The most important role of Bootloader is thru FLASHING both using himaupgradeut.exe(nbf), “l” and “lnb” command in mtty.exe or even with SD Flashing (backup first your ROM in your SD/MMC with mtty.exe).

We use also Bootloader for other stuff like reading/writing the content of ROM and RAM. We use it for Backuping the ROM and some other stuff thats beyond the OS enviroment.

Technically there is no reason for changing your bootloader. Almost all bootloader performs as it with other bootloader.

But like the OS update, some bootloader is is not compatible with newer or even older ROM upgrade utility and need to be change if needed.

Currently there are Six ways to Change your BOOTLOADER in your GOOD old HIMALAYA but i’ve only tried four methods .. and to be exact none of them is safe ..

First Method is Changing thru nbf(HimaUpgradeUT.exe) - ALL nk.nbf contains a BOOTLOADER but some nbf has an emptied/Blank portion for bootloader and can cause for a brick device. But technically by default our devices is set to skip the bootloader during FLASHING. I really dont know how exactly but some upgrade can really change your bootloader (but only in HIMALAYA and BlueAngel Type I ROM, in Magician, BlueAngel Type 2 ROM and Alpine .. you can modify the nk.nbf to also write the bootloader but this method is the most dangerous of ALL method)..

Second Method is thru BootBlaster - ByteBlaster is design for changing the bootloader of Ipaq. I havent try it so i cannot make sure if this can really change the bootloader of HIMALAYA

Third Method is thru JTAG - technically it should be the safest method cause changing the bootloader is thru communicating to the chip itself so if you made it incorrectly then you can repair it again (unlike in other way that if you made mistakes once you already brick the device) but still it is the most dangerous way since you can totally damage the device. DO this only for the last resort

Fourth Method is thru mtty.exe(or Romupdate.exe) - in mtty.exe there are two commands you can use to change your bootloader

• thru “l” command (not i but small Letter L) – but you need a B000FF .bin files to do this, the command is just typing this in mtty.exe window:

l c:bootloader.bin

• thru “lnb” command – in this command you need now a RAW binary files of Bootloader the extension is sometimes use as .raw, .bin(raw), .nb0 or .nb, bootextract.exe can get a raw binary files of Bootloader in your device. The command is :

lnb c:bootloader.nb 80000000 00040000 0

Fifth Method is thru SD ROM Flashing - yes SD Flashing cannot only backup your OS ROM, Extended_ROM and Radio ROM, but it can Also backup your BOOTLOADER and as a matter of fact it can backup everything in your device and YES can overwrite it aswell. In Order to backup your bootloader in HIMALAYA you have to make this command in mtty.exe

d2s 80000000 00040000 -> Backup bootloader only

or

d2s 80000000 02000000 -> Backup Bootloader + OS Rom (HIGHLY RECOMMENDED)

Sixth Method is thru itsme’s PNEWBOOTLOADER.exe - this method is definitely the easiest and fastest method. Not to consider the safest method of all (but still DANGEROUS). Currently the pnewbootloader.exe is compatible to the following Device with the FOLLOWING OS ROM version installed.
