Hi!
I updated to 4.1.B.0.587 and tried rooting but it's impossible. The only method I found involved flashing an older kernel from other phone model, but all except one can't be flashed because Flashtool pops an error. The ST18i kernel is the one that can be flashed, but on restart it gives a black screen. The only way to get out from there is to flash back the original 4.1.B.0.587 firmware for my phone.
Any idea what to do there?
If not, I'm aware you can unlock the bootloader and install whatever you want. I understand the bootloader unlocking part (and I have "Boot loader unlocked allow: yes"), but then how do I root exactly? I see threads here where you can install a custom (already rooted) kernel, but I'd like to root the stock kernel/firmware. I need CWM I believe. Can someone post the steps how to do this?
Thanks
Btw, I have the America variation, wt19a. Does that change anything?
You can unlock bootloader and flash a custom pre-rooted kernel and that's the only way you can get root without downgrading your phone. There is a extended stock kernel in dev section which is just a rooted, CWM installed stock kernel. You can try that after unlocking your bootloader. It's always better to use a custom prerooted kernel because by installing it the root and CWM is permanent but if you downgrade, root and install CWM via x-parts, it is only temporary and you can easily lose the root by flashing some mods itself.

Thanks, I just got stock root with .587 with this guide. I didn't look into it at first because it was meant for .431 (this thread has it the same). But it works like a peach. I used Xperia-ROOT.rev4 and made a "factory reset" after the process. Ended up with a fresh .587 rooted, Superuser app survived the reset. Installed SuperSU from market and deleted the Superuser apk from /system/app. Everything looks good and feels fine.
If anyone sees this, forget downgrading if you have a LWW, use that guide.
Btw, the ghost of GB haunts me... my last phone was a Galaxy Note and I had to go back to GB, wipe and then install an ICS rom (because of the eMMC bug). Now I get a LWW and the only way to root is falling back to GB, root and install ICS. **** :silly:
(SOLVED)
Hey guys, first time root here. HTC One AT&T 32gb
I was succesfully through the process, used a guide on htconeroot.com to go through all of the steps. Everything went just as expected and I had root access through superSU (was able to install and use root apps, such as Titanium Backup and AdFree). I used Root Manager to flash Clockworkmod because I saw a ROM I'd like to use in the future that only supported that custom recovery. After succesfully flashing that, I then made a backup using Root Manager. Everything was successful and expected, but upon reboot into my stock ROM from the original unrooted phone I had apparently lost SU binaries and root access. Also, ROM Manager (v5.5.3.0) cannot find any backups.
I tried reflashing superSU from the original rooting guide (UPDATE-SuperSU-v1.65.zip), and while it was successfully rooted, I still did not gain root access. I had read through some forums that using the stock ROM that came with the phone might lose root because of the stock recovery, but not sure if that is what happened. I have not installed a custom ROM on this phone yet.
Any help would be appreciated.
UPDATE: Solved, had to select "No" when rebooting from CWM on stock recovery option
I have trued to read and search the forums, but I haven't been able to figure a definitive answer to this...
When I flash CWM on my S2 using Odin, does it root the phone ?
I usually Root (with framaroot), Flash CWM, Flash CM 11 nightly, Re-root using framaroot.
But Can I just do : Flash CWM and Flash the CM 11 nightly ? does it auto root ?
What do you mean, 'usually'? Why is it that you can't just flash each new build of Cm11 from the previous one? Why do you need to re-root in the first place?
When I rooted my phone, rather than using a one-click such as framaroot, I flashed a kernel (siyah in my case) using Odin. That gave me CWM and root. That cuts out the step you're trying to to eliminate, if I've understood your question correctly?
I'm not sure in answer to your direct question, try it and see. Hopefully the alternative method I just gave you makes it a little quicker though
Edit : you could, if flashing CWM only doesn't give you root, just flash SuperSU from there and then continue.

Well mate your question is tricky to understand :cyclops:
1. NO installing CWM wont root your device requires another process (such a framaroot)
2. Aftrer installing CM 11 you dont have to re-root the mobile because CM comes prerooted with superuser !!
3. if you had already managed to install CM 11 think that you have already rooted your mobile
just for typing the 3 points my head spins in short no need for rooting after cm 11 ....and NO cwm wont root your device

Thanks for taking the time to reply.
Why do I have to install CWM if I'm already rooted ? Can't I just framaroot then install CM 11 ?
Can I do a CWM, Cyanogen install without rooting ? Since CM already comes rooted. So jut CWM using odin, then CM install ROM. ?
Other question, Let's say I root, flash CWM, flash a ROM (any rom), can I be unrooted after that and have to reroot again ? Or do ALL roms come pre rooted ?

