No. If there is an external ROM (U12 labeled 8-pin chip) then there is no adaptives in the main IC. I've never seen an embedded adaptive in the main IC on any 8xxxx series WD PCBs.
It was the U12 you moved right? And, are you sure it's correctly soldered on, not upside down or something? Also, did you pay attention to the part of the PCB number after the final dash (E.G. 2060-800067-002) That can make a difference on these. For example 3Tb PebbleB family PCBs aren't cross compatible with the 4Tb & 5Tb Spyglass/Spyglass 2 family PCBs even though they can share the same PCB number.
This board is also very easy to damage since the ROM is right next to the main IC and other components.
There is 8pin IC on PCB, and most of sellers these PCB 2060-80067 rev. P1 say that is enough move this 8pin "bios ic" from originl PCB to donor's PCB, and it's done by my friend experiences electronics service, perfectly really moved, as it's his job on daily basis, and now when connect hdd to usb, PC recognizes connected device but now call it "WD Elements 25AS" or something like that, but not as ago, and HDD not visible, when i go to disk managment , there is message "hdd not initalized" and offer window to choose GPT or MBR, even i choose GPT, it says failed, and still can't see my hdd's partitions.
This is exact PCB i ordered, and ICs i wrote above, and for now is moved this top left corner, 8pin IC - BIOS IC,

And you are right, most of PCBs for usb external hdds is with lock in BIOS IC, but i read there is some models where is lock in MAIN IC too, info about it is here too, and for this model 2060-80067 rev. P1 , that lock is in main IC

It's 100% correctly soldered, not upside down, same as original was. Yes, absolutely i was carefull about exact PCB number, and ordered absolutely same as my original PCB, PCB 2060-800067-001 REV P1 , cause number is on back side, as i'm not absolute beginner , cause my job is IT, but i work in SW developement, not with HW much
.
Yes, BIOS IC - ROM is near to main IC, and absolutely not damaged, as swaping BIOS IC is done by real expert, person who own electronic service 20 years almost, my good friend, and was perfectly done. But seems there is lock in main IC or it's about encryption.

You mention lock, but can you clarify your issue? Are you trying to unlock the drive? Or you are just trying to save the data and it appears encrypted? Many of the newer 2TB Chargers we see these days have microcontroller (MCU/CPU) based encryption. What is your model number? If it's MCU encrypted then transferring the microcontroller should decrypt the data. If this is in fact your scenario you might want to practice on a donor, this MCU has a very tight grid pattern. BEWARE! There is a very high risk of losing your data for good.
I just try to access my 2tb external hdd WD My passport, with PCB number above mentioned. Yes, you are right, it looks like encrypted, and i read in .xls doc someone posted here by MRT company where this model with PCB 2060-80067 rev. P1 is mentioned as one which has encryption , and you are right in MRT doc its called "Charger" model, and seems you are absolutely right that there is encryption by MCU/CPU - so called main IC.
My model is WD My Passport 2TB USB 3.0 external hdd with PCB 2060-80067-001 rev. P1. So if i understood you right way, moving MCU/CPU - main IC , in this case its Marvell IC, from old original PCB to this donor's PCB, will solve my problem decryption my hdd and that can access my data?
Yes, you are right, this MCU so small and seems like difficut to swap, but this friend have many tools and programmers, for re-balling this MCU if necessary re-balling, after moved from orig PCB, and then re-balling, to attach to donor's PCB.
One more thing to mention, is there big problem, if i had ago set password on this my 2tb my passport hdd, is it in this MCU, and when moved MCU from orig PCB to donor's PCB, i will can enter my old password, decrypt hdd, and access my hdd's data?

He said he "accidentally broke the USB connector off" so if that is the whole original issue, a proper PCB swap should work.

Yes, accidently in bag usb 3.0 connector broke, but just swap same PCB not help, cause there is lock , encryption or whatever in original PCB, where is probably saved geometry of hdd, number of bad sectors, password, etc., and just swap same PCB model not work at these newes WD hdds, but needs in most cases move BIOS IC - 8pin IC, but at some cases like seems this is my case need swap MAIN IC - MCU/CPU IC

Well, not if it's a model that is encrypted using the microcontroller
The key is unique and you will need the original microcontroller to decrypt.
You are right, when encyrpted by MCU, then seems need replace MCU from old PCB-original one to donor's PCB? Thank you very much for making this clear!
