This is most likely true in a sense. Even if the magic button isn't there leaving the battery out for a total discharge will work in some cases. I get this with fancy thermostats at work. Customer thinks its screwed, remove power completely for 10 minutes or so resets the whole thing and it will start working again. While phones are much more complex it is in a sense, a little computer.

It's hard to tell. I did open up my old-man's epic to replace the loudspeaker the other day using this vid:

I have it set to start right where it zooms in without the back plate.

I didn't see any button.

I'd have to agree that the extended battery pull did the trick.
[Epic 4G Android Development] Custodian:
Looked at z back of z phone just now....and I can see the button clear as day! Tiny hole, deep enuff just so the button isn't pressed accidentally...

Here are some pics of my epic. (No button, no hole)
[Epic 4G Android Development] ecooce:
Well from the looks of those photos,the board looks like there could be a button on some phones...

Edit::: but I still want to see a photo of the button from someone that has a phone that has this "button",until then I'm saying there isn't one.

Nevermind,those are only resistors,looked like connection points for a popon button,but I guess a missing button would only show holes for solder points,so I'm gonna stick with no one has a reset button,lol,sorry...
[Epic 4G Android Development] ptfdmedic:
I just got my replacement Epic yesterday. I looked at both and it does appear to be a button. If I pulled the back off (which I'm not interested at all in doing) there would be a hole. Not sure what the "button" part is but it doesn't do anything. It very clearly resembles a reset button. Very interesting find mystery. Thanks for pointing it out. My replacement Epic has a broken speaker and so a BRAND new one is arriving shortly. I'll check that one out as well.
[Epic 4G Android Development] phdeez:
I actually totally bricked my phone this morning. (Running fine, nothing weird was happening, used "Reboot Widget" to reboot it, and it just stayed off - ACS 1.1.0 w/ VisionKernel v1.2). I had powered up/down multiple times since I did the battery meter calibration the other night, so I don't think it was a phone problem. With the power off (obviously since the phone is bricked) I tried plugging in a known working charger with no positive effect.

Anyways, I see the indentation, but I don't see a button per-se. I did try pushing the hole in with a paper-clip for 20s, then the Odin boot (1+Power) and nothing. I've also tried leaving the battery out >15m with no change. Thankfully, a local Sprint store has a replacement Epic in stock so I'm heading over there at lunch (with an appointment) to hopefully exchange it out.

So, with this in mind... can I use a nandroid backup from this phone on another phone (ie replacement?)

--New info below--

Also, it looks like this reboot situation might be caused by the V1.2 kernel and possibly charging the phone for a short amount of time and then rebooting (which I think I had just plugged it back into a charger before doing the reboot). Check this link for a possible solution- remove the battery... press the power button twice, reinstall the battery then try regular boot/download mode.
[Epic 4G Android Development] azyouthinkeyeiz:
Its called the placebo effect...

From someone who takes the phone apart daily, there is no "button".. The hardware reset is preceded by holding the power key for 10 secs with the battery out..
[Epic 4G Android Development] bender beerman:
try removing the battery, then plugging in your phone without replacing the battery, then booting to download mode?

Thanks for the suggestions...

bender beerman: I tried removing the battery and attempted to get into download mode with just the power cable with to no avail. No response at all on screen.

Hypnotic2010: Thanks for the link, but since my phone does absolutely nothing at all- TheBeano states "If your phone screen is always black, that is it does not display the white Galaxy S/Samsung/AT&T logo when you switch it on, then sorry, this jig will not help you." I will keep that handy though if I can't get into the bootloader! :)

Now, I need to search the forum and see if I can find out about cross-device nandroid backups since I have a recent backup that is operational, and Sprint has exchanged the handset at the store.

--Sorry for being OT here... Thanks everyone for the suggestions & help--

[Epic 4G Android Development] epic4GEE:
I'm not 100% sure, but I believe as long as its an epic to epic nandroid it should work,assuming you use the the same version of cwm you use to make the nandroid.
[Epic 4G Android Development] othan1:
I'm a bit late to post this, but here's a nice video showing the disassembly of the Epic 4G. You can see there is no button inside the housing on this particular model. You can also compare the build dates because you get a clear image of the manufacturer's sticker. Hope this is found useful.

[Epic 4G Android Development] ecooce:
That button must be camera shy ;) ...

