Hi,
I have a SJ4000 since 3 or 4 years. I d'ont have the package but i'm sure is an official one.
2 days ago i tried to upgrade firmware with a latest one. Now, i know it's impossible...
After this try i only have yellow light on top when i put on the cam, and blue light but black screen and no noise. I never have something on the screen. When i plug it i hace red ligth too.
Yesterday i found previous firmware from here
I try all firmware (wifi 1.5") but just after my first attempt the blue light was disappear !!!!
Now i juste have yellow light on the top when i switch on the cam. If i plug it i have the red light.
I try 3 sdcard in FAT32
I try with or without battery
So i'm desperate. My son want it now because he had a scooter...
Can you help me ?

thanks
