So recently a relative purshaced an LT901. Just today we found out that the tablet can not use a USB dongle unless it is bought from the same guy he bought the tablet ( Tried using a Huawei E173 - which is on supported devices). I also cant access recovery mode no matter what combination of keys I try ( I hate black market deals ) so the tablet's software mustve been messed with. My questions are: Has the said guy who he bought the tablet from restricted most Mobile Broadband devices? How am I supposed to remove his restrictions if I cant even access recovery mode?