CyanogenMod comes rooted. Also, the default recovery on CyanogenMod is CWM as well, so you can boot into recovery with volume up + home + power and flash a new build from there. You don't even need to use framaroot or flash CWM using Odin...
And yes, most (almost all) custom ROMs should come rooted unless you're flashing stock Samsung ROM through Odin. Besides, if you're flashing something in recovery, I don't think you need to be rooted.

Just to make sure that you understand everything i'm segregating your questions
1.Why do i install CWM when i'm already rooted?
Rooting is a process which just gives your overall control to your device, but just rooting wont make you eligible to flash any ROMS. Now when your install CWM (Clock Work Mod) its a unique type of recovery which enables your to flash Custom Roms. Your ordinary stock rom (your samsung firmware) also does have a recovery (stock recovery) which cannot penetrate into system files. So CWM is a must to flash roms !
Can i do a CWM and flash Cyanogenmod?
Absolutely NO!! Just because CM comes prerooted doesn't mean that you can flash CM without rooting.. CWM requires root to flash and change system files. For instance your are in Stock Samsung Firmware not rooted you just install CWM flash Cyanogenmod and you'll end up in a bootloop or softbrick. Since your system didnt allow files inside coz no ROOT!!..In the other hand if your already running Cyanogenmod (any version) you dont have to root nor flash CWM because they come prerooted and preinstalled with CWM.so you can flash on the go
Let's say I root, flash CWM, flash a ROM (any rom), can I be unrooted after that and have to reroot again ? Or do ALL roms come pre rooted ?
Well cyanogenmod has an inbuilt function to disable root and most of the Roms comes with it now it can be found in settings >developer options> and root access...but not all roms im assuming. on the other hand yes some roms never come prerooted such as (omni rom 4.4.2) where you have to flash superuser to get root. But as i said incase of all prerooted roms there is an option to disable root
hope this helps you understand about rooting and cwm :good:
Thank you both for your answers, I understand much more now.
BUT
Last two answers are in conflict. They say the opposite.
which one to choose ?
Sorry to bother you, I really used search functions, but there remain questions:
I have a SGP511 with build 23.01.A.4.30. I would like to root it and install a custom recovery (Philz DR). For the moment, I do not want to unlock my bootloader for warranty reasons. After doing all this, I would like to have my tablet back in the state it is now (4 user accounts with different apps).
It seems I can't root this Kitkat 4.4.4 stock rom, I need to downgrade before to 4.4.2. To install Philz DR it seems I need root, because the installer option 3 "Installation on unrooted ROM using TowelRoot" cannot work on Kitkat 4.4.4. So the correct way to do seems to me: make a downgrade via flashtool (to FW .402), install Philz DR, root and upgrade back to 4.30. So far, so clear. Now to my questions:
- To save all my apps and data , I should make a nandroid backup before, as it is recommended in every howto. But how could I do this on a non-rooted device with stock recovery? All I see now is to use helium backup (which is not comparable to a nandroid backup, I suppose this will not backup all apps in all user accounts).
- Can I skip the downgrade step above and flash a prerooted 4.30 build directly via flashtool ? Will it be possible to install Philz DR after that?
- There are several prerooted ftf files with suffixes like [VMo RU-UA-KZ] (I suppose Russia-Ukraine-Kazachstan). I can't find any ftf with a german version.
Any help is highly appreciated.
Matthias
Edit: for backup, it seems I could get it using an adb backup or Holo. (?)

