Samsung n3n sm-n750 download mode nither responding in odin mode or in kies mode.

I had rooted my note 3 neo sm-n750 device twice before through odin. i had never faced issues as i m having now.
i had rooted my n3n earlier and also revert it to stock through odin, but i mistakenly installed "INS" version of rom where my devicebox indicates "INU". after that i re-tried rooting same device through odin method. my device connected perectly also i dont get any error throughout the process but my device download mode not respond to any update so odin process stuck. i tried every wayout available at android forums i got nothing helped me out. so i decided to root my device by apk available in market. i installed kingoroot and it rooted my device properly. after that i installed flashify apk to flash recovery and after that i got a pop-up asking to reboot in recovery. i pressed reboot and it wont reboot into recovery whereas it stuck at n3n startup logo. now i m not even able boot into stock recovery, and my downloading mode also not responding. i tried kies firmware installation and updation process. my device connected perfectly downloaded require files but stuck after downloading procedure as my downloading mode isnt responding. i have only option to boot in download mode only.
please help me.
Thanks in advance.

Odin mode disappear in 5 sec

So my phone is ROMless for now. My twrp keeps crashing when flashing any custom rom , So my only option is to install the stockfirmware through ODIN. Im using the latest odin on pc so its fine , the problem is the ODIN mode on my phone. I can boot to Odin mode but it will disappear after 5 second. It will restart the phone but in my case yes it will restart but just stuck on the samsung start logo. :crying: I tried to search for solution but i found nothing. I have no options left , TWRP doesnt flash rom then odin will just disappear . If someone know how to fix this, please tell me as soon as possible.

Stuck in boot after trying to flash TWRP with Odin G610F. Please Help!

I messed up big time trying to get into TWRP by flashing it with odin and now I'm stuck. The main problem is that the home button on the phone doesnt work and I cant get into download mode anymore. Please help me out coz everything is closed in the lockdown.

SM-T500 galaxy tab A7 stuck in download mode with error

I couldn't find any dedicated forum for galaxy A7 tab so posting here.
I was trying to install TWRP -
1. First I installed vbmeta.img using USERDATA option in Odin.
It wiped all data and restarted the device.
2. After that I again put it in download mode and tried to flash TWRP using AP option in Odin.
I guess somehow OEM unlock got disabled (i am guessing when it rebooted in step 1)
And now I am getting error as attached in the image.
Now I am trying to install stock firmware but now Odin is stuck at 'setup connection'
I tried reinstalling usb driver and restarting PC but nothing is fixing the error now.
Please Help me unbrick the tab.
The tab keeps showing the same error no matter what I try. I am not even able to turn the tab off now.
