Firstly, this is not my first rooted device.
For all intents and purposes, I do not trust the rooting methods posted here in XDA.
Is there a safer or official way to root my Z ultra?
I do not intend some jackass getting any personal info from my device or harvest my IMEI.
I have tried the flashtool http://xperiafirmware.com/8-firmware/41-sony-xperia-z-ultra-c6833
I ran it and let me be honest, its not something I would reinstall ever again. I did not go further with the procedure and removed it.
To make it clear, I do not want a third party tool that does the "Rooting" for me. I can program if I have to.
Of course, I would not mind a tool if it was open source and I could compile it myself.

It's a pinned sticky, I doubt mods would allow any illegal/infected software to be posted let alone pinned.

They install the needed/required binaries and apk to root your device. They both do not work properly on the very latest ROM versions so you will need to be on the previous iteration at least.

My 'tool' does not root, it only installs recovery. If you want to root it you can flash the su binary and supersu apk from recovery... but thank you for your confidence, the quality and trust worthiness of my packages is something I take pride in. :good:

This question is related to the bootloader problem & the upcoming 2.1 update....Could SE change the way the bootloader works and negate the progress you've made?
Sony Ericsson Xperia X10
since its not yet cracked ...i dont think SE will change the bootloader ...
i am not a dev .. this is what i think... but may be the new 2.1 needs a new bootlaoder ... so anything can happen .. but dev are keeping an eye on SE will loads its stock rom.. that way we can find ways to use to crack bootloader
I hope i can borrow this thread ...

No, the default apps which came with the phone are located in a place which you can only reach when you have root access

One click root method, you literally have to install the .apk then click root. After you remove the programs you don't want, then click unroot. Doesn't get much easier than that
IS this one click method universal or specific from phone to phone? i am asking for my X8. There isn't a thread about this phone yet and because it is part of the same model group i'm asking here.
what?
What is horrible, the devs are days without saying anything about the breaking of the bootloader, we will do with the 10 x?, I begin to think that it is time to change by a HTC
you are the best, I encourage all devs, is that you can with this, I encourage and give them strong these of SE, thanks!
i go into the dev section and i go into http://forum.xda-developers.com/showthread.php?t=1509855 and there are so many links to different threads and its like go here for this and go here for that can someone make a thread for noobs like me with everything in the same thread with a step by step guide

Alright so you said you wanna root but the link you provided was for a ROM. So which one are you looking for?
Root basically unlocks your phone to allow you to access your system files and make changes. So you can delete those annoying apps that come with your phone or allows you to use some apps that require root like titanium backup.
A ROM is basically a whole new software for your phone. like having windows xp and changing it to windows 7 or a better version of xp.
Here is a link for a Root for your phone. Super easy to use. Just follow the guide.

Root first....then eventually some nice developers will start posting their ROMS...either custom created and/or ported from other phones. They typically will put together step-by-step instructions in their posts, if nothing else, to avoid 8 million questions on how to load their ROM. If not, then i wouldn't bother with that particular ROM.
For example, Cyangenmod is a popular ROM that MIGHT be ported to the AT&T Note. If so, it will have very clear installation instructions http://www.cyanogenmod.com/ . MIUI.us is another popular ROM that might someday be ported over to the AT&T Note.
You might want to cruise over to the International Note Development forum and look at some of their ROM threads to get a feel for "how to" install a ROM. It will take a few times and you'll be able to load ROMS w/your eyes closed. Remember though the international roms will not work on our at&t note.
how to root AT&T Note.
http://forum.xda-developers.com/showthread.php?t=1504218
anyway, just my thoughts.
Just to clarify Philly- those roms for the international note are not compatible with our att note. Do not flash them. Just learn the procedure and wait for att roms to start being posted here in this forum.
thanks for the feedback and help i have rooted my note and enabled free tethering now i will wait for some kool roms to try out hopefully ics lol but i didnt see a quide for installing custom roms is there one ?
another pointer to a root guide
Andrawer is correct and I believe that root option works. As a lot of people have said it is very important to read then read some more. I had concerns about root method Andrawer also found, so I kept searching. I found a great step by step summary by Capite post #87 of the [SYSTEM] ATT Galaxy Note Root, and it worked perfect for me.
http://forum.xda-developers.com/showpost.php?p=22920576&postcount=87
The big issue addressed by this method was avoiding the Flash Counter, so that there would be no warranty concerns. Simple easy instructions and I had my Note rooted in less than 3 hours of purchase.
Please, forgive if this post does not go here, sorry!!!
I have a Sony Live Walkman that I bought without any phone company in between. (Sorry my English doesn't help, don't know the exact term for that).
I checked, and it says that it is allowed to unlock bootloader.
But my question is, what is the benefit in my case? I don't have any garbage from any company loaded on my phone, the loader image is from Sony.
I can't grasp really well why is there the need to unlock bootloader. I'm new to Sony, I just had a LG - and the only concern was to ROOT and nothing else.
My Sony is rooted already. Do I need to unlock bootloader? (I'm just repeating myself a lot, lol) - and let's supossed I do unlock it: what happens? what new things I can/cannot do/break/etc?
Thanks a lot in advance for any info you could provide me, I learnt a lot in these last months, and with this Sony things are.... different....

