Hello, This is not my primary device. I am trying to backup my buddies data/apps before installing a cm variant. I searched everywhere and i find guides to root with out wiping only for older versions of android. i'd like to be able to root the stock 4.1 without wipe so i can install titanium and backup before unlocking/wiping and installing a custom rom. Any help? is this locked down in newer versions? or did my searches miss a guide. thx a lot.
There is no stock 4.1 for this device. What phone is it cause it's not this one.
crap. I meant to post in the nexus s 4g. mod, can you move this?!

Alright. thx for the confirmation.
Last question, when I unlock the bootloader I understand it will wipe user data. Does it also wipe internal sdcard? I want to know if I should be worried about pulling all the pictures and stuff off before unlocking. thx.

Yes, make a backup of your SD card then do what you want..
If your bootloader is unlocked you can flash custom recovery image and then flash superSU or superuser
Hello,
trying to get root by unlocking the bootloader first (using preload recovery TWRP lastest + tamper bit mod) but I keep getting this error:
booting...
FAILED (remote: Device not unlocked cannot boot)
finished. total time: 0.406s
So I can't preload the custom recovery, is there any way of rooting on this oneplus firmware without wiping the whole device?
Any help would be much appreciated..
Edit: This isn't a reroot, this is first time root/unlock
Did you type fastboot oem unlock?
Your bootloader is locked and needs to be unlocked.
If fastboot oem unlock does not unlock it, then you need to fastboot boot into recovery.
Flash tamper, unlock, and then afterwords, adb sideload SuperSU.

Umm thanks, I could have, but I really don't want to wipe everything, I got everything set up how I want with lots of data..I was looking for a way *without* wiping everything.. fastboot oem unlock will be my last resort tbh.
I thought with such a developer friendly phone there might be a way to overcome this problem

Yeah, I'm in the same boat as you. Unfortunately after all my reading, it seems impossible as CM did it as a preventative measure to secure your data.
I'm going to do a back up of everything and then a reflash to 25R where battery life was best, then unlock and reboot.

Well thats the whole point, the OnePlus One is a very developer friendly phone indeed. Thats why you get the "keys" to unlock the phone with a simple command instead of using a exploit to flash a custom recovery.
On 25R bootloader, it was possible but as of now there isn't a way to root without unlocking the bootloader. You can read the thread here, http://forum.xda-developers.com/oneplus-one/help/root-unlocking-bootloader-t2820628
This is why when people just now get a phone that has the ability to fastboot oem unlock, I suggest them to unlock their bootloaders as the first thing to do.
Backup all of your data and move forward. Best of luck.

if you truly want to restore everything there are apps that will zip up all your data and you can flash in one session after wiping your phone. If you are reloading the exact same software it should not be an issue. check google and playstore for such apps like app2zip
app2zip requires root, which I can't get if I've not unlocked the bootloader, which means wiping everything...app2zip won't help here but thanks for the suggestion

Sorry, but the only way is to unlock the bootloader. You could use Helium backup, also some Apps themselves have great backup functionality.
Yep. Gotta unlock it. No idea why people don't just do that in the first place.

Because most people set up their phone before getting stuck into rooting and the like. Just as I did. I think locking the bootloader is good in theory, but the average user wouldn't know how to brick their phone even if the bootloader was already unlocked, so why do it?

The difference between having a locked and unlocked bootloader is simply flashing custom recoveries or radios/etc. Theres no harm in doing leaving your bootloader unlocked.
The bootloader has to be locked out of the box, I believe its one of the criterias needed to be fulfilled in order to be approved for Google Apps (Play Store,etc). Also, it doesn't make sense to have a bootloader unlocked for average users.
Just unlock the bootloader and learn from your lesson.... either that or stick with stock ROM without root. Yeah it'll set you back because you'll have to redo your phone apps/settings but on the bright side you won't have to do it again because ur bootloader is already unlocked.
You need your bootloader unlocked to obtain root. See http://forum.xda-developers.com/showthread.php?t=2788632 on instructions on how to do so if you're unfamiliar. After once its unlocked, fastboot flash a custom recovery and flash supersu.
Trust me I'm familiar...had none of this trouble on the G1. Out of 5 android devices this is the second time I've had to unlock the bootloader...and the average user doesn't even know what a bootloader is, so not sure they'd be able to mess about with the radios.

Thats because the G1 had a locked bootloader and the only way to flash a custom recovery was to gain a exploit to push a custom recovery. For the OnePlus/Nexus/HTC, we don't need a exploit because we have the ability to unlock our bootloaders. Think of it as Apple's iOS, in order to gain jailbreak you need a exploit to jailbreak your phone which can take a long time for it to happen. Whereas, on Nexus/OnePlus/HTC, we can simply just obtain access to do changes to the phone without having to wait for a exploit.
You keep mentioning average user but a average user wouldn't be attempting to obtain root access for their phone. The average user would just be using his/her phone as a phone and not tinkering with the deeper innings of the Operating System and if the average user wants to tinker with the deeper innings then they should really do their research and learn. There are a lot of good guides on XDA.
Couldn't agree more. There is no need for any exploit with this phone because you've been handed the keys.

That doesn't allow you to root while having a unlocked bootloader. It just changes the bits on whether or not your device has been tampered.
But then again,
This mod will allow you to unlock the bootloader without wiping the userdata as oppose to fastboot oem unlock command.

