how do i get my sav files from the old version to 10c? pls help
You can't.
Aesthode changed a lot of scripts and flags, so you need to start a new Save.
I'm currently stuck for getting the HM Surf, the problem is there is a rock that is in the same position of the HM, so I can't continue the story.
I hope this glitch will be fix in Beta 11.
Do you mean
these or
this?
For the first ones, you need the HM04 Strength.
Just go to the Diglett Cave which it's at the end of Route 15 and do the Fossil Hunting Event till its end.
The second one isn't a rock, it's a platform.
Just walk at its direction and you'll be in the Underwater Zone to get the HM03.
You'll need to use the itemfinder to trigger an event tho.
EDIT:
im new here
1. sorry for my bad english
2. can anyone teach me how to get the mega stone? it's only VenusaurY, PolywrathY and PidgeotX in my pokedex

and i can't go to the Pumello island
3. where is entie, rayquaza and ho-oh
1) Don't worry, no one it's perfect, my english kinda sucks too xD
2) NidokingniteX it's at Mandarin Island.
You can get the Sceptilite, Sharpedonite, SteelixiteY, Slowbronite and Swampertite by having a Pokmon with Pickup in your team and checking which item it has equipped sometimes.
I can't remember where the GolemniteX and RaticateX were, but they're really near of Pumello.
And i know the PolitoediteX it's obtainable too, somewhere..
But the most easiest solution it's reaching Pumello, the island of the Orange League.
3) Ho-Oh is in the Cave of the Orange Archipielago's Ending.
Rayquaza.. i don't know, i've just found Groudon and Kyogre, sorry ;_;
