Hello,
I am new to this forum and rooting procces, I've read some threads and didn't understand few things.
So, my questions are:
1. Is it possible to root phone without unlocking bootloader and losing DRM keys?
2. If it isn't,is there a way to backup DRM keys and restore them after rooting?
3. If I am able to root without unlocking bootloader will I still get OTA updates and if I do, will OTA update delete my root status?
Sorry if these questions were already asked in other thread, I was searching a bit and couldn't find any of those. Hope you can help me out.
Thank you in advance and have a nice day
1. Yes it is although you do need some time to do it. It's not difficult though.
2. As soon as you root, you can take a ta backup(which requires a few clicks and about 2 minutes of your time).
3. You won't be able to use Ota (even if you are which you most likely won't, it is recommended that you DO NOT use it).

1.-Yes, the method is called "Downgrading". I go back to 4.4.2 (Build number 314) and use the older XZDR (Xperia Z Dual Recovery). It will temporarily root to install the recovery. When the phone reboots you can install a custom ROM or whatever to get Lollipop with Root and Recovery
2.-After rooting on 4.4.2 you can do a backup of the DRM Keys
3.-Just because you have rooted your phone you will no longer be able to get OTA updates for the Android system itself. OTA will show a random error message and PC Companion will refuse because of the modified software.
Ok, thank you for answers
Is there any 6+ Android build that is pre-rooted or is it better to stick with 5.1.1 rooted?
Alo, I've heard that cam quality could drop after rooting or unlocking bootloader, is it true?

Stick with android 5.1.1 for now.
And yes, cam quality WILL DROP, but only after UNLOCKING YOUR BOOTLOADER. Rooting alone won't hurt your cam quality.

Ok, so I was thinking a lot if I should root or not. I decided to root. So just to clarify some things. If I use comunity root with downgrading,will it keep my DRM keys? If yes, I backup TA partition when rooted and then I can proceed with BL unlocking. Can I restore DRM keys to a custom ROM? Do you have any good custom ROM suggestion for me and is it better to use odexed or deodexed ROM?
I saw also saw this thread, hope it works so I won't be losing any camera quality.
That should be all.
Thank you in advance.
Have a nice day .
If you do NOT UNLOCK your bootloader, you wont lose your drm keys. (this is why after rooting using this method you can actually backup your drm keys, which you MUST DO no matter what).
When you restore your drm keys, you actually RELOCK your bootloader, so you must be on a stock based custom rom, and not using a custom kernel, otherwise you will simply brick your device.
Odexed or deodexed rom is purely personal preference, the difference being that deodexed ROMs allow for more customization (which is not necessary though). Regarding this, it doesn't really matter whether it is deodexed or not, so keep this in mind.
I cannot suggest a rom and I would advise against asking which rom is the best, because it is against the forum's rules.

Thank you for answer. If i use this method will it keep my bootloader locked (Will DRM keys stay on phone?).
Look.
Your bootloader cannot be "accidentally" unlocked. You have to get the bootloader unlock code by YOURSELF. A program wont do it on its own.
So don't worry, even if the method you chose to root the device requires an unlocked bootloader, it will be stated since you have to do it manually.
Plus, rooting a device with an unlocked bootloader simply requires installing a custom kernel(which has a recovery too) and then flashing a zip file that will root the phone.

Thank you very much and sorry for so stupid questions, I am new to this and just want to be sure

