[Q] Trouble while updating the ROM and doesnt boot anymore - Galaxy S III Q&A, Help & Troubleshooting

Hello Guys,
I have a Galaxy S3 and 2 days ago I have installed the latest version of Cyanogenmod using Odin but it was not working properly. So I decided to install the Samsung ROM again (V.4.3). While I was installing it, USB disconnected accidentally. I tried again and instaled it. However my phone cannot boot anymore. Samsung logo appears and keep staying on the screen till you disconnect the battery. Then I tried to install the stock 4.1.2 ROM but its the same. I think I am in a big trouble. Can anyone help me?
Thank you.

Soft briked or hard briked

Hi all.
I have already posted my problem in this thread which I have read to the end ( [GUIDE] Fix an unflashable or soft bricked I9100G )
but was not able to get any solution so I'm starting a new thread hopefully someone might be able to help me and sorry if I was not suppose to start a new thread.
My problem is as follows and hope that someone can help.
I have downloaded odin mobile and installed it on my S2 I9100 G which previously had CM 10 installed on it and I wanted to flash the official firmware using Odin mobile. I did run it and then the phone prompted me for M5 or Md5 that was detected and should click yes to verify before flashing. I clicked yes then it started verifying and when it was done it rebooted and then was stuck on the (Samsung Galaxy S2 GT-19100G black screen) and did not want to move. I waited for an hour and a half and nothing happened. When I removed the battery (I could not reset or do anything else) and put it back, the phone turned on by itself and stayed still on the starting screen (Samsung Galaxy S2 GT-19100G black screen)
Now I'm not being able to put it in recovery nor download mode.
Can any one help and anyone knows if the jtag dongle can actually force it to go to download mode even at this stage
Thanks in advance for any suggestion
Ok thank you guys. I think I was able to fix it and revive my phone.

If you didn't done data wipe do it before installing rom.
Which rom did you tried installing? (some roms need stock first and some other roms)

[Q] Samsung Galaxy S II stuck on boot, possible due to Chainfire 3D. What to do?

Hey guys.
My friend installed the official Jelly Bean update(XWLST) on his Indian Samsung Galaxy S II. He rooted it. He then installed Chainfire 3D, despite my warnings. Now, the phone shows the Galaxy S II logo and a yellow triangle with a ! when the power button is pressed, and then it switches off again. He gave it to me to fix it. I've tried flashing using Odin, no use. He used the Siyah S2 6.0b4.tar file to root it. I tried flashing it using that. Kies does not recognize the device, says it's not compatible with Kies 2.0, I tried factory reset from recovery mode, again, no use. I don't know what else to do. Please help me guys. Thanks in advance,

Get a stock rom from Samfirmware with Odin, flash it. If it doesn't work, try another one. And another. And another.
That's the only way you're fixing this. NAND could be borked if it won't take a flash.
Also, you're being rather vague; 'I've tried flashing using Odin' - flashed what exactly with Odin ?

Need help to find original ROM. Samsung galaxy S3. I9300.

I have a Samsung galaxy s3. I don't know what my friend did with that its not booting up. When switch on the display.. It turns on and then it shut down again. I download a ROM and flashed it with Odin. I saw a small improvement . now When I turn the device on , the Samsung logo appears and again it restarts. In think the ROM which I used was not perfect.
May I please get some links for downloading original software .
Thanks in advance

Take it to a repair centre and pay them to fix it, make sure it works on 4.3 firmware before you accept it back.

When a phone is in a hard-bricked state it’s most likely that the bootloaders, which is the phones initial code to launch the phones ROM, becomes corrupted.
The only way to revive the phone is to rewrite the bootloader code.
So basically, if you can't flash a rom through twrp or odin, this service we'll rewrite the os from scratch without having any acces to phone.
