It just won't show anything, just a black screen. I kept it charging for like 4 hours, still no signs. I tried like all of the stuff i could find by google (holding power+home, power then home, connect it to PC etc) but none worked. Is there any way i can fix, i mean, before the battery dried out the phone was working fine.

Lithium-ion batteries are very temperamental, and have a tendency to catch fire or explode if overcharged, or if over-discharged, then recharged.

Given the age of the device, if it emptied the battery and you let it sit for a while (days, weeks, months) before recharging it, you may have triggered the latter state and the charge-protection circuitry has killed the battery to protect you from a fire. Li-ion batteries will slowly self-discharge when unused, and this self-discharge on an empty battery can drop it to a level that the charging circuitry considers to be over-discharged.

Never allow a device to sit after being completely discharged. Recharge it immediately, even if it's only to 10%. (Ideal long-term storage charge...
