(I'm using a N3DS, 16GB micro sandiks) After I had downgrade issues on monday I managed it using PlaiSysUpdater with no errors. Now I tried to proceed to the next step in the guide where I have to use the OTP One Click Setup but it fails on Verification 1 and 2 with an error that is not described in the troubleshooting guide. http://pastebin.com/g0Xys32v So I restored my formatted emu_nand, downgraded again but used the "unbrick emunand" function before attempting another One Click Setup. Which again resulted in the same error. The Troubleshooting guide refers to mismatched TWL hashes but this seems different.
