I bought a oneplus 7. Tried installing e/os using easy install. I get stuck at unlocking bootloader. In the fastboot screen I am supposed to walk through the menu with vol up/down. But there is no unlock bootloader option there.
Thank you for your help
Regain your privacy! Adopt /e/OS the deGoogled mobile OS and online services
Currently on hold....First draft, very raw: How to successfully use e/OS/installer (web)
Install /e/OS on a OnePlus 7 - “guacamoleb”
Tip: The steps given below only need to be run once per device.
Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or an online drive
Warning: Some vendors/manufacturers prevent the bootloader from being unlocked. Depending on where your device was acquired you may or may not be able to unlock the bootloader. To verify if your device is compatible please check the devices list.
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
fastboot devices
5.Tip:* If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.
fastboot oem unlock
Thank you very much Pierro. Yes I tried that method. Got stuck to where it says
" fastboot oem unlock". The device is recognized but doesn’t restart after that command.
Instead it says “device can’t be unlocked for technical reasons”
Did you know about the device page of every supported device?
https://doc.e.foundation/devices/guacamoleb
Usually if a certain configuration works or not, it is shown there. Can’t see that for OnePlus 7.
How did you try ‘fastboot oem unlock’? Please write about the OS and from where you use platform-tools (adb and fastboot).
Used adb and fastboot from command prompt within the platform tools
Yes I walked through the manual. Found out this specific error has to do with a known problem.
I first have to rollback to android 11. But the rollblack files are removed from the oppo server. From android 11 I can do a oem unlock bootloader. So I seem to be stuck again.
Any suggestions on how the roll back or other ideas perhaps
Tried MSM Download tool but that give me a package error.
Can’t access rollack package page anymore
rollback
Hi @eosfan is this the same guacamole as in the link below? I will just pick this one quote. The thread at this point researches several sources of ROMs.
No this is a Oneplus 7 but not the Pro.
I found a way to still be able to download the rollback version using this trick
Rollback trick
I also downloaded this file [OPLocalUpdate] to be able to install rollback file.
(https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk) Have been using the same trick mentioned in that thread.
This is the command to use.
Alternatively, you can use the following curl commands to download rollback packages.
The format is curl -C - -LO --resolve oxygenos.oneplus.net:443:23.48.224.239 <url>
Doing it this way I managed to install Android 11.
After that I was able to unlock the bootloader. I am now in the proces of upgrading back to Android 12 again. Hope it does not lock itself again :-).
Hopefully this time installing e/OS will succeed. I will give an update on that.
update:
Everything worked out well. Followed the instructions for manual installation.
