Hardware Switch oled kamikaze fail

[jetuaime81]

hi. i have failed miserably in my kamikaze attempt. I have taken some diode readings (red probe on ground). Is there any way to recover this? Also the point marked by the arrow seems very big, which has got me real confused as to what layer i am on now.

I have the necessary tools for joining the connections.

thanks in advance

Maybe that can help with your repair attempt.

If everything fails and you consider throwing the board in the garbage bin, lift the emmc and wire it up manually.
It's only 14 wires or let it run in 1 bit mode (only use DAT0) to bring it down to 7 wires.

Thankyou. I have been through multiple posts and these files of layers. Unfortunately, after a certain point I am completely lost.

I didn't understand the emmc part. Is it something that would make this switch turn on again?

You can grind the area to expose more of the traces in the inner layers.
But there is some limit to that and if you grinded so much that there is nothing to connect to,
you can consider removing the emmc, flipping it over and use very fine coil wires to connect those 7 lines to the mainboard again. You do need to prepare that DAT0 line and the other line you severed.

Now that I think of it, check if that other line is a data line (DAT1 - DAT7).
In that case you can get away with only repairing the DAT0 line.
The Switch will run in 1-bit mode but the emmc is only used for booting.
Once Hekate is started, you probably use an emummc, which runs from the SD card anyway.
If the other line is something like the RST line, then you will need to repair it.

Not my work, but I did something similar for a client's smartphone emmc :

Oh.. that's a whole lot of work, I don't know if i should try. let me do some research on 1 bit mode, first time I'm hearing about this thanks for pointing me in the direction.

I was just thinking of installing a dat0 adapter and seeing if I get continuity on the point with the arrow in my photo. Will try that first and update.

Great news. The black arrow marked (in the above pic) is the dat0 point. I temporarily inserted the adapter under emmc chip and check the continuity with this point.

So I am thinking of joining a wire like this and try to turn on. Whats your opinion?

@thesjaakspoiler I was successfully able to boot the console. Thanks

Nice work. You may be the first one to recover from one of these situations.

Thanks. I have seen a few videos on youtube on fail recovery. But yes, I got lucky i guess, I had very uneven grinding and also the fact that there is only ground layers in this area on inner layers also helped. The pointed 0.5mm bits are more like a drill bit than a grinding bit, maybe it's my technique.

But i have now switched to spherical tipped bits like these. I have more control now.
