i done this i resigned my old trophies from my old account and put them in my new account.
took me almost a month to figure out how to upload them, turns out it was because i was on rebug rex edition, that's kinda like dex, dex consoles can't sync, so yeah.

it's possible.

there were 2 games who missed timestamps but it was normal since it was a common problem long time ago.
just installed a fresh trophy list and hacked the trophies i originally had on my old one with legit looking time

Sony dont ban for timestamps they ban for CFW. If they ban for timestamps then official firmware users who use saves will be banned too. I've even spoken to them on the phone they don't care about trophies or the level only custom firmware users.

And how are you going to reinstate trophies from one account to another........ by using a CFW machine!!!!!!!!! Sony knows that, ask any number of people on here who have banned accounts from trophy hacking. You are a complete idiot if you believe what you just said as most (not all) trophy hacks are done using CFW and the other way is by resigning peoples saves. Both of which are easy to spot if you know what to look for

Theres something called syncing on ofw. I've never been ban and never will.
