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)
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.
