Question about Android Backups, ROMs, and SPFs

[j814wong]

If I forget to backup my stock Android using CWM before isntalling a custom ROM (Epyslon's to be specific), can I always flash a SPF (JORDN_U3_6.36.0_SIGNED_USAJRDNTMOB1B4B5DE1028.0R_JORDANTMO_P022_HWp3_Service1FF.spf) to get it back to the stock Android?

I think so just don't flash an sbf with a higher cg version. You should look at the defy beginners guide. Its a sticky thread. It explains it in a bit more depth

This one is a Froyo for US T-Mobile. Is this your stock ROM? If so, then yes, you can always go back to stock, flashing this SBF (as long as you don't flash another SBF with higher CG39.smg version) This one has CG39.smg version 4, so as long as you stay away from SBF's with a higher CG39 version, you are safe.

P.S. I don't recomend using a nandroid. The only way to completely erase all sign of rooting and flashing custom ROM's is by flashing a stock SBF.
