So once you have the bootloader unlocked (and the device SIM unlocked), then Magisk "roots" the OS for you? Is that all I was missing all this time, lol?

Obviously back up the important partitions first in case something goes wrong, but was I just overthinking the process this whole time?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] xen423:
Have you flashed TWRP? Or any other Recovery? If so then yeah, Magisk does the rest. Just flash the apk or zip in TWRP.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] silentrawr:
Yeah, flashing TWRP was the first thing I did once I got the bootloader unlocked. Anyway, thanks for the explanation! Here's hoping I don't **** it up ;)
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] silentrawr:
Ayyyyy, I didn't bungle it! Now, to figure out which apps keep tripping up TB, and to find a new camera app that doesn't suck. Thanks for the help!

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] silentrawr:
Good **** man, ty again!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] silentrawr:
Something wiped out my fingerprints, though - could that be due to SafetyNet getting messed up because of Magisk? It's strange, because the option is still turned on at the lockscreen, but when I try to use one (or set up new ones), the existing prints are gone.

Trying the light theme + max brightness, but I'll search around for anything else that might cause be causing it.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] kjslabber:
You can try this cam. Not to bad, posted on telegram gtoup.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] AxxPyrtlexx20:
Gonna be releasing a new build this weekend. Alert Slider big has been fixed & same with audio issue in certain apps, other goodies were added as well!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Spacewulf:
XDAs searching is a bit of a nightmare, so I was unable to find anything about the FOD. I just flashed the rom and it's running quite smoothly although the FOD doesn't always seem to want to activate. I'd assume this is known, but is there a fix at the moment?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Diakow:
I have an error sideloading this ROM. Either is 'cannot read ROM.zip' or installation failed by 47% WITH 'SIGNATURE FAILED' notification. Using provided recovery and last OOS as base. This is strange, beacuse I have installed Pixel Extended ROM with no problems. Downloaded DerpFest several times, by the way downloading speed is very slow.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] AxxPyrtlexx20:
Did you hit yes on the phone?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Diakow:
Where? In recovery? I selected Install from ADB and then 'adb sideload ROM.zip' in cmd on my pc. Even when it worked, it halted by 47% saying 'signature failed' and 'error'. Using lineage-18.1-20211028-recovery-kebab.img.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Spacewulf:
Interesting. I'll have to look it over again.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] kjslabber:
You need to give permission to finish, hit yes on phone at that point.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] AxxPyrtlexx20:
How did you flash derp?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Spacewulf:
As instructed in the initial post. First came from OOS11 for widevine L1, then flashed recovery, wiped, sideloaded, and booted.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Spacewulf:
Nvm I didn't do it right. I'll try it again soon, sorry for that.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Spacewulf:
Alright, I followed everything from the first post, and still, FOD isn't always working, it's really a hit or miss as to whether or not it works.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] JTC3:
I just flashed this rom today, I LOVE you guys lol This Rom is an absolute beast and runs awesome. Super smooth, plenty of customization and that Pixel experience mixed with Oxygen, couldn't be happier
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Okay686:
So, what's your rom version now? You had better flash derpfest based on OxygenOS.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] JTC3:
I actually had that same issue when I did mine. Flashing the recovery first in Fast Boot, then going to recovery I flashed the rom and had a signature error, I opted to install anyway, waited a while, and got an error message at 47%. I ended up just resetting the phone after it finished and it booted fine. Could be a normal thing (This is from the installation guide of Pixel Experience) Reference link: https://wiki.pixelexperience.org/devices/kebab/install/
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Okay686:
Yes,47% and 'No error' is okay.

Anyone have experience going from crDroid to DerpFest? I like crDroid but it seems to be a smaller community (at least for this phone). A bit harder to get help if needed. Outside of crDroid, I only used stock OxygenOS so I dont have much experience.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] gforceriders:
Yes, I came from crdroid to Derp. I flashed Derp by flashing the orangefox img then wiped internal data and used a OTG to flash derp and orangefox zip. You could also sideload with the recovery on the first page but will need to wipe internal before sideloading. Either way you will need to wipe internal data.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] morphius88:
How does Derp compare in the features and customizations to crDroid?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] gforceriders:
Pretty much the same as in features but battery is better and more smooth overall. Give it a try and you will be happy.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] morphius88:
Will do. Thanks

Amazing! Just saw an update on the system updater. Took me here! Great work dev.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] coomac:
Had the same problem. The super partition (7gb partition containing system, system_ext, product and vendor) doesn't have enough free space.

Run "fastboot delete-logical-partition <name>" from fastbootd to delete some of the sub partitions. For example "fastboot delete-logical-partition product_a" to remove product_a.

After deleting, recreate the partition with "fastboot create-logical-partition product_a 100000". The number is the size of the new partition in bytes - any arbitrary low number will work since the partition gets resized to the actual size of the .img file when flashing.

Make sure you do the same for both a and b slots. I ended up deleting and recreating system, system_ext, product and vendor but you only need to delete a couple to free up enough space.

This problem occurs because Windows has not installed the drivers because it does not recognize the drivers signed by Microsoft. You have to disable checking for signed drivers at Windows startup.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] sakun-ice:
Sometimes the whole procedure may seem confusing, but it really is not difficult. The summarized steps to root are:

- Extract payload.bin from the zip file of the ROM you have installed.

- Extract the boot.img from the payload.bin file (I use payload dumper go for this).

- Transfer that boot.img file to the phone and patch it with the magisk application.

- copy the patched file to the pc.

- flash it with fastboot (fastboot flash boot magisk_patched_boot.img)

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] manish.r.silwal:
Kudos to the developer for making this awesome ROM.

I found a few issues in this though:

I couldn't set up a separate work profile in this ROM. I can see that I can log in to a Microsoft work account and set up a work profile but there's no such option for a G-suite work account. Is this a bug or did I miss something?

The app drawer icons and home screen icons are different, meaning, the drawer icons are not changed according to the home screen ones.

Other than these, the ROM is working perfectly, and sure, if there are any more issues I'll post them.

Thanks to the developer for the awesome work!

quick question to this...

can you force to flash boot patched img to either the a or b partition?

I'm currently on a, the file i extract is from a, yet it seems to flash to b via fastboot.

How does the know which one?

the a/b setup have been a bit confusing 4 me.

any pointers to that?

thanks for any info.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] sakun-ice:
It is always installed on the active partition, unless it is installed from magisk and it is specified to be installed on the inactive partition. Likewise, these doubts are better to ask in the magisk thread dedicated to it.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] AxxPyrtlexx20:
it flashes to the opposite slot
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] racenrich:
thanks for the replies!; yet still abit confused.

i dirty flashed this to do the update and all worked well outside of losing root.

its been rough getting it back. magisk app is installed but the Magisk itself install only allows me to patch the image. done that, but on flashing as mentioned is on opposite slot and wont root.

did i miss something? again thank you for the information and support.
