I recently purchased HTC HD2 from someone. It came to me with Android 2.2 froyo installed in it through NAND. Now when I am trying to put ICS replacing froyo or when I am trying to put WINMO 7.5 Mango along with android it doesn't detect USB device connection.
All other features are working perfectly like, phone charging through USB, USB detection for SD card etc.
USB doesn't detect only when I try to run through MAGLDR. For example: when I am switching ON my phone by pressing Voume down key along with power key, colourful screen appears with "SERIAL" written on it. Now when I connect phone to my PC through USB it doesn't change to "USB" from "SERIAL".
Also when I am switching ON my phone by continuously pressing power key to get into MAGLDR mode and trying to flash using the 5th option "USB Flasher Mode", here also I can see just "Wait USB…" rather as per the tutorials it should display "Wait USB…USB".
Now because of this issue I am unable to use my HD2 using WINMO or with any other android OS.
Please help with any option so as I can use the USB feature or to install different OS. My motiv behind purchasing this set was only the customization I can do with the phone. Now without which my motive is getting failed.. Please help me guys ..
First if you have registry backup, apply that and revert back to previous system registry or in case you have not, restore your OS to any previous restore point.
Then restart system, connect USB cable and start it in the particular mode you asked in question (vol down+power), it should try detecting driver.
If it can't, better solution to try finding QUALCOMM MSM driver for HD2 separately is to download windows active sync/htc sync, which might be having these drivers built in, download it and if it doesn't help, restart your system, then try again, it should work, in case doesn't PM me, as I won't be following this post, most probably even you ain't
