Hacking Hardware Instinct-NX V6 booting issues

Teo338 · Jun 29, 2024

Hi guys
I soldered my Instinct V6 today in my switch OLED. Sadly, when booting, it gets the following LED-Pattern:
Training LED (just blinking Yellow) - Blinking Purple for a long time - Flashing Blue LED multiple Times (more than 3 times!!!) - Boots into OFW
I couldn't find any problem description for this pattern.... I also checked over USB the diagnostics and it said at the end, when the Blue LED flashes "RST Failure"

This are the Point values I measured in diode mode:
A - 0.585
B - >= 1 (my multimeter is a cheap one from china and can't display more than 1)
C - 0.745
D - 0.507
3.3 - 0.862
SP1 - 0.013
SP2 - 0.013

As far as I know, those values are correct (if I'm not wrong).

I can't see any problem... Maybe I'm stupid, but do you have any solutions?

Right now, i get also the problem that at the end, the LED flashes RED and the diagnostics says "Exhausted all options" (See attachment)
Maybe there is a connection between those two errors...

These error codes match your color codes :

So that would mean SP1/SP2 disconnected.
Is the flat cable inserted correctly / far enough?
Also maybe check for continuity on the flat cable to see whether there is no crack in it.
There are some pictures floating around here that show the layout of the flat cable.

It isn't a LED pattern on that list. At the end, it doesn't blink blue three times, it blinks more than three times. I also checked it: when i disconnect the flex cable, I get the three blinking blue pattern. Also, the error message wouldn't be "RST Failure" when it blinks three times (something with "Flex cable" would come up)

I got now a video of the problem with the blue light

So, I fixed it.
For anybody who wants to know how:
The solder on the SP1 and SP2 capacitor were not well. I soldered it stupid and accidently fucked it a little bit up. When i measured it, I got somehow 0.020 (diode mode) on both. I heard 0.014 was perfect, but I don't know if 0.020 is also "Ok". I also asked sthetix and he said I should check every point reversed (red on ground, black on point). I should got something about 0.400V and they were fine. Also replacing the chip didn't work. I also pressed down and moved the flex cable for the capacitors and tried to train the chip. On a perfect position, the LED started to blink also green with the yellow one (which means it is trying something to train or got successful). When I found out, in which position the chip worked, I hold it then and glued it down (soldering it new wasn't a option for me, because I already fucked the capacitors up, my luck that it still had a connection.). After the glue has dried, I tried it again and it has started in CFW and hadn't got any problems (yet). I actually need to wait sometimes up to 2 minutes until it glitches, but I think it is because I fucked the connection to the capacitors up.
