Problema: No da imagen luego de modificar la BIOS
Se logra desbloquearla cambiando el chip TPM y los 2 chips de la BIOS

Sacar la parte superior de la carcasa:
Sacar el teclado, que tiene cuatro trabas las cuales las haces hacia atrás y vas levantando el teclado pero con delicadeza no vayas a sacar las teclas y debajo tienes el flex el cual debes levantar la pestaña que hace presión, también hay una chapa algunas se corren hacia la izquierda y salen otras tiene un tornillo a cada extremo los retiras y levantas la chapa después tienes varios tornillos (6-8)
Sacar la placa: fíjate que tenes de la parte de atrás por debajo dos gomas que cubren los tornillos sacas estos con cuidado y con la ayuda de una punta plana vas sacando la base de la pantalla y bueno observa bien, espero te sirva. Claro esta es para las que tiene dos Gb. de ram. La otra de 1 Gb. es mas simple sacar la placa saca tonillos de la parte de abajo y los que están debajo del teclado y ya puedes sacar la carcasa y quitar los tornillos que sujetan la placa y todos los flex que están conectados como también el wifi.

Bootear un linux ubunto x64 en un pendrive. Meter el pendrive > conectar el netbook > apretar repetidamente SUPR y F9 > tocar las teclas de direccion un poco y aprete enter varias veces, espere un poco y aparecio el logo del sistema operativo para comenzar la instalacion.
Como ven lo importante es que anda
--------
la solucion, tienen que tener en cuenta que cada Bios tiene su propio software, por lo menos la que posteo, es para las canaimas con el bios "EF10MI2"

Buenas, logre instalar Windows 8.1
Primero instalen la BIOS de intel https://downloadcenter.intel.com/es/download/23839/ cambian el nombre del archivo MP0021.CAP a BIOS.CAP, la meten en la raiz de un pendrive y estando totalmente apagada presionan "Fn+R", sin dejar de presionarlo conectan el cargador hasta que comience a parpadear el led de encendido y luego la prenden, esperan un momento dependiendo de la velocidad del pendrive y los deberia mandar a la EFI Shell, si no les funciona el teclado (Como a mi me pasaba) Conectenle uno por usb, sirve bien, yo utilice incluso uno inalambrico porque era el que tenia, escriben "exit" en la consola y hay dos posibilidades, que les salga un menu de booteo
o que simplemente se quede en negro y haga boot, en el caso de quedarse negro en el mismo pendrive donde metieron el BOOT.CAP tenganlo preparado con windows 8.1 grabado con Rufus en GPT (O cualquier sistema que les sirva, pero esa version de windows principalmente porque permite desactivar el Secure Boot que tanto problema da) y les iniciara la instalacion, de ahi buscan como desactivar el secure boot y el uefi
PD: Dentro de la instalacion tampoco sirve el touch asi que se las arreglan con teclado o le instalan un mouse usb tambien https://youtu.be/KQPsLc6BDl0
---------------------
la posible solución es hacer lo mismo que muestra el vídeo, sólo que usando la bios "Phoenix MPBYT10A.88C.0029.2014.0530.1440"

------------------
Con un programador basado en CH340, Si manejas arduino, puedes hacerlo tambien, aunque un poco mas lento, lo compras en ML y te regalan los binarios para unlock
---------------
tiene 1 sola solucion:
sacar el chip del BIOS. cambiarlo o en su defecto si tienen liberador flasharlo.
lo que hice fue comprar un chip de la BIOS nuevo, desoldar el que tenian y soldar uno nuevo!! problema solucionado esas netbook tienen un sistema de proteccion que no deja hacer ninguna modificacion en el setup.(conclusion no hay que entrar al setup)

This is an expected message indicating that when installation begins it may require user interaction. This is the largest software upgrade event ever and we’re managing it so everyone has a great experience. We recommend waiting until your PC receives a notification to upgrade, and then following the instructions provided.
This is an expected message indicating that when installation begins it may require user interaction. This is the largest software upgrade event ever and we’re managing it so everyone has a great experience. We recommend waiting until your PC receives a notification to upgrade, and then following the instructions provided.
Please note that there is no problem
with your reservation or upgrade download. The upgrade download is not
corrupt as some have stated, and you will be notified in the coming days
or weeks when your device is ready to upgrade.
If you are very eager to upgrade, tech
savvy users with the above message can modify the following registry key
to install immediately.
Warning:
Serious problems might occur if you modify the registry incorrectly. Before you modify it,
back up the registry for restoration
in case problems occur.
-
Locate the registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade]
-
It should exist, but if not, create it.
-
Create a new DWORD (32-bit) Value with Name = "AllowOSUpgrade” (without the quotes), and set the Value = 0x00000001.
Once the registry key is modified, close and reopen the
desktop Control Panel, go to Windows Update and check for updates. You should now be able to click the
Get Started button to upgrade to Windows 10.
Note: Windows 8.1 users must go to the desktop Control Panel, and not the modern Windows Update UI.”
