On MXQ Pro 4k (S905/1G/100m - blue board ver. 1.0 Date: 151021)
(reset button not solder which makes things difficult)
1/ tried upgrading nand-installed 7.0.2.007 (works fine except multichannel output for AAC 5.1 files) to 7.0.2.008 with gxbb_p200_1G_1Gbit_RealtekWiFi.dtb
==> blank screen after bootloader
2/ flashed android rom ==> installed 7.0.2.008 to USB ==> installtointernal
==> blank screen after bootloader
3/ cold rebooted (did boot on USB to my surprise) ==> installtointernal (sometimes its adviced to run it twice)
==> no bootloader (fortunately there's the nand-pin shorting trick to reflash)
On 7.0.2.007 there was a gxbb_p200_1G_mxq_pro_4k.dtb but it's missing on 7.0.2.008.
Also 7.0.2.008 did nothing to my multichannel output issue (only for S905X in the changelog?)
