samsung epic - Epic 4G General

my samsung epic wont boot up it just stays at the samsung screen

What was the last thing you did before this happened. Are you able to boot into recovery by holding power+camera+and volume down at the same time.

Worst case search for restore brick in the dev forum. As long as you can hold 1 and press power to get into download mode you'll be ok.

What's the safest method to root Vibrant and load a Custom ROM ?

So, I'm getting the Vibrant soon. All these different methods have me confused. So I'm looking for the safest and simplest method to root and load a custom ROM.
All the methods are pretty simple if you took the time to actually research the steps. There's a "bible" of everything you need to know stickied in the general section.

before you do anything, check to see if your vibrant can boot into recovery. hold volume up +down while you turn it on. if it goes into recovery mode, good. now try download mode. turn it off, plug it into your computer and hold power , volume up and volume down. let go of ONLY the power button when the screen turns black (switching between the charging icon and the bootup screen) and continue to hold vol up/dwn. if you see a yellow android with a shovel, you're good. if not, that means you have a hardware locked vibrant, so if you soft brick (not that hard to do) your screwed. (you can take it to tmobile and they will replace it for you. this has been acknowledged as a defect in some phones)
if you aren't hardware locked, feel free to root.

Tip for getting into Recovery Mode:

On my Verizon LTE it always seemed to blow past the screen were you select recovery or download mode. I found that if as soon as the "Samsung 10.1" text shows up, if I quickly release power button works. This may be one of those "DUH" Posts but I never caught on that I could release the power and keep holding the volume and it would continue to the boot menu.
This isn't such a "duh" post - I found it quite helpful. Thanks
I thought it was just me who couldn't get it to work right. This tip got me to the screen instead of blowing straight to the download screen.
Thanks

[Q] Bricked D800 after flashing 'boot animation'

Well, I finally bricked my first phone since starting with the Dream way back when.
I was flashing different boot animations on this D800 and came across one supposedly for T-Mobile. I had unlocked the phone, and changed from AT&T to TMO, so I thought it'd be appropriate. Boy was I wrong.
As soon as TWRP flashed that ZIP and rebooted, the screen went black. No LG logo. No animation, no sound, no nothing. So I looked into the ZIP file I downloaded (from somewhere on XDA, I'll have to find the thread) and it looks like a full TMO ROM. Great!
Now I can't even turn off the phone. I can see the backlight on the (black) screen, and when I press and hold power, it restarts after 10 seconds, but then comes back on. Something else strange is that a drive F: shows up on my PC, with about 70 MB of various files. Then there are about 10 other volumes, G: through T:, but they are empty.
Now what?

Have you tried to get into recovery using power+down? If so, how about download mode?

Yeah, I had just made a backup in TWRP, so my first thought was get back into recovery. However, Power+Vol Down doesn't do anything except reboot, just as it does when holding only the power button. Same thing with Power+Vol Up and holding all 3 buttons down.

You need to keep holding until the LG Logo comes back, then release and hold the buttons again :good:

Yeah, I have tried holding them down for multiple reboots but it's all black, every time. I haven't seen the LG logo come back up since I flashed that ROM. I've tried letting up on the Power+Vol Down button at various times to try to trigger it and I can't figure any way to get into recovery.
try this solution. It may help:

I assume you've tried shutting down completely first?
The multiple drives is good, you can resolve this. In not near my computer now but try looking for a thread about no recovery no download mode etc, in that thread it is suggested to connect phone with usb while running ubuntu.
I used that thread to revive my phone after a bad flash.
Keep in mind that the files mentioned there are maybe not for your model so you will have to find the correct files.

