I've this problem when I make the rom in the log file:

[17/06/2021 9:07:01] [customimage] [create-image] [system/app/WearBluetooth/lib/arm64/libmtkbluetooth_jni.so] not found in canned fs_config, using defaults
[17/06/2021 9:07:01] [customimage] [create-image] [system/app/WearBluetooth/oat/arm64] not found in canned fs_config, using defaults
[17/06/2021 9:07:01] [customimage] [create-image] [system/app/WearBluetooth/oat/arm64/WearBluetooth.odex] not found in canned fs_config, using defaults

And a lot more like this for files that I added to the rom.

Also I've this error:

[17/06/2021 10:06:13] [customimage] [create-image] error: ext4_allocate_best_fit_partial: failed to allocate 81 blocks, out of space?

I've a lot of free space in hard disk.

How can I fix it?

Finally got magisk to work using this code.
I had to put
magisk.zip into util/root
busybox into crb/bin

# Flash Magisk
ui_print("-> Flash Magisk For Root");
package_extract_dir("util/root", "/tmp/root");
run_program("/tmp/crb/bin/busybox", "unzip", "/tmp/root/magisk.zip", "META-INF/com/google/android/*", "-d", "/tmp/root");
run_program("/tmp/crb/bin/busybox", "sh", "/tmp/root/META-INF/com/google/android/update-binary", "dummy", "1", "/tmp/root/magisk.zip");
Where is located for util/root folder? Thanks

CRB (Windows only)

Some versions of Windows do not support case sensitive. You can test it in CRB -> Settings -> Test WSL.
If it failed then go to <i> and follow the instructions.
Run CRB as Administrator.

1. Extract system.img
2. Extract vendor.img
3. Copy boot.img to ROM folder
(Or just extract ap....md5 to get all 3)

4. Make any changes
- edit build.prop to change ROM name
- use fast debloat text file method
- use debloat option with tick box
- add apps to system/priv-app
- tools- remove Knox & disable DM-verity
- deodex if you want

5. Build ramdisk
6. Build zip (wait a few minutes)
7. Transfer to the phone and flash with TWRP.
8. Further changes can be made to the zip file using zarchiver app.
So, I need to edit build.prop in system or build.prop in vendor? Or both of them? Please give me advise. Thanks mate.

    Eager to see CRB V3
    Already thank you for this great tool.

    But impossible to request the Test on Telegram.
    possible to have the link in MP by XDA?
    Hi @MrWaehere and hats off for your cooking, I have to work on the French translation if that tells you I could send you the file as soon as it is operational.
    Good continuation..View attachment 5370369
    Thank you very much, but version 2 of CRB is end of life. Version 3 is completely new and the translation is not compatible.

    I started development to update CRB to full support for android 11 and for all new devices. After all the requests that came to me, I decided to dedicate my free time to the update. It will take some time, but it will come! I hope you all enjoy it.
    Hello everyone! I apologize for my long absence. I'm working on a new project and I've been very busy and have no free time to develop CRB as I would like. As soon as I have free time I will resume development. Otherwise alternatively I will make all of the source codes available to the community in order to carry the project forward with development.
    ## [2.2.1] - 2021-05-15
    ### Fixed
    - Fixed android 11 vendor image extraction issue.
    -- How to install: extract ext4_utils.exe inside crb_v221b_fix_ext4_utils.zip and replace the existing one in Bin folder.

    Hey! Tool seems great but when flashing ROMs built via this(.br) , flashing gets stuck midway at "Patching system image unconditionally". Also, build rom zip file doesn't work for me (gets over in 3 seconds with no results), building dat file still builds in .br format and .br roms don't flash like I said earlier. Thanks.
    Device is Redmi note 5 pro, android pie ROMs.

    I'm working in new update version, that fix some bugs. I will release it in a few days! Can you try it later? Thank you very much for your feedback!
