I want to flash the "newest" SimplRom (v5F) on a Galaxy Note 4 and the instructions say I need to also flash the modem and bootloader firmware at the same time.

Now I have three files: BL_N910FXXU1COI3.tar.md5, CP_modemCOI3.tar.md5 and SimpLite_v5.zip but I'm not sure how to flash them.

Most instructions tell me to use Odin, some describe the procedure using Heimdall. Odin is not an option for me (no Windows) and Heimdall seems to change it's user interface every now and then, so the instructions don't apply.

To make it short: is there a way to just use TWRP or dd (this worked for TWRP) to flash the files? I've found a lot of instructions but since there are so many different file types, recovery roms, devices, tools etc. out none of the instructions seem to apply for me..

Do I need a PIT file for the dd approach?

  • There's something called Mobile Odin, though I'm not sure if it's up-to-date enough to handle newer devices.

Important note: Hey guys, thanks for the upvotes but this answer turned out to not work at all.

The steps below don't break anything and this is why I thought I flashed modem/bootloader. You can use dd to make backups of the partitions below by swapping of/if but modem/bootloader won't be modified by the code I've posted..

In the end I had to fiddle with heimdall and boot the phone in download mode to actually flash the partitions.

Original answer:

In case anyone else wants to flash Bootloader/Modem and heimdall/fastboot/odin is not an option - this worked for me:

Extract/copy the files you need somewhere on your phone - e.g. with adb push ./bl_modem/ /mnt/extSdCard/, start a su-shell:

adb shell
> su
> cd /mnt/extSdCard/bl_modem/

then just flash the files with dd:

> dd if=NON-HLOS.bin  of=/dev/block/mmcblk0p1
> dd if=modem.bin     of=/dev/block/mmcblk0p2
> dd if=sbl1.mbn      of=/dev/block/mmcblk0p3
> dd if=sdi.mbn       of=/dev/block/mmcblk0p5
> dd if=aboot.mbn     of=/dev/block/mmcblk0p7
> dd if=rpm.mbn       of=/dev/block/mmcblk0p8
> dd if=tz.mbn        of=/dev/block/mmcblk0p9

Important: the provided block device names only apply to Note4/N910F. Have a look at the links at /dev/block/platform/msm_sdcc.1/by-name/ to find out yours.

I double checked these names by first making a copy with dd and comparing sizes. The sizes won't be equal to the sizes of the files you're going to flash but they should be about similar size.
