Hi,
I bought a "broken" switch on eBay (for parts) and to my surprise, it wasn't really broken. The person had AutoRCM enabled without knowing. Once I disabled that, the console (Which was on firmware 5.1.1) would only boot if I had CFW enabled (Atmosphere). Being new to the switch hacking scene, I only backed up the rawnand.bin, tsec_keys.bin and fuses.bin (I didn't dump BOOT0/BOOT1 because I thought it was included in rawnand.bin).
While on Atmosphere, I updated the console to the latest firmware (Im assuming I updated it to either 8.0.0 or 8.0.1). At this point, the console wouldn't even boot up (No nintendo logo or switch logo would appear). It was at this point that I decided to backup BOOT0 and BOOT1 while on this new firmware (I did not backup the rawnand.bin again). Without thinking about it, I flashed the original rawnand.bin back(The 5.1.1 dump) but the console would still not boot up. Reading online, I found a tutorial describing how you can patching your dumps for upgrade/downgrade. I used ChoiDujour to patch the BOOT0/BOOT1 dumps I took while on the new firmware, and I used the 5.1.1 firmware files to patch the dump rawnand.bin dump. I then flashed those files to my Switch and to my surprise, I worked! Kinda. I'm now able to see the Atmosphere logo, but my console wont boot neither on CFW or official firmware.
Sorry for the long story, but my question is as follows:
1) Can I downgrade my BOOT0/BOOT1 dumps from 8.0.0 to 5.1.1?
2) Im an idiot, I know, I should've backed up everything
3) Is this unit still recoverable? I don't know the history on it, but it looks like the NAND might've been touched before I even got this console
Any help would be appreciated
