[Sony Xperia M4 Aqua] ardentis:
Hello everyone. Since I haven't seen any discussion about mods, I decided to make this thread to list working and non-working mods and promote good mods.

Post in the format with your variant and firmware number of this post so that I can add them easily. Be sure to link to the mod in the title of the mod.

Feel free to discuss mods and stuff for our device and please contribute

I am (nor is anyone) not responsible for any damages caused by these mods whether they work or not
