I think it's not recoverable, you can always try using testdisk-like solutions to get data back but odds of getting anything useful is pretty low.

If you upgraded to PR1.1 to PR1.2 (then PR1.3) instead of a fresh installation, most likely there will be another database in the same folder you found el-v1.db and if you received that sms before the upgrade, you can still reach it using that discontinued database.

Good luck,
