MY OC 200 V1 HAS BEEN WORKING GREAT AND UPGRADED SUCCESSFULLY EACH TIME THERE IS AN UPGRADE TILL SDN v5.0.30 IS OUT. WHEN I LAUNCH THE UPGRADE, THE OC WILL BE STACKED AT 95% AND SAYS THERE IS DATA ERROR..... I TRIED ALL BEST POSSIBLE, REBOOT IT, RESET IT AND EVEN REINSTALL IT WITH V5.0.30 AGAIN BUT NO AVAIL.

I HAD TO REINSTALL THE OC 200 WITH V4.4.6 BEFORE IT STARTED WORKING AGAIN... IT IS STILL ASKING FOR UPGRADE BUT AM AFRAID TO LAUNCH IT AS IT WILL STILL BRING THE SAME PROBLEM.... CAN SOMEONE HELP ME? OR IF TPLINK CAN FIX THE PROBLEM SO I CAN MANUALLY UPGRADE THE OC TO THE NEXT VERSION OF SDN COMING OUT.... THANK YOU
