[Q] Epic 4g won't turn on - Epic 4G Q&A, Help & Troubleshooting

My Epic won't turn on in any way. I can't get into download mode, can't get into recovery, can't boot in a standard way either.
I was in the middle of trying to Odin back to stock, and it wouldn't finish the download mode. I tried to flash one of the EI22 tars on the forums here, and it wouldn't finish. I tried the standard stock EC05, and it wouldn't finish either. I had to pull the battery/cord multiple times. I tried with different ports on my PC, different times using Odin, everything. Nothing worked.
So at some point after all this, it refused to go into download mode. In fact, it refuses to do anything at all.
Anyone got any advice? I'm at wits end.

Take the battery off. Make sure no cords are connected to the phone. Keep the battery off for about 5mins. Press and hold the power button for about 15 seconds. The put the battery back in and try booting into download mode.
Before u do any of these steps. What data cable are u using? The one that came with the phone, or another one?

What version of odin are u using? Try using a different version of odin.

Odin 1.85
Stock data cable.
Tried the battery out thing, but it didn't work.

Ok...so that u know, u can't use the stock data cable, its generic...u need a thicker cable , like a blackberry one. Not for to get ur phone back to life. On the back of ur phone with the battery cover off. There is a tiny whole, that's a reset button. With only the battery in the phone, place a paperclip in that hold and press it for 30 seconds. Then pull out the battery, then put battery back in. Try booting into download mode. See what that does

Lol the mythological hole is back!!!!! Just leave the battery out for a bit and hold the power button with the battery out for about 20 secs to get any left over charge out... with battery and sd card out hold down the power button and 1 key and plug into your computer while holding down and that should get you into download mode.... for future reference I have taken MANY epics (over 30) and there is NO BUTTON under that hole... no spot for a button at all... there is no hard reset and this is a myth... the people that have said they have gotten their phones back working after pressing this non existent button only got it back into download mode because they left their battery out long enough for it to reset itself... the "button" had nothing to do with it... disagree? Take your phone apart and take a pictue of the button... not the hole but the actual button... I guarantee you its not there!

Interesting... I have never done that form of a hard reset, but a friend of mine has. There is videos on this all over youtube on this. But if u there isn't, than I really can't argue with that. Since I have not done it myself.

Watch those videos and send me 1 where they take the phone apart and actually sow you the button... its not there trust me... that being said though, it is extremely hard to completely brick this phone... not impossible but damn near... almost everything you do to this phone it can be recovered if you follow the sticky in developement entitled how to recover from a soft brick or bring it back from the brink... go there and do everything it suggests... btw please search before posting a new thread as this is in a sticky and tons of other threads... please search first!

Okay so I left the battery and microsd card out of the phone for like 3 hours, came back and put it all in and it still won't turn on.
Is it really no good?

No what you want to do is leave the battery and sd card out and press and hold the power and 1 button and plug into your computer to get into download mode. The odin the ec05.tar with victory.pit and check repartition and reboot and you are good to go

Should have done this from the begining you take the battery and sdcard and plug in the phone to the computer using the computar as the power source and go into download works almost everytime unless you slid brick it. If this doesn't work go online and buy a download mode jig there like 8 bucks or you can find a tutorial to make one..... this will reset the odin counter ( I think) and jump you into download mode.

Guess what gentlemen, that method didn't work for me before. I had to literally keep the battery out for awhile and then place it back in. I will tell u why. U don't know how stable the power source is on a usb port. Take a cable and plug it into a camera or something, start wiggling it just a little..it will start to flicker (turn on and off)...reason being...wear and tear on the port. That's why I never state that method.. I say this to u with all respect given.
Sent from my SPH-D700 using xda premium

And the port can send a micro-static charge through the cable and right to the phone.. (google it) u will see what I'm talking about.

Thanks for all the replies guys. I tried this to no avail either. I took the battery/sdcard out of the phone and left it for a minute, then held the power button down for 30 seconds or so... then I let that go and pressed and held 1 and power. Then I plugged in the USB cable. Nothing.
Tried plugging it in, then pressing 1 and power. Nothing still.
Phone still refuses to turn on. I'm going to leave it for an hour or two and give it some more time to discharge the capacitors, but I fear it may be bricked (something I thought pretty much impossible for an Epic 4G)

I have read that thread, however it mentions nothing about a phone that will not turn on.

When ur phone doesn't turn on, its bricked. That explains how to unbrick it. If ur phone won't turn on at all no matter what...u may have to take it to sprint for a relacement. That's ur last and final option.

