I would say they're probably trash though I don't know exactly why they did that. Did you get them from a reputable place were they one of the big name brands? It may help if you gave the name of them like exactly which batteries they were. On some chargers there's like a recovery option for overly discharge batteries but in all honesty because of the way we use these batteries I think it's better to just get new batteries whenever there's any question about a battery doing something strange. It's just not worth it... you know what I didn't pay attention to the fact that you were USB charging. So maybe it is the mod

I'd suspect there's a problem with the mod. Maybe try a reset or something? I'm not familiar with that mod at all, so maybe search for it on here somewhere.

Try your old batteries (if you still have them)

Also, why did you have to replace your old batteries after only a year?

What batteries and charger are you using? Unfortunately, fully discharged batteries are no longer safe to use, but we might be able to figure out what happened and prevent it happening again.

Well those batteries are toast. Is this the first time you have externally charged? Because your charger might not support that particular battery etc.

Name/specs of charger, mod, batteries, and if they were the exact same kind as the old ones, if you want help in figuring out who is to blame. It can probably be figured out.

Oh who you bought them from, also.

Firstly let me reiterate that trying to bring completely flat batteries back to life is a really bad idea. In fact some damage will happen even if they are taken below 2.5 volts. In the context of safety and the low cost of new cells, it not advisable even if you are able to recover them.

The same thing happened to me with a pair of relatively new Samsung 30Qs. I put them on to charge and when I came back they were both at 0 volts.
It could be that they were both bad cells to start with and they both failed at the same time. It could be a faulty charger.
I recycled both cells and bought a new charger. My reasoning was that if the charger was responsible, it was going to cost me another battery or two to find out.

Did you charge these in your Mod, or with a stand alone charger? I assumed "USP" was a typo and you meant you just plugged your mod into a USB cord because a quick search didn't turn up any chargers by that name.

...I hope he didn't blow his face off

I'm surprised Dripster hasn't been along to tear my previous post to shreds with irrelevant technical hula hoops.
