When you say :
Upgrading from an earlier version of CyanogenMod 10:
Copy CM10.1 ZIP to your internal SD-Card
Boot into Recovery
Flash CM10.1 zip from internal SD-Card
Reboot
you mean earlier version of cyanogenMod 10.1(4.2.1)? or i can upgrade from cm10(4.1.2)?
You can update from any version of anything as long as you have CWM.
“Restoring Apps + Data might cause problems and is not recommended, avoid it if possible!”
so we cant’t restore the data back? :/
You need to backup the data manually to your PC and then restore it after CM installation.
Don’t restore the apps automatically using Google account – install whatever you need manually.
How can I copy GApps and CM10.1 ZIPs to my internal SDCard ? If I only can acess to recovery mode? When I try to turn on the mobile phone normally, only shows android logo and exclamation point
no you can restore data with google.
or any other app that uses api
however many of those backup apps dont use fully api they do it directly with litesql which will cause problems.
for example titaniumbackup should not be used
so i recommend sync what you can – if possible to your own server like caldav etc – or if no other choice public clouds like gokgle – be aware that your data will land on the harddrives of several intelligent services like nsa :)))
anyway if you sync all your contacts, mail and browser settings (use firefox they encrypt on the device) theres not much left to backup
you WILL loose your calllogs
you MAY loose your sms
you WONT loose files on your sd card
now all thats left ist data by some certain apps and angry birds.
there are usually built in functions to backup those or cloudsync anyway
for angrybird i simply copy appdata – the rest ; well youve to sacrifice.
personally i only loose the calllogs which i export to csv first for reference.
btw its not a bad thing to NOT backup by google. besides the nsa thing.
almost evry app saves useless stuff so i sync all my data to my own servers
backup those apps manully who needs it (only one or 2) regular sync my sd cards to my smb server and from time to time a nandroid backup just in case (you can extract single files with an app from an nandroid backup)
and simply use batch install of my apps or use appstore on the pc to remote install all 300 of em;-)
that way evrytime i wipe i get a new clean phone without crap databases
only downside is i cant make backups of trebuchet settings or phone settings so ife to redoo all that stuff.
btw for uodate nightlys of the same branch you dont need to wipe at all
