why unlock bootloader - Verizon Samsung Galaxy Note II

1.how do i backup my Verizon Samsung note 2 keis does not work
2.what exactly does mean if you unlock the boot loader it seems i need to do this so i can use the backup option int the galaxy note 2 toolkit
is there another way to backup or is this the only way? im on stock rooted I605VRALJB. all i want is to be able to do is a backup throgh keis or equivalent
anyone recomend a lockscreen like noled or a simple notification/nightstand clock app/widget
thnks

1. The best way to make a backup requires an unlocked phone with a custom recovery. Then you can make a full image of your phone in it's current state. Very handy.
2. Unlocking the bootloader gives you access to low level parts of the phone, things outside of Android itself. It allows you to install and tweak parts of your phone you otherwise couldn't, like the kernel and the recovery. This means more customization like different ROM's and overclocking capability. If you have any interest in modifying your phone I would recommend unlocking your bootloader, but only if you're comfortable doing it. It's so easy that anyone could do it, but still it's always your responsibility if anything happens.
No idea for your last question.

ok so i need to unlock the boot loader to be able to do the backup right? Then do i need to secure it as in change a root password or is that more of a you can brick your phone?
If that is what i need to do is it hard to undo since it is not recomended to use odin again except to go back to stock which is fine since i dont want to mod anything except getting root so i can tether and being able to do a backup. by the way the unlocking process will it erase my current setup? or will it stay the same since im already stock with only mod being rooted? any links to videos showing how to would be nice thanks. yea so easy a cave man could do it but the internet can prouduce a better caveman/noob.
looking to get another verizen note 2 any idea of where to get one cheap?

[Q] Best Backup Pre and Post Root/Bootloader Unlock?

Cannot seem to find the answer for this specific device. Will have the ATT USA version of the HOX+ and want to know:
What is the Best Back Up App to get before rooting or anything like that, something that can be found in the Play store? Obviously would want it to backup the basics like calender, contacts, email accounts, etc. Also though, need a backup app that will backup installed App Data like say my game progress for Dead Trigger. I'm reading that once you root your device all App Data is erased to scratch, would hate to invest hours into an app only to have to start all over once Rooted when it does become available for ATT USA version.
Then once i am Rooted, what is the best Rooted Backup App to install that will backup everything above and anything else i would need before unlocking Bootloader and flashing roms?
Seems there's unroot backups and rooted backups but hundreds on the Play store and hate to find out the hard way which ones actually work and do what i need and which ones don't.
Appreciate any help on this and hope soon there will be stickies in this thread explaining such things to Androids Newbs like me so once this device is released tomorrow you guys don't get countless threads started like mine. Thank you
Is this right?
Upon doing more research online please correct me if i'm wrong here. From my understanding this is the process needed to flash a custom rom:
1. Root your device. Rooting actually does not delete any data or files but virtually "unlocks" (almost like jailbreaking Ios) your device for further access/tweaking abilities.
2. Now that i am rooted i can install titanium backup (is this the best rooted backup, see it mentioned by you guys a lot here) and this rooted backup app will backup virtually everything on my device including app data.
3. Once rooted, i can now install custom recovery (what exactly is this and what does it do?). I'm guessing custom recovery is needed for unlocking the bootloader incase there is a problem custom recovery will recover your device (hints the name custom recovery)?
4. Now i have my device rooted, everything including app data backed up with titanium backup, custom recovery installed, now i can unlock bootloader. Once i unlock bootloader i will then need to restore my device with titanium backup. Now my phone is basically fully unlocked (fully jailbroken) and can now flash any custom rom available for my specific device (ATT HOX+ USA model)?
I see something mentioned about ADB but do not understand what this does or is used for? It seems it is another way of backing up the phone but if so, where is the backup file saved and used for exactly?
Just trying to figure this all out guys, please be easy on me. Trust me i've been researching and just trying to put all the pieces to this android puzzle together here, newb to android and first android device (very excited and just want to do it all right and not have issues of course).
If i'm missing any steps or have them out of order please let me know. I understand there is no root yet for this specific device but just saying if everything was available the steps i laid out is what i would do?
Thank you in advance for your patience and help, greatly appreciate the community here and all you guys do for us.
Sorry one more thing. Once i am rooted, unlocked bootloader, flashing custom roms having a great time. What exactly do the warranty people look for if i need to send my device in for replacement under warranty?
Do they void it if my device is rooted, or unlocked bootloader, or both?
If so, is root and or bootloader unlock reversible if i needed to return my device under warranty for say a hardware issue?
I'm sure i can flash the stock rom back so the warranty people won't see a custom one on the device but do they look for Root or Bootloader?
Just trying to cover all my bases here, thank you.

