***EDIT for solution***

I really have no idea, and I dont want to pin it to the "magic button" but what I did was
take the battery and sd card out and press the "button" under the battery cover for like a minute. And then hold the power button and 1 both while I plugged in the charger *without battery in* then, bam! Dowload mode!
Oh and before pressing the "magic button" I had tried tis method without it, and it didn't work, but I'm skeptical as to this button so maybe it was just coincidence.

**Edit**
okay so now i odin'd a fresh EC05 install and still no samsung splash screen and i still cant turn it on normally on can get into download mode and turn on with method posted below. does someone think doing a bootloader update with odin will help it? if so can someone provide me the file name required in an odin tar to be able to check the " update bootloader" option?
-----------------------------------------------------------------------------------------
First of all backgroun info, I recently odin'd Stock EC05 selected repartition with the pit and auto reboot nothing else and it passed like normal, then I booted it up, selected debugging, and one click root, now I noticed the once click root took longer than usual this time but It finished and rebooted like normal.
Okay now here's the issue I'm curently running my phone, everything is fine... except for one small thing I can't turn it on! no button combination works when its off the only way I can get it to turn on is by
1st plugging in charger without battery
2nd replacing battery with charger plugged in
3rd waiting until charging screen comes on(and It only comes on with this method)
4th turing it on normally with power button.
and once this is finished it turns on, but I can't get into downlod mode or recovery this way, and what I didn't notice at first boot was that the "samsung" screen at start up didn't show up.
Any help with this would be greatly appreciated as I can't do much right now, and I'm afraid I can't get into download mode.

Sure sounds like a bad flash. Seems like the bootloader is wonky. Since you repartitioned, are you sure you used the right PIT?
For stock EC05 I've always had the best results by using the old official Samsung EB13 installer they had on their website for a while, then letting EC05 download OTA and install itself. Once that is done you can use one click to root.
I know the EB13 tool is around the forum somewhere, just don't know where!
Edit....just realized you said you can't get into download mode. Hmmm...... guess my comments won't help much then. Sorry

Thanks for the input, Hm next time ill keep that in mind then, let's hope there's a next time.
Yeah I don't know how I can get into download mode. I was going to try the acs updater t install a recovery and kernel would that work? Or would it still need acess to a recovery to install them? And yeah I used the right pit, if I didn't id be sitting here with a nice permabricked phone, since I hit repartition.

Any help you guys can offer me?
Is there a way to use odin without going into download mode?
Maybe replace the zImage file written to phone with one click root, with another full recovery?
I can use usb debugging if that's hepfull at all

you shouldn't have to worry about the repartition aspect of Odin until a standard flash won't boot.

OP updated issues still persist can i hit update bootloader on odin? whats reqiured?

[Q] Weirdest BootLoop Ive ever Been In

Ok So Like Im Not Sure What Happend But Ever since i Flashed The Epic Kang Mtd Rom ive been having problems like out of no were it froze so i took out the battery and when i restarted it , When Restarted the Bottom 4 Buttons ,That Usually Turn on once and continue to boot animation, blinks twice and it stays there forever
I Have
-Odin It To Stock
-Used K0anne's method
-Used Samsung Updater
Mos of them didint work and when they did work it was only for a short amount of time so.... Help?
-Forgot to mention that sometimes when im odin'inng it or using the updater it stops in the middle of the process and the screen turns one color

You have a bad cable your screen turning a solid color means its a bad flash/ connection try a blackberry cable and odin back to stock and reroot and flash the cm7 and it should work.

I'm stumped it should have booted did you check repartion when you odin back to stock? If not that could be why its not booting into the bml partition

Are you trying to get back on CM7 or Odin to stock? The MTD conversion takes a couple of boots I heard. I imagine the first converted you to MTD and now the second should flash the ROM. Never did it so just going by what I read.
If you are trying to get back to EC05 with Odin then check repartition and reboot, make sure to use the included Victoryxxx.PIT, take out the battery and sd card, use a good cable and with Odin up plug phone into USB port then quickly put it into download mode. The computer will supply the power. It will not reboot at the end until you put the battery in.