A little off topic but I unlock my boot loader and root as soon as I get the phone so I don't have to loose anything.

that's what you think, but in my case i was able to unlock the bootloader using the mod, hence rooting was a matter of course. the casual "fastboot oem unlock" command was not effective with my device. so.....
edit: then again, i unlocked the bootloader and rooted my phone while it was still at 30O firmware. i have no idea if the 33R firmware's bootloader is different from that of the 30O or not, that will render the mod ineffective.
It's fine, problem solved, went through the gruelling task of trying to back everything up without root = 40gb of stuff..
Already tried the tamper bit mod...it was stated in the first post (tamper bit mod) and the command screenshot was one of the steps when trying to boot the recovery, it still wouldn't boot because the bootloader wasn't unlocked..so, useless in my case.
Still lost some stuff but I got most of it back. I didn't have this problem on my xperia SP when unlocking the bootloader..if I remember correctly you could root, get recovery and custom rom all without unlocking bootloader. Unlocking the bootloader didn't erase the internal sd either..sure it might have been through an exploit rather than the proper way, but tbh I think I'd rather have that.
I'm not liking this "you've been given the keys" analogy...It's more like you've already settled into your new house and you're given the keys to unlock the front door when you're already inside...it's hassle more than anything.
Hello guys
im looking to root my OPO, but i dont want to unlock the Bootloader or install a custom recovery, just want a method to root so i can install Xposed on the stock CM11S rom, is this actually possible?
Why not just unlock the bootloader? Your warranty isn't affected by it. You lose nothing by unlocking it, and you gain nothing by leaving it locked.

Like @timmaaa mentioned, you lose nothing when you unlock bootloader. Not only that, it is the recommended and futureproof approach to do so. Unlocking the bootloader wipes your phone completly clean. Suppose somewhere down the road you want to try different ROMs, you'd realize you cannot do so without losing your data. So you'r much better off unlocaking your bootlaoder right now.
But to answer your question, no. It is not possible at a simpler level. Unlocking the bootlaoder give you access to all the partitions on the phone. What you need access to specifically is the recovery partition so you could flash a custom recovery and install the SU binaries onto your system. through that recovery.
What others have said, unlock the bootloader there's no problem with leaving it unlocked.
You're given the key to unlock the bootloader using a command. Use it and make your life simple. It's like saying you have the key to your house but you want to get inside the house without unlocking the door. Just use the key and make it simple.

Perhaps you felt like I did, worried that you are ruining your phone or your ota ability.
Unlocking the Bootloader is painless aside from having to reinstall all your programs. Everyone says it wipes the os, but what they don't tell you is that you don't have to dig around looking for the proper version to reinstall. You just type a code, and the phone reboots fresh like a factory reset, ready to go. And installing the custom recovery is easy, and it works perfectly with ota updates.

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.

If he is unlocking he can flash a kernel with recovery and root via TWRP.

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.

If you unlock without backing them up, you cannot restore them, FACT!

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
Hi all,
So I read people are now able to backup TA partition (DRM Keys) before Unlocking the Bootloader.
Keep in mind my aim for instance here is to install BBS (Better Battery Stats app) onto the system partition for full battery stats.
Now my question is can the below tasks be achieved in this order.:
1. Downgrade to an exploitable Firmware (MM?)
2. Backup TA partition
3. UL BL (Unlock Bootloader)
4. Root device
5. Install BetterBatteryStats onto System partition.
6. Unroot device
8. L BL (Lock Bootloader)
9. Restore TA partition.
And where in this list would be best to upgrade to Nougat.
I believe I achieved something similar on my z5c, but it's been a while now since I've wanted to root. But given the recent TA exploits I'm thinking it's time to geek again.
I believe if we can define the above process explicitly, many people would be happy.
As much information, direction, insight, instructions on all of the points above would be greatly appreciated by and for my.fellow XZ'ers :fingers-crossed:
I'm also curious on how to unlock, root and restore
I know it was possible to be rooted with locked bootloader on Z3 but have not seen how to on the XZ yet

No, the XZ has verified boot security (DM-verity). The bootloader will not allow a non signed kernel to boot. Stock kernels will not allow a modified system to boot. Hence you need to unlock the boot for the phone to boot if you change the system partition by just one bit....

I do not know any way of hiding the screen. Also, the DRM fix that is used with an unlocked bootlader is not a full restore of the keys. DRM functionality is restores and to my knowledge it is not 100% the same as restoring the TA partition fully.

However, if the DM verity you mention does what it should then I guess by editing the system partition as I proposed and then relocking would cause a bootloop.
I hope there is a way and perhaps others can share more insight.

It won't work! As @gregbradley said, dm-verity does not allow unsigned partitions (eg modified /system) to be loaded, and the procedure you wanna try will result in a bootloop for sure!
Now that we have a specific tool to perform backup of TA partition, "safe" root came true. So why not to do that?
You can always restore your original TA.img and flash full stock firmware, which will give you a locked device like the never-unlocked one!
Anyway... try it at your own risk!

So who would be best to contact in regards to making this? @AndroPlus perhaps?

Just realised, you won't need to convert anything!
In TWRP, select - Install Image (under Install button on the home menu) and locate the TA.img from there.
Apparently, you might not need to flash stock firmware afterwards, but I would do that if I were you just to make sure everything works cleanly!

No, the XZ has verified boot security (DM-verity). The bootloader will not allow a non signed kernel to boot. Stock kernels will not allow a modified system to boot. Hence you need to unlock the boot for the phone to boot if you change the system partition by just one bit....

Why did Sony do that?
I just dont want to see ads in games and apps.
For these, root was enough. At least my old Z3 phone.
I do not want to open the unlock bootloader, because the device may have serious performance degradation especially on the camera, right?!
Is it possible in the near future to make root without unlock bootloader ?
P.S.: If I knew that, I would not buy XZ.
please stop the discussion on SONY's security measures here

This has been beaten to death in the post Z3 devices fora.
You can read A LOT about in e.g. the Z5 section.
