Hi Sifus,
Need help.
I have Yi Dash Cam (CA21W) model.
It is already on the latest firmware Chinese version V-1.03.026-CN.
Me and my itchy hand went and try to change it to international language version.
I followed the below steps.
rename my first 14 digit S/N from CN > US, save it to SN.txt
then create a file engmode.
formatted my micro sd (via yi dashcam)
then transferred the files over to the micro sd(using Micro SD adapter n transfer via laptop)
then i insert the micro sd then only connect the power.
then a blue screen showing Firmware change, nothing happen.
then waited it rebooted the device.
i dont get any engineering mode as claimed.
shit happens here whereby i get error stating "System adaptation failed, Access Denied" but in Chinese.
so i go download the latest FWCARC10.bin from the yi technology website.
so i copied over the FWCAR10.bin to micro sd.
but still cannot flash it as it keeps starting up the dash cam and stuck at that error message.
Any help is highly appreciated.
Thank you.
Um... Sounds like your Yi dashcam has bricked during the flashing process...
