thanks efrant, flashed back to 4.2.1 and everything updated like you said!
I guess i must have missed something the first time around.

Much appreciated, thanks again

Missing Developer Options???

Thanks efrant great post, worked like a charm.

However after i flasheh to 4.2.2 I cannot find "Developer options" under settings, am I blind or did they move it, or do I have to do something to add it?

Please answer swiftly need it to backup and root

This was so in stock Android 4.2, IIRC.

2) This method is EXACTLY the same as a "return to stock" method. If you follow this (including the optional steps in part D), you will be fully stock.
3) yakju is a generic build, meaning no specific localizations. There are reports that yakju does NOT contain certain dictionaries (such as Norwegian, Swedish, Danish, and possible others). So, if you currently have these dictionaries, and want to keep them, do not flash yakju or takju.
4) MacOS-specific instructions: a) replace fastboot in the steps below with ./fastboot-mac and b) no drivers required.

FYI I can confirm that Danish is in the yakju 4.2.2 package, just if anyone was wondering!

Happy JDQ39 user

Thank you for making everything so clear. I took a long time reading everything through, followed the n00bs instructions for my yakjuxw, and am now a happy yakju user

hi efrant and the other folks! ;P

i flashed the 4.2.2 factory image ,flashed twrp 2.4.1.0 recovery.img and rooted it , all via fastboot/adb. everything works!
in another thread you said that the 2 files(script and patch file) which rename my custom recovery DO NOT exist in the factory image from google( yeah i can'T find them in the /system folder^^). ( i rebooted my phone several times and still got my twrp recovery, no stock recovery overwrite it). so does it mean i'm fine, don't have to worry about losing my custom recovery and can start flashing custom roms now?^^
thank you in advance.

thank you in advance.

those system files exist when you receive OTA update only. since you flashed 4.2.2 via fastboot, you are ok with your custom recovery

i've got another question, sorry. -,-

i searched in this thread about installing the busybox after i rooted my device. it already has been said that it isn't necessary. some apps may need the busybox to work or get acces to some directions in the system. efrant does not mentioned in the OP that we need to install it, after we root our device.
so if an app ask for the busybox to be installed, which file/zip/app do you guys use?
are you simply install the busybox app from stericson on google play? ( that's what i found so far, but some toolkits like the galaxy nexus toolkit use some other busybox files, which don't create an extra app on your homescreen)
thank you.
