Hi everyone, 


I have this new Lemfo Lem P 1gb + 16gb and I’ve not been able to start up the watch since I got it. The watch is stuck on the lemfo logo screen whenever I plug the watch to charge. As long as the watch is plugged to charge, the lemfo logo screen keeps going on and off until I remove the charger. Sometimes it shows the green battery icon moving up to show that it is charging but goes off whenever i remove the charger. The power button only works when the watch is plugged but does not respond when charger is disconnected. I also hear the PC USB connect sound and the disconnect sound after few seconds but no access to the storage whenever I plug it to my PC.  

I have installed the drivers especially Spreadtrum SCI Usb2Serial on windows 7 as I was unable to disable driver signature enforcement on my version of windows 10. After installing the USD2Serial driver, I connected the USB cable to the watch, plugged cable to my PC and the PC recognized the watch and installed the device in device manager.
However, the device manager keeps refreshing. Once I connect USB cable to the watch, then press and hold the top button on the watch and connect the other end of the usb cable to my PC - while watch is still powered off, the device manager displays the device but keeps refreshing which seems to be a pointer to the fact that the device connection to the PC is intermittent.

I want to flash the device. Can I still go ahead and initiate the flash while the device manager refresh is still happening?

I keep getting this error : failed - write flash failed. Even when I tried flashing one by one, I observe that I get write flash failed error for all the .img and .bin files including NV_WLTE, ProdNV, PhaseCheck, VBMETA etc Is there anyway to enable write permission on the device memory?
