Hello,

I am experimenting with building TWRP from source myself.
But I am hitting an issue with the image being larger than what I can fit into the recovery partition.
I noticed the Online TWRP Builder has the ability to reduce the size. https://www.hovatek.com/twrpbuilder/

Can I ask how is that done?
I would like to use the same technique on my build.

I have tried using some build flags:
TW_EXTRA_LANGUAGES := false
TW_NO_USB_STORAGE := true
TW_EXCLUDE_MTP := true
TW_NO_EXFAT := true
TW_INCLUDE_FB2PNG := false
TW_EXCLUDE_TZDATA := true
TW_EXCLUDE_NANO := true
TW_INCLUDE_DUMLOCK := false
TW_NO_BATT_PERCENT := true
TW_NO_CPU_TEMP := true
TW_INCLUDE_INJECTTWRP := false
TW_HAS_DOWNLOAD_MODE := false
TW_NO_HAPTICS := true
TW_INCLUDE_NTFS_3G := false
TW_EXCLUDE_TWRPAPP := true
TW_NO_LEGACY_PROPS := true
BOARD_HAS_NO_REAL_SDCARD := true
TW_EXCLUDE_SUPERSU := true
TW_INCLUDE_CRYPTO := false
TWRP_INCLUDE_LOGCAT := false
TW_OEM_BUILD := true

Not only am I not entirely sure what some of these do, but it is removing a lot of functionality.

This got me from about 18MB to 12.8MB.
The compiler still complains though.
recovery.img maxsize=10454400 blocksize=135168 total=13434880 reserve=270336
recovery.img too large (13434880 > [10724736 - 270336])
ninja: build stopped: subcommand failed.

The original revovery.img from the ROM is 9.9MB
I have verified I can flash hovatek's slightly reducer 13.6MB twrp. Though I do not know how is that possible since the partition size appears to be smaller.

18MB is too much though and the the flashing fails.

Are there any other techniques that I can use to compress the recovery without loosing so many features?

Thank you and have a nice day.

You could leverage compression
e.g

LZMA_RAMDISK_TARGETS := boot,recovery
BOARD_RAMDISK_USE_LZ4 := true

or switch to Toolbox
TW_USE_TOOLBOX := true

Thanks. I will test this out.
LZMA_RAMDISK_TARGETS := boot,recovery
BOARD_RAMDISK_USE_LZ4 := true
These go into BoardConfig.mk?

Is there somewhere a list of all the flags that can be used?
I was not able to find anything.

I have tested it and the image does not want to boot.
Can I somehow check that lzma is supported by the device or use a different compression method?

It does boot if I use just:
TW_USE_TOOLBOX := true
TW_EXTRA_LANGUAGES := false
TW_OEM_BUILD := true

Try

Code:

TW_USE_TOOLBOX := true

TW_EXTRA_LANGUAGES := false

TW_OEM_BUILD := true

LZMA_RAMDISK_TARGETS := boot,recovery

Some flags cause problems when combined and those like BOARD_RAMDISK_USE_LZ4 := true tend to require additional flags