When I get a black screen after flashing a boot animation and the phone does not boot (just gives a black screen) I usually remove the boot animation via adb. This will use the generic Android boot animation and boot your phone up

Well, I don't think this was a boot animation, even though it was advertised as such. I wasn't thinking, because I know better than to accept a 798MB file as being just animation, no matter how elaborate. I mean, I've been doing this since 2008, but I flashed it anyway. Only after it blew up in my face did I look inside the ZIP and see all the stuff you'd have for a full-blown ROM. Ugh.
In any event, I don't have any adb shell or devices or anything when it boots, just those weird drives.
The real kicker is. this is my 2nd G2 -- the first one having gone into some kind of CPU thermal runaway. I had to send it to Samsung in TX and they replaced the system board. So I've "used" this phone, which I first bought December 5th, for only about 3 weeks total at this point.

I eventually figured out that I can get it to turn it off, by continuing to hold the power button, At first it will reboot, but after a few more seconds it turns it off. Or what looks like off -- nothing is ever drawn on the screen at this point, not even the LG logo. So I basically have to hold the phone up to my eye and watch for the backlight to be on or off.
I also left it "off" overnight, but it didn't help.

I just read your post saying that you had flashed an entire ROM. Do you have a ROM backup you can restore?
D803 up in this *****
Have you tried while it's powered off to turn it on and plugging in the usb cable(connected to pc of course) to see if it enters download mode(just incase I myself have never been able to access download mode using the button combination on the g2), if it enters download mode all you would need is the LG flash tool and a tot of the d800 to get back to stock?

Yeah, I was going to mention this. Once you have it completely powered down, hold volume up and plug it into your pc. That should throw you into download mode where you can restore through lg flashtool.
Alternatively, while powered down completely, you can attempt to boot into recovery by pressing and holding volume down and power, hopefully the lg logo will appear again, and you can release and press both again. I've been in situations where it took me a bit, meaning multiple tries and a few dirty pairs of underwear, to get it to work. But it eventually did. Admittedly, none of these instances occurred after flashing a rom for a different device, so your mileage may vary.

Bootlooping? At&t H910

I think my v20 has started bootlooping. I am not 100% sure exactly what bootlooping entails but I plugged in my phone last night with my normal charger and when I woke up the phone was stuck on the ATT logo splash screen. I tried to hard reset but holding the power button didn't do anything. I have to take out the battery to power it down. Now every time I try to power up the phone either gets stuck on the LG or ATT splash screen. I spoke with people from ATT and they said I could send in my phone as it is under warranty but they're is some data I would like to get off of it first. Does anyone know if there is a way to even temporarily get the phone booted?
Turn the phone completely off. Hold the volume down button and power button at same time. As soon as you see the LG screen, let go of the power button still holding volume down but Quickly re-press and hold power button down all while still holding that volume down button. Can you get anywhere like that?
Oh yes, I got to the factory reset screen. Thank you for some progress. Would the only option from this point to actually reset? Most of my concern with doing this myself was to recover some data.
A corrupted sdcard can do this try turning the phone on without it

[stuck]help needed asap

I ran into a situation where I got my phone reset and it got into a bootloop. No probs I thought but I realized the long press power button doesn't work and I'm LITERALLY STUCK in bootloop. Phone is hot like hell.Need some tips ASAP.
Little bit of history:
Running alexis 3.0 rom with nx kernel,xposed with xposed edge,bixby remapped
Went down to 0 charge,put my phone to charge and turned it on
Buttons just wasn't working,neither power/volumes/bixby.Nothing
I rebooted to recovery with app,power button worked there so I supposed no big probs
The stupid idea came to format data,cache in twrp and check if the buttons work after that
That's when it got stuck and now I'm sitting here desperately trying to do something but power button just not working,phone's hot,trying to cool it off
The battery went up for 4% so my last ultimate hope is to discharge in the near future,hopefully asap

I have had this issue on my s8 where it got stuck in bootloop/samsung logo and holdimg the power button did nothing.
Holding the power button and volume down button for a few seconds or until it reboots seems to force reboot on my phone . From there you can let it start normally or go into recovery/download mode.
Hopefully this might work on your phone.

Thanks mate! I've just figured it out yesterday and phone is good now. Seems like the three-button combination is the always-working hard reboot.