So here's my goal, to leave everything stock, with only root (su installed), so I can install a Verizon locked app, su, and perhaps busybox (I installed Terminal Emulator, but virutally no commands available).
1. Why use the one-click method over the method? As I understand it, the just unlocks the bootloader, so I'd need to install a custom recovery, to be able to flash an unsigned zip (su). I'd like to keep the stock recovery. Perhaps the process is to flash custom recovery, su, then restore stock recovery?
2. After I get root, will future OTA updates work? I'd like to not break that functionality.
3. It would be nice if would also allow you to just get root on your phone without dealing with the bootloader.
I've rooted and flashed my old Cliq, and it's nice having root when I need it. I also wanted to play around with setting the button led backlight levels, which via the command line requires root.
wrong section man
Well, perhaps I mis-understood the sections. Seems any questions having to do with roms/rooting go in this section.
Either way, questions still stands, and it seems your the resident expert for this phone.
Forgot to add, from all the other threads I've read, it seems there is/was some confusion as to whether or not the method would all you to flash a new kernel, not that I currently want to do that.
Edit: Since this is apparently in the wrong section, can one of the mods move it?
Edit 2: Thanks Binary100100 for moving this thread to the correct section.

you can flash kernels it is harder what else you need to know
How do I backup the stock recovery?
If I unlock the bootloader, do I need to flash a custom recovery to move forward? Or does unlocking the bootloader allow me to flash unsigned zips?
yes and its hard to backup stock recovery i got a backup all ready
So with an unlocked bootloader, I won't need a custom recovery? Just trying to learn, as it's a bit different than my Cliq.
you do need custom recovery sorry man i cant do much more explaing so busy butother people help you and look around read root threads etc
Well, thanks for the help so far.
If any one else is reading this thread, these are the questions I still have:
1. How do I backup the stock recovery? I know once I load a custom recovery, I will be able to backup the stock ROM.
2. Disregarding any warranty issues, why choose the method or the One-Click method?
3. Once unlocked/rooted, will DRM content still work? Will the Movies section in the Android Market still be available? It's not on my Cliq with CyanogenMod 7.
4. Once unlocked/rooted, will OTA updates apply correctly? Was anyone rooted on 1.36.531.5 and have the 1.36.531.6 update apply correctly?
5. Does the method wipe the device?
Thanks,
Ryan

1. There is no need to backup the stock recovery. Once you flash a custom recovery there will never be a need to go back to stock. If for whatever reason you do want stock then just flash an ruu and you'll go completely back to stock.
2. You MUST use the method to get the unlock_code.bin file to unlock your bootloader before you even attempt to get root access. Once you have your bootloader unlocked you can make changes to the root of your device. With it locked you can only obtain a partial root which will reset itself after a reboot. For example, if you obtain a temporary root and remove a system app (like boatware), or two, or ten (whatever) then reboot they will re-appear. So you MUST have either s-off (not going to happen until an exploit is found and really isn't needed) or an unlocked bootloader. Once you receive the file from HTC then follow the included instructions to unlock your device. NOTE: You will lose all of your data when you unlock your bootloader so back it up first! After your bootloader is unlocked you can obtain root by one of two methods.
a) 1-Click root script.
This simply pushes an app called SuperUser.apk to the /system partition and a su binary file to the /system/bin directory which gives us root. Then download ClorckworkMod app from Market and install the custom recovery. From the app you can select "reboot to recovery" and install your custom roms.
b) Placing a custom recovery in a form of a PH85IMG.zip on the root of your external sdcard and boot into the bootloader. Then update the recovery.
Now with all of that being said I want to make something clear. The unlock method does NOT allow you to use the device for other carriers! You would still require the T-Mobile SIM to use the device.
3. Having root does have some disadvantages. Some roms may effect the ability to watch DRM movies, watch movies from Market, etc. Depends on your rom though. Check with the developer. ALWAYS make a nandroid backup prior to flashing any rom! That way if you don't like what you flashed you can always revert.
4. Okay... well I stand corrected.... this is the ONLY real reason to install the stock recovery. However installing an OTA update will cause you to lose root. Even with a custom recovery and a stock rom... if you receive a notice to install an update it will not work! The best alternative if you really really really want the update and lose all root then flash an RUU, do the update and hope that HTC didn't do anything to prevent you from getting root again. My best advice would be to wait for your favorite developer to update his/her rom with the update that you're trying to flash. That way you won't lose your data (shouldn't anyway) and no real risk of losing root.
With all that being said... I'm moving this to General because it's where all the Q&A's go.
Thanks for all the detailed info. I'd like root (installation of Superuser only) for the stock ROM. I don't plan on installing a custom ROM at this time. If I have an unlocked bootloader, how could HTC block root access? Couldn't I just flash an su zip? Ideally, I'd like to be able to swap recoveries out to apply the OTA updates. I kinda wish they had a code to just give me root access on the stock ROM.
I see the ruu thread, but am concerned about the source of the ROMs. Does HTC ever officially release a complete stock ROM?

If you really want to be able to download and install system updates you will need the stock recovery in step 4.

IDK but I read your questions in a very slow voice like mr. mackey in southpark or something
anyways, why are you so worried about getting OTA updates?
a developer will eventually root and deodex it anyways.
You say you want to keep stock rom, but why don't you try the Custom ROMs which are basically stock ROMs on steroids?
You do realize when you apply an OTA update you lose your root access and there is a possibility that it'll be harder to even have your device rooted in the future.
For example, the mt4g, everybody got happy and updated to the gingerbread OTA, but lost root and nobody found out how to exploit it until about a month later or so.. and that is only by downgrading which is a tedious process that many, who don't know how to use ADB, have troubles with.
I believe the OTA updates comes with new bootloaders and radios, not only the rom, so it will lock your bootloader. (I think) that's what it does to other devices. Who knows if htcdev will work on all bootloaders. just my two cents, if you want full control of your device, unlock bootloader and root it. You can get every OTA update through developers here.

Man, hopefully I don't sound like that. I really appreciate all the step-by-step guides; but, unlike most people, I want to understand what I'm doing, not just run through the steps.

Well, I don't really want to wipe my device at this time, so that probably rules out the HTC Dev method and installing a custom ROM. I asked about the source of the ROMs in the RUU thread, but if the stock recovery would flash them, then they'd obviously have been signed by HTC. If software is available via an official source, why would I download it from a forum? If I can get Ubuntu from Canonical, I wouldn't go download the ISO from an unofficial mirror (or if I did, I'd verify with the md5sum keys posted by Canonical).
Since I am really happy with my device as it is, and the ease of updating via OTA, I didn't want to give that up, just for the couple things I want to do with root access.

Hmm, unless these devices have backup/secondary bootloaders, I doubt and OTA update would flash a new one, as an error during that flash could brick the device. It would seem odd that HTC would promise to unlock bootloaders, give an OTA update that would not work with their site. I'm not saying that it couldn't happen, just seems unlikely. Was the MT4G unlock done via? If it was an exploit to gain root, then I'd understand why they'd loose root.

HTC has updated their bootloaders via OTA on a few occasions. And we know that HTC and T-Mobile (along with other carriers) read these forums as well (shout out to HTC and our wireless carriers) so almost literally the day of an exploit is discovered and if HTC isn't happy with our findings what do you suppose they will do? They will almost always look for the safest way to update the bootloader and keep us from being able to use that exploit. Seeing that we still don't have S-OFF (and may never have it) they are obviously doing all they can to make it more and more difficult. That in itself is proof that they don't want us to have it. So would they push an OTA to keep us locked to S-ON if they can? You better believe it!
I can see them patching a hole that would get you S-OFF, but seems odd that they would take back an unlocked bootloader that they themselves unlocked.
I guess I'm ok with the offical unlock method without S-OFF, if the only things I can't do are flash a new bootloader, radio, or unlock the SIM. Did I miss anything there?
I don't get it, you say you want to use root on the stock roms, and now you're saying why bother downloading a stock ROM that is prerooted when you can download stock ROM that isn't rooted ota? What is the difference? You're going to want to root the ota updates and the developers are already providing it for you. it doesn't matter where you get it, you're gonna use some 3rd party exploit to root the ROM anyways.
You my friend seems to have a indecisive problem. I understand that you want to understand the process, but if you don't want anything to do with 3rd party developing you're in the wrong place. You're making your life very hard.
And i think that's about it about being s-on. It's more of the hardware functionality that is locked.
Think about it as a locked bios kinda... Lol

I don't need to use an exploit to root the stock rom. I can unlock my bootloader direct from HTC, flash a new recovery, and then flash the superuser program. That was kinda my point in asking in the first place... why use an exploit (one-click), when an official route is available?

