i typed in "fastboot oem writecid HTC__001" which didnt have any problems and changed successfully
then tried to proceed with Step 1,2,3 and the rest after that were problems, such as Main Version Older and unable to flash the rom.zip
I figured that this was because my bootloader wont get "RELOCKED" permanently
problem here is i cant switch out of CID : HTC__001 back to HTC__044 to relock
i know i need to get back to HTC__044 now...
any form of "RELOCKED" is temporary, and when I reboot the bootloader, it shows "UNLOCKED" again and i've actually never seen HTC__044 since changing to HTC__001
