Can't unbrick yi?

[agour]

Hi all,

I was trying to downgrade my camera from z25 to an earlier version.

During trying to upgrade, the camera got bricked. When you turn it on, only the top and rear LED lights show up. Nothing else happens, no noises, flashing etc.

I finally managed to downgrade my camera to z22, using the tool

Found 1 YDXJ device!
Init DRAM ok.

From what I can tell, that worked properly?

BUT, the camera is still displaying the same symptoms as before.

Any ideas of how to fix it?

Thanks!
