Hi, after updating my Fairphone 4 from IODE 7.4 to 7.5 via the updater, Android cannot start anymore. Is there a way to start it again without a factory reset and losing all data? Any help is very appreciated! Thanks ![IMG_20260509_090306](https://community.iode.tech/uploads/default/original/2X/d/d1c6e7808cbd584ccdc7e45340c18af7e7b060be.jpeg) ---

Try to restart it several times, it should trigger a switch back to the previous version. ---

Thanks. I tried it several times already. Can the switchback to 7.4 be triggered manually? ---

❤ I just tried it one more time (in total approx. 5 times), and now it started with 7.4 again! ---

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”.. ---

Interesting, entering Recovery (holding volume down during (re)boot) shows: SECURE BOOT - yes DEVICE STATE - locked So my assumption that my system is unlocked was wrong. Great that I could recover to the previous version. Then I’ll do the fresh upgrade in the future. ---

Just for others that are still stuck I am linking to a new thread to consolidate the current status and issues: > [@Fairphone 4 iodéOS \`7.5\` update clarification](https://community.iode.tech/t/fairphone-4-iodeos-7-5-update-clarification/8168): > > There are several different threads discussing FP4 issues either going from iodéOS 6.x to 7.x and/or 7.4 to 7.5. I will try to make some baseline / clarification points here that consolidate the issues: then I will link here on the numerous threads and we can go from there depending on the specific case. First, the case still remains that if your FP4 is bootloader locked, you will need to either do a factory reset and update install from Recovery or instead do a clean install again: [Fairphone …](https://community.iode.tech/t/fairphone-4-update-to-iodeos-7-4/8001)
