sudo fastboot erase system will erase the system partition. When you will use sudo fastboot flash userdata hikey970-lebian9.img it will first erase the userdata partition and then flash the image to that partition. So don’t worry about erasing the ufs
Has not worked, the system has not loaded the login screen. I have returned to flash and still have the image but with the sdd12 with 4.6 g 
As I said, now that I have nothing configured, as I could delete all partitions and that the resized I left with the 64g?
edit. Maybe modify the image wrong, the image you were referring to was boot-hikey970.uefi.img or was it another?
Here in the link is the image which supports 25GB userspace

After booting resize the root file system by using: sudo resize2fs /dev/sdd15
I did not pluck after flash with configuration 1-0-1-0; The 1-1-1-0 does not recognize windows and when trying to flash Ubuntu (through virtual box) is not running, I’m not lucky 
…
You will not have the drivers of the board by chance?
In your ubuntu vm install android-tools-fastboot using apt. After that do the steps that I’ve written above after installing the image from the drive
Nothing I tried with the 18.04 and 16.04 LTS and uninstalling Modemmanager as it says in the instructions and I left KO flashing the image (always 1-0-1-0) because in 1-1-1-0 does not recognize the system Hikey
Did you run recovery flash.sh mentioned in post 20 ? Follow the steps in post 20. They work perfectly fine. The script automates all the steps and it can even recover a bricked board.
If that I did but in Windows does not recognize me the plate well and to load on VirtualBox I hang up when I flash the RFS system. Probe several times and nothing (in mode 1-1-1-0 as you said).
In mode 1-0-1-0 works well even in Windows, which is where I do and is faster.

How do you do resize2fs with “Hikey 970 Lebuntu”?
It seems rootfs is not on /dev/sdd15
Thanks,
I downloaded the image from the Lemaker’s site and I have already done the required changes to the image as well as the scripts. Although I didn’t test the image, Please try it out and let me know if it works.
Please flash the script flash-all-binaries.sh. Instructions to flash the script will be given in the flasing_guide.txt.

I have changed the root to sdd15 with Lebuntu, following these steps:
Step 1. Edit the grub.cfg in the boot image
sudo mkdir /mnt/boot-hikey970
sudo mount -o loop boot-hikey970.uefi.img /mnt/boot-hikey970
sudo nano /mnt/boot-hikey970/boot/grub/grub.cfg
Change sdd12 to sdd15 and gpt12 to gpt15.
sudo umount /mnt/boot-hikey970
Step 2. Edit the flash script
Change from
fastboot flash system leubuntu-16.04.img
to
fastboot flash userdata leubuntu-16.04.img
Step 3. Flash and reboot, use resize2fs to expand the partition
sudo resize2fs /dev/sdd15
Here is the boot image I changed:

Your boot code works with resize2fs.
Does any know OpenCL support on ubuntu image? When I run clinfo, the response says there is no OpenCL device. Any idea how to enable opencl?
Thanks,
The ubuntu image is missing the userspace drivers and hence, clinfo shows no platform found. I tried running clinfo on the debian image on the lemaker website and that works.

Is it possible to reuse opencl driver from Debian to Ubuntu?
If yes, how to do it?
Thanks,
Does anyone know how to set cpu clk? I have tried to adjust
/sys/devices/system/cpu/cpu4/cpufreq/scaling_max_freq to 1.84Ghz on core 0-3, but system keeps resetting to back to the lowest value, 509Mhz
Thanks,
Yes, it is possible. You need to copy the user space binaries and place it correctly in the rfs. Also you have to point to libmali.so. You can see how to use opencl for 960 to get more idea about it.
Is there any one who saw grub menus…
I installed leubuntu on hikey970.
It works well…
But the problem is no out put between booting and login(shunya).
I want to see and choose grub menuentry…
Is any one do that??
grub is visible on the serial console.
