Hi; I am new to this forum and this is my first post. I purchased HKV 7" Flatbook with this spec: Processor: Samsung S5PV210 1.0GHz, 7" TFT 800x480px, DDR2-512M Android Version 2.3 Gingerbread 20110921.113041 Kernel Version 18.104.22.168 But then the shop show me upgraded version of 3.0 but wanted to charge me another few bucks which annoy me! So I might venture myself to see if I am capable of upgrade it by myself. Is it too complicated and where can I get the step-by-step to upgrade to even 3.1 or 3.2? Thanks a lot in advance guys hopefully I can manage to upgrade it and go to the shop to show them hell!!
