Can't turn on phone, phone not displaying memory (No OS??)

I need help.
I'm running this rom and lately my phone has just been rebooting randomly, well now its switched off and I can't get passed the "Samsung Galaxy S3" on boot. I don't even get to the omni animation.
I booted into recovery in an attempt to flash an old nightly but when I click on install TWRP says 0 internal memory and 0 external memory?
What do I do?
Please help, thanks.
Edit - Another thing, I went to reboot while in recovery and it said I had no OS installed?
It just occured to me that I could probably flash a rom/nightly via odin, since I can get into dl/recovery mode, but since it says 0gb int and ext when in recovery, will this work?
Not detecting memory seems like a hardware issue to me, but I know literally nothing, just asking/helping/promting
ps when i plug in the charger, the battery logo comes up
although its empty (not green), and it has a little circle in the middle to indicating loading of some kind, but the circle doesn't spin, like it's crashed.
i know i have at least 50% battery because it says so when i enter recovery
Recovery format sdcard system data cache .
Boot to download mode flash stock rom via Odin .

PLEASE HELP! Bootloop, Stock Recovery, USB debugging off :(

Can anyone please help me
Before my phone got bootlooped, I used to change the build.prop in
root/system/build.prop to add a navigation bar to my Samsung Galaxy S DUOS GT-S7562.
I added qemu.hw.mainkeys=0 at the end of the texts.
And do a reboot and now my device is bootlooping
I only had a stock recovery, and do the factory reset but still no luck.
It only boots to the Samsung boot animation.
I tried to enter the Download Mode to use Odin but it surprised me that
I can't even go to USB state so it's impossible for me to do it also.
And lastly, I don't have a backup also.
But I found a firmware exactly for my device.
Can anyone please help me
ICS
Found this old thread while looking for the same symptoms. I added just this line to my Android box (KM8P) and the next time it rebooted it was forever stuck at the MBOX logo. Cache clear and factory reset did not fix it. I had to flash the stock ROM back on, then TWRP and magisk and set everything back up again.
The soft keys appeared after the build.prop mod so it seemed to be working.

Yesterday everything was working good untill i installed a Magisk Module ( AR Core platform) and my device went to bootloop , i booted to TWRP to reflash a new OS , i wiped the current OS ( i dont keep backups) .. i did'nt realise that my battery was low and after i rebooted the phone to flash new OS it is now always stuck in FastBoot . No matter what i do . Then i relocked my bootloader , got the Red Warning , pressed volume buttons STOCK Recovery appeared but i can't boot into it either. what should i do ? the phone is not charging in FASTBOOT Mode , neither when i switch it off and plug it in charger (it boots into fastboot). I even tried the batch file method cycle to charge it for 10+ hours but still no luck. Need Urgent Help

Problem after factory reset

Hi,
i'll try to explain the problem.
I use the Galaxy s6 SM-G925T and wanted to reset to factory defaults. The phone is in original state. So no custom rom, not rooted or any other modifications. The Battery has been replaced because the old battery had to be charged every 4 hours. Because the new battery does not lives much longer (maybe 6 hours) i wanted the factory reset.
First using the volume-up home and power button, i've choosen wipe cache / factory reset
Down the bottom of the screen was a text : No Support SINGLE-SKU - Supported API: 3 - dm-verify error
I continued and wiped the data
The system returned "Data wipe complete"
After the phone rebooted the system restarted, only to show the blinking SAMSUNG text.
I left the phone blinking for about 1 hour, nothing happened.
So i loaded the official systemfile : CF-Auto-Root-zerolte-zeroltexx-smg925f.tar
using Odin3_v3.14.1 i was able to flash it onto the phone.
After rebooting now the red android puppet showed up and the cf-auto-root program fnished without errors but the phone still wont start
Is the phone bricked or is it still possible to restore factory defaults and get the phone back to work ?
Thanx for all the helpfull answers !!
