Dear, I got this Boxchip A13 unbranded from chinabuye,http://www.**************/a139-9-ca...id-4-0-8gb-hdd-a13-1-0ghz-cortex-a8-tablet-pc, similar to the Momo9, the problem I got on it is that playstore don't allows to install any app using googleplay/market app. After some search I got some thing, the tablet have a folder /oem with a oem.prop file. Inside the file have a simple line "persist.sys.locale=Asia/Shangai". Some other forum says that in build.prop you should change the country, locale and language to ocidental like America/New_York, us, en. But the /oem folder is a link to the mount point /dev/block/nandi that is a cramfs ro,relatime partition/image, that could not be modified. The solution some told me was to get the original ROm and modify it or get a modified for a branded tablet with the same configs/spec of mine. My question is, your Rom could serv to my tablet. Its a 9 inch Boxchip allwinner A13 1.0Ghz 521MB DDR3 8GB capacitive.
