No root on LG Fino [LG L70pn (D290n)], why?

Hi there, i hope this thread is still alive and someone can help me rooting my Device LG Fino [LG L70pn (D290n)]. I got this old device recently as a gift, with the old kitkat (4.4.2) on board. It is updated to the latest system update available.

Baseband-Version: M8610B-AAAANAZM-1.0.6056

Kernel Version: 3.4.0+

Build-Number: KOT49I.A1452595206

Soft.-Vers.: V10g-EUR-xx

Tried the old PurpleDrake version and the newer one nothing seems to do the trick, i get always this output:

Please ensure your phone is connected, powered on, and USB debugging is properly enabled.
Your phone should be showing your homescreen with no other apps open. This is to ensure a clean state.

Alright. We're ready to go. We're going to temproot your phone first. Press enter when you're ready!

Temproot worked, all done here. Moving on...
Alright, now that you're temprooted, you can press CTRL-C here and get
a temproot prompt through 'adb shell /temp/fakesu' if you're so inclined...
However, if you'd like to permaroot, let's continue.

So, we temprooted your phone, but we weren't able to permaroot it for some reason.
Please post on XDA with your phone model, carrier, and SW version in the PurpleDrake thread and someone will take a look.
Your phone has been rebooted back to normal system mode, no changes have been made. Thanks for trying!

I need ROOT, without I can not install https://xdaforums.com/d290n/development/rom-cyanogenmod-14-1-lg-l-fino-t3514200

Are there other ways to root this device?

Update 1:

Found a solution here https://xdaforums.com/d290n/how-to/megathread-lg-l-fino-root-roms-mods-t3310862/post69699299 this seems to do the trick, i am now able to boot to twrp!

Update 2: THE DEVICE was STILL NOT ROOTED, but it was possible to boot to TWRP (adb reboot recovery) and install the latest version lineageos https://xdaforums.com/d290n/development/rom-cyanogenmod-14-1-lg-l-fino-t3514200

So the main question, how to root my device is still unanswered to me. I would appreciate, if someone has a solution for me...

Big Thanks to all Supporters & DEVs on XDA! :good:
