Ok just researched Dell support page about my pc... Turns out, out of 3 similar product (3050 tower, sff and mini) only my version (SFF) is MEBx disabled by default... Pretty sure Dell also did something else to prevent it from being enabled again.
@n0k0m3 - show me where you read this, if it's in BIOS, maybe I can still enable for you. Also, please link me to a BIOS from your similar series where you know it's enabled from your research, so I have some BIOS settings to compare with.
I find it odd, maybe incorrect, for someone to say that, when Dell left MEBx options in your BIOS, and AMT settings etc. I see many MEbx settings, and as I mentioned before I checked and see these settings too "Manageability Features State" and "AMT BIOS Features" already enabled by default (This is in your dumped SPI that I'm looking too) Plus, even if "Disabled by default" that doesn't mean we can't enable, much of what I see is enabled, so that's why I wanted to see what exactly is said where you read this and how they worded it, was it Dell saying it, or some random person etc.
Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!

Mine is the 3050 SFF. If you search for the term "Manageability" or "MEBx" you can see that only my version shipped (by default) disabled.
Also, from dell live chat (ProSupport), Dell Optiplex usually shipped with 6 ME options (dell internal service), but it looks like all mobo shipped with the 3050 SFF only has ME Disabled as the only option.
Since we know that the CSME firmware is now AMT-ready, the only other place of failure is the BIOS. You could do some tests if you like. From what I can see, the latest Optiplex 3050 BIOS Updater from Dell, extracted via Dell HDR Module Extractor, includes two BIOS regions.
1_CombineBiosName1_99.1.45._1_System_BIOS_with_BIOS_Guard_[V46]_1.11.0.data.payload --> Motherboard model 07A3 2_CombineBiosName2_99.1.45._1_System_BIOS_with_BIOS_Guard_[V46]_1.11.0.data.payload --> Motherboard model 07CE
You could keep a backup of your current SPI/BIOS image and try temporarily each BIOS in outimage_fix.bin to see if you can access MEBx.
Thanks for the info, I checked the actual BIOS settings already and told you what the defaults were (Enabled)
plutomaniac Good idea to test above! Also, since he mentioned "6" can this be disabled in the FD, maybe that's only thing I'm not certain how to check? I do see at ME kernel, "Hide MEBx update" from user, but I don't think this is same thing I saw you mention on the other Dell ME "3" and "6" discussions. If all fails, then we can just put him on non SFF BIOS, since he has programmer.

Most of these Dell AMT unlocks are simple settings adjustable via FIT. The "ME LOCKOUT" is more complicated as it disables the ME via the FD and presumably also has some BIOS locks of some sort. Maybe these motherboard model IDs refer to SFF or the normal one. If he has a programmer then testing these is very easy and safe. I would use the outimage_fix.bin and just replace each of those two 9MB BIOS regions to see if MEBx can be accessed.
Thanks plutomaniac - yes, he has programmer, switching in/out BIOS regions is OK for test, but final BIOS will need more work to transfer over Asset Tag, serial, all that in NVRAM/Padding etc. how to check/change the ME Lockout at FD, I'll make him a test BIOS using his backup of the proper model, then we'll see if more editing is required or not (Since it appears to be already enabled in BIOS-side, and now at ME-side too)
