Hi Guys . I follow the steps to change to an English language , but I used my macbook for this so after a while , I manage to brick the dashcam. So first I upload the files engmode sn.txt and aaa222ccc.txt , and the blue screen pops up but I have noticed that on the serial number box says something like "*(&^%TUYG*&*(U " probably because of my Mac ,now after trying to reset 10 times and few time an emergency recovery , the cam still shows pink screen and Failed to addopt language. Im hopeless I don`t have an idea what to do next. I`ve tried many different fw chinese english and emergency , but still the same.

Newer version (CABAAA v2.1 in my case) need 3 files to enter engineering mode: SN.txt, engmode, and AAA222CCC.txt.

Make sure SN.txt single line only without whitespace, Windows EOL, ANSI encoding (default Notepad's text format).

Guide https://dashcamtalk.com/forum/threa...-yi-dash-camera-version-cabaa-or-ca31a.26533/ should be working for you but don't forget to format your SD card in step 11.

Hello,

I have a CA31A dash camera and I wanted to change to English. During the process I did a really dumb thing, instead of writing the first 14 letter of the serial number in the SN.txt file, I wrote the last 14... Now, if I add the correct firmware, it got stuck to the YI pink logo. I have tried many other versions of firmware including emergency aid firmware from the official website. If I try the emergency aid the camera got stuck with the "System language adaption fail. Access denied". Any hints are welcome.

Thank in advance,
Darius

If your camera is this black color version,if yes,please contact seller for help to reboot it with previous firmware!
