Please help me.

First of all, I didn't know before that there was different version of it and went straight to changing it to the US version.

What I do is below :

1> I tried to reformat the SDCard, add the US SN.txt, add the engmode, add the AAA222CCC.txt

2> I tried to reformat the SDCard and tried with FWCARC10.bin only. the yellow light doesn't blink.

3> I closed everything and I tried to open it. I got the Pink Screen.

4> I tried to reformat the SDCard and tried with FWCARC12.bin only. Nothing, the yellow light doesn't blink.

FWCARC12.bin from http://www.xiaoyi.com/yi_dash_camera/download.html


I think my CC version had a US S/N still.

How I can re-cahnge US s/N to Original CN S/N ?

or Do you have a special method for re-make FWCARC12.bin with US S/N ?

Please help me.

JUST DOWNLOAD THE ENGLISH VERSION (FWCARC12.bin)
and done! mine working well

@IcyGBait
Read thru thread below link... Got one post stated create 2 files and put into sdcard, it fixed mine as I noticed my ca31 unit sn being messed up by seller... So I use put the actual sn no from bottom of the unit below the qr code into sn.txt and another file AAA222CCC.txt into root of your ad card... Reboot your device and wait... If a blue screen pop up with the sn no you put in then it should be working now.. else hit reset!

Old check your SN as it is same with your unit? Mine one being tempered by seller causing this... And I mange to get my unit running again with putting the actual sn of my unit.
