How do I get PokeBank to accept a 8F Mew?

[Maetch]

I did the whole process with the 8F item to the letter and everything matches up. OT and number are correct and it's at least Level 5, yet Bank still won't take it. I was told elsewhere that there's trash values that are blocking it out, so how do I fix those? Or has Bank simply been updated to block ALL Mews regardless?

There is likely still some values that are being flagged. I can confirm that the GF VC event Mew are not blocked, there have been no updates to Pokémon Bank/Transporter of that nature.

And what would I have to do to fix those values, if possible?

I'm not familiar with ACE/glitch pokemon, but you could open the savefile in PKHeX and compare to a legal copy of the GF Mew from the Mystery Gift Database.

Finally found a Mew here that passes. I took it into Gen2 and the name was now MEW??????? and the OT is GF?????, but it cleared up once it went to Bank. I seem OK now, so thanks for the help.

Trade it via 3DS VC, instead of using a combination of emulators and PKHeX. 
 

(it sounds like an issue I experienced in the past)
