[XDA Assist] some1s2:
HI,

I bought from Aliexpress GPS based on an android tablet.

the problem is, it came with a very bad android 4.4.2 version: it's a Chinese version, no space to install anything because it has several partitions on the inner space, cant install many apps from google play because of Chinese restrictions, the device is unrooted and I really want to find a new ROM for it.

I was able to install a device info app and to extract some details for this tablet, can anyone help me find a new rooted ROM for this device without all the Chinese limitations? thanks.
