Yeah, just follow the TroubleShooting. But i also thought the section about removing Rockbox should be revised.
Because it doesn't mention that you should rename the original firmware to PP2022.mi4 before placing it back into the root directory. Also the removal section should also include that you should keep OF.bin in the /system/ directory just in case situations like saratoga's happens (at least this way you can still boot the original firmware and then attempt to rename the original mi4 firmware to PP2022.mi4)
I didn't know that the original firmware needed a specific name and thought i had messed up my Sansa. But luckily i still had the OF.bin in the system directory and was able to boot the original firmware ,temporarily, by holding left.
Just some suggestions. Hopefully they'll be implemented to the wiki page! It'll surely reduce the number of lost people trying to remove rockbox