I'm quite new to rooting and flashing stuff on Sony devices, coming from Nexus, I find the limitations quote annoying. Anyway, you cannot make a nand backup without a custom recovery. Also, going from different versions of Android like you're going to do (back and forth between version) might screw something up. So a full is advised.
What I would do is: Upgrade to Lollipop, make sure it backs up everything on all accounts, go into games and let them sync with Google games, so that you have saved games in the cloud.
Then downgrade to 4.4.2, root, install recoveries, flash prerooted lollipop. In the first boot up, there's an option to restore data from a previous device. Choose the Z2 tablet, and sync the apps. Do this for all the accounts. You'll have to log in again in the different apps.
Read something over at Sony devices general on Xda about a root method called "Kings..." the last part of the name I can't remember, but it's easy to find, and might be worth a look
Edit:
Found it, it's called Kingsroot, check it out here: http://forum.xda-developers.com/showthread.php?t=3107172
See my experiences here.
Well, I finally rooted my SGP511 (bought in Germany, no branding, KitKat 4.4.4, no official OTA Lollipop update available so far) and everything went fine. For other noobs, I'll write my experiences.
As I could not make a nandroid backup before (no custom recovery yet) I finally did a backup only by Helium and Google app sync. I knew this is not comparable to a nandroid, but I finally did not have too much work to reinstall missing apps etc. Most of the work was to remanage my homescreeens and setup of e-Mail accounts.
Then I did the following steps (you can find all of them by using search function):
- All windows drivers on my PC worked properly before, so I did not change anything.
- I took off my external SD-Card, as I did not know if it will be formatted. Charged tablet battery to >90%.
- Downgraded from firmware 23.0.1.A.4.30 (KitKat 4.4.4) to 17.1.A.0.402 (KitKat 4.4.2) by flashing sgp511_17.1.A.0.402_generic DE.ftf with flashtool V0.9.18.5. No problems at all, tablet booted exactly like on first start after unboxing.
- Rooted the tablet using Easy Root Tool V12.4. This seemed to hang up after message "cleaning up", but when I hit Ctrl-C and answered the question "Cancel batch job ?" with "N", I got the message that the tablet was rooted.
- Installed SuperSU by chainfire via Play Store, no problems.
- Installed ES File Explorer via Play Store (to test root), activated Root-Explorer. Got a SuperSU message ("Allow root access?"), so root was ok.
- Backed up my TA Partition with Backup TA V9.11. I do not intend to unlock my bootloader, but this was recommended, and it just takes a minute. After backup, I tried a "restore dry-on" and got the message that the backup is working.
- Installed XZDualRecovery 2.8.15 (TabZ2-lockeddualrecovery2.8.15-RELEASE.installer.zip from http://nut.xperia-files.com/), no problems. Booted automatically to TWRP 2.8.6.0 after installation. After rebooting the system one time to finish installation I went back to TWRP and made a full backup of my rooted firmware 17.1.A.0.402 (just for security reasons).
- Installed newest prerooted firmware 23.1.A.1.28 from this thread using TWRP. This upgraded my tablet to Lollipop 5.0.2. I was not sure if this firmware would be ok for my german tablet (as it is Customized NCB) , but kulvertti (Thanks for your work!) wrote that region doesn't matter for WiFi-only tablets. I can confirm this, I can't see a difference to generic DE firmware.
- Tablet booted normally to Lollipop, installed most of my apps via Google sync etc.
I was really surprised how easy all this was. I now have a rooted tablet, upgraded to Lollipop and a custom recovery which allows me easily to make nandroid backups or use Titanium Backup. It's just great!
P.S. After installation of XZDualRecovery, and while I was still on firmware 0.402, my tablet announced an OTA update (back to 4.30). As far as I know, this can only be installed with stock recovery. I don't know what would happen, so better do not accept this.

Thanks a lot for this detailed post, it helped me a lot to root my Lollipop tablet
I was a complete noob on Z2 flashing and so on (coming from Nexus 4, it's really different) but this step by step guide is really helpfull.
I had a problem on the first step because I was using official Sony flashtool and you need to use this one: http://www.flashtool.net/index.php
Another thing for noobs like me: to boot to TWRP, you need to hit Volume key at boot when led is green, for more info look here :http://forum.xda-developers.com/showthread.php?t=2785598
Hi there,
my rooted tablet works fine with kulverttis prerooted stock rom, but now I would like to make a next step and try a CM custom rom. Here are some questions about that:
- Do I need to unlock my bootloader via Sony developer site as described on CM website? Or is this not necessary (as my tablet is rooted yet) and can I directly flash the zip file downloaded from CM?
- If I would like to go back to prerooted stock rom, will I only have to restore my TWRP nandroid backup or will there be other steps to do (like relocking bootloader or anything else)?

You need to unlock your bootloader to flash Custom Roms like Cm or Pac. Don't flash it on your device with looked bootloader this will softbrick your device.
If you want back to stock and you havn't a nandroid backup you need to do a factory reset and reinstall all apps
but if you have a nandroid backup you have to restore the backup only. You don't need to relock bootloader or and any other things
Well I tried to unlock my bootloader, but I don't get access to my tablet with fastboot commands. That's strange as I don't have any problem to get access with adb commands. My PC drivers seem to work properly.
But when I put the tablet in fastboot mode (LED is blue), I get "waiting for device" on every fastboot command. What 's my mistake?
Additional question: the unlocking will erase my internal memory incl. Dualrecovery, right? So after the unlock, I will have to flash TWRP first via fastboot, then boot to recovery and restore my nandroid?
Found it by myself when trying to unlock via Flashtool:
Flashtool showed "Root access denied" and on my tablet I shortly saw a message that superSU had denied rights to adb shell. I went to Apps - superSU and accorded rights to adb shell. After that unlocking procedure of Flashtool worked properly!
P.S. Dualrecovery was not erased by the unlocking procedure, so for the moment I could restore my nandroid backup of prerooted stock ROM. I'll try CM12.1 one of these days.
Installed CM and it runs great. On my internal SD, used space is 3.0 GB now compared to 6.8 GB on stock ROM! That's what I call a lean system.
