  1. Hi Karndev, I’ve installed your custom ROM on my Sumvision Cyclone Astro+ Tablet (same as Momo9) and I’m very impressed, however I do have a small issue that I hope you can help with? Since installing the ROM I no longer have any access to the internal SD Card Storage on this tablet (8Gb) so I can’t install any apps that require large additional data downloads. When I look at the storage under ES File Explorer I can see the internal storage listed but it states that it’s unmounted?