[Q] How to remove bloatware from stock

I'm about to get the DNA and was doing a lot of reading on S-Off/On, unlock, root and pretty much, I think, know what I need to do. But, not to f-up, would like some validation and corrections from you guys.
So, once I get the phone the very fist thing I will do is unlock as it will cause everything to be deleted, so no point in setting anything up. Correct?
Once unlocked, I can setup and use phone and root later, but I want to remove all the VZ crap, so, I'll probably root right away as well.
From here, how do I remove the bloatware as I want to stay stock and don't want install any 3-rd party kernels that allow system read-write while booted yet. I'm guessing that there are probably "unbloat" zip files that can be flashed via recovery, is that correct?
I haven't research custom recoveries yet, so wont ask but any volunteered information is welcome (which one, any issues to be aware of)
Thanks for your help.

You can't change any system permissions without being rooted. You will be stuck with anything that resides in system/app. There are some other methods that run an exploit without a permanent root for different phones, but HTC is very strict with what they allow. Alternatively, if you do plan to root and flash then you could use my simple guide for everything else: click here
You will have a lot more fun and better results with performance and battery if you do root and flash. With the simplicity we have now for unlocking this device you would be stupid not to go further
That was my sentiment exactly - root is required to do any modifications/bloatware removal. I might have not been clear when stated that after unlocking the bootloader I can use the phone and root later. I understand that until rooted no changes can be made to system.
Nice Full Gide you have written there, btw, uppon2.
If you delete bloatware while the phone is booted in android the changes won't stick unless you have a writeable kernel. You can use a script that will wipe the bloat in adb instead of flashing a writeable kernel.

[Q] Safestrap on unlocked bootloader

My phone boot loader is unlocked .installed twrp but I want to use safestrap. I like custom rom but only for tweaking .. so I wanna still use stock rom for normal use.as far as I am read, the only way is safestrap but can't be installed on my samsung galaxy note 3. So is there anyway I can achieve this?? Please. Tell me if possible. I would appreciate it.or is there any other way for using multi rom (2nd rom on sd card or internal) ?? Model no. Sm-n900. I know the credit goes Hashcode. Can't I just get safestrap recovery img, zip, tar anything .Just like normal custom recoveries.or can someone backup recovery.img and upload. Does it work that way? I have the firmware file so I can simply restore it. Just in case of _____.I also have backup.
Looks like you are out of luck. Doesn't seem like any developers have taken it upon themselves to get any dual or multi-boot options working. Only thing would be just do to nandroids to switch between. Not the best option, but better than no option.

I thought it is possible cuz even on locked bootloaders its possible. So why not on unlocked ones.if any developer, think of this try to make this it can be easily done. I think...
Sure, theorectically it's possible as there have been a handful of Samsung devices that can dual boot with the help of a custom kernel, but I couldn't find anything, here or otherwise. that they have for the N3.

Just want root access; happy with stock ROM. Possible?

ok so please be gentle here, coming back here after 7 years, from old Windows Mobile days!
I am a newbie to Android and want to root my Z5 compact. The only reason I want to root it is to enable some apps like Greenify and GSam battery monitor to work with all their features enabled. I do not want to flash a new ROM. I am happy with Sony's stock ROM.
Is it possible to get root access without installing / flashing a new ROM?
I have searched the internet but people talk about flashing every time I read about rooting. Then I also saw this thread: http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605
Lots of geeky stuff there which is fine, but again, it seems to talk about flashing the ROM, which I really do not want to do or do not see the need (yet).
Unlock boot loader:
I see that Sony lets me unlock the boot loader from their dev site. I am willing to unlock the boot loader. (Not sure if I want to do that first. Maybe unlocking BL is all I need?)

The only reason to use that guide is to backup ta keys for whatever reason you'd want to do that.
If you're after root on stock ROM the single easiest way is to unlock bootloader, flash twrp 3.0.2, flash xpower 3.0, and that's it. Solid marshmallow with root goodies. Xpower has everything and is deodexed and ready for xposed framework.
just a little more clarification please?

I do want xposed framework though.
I wish there was a simple straightforward answer

Twrp is your recovery,you flash through fastboot, xpower 3.0 is the ROM, just a pre-modded stock ROM with options of xperia x addons. Use lite and stock kernel for xpower and you'll be set.
still a little confused

Ok thanks! So my understanding (so far) is :
We "must" flash a ROM in order to root a phone. Did I get that correct?
Since I said I like the stock Sony ROM, you recommended the xpower 3.0 ROM.........but the point is.....I still have to flash ROM.
A little confused here...
I am a systems engineer (my day job). In Linux or Windows OS, if we want root access (to run some software or a low level command, like partitioning a disk etc), we either run SU command and put root's password OR right click and run as administrator......
We never have to install a brand new Operating System to get root access.
Just a total newbie question.....Why do we have do install a whole new OS (flash new ROM) on our Android phones to get root access?

