Need help to get bootloader

[seskanda]

Hello

How is a bootloader available as a tar.md5 file to flash in Odin? Is it possible to take the bootloader out of a Stock or Rooted ROM? Does it come from the boot.img file in some way ? Any help would be great.

Thanks in advance

Fixed title of the thread, but this is a general Android question and not for a specific phone so I hope it is in the right section

... not for a specific phone...

Not really, odin is a Samsung only tool.
So you must have a Samsung device.

And most android devices, the bootloader would need to be unlocked, to pull a copy of the bootloader.

Wow I had no idea Odin is a Samsung only tool
Yes it is Sprint Galaxy S5, does thread need to be moved now?

I see is any way to know if the bootloader is unlocked? And if not,
then can it be done?

If device's Android is rooted a device's bootloader typically gets extracted by means of a Windows CMD script what is simlar to this one

adb devices
for /F %%a in ('adb shell "su -c 'ls -l /dev/block/platform/msm_sdcc.1/by-name/boot'"') do (set blk_device=%%a)
adb exec-out "su -c 'dd if=%blk_device% bs=4096'"  > "C:\boot.img"

My Sprint Galaxy S5 is rooted what kind of file does this command output? Is it an IMG file? I'm looking for a TAR.MD5 file, and need it from a firmware/ROM that is not on the phone.

A tar.md5 should just be a text file for the checksum from the .tar file you are trying to flash?

I'm not really sure but let's say you are right I will be needing at least a .tar file of the bootloader from a firmware/ROM

I would look for firmware for your exact model here something like SM-G90xx

A TAR.MD5-file ( used by firmware update and kernel flashing applications like Odin and Heimdall for Samsung Android devices ) contains a TAR archive that has been verified with an MD5 checksum; the TAR file contains firmware and other system data, while the .MD5 extension verifies that no data is corrupted.

Ok it is SM-G900P w/ Android 4.4.2 NE5 rooted and Knox 0x0. I'd like to upgrade to Android 5.0 OA6 and keep Knox and root.

Yes that is a good explaination of what the TAR.MD5 file is. I'm never able to find a TAR file without MD5 as that verifies it. I've read that to upgrade to Android 5.0 with root and Knox may need a TAR.MD5 of the bootloader for the OA6 firmware. I have OA6 ROM file but no clue how to get bootloader from it.

 

[jwoegerbauer]

If a .TAR.MD5 suffixed archive file is needed, then change archive file's .TAR suffix to .TAR.MD5

 

[seskanda]

I do not have a .TAR or .TAR.MD5 file of any bootloader and that command you gave does not work it says "%%a was unexpected at this time" after the second line.

 

[jwoegerbauer]

Put the code example shown above into a Windows command file ( .BAT-file ) and it should work.

If ROM comes as .ZIP-file then extract the .ZIP-file with any ZIP software: the boot.img file should be right there at the root of the archive.

No, I get 'error: closed' when I run the .bat file as Administrator and it outputs a boot.img file that is 0 bytes in C:\

Yes the OA6 ROM is a ZIP file that Windows is able to open by itself, and I see a boot.img file in there. But even if this is the boot loader how can it be turned into a .TAR or TAR.MD5 file to flash in Odin?

Ok let's say I make a .TAR file from boot.img all I have to do is rename it to TAR.MD5 and Odin will flash it ?
