Hacking Hardware Picofly - a HWFLY switch modchip

[Switxh]

I'm using 2.74 on my OLED with slow / sporadic glitch times and it seems not much has changed that I can tell so far. Really stumped on what is causing it because I've been over every joint and changed from CPU flex cable to dual mosfets and nothing seems to make even the slightest difference to the glitch times. After updating the firmware I rebooted the Switch quite a few times and seems the average glitch time is still around 10 seconds. With highs of 20+ seconds and lows of ~2 seconds.

It has still never failed to glitch so far so that gives me a bit of confidence but it's not a great user experience having to potentially wait 20 seconds after pressing the power button for something to come up on the screen so I'm still not happy with it.

Latest firmware doesn’t rely on flash color, just pulses. If it flashed once after flashing firmware, it’s ok

From what I've read people still aren't doing backups as soon as they get into hekate.

Skipping backups or delaying them should not be a thing people do.

As soon as you get into hekate;

Backup, backup and backup.

If for whatever reason your boot fails after you have gotten into hekate for the first time and it won't boot hos after that a backup can save your skin.

First thing I learnt back from the ps3 days and I learnt the hard way, always take your nand backup as soon as possible Im case of bricking.

Backup emmc gpt (or raw), boot 0 and boot 1 and your key files. Then back them up on pc. Then backup the backup.

Seriously those files backed up can save you trouble down the line.

If you get it installed by someone ask them to provide you with your backup files or do it yourself as soon as you get the console back.

What would the changes we should expect from this?

It's a special build that simply removes the SDA/SCL point cpu voltage lowering functionality. I wanted to test 2.74 glitch times on my switch without sda/scl, but without having to open it back up and remove the wires. If you haven't soldered SDA/SCL then it behaves exactly the same as the regular 2.74

Thanks for the update

There no caps on nand point.
V2 for reference.
V2 is the easiest, Lite harder, OLED maybe ill try next, V1 haven't met any V1 yet.

I would say the lite is easier than the v1/v2. it has a much easier 3v3 point, and doesn't require any shield cutting. The other points are about the same difficulty, simple (but small) test pads on the motherboard. Everything accessible without removing the motherboard on both models. The oled is by far the hardest though.

Lite < V1/V2 < Oled

Does anyone ever face with this problem? when it boot into OFW, it stuck on Joycon logo. then it was boot into CFW and it loaded atmosphere logo and after it turned into black screen. Anyone know the solution, pls help. thanks

test Benchmark eMMC raw speed 160ms or 340 ms ?

Hello. I installed Picofly with two MOSFETs as usual. Got the logo, but when I insert a fully functional SD card I get black screen. Pressing the power button for 10 seconds gets me back to the forbidden fruit logo.

What are the possible scenarios? I'm pretty confident with how I installed it.

Did you attach your ground wire near the SD card reader?

Did you attach your ground wire near the SD card reader?

Hello,
No I used the cap like it says in your guide

 

[lightninjay]

Hello,
No I used the cap like it says in your guide

and with no SD card inserted you get a NO SD CARD screen?

hi, i fixed the picofly flash issue hahaa, chip full instaled, but the picofly blinks one time dark blue and nothing goes on

 

[FreeLander]

and with no SD card inserted you get a NO SD CARD screen?

I get a NO SD card screen even without SD Card. It's not until I insert an SD card that I get a black screen. I changed SD card slot and tried another SD card. Same thing

you mean 2.74.

and yes, this is the slowest glitching switch that has passed through my hands yet, out of about 12. most others glitch almost instantly
