Lapbook pro 8/256 how to Linux and fix Black Screen

Please help, I need support. After receiving the parcel, the laptop
worked well. I installed Ubuntu and changed the OS to Linux in the
BIOS. Now the laptop does not turn on.

I wanted to be sure that the firmware is 25q80, the only way out. I have a CH341A programmer. But the laptop is 2 days old and I would not want to solder something on the motherboard.

You don’t need to use solder, there’s an adapter that works directly with the 8 pins in the motherboard.

OK. Thank you for the good news. But where to get the firmware and how to find out the pinout on the board?

How did you write 8Mb bios.bin to 1MB SPI 25Q80?

Hi. I took off and flashed both, 25LB64CVIG and 25Q80CSIG, two times. It didn’t help, the same black screen. I tried with both type of bios. Nothing happend, the same result. Who knows what happen what ‘os linux’ the bios settings set up does?

Serial number of my Lapbook Pro is: Q256G419110397. Pls send me the corresponding BIOS file. Thanks

Hi Albart, have you solved the your problem?

This chips are used for Bios and ME region (or some information for SoC), so you need to flash different firmware for them (if you lost origian ME firmware - you are in trouble) . I think you need to ask support to give files for your serial number or people to make known-good dumps of this chips.

I could not solve the problem and returned the laptop. I could not find anyone who could defeat this problem. all reports of a successful decision on this forum were ultimately refuted.

Can ME region affect the impossibility of loading BIOS?

Yes.

*Why is there a limit of 20 characters.? lol*

Do somebody have right firmware ? How to detect that the firmware is correct ?

Ok, if say it because of IME (security feature from Intel) did somebody try this way ?
I didn’t propose to use Raspberry Pi like a programmer, I mentioned to get off IME.

To determine the “correctness” of the firmware - it should be compared to the original one or it should be flashed into chips and checked the operability of the notebook.
Original firmware is “correct” only for your notebook, for others it may not work (it will differ in serial numbers, mac-address, windows key, ME settings).
ME region rarely causes a laptop not being able to function, usual it is causes long turning on or
immediate shutdown after turning on ((you can even don’t know that laptop is turned on and then turned off) (often laptops works 30 minutes, then just shut down)).

please cope this to service@chuwi.com.

Serial number of my Herobox is: 180G19121062. I have same problem. Could you send corresponding BIOS file? Thanks
