Possible to reduce bootimg size or resize /boot?

[EliCh]

Hi everyone,

I have struggled for days to revive my old device (Huawei MT7 / PE) with Ubuntu Touch. And finally passed the compilation.

However, what bothered me is that the output halium-boot.img is of size 17700864 while partition /boot is of size 14680064.

Are there any way to resize eMMC blocks of Android devices?

Or are there some drivers unnecessary for Ubuntu that I can remove them from kernel?

Any other ideas are welcome.

Thanks at all !

Hi and welcome @elich

If I understand (at least a bit) your post, you're trying to port Ubuntu Touch to your device (Huawei MT7).
So I moved your post to the porting category.

Thanks for your efforts to bring Ubuntu Touch to a broader public..

@elich
Did you previously install a custom rom on this phone ?
From then did you reinstall last halium compatible factory rom on the device (the one you based your port on)?

I am not an expert but as far as I know it should be possible if you can flash TWRP to the phone first ?!

I have seen some posts in the past where some guys were messing with the partitions of a phone and I think they were succesfull...

Please check XDA Developers Forum for more information and as always : Good luck!

@keneda Currently a cm-based MIUI OS runs on my phone but this is my first trail to porting halium boot to a device

@nero355 Thanks for your suggestion !

I heard that TWRP is useful but I found it provides partition tool only for ext4 blocks ...

I am trying to understand how it modify DPT however reviewing source code is a hard work ...

[EliCh]

Oh it seems that I have post a stupid question ...

After searching, I learned that there is an adapted version of gparted (named parted or parted for Android) to edit DPT.

Whence it is easy to remove and remake partitions, just like working on desktop systems.
