Bricked my phone. What do?

So I was playing around with different kernels and whatnot but it froze while I was flashing back to stock. I pulled the battery and tried to reboot the phone but only the blue LED came out. Anyone know how to solve this issue or am I screwed?
I tried getting back into download mode but only the blue LED notification light turns on.

As a last resort try a USB jig. I wouldn't mod a Samsung without one.

There are several OG Epic tricks you can try. Try removing battery and SD card and plug phone in to PC and see if it powers to download mode.

I was building something and screwed up my phone. I had to send mine in for firmware repair. I'm no noob so I tried EVERYTHING.
Either take it back to sprint and play dumb or get it fixed from the guys at mobiletechvideos.com

You can try saying you got some random message that an OTA update showed on your phone and you accepted it and it screwed your phone up. Just a thought coming out of left field

I had the EXACT some problem last week. I went to the repair center, said the phone was plugged in at work, we had a power surge, and afterwords the phone wouldn't turn on. An hour later...BOOM, new phone
I then went on amazon and purchased a usb jig and kept my phone stock until it came. lol

Every rooted owner should spend the 2 bucks on a USB jig. It's not the holy grail, but it's one more tool in your belt to potentially get out of a frustrating and time consuming situation.
I bought mine from here and got it pretty quickly considering where it came from ...

I agree. I spent a little more on mine because I wanted it asap but we should all have one of these just in case.

It will potentially force your phone into download mode from an "off" state when you otherwise can't so you can connect to Odin and get your phone's system restored.

Also try this of epic trick. Sounds funny but worked. Pull the battery and sdcard and let it sit for at least an hour. Put back together and try download mode.

I forgot to mention letting it sit when I mentioned this to someone else (or was it here?) about pulling battery and SD card. Also repeatedly press or hold power button with those out to purge any remaining juice in the phone. This stuff sounds crazy but ask any former OG Epic owner.. some of these tricks have brought phones back from the dead. There isn't a pinhole under the battery cover below the camera is there?
That last part was an OG Epic inside joke but the rest is worth trying

Problem with phone charging.

My phone has been continuing to say that its charging after I unplug it. I've tried a new battery a new charger and wiping my battery stats. Has anyone else encountered this or know a fix?
Sent from my SPH-D710 using xda premium

If it were me, I'd Odin one click back to el29 stock rooted and see if it still happens.

Before doing anything, did you try to 'fix the permission' from the recovery and see it's still showing charging?

I don't think my computer or the phone recognizes the connection between the two for me to odin . Ill try fixing the permissions now and let you know if that works.
Sent from my SPH-D710 using xda premium

mobile odin is your friend whenever the computer refuses to acknowledge your phone's presence.

OK fixing permissions didn't fix it so I guess the next step is to Odin a stock rom. Can I use mobile Odin to flash a full stock unrooted rom?

Any help please? Can someone help me with flashing a stock unrooted rom with mobile Odin.
Sent from my SPH-D710 using xda premium

I had this exact problem last week. Just one day it continued to tell me that it was still charging even though it was unplugged. Also, it would randomly say "USB Connected" throughout the day. I think it may have been caused by the fact that I started using the Kindle Fire charger to charge it (it just happened to be conveniently by my bed). The Fire charger is much larger and I'm guessing higher voltage.
But I tried restoring to stock, jiggling/cleaning the usb port, and every other thing I could find on the internet, but none of that worked. I just took it in to Sprint, a technician confirmed the problem, and ordered me a new phone. Painless.
But I do have TEP... If you don't, I heard that instead of just swapping out your phone, they'll order another USB port and just swap that out instead.

Why don't you just mobile odin EL29 stock rooted? If your phone won't charge, you could get an external charger and charge batteries outside the phone. You could just rotate the batteries and always have a backup. There should be a link to the unrooted tar for EL29 in the one click odin EL29 post. Just follow the directions. No need to hold your hand, it will work, just read first then follow the directions.

You have corrosion in your charging port. Take your battery out, get a nice stiff-bristle paintbrush or a tooth brush, scrub your port out really well with alcohol. Make sure you dry it thoroughly before powering back up.

