Switch OLED teardown V1/V2

[Excitedguy]

I installed the modchip (hwfly lite) using sthetix video guide and after connecting everything back to the motherboard, the switch nor the modchip turns on. I'm not exactly sure why I'm not getting any power, I double checked connections and they seem ok. I went ahead and read the diode values on all the points on the modchip and below are the results. Let me know if any of them seem off that could be causing my issue.

DAT0 = 0.685
CMD= 0.716
CLK= 0.721
RST = 2.913
CPU I = 0.023
CPU II = 0.552
GND = 0.001
3.3v = 0.002

I should also mention I did test the usb connection on the modchip to my computer and the green light does turn on, so the modchip itself should be good.

usually if its not turning on its related to a short somewhere on cpu solder points

This is the result of a v1 spacecraft hwfly chip. It sets some pins to 5v that shouldn’t be 5v on an OLED.

See above

Can confirm. I very probably lost an OLED to this. Spread the word. We really need a way to distinguish old and new hwfly stock.

 

[fennectech]

At least hes gonna replace my oled that got zapped by the chip.

Is there any way to tell if it’s v1 or not? Maybe by plugging it in usb and using a program?

Or is there a way to make the v1 work on OLED models?

I hear a faint buzzing sound when I turn it on with everything connected.

Not that I can think of without dead bugging the emmc.

What you mean by dead bugging ?

 

[doom95]

Taking it off the board and soldering wires from the underside of the BGA to some external reader.


I did notice a difference between two boards I have. The first one has a trace going from the left resistor pad to the bottom-left pin of the ic. On the second HWFLY PCB this trace runs to the bottom-middle pin of the same IC. So it appears the out-of-place looking resistor is a fix for a design error with the board.
That said, I'm unsure which revision either is, but it'd make sense for the second one to be a higher revision where the board issue from the previous revision was fixed. No guarantees though. If anyone has a known-good v3 they could confirm.

Dead bugging is when you flip the IC over and solderwires. It is very painful on BGA parts

I was thinking of ordering this cable set for the installation to make it easier.

Not too expensive.

But i wanted to know where the solder small cable go.

The small cable is for your NAND header on the lite. From left to right via the image of it, the order is DAT0, CMD, CLK, RST

Thanks for the explanation.

I have installed both of these hwfly lite on oled. And both boot without any issue so far. Will test it for 5 days or so.

Hey all, been following along here, and after inquiring with a seller on ali about the OLED version they were selling, due to it being cheaper as mentioned, was told new stock was arriving and they sent this picture which I haven't seen elsewhere yet (at least with all 3 in one shot). Just thought I'd share it. It also shows the new smaller DAT0 adapter.

I'll be watching for someone to guinea pig this new OLED version out and let us know how it goes, hopefully with a video. Maybe we can flash these ones? Looking forward to any news on these.

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.

Can you link this item?

For those that installed an original SX lite chip in an OLED, did you have to flash or mess with anything on the chip itself in order for it to function correctly? (Regarding correct battery read and switch hardware functions like sleep/power off/reboot)

Or once all wired in place, the switch was g2g and the SD card setup w latest hekate/atmosphere and such was all that was needed?

Just make sure to flash spacecraft 2nd release 0.2.0 and you're good to go with an sd card setup

I thought flashing spacecraft was only for hwfly/clone chips? And can that be done post solder and assembly or needs to be done prior?

 

[doom95]

Other way around, we can't reflash hwfly chips like we can the sx's.
