Hello @psycho-neon. Have chips manufactured with component assembly. I put three, all three flashed correctly. The first chip rarely does not turn on with the console, the second went well and the third directly does not turn on with the console. Have they given you any problems? I'm thinking about throwing them away and sticking with my Rp2040s, which never fail me.
Chips work fine friend. This is the 2nd batch. You have to check cpu pins to see if there is any bridge on your board.

All this chip is bcp made???? No in AliExpress like this???? Ready program!!

You my friend have the bestest English.

I'll do an attempt at translating for the others:
"Is this chip custom made, and delivered assembled and ready to be programmed? Not possible to purchase on Aliexpress?"

The answer is: Yes. You use the files from this post: https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/page-750#post-10367725
and make an order at JLCPCB with assembly included.

Getting stuck on the logo can only mean one thing, there's a problem in your system partition. Though I'm not sure how you managed to cripple both since its usually one and not the other since they are separate entities.

You probably made a mirror of your sysNAND when its on the brick going bust.
its 100% something hardware related. Just tried restoring my console by following level 1 and level 2 of sthetix guide and even wiping the entire nand and replacing it with a new one resorted with the same exact issue. Could there be something in the hardware side that could cause this? becuase it would be the only explanation onto why both emunand and sysnad both stopped working on the same time and why rebuilding my nand didnt work either and just produced the same issue

When Nintendo released firmware 17.0.0 they caused some problems.

The question was whether your nand backup was completely clean or that you already used it with a CFW?
Would resorting to a factory reset maybe fix such issues?
Another thing I was wondering is whether the BOOT0 and BOOT1 partition are used from the sysnand.
I saw someone that posted a message that he could not use the emummc without a physical sysnand/emummc.
That would imply that if for some reason there a some data corruption that affect BOOT0 or BOOT1 then you would habe problems with both your sysnand and emummc.

hmm, that could be the case, if boot0 and boot1 are damaged then that could make sense on how both broke at the same time.

Also the only nand backup i did was AFTER my switch got fucked. Just incase i fucked it up even more while trying to restore it back.

Unfortunately i tried restoring this console using all 3 levels of sthetix guide and none worked. I frankly dont know what else to try
