But isn't there a difference between SIM unlocking and bootloader unlocking? Or are 2 and 3 here essentially the same? So confusing Just to add: but 2 is not always needed for 3 see root exploits. But most hardcore tweakers want 2 even if it is possible to get 3 without 2. If "locked" it may: 1 block attempts at flashing 2 refuse to boot the phone if something unauthorized was flashed.
Unlocking it means changing a setting that affects this behaviour. Rooting see what does rooting a phone mean Jailbreaking iphone word for rooting. In other contexts it may just mean replacing some files to customize your skin. While ROM may be a bit of a misnomer actually refers to non-volatile memory--not data , most people don't know the difference between a kernel, OS, bootloader and etc. See also Why can't they make a generic phone OS? Both are memory card standards that use NAND memory.
This means these memory formats come with a different or additional memory controller. The "e" stands for embedded and just means the storage is non-removable in the typical sense.
It is also slightly more expensive. Nandroid A system image used for backups. Often does not include the bootloader. In a more technincal sense the kernel can be called the operating system. It is a program that provides an environment for other programs to run safely and use its HAL. Mod e. Could be a complete operating system like CM. This is like a mini OS that allows users to perform maintenance actions such as deleting, backing up or installing files.
Custom Kernel e. LeshaK's kernel Part of the operating system that controls the hardware and all the other programs that run. It is the first non-bootloader code loaded. Firmware Software on embedded devices. Driver program used by the kernel to communicate with hardware. Typically written by the manufacturers of the hardware. The android source tree comes without kernel and drivers for most devices. THis is why non-google devices have a harder time keeping up-to-date.
Allows bootloaders to flash data to the NAND. SIM unlocking Certain mobile providers may offer devices as part of a contract. These devices have software restrictions on what SIM cards you can use--to prevent changing provider. So even moving a file to your sdcard can be called flashing.

Now, starting with the EVO 3D, we had this. We got around it using a method where we flashed kernels from fastboot instead of recovery. Team Win introduced a method called HTC Dumlock that allows flashing kernels sort of from recovery mode it sets up a script, boots into Android mode for a second, flashes via Android mode, and pops back out.
In the past, this has not been much of an issue. Having an unlocked bootloader does not mean you have root. You just have the ability to flash a ROM, which generally will contain a root-giving program. S-OFF means you have complete control of the phone. Security off. Do whatever you want from whatever mode you want. An S-OFF phone means you have access to write new radio firmware into the device.
HTC is required by their agreements with the carriers to do what they can to prevent users from being able to install firmware that could be potentially disruptive to the towers, or prevent the carrier from accessing your device without your knowledge, which may be required by the government or a warrant.
An S-OFF phone has no restrictions on what you write, so you could wipe the kernel, bootloader, and everything out and be stuck with a phone with no operating system and no way to do anything. An S-OFF phone can show that it still has a locked bootloader, although recovery will treat the phone as though it is unlocked.
You can also flash kernels and splash screens directly from recovery without any additional methods required. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I have heard these two terms the most, whenever people talk about Android OS.
One of them is Rooting or root access, and the other one is unlocking the Boot Loader. Are these two terms exactly the same? If not, kindly let me know the differences. S I am a beginner to android, and already searched a lot on the google, but could not come to a conclusion. A specific answer would be really helpful. Thanks in advance. Root access: Administrative access to the entire file system including the ability to change system files such as installing system-wide ad-blocker by modifying the host file on your device, or uninstalling system apps, such as bloatware that comes pre-installed on your device.
Unlocked bootloader: Even though it is possible in some cases to obtain root access without an unlocked bootloader, unlocking the bootloader is required to permanently root a device.
This is because your carrier can simply unroot your device with an OTA update. Typically devices sold by most carriers under a contract will have a locked bootloader, preventing you from installing other roms another version of android such as CyanogenMod or tampering with your device in any way. Obtaining bootloader access on these devices is generally obtained by using an exploit, so if you plan to root your device do not allow any more OTA updates from your carrier until you check the xda forums for what options you have for your device.
