J3SS3,

Sorry to hear that your F1G3 is beyond simple resurrection. I am in the same situation and the battle is ongoing with the less than honest seller in my case. Sadly a faulty F1G3 Pro is not worth much more than a faulty F1G2. I have paid between £35 and £80 for faulty F1G2 units over the years. They are a good source of a Lepton 3 core and this is likely why they retain at least some reasonable value even when dead and likely beyond repair.

Hey All,
Well my story is done.  I sold my F1PG3 on ebay and got about $150 for it!  I guess covid has somewhat affected the supply of lepton cores for projects (thermal drones, etc).  So I may have caught the market at the right time.  My new Seek Compact is clearly does not have the capabilities of the F1P, but it's sufficient for my meager residential needs (though I already miss the merged visible+infrared image).  Thanks again for the ideas to try for DIY repair.  Good luck and stay well!

Hello,

first of all thank you all for the huge guide and shared experiences with faulty Flir Ones. I bought a Flir One Gen2 iOS on ebay wich was sold as working. The camera charges fine and turns on (green flashing light). I replaced the battery since the old one was reported as weak and its still charging and turning on. I hear the lepton calibrating every once in a while.

When I open the Flir One app and connect the camera to my iPhone 7 i get the battery percentage displayed but no picture and then the app crashes. Sometimes the app does not chrash but i still only get a black screen.

I tried with other Iphones (unfortunately all the same model), but no luck. I also tried the reset method but everything stays the same.

Does the Flir One Gen 2 work with newer Iphones and the latest iOS 14? The newest Iphone reported on the packaging is Iphone 6. Did FLir just Sofftware limit the compatability?
Do you have any other tips for me, what I can try? Tanks!

Edit: I also reseated the lepton sensor but no luck
Edit2: Tried a 3rd party app that uses Flir One Camera. It also crahes when trying to connect to the camera

can it work normally using the old battery?

Does it work if the charger is plugged in while you connect to the phone?

Maybe try the plug in charger -> hold power for 2 minutes (set a timer as this feels like forever) -> while still plugged in press power again (green blinking should start) -> plug into phone.

It seems this has worked for me (sample size of 5 - 10 crashes, followed by above procedure working one time so far)

If this keeps working I guess I can power it off of a USB battery pack until I break it apart and replace the battery.

so i bought a F1G2, advertised as faulty
got it, symptom: orange light, with a short flicker after 10s like it want to boot, then remained orange
battery was flat, i charged it externally till full. tried again, same symptom
tried Fraser's reset method, unsuccesful

proceed with reballing Nand flash, same symptom.
proceed to reball processor, now the F1G2 boot up, green flash like it would do normally.can hear lepton shutter flickering.no charging LED when charging

however when i tried connecting the camera to my Iphone XS max, phone succesfully detected the camera and prompt to open with Flir One app, but it crashed the app as soon as the camera initiating(can hear shutter flickering).can only see battery level with black screen for maybe half a second before crashing.
tried with my old Iphone 5s with older version flir one app.same thing happen

now i had a spare lepton camera, tried changing the camera but same symptom, so i dont think Lepton is the problem
soldered a known good battery to rule out battery issue, same finding

any idea or solution?

I have read accounts of flash memory being corrupted by the high temperatures used for BGA rework. There is the possibility that you fixed the processor poor soldering but sadly corrupted the flash data as well :(

I avoid reworking the FLIR One camera dongles..... nothing but heartache on that path  :(
The FLIR One series of dongles are, without doubt, the lowest quality, highest failure rate, product that FLIR have ever produced :( The reason..... FLIR wanted the cheapest possible manufacturing cost so outsourced the work to a sub contractor in China. They dropped the ball on the quality control and testing fronts.

Guys, and who has not tried to run the Flir One Pro Gen3 without a battery?
First, supply power to Type-C and connect to a smartphone without a battery.
If everything is OK, then you can make one connection internally between the Type-C charger and micro-USB / Type-C data.
Alteration will make a siktermal out of flir :)
I haven't used flirting for about a year and the battery has completely run out. Now the flir cannot even charge the built-in battery to 100% - the green LED does not stop blinking for 6 hours, and then the orange one turns on. Nevertheless, there is still 10-20 percent of the previous capacity in the battery. And the thermal imager does not work for long.
The question is in the vandal-free analysis of the subject.
Is there a parsing order in pictures or videos?

Good morning all,
I have been reading you for a few years and own a flir one gen 2 for over 2 years. It worked well until recently ...
But suddenly, I got the famous fixed orange light ... The camera does not start anymore and the orange light turn off only if I press the button for at least ten seconds ...
I checked the power supplies, everything is ok, I will now unsolder the microcontroller to reball it. If that does not solve the problem, i will do the same for the memory. For now i'm waiting for some tools and will learn to use those correctly before doing this delicate operation on the real device, As you can see, i was able to make an x-ray view of the board.

I did a data acquisition of the start-up sequence with putty by connecting a serial to usb interface to the card on the dedicated pins. Here is what I get:

The camera constantly reboots ...
Can I deduce from these few lines if the nand flash is ok?

RomBOOT
Start AT91Bootstrap version svn-r5344 ...
Init HALF drive strength DDR... BOARD_ConfigureDdram()
DDRSDRC->DDRSDRC_LPR: 0x12101
Done!
Downloading image...
Trying to load uboot...
nandflash_hw_init()
reset_nandflash()
AT91F_NandReadID()
ManufacturerID: 0x2c DeviceID: 0xa1
chip id: 0x2ca1
Copy 0x50000 bytes from 0x40000 to 0x23f00000

switch(sNandInfo.uDataNbBytes) 2048:
read_nandflash: while (1)
read_nandflash: while (1)
read_nandflash: while (1)
read_nandflash(): return 0;
Done!
Returning jump to 0x0x23f00000
After 10s ----------------------------------------> restart line 1 (Romboot)