Android is Linux, to gain root in the ROM you have on your phone currently all you need is an unlocked bootloader to run SU, but then you'll be left with a phone that still needs a customized kernel to keep root and a DRM fix for the camera. Xpower 3.0 is that package.
You could really benefit from reading more. Google up on dm-verity and Sony Ric, and fastboot/adb for a little better understanding of what you're getting into without a pre compiled ROM. Messing around with any Android you'll have the majority of the same steps, unlock bootloader with fastboot, flash Supersu, customized kernel.. Etc
Why use a stable compiled ROM?
Let me list down and explain to you why it's best to use a stable compiled ROM. But first you need to understand these few things before you decide to unlock your bootloader and root.
Before Sony Z models kicked in, every rooted Sony device are still able to retain all the features that came together with the phone before it was rooted. When Sony introduce the first Z model, they start to create these things called DRM keys. DRM keys are unique algorithm (i guess i should put it that way) which is attached to every phone the same way an IMEI number is attached to every phone. In short, my DRM keys cannot be used on your phone and vice versa.
DRM key: It's a unique algorithm that holds all the unique features that an unrooted Sony phone boast such as camera quality, X-reality, High Res Audio etc etc.
The moment you unlock your bootloader, that's the moment your DRM keys will be lost. But don't panic, the wonderful devs on XDA have prepared a tool to backup your TA partition (a partition that contains your DRM key) for your own convenience if you want to relock your bootloader.
Then recently Sony/Android come up with new features called Sony RIC and dm-verity. (You may Google what these are all about but to my understanding it is placing limitations to people who root their phones to meddle around with the system settings of thier phone)
With all these "hurdles", it have taken some time for devs here to find a work around and like every fairytale ending, they manage to find a way.
Now you're wondering if you can actually root without flashing another rom. Good news for you: you can! There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting.
.. But ask yourself what's the point of going through the hassle of rooting and your phone is not tweaked for performance or for theming purposes?
That's when people flash roms and in Z5 compact's case, XPower is the best rom there is. It gives you all the performance tweak you need to make your phone lag free, it has a lite version that removes all the unnecessary system apps you can't delete without root, it gives you an option to add themes and framework from Xperia X with all those work around in place.
For your second question: why is there a need to install TWRP?
TWRP is a recovery tool which is a need for all rooted phone. It's also a tool for you to backup and restore your current rom so that you can rollback to the last working configuration if your phone went into a bootloop etc. Plus i believe all these guides require you to actually use TWRP to flash the SuperSU to successfully root your phone.
I hope this explains your doubts.
Thanks a lot but...
firdyRAY, thanks a lot for the comprehensive reply to my questions. And yes, it has shed a LOT of light on my doubts.
I googled Sony RIC and dm-verity:
I could not get find much on ric
Dm-verity seems to me a way to check if the boot image has been modified from the last boot, and if it has, stop from booting. Sounds like a good idea until we understand that to flash a ROM dm-verity needs to be bypassed/turned off.
So to compile what I have understood so far:
By unlocking bootloader, you lose DRM keys. There is a way to backup DRM keys which are in the TA partition, but this is to be done BEFORE you unlock bootloader. Good that I have not done anything to my X5c yet.
The next steps for me would be to look into XPower 3 ROM…which I did and here is what I found out:
http://forum.xda-developers.com/z5-compact/development/rom-xpower-v1-0-aroma-debloat-custom-t3371100
First, what's up with the scary looking warning in RED right at the top of the first thread. I did read the OP and the second post, I did not see anything in there which IF I missed will cause my phone to explode! That is probably posted to make noobs read all instructions, right?
Second, I do not see any step in there to backup the DRM / TA partition. I guess the dev is assuming the phone already has lost the DRM, right? So I gotta find instructions on how to backup DRM / TA
Then I searched for problems in this ROM and seems to me that the fingerprint sensor is reported by many to be not working and/or buggy. I rely on the fingerprint sensor day and night. I have many apps which rely on that, like lastpass. That would be a major deal breaker for me.
So going back to stock ROM option…I remember you said "There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting."
Could you please post a link to that?
Thanks again!
I think this is a pretty great thread rajdude. It's getting people to spell out a lot of information to noobs like us that it seems most posters have taken for granted over time.
I'm a complete novice at all of this. Sort of gleaning information as I go along, but I used this guide: http://twigstechtips.blogspot.hk/2016/04/sony-z5-compact-root-without-losing-ta.html?m=0
Along with this guide: http://forum.xda-developers.com/xperia-z5/general/guide-rooting-unlocking-bootloader-t3354307
The first guide is pretty basic step-by-step instructions. It unfortunately occasionally kind of skips over a couple very small things (that will be clear as you go along), or occasionally words things in such a way that might not be completely intuitive, but maybe that's cause I need things explained to me like I'm five sometimes. Any time I might have had a question about something in the the first guide, I went to the other and found the answer. It didn't take me long to get the gist of the whole thing though, and overall, it wasn't as scary as I thought it was going to be. It'd be fantastic if someone created a video walkthrough, but so far as I know, no one has done that yet.
The guide will help you back up your TA Partition where your DRM keys are stored, unlock your bootloader, root your device, and then restore your DRM keys. In order to do this you need to downgrade to Lollipop (if you're not already on it), and then upgrade back up to Marshmallow. It will also install TWRP (which I had no clue was installed until I went into "recovery mode" by pressing UP when I saw the LED flash yellow during boot). There may be an easier way to go about this whole process, but this is the process I used.
Before jumping into anything, I'd hold off until you heard more from firdyRAY or someone more experienced. They may look at the guide I linked and be horrified.
And yeah, I haven't installed xpower yet for the same reasons you haven't. Sounds like there's even an xpower 4.0 that was released recently, but still seems kinda buggy. Being rooted with stock I've been able to give Greenify access to root. Install Adaway (which was worth getting root to begin with). Install sound/music mods like DiVA-X, Viper4Android and Dolby Atmos. Install Titanium Backup. And make a few other minor tweaks (that I've since reversed). I still don't know much about custom ROMs and all that jazz, so I'm holding off until I get more understanding. I'd love to install the xpower ROM (when the bugs are worked out), and maybe some sort of sound ROM. I also need to get more understanding on some of the other vernacular like what exactly a "dirty flash" is.

