Please add your suggestions to improve the documentation for the OnePlus - OnePlus 7 (beta) - guacamoleb here …
The “TWRP”-link in the “Downloads for the guacamoleb” does not work. The original TWRP page for guacamoleb (OnePlus 7 (guacamoleb)) links to the download section of the OnePlus 7 Pro “guacamole”. However, please note that I just bricked my phone by flashing the image-file for the OP7 Pro. I’m not sure if this is the common result or if I was too incompetent… Anyways, one should at least comment on which version to download.
Cheers
That’s useful info for the e team to correct the docs but mainly I reply out of concern that you may have a non booting device; or did you recover the install attempt?
I looked at the proper twrp page you linked to and it looks like a unified twrp for all the OP7 series so it should work ok
Another potential problem.
Installation doc for OP7 ask for updating the stock android to latest available. I believe this would be android 11
eOS ROM is android 10
I’ve just installed e/os on my oneplus 7. Seems to work well so far however it’s still at Android 10 not 11 as the instructions indicate. I wonder, are there plans to upgrade it to Android 11 then 12?
Installed Android 14 (U) ‘guacamoleb’ on the Oneplus 7 (GM1903) yesterday. The documentation reads to first be on the latest Android and then to run the OEM unlock. The issue is however that then the Android 12 OxygenOS you run on, gives this issue, due to a bug introduced by Oneplus:
fastboot oem unlock
FAILED (remote: 'Device cannot be unlocked for technical reason.')
fastboot: error: Command failed
The only solution is to rollback to Android 11, using their rollback tool:
https://community.oneplus.com/thread/1181216999612088323
The next issue you run into is that Oneplus changed their download links to another place, so you run into a:
Error code: 404 Not Found
To solve this, You need to add “https://s3.amazonaws.com/oxygenos.oneplus.net/” before the name of the file you want to download and the downloading will start. Or use a CURL.

After applying the rollback as follows:
* Download the latest ROM rollback zip package from the specified server.
* Copy the ROM rollback package to the phone storage and rename the package according to different regions, you may refer to the note below.
* Go to Settings -> About device -> Version -> Click Build number 7 times and enter the password, now you are in the developer mode.
* Go back to Settings -> About device -> Up to date -> Click the top right button -> Local install -> Click on the corresponding rollback package -> Extract -> Upgrade -> System upgrade completed to 100%.
* After the rollback is complete, click Restart.
* Rollback successful.
You can proceed with the fastboot OEM unlock on the stock Android 11 that will popup after the reboot. No need to upgrade to stock Android 12 afterwards, you can just install e-2.9-a14-xxxxxxxxx-community-gucamoleb.zip. Wish I knew this before, took me hours to figure out.

Interesting. I upgraded back to 12 after I did the roll back. Did not know it was not necessary cause it says in the manual minimum requirement is 12.
