Hello XDA forums, i've recently bought a Sony Xperia Z1 (C6906) and it has android KitKat 4.4.2, i'm not sure about the exact version tough, update center says that it's the most recent version. Now I have a couple questions,
1) First of all, I want to root my device and my former experiances on Android was on my Galaxy S4, which i could simply use Odin to do most stuff. From what I understood, that option is not possible, at least when my phone is just, stock. How can I root this stock phone easily?
2) And also I've heard that I had to downgrade the device in order to be able to root it. I don't want to downgrade, especially to 4.3, can't I just root in the current firmware?
3) Is bootloader a dangerous thing to mess with? Some say if I don't take backup of TA, I may hard-brick the device. Is that true? And is it an easy thing to do? To backup TA, do I have to root?
4) Also how can I install CWM to my device. I also want to install CWM on my device.
Thanks..

Yes, messing with the bootloader can lead to a hard brick, yes you need root to backup the TA

To root your Z1 (C6906) you have to downgrade to .534 Firmware, Install DualRecovery, Ungrade to Pre-Rooted Kitkat by NUT.

Is not dangerous. You brick phones just doing mistakes. You don't have to Unlock Bootloader to gain Root. So skip this part.

Download the lates DualRecovery for Z1 which have CWM, Philz and TWRP Recovery, all 3 in one. Just run the application from PC and install to phone, but you have to be on .534 FW.

This is why the people get confused. Downgrade to .534 first, then install DualRecovery, then follow the Instruction from that link to get to your Firmware Rooted.
I think @[NUT] should add this steps on his threads for people like you who start from not rooted .681, .757 and so on.

Well, I tought Sony would be just like Samsung, after all they are both androids is what I tought. Well, it's diffrent :/ Anyways I got to make sure about the things I do, because they may end up as bad things such as brick or etc.
I got it now, it's almost done.
Back in S4, all I had to do was to take the phone into Odin mode, then flash tar.md5's via odin, and it was all over, I installed cwm and rooted without downgrading and so. I feel sad that Xperia wasn't like. Well it's a great phone tough..
thanks alot everybody!

Just put the .534 FW in Flashtool Folder and flash it. Then connect to PC and use the Installer to install Dual recovery...the rest you know...
BTW, wipe everything any time you flash anything (Data, Appslog, Cache) to execute a clean installation. Yes, you will lose your data, but better be safe instead have issues later.

So, having root and recovery without unlocking bootloader in version .757 OFW is not possible? The thing is, I don't really want to unlock the bootloader, but i really want to have root privilleges, recovery mod is optional tough, i tought i could root easily with using CWM. So what I want is not possible?

No, I understood but kinda didn't wanted to.. :/
I already downgraded, rooted and installed recovery. Then I updated to stock rom 757 back, thinking that I could simply root using recovery. Anyways, after I updated, I couldn't get in to recovery mode, because the one I installed was without unlocking bootloader, I simply installed firmware based recovery. I don't really think about unlocking bootloader, the TA codes and stuff kinda scares me.. I did took backup of my TA tough. I just need to have root in OFW Kitkat. I can do without recovery (which i can't install because of bootloader). But root is essential. :/

probably, you must be 100% stock rom and stock recovery to get OTA's, if you have relocked your bootloader then you will have to unlock your bootloader again so you can flash the stock recovery.
stock recovery is here, as long as your OTA is 7.19.401.2: http://forum.xda-developers.com/showpost.php?p=59082816&postcount=2

Hi guys !
I unlocked my bootloader and rooted my device, and i don't know if i can upgrade my Nexus 6 by ota (received this morning on the phone) without brick it.
Is it dangerous?
Thank you
EDIT : I'm on stock Lollipop 5.0.1
Unlocked is fine. If you have root or any other system mods, you'll need to remove them.
Oh thanks for the quick answer
So if I unroot it with Nexus Root Toolkit it will be ok?

Nexus toolkit doesn't unroot. It reflashes the entire phone which also means root disappears. If you're going to do that, no point taking the ota. Just flash full update.
You can indoor via the SuperSU app.
Oh ok I just saw that.
So if I unroot via SuperSU it's ok i can install?

download the factory image that you want to update to.
extract the system.img, boot.img and radio.img
Fastboot flash them.
You could also flash the bootloader if you want though I dont see any point.

Hey , im new to rooting and the forums so sorry if somethings are not properly explained.
I recently managed to root my uk variant m7 unlocked to any service with the latest twrp recovery.
I have recently found the venom rom which i would like to install to futher customize my rooted device, but i need to upgrade my android to 5.0.2 and i am currently on 4.2.2.
in the toolbar it says 'system update avaliable' and after installing it says 'system update ready' and im guessing this will bring me to 5.0.2 firmware. after clicking on it it reboots my phone and for some reason enters the recovery. from this point i do not know what to do.
so to summarise, i need to upgrade my m7 from 4.2.2 to 5.0.2 nut when i do it enters my twrp recovery and i do not know what to do
system details:
HTC One M7 UK variant unlocked to any service
rooted with SuperSU
Stock rom (4.2.2)
Stock kernel
Thanks

You can't update your phone in its current status. You need stock recovery installed, unmodified /system files and /data/preload which is deleted during the htcdev bootloader unlock process. You'll probably need to use a RUU or something else.

A factory reset only wipes user data. Root files are stored in /system partition which is not affected by a factory reset so short answer no, like I said you'll probably need a RUU or something else (stock odex rom/nandroid backup/guru reset rom) to reset your phone back to stock. Post the output of "fastboot getvar all"

Its possible to download the update elsewhere and install it through twrp recovery?

If your phone is S-off, you can download the Ota zip files and install them incrementally (can't skip a version) using stock recovery. That doesn't change the fact that all files in /system and /data/preload must be unmodified.
Imo, the simplest way to update if your phone isn't stock is with a RUU. If your phone is stock, reflash stock recovery and update with Ota, if it's stock and soff you can update with Ota zip files if you can find all the ones you need.

Nexus phones are actually very easy compared to Samsung. Rooting has nothing to do with flashing custom ROMs, you just need to unlock the bootloader. If the custom ROM is not pre-rooted you will have to do so after flashing and the instructions will vary based on the custom ROM you flashed.
Why in the newbie guide u need to root first. No, samsung is much easier and very hard to brick ur phone if u did flash it in a wrong way unlike in nexus.

Some custom ROM's come pre-rooted, meaning you don't have to do anything after installing the ROM to root the phone. Other custom ROM's are not pre-rooted so you have to root the ROM after installing it. As an example, the stock ROM is not pre-rooted so you need to follow the instructions in one of the many threads that explain how to root the stock ROM. It is nearly impossible to brick a Nexus phone as long as you have a custom recovery installed and the bootloader is unlocked.

The bootloader is already installed on your phone, it is part of the ROM. As far as unlocking the bootloader, here is one of may results returned when Googling "Unlock Nexus 6 Bootloader" You need to do some research on how to unlock, flash and root the Nexus 6, the information is there if you just search for it.

There's only two ways to brick your Nexus 6.
1. Disconnect cable while flashing bootloader.
2. Close bootloader after flashing all stock without checking if it boots.*
Other than that you can always boot into bootloader and do stuff.
* +1 That's recently happened to people: Everything is off, including Enable OEM Unlocking, and you receive a borked OTA. That happened to some people unfortunately.
