History

2023.06.24 → Bought from local dealer for 40eur.
2023.06.28 → Arrived in very good condition, like a new, but battery is fully discharged, it seems like it's charging fine, everything seems like working fine.
2023.06.29 → Did full device backup, unlocked the boot loader and installed Windows 10 Build 19044 using WoA project (on desktop it shows 19041, i don't know why). It works pretty good, just need to remove all the bloatware that comes to Windows 10 by default.
2023.06.29 → Managed to activate it with HWID (permantently) with this simple PowerShell command “irm https://massgrave.dev/get | iex”.
2023.06.29 → I've bought Microsoft HD-500 Display Dock especially designed for Lumia 950/XL for 25eur.
2023.07.01 → The dock arrived, have no time to test it yet.
2023.07.02 → Wrote software that shows cpu temperature on Lumia 950 and Lumia 950 XL. Because with the current workaround using PowerShell i was not very happy, coz it's so slowwwwww!!!
2023.07.03 → Tested dock and it appears to be working fine. The HDMI produces full hd (1,920 x 1,080 pixels) output and charging over dock works fine. Have no time to check other periferals such as usb keyboard/mouse, but will test it soon too.
