I would recommend taking it to the service because i think you have a damaged eMMC board, further trying may result in a hard brick thus you can't recover your data.

I can access Download Mode, and Recovery, connect to PC and transfer my files to Internal and External storage, but I cant boot on system. My problem is on eMMC? My battery is made in 2015, I will change as soon as possible. Now I'm trying to do a full wipe, include sdcard, and re-installing Fulmics.
Edit:
The phone is back! But lost all my apps

After applying a 6.5 ROM and trying to revert back (with SPB Backup file) to 6.1 the phone went dead
I mean totally black with no lights - nothing, cannot be turned on.
I recharged the battery, tried all sync cables ... but without success
Is it garbage time? or...can be saved somehow?
You can't revert back to wm6.1 using a backup. You need to flash a wm6.1 rom.

I cannot turn the device on, therefore cannot flash it
Oh. Maybe there's an emergency mode for your device. Is it an i780? I' ve never heard about u780 so i think you pressed the wrong button.

oh...thanks, I edited the title
Emergnecy mode for Hard reset, etc? This is not relevant since no power is even shown on the device
when I press the "power" button the led doesn't light
Hardreset-->Turn on the phone keeping pressed green and red button (it should work)
If hardreset doesn't work reflash but instead of normally turning the phone on, turn on the phone keeping pressed enter and fn (black and white) buttons
sorry m8....i had a similar issue. my i780 went dead...and i had to turn it back to the service center. they told my mother board had fried....and i had to wait a week for a replacement. the support guys wont know you've flashed a new rom...just stay quiet and u'll get another mobo.
what is it that you last did? here are the possible things which triggered this for ME -
1. i'd left my i780 in the sun for 4-5 hrs (in my car dash)...and it was burning hot....so this might have fried something....but it worked fine till that evening before it bricked
2. the same day (after i'd left it in the car)....by evening, i turned my wifi on and left it that way for 4 hrs or so....so over abuse of wifi might have bricked mine?
3. i'd flashed wm6.5, then heroes 6.1 rom.....so was it the flashing around?
4. maybe just samsung has some hw issues with the i780...
bad luck dude!

I don;t think the MB fried...I did #3
I just cant believe that it totaly bricked it, I mean I would have assumed that I can evie it from any stage - but this is like I am holdnig a brick and no more
Someone suggested to open up the back cover and clean the battery terminal - will try this as well
Service Center is not an option - I bought it in Thailand

i took it over to service....at service, the representative opens it up right in front of you and checks if its a minor fixable problem - then and there. So the service rep tried all possible stuff and couldnt manage to get it working. So, eventually they had to send it to higher level service, which took another 4-5 days...and finally they reported a dead mobo which was then replaced under standard warranty.
this sucks dude....i think you're having the same problem with your device that i had. You need to try your luck with service and hope that they give you a free replacement...i think they have worldwide warranty, you could tell them you lost your bill/blah...best bet if you ask me. Or paid service i'm guessing...
sorry m8....this is starting to worry me on the quality of samsung's hw....hmm (never had a single problem like this on any of my htc devices)

after i try to update my win 6.1 orange rom pbvic2, the mirage got stuck at 13% and after that my phone won`t boot, get stuck at first logo, i try another roms but without success, plssssss help me
Hi guys,
I have HTC One X and I switched from stock rom to cyanogenmod few months ago. From time to time I got info about updating to latest stable build but I didnt install it since the one I had worked perfectly. Few days ago I updated it to latest stable build manually and it worked OK, but it shut down at one point when I was using Google Maps and I had to start it manually again. It started normally but had problem connecting to network for about minute or two. After that it worked fine.
Today I wanted to record my sisters school project and I put it on a table and started recording. After 20 minutes or so I noticed that phone is turned off again (no one was near it). Since then I am unable to charge it, power it, it seems to be complity dead. When I plug in the charger no light indicartor is present.
I am not sure that problem is OS related. It seems to be hardware related isssue.
Is this known problem? And how to fix it??

Brand New Device, Its just been a Week...
I Rooted and Installed CM 11 Yesterday.... So Today,After watching some Anime Video's on it..I Left it for almost 1 Hour... Came back and tried to unlock it...Touch wasnt Responding well.And Phone's Screen was hot indeed.. So Even Shut down wasnt possible ...
So i used Power Button for 10 Seconds and Restarted... Phone Restarted...But again Phone was very Laggy,So Tried Restarting again...This time.... No Display nor any Touch Buttons were lighting up... Instead what i got were random Vibrations.... I tried to get into Download Mode,Recovery....... Yet no Response from Screen but only a Vibration from Device itself...
Any one faced this issue? Any Known Solution...? I wont get free Warranty as Device is from UK

I had these screen issues too... But for me removing the battery and reflash the Rom did it...
Seems like your new phone has over heated and caused some serious damage to screen and maybe gpu\cpu.
Seen this happen recently with a ROM I installed also. But pulled battery out in time. And installed another.
I always watch out for over heating when installing a new ROM. Usually a sign somebody messing with CPU clocks.
For your sake though I hope you got it in time and can flash another ROM.

I dont think its ROM issue...But Right part of Touch not working... and display gone off... Works without screen... And whenever i give a blow on that right side of the screen....Display Flashes and goes off... I have given it to be checked in a local store
UPDATE : At a Local Shop,they said display is damaged because of water ... [ i never kept or used it with water]
Samsung Store said ...Display was burnt from inside and they will replace it for 6k Indian Rs.... :crying: :crying:

Hey I've seen this issue too, one of my friends has a GT I9192 and I updated his phone to the latest stock ROM first it worked very good, but one day he was recording something with his camera, and then played the recording after that the phone shut down, and didn't want to restart after taking the battery out and trying again and again, it reboots and after 3 or 4 min turns off again. I flashed some other stock roms but nothing, when I get in recovery mode, after some minutes the screen goes all blue.
And sometimes when restarting it shows colored lines in screen.
Went to Samsung Costumer Care (Saudi Arabia) they say that the phone has been rooted (which is not true) cause the KNOX Warranty bit shows 0x1
I don't know what to do.
The phone was bought in Saudi Arabia. And I live in Europe
Could I send it somewhere in Samsung CS in Europe cause i heard that here in Europe the KNOX warranty bit doesn't affect hardware damages (which I think that this issue is a hardware damage)

Well i have had a similar issue with my T2 Ultra....Not exactly the same but when i used to plug the USB in...phone wont charge while its turned on......and when i wud switch it off it wud show me discharging status........What i have figured out in my case were 2 things... Most likely it has to be the USB driver cuz it happened to me twice and both the times my laptop was going through an Update.......after finishing the update and restarting the laptop....everything went smooth. Secondly i googled about this issue and i read somewhere that its cause cuz of the USB pin (inside the USB slot in the phone) bends slightly down so cant connect properly...so i moved it to the center with the help of a flat headed screwdriver. I am not sure it would work for you but its worth giving a shot.
