JRO03C.I9250JPLH2

Now whats the point here .. ?
how to update the device in this situation

It would support JRO03C... in the 2nd screenshot (below the two videos) in the post u can find that it supports JRO03C (it's at no. 5 under the list of device model & build)

If you use the stock google 4.2.2 images, it doesnt matter what you currently have....you would be replacing it.

if you are trying to run an OTA file, then it might matter....

so i dont need to unlock bootloader or root phone to update it to 4.2.2 .. right ?
i have to simply follow any tutorial to update mobile to 4.2.2 ..

of course u need to unlock bootloader, but don't need to root.
all these included in the toolkit,,,just follow it

what if i unlock bootloader, root my device and then update the device to 4.2.2
is there any problem in it ?

coz i want to install custom roms later on device so i want to root it for once and for all

what option should i select to update to 4.2.2 in gnex toolkit after i have unlock bootloader and root the mobile ?

9. Download, Extract + Flash Google Factory Stock Rom

i have unlocked the bootloader and rooted the device .

now when i pressed the option 9 to update to 4.2.2

it said "if u have rooted the device , updating the image will effectively unroot it"
so what ?
it will unroot my device . ?
and i will be rooting it again after updating the software ?

you should stop.

just stop.

go read what root actually is, then come back and look at your question.

THIS very thing has been asked 100 thousand times in these forums.

that's why I've told you that you don't have to root for updating to stock 4.2.2