Bricked epic have questions

My epic randomly started acting up last night. So i went to restart it an now it just sits at the samsung screen. I was gonna odin last night but i went to charge it 1st and it comes up to the screen with that battery and locks up there i am not even sure if it charged at it.. any advice? just worried it got no charge and will die during odin.
Just Odin without the battery in. The computer provides the power. With Odin up and the phone off plug in the USB cord and quickly hold the 1 key and power. Should go right into download mode.

No problem. A few people say that is the only way Odin will work on their phone.

Also, you don't even need the battery in to go into DL mode, if you remove battery and plug unit into your computer, it will still boot into DL mode with no battery in it. Good luck!

[Q] I think I bricked and I need help

As the title implies I think I did in my Epic 4g. I flashed the CM7 mtd build a few days ago and just found out about the 911 issue so i tried ODIN'ing back to stock and it was taking forever (it got stuck of factoryrfs.rfs if I remember correctly) so I unplugged the USB cable as I have done before when Odin freezes on me. When I unplugged the battery and then put the battery back in it will not boot or go into download mode. Any advice or did I actually brick it this time? Thanks
I have heard stories of leaving the battery out for a few days might help. Also holding the power button while inserting the battery. I haven't tried those options, but I have seen people mention them on the forums.
I did something similar the other day.
Remove the battery for a couple of minutes. Plug in with no battery and go to dl mode. You will be fine.
Ensure to use the pit file and select repartition when coming from mtd to stock

Advice above is good. Definitely try it with no battery or sd card using the computer as the power source try to put it into download mode. Others have had success popping the battery in and out trying to get into download mode. Hold all the buttons at once while battery is out to clear any capacitive charge.
I thought my phone was bricked thought it would not boot up at all,i after the third day I took it to sprint to get a replacement, I guess the 3rd day was the charm because as soon as the sprint guy put the battery in it booted up to clockwork and they said my phone was rooted and they would not service, good thing I didnt need them after clockwork any way
Thanks for all the quick responses. I left the battery out of the phone all night and tried popping out the battery and plugging the phone directly into my laptop via USB (HP touchpad cable) and still no go. I tried pressing all the buttons as someone suggested to reduce capacitive charge and still nothing, any other tips or am I going to have to visit the big yellow's at Sprint?
Hidden reset button
Ok, I havent tried this... and I also hear that the older epics dont have it. When you take off the back cover, There is a small hole by the camera. I cant find he the xda form maybe someone will be kinda enough and throw the link up.
But some claim that the hole by the camera is a reset button. poke it with a paper clip (gently?) for about 10-30 secs.
I hope this helps, or you get it working some way or another. I'd look into getting a new usb cable if I were you!

Take the battery out for 2 minutes. put it back in. Do not turn it on. Then plug it into the charger for 10 minutes and then power it on. Might sound like joke but I'm dead serious.
**EDIT**
Its possible the things battery just died. If its completely dead it wont do anything I've scared myself like this once as well. If this does not work try download mode. The fact alone its not rooted tells me it might just need some more charging time.

download mode? I dont think so. I'm getting no battery 'vibe', no nothing. I cannot power it up at all.
I only had clockwork installed (no root or rom) and performed a backup then i went to another screen where CW froze, pulled battery and now Its dead. Is there a PC program that i can access the oc from the back side?
I'm figuring that i wiped everything off the phone but if there is a way to access the recovery partition I would like to know!

Install Samsung kies, (this will insure you have the usb drivers)
have your usb connected to your computer but DISCONNECTED from your phone.
Take the battery out, make sure the phone is off.
replace battery, hold down the vol. up and down key at the same time.
while both buttons are pressed plug the usb cable into your computer.
This should get you into download mode, just choose to continue.
From here you can either use odin or kies to flash the complete firmware.

Thanks guys...
Yeah as soon as it happened I slapped myself for not having patience... I'm away on work right now so getting a replacement is not going to happen for a few days.
I'm going to try the warranty angle.
hopefully they don't look to see if its rooted... oie.
apparently there is a company that can JTAG it and basically rewrite to the phone. (hardware needed) I'm mailing it out today.
$80 with express return shipping and unlock.
if this works I will have them do the same for my G2x (apparently I'm good at hard bricking phones <F- I never had a problem before>)
Looks like you had a bad phone to begin with. Never heard of it freezing in cwm before. Just do a warranty exchange. They mail it next day. Then you can mail yours back. No need to do a replacement.
If it doesn't vibrate at all then yeah Hardbrick

ok, so i mailed it to mobiletechvideos.com... paid $20 to express ship it to them, they got it on Friday, fixed it, mailed it out the same day and express shipped it to my house ( i was gone on a trip) and so when i got home, went to my mailbox (today Saturday) and it was sitting there waiting for me.
keep in mind, this was from a solid true brick (would not even power up).
Good stuff!
I had a restore state before i screwed up my phone and guess what, like new (old new) all apps and everything.

