[Q] My phone is dead..... help

So I did a Root 101 No No... In a sleepy state I decided to flash my T-Mo galaxy S2 without doing a system wipe..... smh...smh. As a result I brick my phone. However, in a way I've never seen before. Is there anyone out there that can help???
Here the problem:
Phone does not turn on. (No sound, nothing on the screen)
Phone does not respond to 3 button press. (No vibrate and can't get into clockwork)
Phone does not connect to usb port. (it contently connects and disconnect)
As you can see this is a BIG problem and its left me stump. Before I declare this phone as a shiny paper weight I leave my hope in you guys.
Thanks for the help

What is the three button press? To get into recovery I hold power and volume down. Also check if you're in a boot loop
Edit: also what ROM did you flash

I meant the volume and power buttons. I don't think I'm in a loop because the phone give me no type of feedback. no light, sounds or vibration. When connected to power outlet there's no change. took out the battery for about an hour, no change. used a different usb cable, tried to load into Odin. Nothing.
The only thing the phone does to show that something is going on is when I plug it into my pc. At that point it shows a device has been connected but then disconnect right away. It keeps doing that as long as the phone is connected to the pc.
Also I was coming from CM 10.0.0 to aokp_d2tmo_jb-mr1_build-4

Probsbly you are trying to get in recovery mode in proper way, just to confirm, first you have to press vol low and up button, keep holding it and then press power button. few sec later it will vibrate, release power button but keep holding vol up/down. Samsung logo will come and then it'll enter in recovery mode.
Just wanted to make sure as sometime people get hard time to get screen shot by pressing keys.

[q] at&t s3 dead

I was rooted with CM10.1.0 and was casually using the phone until it randomly turned off. I turned it back on and the only thing that happened was the "Galaxy SIII" screen flashed and turned off again. I popped out the battery multiple times to be welcomed with the same problem again. I can't boot into Download or Recovery at all. Anyone know how to fix this? (btw im on AT&T SGH-i747)

Try another battery.

Please don't provide false or miss leading information.
To OP. Fully charge your battery or use another one if its corrupt.
Try booting up into both recovery or download mode using the proper combination.
Use this guide to get your phone fully working again.

In some instance (very rare) your phones hardware can malfunction, but seeing how it still boots up I doubt its that's.
Follow my guide and you should be fine.

As long as a phone is able to boot up its fine.
Like I said please do a little more reading and research and don't spread false information.

What about with it plugged into the charger and try to get to download mode. I thought I bricked my s2, took the battery out but it stayed on. Thought it was possesd bit it was plugged in to USB.

Can't hurt to try.

Definitely recommend download mode with cable plugged in to computer. Are you sure recovery doesn't work while plugged in to power?

Yep. It just loops on the splash screen. I'll try charging it to full and repeating your solutions. (It died off at 80%, very strange). Thanks for your replies though!

Ok guys, seems that my issue isnt the phone being bricked. I left the battery out all night and popped it in the next morning. CM loaded just fine. However after about 10 seconds of it loading, the power menu flashed, i clicked cancel, and then it immediately shut down again, and the usual problem continued. Any thoughts? (btw the phone died at 80% battery the first shut down it had, right now it should have been nearly 100% after charging) Also, connecting it via USB doesn't help at all. Sometimes the blue recovery words flash when i try to boot into recovery, but nothing happens after that.

It could be a bad battery. Might also be the battery contact points. Worse case is something is wrong with power channels on the Mobo. If it is the last then you will have to warranty the phone if you're still covered. I would borrow a battery first to rule out whether or not it is the battery itself.

The power button seems to operate normally, but that could also be one of the things that are causing problems. Once i find someone nearby with an S3 battery i'll see if it's actually a battery problem (most likely the case).

I'd thought i'd mention this as well, whenever i pop in the battery, the phone vibrates and tries to turn on, but doesnt actually do it. Anyone have any ideas what could be causing this? power button maybe, but battery?

If the battery out all night boots past the splash screen maybe you could, if you haven't, leaving it out and first thing try download mode. I've been in bad spots but this pretty crappy. Probably to technical for me but Good luck. Let us know how you do if none of the posts help.

Found the problem. The power button is always acting as if it's being pushed down when it actually isnt. The phone starts up perfectly when i hold the phone horizontally with the power button facing down. then when i put it back into portrait mode, the power menu flashes, and its turns off. any knowledge on how to fix this then?

