I don’t know if you’ve got a new Chuwi tablet or an older one. If it’s a new one then it would of shipped with J1D_S165C_206, which is the latest BIOS avalible for the model. If you apply the wrong BIOS to the wrong tablet then it’ll break multiple things, as you’ve found out.

1. Copy the correct BIOS files to a USB stick formatted as FAT32
2. Plug it into the tablet
3. Plug in a USB keyboard
4. Power on the tablet and tap the ESC key until you see the menu
5. Select boot manager
6. Select the USB drive

That should make it restore the BIOS, but you’ll probably have to get the correct Windows image for your tablet now.

If I knew what revision your tablet was e.g. 221511 then I might of been able to link you to a backup that contains both Android and Windows.

I bought it in Dezember 2015
I think it’s a new one. Wich Bios I need?

And how i can find out the revision?

Look at the bottom left of the tablet. My tablets a Vi10 Pro (221511) and I know that it uses J1D_S165C_206.

You probably need J1D_S165C_206, but you installed an older version. Either way, if you let me know the ID then I might be able to give you some links.

I know that the RAR file is titled “OLD BIOS” but it’s actually the new BIOS that applies to 221509-221510 systems.

I’m fairly sure that the 221509 revision is identical to the 221510 revision, so you should be able to use the following backup image.

The backup is for the 32GB version only and it’ll restore Android and Windows 8.1. I found it on a Russian website, so credits go to them.

You’ll need to install Macrium Reflect on your PC and create a rescue USB. I think you can copy the .mrimg to the USB once it’s created too, so then all you have to do is boot to the BIOS (use the ESC key when you boot) and select the USB.

If you do it the Macrium Reflect way then you won’t have to mess around with partitions or command line stuff.

In the Boot Manager i can’t find the USB but in the Boot from file i can?
What know?
Gut to windows in cmd and startup.nsh?

[ImADev]

This should help.

You can obviously skip the download for the BIOS file from techtablets. Use the one I linked to instead.

In the video Chris went from G1D_S165_205 to G1D_S165_206 as he’s got an older model.

Its look like that the USB only works if i format it on a Windows PC.
I have format it on my Linux PC…

With Windows it works

[ImADev]

So now that the BIOS is restored you’ll need to create the USB recovery image. There actually is a premade one that you could use, but the instructions are in Russian. You could look at the pictures and translate the text online though.

Read my post, and follow instructions in the correct sequence (don’t skip steps, re-arrange steps)

http://techtablets.com/forum/topic/tutorial-how-to-install-windows-10-only-my-way/

 

Tips: Do it under windows, try and not use cheap Sandisk flashdrives (don’t ask me why), and use an original untouched MSDN image of Windows 10 (x86 – Home edition)

The latest original image is:

<label class=”detailtitle”>File Name: </label><label id=”filenameLabel”>en_windows_10_multiple_editions_version_1511_x86_dvd_7223716.iso</label>
<label class=”detailtitle”>Languages: </label><label id=”languagesLabel”>English</label>
<label class=”detailtitle”>SHA1: </label><label id=”sha1Label”>5D406D89656F8548FD0F410BD66DE59BE05B081B</label>

Just search for that ISO by name on “places”, and check SHA1 if you want.

Hello!
So all work fine accept touch.
I need some help.

So what I do:
I reinstall with Macrium Reflect Win 8.1 like ImADev say it me.
=all worked fine

Then I try to install Win10 like Eras say me.
= No touch
= No WIFI

Again Macrium Reflect and Win 8.1.
then I make with doubledriver tool a backup of Win 8.1 Driver
then I install Win 10 like Eras
in Win save monde I install with dd the Backup of Win 8.1 Driver

Know I have WIFI an all looks good but also no touch.
some ideas?

[ImADev]

This is what I had to do. Your version of the Vi10 might use a different touch screen driver though. Try manually installing the driver like I did anyway.

I could kiss you my lovely boy 😀
That was the treiber 😀
Thanks a lot.
