Coyotes,again you are a big boy and are welcome to formulate your own plan. As I've said,I'm not sure why you ask for advice at all,as most of the time you just explain why you don't want to follow it.
HTC cell phones are my hobby.for the past 4 years, Ive done nothing but mess with just about every HTC phone that there is,and up until recently vzw has been my main carrier. The advice I give is based on this experience and what has worked for me. Other things may work,but I post what I believe to be the most safe, reliable,and likely to work the first time.
In a nutshell,Santod has told you to flash a new rom,wich will fix all your other bugs and we have been telling you to do here since you did the dirty flash you shouldn't have. I'll be surprised if this also fixes your sim issue,but you never know. The next bit of advice to install the stock rom and recovery is similar also,as I explained to you the stock recovery can wipe the phone much more completely than any custom recovery.
The prollem here is that you're still on a mismatch of firmware,and simply flashing firmware.zip from the ota may or may not fix that issue(IIRC,you s offed a while ago and are on an old firmware base,so flashing the new firmware.zip will just further jumble things up). The mismatch may or may not cause you any percievable issues,so you may be 100% happy with those results. However,it is my opinion that the phone will operate better with everything matching,wich is why I recomended to run the ruu over the simple stock rom/recovery install and let the phone ota to current. Again,this is simply my opinion as to what will give you the best working device.
I'm not sure why you are so afraid to run the ruu,or why you think the process I've recomended is so complicated. But any rate,I wish you luck in getting things sorted
