[Q] About Unlocking, Flashing and Rooting - General Questions and Answers

Hi, I am new to XDA and this is my first ever post, so Devs, be easy on me.
I own a Sony Xperia SP device (c5302) which is currently running Android 4.3 (12.1.A.1.201) and I want to gain root access on my device.
I looked at several tutorials and videos and found that I need to have the Bootloader unlocked first of all. I am not sure about the exact procedure as every tutorial follows a slightly differently process.
Here are my questions as a newbie.
I want to know that what losses can I have if I try to unlock my bootloader?
After rooting, will I be able to get the same android and build version running on my device i.e. Android 4.3 and build 12.1.A.1.201?
Will I be able to get future updates from Sony that are shown in the phone as notifications as and when the updates arrive?
Is it possible to bring my phone back to the same condition it is in today? Like it was never rooted or the bootloader was never unlocked, because I want to avail warranty as well?

1. Warranty
2. Ofcourse
3. I think this is device / manufacturer specific...
4. You can always reflash to stock ROM, talking about bootloader some bootloaders can be unlocked but can't be relocked this is again device / manufacturer specific.

[Q] New to the Android world, i have afew questions for your

I'm totally new to the Android world and i spent many hours to read this forum to learn as much as possible about my device and what i can do with it. But now, i need your help on a few things.
KitKat vs Lollipop, does it make sense to upgrade to Lollipop now or should i wait? Is there any major know bugs?
Since that i only have a 8gb device, i would like to clean the apps as much as possible. There's many apps that i don't need but they can't be uninstalled. For example, all the Motorola apps (is there something that we really need from them?), a few google apps like Google+, Google Play Films, Hangouts, etc that i will never use.
I want a stable ROM that i don't need to patch every day to solves problems. When i read about CM12 for Moto G, i see people that have problems here and there and wait for the next daily build to give it a try. I don't want to play that game!
If i install a custom rom, i guest that future updates will not come from Motorola. How the updates work afterward?
It's ok if i must have my device rooted
I have read about stock lollipop optimized version by lost101 but it don't think that the versions currently available will work for me. I'm in Canada and the versions that i see is Brazil or Asia.
thank you for you help!
You have the xt1032? Is there any warranty left? If there is no warranty, I recommend unlocking the bootloader before doing anything. It is easier to restore a bricked phone if you have an unlocked bootloader.
If you intend to stay on stock, you need some of the Motorola apps in order to install OTA updates.
Well what I will say is. I'm in the uk using lost101s BR optimized and I'm very pleased with it.

The phone is new but i don't care about the warranty. I've read that i can unlock the bootloader with the Motorola tutorial. I must be honest, i'm a little bit lost. I don't fully understand the difference between "unlocking bootloader" and "phone rooted"!
and yes the model i have is XT1032

You must unlock boot loader first then flash a custom recovery (manually or there is a tool in the development section) then rooting next.
Unlocking the bootloader allows you to install non-Motorola software. With a locked bootloader, the only software that can be loaded on your phone would have to be digitally signed by Motorola.
Rooting gives you administrative access to the system files.
You may not need an unlocked bootloader to get root and you do not need root to unlock a bootloader.
Start here to get the bootloader unlock code: https://accounts.motorola.com/ssoau...ct/standalone/bootloader/unlock-your-device-b
I tried to install TWRP (any version available) but it take like 1 minutes to show the home screen and im not able to "swipe to unlock". So i have installed Philz recovery and then installed lost101 Retail Brazil 5.0.2 Stock ROM (Optimized) v1.1a. I'm playing with it right now and so far so good.

[q] need root assistance

I have an Xperia Z3 D6603 running android lollipop 5.0.2 and it says in my service menu that im not allowed to unlock my bootloader. ive heard that its posssible to change this on multiple occasions and seen phones of the exact same model and firmware as mine that have unlocked their bootloaders and rooted their phones and i would like to do the same. i have tried different methods of unlocking from both official and unoffical sources, with no success. if anyone can please tell me how i might change the status or how i can unlock my bootloader and root (yes ive heard the risks a million times, no i dont really care about losing the drm keys that allow better lowlight conditions with the camera, and my phone actually has slowed slightly since the lollipop update) it would be much appreciated and of course if any additional info is needed, i will of course provide such as quickly as i am able to. thanks in advance and all input is appreciated.
you cant unlock the bootloader then, if you want root then you will need to downgrade to kk and root the device and install a pre-rooted lp rom

Xperia z3 d6633 23.5.a.1.291 (dual sim)(help)

So basically I want to root my phone.
As mentioned in the title above, this phone of mine exists nowhere as per MY knowledge in being root-able.
This phone was able to be rooted in lower versions. Now I don't think it exists.
1) THE OFFICIAL SONY SITE, won't let me unlock the bootloader.
2) Without unlocking the bootloader I THINK I won't be able to flash a custom ROM.
3) I need help with this.
-Unlocking the bootloader.
-Rooting it
-Getting the best custom rom
-MAYBE being able to use Nougat.
So can anyone on this website kindly help me?
I am a noob and am pretty new, so my knowledge is low, but I am looking forward to root this device now.
Regards

What does it mean to have an Upgraded Unlocked Bootloader?

I've started learning about custom firmware and Xperia Z3 customization a day ago, since I couldn't stand the stock firmware. My current goal is to flash Lineage OS 14.1 on my D6603. And in the post it says it require an Upgraded Unlocked Bootloader. Now I do understand the Unlocked Bootloader part, but I'm not sure about the Upgraded part. And I've done some read around the forum and found one that refers to it but I'm not sure. Doing Google search didn't show too much information about it? The reason that I'm not doing more research is I'm kinda tight on time these day. So much appreciate to anyone can help.
Also my D6603 is currently running the latest MM build with Root access and Dual recovery installed.
The updated part refers to the latest official bootloader from the Sony Firmware .291.
It requires Sony Software called "EMMA" (instructions are easy to find).
Connect your device and flash the latest firmware to get the bootloader on your device.
Backup all your data in case something gows wrong (especially the one on internal storage as it gets wiped in the process I think).

Really appreciate your reply. Would that allow my phone's bootloader to be unlocked too? Because I've just read around a bit and according to the Sony's UnlockBootloader site, I can't unlock it. And I just don't want to be stuck with MM build.

if it says "unlockable - no " in your secret menu I guess it isn't ... but I never had to investigate this.

Custom Rom

My friend changed my custom rom to CyanogenMod and now I am deciding to change the custom rom again. Can someone help me about changing it. I only have few knowlegde about it. Do I need to unlock the bootloader again or not? From my recent research some they that if your device was rooted there's no need to unlocking bootloader.
P.s Can anyone suggest a new custom rom for my device Samsung Galaxy Avant 4.4.2. As of now it was on CyanogenMod11 custom Rom?
Rooting Android OS means to add a functionality called su to it, whereas unlocking device's bootloader means to give you complete autonomy over your Android device. It will trigger a factory reset that will erase all of your data. It will also allow you to install a custom ROM on your device. Unfortunately, it can also compromise the security of your phone and/or can brick your phone making it impossible to turn on.
To unlock a device's bootloader it's NOT needed that Android OS got rooted before.
so it means that I can change the custom rom without unlocking bootloader because my device is ROOTED?
Exactly the opposite is the case: carefully read posts.
