Red cross battery tab samsung galaxy II

Hello,
I also had a red cross on the battery icon of my Tab II tablet. After several days of searching, I found the solution after watching how to do it on a website: I removed the battery and replaced it because it was at 0% charge and therefore impossible to start. I handed it over to a friend who tried it with his charger and, miracle, it works. So we tried several different SAMSUNG charger tips while keeping the same original cable, and it turns out that the one that worked was the one made in China, no joke. Best regards.
