    Good day, friend. Thank you very much. My Surface is unlocked. I have looked through and compared many locked and unlocked firmwares for these Surfaces, I have seen that 3F is changed to 3C, but in all firmwares this change is at different addresses. I still do not understand the pattern, there must be a change. Maybe you can tell me how to find the addresses that need to be changed?

                    Hello everyone, I happen to have a Microsoft Surface Pro X 1876 in my hands. It was brought to me by a friends which happen to have taken off the bios chip to test another motherboard.

                    Hey. Sometime ago i bought broken surface pro 4 supposedly it was dead. But turns out it was just a faulty charger.

I already replaced touchscreen and touchscreen board, i've broken the orginal screen when trying to open surface. I already tried diffrent bios files from internet. With the latest one i was able to install the drivers for Surface ME and Surface...
