Hacking Hardware Picofly - a HWFLY switch modchip

[juanvlc]

update has a protection, it completes only on a successful boot. so just power it on again to launch the previous firmware.

oh there was one change that could bypass that

Opened and flashed tru usb: same result as before. Blue then pink then ofw boots

In the same spirit, I vectorized your graphic. The attached is a scalable vector that can be used to make icons, large graphics, and other things without losing fidelity of the shape. Just download and remove the .pdf extension to use in your favorite photo editors.

WOOOOOOOW thanks didnt know that Xd

looks way better now

Did you change LED codes in the latest firmware or something? I am getting a blue, then red, then get hekate. Everything still seems to function with the latest update for me on a patched V1, just the LED has changed.

EDIT:
I rolled back to 2.61 using the toolbox, and regained the green success LED, with still no functional issues with booting to hekate or into OFW or others. Only the LED seems to have changed for me on 2.63. I like the green for success, so I'll stay on 2.61 for now. No issues with it anyway.

the rgb mode switch detection code was changed, thanks, I check it again

(it either doesn't work now, or finally detects your chip as it should be)

To clarify, I am one of the rp2040-zero users that needed to jumper the RGB pads to get the correct colors.

Lol, now I think the firmwares are missing from your firmware post, unless you just haven't gotten the chance to recompile and update them yet. No worries

Can confirm, running 2.64 after flashing through toolbox and all is well again. Thank you for your hard work Rehius

Fortunately, I had left the USB port attached during the installation process, so flashing FW2.64 was a breeze. After doing so, the LED color change that previously went from blue to purple with FW2.62 now goes from blue to green, and I'm once again able to enter hekate! Great job on the FW development!

Here's another quick little edit I did of the picofly logo we've been messing with.

Wait of course since the cable hasn't been arrived.

I already flashed the 2.61. can i just flash 2.5 and unlock. Or do i have to factory reset the rp2040?

I remembered the update.bin is introduced on 2.6. I think to downgrade 2.5 you need to flash it and unlock using usb.

you can, but 2.5 has no software update feature.

it's better to upgrade to 2.64

 

[Cait_Sith]

I already flashed the 2.61 how can i remove it from the rp2040? so that i can flash the 2.5fw then unlock or maybe when a newer version arrive.

no need to remove, you can flash any firmware over another one

Why you want to flash v2.5?

To be clear, YOU DO NOT NEED 2.5 FIRMWARE. It is the only version of the firmware that does not come unlocked ahead of time. There should be no issue with immediately flashing 2.64 to your device.
