depending on when you backup.. it will restore (app/data state) to what you have at the moment u did the backup..
I know the original update files checks the build.prop for the correct version before updating. maybe due to the driver update ur build prop is updated to 3R.

My nandroid backup dated Aug 15. If i restore will it erase the 3R buiold prop?

if you make the backup before then yes.. nandroid is a complete rom restore.

Me too. I just go to the credit card part, and put again my svc and save. after 24 hrs , fixed

Will the bootloader be lock after restore?

nopes.. nandroid backup does not cover bootloader
/edit
bootloader is similar to our pc bios.. as the word means "boot loader", means it helps you load the boot image. kernel is the boot image and the operating system file is system image (like our windows folder)
backup covers boot.img, system, data, recovery.img and cache. just browse into a nandroid backup folder you can see all the types backed up..
flashing bootloader is the most risky part.

I think it will be easier to do a nandroid restore, root and then update thru recovery. Not going to update now coz my device has no issues ( touch wood ).The 3R binary update also has some fixes. All these infos will assist me when i need to update. Thx so much for yr kind input.

the latest update supercedes 3R..
no prob, actually to play with all these roms.. need to equip yourself with the background knowledge..
actually the method I post also easy.. since u already updated the booloader to 3.41.. just download the file and flash from recovery.. all your data/apps will be intact.

Bro flash bootloader & stock JZO45K with recovery? Filmware to download is odex or deodex? Thx

At last I can buy app using the 25usd credit, haven't use 2days.

successfully installed 4.1.2 although on JR003S... but it was a clean install.... had to reinstall all my apps....

both odex and deodex version available, source
if you already update the bootloader then just backup and flash the rom only.
they recommend flash rom first and then only update bootloader

My bootloader is 3.3.4. Need to flash 3.4.1 & flash the rom.

Besides nexus media importer, is there any other app than can use to read USB or ext HDD otg without root?

Am getting it laterrr my 2nd tegra 3 device!

hope the 32gb model release before i leave dallas
