i see many topics about defective ak2i or dead after update, instead to trash it if you want you can ship back to us for replacement even if you bought from another continent lol . BUT only genuine real acekard 2i with Serial anti-fake number on the back, not clones, no broken or fall into the water. Actually we cannot replace older Ak2i with window chip first stock of ak2i and Aki with serial number due these flashcard have more than 1 year life. UPDATE: due we received 3 really good made clone of Ak2i with PCB same as original, but only plastic a little different, if we receive a fake clone aki we will contact you and for all the warranty process we will replace only after acekard team replace to us. Sorry but we are not going to replace fake Ak2i , is not good for original team too. Ship back to us with method you prefers, probably a simple airmail with white plain evenlope is better to cut costs. We will reship back to you for free via airmail too. No tracking is possible but if you want for 2$ i can pay the registered airmail with tracking option. If you are interested just reply this topic and i will give you the return address for replacement via private msg , you can also contact me by private msg too ! ciao!
