Hardware Changed bq24193 now BSOD

[Ttm3]

Switch was loading Nintendo screen then going black. Something looked off in the battery data in hekate so I changed the bq24 on a whim. Now it has bsod. Bq24 won't cause that will it?

No ! .....BSOD - Nand corrupt or bad eMMC, bad soldering memory ram, bad soldering SoC Nvidia Tegra, logic board bent.

That's what I was afraid of but it just seemed too coincidental that I just changed the bq chip and it started after

Reflow ram and cpu.

Hi guys.

My switch shows the Nintendo Logo and then goes black. I already tried another battery.

I switched the eMMC "clip">same result.

I checked all things around the power chip>ok

What else could it be?

It's not a hackable switch.

what do you mean switched the emmc clip?

 

[Bohne]

Switched=swapped.
eMMC clip is this small board the eMMC chip is soldered on

 

[Ttm3]

I understand that much... did you desolder it and put it on a new board? did you replace it with one from another unit? what exactly did you swap

 

[Bohne]

It's very simple.

I just wanted to see if the faulty switch will just show the nintendo logo with the donor eMMC.

I did not do any soldering, just swapping the clips including the chips.

How can I find out if the eMMC or the clip is faulty?

 

[Ttm3]

according to all available knowledge the emmc is paired with the processor (and wireless chip). It will never start with a different emmc. Additionally if the emmc from the donor board is on a newer firmware it will burn the fuses in the processor as soon as it attempts to start and it won't be able to work with the original emmc even if the issue is fixed.

And it's not possible to use a hackable switch to copy the eMMC data?

 

[Ttm3]

I have read of people doing that but never attempted it.

Not exactly the same situation but in hekate it is possible to backup/restore Nand from another device
