What are the risks behind unlocking bootloader and most importantly, what do we lose after we unlock it and lose the DRM codes? Do we lost the inability to receive official software from Sony over PC Companion?
Thanks in advance!

i was able to use again PC Companion, after i have relocked the bootloader (stock rom doesn't seem different)
just remember that this will wipe your data!

I have relocked the bootloader though..
It doesn't matter: the certificates were wiped and PC Companion can't give them back to you.
It's just a fact of life I guess

Hi.
I'm selling my Arc, and I need to change it back to its original state somehow. I need to install SE Gingerbread and delete CWM. How can I do so? It needs to be warranty-ready.
Thanks.
Just re flash using flashtools it will delete root and all traces of mods etc..... The only thing it will not do is relock the bootloader.

You can also relock the boot loader. Search for Xperia relock boot loader in the forum.

though u use flashtool n also relock the bootloader,u wont get the drm rights back. (ie) apps like TrackID still wont work. But that wont be a major problem.
Hello guys I'm new here. Just rooted my phone last week (Sony Xperia Acro S LT26w) and i want to install CM10. I managed to install CWM recovery without unlocking my bootloader. I used this filefrom the post reply of Pims83 at this thread. I installed CWM recovery without unlocking the bootloader because everytime I try to run my LT26w into fastboot it always ends up in usb charging mode, Blue led come in like 3-5 seconds and will disappear. My question is, can I install CM10 to my locked bootloader LT26w using this method?
Nope

so i really should unlock my bootloader?
Yes.
Lock bootloader = stock kernel
Stock kernel = no cm10

After unlocking my bootloader and backed up my files, can i install CM10 right away? Will my files from my external sd card will get wiped too?

To get something u have to loose something.. There is no other way available.. You can take backup and restore.. If u dont want to backup restore then u have to stick with unrooted phone

There is probably a backup of TA.img on mobile.. It'll be in the sdcard. That's the home folder.
