OK, Patient resuscitated and healthy  :)

The LiPo cell was charged and refitted in the camera. The camera only illuminated the Orange power button LED and could not be shut down.
The camera appeared to be in a permanent 'on' state but not booting. This would explain the fact that when connected to the USB charger the power LED lit ORANGE and stayed on.

In order to reset the camera to its correct stand-by state and normal operation I carried out the following reset routine after some experimentation

1. Disconnect the LiPo cell from the PCB
2. Connect the USB charging cable. The Orange Power button LED will light
3. Press and hold the Power button until the Power button LED extinguishes - forced shut-down (If you release the button it will go back to solid Orange again. i.e. no change in state)
4. Whilst still holding the Power button in, disconnect the USB charging lead, then release the Power button
5. Reconnect the LiPo battery. The Power LED will light Orange.
6. Press the Power button. The Power LED will start to flash green and the camera will boot normally
7. Press the Power button to switch off the camera
8. Push the Power button and the camera will boot normally.

The camera is now working normally. It appears that these cameras have somewhat flaky firmware that can get locked into a permanent semi-standby state that will flatten the battery completely (to the cameras 3.0V cut-off point). The only way to recover the firmware to a state that works is to carry out the a full system reset as detailed above. This erased the registers and sets the camera to its factory default conditions. From that point onwards it can boot normally.

I seem to recall that FLIR provided some similar instructions to factory Reset the old FLIR ONE Gen1 for iOS. They told people to let the battery go completely flat before a power on reset sequence. I forget the details but my experimentation came up with an equivalent for the F1G2.

Hope this helps others.

I just found the reset instructions for the Flir One Gen1....

https://www.eevblog.com/forum/repair/flir-one-personal-infrared-camera-for-iphone5-no-green-light-blinking/msg616240/#msg616240

Different to the F1G2 as there is no reset button and the process is different to my procedure. Why the FLIR ONE G1 needs to have its battery flattened AFTER pressing the reset button is a mystery to me.

I forgot to mention, after the battery was charged and camera reset, the green LED 'charging' indicator started operating again. it could well be that the battery was so discharged that the F1G2 charging circuit would not start.

Greetings to you, friends. So I had the same problem. I'll tell you everything from the beginning ...

First time, i connect it with my phone, install official software from google market. Flir will work correctly. I take 2 pictures, it's ok, and i desided to disconnect flir for charging.

I connect charger and wait. When it fully charged i try to power on device, but orange led isn't change color to green and not change color. Flir isn't power on correctly now, phone cann't see him, and flir have no reaction to connecting charger to him (not blinking led near USB).

If connect charger thru USB ampere-meter and to device, that shows, that no current, but if i press power button about 15 seconds, button light goes out, and if kept pressed this button connect USB charger, then accumulator start charging (ampere-meter shows current about 650mA and under as the battery is charging). But if i release power button, she start light by orange color and nothing happens.

Solved the problem by disconnecting and attaching again the battery. It worked correctly with the phone, but by connecting the device to another phone the orange LED lighted up again and I returned to the same problem, but I could not solve it by the same method. The above recommendations do not help either. Symptoms are the same as for the first time.

What else can be done? I can measure voltage anywhere, resistance, if it need. Help me please, guys.

My first question would be, is the unit new and purchased from a FLIR agent ? If so, return it for a replacement as that will ensure long term reliability.

I shall have to test the latest repaired unit on other phones and see if it remains stable.

I have been asked to look at 14 of these cameras that are all faulty. I have yet to decide whether they are worth my time and effort as I cannot charge much per unit for the repair. I suspect that there is either a duff batch of cameras or a flaky firmware in the 'wild'.

No, it's not from a FLIR agent.

I had this silly battery problem happen to me (I bought one at launch). In fact my unit did not work brand new out of the box.

So, I took it apart as I had planned to anyway, and in the process replugging the battery.
The unit worked fine afterwards.
Seems to be a weak point as well as the firmware.

I am tempted to solder the battery wires to the PCB socket, but that makes it less convenient to do a 'Hard' reset if required. As previously stated, the battery connector is a pretty poor type that can easily suffer intermittent contacts.

What can I do in my case? Can I test the operation of individual modules, for example Lepton 3?
Almost about 2 weeks he is in this state, and I do not know what can i do.  :(

It is unlikely to be a LEPTON3 fault. Have you ensured that it is correctly seated in its socket as Bill W has found issues with this. The power management IC is also worth checking for correct operation.

Sadly beyond these basic checks you are pretty much stuck with a dead unit. They are not exactly repairer friendly unless you are equipped with appropriate hot air rework equipment. If the firmware is at fault, no amount of hardware diagnostics will help.

I am sorry that it is not better news. I am still finding my way around these highly integrated cameras so cannot offer anything more useful at the moment.

LEPTON 3 is normal sitting in his socket. All ICs have a stable voltage. Seat of LEPTON 3 have all three voltage variants, that declared in datasheet. MAX31725 also have a normal voltage, that declared in datasheet. I have a gas soldering-iron (have a nozzles for warming up), who was helps me once to reboil a microchip on the phone after falling to the floor, but i think it can't help me in this case and i'm afraid to use it there.

Two FLIR ONE G2 iOS versions are now on their way to me.

Two more patients to examine. Hopefully they will work with my IPod Touch 5.

More news when I have some.

The two IOS versions have arrived. No time at the moment to investigate their failures. More from me when time permits.

Hello everybody,
I write from Italy and I found some possible solutions only on this forum;
I bought a F1G2 for Android from a private ( |O) and when I received it and plugged to the USB connection, I realized the orange led stayed lighted on.
I tried to disconnect the battery, connected the USB charging cable (and the orange power button led lighted), pressed and held the power button (the led extinguished), while still holding the power button I disconnected the USB charging cable, then released the power button.
Then I reconnected the battery, but the led DIDN'T light. Nor it did pressing the power button.
It just lights up when I plug the USB charging cable, that's it.
Any suggestions?
Thank you all
greetings

Can you measure the voltage on the battery?

I will do it today.
The matter is, when it is connected to the device without battery, it doesn't work either.

I have a problem with my Flir too. Is your problem similar with my: https://www.eevblog.com/forum/thermal-imaging/flir-one-gen2-failure-investigation-by-fraser/msg1172399/#msg1172399?

It happens that the battery goes into protection and shows 0 volts and is not charging in a regular way. You can "Wake up" the battery by fed to it from 3.7 to 4.2 volts (for example, from the battery 18650, connecting + to + and - to - for a few seconds). After that battery have to show normal voltage.

There is an simpler way, if the voltage is 0: when the battery is connected, connect the USB charging, hold the power button until the orange diode goes out and hold it for about 30 seconds after diod is extinguished, because during this hold, the battery begins to charge.

It looks like you have the same problem as me, but I can not find a solution for almost a month. :( "Flir support" also can not give me more powerful technical support.
My Flir is recognized by PC as a "Flir COM port", it seems that i can flash firmware, but no answer from "Flir Support", how to do it.

Good grief! So it should be a firmware problem?

I think that this is the firmware, as I checked all main chips, output and input voltages and found no deviations from the declared in their technical documentation (datasheets).
I have no other solutions so far. (

I concur that there appears to be a firmware vulnerability that leads to the described behaviour. Sadly, unlike the E4, I have not seen new firmware versions that may be loaded into the F1G2. I would have expected the FLIR One APP to offer firmware upgrade as an option. It may even be automatic.

Unfortunately, not one phone can see my Flir, since it does not go into power-on mode (green led does not light up)
