Phone dies after weird behavior; only gets to Odin mode?

[Android Central Question]

Hi,

I have had a lot of problems with my phone (SSG4 Ace).
It all began when it started resetting randomly; it started resetting once or twice a week. I wasn't too worried about it, but then it became more frequent; it got to a point where it'd reset 3 times per day. Battery didn't heat up, or didn't get any message on my phone, prior to restarting. Then, one day, the phone just didn't start anymore: it had a red triangle with a warning sign on the top left. I really hate letting things die, and I try everything I can to fix them; so I rooted my phone using Odin, and reinstalled the operative system. My phone was back to life.

A week later, my phone just started resetting itself again. This time it was an abrupt flood of resettings; it reset about 5 times in 1 hour, then it wouldn't turn on anymore. I'm stuck at the SSG logo; no red triangle, though. It just stays there for hours, until the battery drains out.

I tried a lot of things suggested on these forums, with no avail. So far, my phone behaves as follows:

1) It is stuck at SSG logo.
2) No red triangle.
3) If I plug it to any charging, it gets "stuck" at the symbol of charging; the battery getting filled with "green charge" never pops up, I get the battery with the typical energy symbol in the middle, and doesn't move.
4) Phone will get into Odin mode, and is effectively recognized by the computer and Odin app. I can reinstall the operative system, but it just doesn't look like working.
5) The other combination of keys won't work (volume up - main button - power).
6) Tried using another battery and it didn't work.

That's it. I really hate letting things die, and I'd appreciate any help you could provide. Thanks in advance.

When you say 'reset', do you mean a full reset with consequent loss of personal data, or just a restart?

my bad, i expressed myself incorrectly; reset = restart. there never was loss of data

Okay. The only things I can think of that may be worth trying are Safe Mode, and removal of SD card if you're using one. You've probably tried the first, and are not using a card.
It may, or may very well not, be worth cleaning the Power and Volume buttons with an alcohol-soaked cotton bud.
It's difficult to see how it can be more serious hardware failure, given that all was well for a while after reflashing the firmware, but for all I know that may be possible.

they didn't work
I am suprised it stopped working too, it almost looks like the dying HDDs; they start freezing until they die. Could it be the internal memory dying like that? If so, i don't think there's a way back for my phone
