Chances are big that you will get a new phone so that would mean that you get a fresh installed OS anyways.
So I'd say just do a reinstall. That way you're certain that the chances of them finding out that you rooted the device become smaller.

[Q] Overclock without unlocking bootloader ?

Hello,
I followed this thread to root my phone. http://forum.xda-developers.com/showthread.php?t=2186368
Then i installed this custom recovery http://forum.xda-developers.com/showthread.php?t=2187363
Then i wanted to overclock using this kernel http://forum.xda-developers.com/showthread.php?t=2172888
But my phone need's unlocked bootloader in order to do this. (and i don't want to unlock it)
Any kernel that allow overclock with locked bootloader ?
Thanks
Im afraid not,AFAIK there is only one kernel that allows overclocking,and that is the DoomKernel by the awesome DoomLord

You will be waiting for a looong time. No one has managed to get the DRM keys back after relocking the bootloader.

You may actually want to have a good read of the terms and conditions of the Sony website for unlocking. It doesn't specifically mention that it breaks your warranty. It states that if your phone is send back for repair, it has to be on stock firmware. IF you are unable to do this they will charge you a service fee to have a technician repair the software (I'm guessing J-tagging or something more professional?). They do mention the fee for that was expensive. So basically if say for example you permanently lost radio (signal) because of a hardware issue that you in no way caused by flashing some ROM or tweak that messes with the drivers for that, it should be fine. It's a hardware thing - you didn't cause it. If you hardbrick your device and they have to bring it back from the dead, they'll charge you. If you overclock it like a mofo and burn out the CPU they will likely charge you for the initial software flash and charge you again for either repair/replacement of the logic board or complete phone.
That's the gist of it from memory. There may of course be some little clause or something that they could get out of it if they wanted that I skimmed too quickly, but you'd probably find if it's a genuine problem from them they would repair it. If you'd clearly messed with it and stuffed it, they wouldn't. Sounds like a normal warranty to me
EDIT: just had a quick gander at it again and here we go "Please note that you may void the warranty of your device and/or any warranty from your operator if you unlock the boot loader". I think the key word from that would be "may".
and also " In addition, if you brick the device, it is your own responsibility. " The same thing could be said with a locked bootloader and you stuffed something up trying to root it or hack it in some other way.
ROMAur allows to to change the cpu speed, how well this works is another thing. I have heard somewhere that there is some type of throttling within the standard kernel which still prevents the phone reaching the full potential, but custom kernel gets around this.
I have rechecked this and they have removed the overclock in the downloadable version

[Q] Rooting gives you CWM?

So the title isnt all to clear, however I am very new to Android. I am wondering if rooting gives you CWM; however I do not wish to have CWM because then I have to flash to get rid of it and if i am correct that means I void my warranty. So could I root with Bin4ry's root method and then manually do what I want to be done without ClockWorkMod?
Thanks in advance and any replys are appreciated
Oh yeah I have a Xperia T!

no, rooting does not give you recovery.
Flashing roms DOES NOT void your warranty, only unlocking the bootloader will do that.
If you are going to root I recommend that you install CMW, otherwise its very difficult to do things manually. You need to ask yourself "WHy do I want to root my device?" and realise that installing CMW DOES NOT void your warranty.

Thanks, I might root later I wanted to just add the Acid Music mod. I'm going to leave it for a while and maybe root after I have had my phone for a year or so.

You were going to try and add that without CMW? wow!! How were you going to do that!
Plus, you will read in that OP that the only way to get rid of that mod is to restore a backup, which requires CMW, and most people have had problems with that mod. Personally I don't believe it works at all and if it actually changes anything then it ruins phone performance. or those who say it does not ruin performance I believe they are only getting a placebo effect.
The only true way of getting a better sound performance is via kernel level tweaks not by flashing these kind of mods.
I suggest you root (If you follow the instructions it is 100% safe) and install recovery. It has NO disadvantages at all. And you can restore your phone back to factory settings via updating by official Sony software so that no warranty is lost and no one will know what you have done
I agree 100%
I tried Acid Mod twice now.
Not only is it a waste of time but its also a good way to get stuck in boot loop.
If you do try it, you are definitely going to need to backup first.

