[Sony Cross-Device General] Gambion:
Acro S claims to be unrooted

Hiya,

Bought Sony Acro S, decided to flash cyanogenmod 10 in right away since the original firmwre kept crashing even after updating the key apps. Also, bloatware :P

I rooted the phone with Eroot, and installed CWM. After checking several instructions decided to go with installing CM10 and gapps from sd card, as I'd done previously on my GT-I9000. Wiped data, wiped cache, wiped dalvik, installed zips, reboot. Fail, phone ended up hard brick.

Followed the tutorial and got from hard brick to soft brick. The phone charges alright, and I get it to both flashmode and fastboot mode. I tried flashing, but no luck, heres the log:

Just for the sake of it, I tried flashing the kernel with fastboot, and for some reason fatboot seems to claim that the phone wouldn't be rooted?

I downloaded the stock ftf straight from Sony, and did select Nordic version, so I assume I should be having the correct version.

Any ideas? I'm starting to be at my wits end with this one...

Thanks in advance. :)
