Swipe to allow modifications. TWRP 8.0 OOS5

[ceanth]

Hi guys,

I have flashed Oxygen OS 5 onto my OnePlus3T and am rooted with Magisk.

Everything is working fine however when I boot into TWRP I get a message to keep system read only and swipe to allow modifications.

My understanding is that if I swipe to allow modifications then I won't be able to boot Oxygen OS5, and I read a guide which said to flash a dm-verity and forced encryption disabler zip.

I do not want to loose what is on my device so I am worried that if I swipe to allow modifications then I will be forced to format data on my device.

How can I allow modifications on my device but not be forced to format data?




Thanks

If you've already flashed Magisk, then it shouldn't be problem as the Magisk zip will disable dm-verity anyways. If you're really worried, you can swipe to allow modifications, then dirty flash OOS 5.0 and Magisk in the same session before rebooting.

Thats what I thought so im confused why im getting the message in TWRP.

So if I swipe to allow modifications and the device doesn't boot I can go back to TWRP and dirty flash or once I allow to boot and it fails then i'll loose all data?

If you swipe, dirty flash ROM + Magisk, then reboot and dm-verity prevents you from booting, then it means you've tripped it before. In that case, flash an old version of the bootloader (OOS 4.0 or earlier), manually disable and re-enable dm-verity through fastboot, and dirty flash ROM + Magisk again. There's a guide on how to do it somewhere in the forums. Either way, regardless if you trip dm-verity or not, it shouldn't delete any of your data.