Hi i flashed CM7 to my Samsung epic 4g and tried to flash back to stock... it said error and i just rebooted my phone... i forgot to flash back to CM7 and now it wont go on... it starts up to only where it says Samsung that's it... it goes into download mode and all that but it doesn't show on Odin.... when i try to put into CWM (Volume down + Camera + Power button) it just restarts to the Samsung screen again... i don't know what to do about this.... if anyone had this problem and fixed your phone, please let me know how to fix this. PLEASE!!!

Have you installed the drivers for the phone on your computer?
Sent from my SPH-D700 using xda premium

First of all RELAX! Take a break, go dor a walk, and then comeback to your phone.
Try taking out the battery and the memory card out and leaving bothout of the phone. Plug in your phone, it will look like it's gng to charge, try to go into download mode.
You can also try another USB port. Try another USB cable. Restart your computer.
I had something like thathappen to me the other day, and taking the batt and memory card out worked for me. Good luck my friend. Report back to see if it worked for ya.

Hmmm...out of curiosity, how long do u hold down the vol down+camera+power button? For some reason, when booting into CWM on CM7, if u hold down those 3 buttons for too long, you'll get continous reboots. Hold down the 3 buttons only until the lower 4 buttons on the screen turn on, then let go. Your phone will seem to reboot, but then actually boot into CWM.
This is assuming of course, that your holding down the 3 buttons and its continously rebooting. If this isn't the case, click on the link Kenny posted above n follow instructions. Good luck!

Well I finally got my phone fixed...
I had to constantly change usb ports find the stock dk18.md5 file flash it...
Then root with the superuser.zip file..
And now I'm running viperrom v4.2 and switching between it with superhero v for vendetta rom.
They both work great, but I'm trying to flash syndicate 5.0 but I can't find the file.. its okay tho.
It wasn't me holding down the buttons to long its just that it wouldnt go I accidentally deleted the files to flash into the phone so I had to do all the stress again..
Thanx everyone for the help!

phone shuts down/reboots very often

So I thought I would give up my inexperienced life of flashing and possibly bricking my device(sent it in to get jtag repaired), so I attempted to put it back to stock. I got odin up and running, Downloaded(for the most part) the tar that would make it stock again. about 98% into the flashing it failed and made me a little nervous. I later remembered to flash the kernel, and with it, the phone booted up. Fine and dandy one day yadda yadda yadda.
Now comes day 2, and it just randomly turned off and booted again. it got to the little android boot screen, then shut down again, rinse repeat at different times of the boot process, add in some random shutdowns when I'm at the home screen and using my phone and there you have it.
I figured it was using an unfinished stock rom trying it's best to function, so I tried to put in clockwork mod. I did, but it was very difficult as I navigated through clockwork recovery, the phone would select things on its own, making the rooting process a giant pain. With that monkey on my back, I managed to root and install the juggernaut v.5 rom(which totally rocks) to see if the probably persists. The end result was it still happened, but when it didn't, I was able to work with it normally. At this point in time, I am trying to keep my phone turned on because if for a second the screen shuts off, the phone will start trying to shut itself down and game over. This is still very very annoying and was wondering if you fine people would happen to point someone thats green as grass with this stuff in the right direction

You have definitely earned my thanks for providing such hearty solutions! I am super paranoid now when it comes to downloading files like those. my major concern is if the files never download completely :O I followed what was in that first thread to tooth, and as I installed that md5 towards the end I got a giant fail. regardless, I thank you for the awesome support man:good:

Hmm, try reflashing your recovery. Mount your USB (If you cant, take out your SD card, and mount it on your PC) and place this file on the root of your SD card( Just easier to find this way)

Flash it, and restart recovery. Your recovery should act normal, and do a clean install of whatever ROM you wish. By the way, Juggs was my first DD (daily driver) to!!

From your OP, it sounds like CWM did not flash correctly, you can flash a recovery within a recovery, you just have to restart it or reboot your phone for it to take into effect.

Did you do a clean install? Darkside Superwipe, flash ROM, reboot, wait ten minutes, then reboot?
Sent from AOKP Goodness :-D

Yeah unfortunately it is still randomly rebooting....washing lol

An update to this: all the same symptoms occur, but for some reason when I flashed darkside rom 3 the symptoms occurred less! For example, last night I was able to use this device for 4 hours straight without it acting up. I really wonder what the problem is. I. Mean the thing acts like an angel when in Odin mode, but when it comes. To cwm or anything else it tends to spaz out.

