well i have a problem i played on my r4 for a pretty long time (i only have my r4 for about 1 year)
but a few months ago is started to get stuck ingame.
now at the moment it gets stuck whenever it needs to refresh to much or whatever
like when i save it gets stuck (the save is succeeded but then it gets stuck) or when i enter something like a house a few times it also gets stuck.

i now use the 1.55 firmware

any solutions or is it just destroying itself?

i fragmentated it a lot of times to fix it nothing helped i fragged it as a 3.86gb,FAT32, 16 kb-4096kb and 8192kb
nothing helped
