I have several applications, but nothing special and the space was available in SD and I had always facebook, whatsapp connected.
But often the phone locks the screen remains black while the keys light up and am forced to remove the battery and restart the phone so.
Sometimes the desktop wallpaper changes by itself
Today I installed for the third time on a different rom sd, I have very few applications now but I still have blocks with black screen.
I followed all the instructions to install the rom that I found on youtube : Install NativeSD Rom's with 4ExtRecovery HTC HD2 4.2.2 Jellybean by Juicy Boose
Those black screens are called "sleep of death" (sod).
They might be caused by a damaged sd card but most of the time they are caused by a buggy rom-installation.
If you are using original sd-cards ,your card will last a long time until it burns up. Native sd-installation causes many write/read-actions on sd-card that will damage the card after a while. But this happens very slowly, so that you can use your card over years with nativesd.
Your sod's may be caused by false readahed-value, false cpu settings (governour), false formated sd-cards (cluster size) and so on..
Use pixelfreaks roms, macs18max roms or tytungs roms in order to make sure that the sod's are not caused by rom
Maybe your second sd-card isn't damaged.... Maybe device-letter is missing.
