach the retention clips under the board to lift the board out of the case, I guess it could be possible to replace both parts without separating them.

Both hidden screws were holding the battery tray in place. I was not able to remove the battery as described in step 9 before removing the screw from this step

You mention :

"Take care to not touch the LSD face or the inside of the digitizer if they are going to be reused. Finger prints inside the tablet cannot be wiped off after reassembly!"

I wear general purpose nitrile gloves to avoid leaving finger grease ... I learned my lesson after understanding why they wrote this about the wifi shield plates when repairing Iphone 4 : "Before reassembly, be sure to clean all metal-to-metal contact points on the connector cover with a de-greaser such as Windex. The oils on your fingers have the potential to cause wireless interference issues. Do not clean the connectors themselves with Windex."
