Hello Guys.
I've also bought a broken Flir one gen 2 (first one attached to the phone). After reading the post about resetting the module I thought it will be a straight forward but not exacly...
The symptom were in my case:
- orange LED always on (red and green bought lighten up)
- after holding the button for about 10s the orange light is going down, but after releasing the button it light buck up
- i saw a green light briefly go down for a split of the second after connecting the battery
- charg led is not lighting and the battery was not charged
- cam was not detectable by the phone
I've charged the battery externally. The reset procedure didn't work for me.
After reading the post bout reballing I've decide to give a shot to reheat the chips, so I've poured some flux on flash and man CPU, and reheated them with hotair. Of course I know it would not be permanent, but I deducted that the units were testes in factory, so a cold joints are pretty probable (especially since my unit was factory new condition) , and reheating could work, and it did work to some degree...
Now the camera is more alive:
- after pressing button the light goes orange, and then green is flashing (around 1s period)
- the camera is detectable by the phone, It reads the battery percentage, but no image from any camera
- the charging light is still not lighting
- if i turn it on (the green light flashes) and not connect it to the phone it truns off after some time.
Questions:
1. What would You recommend to do next?
2. Green flash meaning its booting, it should be solid after it boots properly?
3. Is there a serial UART somewhere on the board like in the case of Flir One Case (for iphone 5) like Mike showed in his video?
4. When raballing can You confirm is it a CPU and not Flash? Resitting both is 2x more risky. I've never did any reballing... Watch a ton of YT videos... but still not confident
Is it easier when reball the chip with bought balls (not stencil)?
5. Maybe somebody have a tested working open hardware project for breakout board for Lepton, possibly if it straight forward to use/test it?
Thanks in advance for any advice.
===============EDIT===================
I've also verified that the battery is charging now - it draws around 500ma, but the charge led is off. I don't see any move on the shutter at any point.
