dell venue 8 pro 3845 windows 8 - Windows 8 General

Hi there,
i have a dell venue 8 pro 3845.To my despair i upgraded to windows 10 and now the tablet crawls to a snail's pace.
i tried factory rest no benefit and i wish to revert back to windows 8. does anyone have an image/iso for it.
i did find this post forums.windowscentral.com/dell-venue-8-pro/330414-dv8p-has-what-oem-copy-windows-where-can-i-find-image-use-winreducer-similar.html
here i found the image but am not sure its the one for my dell venue. plus the bootable usb i make following the above post doesn't boot up windows 8 installer. although i do see the usb in the boot menu (holding power button + volume up) on my dell.
Does anyone know how i can revert back to windows 8.1 (as i dont have a the option on my dell anymore to go revert back to previous windows).
softwares that i have tried to make the bootable usb with the above image are : Rufus, Windows7-USB-DVD-Download-Tool-Installer, usb image tool.
cheers :fingers-crossed:

To boot it, i'm guess you have to get to the BIOS screen. (i'm not too sure, err).
Try pressing F12, and then you should see a black screen, gray letters. (not sure how its setup on WIN7).
It should be an option to boot from the Flash Drive/Removable disk. Let me know how it works out.

I'm testing out the setup now. I know for linux, they do dual boots at the startup screen, asking you would you like to boot linux or windows.
I'm guessing when you install it, it might ask for a dual-boot or delete the windows partition and make android your OS. I'll test it out on my computer first. Then i'll report back to you.
I've done it just change the option to boot off external
It just boots from that and then when its unplugged it boots nornally

I booted it on a Virtual Machine but anyway, there's no option to install therefore once you restart your computer, it'll boot your normal OS. No worries.

Did this on my desktop and also created a VM.
i'm stuck on live android splash screen..............acer aspire 1 w win 7 starter
For those who cant boot to usb due to bios constrictions I found a way around it with this boot manager that has a Run from CD with an ISO file and it works flawlessly.
I might also point to similar thread here although OPs is older there is a lot of other useful info that might be helpful as well.
Guys ... check this out. http://www.android-x86.org/
I'm tested. 80% of the devices is working, except WiFi.

[Q] Install Windows from Recovery Disc

Ok so I will make this short. I got a computer with Windows 8 on it and I decided to dual boot it. When I did Ubuntu booted and I looked with Gparted to see if windows is still there and it said it was. I booted and than windows didn't boot at all. I went back into Ubuntu to check and it said that the partition was empty. I have a recovery image in a hard drive and a Recovery disc, plus a product key. I refuse to spend the money on a Windows 8 install disc because I already bought a copy, I have a key for it. I tried the windows installer thing that is supposed to give me an iso to use but it says my product key can not be used for it. I can get the recovery disc to boot and I tried re-installing from an image file but it doesn't see windows so I can't restore it.

I already tried it. It doesn't boot into it, I think that may be corrupt or something. If I can't figure this out I will just use Ubuntu. Not to big of deal, just want compatibility.

Acer Switch 10 - How to boot Android?

I've wanted to boot and (later) install Android on my Acer Switch.
At first I thought that I can use Images from Android On Intel but it doesn't boot, because the Switch 10 has an 32 bit efi (Intel only supports 64 bit).
Then I've found this thread on xda-developers:
http://forum.xda-developers.com/showpost.php?p=46929905&postcount=16
So I prepared an Ubuntu Stick, but before I've copied the Androidx86 image to it, I wanted to test whether it boots Ubuntu.
And of course, I can boot Ubuntu so it's clear, that the Stick is 32bit efi compatible prepared.
Now I've copied all files from the "android-x86-4.4-r1.iso" to the new created "android"-folder and edited the grub as given.
Then I boot up the Acer Switch, selected the Android and it seems working. But it crashes to the command line as it was expected.
Now I have to type in "exit", but there is the issue. The Acer Keyboard Dock is not recognized by the command line.
After that I've rebooted and retry the same way but with an connected USB Keyboard. Same too. It''s still not recognized.
So, Is anyone there, who got it, to boot Androidx86 on the Acer Switch 10?
In addition. I've also changed the grub setting by deleting the command "DEBUG=1". Then Android boots up to "Detecting Android ...", some other logs and to the blinking curser, but nothing more. It freezes before the Android Boot logo would appear.

Chuwi VI8 Bricked (Blackscreen)

I have a problem, I flashed bios and now my screen is black, I can't see anything and I can't do anything... Can you help me?

You may have flashed the wrong bios.
I had a black screen to, the back-light was on, but the screen was displaying nothing.
Do yo know if windows boots?
You can see that if the power led flashes green a few seconds after booting the device for windows boot, for android boot you have a sound notification from the mailbox.
If you are in that situation, you can try the following process, tell me and I will try to provide you the right links.
I had flashed the wrong bios (single OS without hdmi instead of the super vi8 bios) and had no display anymore, I had to flash again the right bios without display, only by memory.
You need a USB hub with a USB keyboard. (and another pc to get the files needed to reflash)
- I got the bios for the right version of the vi8 (look a the model number on the back of the device) on official chuwi website (in chinese but I used google chome translation)
- I put the bios on a usb key root with the Onda flash tool executable and changed the extension of the bios file from img to fd.
- I plugged the usb key in the usb hub
- I booted windows and logged in 'blindly'
- I pressed Windows key + R to execute a command and typed 'e:update.exe' to launch the flash tool on the USB key, then I heard a sound warning from the flash tool, pressed enter and let the software do its work for 5 minutes.
- I then shutted down and rebooted the tablet by long pressing the power switch.
- I had the display working back with the chuwi logo and estimated myself lucky.
Conclusion : Check the destination model of the firmware twice before flashing!
reply
hi ;
I am in the same situation could you please share with me the flash tool link.
Ok go to this post and download the joined zip : Then replace the bios with yours (file with the fd extension) change .img or .bin to .fd, if I remember well.

Hi I have the same tablet, when it works it is perfect, but the screen scrambles and the console become Un usable and freezes, i thought that it might just be windows 8.1 so I managed to put windows 10 on it last night but today it is doing the same thing. Could some one offer some advice.
Well...
Hi, I was able to fix a v975i tablet that was completly dead, because of wrong bios update, in my case i use a programmer unit and pro skills to weld. Basically you will flash the bios and download the correct bios , but i had to desolder the chip from the motherboard.