[Q]What to do with a fresh warranty repaired Dev Ed.?

Hello all! I'll be getting my HTC One Dev Edition back from warranty repair after sending it in for bootloop issues. My previous thread here http://forum.xda-developers.com/showthread.php?t=2457513 explains what happened. Stock HTC One (not flashed/rooted) went into irrecoverable bootloop.
So when I receive my phone back, what's the first thing I should do? Install recovery? I don't have any plans to flash/root my phone yet. Any ideas what to do to prevent future bootloops?
Cheers!

If you want to prevent bootloops and you don't have any plans to flash rom/root, just do nothing. Use it like it is :laugh:

Various noob questions

Hello !
I've a new Xperia E1 Dual (2105).
I've successfully rooted it, thanks to the information I've found on this forum.
Now I've some questions :
1) on my previous phone (Xperia X8) I had a recovery screen accessible upon reboot onto which I could make backups of the whole software on the SDCARD. I would like to have the same on the E1 but I can't find nothing to make this work. What should I do ?
2) Is there any advantage to run a custom ROM on this device, given it already has 4.4 ? (the X8 needed a custom ROM to go beyond 1.6 or 2.1 version Sony delivered).
Many thanks in advance for your help !
Recovery requires unlocked bootloader
Yes, you can backup stuff using PhilZ or TWRP. You can get into recovery by tapping the walkman button during Sony logo
We are currently stuck on 4.4.2, but there are many Stock ROM mods that speeds up it up the phone, such as KillaMade, Illumination, etc.. It frees your time enchancing the ROM, or If you are completely new to Android, It avoids you to give a few headache
If you are unsure what to do, check my guide, It is mostly noob-friendly

Thank you for your answer.
I'm a bit confused because I am not able to install TWRP because it says that my phone is unsupported.
I've cleaned bloatware using RUninstaller (backing up each APK before removing it) and moved the backuped APK to the SDCard and to my PC for a possible re-install. But I would have liked to make a backup of all the files with the device cold before tweaking ... I like having belt and suspender when going wild

Just saying using any TWRP app will always say E1 is incompatible, because it is not supported (officially) daily
However, you can install TWRP here: http://forum.xda-developers.com/xpe.../recovery-main-thread-twrp-xperia-e1-t3323159

I've read about unlocking the bootloader and saw that it will reset the phone/apps/settings to factory default.
I should have done it long before ....
But I wonder if there is a way to backup everything BEFORE unlocking and, restore after unlocking to get my settings back.
What do you think ?

Unfortunately I don't have a locked BL, so I can't really tell you how to make the recovery work, though there are many threads about how to boot into PhilZ under locked BL @xezrunner
If you do however manage to flash PhilZ, you can backup your entire system along with apps, data, and etc..
I suggest backing up TA, If you ever need to relock the BL back again to make use of the warranty
Here's the appropiate thread on how to install recovery on a locked bootloader.

Thank you very much but I've already used that and installed a recovery. You are late by a couple of hours.
I was able to do a backup of my present configuration and even make a "custom ROM" with the actual phone. So I'm very pleased !
I looked into the service menu and saw that my boot loader is not locked and that I've no DRM installed (maybe that's because my phone is a plain Sony one ? without any paid application ? )
Now, I've just to use the thread about changing the behavior of the Walkman button in order to disable it...
Thank to all who responded and provided help ! I'm an IT guy but far from an Android guy ! And I would not have done this without you !
Edit :
An additional question :
Now, I still have a locked bootloader (because I did not unlock it) and a recovery installed (PhilZ). Do you think I could install TRWP rescue still without unlocking the BL ? (this way I may keep the warranty of the phone ?)
TWRP is in a different image file (recovery.img), which locked BLs will never be able to boot in it
PhilZ is stored in the kernel (boot.img), so you can easily flash another ftf file to erase the kernel If you need to deliver the phone to your provider
(some providers take this seriously as this is a great excuse for them to ask for more money, or even worse, refuse to repair it, however Sony is still pretty calm about things like this)
As long as your BL is locked, and your TA is intact, your warranty is safe

