The BIOS brand is "Insyde".
If need moore details please ask me.
Very Thanks four your help.

can you access command prompt (CMD)?
or
can you access the bios and flash from there instead?
only ever flashed bios a few times (on desktop) but ive always done via the bios screens rather than in windows itself.
.
Hi
I can´t access to CMD, because the screen don´t turn on.
Only can put pendrive and Keyboard with MicroUsb hub. (This turn on the light when push the power button)
But I don´t know if tablet have some method to rescue the bios from Bad update.

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.
So i rooted my Yoga tab just a few hours ago and it went great. Booted back in and installed some apps and started to remove some apps. I rebooted the tablet shortly after and got stuck in some bootloop at the title screen. (Lenovo for those who do) It boots three times and then its just black with some flickering.
I got in to recovery and did (probably really, really stupid) a reset of data and cache. figure that will solve everything. It didn't. But it did not however make it works. Still the same bootloop.
if i leave it on for like 10 minutes, the screen where you choose language and time comes up but i can't press anything. Then everything goes black and flickers.
I was on stock kitkat when this happened and I've searched all around the internet for answers. I don't understand half of the things a read. Reflashing a new bios and fastboot what not. Almost every link in every thread is dead.
I need help and i hope you can help me with a solution too how i can get my tab up and running.
I have no back ups what so ever because i'm stupid so i need just hard reset everything not worrying about saving anything. (didnt have anything on the tab anyways)
Info again:

Hello !
You should try to flash stock KitKat Lenovo Firmware with IntelFlashTool !
Also, you should install some intel drivers : Intel® USB Driver for Android* Devices & iSocUSB-Driver-Setup .
KitKat Firmware must be available under Lenovo site !
Put your device in DNX mode ( press & keep at the same time all three hardware buttons , when device reboot just release power button ... you will see soon "Fastboot starting..." , right now you can release volume up & down ) - connect your device via USB with your desktop and start Intel Flash Tools . Just unpack stock KitKat Lenovo Firmware and select under Intel Flash Tools , Flash file : "flash.xml" from Lenovo Firmware !
Good luck !

Thanks for your help.
Unfortunately, i think it made i made it worse
The flash stopped at 70% and now i'm stuck in a bootloop at the first power up screen.
Can you still get in to fast boot,and are you sure you were on KitKat rom.
try and start your tab in normal fastboot mode (from the recovery console select 'reboot to bootloader' or use from power off the combo keys Pwr & Vol+ or Pwr & vol- one of these two should bring you to the Fastboot/Droidboot menu) and from there tell me what the ifwi entry says... BLADE_21....
Problem solved!
I had to check "Force fastboot sparsing" and change it to 500MB in FlashTool and then it worked. Everything is now up and running.
Thanks for your replies.

Bios Downgrade Tool Query
Hi mate, sorry for such a late reply but I'm struggling trying to get the bios downgrade tool to work on my tablet. Its plugged in and the "fast boot starting" message is showing but when I click on the tool on my pc and start it, nothing changes with the tablet. Is there an obvious step I am missing? Kind of new to this.
Thanks
Hello chaps. Random question. I have searched and searched for an answer but cant find a 100% reliable one. Can our 1050F 10.1 inch run Ethernet on the OTG? I have been liaising with Lenovo tech support via email for 5 weeks now and they are certain it can but I cant get it going with my Plugable OTG/Ethernet adaptor. So, what say you folks? Thanks.
On the Lollipop.
