So far I'm really content and pleased with the rooted Sony stock ROM on my device. All working very stable and smooth.
But I would like to have CWM for flashing things.
So, the bootloader must be unlocked, but if I read correctly, all data will be lost.
Would the following be possible to circumvent needing to re-install all apps, re-set all settings etc.??
a) First make Nandroid backup via OBackup app, save to external SD or NAS.
b) Unlock bootloader, lose all data.
c) Install CWM.
d) Restore nandroid backup via CWM -> system up and running as before the operation, like nothing had happened.
???
Or will there possibly be problems with OBackup-produced Nandroids??
And am I right that I can do this on a SGP311 with .370 firmware? No need to downgrade to .344 first?