[Q] Help? I Think I Just Bricked My Phone

I was in odin attempting to go back to stock and my screen went completely green during the process, left it plugged in hoping it would just keep working, but odin stopped. I am pretty sure my battery died during the process (very dumb of my but I was paying little attention to battery beforehand). I eventually pulled the battery, and now I cannot get any response from my phone at all. Won't charge, won't go back to odin. Any suggestions?

Battery CPR. Pop it in and out and try to get back into download mode. The colored screen is a sign of a bad cable. Get a heavy duty blackberry cable. You can also try with no battery and the usb cable in the computer to get into download mode. It will go in eventually.

I finally got it in Odin battery-less after about 50 unplug/plug back ins. Popped battery in during that process and got a successful reboot and now charging. THANKS a ton for the fast help. You're the man!

I bought 3 of these for different locations. (Work/Home/Laptop bag)

Interestingly enough, it seems to be a combination of cheap cables vs. usb ports. My laptop can Odin first time, every time with the stock Samsung cable. However, my work computer fails 19/20 times unless I use the smaller stockier Blackberry cable I have.

Is your work computer a desktop? And if so are you using the USB ports in the rear directly on the motherboard?

It's a desktop, and I've tried all 6 ports, 4 in the back, 2 in the front. Same results all around. Of course, this computer is a relative beast, but it seems to have usb issues regardless.
On the other hand, my home desktop has no issues as well, I just don't use it as much as my laptop. Develop alone in a dark room? Nah! I develop on the couch watching Big Bang Theory with my wife and son.

Well Im desperately trying to find anyway to avoid jtag expenses, i took.it to a sprint tech i know who deals with this stuff after i had exhausted my options .He said jtag it . Earlier today i made a 300kohm 1/2 watt jig but to no luck it wouldnt force dload mode?
Ive been reading on this other explored method of sd card unbricking using a jig and tweezers to trip a resistor on the board and manually flash a new bootloader it seems..very very very complicated
And noone has succesfully done this as far as i know.
All i did was accidentally flash my old gsm note 2 t889 backup ,jedi master10 rom, when i meant to flash jedi invasion I overlooked the words master for invasion after it flashed it said
Install failed in RED and No OS installed at top then i realized what i did and tried to Save my a** and restore my nandroid that failed also ,then i tried to dig myself out this mess and flash the only other t999 zip rom i had on my sd and that failed Said no OS Installed on top after i rebooted never could reboot again Not even 3button.works for dload mode

I believe you are correct. I am still a noob at this tho.. But from what I see from an engineering stand-point, you nailed it.

I don't know all the specifics in your case, but I can tell you this about a hard or a soft bricked phone.
Plugging a Jig into any android phone is safe and will not harm it at all regardless of it's condition.
If the phone is hard bricked it will not go into download mode even with a Jig.
It makes no difference what the issue or problem is with the phone, simply
plugging a Jig into it will either get you into download mode or it won't.
The way you can tell if the phone is hard bricked is if the phone's screen and or
led's do not light up at all even with a known charged battery and regardless
of which button or combination of buttons are depressed.
If the phone vibrates it usually means that it's not hard bricked.
Hard bricked phones are DEAD they show no signs of life at all
that's why they are called BRICKS.
One of the nice things about the jig is that it can work even if the computer
does not recognize the phone when it's normally plugged into the usb port.
So if your phone is NOT hard bricked my suggestion would be to plug in the
Jig get it into download mode and have Odin ready with the stock or stock
rooted Tmobile Jellybean v4.1.1 firmware ready to flash using the TAR file.
Good Luck!

Is this a paper weight?

I got a sgs4 and was selling my s3 on craigslist. And was puting it back to stock. Well my son decided to unplug the usb as it was odining.
Well now, it wont go into download, recovery, wont turn on, and wont even show an led while plugged into charger.
Im guessing this phone is hardbricked. But is there any way of fixing it?
Iv heard of the jtags, but have never known how they worked or what they do.
Can my phone be fixed at all? Or is it done for?
Thanks in advanced if anyone is able to help

Sure sounds like a paperweight..
Go to mobiletechvideos.com and read up on how to use their Jtag service. It's very easy and they are very reliable.
Before doing so I suggest double checking that the phone is indeed hard bricked.
1) Remove the battery, reinsert it, and try entering recovery or download mode once more
2) plug the pbone into the pc and see if you can see a red led light. If so try entering download mode from that point on. If ODIN can recognize the phone try flashing back to stock even though you may not see anything on the phone.
