I made 5 exe files to run Android 2.3.7 on Nand with Magldr and CWM recovery on HTC HD2. - 1st; run "hd2driverinstaller.exe" both your Windows10/11 PC and VM Windows XP - 2nd; run "HSPL.exe" on VM Windows XP to bypass SPL security mechanism - 3rd; run "task29.exe" on VM Windows XP to erase NAND BqDLlFu.