Um I'd say taking apart the phone or mailing back for warranty even try taking it to an att store.. Its hardware and not software so they should replace it

[Q] dead phone after Jiedi Master 16 ROM flash

Hi All,
I tried to flash Jedi Master 16 ROM http://forum.xda-developers.com/show....php?t=1958230 to my ATT unlocked E980 LGGP for T-Mobile. Now the phone is dead, i.e. not responding to anything. Please please help.
Rooting and installing recovering image, Optimus G Pro How to get ClockworkMod CWM and make a backup | LG Optimus Forums - Android Optimus Forums
were successful. Flashed the stock Jedi Master 16 ROM (no change to the zip) all seemed fine till the installer prompt me to reboot with successful installation message displayed. After confirming rebooting, the phone is no longer responsive. Battery is fully charged before I left it alone over night (~6hrs). Battery still had full voltage in the morning. Battery pulled/reinserted a couple times, volume down+home+power pressed many times. Phone still does not respond at all. Connected to the computer, and the computer said the device driver installation failed.
Searched everywhere and found mentioned "deep sleep" symptom. However, battery was not drained. The so called "bricked" seems to referring to looping in booting. Mine is simple not responding to anything at all with or without battery in, with or without wall charger connected, no matter what key/keys pressed.
I suspect that I should have put the right modem file into the Jedi Master 16 zip file.
Please help and thank you in advance.

I'm not even sure what to say.. Why the hell would you install a Samsung Note 2 ROM on your E980???
Can you at least get into recovery mode?
Pull battery then put back in
Hold vol-up+power+home until it passes the lg logo and goes black then release.
Are you in clockworkmod recovery?

My bad. Thought Jedi X is Note 2 specific and Jedi Master is somewhat generic.
Phone won't even boot. Screen is off, and no LED lights/sign of life anywhere with the battery trick and vol-up/down + power + home trick.
When the battery pulled and USB powered, the back and menu led flashed (white) once. Then no more sign of life no matter what key(s) + power buttons combo press.

The only forum you flash roms out of is this one and it must be for the E980. Your only hope is to try and flash back to stock
http://forum.xda-developers.com/showthread.php?t=2302660
if that works and you're back on stock then root and after that you have to use FreeGee to install a loki recovery..i suggest the cwm one. just make sure to select unlock security etc
good luck

I understand what I should do after the phone boots up. Thank a lot for the resources.
However, I am stuck with how to make the phone boot. Is there a hardware reset button?
Methods tried so far:
1. Pull and reinsert battery, then press power button.
2. Pull and reinsert battery, then press (vol-up/down) + (camera shutter) + (home) + (power button).
3. Left the phone alone for 6hr (no USB charging). Battery is at full voltage (4.12v). Then following step 1 or 2.

Dude you need to simply do this. Pull battery, put battery back in, hook to computer and while plugging in the cable to your phone, hold volume up and down. If you see the 'download mode' box in the middle of the screen, YOURE SAVED, IF NOT THEN YOURE ****ED!
Never flash anything unless you know what you're doing. I seriously advise you to do a serious amount of reading before ampting any flashing if anything!

Points are well taken! I was in a rush which I definitely did not have to.
Tried the vol-up+down combo tip. No response. I guess I need to resort to some JTAG repair.
Thanks a lot.

I dont think there is such thing as a Jtag repair for this phone, if there is no one knows yet.

Methinks the former. The OP took a "parts is parts" approach to Android and made an expensive mistake.

Unbricked
My phone is finally unbricked using JTAG thanks to this man!

Everything is bright and shine except the partition table is screwed up where all apps (like camera app) see there is no space in the internal sd card. Waiting on the external micro sd card to arrive. Hopefully that will make the phone usable (beyond just browsing and installing apps).
In this stage, I can't even root it since the rooter can't write onto the internal memory space. And Android Partition Manager Pro, who requires the phone to be rooted at first, won't help either.
Does any one know how to repartition without rooting? Thanks a lot.

Screen always on

Alright, so here's the deal:
After much searching, and a few new grey hairs, I've arrived at the point where I feel a new thread is justified. Recently, after a SlimKat flash, my screen lost the ability to turn off, and stay off. Typically, invoking a lock screen and having the appropriate timeouts set will allow the screen to sleep, but my phone is no longer behaving this way.
When I lock the screen, or the screen locks based on settings, instead of it staying off until I press the power button, it continually comes back on, displays the lockscreen, then turns off...then back on again...repeat ad-nauseam.
Please help before I launch this SOB off of a bridge.

Once done, I'm going to verify lockscreen operation, then probably flash away once again. This was an odd issue, to be sure. Never seen anything quite like it over numerous phones/roms/years.

Somewhat of an issue...can't boot to Download to get root; can't run rebooter app without root to get to download mode. LOL
Plugging away, but lockscreen appears to work with OEM ROM.

No I mean if it reboots as well after 10-25 minutes in recovery or download mode like it does when booted normally. That would confirm that its likely a power button issue

Are you using GT-I9500? If so this is the wrong forum.. But what I would do is backup all my personal files, important messages etc. flash stock firmware with Odin, reboot to recovery and factory reset.
