Hacking Hardware Picofly - a HWFLY switch modchip

[malgamer]

hey a question here i have hack a few consoles now using picofly , all the samsung emcc boot in 1 sec , the tochibas are like ramdom time , its this normal in tochiba

Have you tested it yourself on TOSHIBA? and DAT0 and CLK keep 47 ohm?

my dat0 240 ohm , clk 50 ohm, cmd 50 ohm with this setup for toshiba emmc also have slow glitching issue

Lately i try multiple times glitching test by using 100ohms CMD on Lite, and problematic v2 emmc. It seems okay and safe. I don't know whether its Toshiba or not. I've once read toshiba datasheet and samsung datasheet, both specification is similar in number. So i dont differentiate between both.

Have tried 100 Ohms on Dat0, seems problematic, need more experiment. The last video on glitching i posted it. I use 100Ohms on Dat0. Somehow, sometimes its 1 sec glitch, sometimes 5sec glitch. And when i try off video again and again, theres a moment of 10sec glitch. Normally around 1-3sec glitch. Need more examination whether its because of the Dat0 100 Ohm or because of other thing.

Not yet experiment 100 Ohms on CLK. I still don't know the effect.

Try to replace cmd with around 100 ohms, and dat0 to 50ohms.

If we're gonna be picky, it should be pronounced Heck-a-Tea

I checked on the origin before making the post, both pronunciations are technically correct, but the modern Anglicism of the word is as I mentioned, HECK-eight. I normally pronounce it poshly, Heh-kah-tay.

According to this, hippy dave is the winner. It's been a while, but the last time I watched the movie Jason and the Argonauts (on Netflix), there was a woman who talked about this goddess and pronounced it as lightninjay mentioned, Heh-kah-tay. It's really hard to tell how to say it.

try swap 240ohm with the cmd 50ohm ?

ok i will try it later and share the result

Seeing Hekake just makes me think of bukkake, which I would prefer not to think about. Just a friendly little PSA

Is microscope boom rf4 use one lence if look and 2 lence i see only from right lence left lence is darkness????!!!

The scenario has been successfully tested

guys, we've been missing for a while.
I had doubts about the stability of fw 2.74, that's why I was installing 2.67.
Now I see that the problem has been recognized, and 2.73 is recommended.
Can I safely update all the consoles with which I installed with 2.67?
Or do I stay like this?

For 3.3v it is because to risky with flex or you double it or its just you still need wires? even with commercial flex.

Yes, the 3v3 pads are too far away

if you want to buy microscope. maybe you could look on hdmi microscope.

I say, if you still have hands on then yes you need to downgrade.
Although i personally waiting for hipotetical 2.75 with maybe 250mhz oc and disabled SDA/SCL feature. of course until i can compile the source code myself.

Any apparent changes in glitch time? or general stability if we compare with original pico instalation?

v2 need 100ohm.

Try to backup the raw emmc, usually theres show problem.
Benchmark the emmc might not triggered it.

Hmmm I don’t think it’s always mandatory. I did a few days ago a v2 with a rp2040-tiny and I didn’t have to add any extra resistor (just the ones which has the board included)

SDA/SCL feature have no effect as long theres no connection to SDA/SCL.
rp2040 tell the pmic to undervoltage via I2C using SDA/SCL. So if its disconnected, then the i2c request gone to BLACKHOLE

And the OC, the normal one is actually OverClocked to 200MHz. I don't see any issue yet on 300MHz. Please share us, if you really did have issue on 300MHz.

Compiling the source code is very easy. Even someone make a script for github to automatically compiled . You could just forked it, edit and push it, and lets github compile it using the script.

Editted: Now i see rehius has been included the script on .github/workflows/build.yml
So you just need to fork usk and busk, edit the build.yml change from rehius/usk, rehius/busk to your_github/usk, your_github/busk. Then edit the code you want to edit on browser (you doesn't even need computer, just a handphone with browser). Then goes to 'Action' and run the build.yaml action for github to build the firmware.

With 47ohms some problem, and some not.
Using 100 ohms its okay for both scenario.
In my logic, i will use 100 ohms, whether its slow emmc or not. Since it will be okay on both scenario.

For the people who are searching for good oled dat0 pcbs, I ordered here: https://vi.aliexpress.com/item/1005...il_item.3.1a50f19crRcduK&gatewayAdapt=glo2vnm
They sell 2 different ones, the bad Oat0 ones and Dat0 V6. I ordered the V6, i will report back when i got them but takes 12 days at least..

the purple happends when after a 10 power off and on train to get to hekake , but only ofw , the issue go away just by putting the battery of and on . iam isntalling BUNCH OF THINGS TO THE EMCC 40mbs no issues , just to see if i can see a issue

any magnetic fusse out there that i can buy and sother to the reset on the pico ?

you could use these to reset the pico if you don't find a fix for the problem
https://vi.aliexpress.com/item/1005003372450508.html
maybe use the "normaly open" model and solder it to reset button pads on pico

I buy rf4 boom microscope with 2k camera rf4...i think that only normal can see from one lence and the other one is darkness... Normal!!!!!

I don't think its normal.
Last time i use microscope with eyepiece, it shows picture on both eyepiece.
