[Q] Low/misleading storage CM 10.1.3 - How to fully clean i9300
I don't how to really ask this but I have been noticing a huge problem (for me) with the CM 10.1.3 . It's the storage, after flashing CM 10.1.3 I noticed I had only 1 GB free out of total internal of 11.35 gigs . So I started browsing forums and everything but still can't find my answer, I checked with File Manager the root folders , and there I can see a bunch of files I thought I wiped before flashing but still there.
The timeline of my ROMs is like this
Stock -> purelook HD -> CM 10.1.3 -> CM 10.2 -> CM 10.1.3 *because I thought reflashing would fix this*
Between ROMS I performed factory reset / cache wipe / and dalvik wipe . Only before 10.1.3 and 10.2 I wiped /folders in mounts and partitions /cache /data /*cant get the name of the third one* .
So my question to you guys is, how could I wipe/delete everything everything so my i9300 will be crystal clean without any leftover files to eat storage and reflash cm 10.1.3 and gapps again and start over fresh .
Please be gentle, I am kind of new and not really familiar with all the terms and expresions about rooting . So if you could answer, please do it step by step for me . Thank you very much in advance !
