FastBoot not work for installing DualBoot

[Oguz Kekec]

hmm can you get into dnx mode (power off the device then – press and hold volume down , volume up and power button) ?

[Ignacio]

When I press Vol+, Vol- and Power and hold, we can see the error BOM selection switch (SW1B1) has changed FORCE_WINDOWS / BOM3 1 mode. The system will load relative setup setting and reset in three second).

This message appear if I have installed “DualBoot Bios C6J6 Tested And C8J7” If I install the only windows bios for C6J7 I can see other message.

Please check this first:
Power op the device and keep pressing ESC with a keyboard – this will get you into BIOS settings..
Go to BOOT , then see if Fast Boot is enabled or disabled..
It should be disabled..

[Ignacio]

Thanks for you response.
I looked the BIOS and yes, the fastboot was disabled t, but I’ve activated and when i turn on the tablet with vol + vol – and power, I can see the same text.

I tried to activate all opcions of fastboot too. But the result has been the same. :S

[Oguz Kekec]

Hmm fastboot option should be disabled –
Have you runned the “右键点我选管理员身份运行.bat” file from “dualboot bios tested C6J6 and C8J7” in windows?
that should update your bios

[Ignacio]

Yes, I runned this .bat in Widnows. And If I’ve enabled or disabled the fastboot the text is the same. I don’t undersand.

I tried to reinstall the “dualboot bios tested C6J6 and C8J7” repeatedly, but the result is the same.

Could be the version of the tablet the problem? My tablet is C6J7 and the dualboot bios tested is tested in C6J6 and C8J7.

Hmm that i dont known.. But mine is c8j6 and that’s working?
Let me see if im correct:

You have a windows teclast C6J7 – and you want this to be dual boot /android and windows..
When you press & hold volume down/up and power button yuo get into DNX mode…
Here you open “Manufacturing Flash Tool” from you pc and trying to flash? OR is the error there already when you go into DNX mode..?

[Ignacio]

Is to enter DNX mode.
No problem of “Manufacuring flah Tools” because I can not get to use.

To use the “Flash Tools Manufacturatin” You need to turn on the tablet with “Vol +, VOL- and power” and when you do a text will appear (I guess that’s the DNX mode).

When this text appears you have to connect the tablet to the PC with the “manufacuration Flash Tools”.

I would not that text appears. When I press (Vol +, VOL- and power) appears me “BOM selection switch (SW1B1) Have you changed FORCE_WINDOWS / BOM3 1 mode”. This error is 3 seconds and then start Windows.

[Oguz Kekec]

Hmm okay… And yes thats the dnx mode…
And when you get into dnx mode, it should just say dnx mode something something…

I think maybe its just a setting problem in the bios..
Can you maybe take picture of all settings in the bios and post it here..? Thrn i will compare with mine..? And if its the same then we can be sure that its not the bios settings…

And just so you known , im not a dev. Or something like that.. Im just a dude that have bought almost the same product as you (but i a have it education) and just messed with it..

Hey All,
I’m trying to reinstall/repartition my device but i can’t seem to get it into DnX mode. I get a short lived screen that says “DNX FASTBOOT MODE..” but the flasher never moved past waiting for device. I’ve attached 2 picture of what i get. I’ve tried entering DnX both with the vol +/- + power button and also by setting it in the bios and doing a save settings then save and exit. Any help would be appreciated! My end goal it is shrink android and reinstall windows to use that larger space.

Thanks
Spencer
