Assuming you're not rooted, you can boot into a custom recovery without unlocking anything and use that to do a backup and then have that. Keep in mind, this method won't root you and when restored will remove your root but it will not relock the bootloader if that is already unlocked.

"boot into a custom recovery without unlocking anything" how do i do this from mine unrooted nexus s o_0?

[Q] Backup & Unlocking

Sorry for posting a new thread, I searched for about an hour, to no true avail. So, I haven't unlocked my Nexus S 4G yet, but I have made a lot of changes to it. A lot of changes I would rather not lose. So, basically I want to backup, than unlock. Big problem though is that MyBackup needs pro version to store online, and titanium backup needs root (and I'm not unlocked yet)! So basically I was wondering if this process would work:
-Root (no flash to SU)
-Backup using titanium backup
-Flash to SU
-Restore
tl;dr:
1.) Can you root without flashing to SU
2.) If you don't flash to SU, but still have root, can Titanium backup obtain root access?
3.)What are the commands to manually root/where do you enter them?
4.)(A stupid question I know, but might as well ask it in this thread than another one) How do you restore using titanium backup after unlocking/do you need to apply any changes to apps you had installed, or does it just return them all back to their state pre-unlock?

The su binary provides root access. no access to su = no root access.

You can root with out unlocking your bootloader. Then back up.

Never realized you could do that, I'm going to try it soon, and post with updates. Thank you.

Big problem I'm running into. When I am in the console, directed at my tools folder and have the phone plugged in and on the boot loader. I type 'fastboot boot recovery.img' and it says that it is not a recognized command. Any help is appreciated.

That hasn't worked since 2.3.2. It was never intended to work. You have to have an unlocked boot loader to use fastboot boot.

So.. Is there a way to root without unlocking on 2.3.7? Or better yet backup without rooting?

You can try some of the "Gingerbreak" methods out there. They all rely on exploits to gain elevated privileges though so I would guess it's unlikely they will work. Outside of that No. You could try to purchase Mybackup Pro and restore or just forget about it.

BootUnlocker for Nexus Devices worth it?

Hi guys, I found this program "I'm root" my question is, I'd like to close the boot-loader jut for security reasons, but now I've set up everything as I wanted so I don't want to delete everything again.
Can I use this program it seem to be really good.

Waiting for answers.

Yes. I use this to lock and unlock my bootloader once rooted. It doesn't wipe anything.

WOW perfect then I'll do it. Like this if I lose my phone no one will be able to steal anything. (Steal I say xD, they can't do that much. but you know what I mean.)

If you have a custom recovery they can. So make sure you have a stock recovery

Can I lock the bootloader using this app with a custom recovery installed so that when I need to install updates to the rom or flash something I wouldn't need to flash/boot Philz again after unlocking?
Or do I need to flash the stock recovery before locking with this app??

As long as you're rooted it'll work with a custom recovery or stock. Edit, just be careful if you do a lot of messing around on your phone. You may be locked when you wish you weren't

Yes, I get that.. If I end up in a bootloop I would need to use fastboot which will erase all my data.. That's what you're warning me about, right?
To tell you the truth, I'm actually worried about this eMMC failure thing as I have a 1 year LG warranty (not google's). I have seen a few threads where they weren't able to relock their bootloaders before sending it in as the eMMC's write function was screwed up. If I send my device in with a unlocked bootloader, warranty will go down the drain for sure. LG is very strict regarding this matter.
May be I'm thinking too much but my friend had faced similar issues with his HTC One and he had to shell out half the price of the phone to get the mobo replaced even though he had warranty

I'm guessing that if your emmc failed you wouldn't be able to lock using this app. Boot it is an easy way to keep it locked until you need to unlock. It is a good app and it's been on my phone for months. But I usually keep it unlocked

When you say custom you mean, -hammerhead or clockwork- right?
Thanks.

you can have a custom recovery and use that app to lock and unlock your bootloader, just as you can have a custom recovery and lock/unlock your bootloader with the fastboot command.. fastboot oem lock(fastboot oem unlock).

