Hello,
Thank you so much RsM !!
It worked !
I have access to advanced menu too.
So much options but I did not change anything for the moment... Just trying if Windows is booting !
Thank you so much to everyone, especially RsM and Ciber Slash for your help !!!
Well now I have Teclast logo at boot ... not a big deal for me !!
This is how I did :
1) I received the Teclast F6 pro bios from Rsm by mail, saved it on my pc.
2) I used the CH341A programmer + SOP8 clip.
The big issue I had was the clipping was not good enough. I had a lot of write timeout failed although the chip detect was good but writing ...
After many attemps, I succeeded ... I did a "verify" from the software to check if the writing was good. I also checked with FlexHex software to compare the file provided by RsM and the one I saved from the chip after writing.
As I failed many times, I thought at some moment that my chip was faulty... but I tried more and succeeded... I nevertheless have bought the Winbond 25Q64FVSIG chip from Aliexpress just in case (I will reveive 5 of them in 2 weeks...).
This is my story !!!
Thanks again for this forum where I finally found some help !!
Regards and stay in good shape !!
