Sorry, I'm creating a new question for this old issue, as old solution doesn't work anymore.

Could not re-enable dev mode again (same issue with XperiaX and Jolla phone)

XperiaX: SFOS 2.2.0.29 Mouhijoki

Jolla phone: SFOS 3.1.0 Seitseminen

After having temporarily disabled dev mode before someone else uses my phones, I couldn't re-enable it (won't do that again in the future, for sure).

In Jolla settings-dev mode: progress bar "checking status" displayed for more than 10 minutes, then security code asked for dev mode enabling, then "accept" page, then... nothing (endless static progress bar saying -or not- "installing dev mode")

Of course, no sfos-upgrade or version --dup, as devel-su isn't available.

According to some old topics on similar issues, the culprit could be openssh, so I tried to uninstall it.

With Storeman: Two versions of openssh are shown as "installed" : (i) from NielDK and (ii) from lashs0r, although I never installed the lashs0r version (repository not enabled). Could not uninstall openssh (with or without NielDK repo enabled): endless process.

From terminal: Could not execute pkcon remove openssh => fatal error - this would break your system

pkcon install jolla-settings-sailfishos fails: fatal error - failed to obtain authentication

Tried to disable/enable my jolla account. It didn't help.

Any suggestion?

You can use recovery mode to access the shell as root and repair from there : https://jolla.zendesk.com/hc/en-us/articles/204709607-Jolla-Phone-How-to-use-Recovery-Mode

Once the phone is set to recovery mode and shell is displayed, what would you suggest? version --dup?

Edit: will try Louis' idea tonight.

Solution? Long story anyway:

https://together.jolla.com/question/89476/cannot-re-enable-developer-mode/?answer=190108#post-id-190108 (rewritten by objectifnul, including some English statements translated from French)

While trying to reinstall developer mode I got a warning that a lot of packages had to be downgraded so I ended up solving this problem by doing this:

Entered developer mode by following this: https://jolla.zendesk.com/hc/en-us/articles/360002996893
Running chroot /rootfs as described in the guide above
Setting a root password by running passwd root while in chroot
Rebooting the phone and installing fingerterm in from Storeman/Openrepos
Issuing these commands in terminal:

su (this is the key moment when you become root) pkcon refresh

Louis' suggestion worked well so far, but not further:

pkcon install zypper (fails, but zypper was already installed)

zypper install jolla-developer-mode jolla-settings-system-developermode (fails)

As zypper fails, I entered version --dup instead, after having checked OS release with ssu s Wait for a very long time (one hour or so): refreshing cache, updating list of packages, getting system updates, checking changes... Ends up with an error message I couldn't copy, plus call for reboot
Reboot
Enable developer mode (fails again, after a long "checking status" progress bar, then a static no-progress bar saying "setting up changes")

Trying this after reboot:

Disable all patches then su then zypper install jolla-developer-mode (with answer 'yes' to quit running packagekit)

A bunch of downgrade proposals appears, accept them or ignore if no better choice.

Reboot again.

Re-enable patches, go to Utilities, restart home screen.

Go to jolla settings-developer mode : YESS! dev mode is enabled again.

I admit it's solved, at least for me and for Xperia X. Not sure it's the best workaround for everyone though. An official solution from Jolla system team would be welcome.

I also restored my Jolla phone, with a slightly different method, just using 'su' in the recovery shell to (i) set the root password and (ii) reinstall jolla-developer-mode. Maybe this simple method would also work for the Xperia.
