Ipad wont start and stuck in recovery mode when connected to itunes
I changed broken digitizer on CDMA version of IPad 4. Before completing the task (adhesive part), I connected the ipad to verify. I saw red empty battery charging icon at which point I disconneced. I put that aside for sometime and when I got back to it, it is no longer showing life. I tried restoring using itunes. I get a 4014 error. I changed the charging port. Same thing again. After 4014 error the ipad disappears from itunes. When I held home+ power for 15 seconds (reset) the ipad reappears with the ipad stuck in recovery mode. But I still get 4014 error. I also checked the battery - its got about 2.6 volts, so some charging is going on. the cable and charger are good because I use them with my other ipad.
Is this a lost cause or can someone point me to a solution? thanks in advance.