I too have this happening now. I don't know why its been doing it. I was running the latest aokp and than it started rebooting and shutting off. So I went back to my nandroid backup and still continues. Running darkside v7, and problem is still there. Anyone know why this is happening?
It started happening while listening to music.

Here's a logcat, I used catlog right before it shut down. I cannot comprehend what it is trying to say, hopefully one of you can help me out. Thank you.

That's exactly what I was thinking. Everytime I would lock my phone with the power button it'll turn off and stay black vibrating. When I lock my phone using screen off and lock app it won't turn off but to unlock it I have to use the power button, than it turns off.

In the non touch clockwork recovery use menu to scroll down. Home to scroll up. Back to go back. And search to select. I figured it out by my power button clicking things.

the only way i know how is through odin. I've done it a few times. at the end of the flashing I find that the phone turns itself off or something which marks it down in odin as a FAIL..when in actuality it flashed....it just needs a kernel flash and it'll all be candysticks and lollipops.
At this point in my phones life though, however, it is increasingly harder to do anything in clockwork since the button is fudged up. I think I might have to pony up 35$, but if you can Odin your phone back to flash and tell T-Mobile/Samsung about it, you can probably get the repair for free

[Q] Think I bricked...

Bleh just got my Optimus yesterday, came stock with zv9. Decided to root today and had no trouble, flashed TWRP recovery using FreeGee then updated to the newest TWRP version using GooManager. Made a backup using TWRP then used GooManager to download Lifeless ROM. Just downloaded, didn't flash. After the download was done I shut off my Optimus but when I went to restart it, it powered on, showed the LG logo for half a second then just went to a black screen. Can't boot to recovery. Whenever I try and turn the phone off it just restarts again showing the logo for brief period of time then black. Any ideas? It's gotta be bricked but I just don't understand how or why. Probably going to try and take the battery out and see what happens.

Probably going to try and take the battery out and see what happens.

okay well your not bricked if you can get even a little life like an LG screen. hook phone up to computer and use adb to get into bootloader and try to reflash the recovery img again. it just sounds like you need to reflash your recovery. thats why it didnt flash. lemme know. ill keep checking back on the thread for awhile

Okay perfect I appreciate it. Downloading SDK right now, I'm away from my desktop and didn't have it on my lappy. LG has a program similar to ODIN too right? Would that maybe work as well?

You would need LGNPST. you can find it in the IRC if you can get to download mode you can flash back to stock and start over.

Yeah that's it thanks. But forgot- can't get in to download mode so that won't work.

I ran the command "adb devices" and the Optimus didn't show up. Is there anything else I can do/try?

Just because the screen doesn't come on don't think the phone is off. Plug that sucker in. If you see the logo you should be able to get in download mode. Also, if the phone is on, you will eventually see some green android screen.
The same thing happened to my phone once. I only know of one way to hard brick this phone. I am not telling anyone how. But, I doubt you did that. It isn't something you would accidentally do.

It's on but it just shows a flat black screen. No matter how long it is on it doesn't get passed that. Also, when it's plugged in there aren't any charging lights. Not sure what to do since adb doesn't recognize it.

Holy boobs volume up and plugging in worked. You are an angel much thanks.

I had the same situation a month or two ago. Try leaving it off for 20 minutes and see if it boots back up. Worked for me and like you I had no idea why it did that

i did this this past weekend. Dumb mistake, i forot that it wiped the unlocked and there isnt unlocking yet for JB.
After using LGNPST my radios/3g/network connection is screwed up. I cant connect to anything.

Update your profile.
If that doesn't work LGNPST again. Factory reset. Then update the profile.

If what kc doesn't end up working it could be that you efs got wiped. Check this thread for help http://forum.xda-developers.com/showthread.php?t=2161498

These are what I tried:
factory wipe/data reset from stock recovery
MSL reset (suggested by Sprint)
lgnpst reset
All of which failed to work

You are going to have to pull the battery.
