[Q] FTF backup of a "modified official rom"? / CWM x Rom Manager
I know it's not the subject, but this being my first time posting here let me start by thanking all of the developers and collaborators for the great works in this community! I have already benefited from a few tutorials and files disposed here, so thanks for everything so far!
Back to the subject now =)
Although I am using an official rom in my Xperia Neo, 2.3.4 (4.0.2.A.0.42), I made several modifications to it and I couldn’t find a similar thread involving a "modified official rom", I only read threads describing how to make a simple FTF backup of an "untouched official rom" through SEUS, which I presume that won't work in my case. So I hope the more experienced people can give me some directions!
My device is currently rooted and the bootloader is also unlocked through the official Sony method. I substituted the original kernel for the Inteks so that I could use cpu overclocks, removed all the bloatware and integrated some updates and a few new apps in the system through link2sd.
Now I'd like to make a backup of this modified rom before I flash new roms to the device. For what I understood so far, the recovery nandroid backup system will save everything, including installed apps and configurations, right? I'd like to make just a simple rom backup.
I'm afraid that this nandroid "full backup" could decrease the performance after restoration. If I perform a factory reset prior to the nandroid backup, could it minimize the chances of having problems after restoration?
I'm asking this in case there is no manner to create a .ftf file… And, what you guys think about both types of backup, am I getting the wrong impression about nandroid or .ftf files are really better and/or safer??
I installed the app Rom Manager to check its features. It seems it only performs nandroid backups as well directing to the recovery (hope I got it right), but I ended up noticing an issue. The app asks to install or update the CWM Recovery, I tried to update but I get a message saying my device is not compatible.
The current recovery installed in my Neo is "CWM-based Recovery v18.104.22.168-nAa-r2".
Should I update it? And if it's the case, how should I do it??
Is my device really incompatible with Rom Manager, or that message I got was because of the old recovery version installed in my Neo??
(I read about this kind of incompatibility with some devices, just wanna check if it's the case with my phone and if there is a new recovery for Xperia Neo that is compatible with Rom Manager)
Sorry about the long text and so many questions in a single post, but I really want to understand more about this stuff, all the changes in my phone were done separately during more than a year, so I am not much used to these procedures.
I would appreciate any help! Thanks for the attention!!
