I have the i9300 but when I boot up into download mode it says PRODUCT NAME: SGH-T999 (not my model, though). I think this is because I accidently installed the SGH-T999 version of cyangomenod.

So to try to fix it, I used odin 3.07 and the
"I9300ZSEMC1"
stock rom file to try to put it back onto stock. Odin "stopped working" and crashed and I soft-bricked my phone (Firmware upgrade encountered an issue message at boot).

I tried again using I9300XXEMC3 stock rom, but odin 3.04 says

And fails. My phone says "unsupported dev_type" in red.


Can I please get some guidance? I don't know what I did wrong. What rom should I flash with odin? Should I try to flash the SGH-T999 stock rom with odin?

I tried following those instructions. I managed to flash the .PIT file. Now I don't see the error message at boot, my screen is just black. BUT I can "sorta" boot into recovery mode (starting recovery message shows for one second, then black screen again). So I'm still stuck.

I can STILL boot into download mode though. And if I try to use CF-Root Odin fails again (same error) and my phone says "unsupported_devtype".

Flash stock rom via Odin .
But flashing a wrong firmware for a different phone may well be a lot more than a soft brick
Did you also flash wrong recovery ???

Everytime I flash the stock rom odin fails and phone says "unsupported dev_type". In Download mode it says my phone model is T999, but it's actual GT-I9300.

And I don't think I did. I think I had clockwork mod recovery, I'm not too sure though.

You have flashed at least the T999 bootloader, which is why it says that in download mode. If flashing a full i9300 stock rom doesn't help then you'll need a new motherboard.

That really depresses me. Are you sure this is the only solution? Because I remember when my phone WAS working I booted into download mode once and it said the same "T999 Model" and I could still use it. This only happened after I tried flashing the stock i9300 stock rom.



I think it's the cyanogenmod installer that flashed this T999 bootloader for me. When I used the cyanogenmod installer it detected my phone as a AT&T phone and I was dumb enough to click "install" thinking it would work for all galaxy S3's.

I think this guide is exactly what I need (since it restores bootloader), but I can't seem to complete all the steps: http://forum.xda-developers.com/show....php?t=2535367

I get to #5 but once I try to install CF-ROOT through odin it says the same unsupported dev type error on my phone.

This is the error I get when trying to use CF-ROOT through Odin3 v1.85:

(along with the red "Unsupported dev_type" on my phone in download mode).


I think it was already rooted though, maybe someone could help me reinstall the recovery (cwm) so I can install the bootloader from that guide I just linked?

Best option is to try a rescue firmware, which might help:

Will this delete my EFS? I remember I backed up efs with this guide: http://forum.xda-developers.com/show....php?t=1852255

I did: "adb reboot nvbackup"

By restoring to "complete" factory settings, won't this efs be deleted? Can I still backup my efs in my 'soft brick' mode I'm in?
