Acer A1-810 Bootloop of Death

Jan 13, 2014
I have an Acer Iconia Tablet that I corrupted the preloader on while trying to unlodk the bootloader. Now it just continuously loops on the manuafacturer logo. I can NOT boot in to recovery and when I connect to my PC, the preloader connects and disconnects on about a 3 second cycle. SPFlashtool I think can fix it if I can get it to stay in Pre-loader long enough to flash it. Does anybody know testpoints for this tablet? it's an MTK 6589 and I'd really like to revive it.
