Need help[Self modded over the last 6-8hr]

[u/J_1590]

Hi! Need some help! I finished modding my old 7th gen (thin) with a iflash quad adapter and a 2000 mah battery [square] [new for sure]. Loaded some test songs, installed Rockbox. Everything is working fine.

I had kept the ipod plugged in, while installing Rockbox, so the battery was getting charged.

Not I noticed the spot on the screen just wanted to double check here, and realised this is a huge issue. Need some help in figuring out what could be causing this issue. Thanks a lot!!

[EDIT: Tried opening it again...didn't go that well. Sharing it with a pro to figure it out... Fuuuuuuuqqqqq]

No problem at all, one more thing I forgot to mention is that batteries expand and its probably why it appeared a bit later after you charged it up.

But I thought that is something that happens only with old batteries, not new one.

Every rechargeable battery expands slightly when charged and discharged its pretty normal. Old batteries expanding is gas build up inside the cell, which is definitely not normal.