That's why I was thinking to after flashing what I want to, I would lock the bootloader with the app so suppose one fine day my eMMC gets fried, I wouldn't be in trouble as it will be locked.
If I want to flash anything, unlock with the app, flash via recovery, reboot and then lock the bootloader again! Does sound good, right??
LOL, now I'm surely thinking too much

Rootsu was referring to the ability to hack onto your phone not the bootunlocker app. Bootunlocker will work if you're rooted and it doesn't matter if you have stock or a custom recovery

then you dont need the app. after you unlock your bootloader and root it, just boot into your bootloader after and lock it.

But then, when I need to flash a nightly or any mod, I would need to unlock the bootloader via fastboot to access the custom recovery which will wipe everyhting, right? If I have the app, I can simply unlock it without wiping.
Or should I just use fastboot boot on a locked bootloader to flash any mod/nightly??

Wooaaahh?! Thanks for the clarification... Just curious though, why does it not wipe everything when I unlock it the 2nd time? is it because the tamper flag is set to "true"? How does the bootloader determine that it's being unlocked the second time?
Thanks a lot!

As an fyi, I locked with bootunlocker once and then messed up by device where I had to use fastboot commands. It does wipe if you have to fastboot unlock the device again

[Q] Root nexus 5 with Lollipop without losing file

Hi,
I found around the web that is possible root the Nexus 5 without losing file over KitKat, there is a way also with lollipop??
Thanks!

Rooting doesn't cause you to lose data. Unlocking your boot loader does...

I know, but there is a way to avoid the lose of data??

I never recommend toolkits, so out of those two, chainfire. (Wugfresh is a toolkit)
However that said, I would recommend unlocking bootloader, fastboot flashing recovery then flashing supersu from recovery. That way you know what you're doing.

This. Just back up your entire phone (including the sdcard folder) so you are sure you won't lose anything.

I did as I have suggested, all right !! Xposed sin that still does not support Lollipop ..

Root without losing DRM Keys?

Hello,
Is it possible to Root my Sony Xperia Z3 D6603 which is currently running Android 5.0.2 without losing the DRM keys?
I don't want to have to roll back to 4.4.4, or lose any of my files.
I have a pretty slow internet so i'm not a big fan of downloading stuff, I'm just psyched to check out Xposed if it exists.

No, you must roll back to a FW ending in .93 which is KK, then root, then install recovery, then update via a pre-rooted flashable zip
I would not hold my breath for a lollipop exploit. The main reason to find one has gone (i.e there already is a way to get root on lollipop with a locked bootloader)

rooting has nothing to do with the DRM keys
you have to downgrade.
you will lose your data.
you have to download a kitkat stock rom.
No way around this if you want root.

It does if you root by unlocking the bootloader. Doing this wipes the TA partition where the DRM keys are kept

Not if you do not wipe the data partition of flash the data partition from the FTF. You will get a lot of FC's when downgraded but this is not an issue as you will be upgrading immediately to Lollipop anyway

But why revert if he is unlocking?
If he is unlocking he can flash a kernel with recovery and root via TWRP.
Before back up TA.
And after restore the DRM keys.
Easy.

Please read the OP, he does not want to lose DRM keys, hence he needs to root without unlocking the bootloader first.
Also, if you have a custom kernel installed you cannot have DRM keys running, once you restore them using a TA partition restore you relock the bootloader and cannot boot on a custom kernel.

No they cannot unless you have taken a backup before unlocking the bootloader.
There is a thread about restoring some functionality but it does not restore to 100% stock compared to when people have a stock ROM with DRM keys installed, and like I said, READ THE OP, he asked for a way not to lose his DRM keys, not to have the functions associated with them.
If you unlock without backing them up, you cannot restore them, FACT!

Root, backup TA. Save it on your laptop.
Unlock bootloader.
Enjoy a rooted unlocked device with endless possibilities.
If you ever want to have your phone as it was when you bought it, restore TA, unroot etc.

OK, so we are back at the situation the OP asked, how does he root without losing the DRM keys...... Your method said to unlock the boot to flash a custom kernel... That wipes the TA partition and the DRM keys BEFORE you have had a chance to back them up.

You said to root by unlocking the bootloader first, then backup the TA so you are wrong. Editing your post after the fact does not change this, adding the line "Before backup TA" does not make you correct as you have to root to backup the TA.. so when you say "why revert when he can just unlock", that's why.
And finally, restoring the DRM keys after unlocking means you get a locked bootloader, so you cannot boot a custom kernel so you lose root...
The point is now moot, and you need to remember my advice on this, keep it in PM's