Unlocking bootloader lets you install custom kernels and ROMs. If you do it via official way, you lose your guarantee and your DRM keys, that means you will not be able to use TrackID and some other little features. If you patch it via unofficial way (test point method) you lose nothing. Anyway, if you don't intend to change your ROM, don't unlock it
Sorry that I'm a bit slow , but what is the "unofficial way" to do it?
I don't plan to install any custom ROM, but would like to try some new Kernel - and I believe I have to unlock bootloader for that?
I managed to root without unlock it, I wish I could flash a new kernel the same way
Unfortunately, you can't flash custom kernels without unlocking the bootloader. Check THIS thread, you'll find useful information
Well the unofficial way will allow you to keep your drm information and you will be able to keep using the track id app. here is a video of the method you need to follow to unlock it the unofficial way http://www.youtube.com/watch?v=FgYAZoqsk9E, the video it's from fast gsm but it is the basic procedure of the test point method the only difference it's the software you will use and of course that it is free.
Thanks guys, very useful info. Just one last thing, cause one of your responses confused me:
The official method will let me flash Kernel
the UN official method won't
is that right?
Thanks again, promise I'll read all those articles now.
any method will let you flash a custom kernel the only difference is that using the official method you will lose your drm (digital rights management) for protected music, the usage of the track id app and any way of officially update your phone (over the air, ppc or sus) and using the unofficial way (test point method) you will keep the drm, track id and you will be able to update your phone using ppc or sus.

Well, I been finally reading about this unlocking booloader stuff.
The so called " via unofficial way (test point method)" looks very complicated, like I could really break something. I mean, wires? Needles?
I think I will go for the official way., even if i don't like the idea.
Did official method also.
It is much more simple, just on the computer.
You will loose the track id feature, never used it anyway.

Hello,
I'm really confused should I root my phone or not, I want to have apps like titanium backup, juice defender, screen cast etc. But on the other side I don't want to lose my warranty. So I created some questions that you can answer me to help me decide.
Why should I root?
Is it worth it for some apps?
Is rooting safer than installing a custom rom?
Is it hard to do?
Should I install a custom rom ?
Is there any way getting back your warranty?
Should I root it because I have the phone only a week?
Any good guides?
What to do if I brick my phone?
Will I still have all apps?
What are the pro's and con's?
Any more information I need please post.
Hit the Thanks button!
I think you can simplify the questions by asking yourself whether you think you are someone who likes to tinker with their phone and get under the hood a little, or whether you are generally happy with how it's working now and merely curious what all the fuss is about?
You may conclude from either question that rooting is worth a try. It's probably a good idea to have at least a good reason to (such as wanting to install a root-only app like AdAway or having a custom recovery like TeamWin or ClockWork Mod for backups and such, or for installing one of the cool ROMs we have available in these forums).
I was apprehensive the first time I rooted, but now I can't imagine running my phone without it. Especially thanks to the custom ROMs we have here and the many mods and apps that require root/busybox/init.d etc to run. That said, I wouldn't advise rooting to someone else unless they were comfortable with the notion that they might not be covered under warranty anymore, and would have to rely on their own and this community to deal with any problems they might encounter. You can get your phone back to stock ROM and unrooted, with a locked bootloader but I believe it will still indicate at the bootloader that you 'relocked' it, so your provider can tell that it was tampered with and may decide that that's a good enough reason not to honor your warranty. Proceed at your own risk.
As far as the details, no it's not very difficult to root your phone. You need to be marginally competent at running some software on your PC and follow the tutorials available here. There's this tool which makes things very easy, and there's also nloooo's tutorial here if you want to do it more manually which is helpful in learning some of the basics of using adb commands and getting your PC to talk to your phone, etc.
If you follow the instructions in the tutorials you shouldn't brick your phone. You just need to be mindful of what you are doing and don't do silly things like pull the USB cable while it's sending files to your phone. Even then, there's usually ways to recover from those situations. It's hard to actually brick the phone.
Backup your phone, often!
Hope that goes someways towards answering your questions. Good luck!
Reason to root for me:
Adaway - to remove ads temporarily
Sixaxis - to play games with ps3 controller
BetterBatteryStats - to check what prevents deep sleep such as alarms etc
Titanium backup - to backup my stuff just incase something happening to my phone
That's it. If you don't need this I don't think you need to root at all.

