PC cannot detect phone in TWRP mode only

[jula182]

I hope someone haven't post this question yet because I already try to search on google about this but there's aren't any solution for it yet.
I bought Huawei P10 Plus 256GB from China (VKY-AL00) and I want to changed it to International firmware but when I boot to TWRP recovery my laptop can't detect the phone. I even looked at Device Manager but there 's nothing happen when I plugged the phone. If I boot normally or fastboot mode, my laptop can detect the phone and I able to access the files from internal/external storage. I tried to flash update.zip, update_all_hw.zip and update_data_public.zip directly using TWRP but it only giving me "error 9".

My phone spec:
-Huawei P10 Plus 256GB (VKY-AL00)
-Storage type: UFS
-ROM Version: 8.0.0.336 OREO
-twrp 3.2.1-0 oreo 2 version

I have the same issue with error 9 and TWRP doesn't support USB yet for Oreo it seems. I think the problem is TWRP is reading the folders as encrypted on the update section (folders show as random characters) but seems to see folders somewhat in the File Manager. I'm sure this is a work in progress by the fine folks in this forum as TWRP website doesn't show the P10 Plus.

What I did was flash back to Nougat using HWOTA, then back to Oreo also using HWOTA. Had to do this a bunch of times through my experimentation and it works well enough to get a clean Oreo install that accepts Huawei OTA updates. Both links are for a different model but I'm sure there's something for AL00, just want to you know what worked for me with the L29.

Download both the update and downgrade from Firmware Finder, I tried the DNS method but with TWRP it won't work. Download it, but make a copy because the HWOTA2 script from the downgrade removes the update.zip at the end (didn't bother trying to find out why, I just copy it back in when I need it). When I used the firmware in the links above I wasn't able to update through Huawei OTA, the firmware from FF with checking access before download gave me the best results.
