So using the cables set:
https://www.aliexpress.com/item/1005003707742673.html?spm=a2g0o.productlist.0.0.4900bc41q0puSp&algo_pvid=9c23c7a2-e4a8-42e1-9305-3158d72238ff&algo_exp_id=9c23c7a2-e4a8-42e1-9305-3158d72238ff-7&pdp_ext_f={"sku_id":"12000026880523305"}&pdp_pi=-1;20.85;-1;[email protected];AUD;search-mainSearch

There is now 2 solder points on the OLED Board (Excluding the solder points for the the CPU cable) and 1 solder point on the SX/HYFLY chip board for the 3.3v.

Hoping the 3.3v can be added to the cable or something so make soldering easier.

Hey had a quick question. Got the Hwfly lite installed on OLED, however it flashes purple/blue then red then off. I am only testing using USB-C power, not in the case, not using power button. I am assuming the problem is the switch isn’t booting, just trying to charge. In all the videos I see they test in the case. Can anyone confirm this? Just want to make sure it’s not a short and it’s just how I am testing. Thanks

Usually dat0 adapter for red light

You cannot flash the new ones with default spacecraft. They contain a modified Spacecraft. This is to account for the new FPGA and the pin definitions and such. Flashing it would result in infinite glitching or nothing at all. I wouldn't even try it.
is it bad?

In what sense? Bad they modified it? No. Bad that they modified it without releasing the source because they're in violation of the license? Yes. If you're referring to reflashing it in hopes it would "just werk" then yeah it's bad. It'd never work until Balika looks at it

Let's compare the pinouts from the mcu's. If they indeed changed stuff, we can find out. Then we should look at the communication between mcu and fpga to see if this fully matches spacecraft. If so we can modify spacecraft to match it, should be simple enough. Then we can transplant a new mcu with actual spacecraft firmware onto hwfly boards.

Sorry for not being specific. Never actually dealt with the modchips. I know that SX chips are rewritable - firmware update option was possible. What about the OLED new chip? It is still HWFLY, but is it updatable in terms of being rewritable? Also, is there any downgrade in performance vs original SX chips? I'm bit confused about the spacecraft versions too. The new chip for OLED comes with modified version of the original spacecraft or the release 0.2 for OLED models? Besides the pinout modifications in spacecraft, are there any other benefits or downsides? Thanks for your time! :)

So the light on the chip should go green even if the board isn’t installed in the case? My theory is that since the switch wasn’t “booting”, just charging that the chip tries to boot hence the blue/purple light, then red because nothing to attack, then off since the switch is just charging. I will let you know for sure once I can get in back and in the case

Technically, yes it's rewriteable (someone tried to write spacecraft 2nd release to it) and it won't glitch fully because the original spacecraft that was on their was a modified version. The OLED chip is HWFLY. No there isn't a downgrade in terms of performance. It comes with a modified version of the 2nd release of spacecraft. Lastly, no there aren't any benefits honestly. It was just a better form factor for the OLED.

Other new chip for oled switch on sale:

Green Joy-Con D-Pad Shells for Nintendo Switch
This one is much better thought out than the current "OLED" specific one

Yes it should. It will show black screen if you don't have the SD inserted, but red certainly points to an installation issue.

Hmm, haven't tried that. But I think it might require the screen too.
That’s what I am thinking, the Hwfly should fail if no dat0 emmc data, and I don’t think the emmc would boot if the switch is off in charging mode. Otherwise the chip would be on all the time
