If you have a pair of rubber gloves lying around, that might give you a bit of extra grip. Otherwise, you could try a pair of strap wrenches, although you might be just as well buying a new light for the cost of the strap wrenches and the spare parts.
Rubber gloves made the job! That was I great idea! Thanks a lot Phlogiston! Cheers!
Excellent! I’m glad it worked 
We have an A6 each and are waiting on the tools mentioned in this thread Guide: how to flash ATtiny13a based drivers (NANJG, QLITE, etc.) with custom firmware to arrive… But my question is this what else can we do with regards to modding/flashing the firmware? what othe firmwares are there?? I have the the 11mode(think its that) and partner has the 7/4 mode firmware… Could we flash the 11 mode version on her A6? if so where do I get it etc?
looking forward to pushing the A6 further
regards
Lohtse

Already watch/reading them…but a lot to go through so was hoping for quick answers to point me in the right directions
The INDEX file has a list of firmware projects sorted by various criteria. I’d suggest looking for projects which list support for dual PWM, attiny13, and clicky switches.
ok and thank you….Can i flash the 11 mode firmware on partners A6 is so which is it?
I don’t even know what the 11-mode firmware is. It doesn’t sound familiar, unless “11” means “7+4”.
On mine, I run something a little different… cypreus2. It’s similar to blf-a6 in the 7-level mode, with no memory and no config options. But in the hidden blinkies, it has a lot more modes:
(the current version is rearranged a little, but this shows the general idea)
I believe you once mentioned that ( Code now public! BLF A6 FET+7135 Light. Short 18350 tubes and Unanodized Lights Available - #6194 by ToyKeeper) that I had Bistro flashed on mine when I one asked why it didn’t match the advertise setup… Where as my partners had the stock/first firmware… SO does that mean I can flash the bistro firmware? and s the currrent one in the index same as the one flashed on mine?
It has been a while. However, if there is a question about what type of MCU is on the driver, you should probably look at the chip to find out. It should be either tiny13 (blf-a6) or tiny25 (bistro).
Or it should be pretty clear which is which any time you turn it on at a medium level. BLF-A6 lights up at the target level immediately, while Bistro has a soft start effect which glides from zero to the target level over about a third or a quarter of a second. Or you could tell by entering config mode. BLF-A6 blinks twice, pauses, blinks twice, pauses, then exits. However, Bistro has a much longer config menu.
I know that my partners is the original BLF A6…and on spring side says a17dd_l and blf,
thank you for answering my questions and your patience…
You MUST read the actual tattoo on the 8-pin chip. Either chip can be on that same driver board and trying to flash the wrong file can lock the driver up.
She’s trying to help you out, telling her what the DRIVER says doesn’t answer the question she asked in order to better answer your questions. It’s like you’re not reading her posts, just the first line of each…
ok so how do I get to it??? I have unscrewed the brass rig but can’t seem to get further! without desoldering Both blfs look to have the SAME driver and looks like this one Page Not Found - Aliexpress.com my firmware is def Bistr and partners is def BLFa6 Ui
I’m wondering, the driver on my Astrolux S41S (quad-Nichia 219B or 219C) seems to be malfunctioning (Moon mode doesn’t light up, the 2nd and 3rd brightness mode are exactly the same brightness). I notice the Astrolux S41S uses the exact same user interface as the Astrolux S1 (BLF A6).
Would it be OK to just buy a BLF A6 firmware driver (the one from Banggood) to replace the malfunctioning driver on the Astrolux S41S? Or is it a different driver that’s designed for quad-LEDs?
Yes, that should work fine. It is the same part that Astrolux uses.
After a month, my most recent BLF A6 started rattling when shaken because the lens is loose and taps the sides of its housing. It’s tightened down as much as it will go.
Any suggestions on a fix would be appreciated.
Do you have a spare O-ring to put between the lens and the bezel?
That worked. Thank you!
Although my other A6 does not rattle, I’m going to do the same thing to it to prevent debris from getting under the lens.
You’re welcome
BLF A6 / Astrolux S1 quality control is very flaky, hence the variation. I have an A6 whose bezel only screws down properly if the O-ring is between the lens and the reflector (which compromises the water resistance).
I need to experiment with some spare parts to see if I can fix that. Alternatively, I might transplant the LED and driver to a Convoy S2+ host I have lying about.
