Hacking Hardware Switch OLED SkHynix with Picofly long boot-time

[superfiege]

Probably 1-3 seconds. 0.2mm magnet wire from mosfet to drain and source, then 36awg from gate to tiny.

OK, so I think the main problem with my long glitching-time is in fact the apu-flex-cable. I will replace it with a single-mosfet install and give feedback.

Some eMMC are slow at glitching. Whether you use a single mosfet or the fpc. It doesn't matter the scenario. Its within the firmware of the picofly support. You are just waiting your time replacing a component. You might as well break something. Other users here already mentioned this on your previous posts.

Thats right, but others said its worth trying…and i love soldering so its not wasted time. And in the end i learned a bit…even if its not improving glitch-time.

In my experience, glitch time is mostly related to the mosfet setup. I've tried all combinations of everything (mosfet on front, back, double or single, different wire thickness, wire length etc) and the setup that I find performs the best (tested across many switches) is 0.2mm thick wires attached like in the picture.

0.2mm is risquy man in these conditions, but so you probably have more soldering experience and tricks than me...
I use a flex for V1 or V2 with all integrated, easy to find on aliixpress so, I will always respect dudes but honestly when you can do it easily do it I can have the 10 flex cables for v1 or v2 for 2 dollars, ridiculous, even the rp2040 chip is ridiculously cheap 2 dollars maybe

I had always chose for the single MOSFET directly on APU. The results are almost always instant boots.

Could you give an update on your results? How did the new adapter go?

So how did it go? I'm really interested to know. My Samsungs all boot within 3 seconds while a SKHynix can take up to 16 seconds.

If anyone is still curious about how mosfets effect boot time...

I am not the OP, but I did stumble upon this threat while dealing with a stubborn OLED also with an SKHynix nand. Soldered perfectly using Kamikaze method, it was still taking 1-3 minutes to glitch.

Replaced the chip > same problem

Replaced the mosfet flex and soldered it to the chip directly > boots much faster now. Still one of the slowest I've seen, but is now 45 sec maximum. Mosfet definitely plays a large role in boot times.

I take it back. I think I got a few lucky boots when I made that comment. Boot times are still ultra shit. Not sure how to proceed with this one.

You should try an instinct NX V6S

I don't think they are made/sold anymore

I found one laying around! I was so so hopeful, but the system still boots extremely slowly even with the instinct chip. I have never had a system this stubborn in the last 100+ installations.
I have tried all types of different chips (Cheap aliexpress chip, official waveshare, JLCPCB tinyfly, and now the instinct) but the system only glitches half of the time and when it does glitch, it takes over a minute.

I have exactly the same problem. I have used the kamikaze method. All diode value are ok. But sometimes I get === in glitching attemps without lucky; and others it launch hekate without problems taking between 2-80 secs

This just happened to me aswell, all other v2, lites, oleds I’ve modded have after the initial training(which usually takes 5-10seconds) would successfully glitch almost immediately. But I have an oled now that is very bipolar, sometime glitching on first first and other times it can take several minutes. Tried switching chip, retraining data. Still the same

SK Hynix is just inferior to Samsung.
