IT'S BACK!!!!!!!!!!!!!!!
With my eyes full of tears I have to inform the whole community that my lil device is back!... Still with blank screen but ALIVE!!!!!!!!!!
That of the USB port was a false alarm... so don't panic... was just this damn RAMOS firmware requires some tricks to get USB connected. I've read in some pages that Ramos user claims that their devices don't show itself in the USB icon.
I keep trying short circuit until I finally get the loved rockusb icon in my PC. Then I installed the firmware sent by the manufacturer (in the wrong version) and i have my pendrive back showing its blank face.
This proves 3 things:
a. Ramos devices are very strange. This is the second time I get into problem trying their firmware... first was bad blocks issue.
b. Rockchip device are extremely consistent... which means that you can load any firmware the processor will work accordingly you just will act "blind folded"
c. Sooner or later short circuit strategy will recover your rockchip device... I've done at least 50 times before i get the upgrade connection.
So here I am with my 2.2" 224x176 device ready for continue trying other firmwares that the damn manufacturer is not capable to send me.
That company is named LDX or LIDAXUN for the device LD-696.
