Firmware Chaos - Friend's P9 lite

Dear GUIDE-Developers,

as I was trying to fix a friend's VNS-L21 with originally flashed firmware: L21AUTC555B376 - I tried DC_Phoenix and then suddenly I had VNS-L21C185B150 (a Middle-East-Version complying with my friend's origins (=Iraq) and

PHONE UNLOCKED, but FRP LOCK

.. so, now I can flash any partition APART FROM: TWRP-Recovery (= which Could be useful?) in bootloader mode (Vol- & Power) yet Firmware update over Wifi did not work, and installing firmware as update.app via 'dload/-Method from micro-SD did not work, (resp. /hwota/HWOTA.zip ) .

Now I've got TWO IMEI-Numbers btw and checking emmc with:

fastboot oem emmc_diag

showed everything's OK..

So - what further steps can I take to avoid bootloop (phone boots up to the 'bubbles' and then reboot) - what partitions should I flash and which correct firmware?

THanks so much in advance ..

...= I recognized there was a mismatch between REscue-Version (L21C900B150) and firmware-Version (L21C185B150) but I do not dare flashing recovery nor boot because I'd seen some users here flashing them both and having a total brick ;-/
