I found this link Question - LE numbers and applicable models | XDA Forums. I saw (less reliably) it was suggested your phone might be a lemonadept. Perhaps you could confirm your devicecode with
$ adb shell getprop ro.product.device
or another of the methods mentioned here [HOWTO] Find device codename.
Then you might be in a position to look for possibilities of a custom ROMs or /e/ for that device.
