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.

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

CMD: 0.850
CLK: 0.970
RST: 1.870
CPU: 0.687

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.

hello mr fake hwfly aliexpress seller, yes it's possible but there's no legitimate reason to do so.

hello mr seer, the batteries inside your crystal ball have run out, your assumptions are wrong since I'm not a seller. I got myself the picofly recently and I want to customize the sdloader payload to achive two things 1) have the battery level expressed in millivolt and 2) change the logo with a mario one simply because I like it, that's all. Since the github repo for the sdloader and the picofly fw are publicly available I thought it was not a problem to do it. I apologize if my intent has been misunderstood. In any case thanks a lot for your feedback !

It's not that the screen is turned off, The led pixels are on but they're black. Is there a way for me to check if the fpc connector is the issue? Doesn't seem to have any scratches on it either
