Root question

So after enjoying the phone for a few days it's time to root it.. from what I've read it seems there is no way to root it without having to wipe data.. this would suck to have to wipe before being able to use TB and get a backup of my apps...
So am I reading this right or is there another way?

Use another backup app Mybackup, Ultimate backup...probably more...they don't need root as TB does

Rooting your phone does not wipe anything.
But you have to unlock the bootloader first before you can root, and that wipes everything on your phone, including anything you have saved on your "SD card". That's why I believe it's best, if you eventually intend to root, to at least unlock the bootloader as soon as you get home with your new Gnex. Before you waste any time setting it up.

Thanks for the info! I just assumed all backup programs needed root.. thanks again!

Yes exactly, I made that mistake as well not knowing unlocking the boot loader wipes everything.

I am in the same boat, how do you save your apps then?

you are right

Whats the easiest way to backup and restore your data?

I know this is sort of a noob question, but I just got the Nexus and I want to be sure before I lose all my stuff again.
1. When i signed into my account on the nexus, it started restoring all my apps from my Incredible.
2. I got my Verizon Nexus tonight, set up everything how I liked it... then I decided to root.
What should I have done before I unlocked the bootloader and rooted it to save all of my apps and settings?
After rooting I returned to the phone and found that everything had been wiped, and nothing restored... Why?
If i wait until the Jellybean OTA update, and apply it, will I lose everything again?
This is frustrating as hell, and I want to know how to keep everthing between flashes.
I know you can nandroid.. but thats of no use to me cause I want to keep the new rom...
Do i really have to use Titanium backup?

Titanium backup is a secure and simple way to backup, imo.

I dont wanna buy the pro version.... any other ways?

I use mybackup pro it works perfectly.

[Q]How to read ext4.win files?

Hey all,
I'm wondering how to read / extract a filename.ext4.win file?
Using Wugfresh's Nexus Root Toolkit, i recently flashed AOKP's JB build 2 to my Gnex, and wiped my phone in the process (intentionally).
The phone works great with the new ROM and all. but I forgot that my data folder also got wiped, and with it all my savegames for various apps.
Before flashing I used the tool to make a nandroid ("Nandroid backup /w Custom Recovery"), and I'm guessing I can find the files I need in that backup. The tool saved the backup as [data/cache/system/recovery].ext4.win files.
I have tried using ext2explore to read the data file, but it doesn't show anything.
TL;DR
How can I read a ext4.win file in Windows?

i thought backups were saved in *.tar.

I don't know how it's usually done, but this tool saves it in 4 "ext4.win" files and a "recovery.emmc.win" file.

As it says in OP: yes I used the toolkit (Wugfresh's Nexus Root Toolkit) to make a nandroid, because it makes it easier (for me) to backup, wipe and flash with a single click.
The toolkit's thread is in a dev section, which I'm not allowed to post in due my "noob" status on these forums.
So that was very helpful, thanks.
I tried Linux Reader you linked to, but still no luck.
I says that the filesystem is not supported.

Twrp also saves nandroids in this extension.
Op: use titanium backup to load up the nandroid (menu -> extract from nandroid backup).

Ah Team Win - that's right, it's what the toolkit uses for backups. Thanks.
I had to get the paid version of TB to use the extraction, extracted only data and it worked to some extend. Some of my games got their savegames restored, but e.g. TinyStation did not - Which is the game I'm most eager to restore the savegames to. I also tried to extract app+data for this one, but it didn't work.
But thanks a lot geoff! =)

Not all games work with backup programs. Which really sucks. But tb is a GREAT app to have, especially the purchased version.
BTW, was it a different ROM you flashed or was it an updated ROM you flashed? If it WS an update, you might be able to restore your nandroid and then flash the update.

Sucky. I emailed the developer asking where the savegames are stored, so let's see if they'll be able to help.
Yea, TB is great - definitely my backup app from now on.
It was an updated ROM. I flashed from Kang's JB build 1 to build 2.
But yea, restoring the nandroid and flashing without wiping is the next step, but it ****ed my phone last time, so I was hoping to avoid messing around with it again.
Actually I might just have realized why it didn't work the first time. =)
I'll give then app dev 'till tomorrow, and then I'll restore and reflash.
Thanks again, geoff.

Could you restore the nandroid? I made a backup using Wugfresh tool and now I can't restore the files. The files are like yours, not disc image. I hope you can help me restore the backup. Thanks.

Titanium Backup.

Been some problems with titanium back up when flashing new roms, see galaxy nexus development threads for some examples, if you want a relatively failsafe method that stores your apps off phone you can use a file manager like astro to back up all your apps into apks then drop the backups into a folder on your computer via usb, along with any media or data you want preserved, then reload after fully wiping phone and flashing new rom, you might have to download a file manager to install the apks if rom doesnt have one. Gather you have a custom recovery installed, dont forget to update it prior to flashing new rom so you can recover if all doesnt go to plan. Good luck

If you're interested in using your PC to back things up, you may as well give apk batch installer a try: http://forum.xda-developers.com/showthread.php?t=1531880

If you are using the latest version of titanium backup, you have the option of creating flashable zips of all your apps with data included. Tried it a few times and it seems to work flawlessly for me. The key is to avoid restoring any system apps. I have about 70+ apps to restore and setup. Before it would take me an hour or two, now is done in about 10 minutes.

That was very useful. First time to know such feature. It seems only available if you donate. Thanks anyway

Titanium backup is useless unless you actually have the pro version. Pro version makes it all one click, set it and forget it. Definitely recommend it for any custom rom flasher.

[Q] Google Play Edition ROM

I've been checking around and I haven't had my question answered. Is there a Google Play Edition 4.3 ROM for the M919 that is strictly stock (what would come if I bought the phone) and that was able to receive OTA updates? I flashed one from galaxys4root.com but I don't know about OTAs on that one and I had horrible battery life.

We will never be able to receive official otas from Google on Google edition roms. Not unless the signing of custom Odin tars becomes possible and we're able to repartition our phone to be exactly like the Google editions. But even then, repartions are extremely risky and have a high chance of bricking.

Thanks, I'll stick to stock then as I hate losing my data after each upgrade, unless there's a ROM you recommend? (That would let me update without deleting data).

If you don't want to lose any data, you should nandroid and try any touch wiz based ROM.

I beg to differ. If your TiBu folder is on your external card, you have to go to preferences->set backup folder. Back up to your root directory (or I think you can go in sdcard1 in the previous dir) and select external_sd->TiBu backup folder. Set that as the backup location, back out of it, TiBu will reload the data, then you use it like normal.
