So, I tried to do a clean wipe of my Galaxy SII I1900 variant and flash in Paranoid Android's latest build, and everything was successful, but I realised the clean wipe wasn't that "clean". It did not wipe out anything from my internal data, so my app data and photos etc were not wiped. I tried to wipe it again but it doesn't work somehow.
For some reason my brain thought formatting the sd card means formatting the internal memory (lack of sleep), and after formatting it, neither my phone nor my computer could detect the sd card anymore. I formatted it using the CWM I think (I held power button and chose reboot->recovery), there was no option to format it in any format, it just formatted right after I chose the option. I am not sure if I plugged it out safely but there wasn't any notifications about it being plugged into the computer.
I don't have a sd card reader and I don't think I have any spare sd cards lying around.. Any help for this poor soul here? :/