Why should I root? Ans: Please google. You will get ample number of example why you have to root your phone.
Is it worth it for some apps? Ans: Yes. Most of the apps which benefits need root access.
Is rooting safer than installing a custom rom? Ans: You can not install custom rom without having Root access.
Is it hard to do? Ans: Depends on your knowledge. If you follow the processes mentioned in this forum, should not be an issue.
Should I install a custom rom ? Ans: Again your choice. I will prefer to go for Custom ROMs.
Is there any way getting back your warranty? Ans: No, I do not think so.
Should I root it because I have the phone only a week? Ans: That does not matter. I rooted my phone once I came back with my phone from showroom.
Any good guides? Ans: It is available in the forum. Please search.
What to do if I brick my phone? Ans: First you should not face any issues following the guide here. If still bricked then your bad. I have not bricked till days, where I am having very less knowledge in android. Take always backup before doing something unknown.
Will I still have all apps? Ans: Rooting does not delete any apps. You will get the power to delete bloatware and install so many apps those need root.
What are the pro's and con's? Ans: Please refer answer 1.
Any more information I need please post. Ans: Please check this forum. Everything is there..
Hit the Thanks button! Ans: Sorry I can not becoz I am helping you so I should get thanks from you. :laugh:
Best of luck..Gain some knowledge before going ahead with root that will give you more confidence.

Depends on how you bricked it. And if you can flash a recovery.img or RUU, it's not a real brick.
But about the rooting:
I've rooted every device I owned + lots of other devices. It's surely worth it. ROMs make the device so much smoother, and when using atis112's kernel, you'll get the most out of your device. It also removes bloatware, and allows full theming. I don't see any problem with it, except the OTA's. But that's not that hard, you can flash the stock recovery/RUU, and you'll get them back.
In my experience, there's a really small chance of bricking your phone.It's a safe method.

I own Desire X.
May be i am very late in replying but i ll try to answer some of ur questions.
I am new to rooting scene so in case of any wrong information, please correct me.
I will share my experience.
I rooted the phone coz i wanted access to limit my startup items. In addition, rooted phone can give u access to ur device completely.
Tutorial made by nloooo is awesome, otherwise its better you follow the tutorial specifically made by the developer of the product.
TWRP recovery is cool and serves the purpose.
I tried Elegencia ROM and now i am using mySENSE-dx_RC3.0. I really hate all the bloatware in my phone which is te main reason for installing ROM.
Going back to custom ROM is easy (i think), for that u need to have a full backup of ur system in TWRP.
Going to ctock ROM is a bit difficult using RUU as stock ROM in RUU need compatible CID of your phone.
Both these ROMs i mentioned above are are awesome and u can choose any one depending on ur needs. Advantages of Elegencia are that you can choose which software to install through aroma installer while installing ROM. Its light, flawless and cool.
Why i chose mySENSE-dx_RC3.0 is that i really loved Full Sense as compared ti sense lite in stock as well as Elegencia ROM.
Hi all,
I've studied all 8 pages of current Q&A forum and did not found a guide or instructions on how to dump stock ROM from not-yet rooted pre-.402 BL-locked device into FTF or other flashable format (complete out of the box stock).
Everything which I've read points to PC Companion and download route, however Support Zone downloads latest version .402 in both Update and Repair scenarios. I've even tried to fool the tool with "no update "XML responses (I can provide details), but it did not work: 402 only.
I can see people posting .36 FTFs for regions other than mine, so I'm interested in the process how to make such FTF myself.
On a side note I'm well aware of SIN files, FTF files, Flashtool and adb-based rooting tools like EasyRoot and Community_RootToolkit.
At this point I'm not planning to unlock bootloader and loose TA, least intrusive safest backup of ROM is what I want.
I'm not a complete noob and did a week of web digging for possible approaches, so please no bashing
Thanks in advance.

OK, I was ready for some hostility here. I'm not sure what's your problem man, but if you have nothing useful or constructive to say, please say nothing. I've seen you posts on other threads with the same attitude but with zero useful info.
If you'd read my post with attention then you'd see that common approach with Update Service which is now a Support Zone gives LATEST .402 firmware only. I already have it sitting on my disk. I'm interested in dumping my own tablet's current firmware which is version .36.
PS: A "week" is a week only with Z2. That's my 4th Android device among 2 HTCs and 1 Samsung, so please cut the BS about not doing a decent research.
Why do you want to dump the .36 firmware?
I don't see any use for that. There is nothing you could wish to do with the tablet that requires .36 instead of .402.
If you want to be able to restore to factory state (e.g. for warranty purposes), then .402 is perfectly fine. There simply is no need for the .36 anymore.
I usually make a snapshots of the devices to have a possibility to restore them to the exact state they came from the shop.
Regarding this specific case, I want to preserve root exploits in .36 which were fixed in .402. Also, I'm quite happy with .36 firmware since there's no issues for me, so I do not see much sense in upgrading to .402.
BTW, are there any obvious reasons to go .402?
You know you can root 402 right? No unlock required

Yes, I know, TowelRoot should work on .402. As I've stated earlier I'm quite happy with .36 so it is a good idea to have both possibilities to flash: .36 and .402 in case I would not be happy with .402.

Personally I think that what you are trying to do is a very smart move as I have an experia m2 that came with 4.3 and everything worked great with it. I then made the mistake of falling for the "you have an update", updated to 4.4 and hate it. Its caused nothing but problems with most of my software that I have come to love. When I use pc companion to flash it just installs the latest software (4.4). If only I had made a ftf of my factory rom
Good luck!!!