Well, yeah, you end up at the same place, except instead of using an exploit, I go to HTC to get an unlock code. I'd consider it official since I'd go through HTC to get the ball rolling.

you can try Towelroot as I see Z3TC is supported but I didnt test it on my tablet

There is only one method at this time to get root on this tablet and this method involves unlocking your bootloader after doing a backup of you DRM keys (TA partition). Once you rooted your device with the unlocked bootloader you can reflash the TA partition and the bootloader will be locked again with all DRM keys intact as if you never unlocked it in the first place, but with root. Towelroot is not supported as the kernel exploit that was used is patched since nearly half a year now.
Hey guys,
I own a stock Xperia Z3 Tablet LET (SGP621) and I have never upgraded it, still running stock 4.4.4.
I want to root it and only root (to Lolipop). I have read topics but there are so many and written in strange language for me I have no idea where to start.
I read I could just flash prerooted ROM without even touching my drm keys, right? But then I was not sure how could I do it.
Any help would be appreciated.
Thanks!
There is no method to root the tablet without unlocking the bootloader. The root exploit which most of the guys mentioning in these strangely written topics (giefroot, easy root tool, geohot, blablabla...) is useless now since Sony surely patched it. So to root, you have to unlock the bootloader. But wait, you would loose the DRM keys.
So, it means that you need to make a backup.
But, without root you can't backup.
But, how should you root if you don't have an unlocked bootloader??? And it goes on and on and on and on....
The "trick" is to flash a firmware from another device (not z3 tablet compact) that can be rooted via the exploit. But nobody wanta to use the "other" firmware to gain root. This "other" firmware is only used to gain root temporary so you can backup the drm keys.
Then you likely have to flash back the stock firmware (and root will be lost again).
Now that you backed up the drm keys, you are ready to unlock the bootloader and let the drm keys disappear for a while.
And then you still have to do some complex steps to achieve root on your stock firmware, then restore drm keys (bootloader locks up itself again...), blablabla
TL;DR forget rooting this device unless you are ready to do all these above steps. If you don't understand the steps and are new to rooting sony devices, I recommend you not to root and enjoy the stock firmware. Next thing is that lollipop will come and you could easily update without problems (via OTA). Until then, wait for some magicians/hackers/crackers find a new exploit which can root 2015 sony devices without unlocking the bootloader.
If you want to know if your device (firmware) can be rooted via exploit, try xdualrecovery. It contains the exploit root method. But if you are unsuccessful flashing xdualrecovery, that is because the exploit doesn't work and your firmware is patched.
Sadly, sony devices are nothing like nexus. And including this "afraid of loosing the drm keys", simply unlocking the bootloader might not be a pleasing thing to do.
just to add maybe we don't need to unlock bootloader to root our tablet
we temporarely flash z3 kitkat system to get a rootable core and we flash again z3 tablet compact system before reboot
or so I understood

I would advise not to answer questions about root without understanding the process and/or misguiding people asking for help.
The information you give above is wrong. You don't need to unlock your bootloader provided you downgrade to an explotable firmware.
The thread that details how to root your Xperia Z3 Tablet Compact is this one:
http://forum.xda-developers.com/z3-...to-rooted-lollipop-locked-bootloader-t3083980
1. Obtain root by first flashing SGP621_23.0.1.A.0.167_CE.ftf and the system partition of D6603_23.0.A.2.93_Generic_20GLOBAL.ftf. Then use giefroot to root.
2. Prepare prerooted flashable zip of 23.1.A.0.690 NOBA on your internal storage or external SD.
3. Install XZDualRecovery and now you will have TWRP to install 23.1.A.0.690 NOBA on your SD card.
You may ask any doubts in that thread.

