It worked fine, I rooted the phone enjoyed all the app 2 weeks, later on thought to restore factory setting and I did which was my first mistake, My phone stopped working, it booted and gave QSPT entry downloading error, later I connected the phone thinking of flashing and installing CWM_RECOVERY_FINAL_A21 rom which was an unoffical launch, but on connecting the device window prompted for format, My second mistale I formated it which poped with hardly a 20Kb space and later on my phone is dead but detected as unknow device on my PC(Window 7) and later it was not accepting the drives from PDAnet and USB drivers from Karbonn offical website, researched and installed driver, thou it shows as Qualcomm HS USB QDloader 9008 in device manager, I tried Fastboot, Flash tool to boot the device no sign of boot no lights nothing can somebody help to fix my phone it will be really appreciated.
Waiting for a quick resolution..

You have corrupted baseband files ! unfortunately Karbonn and Cherry Mobile haven't release Source Codes or Kernel Version ! Without Baseband files you can not restore it ! you must update or re-flash baseband and then flash a stock or custom ROM to your Phone ! I Searched alot but no luck yet ! These Companies Don't obey the Law and kernel and source codes are still secret !
Some have been Compiling the codes ! You can wait or just go to service and according to my search it will take 45 days for you to take back your phone !
I think that even the Karbonn Company hasn't the source codes and only the Cherry Mobile Company has it !
Yes.. true . I have suffered from. It.. thank you

Hi experts,
I just wanted to know whether i could able to recover my device or not . Please do help me on this .
Because if i cant , i can move to service center for an exchange of mother board.
About device details : SAMSUNG GALAXY NOTE 4 (N910G).
What happened : Device running Android 6.0.1 (Update 3 rom) which is in snapdragon section .
1. Using device as normal and it was running great for 1 year and 1 month .
Phone suddenly hanged and i was like (hell mood) removed the battery . after that boom nothing works .
Symptoms which i am facing :
1. No boot , No charging sign , No bootloader , No recovery - not even single option is working .
Positive sign :
1. Phone detecting in the laptop as Qualcomm when connected .
and some hope on this thread - which i am not able to recover so far :crying: (may be i am missing the right debrick image)
I am still in a confusing state whether i can able to recover my device or not ..
if yes with the above method or any other way .. above method requires you people expert help as it is missing debrick image (3GB complete similar to N910F debrick image ).
Please and kindly advice me on the my issue.
Thanks for understanding

Hard bricked means a dead phone, so you will have to change the board.
Using the SDCard as a portable Nand isn't practical, you should replace the board eventually..
