Thank you very much.
This means, you used ADB to unlock the bootloader but used the iodeOS included updater to install the update afterwards. I will try this.
Thank you very much… it worked perfectly.

Note that @vince31fr updated the situation here: Fairphone 4 update to iodéOS 7.4
In short, the method @parity and @beetroot followed by unlocking their device (which reformats userdata) and then installing, then relocking basically follows “option 1” that he describes: “clean installing the system”.
Option 2 is to install the update from Recovery, then when still in recovery, do a factory reset.
But the original guidance at the top of this thread hasn’t worked (to install the update from the “Updater” app, then factory reset afterward), so again this means a user needs access to fastboot via a terminal to either unlock the device or just fully reinstall, or to adb sideload the update from Recovery.
Sorry again for the difficulties, this Fairphone firmware bug has been very difficult to solve (effectively this process to reset / upgrade sidesteps the bug to move forward “past” it).
I have heard that Vincent will be elevating the priority to get the FP4 re-integrated in the graphical installer: this would at least allow a user to re-install without a terminal connection to their device (but it still will not preserve user data so if you are able to reinstall or “upgrade + reset” there is no reason waiting for the installer update will help).
Hi all,
Firstly, big thank you for all your guidance and effort. Special thanks to @rik , @vince31fr , @MissPiggy
Now just sharing my experience with updating:
- Succesfully updated via Sideload from Recovery (option 2 mentioned above).
- Previously, I made a backup using SeedVault for the applications (exceptions apply), and manually saving files, and app settings when those could not be backed up by SeedVault (Encrypted stuff), and, just in case, also for other apps like VLC, Pipepipe, OSMAND PLUS, … .
- After first reboot, I have minimally configured the phone (from scratch), connected to WiFi, During the process I am offered to restore a SeedVault backup, which I accept. After about 5 to 7 minutes, the process finishes, with only 2 apps showing a warning (Iode Browser and Thunderbird, as expected as per further above comments).
- Upon revising each app and settings:
- I found that OSMAND PLUS and COMAPS maps and settings were not restored (not sure if I ommited something upon backing up). I tried torestore them manually, as I made manual backups from the apps themselves. Some data are missing, I must have done something wrong
- Telegram FOSS version: does not recognize me, so no data were saved in the backup. I tried to configure it with anew (entering phone number ….) , but for the moment I cannot restore my account (something related to the FOSS version not allowed to be used as the first sign up …), I appreciate any help here
- ProtonMail: app crashes. I uninstall and install again, log in. Solved
So far so good then, with the exception of Telegram FOSS (help apprecited). Thank you again!

Last weekend, I took the big step and updated my Fp4 from iodé 6.x to iodé 7.4. The most important data, such as Messenger, email, the address book, and the calendar, were restored. I’ll install the remaining apps step by step.
I hope the update to iodé 8.x will work without having to reinstall!

Do you not have Telegram running on desktop or another device still that can “approve your new device”?
So I finally got around to upgrading my Fairphone 4 to Iode 7.4 and restoring the 20GB backup…
Let’s see if this resolves my battery issues.
Many thanks to the developers for still trying to get it right…

Battery life times three…

Battery drains 3 times as fast, or your run time is 3 times longer (so battery drains 1/3 as fast)?
Hah, I meant that it now runs three times longer with the same use. Like before the September upgrade.
Can you see why this upgrade was so important for us?

Unfortunately not. So I temporarily installed official Telegram app, just to validate my account via SMS, then went into web Telegram on computer, recovered my account there via internal message in official app, then uninstalled official app, installed FOSS version (which is now named “Fork”, I learnt in the process), and validated my account again, this time using web Telegram.
I did not expect this journey, but it is done now. I just fail to remember this limitation Telegram puts in FOSS implementations.
Thank you!
