touchscreen not working after updating issue - OnePlus 3 Questions & Answers

hi all, I own an op2 and decided to buy an used op3 for nfc and my idea was to keep it stock. op3 arrived and I turned it on, configure it and all seemed to work well (it came with android 6.0.1). then an update was detected and after reboot the touch was not responding at all, only hw and home keys. touch doesn't respond even in recovery, so in 5 mins I had a brick. I'm not a noob so I found some msm unbrick tools that full reflash the device, but the result is that if I flash a 6.0.1 image all works fine (touchscreen selftest all green and passed, handwriting test ok), if I flash one of the 8.0.0 images touch does not work! (don't have any Nougat image decrypted...). sideloading an ota produces the same issue, I tried to sideload ota001 6.0 (touch ok), ota002 6.0 (touch ok), ota010 6.0 (touch ok), ota020 7.0 (touch KO), ota070 8.0 (touch KO), ota073 9.0 (touch KO).
any tip? thanks

Stuck on "penguin" boot (RESOLVED!)

Hopefully someone can help me its for X800 china version
I tried to open the phone after 2 years, and tried to update it with official ROM from http://123.59.123.195/cn/download/phone/30
After updating, when I tried to reboot it, it got stuck on this black screen with a small penguin, and then after few seconds, it restarts back with the same black screen and the penguin.
I can still access TWRP recovery if I press the vol up button while it is restarting. I tried installing different custom ROM, but to no avail. I would really appreciate if you can help me fix my phone
EDIT: RESOLVED
It was looping on fastboot mode (the penguin icon)
Tried installing an older version, lollipop based, from Cuoco92 (from here https://androidfilehost.com/?w=files&flid=57901) and it worked again (thanks Cuoco92!)
Upon reading online, it seems the partition may have been corrupted since I'm trying to flash a MM ROM from a lollipop ROM ,without updating the firmware
I found out that I need to update the firmware to 16S, which I downloaded from this thread: https://forum.xda-developers.com/le...ollipop-marshmallow-firmware-x800-cn-t3463736
(thanks hugoprh!)
After that I am able to install any ROM, from MM and up (was able to install Lineage OS 14.1)

Did you change the screen or the digitizer in the past? Or drop the phone?
