https://www.flashrom.org/Supported_hardware#Supported_flash_chips Use GD25LQ64 settings with flashrom, it is supported… and -p ch341a_spi (–programmer command option) for the usb tool…

For the next steps, try to google them a few… Bye…

Thanks for your help But I need also the ROM or BIN file to load / program to my BIOS chipset Do you know where to download it? Can someone help me? I have YEPO 737A which is the same as jumper ezbook 3 pro Is there any YOUTUBE video to see how to do this?

Go to my Drive folder, you have original and modded bios there : https://drive.google.com/open?id=1NDw2nXCUaaIh1uRSG9W8PMrispqMlvuS @+

Thanks a lot So in the software of CH341A there is an option to program the ROM file you gave me ? Is there any YouTube guide to help me?

Google it, you have plenty of tutorials about it… You can flash directly the yepo rom file at address 00000000h (0h) of your chip with some software tools (SPI tools) and the usb programmer… The rom file is compatible with the GigaDevice chip as shown in the Intel ME VSCC table in the rom (see attached picture)… There is no AMI capsule on it so you can directly write this rom file as is on your chip…

You can try flashrom from a linux distro to do it easy if the chip is compatible… You should try to write it with the Winbond chip with the -c setting if it is not, that should work because it is supported in the VSCC table…

You can see me using it in my attachments in the post here : https://techtablets.com/forum/topic/yepo-737a-running-jumper-ezbook-3-pro-v4-bios/page/4/#post-151789

1st page you have the link to 737A_DRIVERS in my 1st post… You have all drivers and bios files related to the 737A I found on the web…

Can I flash my BIOS chip with CH341A? Do someone knows how to use it? Does YEPO or ez book 3 have CMOS battery?

It should be possible with CH341A, but never used it so for 5 bucks, you should give it a try… There is no cmos battery, the main battery cable is maintaining settings, disconnect it and you will have your bios reset…

Try to locate your chip and find the datasheet for it… Pinout is very important to not destroy the onboard chip with bad voltage input… If you don’t have skills to rework your board on failure with a new chip and a hot hair station, take care of it ^^ Common brand is Winbond or so… Good luck…

AfuEfix64.efi jumper.rom /P /B /N /reboot I run this command and my YEPO is dead Help meeee

You need to flash your bios chip from a programmer box through SPI bus… You can also use a Raspberry Pi with the flashrom utility package on the SPI bus… I have done this on some corrupted bios chips I had to recover…

My first advice is to not alter your bios if you are not confident in what your are doing and not aware of how to do it the safe way !

The BIOS of my XEPO 737A is working perfect. I see NO reason to change it!

Well, here we are talking about unlocking settings… I see NO reason for you to change your BIOS if you are not aware about what we are talking about… Original BIOS is enough for you and will work as intended for your machine…

My Yepo is modded with copper dissipator and my flashed BIOS allow me to go beyond basics settings…

Bonjour Hodin, as-tu toujours le même bios? Je pensais aussi flasher mon Yepo par contre je vais me retrouver avec un autre logo au démarrage non? merci pour ton post

Oui, toujours le BIOS du Jumper, vu que ça fonctionne très bien avec, pas besoin de le modifier… Perso, je préfère enlever le logo de démarrage pour avoir un POST complet qui s’affiche, alors j’avoue que le logo, je m’en fout un peu ^^

Hi Hodin, I did those and nothing happened. It still won’t boot to the OS. To clarify, I can install the Win10 without problem but the bios cannot boot to the OS. Upon looking in the CMD command there is no boot manager created even you access EFI\Microsoft\Boot and apply fix boot commands the is no boot manager found in there to begin with. I just gave up finding solution for it that is why I returned the unit even I like the lappy.

