Surely a full wipe (data, cache and dalvik) would be ok? Best to be save than sorry :thumb:

Restoring apps is easy, get titanium backup pro and back up all USER apps. Once youve flashed the new ROM, download titanium from the play store (and probably the pro user key) and just restore all user apps. The back up and restore are done in a batch procedure (as long as you go to the batch section ) so you dont have to do anything!

It will keep your data and launcher settings although widgets will need to be put back in their place

 

Pretty sure Wanan said at the time that full wipe was necessary when going from MR2 to new base. This was a while ago so think you'd definitely have to do full wipe to jump to latest version.

No hardship doing batch restore in TB for your apps though - but you need pro key for that. You can do each one manually with free version if you have the time and can be bothered, paying price of a beer or two to avoid that alone was worth it for me

 

Yeah its defo worth buying pro :thumbup:

 

Most rom updates dont really need a wipe but when the dev specificly says it does, theyre probably right. Like you though, im lazy and always try it without the wipe lol. If it doesnt work, you havent lost anything so its cool

 

I've found I can back up my mobile data, sms and call logs with TiBu without it causing any problems aswell

It used to take me ages to set it up but I can flash and have things set up within 20 minutes, the longest part is resetting all my widgets.

You can also make a flashable zip in TiBu which takes longer to backup but is far far faster to restore. Did it last time and it was spot on!

 

I think it's the same as a batch backup, you can either backup everything, system or just apps but it obviously turns it into a zip file :thumb:
