PLEASE HELP ME: I accidentally rooted my phone and entered in soft-brick (ODIN)

[cinna 1]

Hi, please help me.
I have a SAMSUG CORE 2 SM-G355M and after all kinds of things, the phone is stuck in the Kies error ("Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again") BUT KIES PULLS ME INTO A "UNKNOWN ERROR".
I'm from Chile, and I downloaded plenty of firmwares, all original, from sammobile, even a few that were not from my country, but nothing works.
Even recovery.tar files.
Even 5-files firmwares, or .pit files.
Depending the condition (With or without battery, kies installed and unistalled, etc), is a diferent error, but now is just "Complete(write) operation failed".
I have tried like, 15 versions of odin, and only one thing has changed:

In Download Mode, the "CURRENT BIN" in the start of this thing (a month ago, I think), it was "CUSTOM", but trying with certain "Recovery.tar" changed to Samsung official.

I can't enter Recovery mode, either.

PLEASE, I have problems expressing myself in English, but I will try to make work this thing here, since in other forums in Spanish no one has helped me.

Welcome to the forum as a new member! I can't help with your recovery problem, not smart enough there, but just wanted to say your English is very good, you have nothing to apologize for there

You probably have already gone here, but just in case:

...failed again.

Sorry about that. While we're waiting for somebody here to chime in, have you visited XDA Developers site? This is really what they do there and you may find something to help.

i will, i was reading some, it's hard to understand it; the terms itselves like odin or firmwares are really new terms for me, imagine all in english ;_;

You were doing so well in English I forgot you're a Spanish speaker Google Translate may help.