Help! Screen broken? Phone dead?

Okay ladies and gentlemen, please take the time to help me out, as I've never had this happen before...
I should state that I am on Slim Bean weekly (4.3) and BionicSheep kernel.
Today I went to the gym, used my bluetooth headset as usual. I turned off my bluetooth when I got home and rebooted my phone (bluetooth won't turn off without a reboot). I laid my phone down (I didn't check to see if it rebooted), took a shower and played video games for about an hour.
When I checked to see if I had any texts, I noticed my phone wouldn't wake (I figured it had a hardboot), so I tried holding down the power button to reboot, which didn't work. I pulled the battery and saw the Bionic Sheep splash screen, then nothing. Tried the power button again, nothing. Now when I pull the battery, I see the Bionic Sheep splash screen about 50% of the time, if that... usually I feel a little vibrate, then see nothing. I have the USB Jig for download mode, which I used and it went into download mode, but then the screen disappeared...
What can this be? Dying phone, breaking screen? HELP!
EDIT: Just tried recovery. I see the blue writing in the upper left that says "Recovery Booting..." then nothing, just a black screen
Then you're not booting download mode, thats recovery trying to boot. Hold home, volume DOWN and power. When it starts to boot/vibrate release power only.
If you can get here flash stock/root66 firmware via odin and report back.

Sorry I meant recovery, not download. Sorry for that. I tried download too as stated earlier.
Do you happen to have the links for odin and stock recovery? If not, i'll take a look in a sec.
EDIT: Just downloaded odin from your sig, I'll check for stock firmware in a sec.
But a new problem, like I said before my phone goes into download, but it only stayed on the screen for a few seconds, then turns off. Odin isn't recognizing the phone at all...
I just tried to do it again, download mode only stays on for about 3 seconds. Odin recognized it for the few seconds its on, then it disappears... any ideas?

So i've ruled out the screen at this point. Even though im 99% sure it was over 75% charged, im letting it sit/charge for a few hours an try again.
Been googling about similar problems... could this be "sudden death syndrome"?

If it powers on without having to press the button, then I am 95% sure that is the problem. The power button is perpetually pressed. It could be the switch is loose or jammed, which I believe is usually the case. It is possible that there could be a short, but I doubt it as this has been happening more and more frequently lately. Some have reported being able to fix it themselves by opening it and either replacing or reseating the button, while others opt to take it to a local shop and have it fixed. (if you do, do not let them attempt to flash anything or they will brick it).
You can try to tap on it to jiggle it unstuck, but if you get it working again, this will certainly only be temporary.

Okay ill give the power button a try before calling the insurance later today. Thanks for your help.
Do you happen know how t mobile insurance works? I'm really low on cash so i'm hoping there isn't a deductible for first time "offenses"...
EDIT: Quick question though, if it was in a constant boot loop with the button pressed, wouldn't I feel it vibrate multiple times and/or see the screen flash multiple times? I only feel/see it do these things once, then its gone.
I just took it apart and the power button was fine, so i'm now guessing this is something more serious...
Well I went through T mobile and am getting my phone replaced for $5. It's on backorder though so I have to wait 5-7 days before they even ship it, which kinda sucks.
Anyways I am hoping they don't see that I flashed a custom ROM. The once in awhile it does show the splash screen, it shows a little sheep on the bottom (due to the Bionic Sheep kernel), and the DL mode that stays on for about 2-3 seconds shows a flash count of 1. I am hoping they don't see it, or don't take the time to check after realizing that it's not functioning properly...
So did you get a warranty replacement then? (Insurance requires a $150 deductible, but it doesn't matter if it's been rooted) If so, they might see that and then charge you, I'm really not sure... I've heard of them doing that and also heard they don't even bother looking.

I called T mobile tech support, and they only charged me $5, not $150. The refurb should be here on Thursday, I guess I'll find out soon enough if they charge me for the rooting (im pretty sure they won't notice since the screen is on for less than 3 seconds, but who knows).
I can always try the 'when in doubt, deny deny deny' technique. Lol

How long have you had the phone? If it's still under warranty then it's just the $5. But in my case where it is a year and a half old and there is physical damage, I seriously doubt they'd go for that!
That also means I might still just get a refurbished T999. Insurance claims go through Asurion, while warranty goes through T-Mobile. And unless I'm mistaken, Asurion has their own stock of refurbs...
