Boot loader ir mazs programmatūras rīks, kas vairumam operētājsistēmu (arī uz datoriem) darbojas pirms pamata sistēmas palaišanas. Tas parasti ir specifisks katrai ierīcei. Boot loader, jeb sāknētāji ir arī Android telefoniem, bet bieži vien tie ir slēgti – ierīces lietotājs nevar tiem piekļūt un tādējādi ir samazinātas iespējas urķēties – mēģināt uzlabot savus telefonus. Pirms kāda laika HTC saņēma daudz pārmetumus, ka saviem telefoniem ir slēdzis piekļuvi sāknētājam un tādējādi ierobežo lietotāju brīvību. HTC šādu rīcību pamatoja ar vēlmi nodrošināt stabilu ierīču darbību.
What Is A Bootloader ?
In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. This is one reason that all Android phones have different Custom ROMS developed due to high variance of processing hardware present on the device.Android Phone Bootloaders ?
Every Android phone has a bootloader that instructs the operating system kernel to boot normally. But you need to understand one thing here that as Android OS is an open source OS and is available on a variety of different hardware, every manufacturer has their own version of bootloader specific for the hardware present in it’s environment.Why Is Bootloader Locked ?
A bootloader is usually locked on an Android device because although it’s an open source OS, still the manufacturers want you to stick to their Android OS version specifically designed for the device. In order to apply this concept, manufacturers lock the bootloader. With a locked bootloader on Android devices, it is virtually impossible to flash a Custom ROM and forced attempts void warranty as well as usually end up in bricks. Therefore, the first step is to always unlock the bootloader.Why To Unlock Bootloader On Android Devices ?
The explanation to this question is really simple. If you want root, you’d be wanting to flash Custom ROM post-root, and if you want to install a Custom ROM, you’d need to have your stock bootloader unlocked. In simple terms Unlocking the bootloader allows you to install custom Firmware on your Android phone.Avots: addictivetips.com
