When pulling out the ROT66G2 dirver (after all the experiments mentioned before), I damaged some components accidentally, and now the MCU is not responding even with a programming clip. So now I cannot be sure if the programming holes are already defective by its design or mine is simply a defective unit. But how come I’m not able to program LT1 with its programming holes either? No, I don’t like to pull out the LT1 driver, in case it can get damaged as my ROT66G2 too…
And that’s also why I post here — I’m curious if someone else, who also has a LT1 or ROT66G2 production unit and the Lexel programming key, may have encountered a similar issue. I would like to have more ROT66G2 / LT1, but I must confirm if this is a common situation first.
That’s strange, because the same key works for me on PL47G2, E01, ROT66G2, and LT1. Also on some Mateminco lights, and PL47 original. For the FF E07 it works only if I disconnect the aux LEDs first.
I’ve only needed three adapters to flash things so far:
SOIC8 clip
Emisar pogo pin adapter
Lexel’s pogo pin adapter
The HQ Progkey can do either of the pogo pin layouts, but needs a couple wires moved… so I keep two different ones in order to avoid switching it all the time.
I finally had to recharge my LT1, after plenty of use. I enjoyed finally seeing the various LED colours for myself.
However, since charging, when the lantern is off, it is doing a strange two-level flash with the orange LED in the button: off, low, off, high. I can’t find any reference to what this means. Battcheck says 4.2v. is there something I overlooked?
Have you done a 7x click? On Ardúril lights with AUX LEDs, this changes the LEDs from low > high > beacon > off, and it also affects the switch backlight.
not sure why this would have changed from before charging, but if you press the on-off switch 7 times, starting with the LT1 from the off position, the behavior of the switch LED will change to next off, 7 clicks again will make the backlight low, 7 more clicks to the backlight on high, then 7 more clicks to the state you described above.
Looks like I came in 2nd place here . . . :person_facepalming:
Thank you both for your help. I have not clicked it seven times, however I can easily imagine my son doing exactly that. Thanks for the lightning fast responses!
I got a code from Sofirn on Nov 21, I bought one on or near that day, it shipped out (reached China Post) 12/5, and is in route. I believe this would be the 2nd batch, but not 100% sure. the message I got from Sofirn with my code was
Since I bought my first lantern in October, I’m guessing this is batch 2.
I held back so someone with more desire to get one before Christmas would have a better chance. Then I decided I’d waited enough.
My Amazon order on Dec 3 says it shipped Dec 4, and to expect delivery between Jan 9 and Feb 5. As of today, Neither Amazon nor 17 Track have any information on my order. I hope to see some movement data by the end of the week, but I’m not holding my breath.
Tracking won’t update, it will show up at your address some random day, and tracking will still never update. I’m sure it’s in transit.
I think the wait for the small resistors I ordered will take longer to arrive than my light did. Hopefully before end of month. I’ve been waiting for 3-weeks on that with no track-able status. Already received two sizes of enamel wire from China via eBay, for the usb-c cable charging mod posted earlier.