sony ric is a layer of security for sony roms so that they can protect nfc and fingerprint stuff. samsung and htc have there own variants as well.
yes lol the big red lettering is there to make you read, although hes not far off on the melting your phone part, the s810 is ridiculously hot.
the xpower thread doesnt not include the drm backup instructions because: 1) you need bootloader unlocked to flash it. and 2) because it includes the drm fix in it so you dont have to backup your ta keys.
the fingerprint sensor bug is on any bootloader unlocked phone, the hardware fails after x amount of hours and requires a reboot to work again. xpower is a stock rom, the only thing different is its pre-rooted, de-bloated, and deodexed for xposed to work. we have a separate thread for the fingerprint sensor bug and its been solved.

Sony RIC main function is to disable /system write even you got root permission(you still able to do /system write but after a reboot will restore to original). There is a workaround but very trouble, TWRP recovery file manager can bypass Sony RIC(it works in the old day for me, not sure about now). BTW, all 3rd kernel should be disabled RIC nowadays. For any regular computer, there is no hardware or software lock to prevent you gain root access in linux but there are many such trouble stuffs in the android world... lol
I'm running XPower 3.0 Full as a daily driver since June and been very happy. Battery life, stability and speed is good.
Please note, that you MAY lose your warranty when you lose your DRM keys. That's why I didn't unlocked my phone before there was a way to backup TA partition. Now I'm after warranty repair, and before it I was able to fully restore stock ROM with DRM and all features fully functional. In my country, there is only one Sony approved repair center and they check DRM keys before repairing anything - even if it's mechanical fault.
When I had Z1c in KitKat days, it didn't had dm-verity and Sony RIC. It was possible to gain permanent root with bootloader locked, so I was happily using stock ROM and kernel. In Z5c case, first thing I tried was to do the same and it was possible (just backup TA, unlock bootloader, and flash TWRP with patched kernel (dm-verity and Sony RIC disabled) to begin with), but going XPower way was much more confident - I didn't had to think about removing every bloat app. I just flashed lite version in June and I'm using it till this day without any problems at all
Another thing is that you lose OTA (Over-The-Air Update) functionality when you unlock bootloader and disable Sony RIC and dm-verity. Updating to newer versions of firmware, even on stock ROM is problematic when you modify it.

It's simply not possible. If you are rooted you can't apply OTA updates and neither should you.

That's just what I wrote - just put it in another words

Need root can't lose data.

I have a vernee v2 pro. And since I have got I loved the phone but there was never a good way to root it. Recently I found out there was a twrp for it and I could finally flash it and get root on this thing. But there is a problem. I can't unlock the bootloader without losing my data. There is a specific work app that is very poorly made and can't be backed up asnfar as I can tell. So is there a way to unlock the bootloader without reseting my phone? Cant I just make a backup of the phones complete storage? (like trough adb as though I was making an iso of my phones flash to then flash onto it). I would make a full flash dump. Unlock the bootloader and then flash it back. Is something like this possible?
