As soon as possible I will tell my friend to try this xplorer.bin and format the sd and put everything back to 0 and run hekate again from there. I will tell you something as soon as I can prove all this. thank you so much

I let it run into it turned off and never got any yellow lights. I will try again today. I think it may be the dat0.. it is one with 3 tabs. I think the tab that goes over to the cap is blocking me from getting it in the right place. I have it over against the cap.. I’ve seen older video where sthetix cuts the small extra piece off that tab.. I will try that.

This is not a good adapter, the point is too big/wide
It should be more like in the photo

That is the famous 3 pin dat0 adapter.
Its failed product.
The 4 pin dat0 adapter is what recommended by the community.

I experiment with those adapter previously, to make it work. Modify it a little bit. And its work.

Basically that part which i give red box is the area that i cut apart.

I will do that. Thank you!

I noticed that the ums-loader uses IRAM only to boot, and works well when others payloads doesn't works.

So, can we modify other payload to make it works on IRAM too?

I know that IRAM only has 256kb if i right (maybe not xD)

Just a crazy idea to think that i don't lose my lite.

Omg these adapters are just horrible. If i where you i whould though them away and buy new high quality adapters.

just tried with the xplorer file and directly purple screen without letters or error on the screen. It seems that the problem is serious and surely it is in the gpu, ram, or even in the nand. what do you think?

Lets do another test.
- Open the switch, unplug the battery and remove the emmc board. then plug in the battery and turn on the switch (it should not power on)
- Then disconnect the battery and place back the emmc and reconnect the battery and tell us what happens

I think what killed this OLED is using my new soldering station without knowing it very well. I did another OLED and worked perfectly. Can't get enough of soldering MOSFETs.

my very first install I did the individual mosfets just like this.. I rather enjoyed it but it took a lot longer than just using a flex cable. Very nice work!

Sorry. The pressure tests have already been carried out previously without any success. My friend is from another country, I can't be with him I don't know if I'm applying enough pressure here either. I'll tell him to try all this again just in case before continuing to try other options. Thank you

If I'm not mistaken, I think the cable should be soldered here. let the companions confirm if this is correct.

should be bottom resistor

He has already tried these tests right now and if he does not have the nand directly connected, neither the switch nor picofly does anything. if you reconnect the nand do the same as always : ( without success

what resistance do you mean? Could you give more information or show a picture?

Seems like the same issue with that.
Have you tried that ums-loader?

I just told you to try this now. In a few minutes he will tell me something and I will let you know what happens. thank you

Test performed. this now appears with UMS. now what next?

Uhhh, he should check with hacdiskmount if can read the GPP partitions and BOOT0/1

If those things read well, we'll be in the same situation xD

What would be the correct use of this ums payload? What would be the steps to check the units and detect where the problem is?

Just select GPP and Boot0/1 and push power button until RW appears on the right the same as SD Card, mount it after that and plug the Switch to the computer, download HacDiskMount and check the physical partitions.

The same as making a backup.
