[Q] I9100XWLS8 (4.1.2) - Spain (FOP) [23-01-12] factory reset considirations - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I'm considering to install this ROM and do a factory reset in order to clean all my carrier bloatware and customizations.
I'm wondering what should I expect to get in term of used memory and system storage after the factory reset?
I'm going to backup the following before the factory reset:
1. SD storage.
2. Possible phone based contacts.
3. My carrier APN
Anything else I should be backing up?
Thanks!

You could use Titanium Backup PRO to backup your user apps/appdata so that apps/app settings etc are restored.
No need to backup contacts as they're synced to google account and will restore when you re-enter account details.

That requires root access, which I have in my current rom, but also for the new rom.
Is there a tested rooting method for this rom?

Nice!
BTW, is that Siyah kernel based on the same original kernel build which comes with this rom (3.0.31-816988)?

No, that siyah kernel is not based on this Official JB4.1.2 kernel build but the earlier Leaked JB v4.1.2 for u

Couldn't this mixing of this official release and a kernel from the previous leaked build be the source for some unexplained bugs?
Besides that I've read the Siyah 6.0b4 release notes and I saw that they have some known issues (like startup scripts not running).
I'm hoping to get a more stable installation than my current rooted I9100XWLPT (4.0.4) (not sure which root I've used).
So I'm looking to do things more careful with this release, so I'll get a stable running phone
I imagine that Siyah will release a new build for the official release pretty soon.
I waited until now, so I think that I'll wait a little more.
Thanks for all the info and recommendations!
