Hacking Hardware Picofly - a HWFLY switch modchip

[rehius]

Hello. I smoothly installed Picofly on a Lite. All is fine. Blue then green light with the forbidden fruit's no sd card logo. However, When I insert an SD card loaded with Hekate I get a black screen, it does not boot into Hekate. The SD card is working fine on OLED and inserting an empty SD card shows "failed to boot payload" I'm assuming both the SD card and slot are working, not sure what's the issue.

I had similar behaviour on Lite with damaged power regulator. Also ensure your battery is charged

Apologies in advance, but is there a diagram of the install on a Lite?
Traversing this thread is really difficult, as most troubleshooting questions are interspersed with images that I can't really understand.
Are there diagrams anywhere?

Thank you, guys, and a fair "Thank you" to those that are helping others.

question, are there still no diagrams that include the sda and scl points?

Rehius posted them a couple of hours ago here.
They will probably be included in the next revision of the guide by lightninjay.

Thank you. Is it the same power regulator we solder the 3v3 point on? btw I only used one MOSFET.

yes, but oled says not tested yet

Perhaps because, HE ONLY POSTED ABOUT IT SEVERAL HOURS AGO. This is a cutting edge mod, people. Things are constantly changing, and we're updating documentation as quickly as things can be tested and verified. The next update to the guide will include new/updated instructions for the picofly 2.70 firmware, as well as the new additonal points for those having boot issues (needing to reset their rp2040 during boot to get a glitch).

A little time and grace is all that is asked in return for these contributions being made to the community.

Pfft, excuses, excuses... You heard the temper, do the free work faster! <3

Sorry but what do you think? Would you say it's damaged?

I had a damaged MAX77*, right under the CPU

 

[QuiTim]

yes, but oled says not tested yet

Well I guess that's why you are here, to test things out just as we all are.
You could be the first to do it and prove that it works, and even if something goes wrong you'll have a support of this whole community so you can fix it.

Interesting. Is it one of those?

For lite and oled, SDA CSL needs to remove the motherboard and weld two more wires. I think it's easier to weld two mos

I think we need to find a relatively easy SDA SCL.

 

[angelC992]

What is SDA and SCL points? Only ok Xiao? Or is It something about 2040 Zero-Tiny too?

Thank you for your reply. I checked with a multimeter. these three red caps give continuity from both sides. The others do not. Do you think the chip is damaged?

 

[pausuri]

Quick silly question, can I use the cpu flex cable of a V2 on an oled?
