you can elaborate more by explaining about what you did before the condition occurs.
rooted/not, stock/mod, etc.

First you should use the XDA device search engine and post in the S3 Q&A forum meant for your device, after looking at the stickies in that forum.
Basically, this could be due to a battery problem ( sometimes just losing connection - cleaning battery contacts or If battery is bulging - needs to be changed) ) or a ROM problem, could be resolved by a factory reset, when using the S3 stock ROM , but you will lose all your data ( so before attempting to do it save everything in your Phones Internal SD card to your PC ( for salvaging later)
But do look in S3 Forum and post only there when it concerns your S3 device.

[Completed] China GT-N9000 Note 3- Bricked After Hard Reset

Hello!
I have a Galaxy Note 3 phone that no longer boots after I tried a hard reset. I maybe stupidly cleared that cache and it froze during the process making me remove that battery. Now it just flashes and goes dead when connected to power or when i try switching on.
The challenge is that I don't know the chip type though its MTK. I also am not sure if its Korean or Chinese clone going by the "fake" label.
I also see this "a3_mb_v1.0." on it and dont know if it has to do with the chip. I have tried flashing with the following roms mt6582 and mt6572 both keep getting the message that the scatter file does not match the chip.
Can anyone help me with link to a rom that works?:crying:

Hello and thank you for using XDA Assist.
We cannot provide technical support nor can other members reply to your posts here on XDA Assist. One thing is clear, however, what you have is NOT a Samsung Note 3 GT-N9000 if it has an MKT CPU, and no Note 3 ROM will work with it. I suggest that you ask your question with all relevant details in the friendly general Android Q&A, Help & Troubleshooting forum at http://forum.xda-developers.com/android/help. That's a good place to start where some members might recognize your device and be able to advise you. Please be patient and give the experts plenty of time to respond.
Good luck!
