Hi guys!
Fist of all, I'm so sorry about my poor english, I'm from Brasil and you know, thats not my native language

My friends, my uncle come from Japan and give me a Acro, I already have a Arc, so I just try to flash the Acro with Arc firmware (ICS Stock), but the phone just get infinity boot loop. I can't enter fastboot mod, Its just like the phone dont ir recognize the drivers, I try many tutorials, in english and portuguese, but I can't. My question is: Will some FW work normal on my Acro? I need to unlock bootloader in order do flash my phone? What can I do?

Thanks in advice.

Arc and Arco r different ,coz Arco need to find a way to unlock the bootloader first
but I can`t find a way to do that
and I am using it out of japan...so some tutorial in japanese is ....
