Root Installing Custom Recovery Without ODIN - HELP

[survey4life]

And i also can't boot the phone itself to download an app which will do it.
Galaxy S3 is the phone.
Basically, i can't boot my phone. I can go into download mode but ODIN can't detect it. Believe me i have tried everything. Different cables, ports, drivers, computer, operating systems, ODIN versions.
TWRP is the one i am trying to install.
I have another S3 which can be detected. BUT not this one!

My HOPE is that someone knows a way to install custom recovery with a SD card somehow by going into recovery mode and installing from there.

Any responses are greatly appreciated.

I assume your device is rooted?
What recovery do you currently have, stock?
Odd that with all the methods you've tried, ODIN cannot see your device whilst in download mode.

Nevertheless, if you are on stock recovery, then trying to install a custom recovery via the file on the sd card I'm not thinking will work.
However, I think I'll move this thread into the root forum for your device...maybe others will have some better ideas

it doesn't matter really which recovery especially in your situation no offence. as long as it isnt the stock useless one. what's your recovery now?
