I can get to download mode and to another mode which offers factory reset etc..
I won't be able to help, but maybe this COULD help:
1- are you still on hboot 1.44? that COULD give a glimmer of hope, as you could use revone to unlock without wiping
2a- if however you are on hboot 1.54+, then (to the best of my knowledge) you need to use HTCdev to unlock, and that WILL WIPE everything
2b- if you are on hboot 1.54+, you could use a Java Card to get S-Off, then downgrade to hboot 1.44 (NB: I do not know
if a Java Card wipes anything!!!)
why hboot 1.44, because it allows for "fastboot boot
<name of custom recovery>.img", where you would be able to use adb commands to pull the sms database (I think it's stored in "/data/data/com.android.providers.telephony/databases/") though you would still need to find a way to decode the sql db.
I use this: https://play.google.com/store/apps/d...pRestore&hl=en
to backup SMS messages to an xml file (doesnt work for MMS), but you need a functioning ROM for that.
