Hello everyone, I have questions. I will be happy if someone could help me understand Android better.
Edit: find most answers here https://android.stackexchange.com/questions/21460/what-does-fastboot-oem-lock-do, the following remains:
Is locked OEM equal to locked bootloader?
If not, which is more serious e.g. undesirable when using rooted custom ROMs?
Is it possible that booting fresh custom ROM will lock bootloader (or OEM..) back without asking? just like this happened to me with stock firmware
Is it dangerous if bootloader gets locked and I use TWRP?

I am just jumping into the android moding world, and I just can't seem to find clarification on a particular issue. It seems that most phones are rootable but many have a locked bootloader. From what I can glean through reading many posts here and searching the web, the geekish options that you give up on a phone with a locked bootloader is the ability to flash the ROM. However, this is contradicted by examples here on this site of ROMs for phones with locked bootloaders. (Moto Atrix for example.) Is it that custom ROMs can only go so far with rooting alone, like the inability to replace the kernel? What exactly do you give up by only achieving root with a locked bootloader vs a rooted phone with an unlocked bootloader? Is it ROM related at all?

You can't flash a custom rom without root. Root is needed to write to system partition etc.
But you can get root without a custom rom.
A locked bootloader means you will have to stay on stock rom. Means no custom kernels, no custom firmware.
Someone correct me if im wrong.
still confused
As mentioned there seem to be custom ROMs for for phones with a locked bootloader. The new Motorola Atrix is an example. While there is complaining that the bootloader is locked there are custom ROMs (2, I believe, so far) available from members of this forum. What is it that can't be done with a locked bootloader?
I'm still confused, but I appreciate the reply.
Hey guys, im new to this forums so first of all, hello everybody.
so, i have this xperia l, and im not new to android devices, and i want to flash a kernel and a rom (more specificly, thunderzcap and ios7)
the problem is, i cant unlock my bootloader. In that screen after you type that weird combination of numbers in the dialer it says that i just cant do it (not allowed). I read it somewhere that i need my simlock code and something else, but according to what i know (and i dont want to believe t) this means it is permantly locked.
So anyone here knows how to solve it? I would defenitly love to unlock the bootloader so i can flash a kernel... or im stuck with my phone? i know there are other roms but it isnt the same thing...
Thanks in advance
If it's locked there is no going around it. So answer is no, if it says on the phone that bootloader is locked you can't unlock it. And there are NO roms that work with locked bootloader. For you to be able to flash a ROM on it you must have unlockable bootloader.
Sorry to give you bad news but that is way things are in your case.
Nothing you can do.................for now.
If we can get CWM going on the phone, we can flash packages. From there, if this can be extended to our phone, http://forum.xda-developers.com/showthread.php?t=2595238 then we can run CM variants on top of stock, and thus there is hope for the locked bootloader people, like myself, hopefully.
Hello, I am at 5.0.2 completely stock and Moto G XT1032. I want to unlock bootloader, install recovery, and custom roms because 5.0.2 is slow and laggy.
I heard about some problems if I start at 5.0.2 and doing those things, such as ripple effect, flickering ....
So what I want to ask/confirm:
1. Is doing those thing possible?
2. What are known problems if I do those things at 5.0.2?
3. Problem like ripple, flickering, unlock bootloader warning... only happen in recovery/booting or even when the phone runs?
4. Any risky things such as bootloop and cannot be fixed .....
Thank you very much.
Same Question from me
Hi,
Same Question from me too.
Please someone who has done this, please reply.
I had rooted/flashed many mobiles, but its being increasingly confusing for xt1033 with every new versions of rom / bootloaders and increasing numbers of Bootloop and HARD Bricks described in this forum.....
Please experts, please reply.
Before proceeding, check the Motorola website to make sure the bootloader can be unlocked.
Unlocking the bootloader will also wipe all data and apps from the phone; that is, it will perform a factory reset.
In my experience, phone operations are not be affected by unlocking the bootloader and installing a custom recovery except you cannot install stock OTA updates without stock recovery.
Hello. What's the easiest way to backup everything (and I mean everything, including detailed app data) before unlocking my bootloader? I want to flash a custom kernel with minimum modifications to anything else, and obviously I want to take a backup of everything before I lose them with the unlock process, but I haven't been able to find a way to do so on a stock ROM that's not even rooted.
Or is there a way to root my phone before I unlock it?
I've never had a OnePlus device before, so here I am, asking dumb questions. :silly:
Also, one more question (in three parts, sorry!): since some of the newer apps, especially banking apps, have started using stricter safety procedures, they can detect an unlocked (or even merely rooted) device, and so they don't work. 1) Is there any way I can use a custom kernel on a locked (or relocked) bootloader? 2) Is it possible to use a custom kernel on an unlocked phone that's not rooted? 3) If neither of the two is possible, how can I prevent said apps from detecting my unlocked bootloader and rooted phone?
Thank you very much in advance for taking the time to answer all of my questions.
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.
