Hi everyone
I've try to follow the guide in order to modify an MACHENIKE T90 ：GJ5CN6A
but it can't work。
Can anybody help me?

origin bios link :https://1drv.ms/u/s!AosoYa-vJBdngYJRZe_6NX4_awtqJQ?e=jsExCE

@yaoyulun - Solved or not?

I can't make it

@yaoyulun - OK, then why you mark as "Solved"?? So you couldn't follow guide? Do I need to make the guide better/add something etc?

I can edit for you, and then add to the main guide I made. Please upload for me the entire stock BIOS update package, the ones with flash tools, batch files, EC FW etc, if you have it.
And then please upload for me your FPT BIOS region dump, or is this what is above?

Also, please take one image of each main BIOS page and put in zip for me, just one each of main, advanced, boot, save and exit etc.

i don't know how to make a menu.txt
thank you
here is the link ：https://1drv.ms/u/s!AosoYa-vJBdngYJUrrlWAOlsQPBBVA?e=etDQpi

@yaoyulun - You're welcome. Menu.txt you make manually from the setup IFR text you create, you copy and paste from that and then edit into more easily readable form like I show in the guide.

Thanks for files, please wait and I will have edit for you soon. Wait, you never answered, is the above file your FPT BIOS region dump?

Is this the complete BIOS Update package? If not, please upload the complete package, in it's original form with all folders and all original folder names etc

the bios i git from fptw64 -bios -d

Thanks. On the stock BIOS Package, is that all that came in it originally?

Also, the stock BIOS is newer version 1.05, your FPT dump is old version 1.03 - which do you want me to update for you? If 1.05, update to that BIOS first, then send me new dump (be sure to update to the included EC FW too, following their suggested update method)
I will be adding 1.05 version files to the guide, but if you want 1.03 mod I can send your FPT dump back to you modified

Did you put that on with programmer, or FPT? If you did that's a problem! That's not good, your missing NVRAM volume now.

Put back 1.03 BIOS region via FPT. Then update properly using the standard update method from MACHENIKE instructions.

how about this one

Please use zip or rar - also comment/talk to me if more issues, so I know your thoughts what you are doing etc.
Thanks for new dump, this one looks correct now!

Here is modified BIOS regions for you, both 1.03 and 1.05 - soon I will add the mod files for these to guide (later tonight)

Flash via >> FPTw.exe -bios -f filename.bin

thank you very much
I succeeded in overclocking memory to 2666

You're welcome, and thank you for quick report back! Added to guide

Be careful with some settings, don't try to disable/switch graphic controllers, unless you have flash programmer in hand and are ready to recover