[Epic 4G Android Development] zvonkorp:
So you believe this hardware button exists despite multiple pictures from different people of their motherboards with clearly no visible button underneath there?

The devs arent religious figures to be held above factual evidence, they're humans just like you and I.
[Epic 4G Android Development] MysteryEmotionz:
I'm still looking for the i9000 thread that made me look for this button. Less then 50% have reported not having this button. Just like this thread. Just cause the people showing pictures don't have the button it dont mean it don't exist. Others have reported seeing this after disassembling there phones some time ago.

There might not have been a hardwaste revision but it has been noted 2 different phones where released on launch day. Done phones where shipped with dg27 and others where shipped with a dh build. My phone happens to be a launch phone that came with dg27 and not the dh build.

Looking at the pictures that where posted you can tell that little dimple on the case was ment for something but not utilized. What other purpose could that little dimple be for. I'm sure samsung casted one shell for are phones. the phones with out the button got a dimple while phones with the button have a straight hole. Its just a matter of finishing the hole instead of casting 2 molds
[Epic 4G Android Development] MysteryEmotionz:
I forgot that there was a 3rd version of the phone released on launch. Some people got a hw version .4 phones.

So the phones with hw version .5 that shouted with dg27 are obvisually earler builds then the phones that shipped with the dh build.
[Epic 4G Android Development] styles420:
Mine is a .5 model that shipped with the dg build, and I don't have a button. It is possible that enough pressure on that spot forces a grounded shield to connect with a component to effectively ground that part of the circuit - in other words, it could be a fluke that this works
[Epic 4G Android Development] ecooce:
Ok,Ive got $25 for the first picture of this button on an epic v.5... Lets put this to sleep already.

I have an openinf day phone. Are we talking about these buttons labeled R1, R2/G, W1, and W2? I don't know what the purpose is, but it looks like I have 4 of these buttons? That sure look like they could reset something if pressed. I am not a techie but they have dedicated slots that look like you reset an old digital watch and are labeled......

[Epic 4G Android Development] thematrixkid17:
The indentation you all see is a mark from the injection molding process. No one has been able to produce a picture of a hole through the housing, nor a button on the motherboard. Not to mention that there are components on the board directly under where the rumored position is...

[Epic 4G Android Development] sniperkill:
I'm not sure about a button there, but so far I've seen 2 different makes of this area. 1st, there's my Epics backside where there's a indentation there with a hole in the middle, 2nd, there's just an indentation with no hole. I for one had the courage to press this so called button with my phone on and off, both in which nothing happened.

Personally, I feel if no one has produced a pic of this button by this time, its just a myth.... A page back mystery stated that "less than 50% have reported not having this button, where the others have reported having it". Now, the ones that have reported NOT having this button, HAVE produced pics. BUT, the ones saying this button exists, have yet to post any pics of it. I'm not saying its not there, im just saying the odds are slim...

[Epic 4G Android Development] hdnet1:
I've ripped apart a more than a hundred Epics at work, I've yet to see a button on the circuit board. It would be cool to have a solution to the 100% brick problem though, had a few show up in the last couple of weeks at work since the 1.2 vision Kernel came out, can't prove that was the cause, but up to that point I'd never seen a 100% dead Epic.

That Kernel has probably cost Sprint a lot of money.

[Epic 4G Android Development] heathmcabee:
My button can beat up your button
[Epic 4G Android Development] jkrough0728:
As much as I wish this was true, I have to agree it is false. No Epic I have taken apart has a button there and the board itself is not designed for a button to be placed there regardless so it wouldn't be on some.

I have attached a pic just to clarify the board has no spot for a button there.

But I would like to figure out your brick fix so maybe go through the steps again without doing that and see what you are doing. Maybe it is something different.
[Epic 4G Android Development] southparkeric:
i would remove battery for a minute

then press the button for like 15-20 seconds

then wait an hour then I would place it in download mode.

this worked for me
[Epic 4G Android Development] southparkeric:
well mine has a button their... so why is it their....? I can see it clearly...
[Epic 4G Android Development] jkrough0728:
Are you sure there is actually a button? Not just the plastic bubble?

Did you take it apart and see an actual button? From my experience with OEM boards, if a button was placed on some, that spot would be empty for the others...
