Since I wiped all my data and was able to flash a custom rom, how do I get back to stock?

I saw a thread for all the other variants on this but not one specific for sprint.

Or does anyone have a clean stock back up file they can pm me? (Is that even possible?)

I've been reading the guides so let me clarify: if I can get into download mode, I can skip the first guide?

And I don't see sprint DLL or tot file. Can you point me to the download?

Appreciate your help on this.

Is it possible for someone to make a nandroid backup of their stock ROM, then post a DL link?

Then we could just DL the backup, manually copy it to our phone to the proper folder, and restore it through TWRP or CWM. Does that work?

I've never tried but it seems much more simple! Sorry in advance if that is a stupid idea and doesn't work. If not, explain why!

No that doesn't work because you can't make a backup in TWRP or CWM of the stock based ROM when you are unrooted since if you are unrooted you can't flash TWRP or CWM. The earliest you can make a nandroid backup is right after you root and flash TWRP recovery.

When you do an OTA, the Sprint stock OTA update looks for valid files in certain directories that the root method might have changed and any certificates might be invalid so it doesn't install. That is why some folks who rooted and then do the OTA and the OTA install fails and they get bootlooped. This is why they say if you are rooted, do NOT take the OTA update. If you must, like in the case of Verizon you should take the OTA first when you are unrooted, let it install and then root.

Am asking because I thought that the zip file we all downloaded could be flash via recovery and not just the flash tool?
