I did take a look at the upgrade procedure fo unlocked bootloader here:

> [@Fairphone 4 update to iodéOS 7.4](https://community.iode.tech/t/fairphone-4-update-to-iodeos-7-4/8001/23):

> With an unlocked bootloader, you should just be able to install the advertised update from the Updater app. I am getting confused with the scenarios of what shows and what doesn’t, if it doesn’t show, then the OTA file can be downloaded (link at the top of this thread) and in the Updater app choose “3 dots \> local update”. No data reset needed.

My FP4 fairphone4 says “Your device has loaded a different operating system” on boot, as I have an unlocked bootloader (I remember not locking it).

I updated directly from 6.14 → 7.5 as described in:

> [@Upgrading 6.13 -\> 7.5 (unlocked bootloader)](https://community.iode.tech/t/upgrading-6-13-7-5-unlocked-bootloader/8147/7):
>
> I got confirmation that in testing 6.x \> 7.5 with an unlocked bootloader works fine for the FP4 using the OTA update. If an issue is encountered, do NOT reset your data but you may need to change the active slot. Let us know if that happens.

I still did run into the “Reason: init\_user0\_failed” after updating to 7.5.  
I tried to switch the “active slot: a” to “b”.  
Entered fastboot, run `fastboot devices` on my laptop, which did not show a device

Then after a few reboots it switched to “active slot: b” but still failed, and with the following boot it worked fine and booted back to 6.14

Any advice? Does this mean that my bootloader is locked? In fastboot I saw “secure boot: yes”..
