You can attach a dump again i thought.
Because i found out there are somethings are suppressed under Main tab ,they're a little sub-menu or text ,so i try edit. Maybe i took a mistake on somewhere ,it seems not easy as i thought.

Here is bios interface of e5530 i found in internet , the contents under settings is from main tab.

Can you explain what these files are? They were created in root folder of the boot DOS USB right there with your bios_1.bin. I've never seen that before. It all seems a little too coincidental that you didn't want me to know what you changed, how you changed, what you thought changing would ultimately do, etc...

If I'm just being overly paranoid about you not wanting to share what you changed, how, or why then I am truly sorry. Im going to take a look at the module 899407D7-99FE43D8-9A21-79EC328CAC21 and see what if anything could have been the issue. Also, I updated the files in the very first post to reflect the currently updated bios with menus still hidden

Why ask me? i don't know what of them ,i only provided you a mod.
How do you reflash it??why need put it on a usb stick??
Only when you need to going to GRUB shell you need a usb stick.

I've gave you a mod and also told you what module i modified ,if you wanna know what i did ,you should to compare what difference with them , i don't mind you know what i edit ,but you should to research them for yourself ,i'm not a tutor , since i only make mod for users.

You're really thinking too much.

===============edit
>>test mod2<<

I put it on USB flash drive so I can flash with fpt from DOS instead of Windows because it's supposed to be safer. To answer question earlier... I turned of the UEFI setup variables 0x40 (BIOS lock) and 0x42 (BIOS Interface Lock) so that I have bios read permission. I have to turn on ME firmware flash overide at UEFI setup variable 0x21C to flash. The bios locks seem to stay turned off until I turn them back on. The ME flash overide turns back off with the next reboot every time. So, I've dumped and flashed pretty much all parts of the firmware without problems so far

@genius239
Ok, I'm back and have plenty of time to spend trying different things. Feeling a lot more comfortable flashing after being able to recover earlier. I just ask you keep in mind that I don't have another device to use ch341a to reflash a bricked laptop right now. I'm not sure I want to put all my trust in the apk to flash from within Android

What is bios_2.bin? Is that your original modification from bios_1 applied to the bios.bin I uploaded earlier?

After loading bios_2.bin into UBU, I answered my own question. I will prepare to flash and get back to you

@genius239
bios_2.bin appears the exact same after flashed. No changes in the menus, but everything seems to be working properly

@CivicObligation

If you can't see "PCH-FW Configuration" after flash the mod ,it prove that edit ifr file can't unlock hidden items.
This bad bios interface from dell customized was that limit many things for bios edit.

No changes at all in the menus or submenus.

After doing some research into your method, I gave 'er a whirl and it does unlock some of the hidden options, mainly "PCH-FW Configuration". I've actually applied this method to most of the modules and unlocked quite a bit in the Mebx, Raid, and LOM menus. I'm not sure why it didn't work before as I no longer have your uploads saved.

Question for you:
What exactly does enabling the PCH-FW Config option do? Is this the same as "ME FW Image Re-Flash"? I'm wondering what areas I'll be able to flash with both options enabled (if possible due to rebooting after enabling them).

Sorry , i forgot what i've did for your mod ,i should is did a test mod for unlock a sub-menu. It should unlock a sub-menu.
Because I need edit bios everyday ,it's impossible that to remember what every mods i ever did.(Just few minute ago , i found i have did four test mods for this model ,but i forgot what i did.)

PCH-FW Configuration is a sub- menu that included features and information about intel MEI firmware. If you enable "Me FW Image Re-Flash" then you can read/write me region.

Yeah, I know. I was asking if enabling PCH-FW Configuration has the same function or something different.
