I am getting the same error as this, what should I do to fix it?
Have installed python v2.7.13+3.6.1, latest java jdk and jre and .NET framework v4.7 and running windows 10, it had worked on the first try but started showing this error suddenly.

It works, but after install ROM the battery discharges very quickly and heats up... I think that incorrectly exposed file permissions, because if i flash "system" folder with setting simlinks and set_metadata in updater-script ROM works fine and battery is ok.
ROM work only with system.img, system.new.dat dont flash, error 7 in TWRP...

best tools ，thanks！！

The link is not working.
You need to have a custom ROM, and in it system.transfer.list and system.new.dat.
Use this method:
[DEV] sdat2img 1.0 - img2sdat 1.2 ◦ Unpack/re-pack android DAT files
For a long time I use and have not found Android ROM 5.1.1 - 8.0.0, which can not be unpacked using sdat2img.py.
Thank you authors @xpirt , @luxi78 , @howellzhu !

You dont need a custom rom or the system.transfer.list, or system.new.dat. This unpacks images just fine. It will not unpack factory images tho. I got it to work just fine unpacking nexus 6 system.img by placing the image in the output_converted_dat_to_ext4 folder then telling the bat file what the size is and unpacking it. Do the same thing for oreo and the ext4 exe crashes.

rom isn't booting after editing system.new.dat. any help ?

For anyone having syntax errors converting systemsparse.img to system.new.dat just download the updated img2sdat files from the link below and extract all files ending in .py to the tools folder of this batch tool. There's also an updated sdat2img.py linked below which goes in the same tools folder. Overwrite all the old files when prompted.
Edit: I've attached a zip that has the tools already updated. Maybe the OP can update the first post?

1. what this lines mean in an updater script :
run_program("/bin/7zr", "x", "/data/system_boot.7z", "-y","-o/system");

but what are "x" and "-y" and "-o"???
2. and how can i to convert two folders content to system.img and data.img to flash with fastboot?

[REQUEST] Build system.img

Hello,
I have an ASUS K01A tablet with a blank system partition and unusable recovery. I can flash img files to their respective partitions just fine (boot.img, droidboot.img) in fastboot, but 'system' in the stock firmware zip is a directory instead of a flashable image. Of course, this (and other reasons) means I can't just flash the stock firmware in fastboot, nor flash over the entire 'system' directory.
I need a system.img to recover my tablet from softbrick, but I can't for the life of me compile one. I've exhausted every method and tool I could find in both Windows and Ubuntu.
I beseech the community; if there is anyone reading this who could build such a file for me, I would be eternally grateful. I believe I only need the system.img to recover the tablet.
The stock firmware is at the ASUS website. Here is the download link: UL-K01A-WW-12.8.1.41-user.zip.
Thanks in advance!

Why not extract the system folder of the ZIP linked to, then pack it into a ZIP what you then convert to IMG using an online-convertor that does the job?

"Why not" indeed; that sounds like it would more than suffice. Can you please recommend one?

Anyone? I have been unable to find this "online-converter" despite days of searching; still at square one.

Only as example ( found via Google search !!! )

Thank you, but I've tried this one and all the others on Google, and none will handle the filesize (~650 MB). It must be purpose-made for Android .img files it seems, which I've been unable to find.

I built it finally using IMGBurn to create the raw img and Sparse Converter to convert it to sparse img fragments.
But now the tab has formatting error, and with -u option, flashing errors (all partitions and imgs now). Ah, well.
Thank you to everyone! Hopefully someone else reading this will have better luck than me.

Download the attached file from the link at the bottom of this post and unzip it somewhere on your PC. It is a temporary recovery launcher. We'll come back to it in a moment. Based on your original post I'm assuming you already have your stock firmware downloaded as well as ADB and Fastboot setup. From your stock firmware unpack the following files: fastboot.img, splashscreen.img, and boot.img and place them in your ADB/Fastboot folder. Copy the stock firmware to your sd card (in its original, unzipped form...the way it was when you first downloaded it). Put the tablet in fastboot mode. Run the following fastboot commands from a command prompt.
- fastboot flash fastboot fastboot.img
- fastboot flash boot boot.img
- fastboot flash splashscreen splashscreen.img
Reboot back to fastboot mode. Go to wherever you unzipped the temp recovery that you downloaded earlier. Double click on launcher.bat. Type accept in the window, then type T2 and your device should boot into CWM recovery. Now choose install zip>install from se card>and choose the stock firmware.zip that you previously copied to your sd card then let it do its thing. Once its finished go back to the first page of the CWM recovery that you're in and select reboot system now>no>no. You should be golden now. Post back if you have any issues.

Can't extract boot.img from Fastboot ROM file

I need to get the boot.img file to root my phone, but I can't extract the boot.img file from the Fastboot ROM file.
My phone: Omix X400.
Android version: 11 (R).
It has Seamless Update feature.
It is impossible to find custom recovery on the internet because my phone is not very well known.
Fastboot ROM File: https://github.com/omixmobile/firmware/releases/download/V11.4.2_X400/R.X400.20221116.V11.4.2.pac.xz
Optional: I have attached the system's build.prop file.

Didn't even know this device exists but was interested in your problem (having only Samsungs+LG).
Downloaded ROM from your link.
Searching!helped me find a youtube video how to extract files from that .pac file.
Downloaded that tool and extracted a file I suspect it to be the boot.img although named dtbo.img. It's 8MB big so I will not attach it.
Extracting is that easy that I believe you can do it yourself.

Bu cihazın var olduğunu bile bilmiyordum ama sorununuzla ilgileniyordu (yalnızca Samsungs+LG'ye sahip).
Bağlantınızdan ROM indirildi.
Aranıyor! bu .pac dosyasından dosyaların nasıl çıkarılacağına dair bir youtube videosu bulmama yardımcı oldu
Bu aracı indirdim ve bir dosya çıkardım, adının dtbo.img olmasına rağmen boot.img olduğundan şüpheleniyorum. 8 MB büyük, bu yüzden eklemeyeceğim.
Ayıklamak o kadar kolay ki, kendin yapabileceğine inanıyorum.

What for??
It worked/extracted all.

Any update to this? I am trying to get boot.img from a Lenovo .pac file, but it doesn't exist after the SPD extraction. Only dtbo.img, but Magisk fails to use it and says "Unsupported/Unknown image format".
All the other *.img files in the ROM do the same.
