It's exactly the same tablet... We only need to separate the thread if you want to go Windows Only variant or Android only.
The fact that you asked me what is a Allview Viva i10G/Impera i10g/ Ursus/ Onda 975i/975w leads me to believe you haven't read the last 3-4 pages of this thread, and actually, by looking at your signature you have another tablet with a different processor: The x98 AIR!
Note to self: The last time I'm warning people about wrong tablet.

Do you have a licence? Just insert the serial number when requested. Windows is not free you know. Piracy is not allowed on XDA.

Hey guys, I write here if you can help me with the x98 3g of my uncle.
Battery was running out with only 1 hour screen. I upgraded to the Kitkat (Iviva10) and thankfully seems that into enters Deep Sleep.
I have rooted and slowed down the cell at 1GHz. I also calibrated the battery, but the most I've taken has been 1hr 30min / 2hrs screen.

I'm desperate, I do not know what else to try. I think it came defective battery from day one. I talked with a SAT of my country and a battery change cost 60'00 euros. And I'm not sure if this would solve the problem. My uncle says it's too expensive. But I feel sad because the tablet is pristine and spectacular works. It's amazing how smooth running kitkat.

You think that I try to put him W10? Can you think of any way to fix this? If you want I can upload Beterbatterystats capture for you, or some other program that you tell me.
A greeting and thanks in advance :S

BIOS CPU Multiplier at 6x
I have an Allwiew Impera I10G and ity seems that, for some reason, the CPU Multiplier Ratio is locked (at 6x). Anyone knows how to unlock it? The CPU, which is an Intel Atom Z3735D, normally has the ratio at 16x (and turbo it goes at 22x). I've accessed the BIOS and there's noting in there related to the CPU ratios.

Boot UBUNTU from usb disk using tablet with UEFI 32 bits
I tested running Ubuntu x86 from external usb disk on my Viva i10g (Teclast X98 3G clone)
3g modem seems to work, I didn’t test internet but Ubuntu asks pin.
Wifi works after installing driver ( stops working some times)
Sound, touch, Bluetooth,cameras don’t work.

I used the following:
Viva i10g with windows BIOS (uefi32)
usb hub, usb mouse, usb keyboard, small usb stick fat formatted, usb disk with ubuntu 15.10 on it copied from a desktop pc.(or any other linux distribution probably). Android-x86-4.4-r2 iso image ( EFI folder needed) downloaded from

Before you copy Ubuntu to usb install the wifi driver (instructions from )

sudo apt-get install git
git clone h.ttps://
cd rtlwifi_new
sudo make install
sudo modprobe rtl8723be
(remove the dot from the h.ttps)

I used “a small linux distribution on cd” and copied the ubuntu files with “mc” file manager to usb disk after formatting it to ext3

Format the usb stick with FAT filesystem
Extract and copy the EFI directory from the Android-x86-4.4-r2 iso image to usb stick.
Replace the grub.cfg file in the /efi/boot/ directory with another grub.cfg with
the following in it:

linuxefi /vmlinuz root=/dev/sda1 rw
initrdefi /initrd.img

Connect everything to usb hub.
Change the boot order in bios to boot from the usb stick

If you only get to the grub prompt, type ls to view disks and partitions.
Change in the grub.cfg file hd0 to hd1 or hd2 and change sda1 to sdb1 or sdc1

If you want to multi boot, I used “rEFInd” boot manager
and I can boot “windows 10 ” from the internal eMMC and UBUNTU x86 from the usb disk.
We can customize the grub.cfg and add many “Menu entries”
Probably Ubuntu 64 bit is ok but I didn’t test it. Debian 6 x86 booted ok.