Did you completely erased all partitions within the partition manager during win 10 installation ? If you install in a corrupted EFI partition or with a corrupted bcd, your new setup could hang with no boot at all. Try to remove all disk partitions (and hidden ones) before installing Windows. You can proceed in the installation process during install when you choose partition to install to, with no partitions, the installer will suggest you to create all of them for you with rescue partitions, etc…

You need also to choose correct target disk to boot from within the bios… If I remember, use + or – to manage starting order of the correct disk or it won’t round robin to the next one the first time. It happens to me when I fresh installed win 10 on my new ssd …

I used a bootable USB key prepared with rufus for UEFI boot from an updated iso of win 10 creators update… It works like a charm for me…

Regards…

Do you have an UEFI Win 10 installation media ? Your booting disk must be in GPT format and contain a bootable EFI partition. Deactivate secure boot and any legacy mode in Bios and try to install again…

Hi ajoesmith, thanks a lot, your modded rom works quiet good on my yepo notebook. Do you have an idea, howto manage it, booting from a prepared usb-stick with a linux live system. I know the proper way to prepare the stick but when booting the cursors is freezing and nothing happens … May be you have an answer

Hi, as I remember, in order, you must deactivate secure boot in BIOS to properly boot from a live distro. Also, check if you are starting from an USB drive that is correctly partitioned for UEFI boot. I suggest you to boot from an installation partition then make your distro persistent or install it from the key in another bigger partition… You get plenty of tutorials to do this from linux community on the web…

Hy Hodin, thanks a lot for this interesting post. So, to be sure doingthe right thing for flashing the jumper rom from uefi shell: I assume that you have prepared a usb stick with auefi tool an the jumper rom . in my unerstanding of the process it is neccessary to mount the usb in the shell and then starting the flashing process with the following command: *auefi jumper.rom /P * I dont know if its neccessary to set any other paratmeters (like /B for programming the Boot Block or others)? Please let me know Thank you Udo

You have the command lines written in a text file in my bios folder. You can flash the bios from any mounted partition recognized by the UEFI shell. You normally got listed file system partitions at the beginning of the prompt listed like FS0: FS1: etc… you can list and CD to directories and launch commands from path. I have a text or pdf file in my google drive for UEFI commands, you can start from here…

So you don’t need an external usb drive to flash your bios, you can do it directly from the internal memory drive. Simply prepare a folder at root partition in Windows with simple names to remember (that’s why I also renamed some files to have less complicated typo)  ^^

Regards.

Bonjour Hodin, (j’ai vu que tu es français, c’est pourquoi j’écris en français) je viens d’avoir un Yepo 737a. Le SSD que je viens d’installer n’est pas du tout reconnu par le Yepo ni par Windows. En lisant ton topic, je pense qu’il faudrait que je flashe le bios en reprenant la rom que tu mets à disposition. Par contre j’ai vu que tu mettais aussi à disposition les différents drivers. Je suppose que ces drivers ont été utiles car tu as réinstallé Windows sur le SSD que tu as inséré dans ton Yepo. Si par contre de mon côté, je ne souhaite que faire reconnaitre mon SSD, je suppose que seul le flashage du bios sera nécessaire (puis paramétrage de celui-ci), n’est-ce pas ? Quand je rebooterais, Windows devrait fonctionner comme avant ? Merci de ton retour (et merci pour les fichiers que tu mets à dispo)

Oui, tu peux flasher le bios et ensuite normalement cloner ton disque (perso j’utilise MiniTool Partition Wizard Free Edition qui fonctionne très bien). Le bios est super complet et tu as des options pour quasiment tout sauf l’overclocking mais sur SSD, le système est relativement rapide pour ce genre de notebook.

En ce qui concerne ton SSD qui n’est pas reconnu, je ne sais pas si il le sera après le flash. Vérifie déjà si tu l’as bien monté, mais de mémoire, effectivement il faut désactiver une option pour qu’il soit reconnu par la suite (il me semble que ces options sont également disponibles dans le bios original d’ailleurs). Si tu te trompes dans les options et que ton portable ne s’allume plus, reste appuyé sur le bouton power pendant plusieurs secondes pour réinitialiser le bios ou dans le pire des cas, démonte la face arrière pour débrancher le cable de la batterie pendant quelques secondes pour reset le bios…

Cordialement.
