[Motorola Atrix HD] Hemotherapy:
Because as long as you're careful, it's really not required, if you do unplug the connector, then spend the extra 2 minutes, otherwise why bother?

tl;dr: Don't buy extra tape, it's like the goggles. It does nothing. If you're very careful and cautious, take your time doing the "install" (more like a swap), you don't need to cut, or remove extra bits to install the battery.

After doing the mod I don't know why you would. It serves literally no purpose IMO. The guy below you says it helps secure the backing, but with the bigger battery, it's already as secure as it's going to get once you get the cover back on. Battery ain't going anywhere.

Also, I could just be lucky but I didn't have to do 2 of the things others had to do, first the black casing part on the back, the one with your 10 screws, a lot of us haven't had issues with the speaker connector, so maybe update the post and make it a "only if you need to" thing? It's not manditory that you do the extra steps, IF you have problems with the speaker connector, take it off then and reseat it...People were already afraid of cutting, maybe leave it to those with speaker issues without making it sound like everyone needs to do it? =/

Also, cutting, yeah I didn't need to do that either, and I don't know why anyone ever would.

Here's my steps on how I did my install.

VERY SMALL Flathead screw driver to get the casing off, I would suggest using something more flexible, aka, not metal. If you're not careful you'll cause small markings, IF youre not careful of course...

Undid the 2 T5 screws

Took out the old battery

Looked in shock at how similar the battery size really was, had a wtf motorola why wasn't this in the phone from the get go with a slightly bigger back casing moment

Looked at the black plastic housing so if I had speaker problems I'd know what I'm in for

Looked at the piece of the black plastic housing that people were cutting into to make the battery fit, said screw that

Tried to fit battery into place, wouldn't go underneath black plasitc housing

Held the phone, took my pointer finger, slid it barely under the plastic piece, pulled up to flex the plastic a little (although I'm not entirely sure that's neccessary really because I don't I even changed it all)

Slid top left corner of battery under the dead center middle of the battery area, there's 2 silver diodes or what have you on the left in the right, they make a little canyon type area in the middle, ergo, allowing more room, so I slid the top left corner under.

Rotated the right side in while sliding the battery to the left

GENTLY moved it up under the plastic piece as to not fux with anything under there (I've read the thread and people with speaker issues, didn't wanna be one of them, and I wasn't)

Barely moved it up enough for the copper to line up with the screws

Made some small adjustments

Screwed in the screws

Lol'd at the battery tape wondering why it's even on there from the beginning because it's so snug in there especially with the EB40, it's not budging at all

Thought about removing the tape from my EB20 and putting it on EB40, decided not to

Turned phone on

Went to ringtones to check sound, no sound, had heart attack

Remembered phone was on silent, turned up volume

Sound works.

Put case back on phone, noticed the difference in weight immediately, noticed could barely feel bulge on back of case, Fiance didn't notice it until I pointed it out

Went on to forums to post I successfully installed the EB40 with no extra steps.

Noticed someone posted pics of tutorial finally (yay!)

Also noticed they're advising people to do more work and spend more money on extra things than what is required (IMO of course)

Logged in to write post after wondering if shanghei is battery tape salesman for his day job :p

And here we are :)