Well, the OP (junior member) mentioned "strange languages". So he/she might not understand all this complex steps. That's why I "let it be" to keep the things easy. If he/she understands these steps then it's good for him/she. But you're right, I lied. And thanks for the clarification and pointing out my wrong information.
Personally, I had every Xperia unlocked without backing up the DRM keys. I never had any disadvantage. I was, however, a little reluctant with the XT3C. That's because I use it as both my phone and tablet.
Still, did it now. No adverse effects. Root is SO much more important than the Bravia engine or whatever. And the camera isn't very good anyway so I don't miss the 'better' quality. It's bad either way
I have mine updated to 5.1.1 and the bootloader is unlockable. However, the rooting instruction is confusing for this version.
I am looking for the definite solution for rooting (if it is required to unlock the bootloader, should I backup TA partition first?) 100% stock 5.1.1.
Frankly, I don't want to mess with Kingroot or similar tools from China.
I'm interested in this as well. Sent for warranty repair and came back with 5.1.1. Looking for recommended way to root and backup TA (though I have the original backup somewhere)

I managed to root the device. Here is a guide:

That's a waste of time. OP has an unlockable bootloader, so he just has to:
- Flash recovery
- Flash SuperSU
- Reboot

Unlocking the BL is still FAR quicker than going through that hellish process for locked bootloaders. It's like trying to juggle with your hands tied to your back, but they're not really tied. Not sure why WE are arguing though. You provided a guide for a locked bootloader, while I gave one for unlocked. What OP decides to do is currently a mystery.

Here is a deal: unlocking bootloader will remove DRM key. The only workaround is to backup TA partition. However, doing such also requires root, so you have to root before unlocking bootloader.
Don't you know your method is no brainer???! But dealing with DRM key is another story.
Hello !
Frankly you should try with kingroot it's not really a big deal it's quicker and don't worry you will not mess up your phone. I did the same on mine, and it's quick...

Kingroot does not work with 5.1.x, sorry.
I still have to rollback to 4.4.x and use dualrecovery method 3.

Okay, so roll back to KitKat, root, backup your TA, unlock bootloader, and then update to 5.1.1 again. You'll then be able to just flash a recovery and root. If you don't care about the TA partition, then unlock bootloader and flash recovery and root.
Be aware that if your device is still under warranty, it'll be voided the second you lose the DRM keys (TA). If you're not under warranty anymore, it doesn't make any difference. If your device has to go into repairs down the road, it won't matter since you don't have warranty either way. But if you have, it's a good idea to back it up.
Also, the X-Reality engine etc. were at one point dependent on the TA partition, but this changed on KitKat, so X-Reality still works on an unlocked bootloader (even though it's really bad).

Here is what I did as mentioned on the post linked on earlier post.
Download the latest ROM with Xperifirm, and 4.4.x ROM found in a sticky on the general section.
Pack the 5.1.X ROM as flashable pre-rooted.
Use Flashtool to rollback to 4.4.x, completely wipe, made initial setup and enable debug, and install recovery.
Install pre-rooted ROM through TWRP.
Backup TA partition and device data.
Unlock bootloader.
Restore TA partition and device data.
Done.
So read this thread [Guide] Safe bootloader unlock, restore DRM, custom recovery, root, bootloader relock
Is this the easiest way to root as it appears complex(sorry not very technically minded).
Also once rooted will I be able to update the tablet or it becomes impossible please?

No, easiest way to root is to unlock bootloadrer and flash custom rom or root stock by flashing twrp, kernel, and supersu.
You need drm keys in case if you want to get back unrooted stock.so do you really need them? In order to restore drm functionality on rooted device, use universal drm restore patch.
With unlocked bootloder, to update custom, use twrp, to update stock, use flashtool.
