Normally, we upgrade HTC HD2 Windows Mobile ROM using RUU with USB cable. It is faster than using SD card method. Then why do we need to upgrade HTC HD2 ROM through SD card?
You cannot upgrade HTC HD2 Windows Mobile ROM using RUU when you cannot even connect through Windows Mobile Device Center or ActiveSync. And the only way to remove HSPL is to use SD card upgrade ROM method with official HTC HD2 stock ROM.
My home broadband connection, Streamyx is having issue again. It keeps disconnecting and connecting (DSL is not connected issue). So it is time for me to use my HTC HD2 as modem again. But I don’t want to use wireless connection this time, but going to try Wired Tether for Root Users. It is the same as Wireless Tether for Root Users but using USB cable instead of Wi-Fi connection. It is good for single user usage and can charge your phone at the same time.
There were several readers who had issue during NAND Android installation. They faced Error Description: USB init failed ~ Info: .\RSPL\RSPL.cpp (723) issue. Basically, this happens on Windows XP which uses ActiveSync.

Introduction
“Warning, low battery. Err… Why did I forget to charge my mobile phone yesterday night?” Luckily, I have Monaco Mobile Phone Solar Charger with me. It is a solar battery charger. With it, you can charge your mobile phone like Samsung Galaxy S, Apple iPhone 4 or other portable devices like Apple iPad and iPod which don’t have replaceable battery. A nice backup battery for them. Just plug in the USB cable and connect to your phone. Your phone will be come alive again by getting power from it. For me, I use it to charge my HTC HD2 anytime and anywhere.
