Hello everybody got an issue that I hope you all can help me with. A while ago a friend of mine accidentally liquid damaged his V1 Switch. I have been able to repair the power systems on the logic board and as far as I know, it powers up (460 mA when charging). I can boot into Hekate just fine. Unfortunately, his NAND was destroyed when the Switch was damaged. I have several spare NAND boards from donor boards. I followed a guide to essentially rebuild the NAND using a donor rawnand.bin and the console's prod.keys which I was able to extract in Hekate using Lockpick_RCM. When I attempt to boot into OFW it shows the Nintendo logo for a second or two then the screen goes black and the Switch shuts down. Also, I do not know if this is important but when I attempt to run Lockpick_RCM it tells me Keyblobs 0-5 are corrupt all other keys were extracted.

Basic info:
SKU: Erista
Burnt fuses (ODM 7/6): 11 (FW 9.0.0-9.0.1) I used FW 9.0.0
AutoRCM: On (I intend to disable this when I can boot into the OFW)
Checked BOOT0 & BOOT1 in NxNandManager both report OK

UPDATE:
I updated my friend on the status of the Switch and he told me that not booting into the FW issue was a common occurrence prior to being damaged by liquid. He has told me that it started about 2 months after he bought the Switch.

As far as I know, you can't boot into OFW when you use a NAND from another Switch because the OFW checks the NAND with the serial from the Tegra cpu.
This doesn't match up because the donor Switch has another serial number.

See I was hoping to rebuild the NAND using the proper firmware version, my friend's prod.keys, a new PRODINFO from scratch for his Switch (this generates a blank serial), and encrypting the new rawnand.bin with the prod.keys would be enough to overcome this. I have never had a NAND die before (his original is internally shorted to ground) thus making this is the first time I have tried a NAND swap. But I figure it should be possible seeing as people solder larger NAND flash chips to their Switches. I haven't tried to boot into any CFW like Atmosphere yet. I am back in the shop today so I may give that a try after I get through my queue.
