Updating from 7.4 to 7.5 via OTA fails, according to this:

> [@FP4: Iode 7 status / Issue Tracker?](https://community.iode.tech/t/fp4-iode-7-status-issue-tracker/7653/84):

> OTA Update to 7.5 failed tonight and sent me to a “corrupt user0” bootloop. I do understand, after reading this thread, that this results from a FP bug, but I seriously wonder why Iode pushed this OTA update, apparently without testing (or at last a visible warning)?

And this has been reported to work out when stuck in a boot loop:

> [@Booting into recovery after upgrading to v7.x](https://community.iode.tech/t/booting-into-recovery-after-upgrading-to-v7-x/8139/14):
>
> Yes, almost. recovery → advanced → fastboot then fastboot getvar current-slot (was a for me) fastboot set\_active b fastboot reboot booted perfectly, now I set up nextcloud joy

But Updater app does not show an advice nor a warning.

Not the best situation.

Any official instructions from Iode?
