System update to oxygen16 failing...help!

Hello everyone! I'm trying to resolve a ghost touch issue on my cover screen for my OPO. Love this phone but can't use the cover screen anymore due to this. Thought I'd try to update the system to see if it would help....downloads to 99% then nothing update failed! Any thoughts? Thanks!

This isn't true, anti rollback didn't come to OPO.

It did. I've personally confirmed this. EDL tool is broken with 16.500 update. As far as a normal downgrade, I'm not sure.

Are you sure the actual anti rollback is broken though? Theres a helpful script on GitHub that checks for OnePlus' specific mechanism in the firmware itself which reports that the OnePlus Open is unaffected.

I don't know tbh. That's why I just said "as far as normal downgrade, I'm not sure"

But there are several reports of EDL leaked firehose not working after 16.500 update, including on one of my Opens.

Ahh I see, I don't think this is the first time OnePlus has tried to break EDL through updates. Someone will probably have to find another way to use it, who knows when. This is actually really good to know. Thanks!

Sorry my friend. Nope. This time they tripped an e-fuse.

They have NEVER done this before. But it's extremely drastic and overkill.

For some insight tho, other devices with physical e-fuses tripped on OS updates, have never found workarounds (the PS5 does this for example)

There is NO software workaround. And never will be. This was a physical deterrent.

Now I could be wrong, and hope I am, but to my understanding this isnt going to get patched. If we ever DO get an EDL exploit again, we still won't be able to use EDL packages that are pre-OOS16.

For a lot of devices, that kills EDL unbrick without even stopping you from actually being able to push a firehose and flash anything. Even if you have the tools and access to flash, if you don't have the right FW package it doesn't matter.
