Help CHUWI DEAD :(

[ImADev]

The only way you’ll fix this is by opening up the tablet and using a CH341A BIOS programmer, a SOP8/SOIC8 clip + cable and maybe even a 1.8v adapter. You’ll then need to save your original BIOS so that you can extract your Windows 8.1 key. Once you’ve done that you can write the stock BIOS to the chip.

The BIOS files that Chuwi release are designed for specific revisions. By that I mean that Chuwi changes the internals every few months, which is why there’s an ID found at the bottom left of the tablet e.g. 221511 is day/year/month.

BIOS: J1D_S165C_206 (used in the 221511 revision)
BIOS date: 10/30/2015
MD5: d1138265c8e2825ddcf70b2e7dae2487

BIOS: J1D_S165C_206 (used in the 221509 and 221510 revisions)
BIOS date: 09/21/2015
MD5: e1f93389808e45ae375be9f9d0b8030f

BIOS: G1D_S165_206 (an update for users with G1D_S165_205)
MD5: 3fbb11ac7d77fd81305bc65c88ad414a

BIOS: G1D_S165_205 (old)
MD5: 8706eb20323936956fd9932bf238b5b6

As an example, if I were to install e1f93389808e45ae375be9f9d0b8030f onto my 221511 revision then it breaks the front facing webcam. If I then reinstall d1138265c8e2825ddcf70b2e7dae2487 everything will be back to normal and there will be no “STATUS_DEVICE_POWER_FAILURE” error.

You shouldn’t ever need to update the BIOS unless you’re upgrading from G1D_S165_205 to G1D_S165_206.

Muchas gracias por contestar.

Estoy dispuesto a hacer lo que has dicho, pero no se como hacerlo. Si no es mucho pedir, podrías hacerme un tutorial de como programar la BIOS, o decirme donde puedo encontrar un tutorial?

I am willing to do what you said, but not how. If it is not too much to ask , could you do me a tutorial on how to program the BIOS , or tell me where I can find a tutorial?</span>

Hey, sorry for the delayed reply.

There isn’t really a tutorial for this tablet and I’m not sure what type of BIOS chip it uses. If you could open up the tablet and take some pictures then I might be able to tell you what settings to use. Here’s the links for v1.18 of the program and it’s drivers.

Chrome is incorrectly blocking the website at the moment, so you might need to download the files elsewhere or use a different browser.

Gracias por ayudarme. No creo que tarde mucho en llegar.
Ya he echo el peído de  CH341A BIOS programmer y SOP8/SOIC8 clip + cable.
Creo que las fotos se ven bastante bien.
Necesito algo mas?
Gracias otra vez por ayudarme.

If you lift up the metal plate under the black sticker then you might find some more chips. I’m hoping that the BIOS chip would be under there.

At the moment I could guess that it’ll be the ATMLH408-02DM chip, but I can’t find much info on it. Like I don’t know what it’s purpose is and what voltage it’s supposed to work at.

In the CH341A programmer I can see “ATMEL”, but nothing to support 02DM.

Perdón por tardar del tanto en contestar.
Estos son todos los componentes de la placa base, si hace falta algo mas dímelo.

Gracias.
