This was an absolute scam, I plugged it into my console and it wouldn't even sync. Someone told me to put it in the freezer because it will recharge the lithium battery inside and now it won't even turn on. Im never buying another XIM product this was not worth the $200 I paid on ebay. The XIM1 sucks
I think you may have gotten the wrong instructions, it depends on what firmware version you are on. If you are on any other version of firmware besides XIM Revision 10-26-2007, you put it in the freezer. With XIM Revision 10-26-2007 you need to put it in the microwave as that firmware version no longer supports cool temperature lithium regeneration, only heat generated lithium regeneration. Always read the instructions first.
**legal disclaimer** this post was sarcasm, no one should place any electronic device in the microwave or the freezer. Any action after reading this post is of your own choice and the person who made this post assumes no liability for any of these actions, including those that lack common sense.
For anyone who is reading this, OP is (obviously) not serious, and you should not buy a XIM1 in 2019.
