Picofly HWFLY clone help

[dehydrated_lemur]

EDIT: I think I got a dead chip. I replaced the whole thing without changing ANY resistors at all. Even RST still has one and it works now. I think I save the chip though. It may work on another switch.



Hello Im having issues with the emmc running in slow mode. OFW or CFW sysnand wont boot. Only Emunand. I replaced these resistors on the chip with 100ohm ones. The other 2 resistors that are blank are both 47ohm reisitors. The brown color coded resistor according to my multimeter is RST point. I even tried removing that resistor and bridging the pad because I know normally RST doesnt have a resistor. Any clues where I can go from here?

I'm having a similar problem. The red dot on mine is 200Ω, while the purple dot was a dead short. The brown and yellow are 47Ω resistors. Got to the point where my eMMC is corrupt and I'm also getting eMMC running in slow mode with errors.

Replace your resistors like the picture above, 100ohm on these 2 points.

I dont see the problem? Done it many times on these.

I tried and it didn't work. Same problem. I might just get another mod chip like dehydrated_lemur did and see if that fixes it.

100ohm 0805 right?

100ohm 0805 right?

No, for switch v1-2 picofly core chips it is 0402

I used the chip pictured above on a different switch and it worked great. Some switch's are more picky about the resistors. Also, you mentioned the red dot resistor. Confirm it's the same point as mine because these clones are all different. My red dot was point C but yours may not be.

I changed both resistors with 0402 100ohm ones but still get 2002-3540 error code. I just don`t get why it still wont work, do I have to change the other resistors too?

Hello Im having issues with the emmc

Hi is your EMMC skhynix?

Hi is your EMMC skhynix?

I have no clue. I got the switch working by replacing the chip. It's not my switch.
