[Please help] Can't backup Huawei Y3 II

#1

Hello community. I'm here to request some help about backing up my ROM since there is no official firmware launched for this 'recent' device.

Here are the specs:
Huawei Y3 II LUA-U23 (Double-Sim)
Processor: MT6582M
Chipset: Mali-400MP2
RAM: 1Gb

Initially I tried to do the backup with MTKDroidTools but I get "ERROR: Zero file, no space left on device!" with preloader and dsp_ even when I used a 16gb SD and installed busybox. I have to mention that I rooted my device with Kingroot (via pc 'cause apk didn't work) and had to install abdb insecure 2.0 to get Backup option  working.

Due that, I decided to use SPFlashTools dumping solution (readback) but I get stucked at "Error 0×7D4 Message: BROM ERROR: S_BROM_DOWNLOAD_DA_FAIL" and I couldn't go any further. Of course I've changed drivers, SPFlashTools version, pc, USB cord, checked battery level and everything seems to work but I had no luck with it. Sometimes when I unplug the phone SPFlashTools shows 0x7D5 error but I have no clue what could be happening. I really appreciate any reply to this topic 'cause I'm kinda worried about future bricks in my device.

Thanks in advance.

Ok, it didn't work. I spent almost 2 days switching between installing drivers and rebooting but I couldn't make it work. I even tried all guides supplied in this thread https://forum.hovatek.com/thread-13498.html and same error:
Waiting for USB Port...
Waiting for USB Port...
>>none usbport, maybe driver not installed

What could I do next?

what does the phone get detected as in Device Manager when you switch off and connect to PC

Phone gets detected by Device manager and makes the plugged sound but it disconnects almost 1 second later and starts charging. It does the same with all drivers I tried.

You'll need to apply the connection-disconnection fix @ https://forum.hovatek.com/thread-439.html
you should be at Device Manager immediately you connect and scroll down to Ports to see what has newly appeared

I had no luck. This is strange. My Older devices don't show related problems with connection. Even I went wild and tried with fastboot mode.

Now I'm going to try with some virtual machine running XP.

Problem solved: With SpFlashTools I could make the backup. I only had to change the download agent from another source. I hope you add this solution to SPFlashTools common errors.
