Hardware 21001-0001 replacing cpu possible?

[fa2k]

hey guys,

im getting a 2101-0001 error message. After replacing m92t (multiple times ), bq24 and pi3usb it wont disappear. I can boot into hekate, but as soon as i try to start something this message pop up.

- no shorts around chips
- 0.46 amp consume, doesnt switch to fast charging
- android with wifi and bluetooth is working on this switch btw

i replaced the cpu once, but atmosphere had problems to see the SYSTEM partition. got a "NXBOOT SYSTEM Partition must be corrupted" message. It pops up if the loader isnt able to get the Contents folder of SYSTEM partition. But with nxNandManager im ablet to mount this partition and see the contents folder

Later i placed the old cpu back and got the 21001-0001 error again.

Now im lost to get this console working again and hoping for some ideas

If you swap the SoC you also need to swap the eMMC.
The eMMC is encrypted with keys derived from device unique keys that are burned into the SoC.

well, i swaped it because the orign board has a faulty emmc

will lockpic read out the "new" cpu keys after replacing the cpu?

will lockpic read out the "new" cpu keys after replacing the cpu?

No, it's not that simple as simple keys extracted via Lockpick.

ok, thanks. do you have any suggestions regarding the 2101-0001 error?

from my experience, I solved it by replacing m92 to get rid of the error. i would check in diode mode near the m92 chip

i went through all resistors and caps around the chip, even compared them to working switches, but all look good. i really dont get it.

But i found something weird. Maybe someone knows how the switch knows that a charger is connected or not

Here the hekate battery status. It always shows its charging even if i dont plug a usb cable