The Xperia E1 has no DRMs whatsoever. What DRMs could you even have? The camera lacks any enchancements Sony has for the other devices...

Ah ! OK !
This clarifies a lot of things. I was wondering what's this DRM thing was about.
Last question, do you know if one can backup the official ROM downloaded through Sony PC Companion during "Repair phone" operation ?

There's a much better way to get a .ftf file that you can flash with Flashtool. Use XperiFirm.

It's amazing the volume and quality of information I got asking simple questions.
I would have had to read thousand of pages of this forum to get that much ! You definitely saved me weeks of investment.
Do you know if I can install a Sony software made for a different CDA phone ? Because I have an old X8 which came with Orange branding and it has been so badly configured it is a pity. So I would like to try it with plain Sony Ericsson software and compare with the ROM I tested on it.
Have a bright nice day !

Absolutely, you can flash any kind of firmware and it will work as long as it's for that specific model. You might experience some issues like no 3G if the firmware was made for a country that has no 3G support or has a different kind of cellular reception. But that's rare. The amount of bloat also varies beetween firmwares, of course. Kizoky has made a thread on all the firmwares available in XperiFirm with the fewest amount of bloat, I'm using the Turkey one and it's working really nice.
Glad to be of help!
Hello !
Here I am again !
I've a question I can't solve myself.
I've searched and didn't find an answer.
When I'm at work, I would like to send some calls directly to the answering machine without the phone even ringing. Mostly the personal calls because I can't get any privacy when at work.
Before the Android Era, I had a phone with a white list and a black list. And you could manage the actions for the white or the black lists. This served me well.
On my Android 4.4 I did not find something similar.
I would be delighted to get some help from you guys !
Thanks in advance for your answer.

Ugh, now that's some tough question.
Try asking in here: http://forum.xda-developers.com/android/help
Kizoky,
Thank you for your answer. Actually, i had an idea to search for just blacklist android. It was more productive this way. I've to learn how to search ...
I've found two ways : the first one (not working) is to activate the black list from the settings in the contacts. The second one is to download an app to do just that. For now, I've to find one acting just on the phone call and not on the SMS. Funny Sony or Google did not think it was a need to fulfil ...

C6603 Xperia Z 5.1.1 How to not brick my phone.

Hi there, I have a question. I read in the thread about unlocking bootloader that if I have updated my phone from "fota" my device will brick.
I have flashed a lot on my first 4 phones until I hard bricked a new s2 within 4h of owning it because of factory nand being corrupt and I didint read up on s2 bricks and how they can happen and haven't since for last 2 years done anything to my phones.
So my question is, I have a c6603 Sony Xperia Z and I assume I have the newest os version available, downloaded through OTA (ver. 5.1.1) will my device brick? is there an option like for nexus 4 I had that I could install a stock rom from Google. So get one from Sony and that would be an os not installed from OTA but done over factory update.zip or something.
Also can someone direct me and tell me again to refresh memory what do I need to do and how to get root and be able to back up stuff and get rid of the Sony bloatware and have a faster phone hopefully if roms still give that.
Thank you very much, sorry for bad English.

first of all , older galaxy like s2 s3 are incredibly easy to brick , just forget bout it if u really had no idea about it.
also , yes you can flash your xperia with custom rom without bricking it.
as long as your flash mode or fastboot mode work , there wont be hardbrick
dont forget to backup TA too
