HD2 certificate/component problem
Up until a few days ago, my HD2 was working fine. Then I tried to install Android. I used the one that you just copy to the storage card and run a file called zharet.exe ( !!NOT HARET.EXE!! ). I think it was Cotulla's ROM. First time, it crashed. Second time, meaning after I installed Radio ROM version 2.12, which is required (more specifically, 2.08 or above is required, but 2.12 was easier to find), it started and installed, then rebooted. Third time it worked and was able to send a text message to my stepfather. I switched back to WinMO to ask him if it got there, then I started Android again. It crashed, sending me to the boot screen of WinMO. Upon this start I was no longer able to run many files (executables), the running of which resulted in the message "The File *PROGRAM NAME* cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. If the problem persists, try reinstalling or restoring this file."
I have tried numerous fixes:
Reinstalling the applications
Seeing if .NET Compact Framework was installed; the phone claimed it was, but I couldn't find any trace of it and so I tried to reinstall it. I was not able to, so I "uninstalled" it from the phone, which still thought it had it; the operation took no time, so I doubt it was there in the first place. When I tried installing it to the phone again, it said that this version was already in the ROM. Also tried installing an older version of the CF, but it just said I had a newer version.
Switching memory cards (3 different ones)
Renaming the memory card and restarting, a fix recommended to some other people who had a problem with similar symptoms. It refused to cooperate and said that the memory card could not be renamed.
My next step will be to rename the memory card using a device other than the phone itself.
I don't want to hard reset as I wish to keep my messages and contacts, but if that's what is needed to "un-half-brick" this phone, I will of course do it. The way it acts now, I might as well have kept my n95.
It is worth noting that HardSPL should be installed, as it was required for the Radio ROM flash.
EDIT: HardSPL install IS verified, boot screen reads as follows:
In this thread, Gargoyle999 is describing my exact problem: forum.ppcgeeks.com/showthread.php?p=1882858
Keep in mind that this phone is Norwegian with Telenor as its carrier, although the phone itself is not locked and capable of using any carrier.
EDIT: The files that may not be run are mostly third-party ones, like MorphGear, zharet, Google Maps and so on. Most programs that came with the phone, like Copilot, Footprints and Opera work.
I am not too familiar with XDA, so forgive me if I am posting in the wrong section or making some other rookie mistake xD
