for what? you can install linux in emmc if you have root on android, use termux and dd for writing ayufan's image to /dev/block/emmcblk0 directly from android

you must see on PCB and determine which version you have according this post -

I have wrote some manuals in russian language, you can use it if you can translate it - http://4pda.ru/forum/index.php?showtopic=819860&st=340#entry63238627 xenial-mate-rock64-0.5.10-118-arm64.img

I have discovered there are FIVE versions of Z28 box is present, what's your version is? Some of they not able to boot from micro sd.

Bad news for z28 pro owners. There is no possible way to boot from micro sd card, because internal rockchip loader can only boot from SD card port 0 btw on z28 pro sd card module soldered out on port 1... The only way to get working linux on z28 pro is flash it directry to eMMC from android, i will write step-by-step manual in few days.

no, have no luck at this point

This bug described on russian forum 4pda (http://4pda.ru/forum/index.php?showtopic=819860&view=findpost&p=64310568), the solution is to shorten your usba-usba cable to 30cm (http://4pda.ru/forum/index.php?showtopic=819860&st=1160#entry64312087)

You can't damage eMMC via software, just get FULL STOCK firmware and flash it from maskrom mode (do not forget to eject SD card) with AndroidTool ("upgrade" tab)

Z28 PRO MASKROM TESTPOINT

somebody knows where is MAC for wifi stored in?

Yeah, same question, i wonder it unbreakable

Here is my solution for dualboot:

dont forget to eject microsd when trying to enter maskrom or it will try boot from micro sd
