Very good night. Could someone help me, how to edit that written part of HEKATE.

They compiled hekate from source and changed some string in probably nyx.c
https://github.com/CTCaer/hekate/blob/master/nyx/nyx_gui/nyx.c
That custom string ends up in nyx.bin :

Not sure if I can post this here, but I'm getting somewhat desperate since there seems to be a lack of information on my issue.

Recently I discovered a short on a capacitor beside the sd card/game card reader pcb port on an HEG-CPU-01 board I've been trying to repair.

My question is if this is shorted, is there a chip that may be defective & this is simply an indication of its failure, or does the capacitor need to be replaced itself?

Also what would the value be of the capacitor if it needs to be replaced?

Any help would be greatly appreciated. Thanks!

That component is in normal state. Don't waste your time on it.

And which good adapters can I use? Is there any photo where I can see which ones are good? Thank you

I wouldn't. A solder-covered contact point won't work any better (unless it's actually soldered) and the ENIG finish at least won't oxidize.

I ended up testing it some more & found this out after frustrating over it, thanks for the reply though! I appreciate it anyhow.

I got blue, white light and then my screen went black. No "No SD card" message. Does anyone know what I did wrong?

Post install pictures - post diode readings on all points and also what switch console

apakah ada yang mengalami masalah ini?
saya berhasil masuk ke hekate 5 kali pertama
saya mencoba mem-boot hos dengan 2.61.uf2
emmc yang didukung, dibuat emunand kemudian ketika setelah menyuntikkan hekate 6 membawa saya ke masalah ini
saya mencoba membersihkan picofly dengan flash_nuke.uf2 tetapi tidak berhasil sama sekali

Actually, I resoldered all connectors and now I'm getting the =*** and =*== error. eMMC init failed I guess. What could cause that issue? Switch Lite

I'll send the values in a bit.

Edit:
GND: 0.200
3v3: 1.103
DAT0: 0.880
CMD: 0.850
CLK: 0.970
RST: 1.870
CPU: 0.687

Yeah, still getting this error. Can anyone help me on how to fix it?

Hello everyone, It will be possible to rebuild the picofly fw with a different payload ? (payload.h in the picofly repo) I found the Spacecraft_NX sdloader repo and I was thinking if it was possible to use it instead of the picofly one.

This normally happens when you soldered onto the wrong points. Can you please recheck the schematic?

Also really hard to see anything with the solder mask on top. Should check to make sure it works before applying anything in the future.

Yeah, that was the issue... The RST was on the wrong point. I resoldered it on the correct place and the chip gives me a blue light (training) then yellow but the screen stays dark. It's on but it's black

Then you must have messed up your fpc connector(daughter board to main board). It's the one that goes over your battery connector if it's a switch lite. If the connector between main board isn't working, you won't get backlight on the screen hence it stays black. This is a very common mistake when modding the lite.

Small black chip near 3v3 capacitor point get worm if tearn on console and the console some time working some time tearn off. The picofly blue light then yellow black secreen. I dont know what happend. The point rst is 1.1 v not 1.3 v 3v3 some time 784 v some time back to 0.801v and some time dowen to 0.645v...cmd is 0.530 v clk 0.645v
Oled console 18.0.1
